RESUMEN

BACKGROUND: The pertrochanteric femoral fracture (PFF) represents one of the most common fracture types throughout Germany. To enable early mobilization of patients, the primary surgical goal is load-stable osteosynthesis. Implant failure still represents the largest group of implant-related complications (>80%). OBJECTIVE: The aim of the study was to document and analyze the influence of the implant on the functional outcome and an evaluation of the rotationally stable screw anchor (RoSA) vs. Gamma3 nail. MATERIAL AND METHODS: In a retrospective study 43 patients with PFF (AO 31A1-A3) were included in the study. The influence of the implant on the functional outcome was assessed by 2 standardized questionnaires (SF-36, NMS (New Mobility Score)) and analyzed in a retrospective evaluation. RESULTS: In the study no significant differences in functional outcome scores ≥ 1 year after osteosynthesis of the PFF could be shown depending on the implant used. There is an overall tendency for a better outcome in the G3N group. DISCUSSION/CONCLUSION: In the literature the superiority of intramedullary nailing over extramedullary implants is continually discussed. Implant failure is still the most frequent complication. In intramedullary implants, such as the G3N, the primary cause is failure of the head-neck component. For conventional extramedullary implants the biomechanical properties on the femoral shaft also pose a challenge in the case of unstable PFF. The further development of the RoSA to an intramedullary implant could combine the advantages of intramedullary load carriers with the advantages of the blade-screw combination in the head-neck fragment and lead to a reduction in implant-associated complications.

RESUMEN

BACKGROUND: Proximal femoral fractures in geriatric patients are a major challenge in orthopedics, often leading to major functional impairment. Early surgical intervention is crucial for improving patient recovery and overall health outcomes. Thus, Japan's Ministry of Health, Labour and Welfare initiated a reimbursement policy in April 2022 to encourage early surgery for these fractures in patients aged ≥75 years. This study investigated the impact of this policy on early surgery rates in Japan and identified factors influencing the timing of surgical interventions. METHODS: We retrospectively analyzed the data of patients who underwent surgery for proximal femoral fractures at our institution between April 2022 and March 2023. Patients were categorized into two groups based on the timing of surgery relative to the injury: ≤48 h and >48 h. Demographic and clinical data, including age, sex, fracture type, and various health- and admission-related factors, were assessed. RESULTS: Of the 192 patients, 152 were included in the study. Among them, 38% underwent early surgery (≤48 h), and 15% of the patients arrived more than 48 h post-injury. Significant differences were found in admission routes and residence types between the groups. The ≤48 h group had shorter intervals from injury to admission and surgery than the >48 h group. Factors such as the admission process, day of the week, and C-reactive protein levels significantly influenced the timing of surgery. CONCLUSIONS: After introducing incentives for early surgery in Japan, 38% of patients with proximal femoral fractures underwent surgery within 48 h of injury. Factors contributing to patients not receiving early surgery included transport from another hospital, weekend hospitalization, and elevated CRP levels. These findings suggest that achieving surgery within 48 h of injury is challenging through hospital efforts alone, and the time criteria might be more appropriate if changed to "admission to surgery."

RESUMEN

The numbers of osteoporotic fractures will increase due to the demographic change, which particularly affects the proximal femur, pelvis, proximal humerus, wrist and vertebral column. Surgical treatment is superior to conservative treatment of proximal femoral fractures. Non-dislocated fractures of the wrist can also be treated with a plaster cast but studies suggest that the results in the first 12 months are better after surgical treatment. The situation is similar for fractures of the proximal humerus and non-dislocated fractures in particular can also be treated conservatively. A score and classification were recently developed for making decisions on the treatment of osteoporotic vertebral fractures. Fractures of the anterior and posterior pelvic ring can be treated conservatively with the patient under sufficient analgesia as long as there is no substantial dislocation. The highest priority in geriatric traumatology is fast remobilization.

RESUMEN

BACKGROUND: Proximal femoral fractures are severe injuries in geriatric patients. Additionally, geriatric patients are at a high risk of death due to coronavirus disease 2019 (COVID-19). OBJECTIVE: To identify predictors of mortality in geriatric patients with COVID-19 and concurrent proximal femoral fractures. MATERIAL AND METHODS: Patients who underwent surgical treatment for proximal femoral fractures and also tested positive for COVID-19 were included. The age, gender, the American Society of Anesthesiology (ASA) score and the admission from a nursing home were considered as variables. The rate of reoperations, the mortality at 3 months and discharge home were evaluated as outcomes. RESULTS: In this study 46 patients with COVID-19 (female/male 31/15, median age 87.0 years with an interquartile range [IQR] of 9.8 years) met the inclusion criteria. Of these, 32 patients (69.6%) had to be cared for in the intensive care unit and 26 patients (56.5%) had a severe course of COVID-19 with pneumonia. The median length of hospital stay for survivors was 19 (IQR 17.5) days and 4 of the patients (8.7%) required surgical revision. The in-hospital and 3­month mortality were 40.0% (n = 17) and 43.5% (n = 20), respectively. The factors which influenced the in-hospital and 3­month mortality rates were admission from a nursing home, the presence of pneumonia (increased the risk of death) and female gender (protective). CONCLUSION: The occurrence of COVID-19 in patients with proximal femoral fractures has a high mortality. Admission from a nursing home and the presence of pneumonia increased the risk of death, whereas women were at lower risk.

RESUMEN

Background Hip fracture is a public health problem globally, and it poses one of the biggest challenges in healthcare due to its associated complications. Objectives The aim of this study is to investigate the quality of life in adult patients in Khartoum State, Sudan, after they have undergone treatment using a gamma nail for proximal femoral fractures. Methodology This cross-sectional descriptive hospital-based study was conducted at Ibrahim Malik, Omdurman, and Bahri Teaching Hospitals over six months, from April to October 2022. The data were collected using an interview questionnaire that covered relevant aspects of the study. The data were analyzed using IBM SPSS Statistics for Windows, V. 26.0 (IBM Corp., Armonk, NY). The study was approved by the Sudan Medical Specialization Board, and ethical clearance was obtained. Results The study included 37 patients. More than half of the patients (59.5%, n=22) were women. The mean age of cases was 66.7 years (standard deviation, ±15.6). The mean time from the time of the fracture to the time of surgery was eight days (±15). Twenty-three (62.2%, n=23) (JRB1) of the patients started weight bearing on the second postoperative day. Regarding the health-related quality of life, 21.6% of the patients had a good health-related quality of life, 67.6% had a fair health-related quality of life, and 10.8% had a poor health-related quality of life. None of the patients reported an excellent quality of life. Based on the Oxford Hip Score, 54.1% of the patients had satisfactory joint function, 29.7% had mild to moderate hip joint function, 13.5% had moderate to severe hip joint function disturbance, and one patient (2.7%) had severe hip joint function problems. Conclusion In this study, the vast majority of the patients who underwent gamma nail surgery for hip fracture had quality of life scores in the fair to good range afterward. The results indicate that nailing is associated with good outcomes regarding quality of life and is an acceptable option for femoral fracture surgeries in Sudan.

RESUMEN

The S3 guidelines on the prophylaxis, diagnostics and treatment of osteoporosis 2023 were completely revised and updated between 2021 and 2023 in accordance with the Association of the Scientific Medical Societies of Germany (AWMF) regulations. The guideline committee consisted of delegates from the 20 specialist societies of the Umbrella Organization Osteology (Dachverband Osteologie, DVO) as well as delegates from the German Society of General Medicine and Family Medicine (DEGAM), the German Society for Nephrology (DGfN) and the Federal Self-help Association for Osteoporosis (BfO).The guidelines focus on preventive measures, diagnostic procedures and treatment approaches for osteoporosis in men aged 50 years and over and postmenopausal women. The main aim is the optimization of care processes, reduction of fracture incidences and maintenance or improvement of the quality of life and functional capacity of patients affected by fractures. A major update to the guidelines includes the introduction of a new risk calculator that can take more risk factors (n = 33) into account and that can estimate the risk of vertebral body and proximal femoral fractures for a 3-year period (previously 10 years). This results in new thresholds for diagnostics and treatment. The programmed app is currently not yet certified as a medical product and a paper version is therefore currently available for patient care with the planned integration of a web-based version of the risk calculator. From the perspective of trauma surgery, the recommendations and innovations for manifest osteoporosis are of particular clinical importance. The focus of the DVO guidelines update is therefore on the implementation of secondary fracture prevention in trauma surgery, orthopedic and geriatric traumatology in the clinical and practical daily routine.

RESUMEN

Introduction: Proximal femoral fractures in aging populations represent a significant concern, with an increasing prevalence among individuals aged ≥100 years. The existing research does not provide robust guidance for clinicians managing older patients aged ≥100 years with proximal femoral fractures. We investigated the safety and efficacy of surgical treatment in patients aged ≥100 years with proximal femoral fractures and evaluated the impact of early surgery on their outcomes. Methods: This retrospective cohort study involved 15 patients aged ≥100 years who underwent surgical treatment of proximal femoral fractures; the control group included 137 patients in their 90s. Data were collected between January 2010 and December 2017. Evaluation items included patient characteristics, surgical details, perioperative complication rates, length of hospital stay, the proportion of patients discharged to the same facility or home, rate of regaining walking ability, and 1-year survival rate. Results: The patients aged ≥100 years and those in their 90s had comparable outcomes. Thus, age alone does not dictate surgical success. Early surgery (≤48 h) was associated with trends toward improved perioperative complications, ambulatory ability, and return to original living environment. Discussion: This study underscores the potential benefits of surgical intervention for proximal femoral fractures in patients aged ≥100 years, indicating the relevance of early surgery (≤48 h). Our findings emphasized the importance of timely intervention and evidence-based decision-making for this demographic. Clinicians, policymakers, and patients could benefit from our insights to enhance fracture management strategies, along with future research endeavors to validate and expand our results in larger multicenter cohorts.

RESUMEN

Aim Significant risk factors for femoral nail cutout are well-documented, primarily in the context of single-screw proximal nails. However, it remains uncertain whether those same risk factors are applicable when considering different implant devices. The aim of this retrospective cohort study was to compare cutout risk factors between single- versus double-screw proximal femoral nails. Methods Patients over the age of 75 with intertrochanteric femur fractures (AO Classification 31-A1 or 31-A2) were included in the multicentre study. A study group was treated with a double-screw nail, while a control group received single-screw device. Demographic data, surgical time (min), fracture pattern, distal locking, reduction quality, comorbidities, tip-apex distance (TAD) and 12-month functional scores was collected. Results Two hundred patients were enrolled, 100 for each group. Nine patients experienced a cutout complication, five in the study and four in the control group. The main differences were in distal locking configurations (p<0.05) and in TAD values (p<0.05). The TAD value was higher in the study than in the control group (30.40±0.89 versus 26.79±1.79). No differences at 12-month follow up were reported according to functional scores. Conclusion This study provides insights into the choice of nail systems for intertrochanteric femur fractures, highlighting the importance of distal locking configurations and TAD values. The double screw nail exhibits quite a tolerance by having a higher average TAD value. These findings may guide clinical decisionmaking in the treatment of this challenging fracture type.

RESUMEN

BACKGROUND: Proximal femoral fractures represent the most frequent fracture entity in Germany accounting for more than 20% of all fractures. According to a decision of the Federal Joint Committee from 2019, proximal femoral fractures also have to be surgically treated within 24 h. In order to quantify a subjectively perceived increase in workload in trauma surgery at a supraregional trauma center, a retrospective analysis of the number of surgically treated proximal femoral fractures was performed. Proximal femoral fractures were chosen due to their high incidence and homogeneous treatment. METHODS: Using ICD-10 codes, all surgically treated proximal femoral fractures from 2016 to 2022, including the patient's zip code, were retrieved from the database of the trauma center. RESULTS: The number of surgically treated proximal femoral fractures doubled from 2016 to 2022. The highest increase (60%) was recorded from 2020 to 2022. Heat maps show an increase in the catchment area radius as well. CONCLUSION: When compared (inter)nationally, a disproportionate increase in the amount of surgically treated proximal femoral fractures was recorded at the trauma center studied. The increase of the catchment area radius and the number of patients treated in the urban area show that less and less hospitals participate in emergency treatment. Possible explanations are a lack of resources aggravated by the recent COVID-19 pandemic and a lack of qualified personnel, interface problems between the federal states or the strict requirements of the Federal Joint Committee in the treatment of proximal femoral fractures. It must be assumed that there is a clearly increased workload for all professions involved in the trauma center investigated, although the infrastructure has remained unchanged.

RESUMEN

BACKGROUND: Proximal femoral factures (PFFs) constitute a heavy medical, social, and economic burden. Overall, orthopaedic conditions vary widely in France regarding the patients involved and treatments applied. For PFFs specifically, data are limited. Moreover, the ongoing expansion of geriatric orthopaedics holds promise for improving overall postoperative survival. The objectives of this retrospective study of a nationwide French database were: 1) to describe the pathway of patients with PFFs regarding access to care, healthcare institutions involved, and times to management; 2) to look for associations linking these parameters to post-operative mortality. HYPOTHESIS: Across France, variations exist in healthcare service availability and time to management for patients with PFFs. MATERIAL AND METHODS: A retrospective analysis of data in a de-identified representative sample of statutory-health-insurance beneficiaries in France (Échantillon généraliste des bénéficiaires, EGB, containing data for 1/97 beneficiaries) was conducted. All patients older than 60 years of age who were managed for PFFs between 2005 and 2017 were included. The following data were collected for each patient: age, management method, Charlson's Comorbidity Index (CCI), home-to-hospital distance by road, and type of hospital (public, non-profit private, or for-profit private), and time to surgery were collected. The study outcomes were the incidence of PFF, mortality during the first postoperative year, changes in mortality between 2005 and 2017, and prognostic factors. RESULTS: In total 8026 fractures were included. The 7561 patients had a median age of 83.8 years and a mean CCI of 4.6; both parameters increased steadily over time, by 0.18 years and 0.06 points per year, respectively (p<10-4 for both comparisons). Management was by total hip replacement in 3299 cases and internal fixation in 4262 cases; this information was not available for 465 fractures. The overall incidence increased from 90/100,000 in 2008 to 116/100,000 in 2017 (p=0.03). Of the 8026 fractures, 5865 (73.1%) were managed in public hospitals (and this proportion increased significantly over time), 1629 (20.3%) in non-profit private hospitals (decrease over time), and 264 (3.3%) in for-profit private hospitals. The home-to-hospital distance ranged from 7.5 to 38.5km and increased over time by 0.26km/year (95% confidence interval [95%CI]: 0.15-0.38) (p<10-4). Median time to surgery was 1 day [1-3 days], with no significant difference across hospital types. Mortality rates at 90 days and 1 year were 10.5% (843/8026) and 20.8% (1673/8026), respectively. Two factors were significantly associated with day-90 mortality: the CCI (hazard ratio [HR], 1.087 [95%CI: 1.07-1.10] [p<10-4]) and time to surgery>1 day (HR 1.35 [95%CI: 1.15-1.50] [p<0.0001]). Day-90 mortality decreased significantly from 2005 to 2017 (HR 0.95 [95%CI: 0.92-0.97] [p<10-4]), with no centre effect. CONCLUSION: The management of PFF in patients older than 60 varied widely across France. Time to surgery longer than 1 day was a major adverse prognostic factor whose effects persisted throughout the first year. This factor was present in over half the patients. Day-90 mortality decreased significantly from 2005 to 2017 despite increases in age and comorbidities. LEVEL OF EVIDENCE: IV Retrospective cohort study.

RESUMEN

BACKGROUND: Global prevalence of osteoporosis and fragility fractures is increasing due to the aging population. Proximal femoral fractures are among the most common orthopedic conditions in elderly that significantly cause health deterioration and mortality. Here, we aimed to evaluate the mortality rates and risk factors, besides the functional outcomes after these injuries. METHODS: In a retrospective cohort study, all patients admitted with a femoral neck or intertrochanteric fracture between 2016 and the end of 2018 were enrolled in this study. Medical records were reviewed to include patients over 60 years of age who had a proximal femoral fracture and had a complete medical record and radiographs. Exclusion criteria included patients with pathological fractures, cancer under active treatment, follow-up loss, and patient access loss. Demographic and clinical features of patients alongside the details of fracture and patient management were recorded and analyzed. In-hospital and post-discharge mortalities due to included types of fractures at one and 12 months were the primary outcome. Modified Harris Hip Scores (mHHS) was the measure of functional outcome. RESULTS: A total of 788 patients including 412 females (52.3%) and 376 males (47.7%) with a mean age of 76.05 ± 10.01 years were included in this study. Among patients, 573 (72.7%) had an intertrochanteric fracture, while 215 (27.3%) had a femoral neck fracture, and 97.1% of all received surgical treatment. With a mean follow-up of 33.31 months, overall mortality rate was 33.1%, and 5.7% one-month and 20.2% 12-months rates. Analysis of 1-month mortality showed a significant mortality difference in patients operated after 48 h of fracture (p = 0.01) and in patients with American Society of Anesthesiologists (ASA) scores of 3-4 compared to ASA scores of 1-2 (p = 0.001). One-year mortality data showed that the mortality rate in femoral neck fractures was lower compared to other types of fracture. Surgical delay of > 48 h, ASA scores of 3-4, and treatment by proximal femoral plate were associated with shorter survival. The overall mean mHHS score was 53.80 ± 20.78. CONCLUSION: We found several risk factors of mortality, including age ≥ 80 years, a > 48-hour delay to surgery, and pre-operative ASA scores of 3-4 in patients with proximal femoral fracture. Furthermore, the use of a proximal femoral plate was a significant risk factor for mortality and lower mHHS scores.

RESUMEN

BACKGROUND: Regional anesthesia (RA) techniques such as femoral nerve block (FNB) or fascia iliaca compartment block (FICB) are effective analgesia techniques in the treatment of pain from proximal femoral fractures (PFF). While in Great Britain (GB) these are already frequently used in the emergency department for preoperative analgesia, in the German-speaking D­A-CH area (Germany, Austria, Switzerland) this seems to occur much less frequently. Therefore, the aim of this study was to survey the type and frequency of RA procedures used and to compare international practice. MATERIAL AND METHODS: In the D­A-CH area as well as in GB, registered emergency departments were contacted and invited to participate in an online survey. The survey included questions on the frequency and type of RA procedures, reasons for non-use, equipment used, person performing the procedure and medications used. RESULTS: The participation rate was 17.4% (142/818 emergency departments). RA procedures for preoperative analgesia in PFF were used in 18.3% (21/115) of hospitals in the D­A-CH region and in 96.3% (26/27) in GB. The most commonly used block was the FICB in GB at 96.2% (25/26) and the FNB in Germany at 66.7% (14/21). In the D­A-CH area, RA procedures are primarily performed by anesthesiology specialists 71.4% (15/21), and in GB by emergency department residents 65.4% (17/26). DISCUSSION: RA procedures are still performed too rarely following PFF in emergency departments in the D­A-CH area. In international comparison with GB there is potential for improvement.

RESUMEN

BACKGROUND: Little is known about the incidence of haematoma, and clinical correlates among orthogeriatric patients. AIMS: This study aims to describe the incidence of haematoma after surgical repair of hip fracture and to identify the clinical correlates of haematoma among orthogeriatric patients. METHODS: Two orthopaedic surgeons and a dedicated operator using ultrasound technique, each other in blindness, evaluated 154 orthogeriatric patients during their hospital stay. All patients received a comprehensive geriatric assessment. We investigated the concordance between clinical diagnosis and ultrasound detection of haematoma, and then we explored the clinical correlates of the onset of post-surgical haematoma. RESULTS: Blood effusion at the surgical site was detected in 77 (50%) patients using ultrasound technique; orthopaedic surgeons reached a clinical agreement about post-surgical haematoma in 18 (23%) patients. The sensitivity of clinical evaluation was 0.66, and the specificity was 0.70. Independent of age, clinical, pharmacological, and surgical confounders, proton pump inhibitors (PPIs) were associated with post-surgical haematoma (OR 2.28; 95% CI 1.15-4.49). A tendency towards association was observed between selective serotonin reuptake inhibitors and post-surgical haematoma (OR 2.10; 95% CI 0.97-4.54), CONCLUSIONS: Half of older patients undergoing surgical repair of proximal femoral fracture develop a post-surgical haematoma. Clinical assessment, even if made by senior orthopaedic surgeons, underestimates the actual occurrence of post-surgical haematoma compared to ultrasound detection. Ultrasound technique may help to detect haematoma larger than 15 mm better than clinical assessment. PPIs's use is a risk factor for post-surgical haematoma independent of several medical and surgical confounders.

RESUMEN

PURPOSE: The aim of this study was to determine how Charlson comorbidity index (CCI) predicts the 10-year survival of operatively treated hip fracture patients aged ≥ 65 years. METHODS: This retrospective cohort study included all consecutive patients who had a hip fracture and were operatively treated upon in the study period from 01 January 2007 to 31 December 2007 at the university hospital. The clinical patient data were obtained from the medical records, and CCI score was calculated. The CCI predicts the 10-year mortality for a patient who may have a range of 22 comorbid conditions. Cumulative survival and complications were evaluated in terms of gender. RESULTS: A total of 241 hip fractures were studied; of these, 183/241 (76%) were females. A total of 32/241 (15%) complications were found, of which 26/241 (11%) were considered major. Overall, 213/241 (88%) patients died during the 10 years of follow-up. Cumulative survival estimates for females were 13% at 10 years (SE = 0.3, 95% CI 3.8-4.8), and for males, it was 12% at 10 years (SE = 0.5, 95% CI 2.8-4.6) (p = 0.33). CCI was significantly associated with mortality after the hip fracture as patients with CCI scores ≥ 4 were at a 3.1-8.5 times higher risk of death compared to patients with low CCI scores of 2-3 (p < 0.001). CONCLUSION: Complications are common after operatively treated hip fracture. Advanced age, living in a care facility, ASA class 4 and high CCI score ≥ 4 were risk factors of mortality after the operatively treated hip fracture.

RESUMEN

PURPOSE: This study aimed to estimate the survival rate after proximal femoral fracture insult and identify the subgroup of centenarians with a high risk. METHODS: Records of patients (≥ 65 years) who underwent surgery for PFF between 2006 and 2020 were retrieved from the electronic databases of three hospitals. Overall, 22 demographic, perioperative, and postoperative variables were analyzed for all patients > 99 years of age. The effect of anemia, time to surgery, surgical procedure, place of residence, and dementia on complications and survival were evaluated. RESULTS: The study included 85 patients (women n = 71; men n = 14; median age, 100 years; range 100-106 years). Over the study period, the prevalence of centenarians with PFF increased (0.94%). The overall complication rate was 28% (in-hospital death, n = 16; infection, n = 1; hematoma, n = 1; implant failure, n = 1; cardiac decompensation, n = 3; pneumonia with delirium, n = 1; urinary tract infection, n = 1). The 30-day, 3-month, 6-month, and 1-year mortality rates for the study group were 27.1%, 42.4%, 55.3%, and 61.2%, respectively. Median survival was 150 days (range 1-1942 days). Patients with dementia (n = 47) had a shorter survival time than patients without dementia (n = 38) (hazard ratio 1.75; 95% confidence interval 1.04, 2.95). Preoperative anemia, time to surgery, or necessary surgical procedure had no impact on survival. CONCLUSIONS: The prevalence of centenarians undergoing surgery for PFF is increasing. In-hospital mortality is high, and dementia is a risk factor impacting survival. The rates of surgical revision and general complications are low, and the chosen predictors had no significant impact on these outcomes. The survival rate after discharge from hospital seems to be comparable to the estimated survival rate of uninjured centenarians.

RESUMEN

INTRODUCTION: bisphosphonates are used for the management of postmenopausal osteoporosis with high risk of fracture, glucocorticoid-induced osteoporosis, Paget's disease and hypercalcemia; as well as an adjuvant for the management of hyperparathyroidism. Bisphosphonates have been associated with previously unknown adverse effects, including atypical femur fractures. OBJECTIVE: to analyze the relationship of the history of bisphosphonate (BF) use as a risk factor for presenting atypical femur fractures (AFF). MATERIAL AND METHODS: patients aged 40 years or older from two hospital centers seen from 2009 to 2018 for femur fracture were included. The radiographic studies of 441 records were reviewed, from which the fracture site was defined. Subtrochanteric (SF) and diaphyseal (DF) femur fractures were analyzed applying the criteria of the second report of the American Society for Bone and Mineral Research for case definition of AFF. Finally, the consumption of bisphosphonates in these groups was investigated to estimate a measure of association. RESULTS: of the 441 clinical records, 98 (22.2%) were male and 343 (77.7%) were female with a mean age of 77.8 (40-103) years. Fifty-nine FS/FD were identified, of which 53% (31 records) were categorized as AFF. BF use was determined in 80.6% of patients with AFF and 3.57% in FS/FD. BF use was significantly associated with the presence of AFF (OR: 112, p 0.000, CI 95%: 12.6-1001). CONCLUSIONS: BF use significantly increases the risk of presenting AFF. AFF in patients who used BF occurred after a minimum consumption of 24 months.

INTRODUCCIÓN: los bifosfonatos se usan para el manejo de osteoporosis postmenopáusica con riesgo elevado de fractura, osteoporosis inducida por glucocorticoides, enfermedad de Paget e hipercalcemia; así como coadyuvante para manejo del hiperparatiroidismo. Los bifosfonatos se han asociado a efectos adversos previamente desconocidos dentro de los que se encuentran fracturas de fémur de trazo atípico. OBJETIVO: analizar la relación del antecedente de uso de bifosfonatos (BF) como factor de riesgo para presentar fracturas atípicas de fémur (FAF). MATERIAL Y MÉTODOS: se incluyeron pacientes de 40 años o más de dos centros hospitalarios atendidos desde 2009 a 2018 por fractura de fémur. Se revisaron los estudios radiográficos de 441 registros, de los cuales se definió el sitio de fractura. Se analizaron las fracturas de fémur subtrocantéricas (FS) y diafisarias (FD) aplicando los criterios del segundo reporte de la American Society for Bone and Mineral Research para la definición de caso de FAF. Finalmente, se indagó el consumo de bifosfonatos en estos grupos para para estimar una medida de asociación. RESULTADOS: de los 441 registros clínicos, 98 (22.2%) fueron del sexo masculino y 343 (77.7%) del femenino, con edad promedio de 77.8 (40-103) años. Se identificaron 59 FS/FD, de las cuales 53% (31 registros) fueron catalogadas FAF. El consumo de BF se determinó en 80.6% de pacientes con FAF y en 3.57% con FS/FD. El uso de BF se asoció significativamente con la presencia de FAF (OR: 112, p 0.000, IC 95%: 12.6-1001). CONCLUSIONES: el uso de BF aumenta significativamente el riesgo de presentar FAF. Las FAF en pacientes que usaron BF se presentó tras un consumo mínimo de 24 meses.

RESUMEN

AIMS: Factors associated with high mortality rates in geriatric hip fracture patients are frequently unmodifiable. Time to surgery, however, might be a modifiable factor of interest to optimize clinical outcomes after hip fracture surgery. This study aims to determine the influence of postponement of surgery due to non-medical reasons on clinical outcomes in acute hip fracture surgery. METHODS: This observational cohort study enrolled consecutively admitted patients with a proximal femoral fracture, for which surgery was performed between 1 January 2018 and 11 January 2021 in two level II trauma teaching hospitals. Patients with medical indications to postpone surgery were excluded. A total of 1,803 patients were included, of whom 1,428 had surgery < 24 hours and 375 had surgery ≥ 24 hours after admission. RESULTS: Prolonged total length of stay was found when surgery was performed ≥ 24 hours (median 6 days (interquartile range (IQR) 4 to 9) vs 7 days (IQR 5 to 10); p = 0.001) after admission. No differences in postoperative length of hospital stay nor in 30-day mortality rates were found. In subgroup analysis for time frames of 12 hours each, pressure sores and urinary tract infections were diagnosed more frequently when time to surgery increased. CONCLUSION: Longer time to surgery due to non-medical reasons was associated with a higher incidence of postoperative pressure sores and urinary tract infections when time to surgery was more than 48 hours after admission. No association was found between time to surgery and 30-day mortality rates or postoperative length of hospital stay.Cite this article: Bone Joint J 2022;104-B(12):1369-1378.

RESUMEN

Objective: The objectives of this study are 1) to biomechanically compare six different intramedullary fixations for basicervical fracture (AO 31-B3, Type 2 in area classification) and transcervical shear fracture (AO 31-B2.3, Type 1-2 in area classification) using the finite element (FE) method, and 2) to investigate the effects of two different unstable fracture types on fixation. Methods: FE models of two different types of proximal femoral fractures are constructed from CT scan images of a patient with osteoporosis. The fracture models are fixed with a short femoral nail with a single lag screw, short femoral nail with a single blade, and short femoral nail with double lag screws, and then fixed with long femoral nails for each of the three nail types. Subsequently, the maximum loads during walking and stair climbing, as well as the minimum principal strain and compressive failure elements are calculated to assess the fixation of each implant. Results: In both fracture types, the long nail with double lag screws show the smallest volume of compressive failure elements (basicervical fracture, 2 mm3; transcervical shear fracture, 217 mm3). In all types of implants, the volume of the compressive failure elements is larger in the transcervical shear fracture than in the basicervical fracture. A similar trend is observed for the minimum principal strain (compressive strain). Conclusion: The present study shows that a long nail with double lag screws is the most fixative intramedullary nail device for basicervical fracture and transcervical shear fracture in any condition. Furthermore, it is shown that transcervical shear fracture is considerably more unstable than basicervical fracture.

RESUMEN

Abstract: Proximal femoral fractures (PFFs) are among the main causes of hospitalization of elderly patients. They are often challenging to manage at the perioperative stage, which is why appropriate monitoring is recommended in order to prevent and - whenever possible - avoid tforeseeable complications (infections, bedsores, bronchopneumonia, psychicological deterioration and worsening general conditions), reduce the mortality rate, facilitate functional recovery and restore the patient's ability to walk and return to everyday life activities and a normal family context. PFFs constitute a major adverse event for elderly patients, often over the age of eighty and with possible issues arising from a substantially unstable and deficient biological balance, with negative repercussions on their quality of life, longer hospitalization and higher healthcare costs. The COVID-19 pandemic has severely impacted the healthcare systems of virtually all world countries, giving rise to serious operational management difficulties (e.g. surgical staff shortages, less availability of surgical facilities, reassignment of surgical staff to other tasks, the need to convert facilities into intensive care units and dedicated COVID + operating rooms, reconfiguration of pathways and procedures with longer anesthesiological and surgical preparation times, environmental sanitation, etc.). All such factors have prolonged waiting times for surgery, causing higher complications rates especially in fragile patients. It is essential to operate through a timely multidisciplinary approach for PFF patients, who must be treated surgically as soon as possible in order to limit the risk of secondary complications due to prolonged bed rest and facilitate a rapid functional recovery.

RESUMEN

Background: During the COVID-19 emergency, the incidence of fragility fractures in elderly patients remained unchanged. The management of these patients requires a multidisciplinary approach. The study aimed to assess the best surgical approach to treat COVID-19 patients with femoral neck fracture undergoing hemiarthroplasty (HA), comparing direct lateral (DL) versus direct anterior approach (DAA). Methods: A single-center, observational retrospective study including 50 patients affected by COVID-19 infection (30 males, 20 females) who underwent HA between April 2020 to April 2021 was performed. The patients were allocated into two groups according to the surgical approach used: lateral approach and anterior approach. For each patient, the data were recorded: age, sex, BMI, comorbidity, oxygen saturation (SpO2), fraction of the inspired oxygen (FiO2), type of ventilation invasive or non-invasive, HHb, P/F ratio (PaO2/FiO2), hemoglobin level the day of surgery and 1 day post operative, surgical time, Nottingham Hip Fractures Score (NHFS) and American Society of Anesthesiologists Score (ASA). The patients were observed from one hour before surgery until 48 h post-surgery of follow-up. The patients were stratified into five groups according to Alhazzani scores. A non-COVID-19 group of patients, as the control, was finally introduced. Results: A lateral position led to a better level of oxygenation (p < 0.01), compared to the supine anterior approach. We observed a better post-operative P/F ratio and a reduced need for invasive ventilation in patients lying in the lateral position. A statistically significant reduction in the surgical time emerged in patients treated with DAA (p < 0.01). Patients within the DAA group had a significantly lower blood loss compared to direct lateral approach. Conclusions: DL approach with lateral decubitus seems to preserved respiratory function in HA surgery. Thus, the lateral position may be associated with beneficial effects on gas exchange.
