RESUMEN

Pediatric humerus lateral condyle fractures (PHLCF) are one of the most common fractures among children. PHLCF is approximately 20% of all pediatric elbow fractures. Among the treatment modalities are: nonoperative treatment with splinting, closed reduction with percutaneous K-wire fixation (CRPP), and open reduction with K-wire fixation (ORIF). We aimed to evaluate radiological, functional, and clinical outcomes of Jakob type 2 PHLCF treated either with CRPP or ORIF. We hypothesized that CRPP may be as safe and effective as ORIF for Jakob type 2 PHLCF. In this retrospective study, we included patients with Jakob type 2 PHLCF operatively treated in a single center. Patients with multiple fractures or open fractures were excluded from the study. 69 patients between ages 2 and 12 were included and they were divided into two groups. Group 1 included the patients treated with CRPP, whereas Group 2 included the patients treated with ORIF. Demographical, radiological, clinical, and functional parameters were evaluated. Average duration of surgery ( P < 0.001), initial displacement ( P = 0.014), and duration of admission ( P < 0.001) were significantly less in group 1. Group 2 had significantly higher percentage of left-sided injury than group 1 ( P = 0.038). Average varus deformity score was significantly higher in group 1 ( P = 0.014). CRPP was associated with shorter duration of surgery and hospital stay. Functional, clinical, and radiological outcomes were identified similar between CRPP and ORIF for Jakob type 2 PHLCF. CRPP may be as safe and effective as ORIF for Jakob type 2 PHLCF.

RESUMEN

OBJECTIVES: This study aims to evaluate the histopathological, biochemical, and functional effects of N-acetylcysteine (NAC), which has antioxidant, anti-inflammatory, and cytoprotective activity, on nerve regeneration in rats with sciatic nerve crush (axonotmesis) injury. MATERIALS AND METHODS: This study used 16 male Wistar rats, which were divided into treatment and control groups. A standard axonotmesis-type surgical injury was induced in the left sciatic nerves of all rats. The treatment group was given 300 mg/kg of intraperitoneal NAC once a day, whereas the control group received an equal volume of saline solution. After conducting gait analyses, the sciatic functional index (SFI) was used for functional assessment. After gait analysis, all animals were euthanized. Blood samples were examined biochemically. The left sciatic nerves and left triceps surae muscles were examined histopathologically. RESULTS: Histopathologically, the thickness of the perineurium, axonal degeneration, axonolysis, edema, inflammation, muscle atrophy, and muscle degeneration were all significantly lower in the treatment group (p<0.05). Functionally, SFI-1, SFI-2, and SFI-3 were significantly higher in the treatment group (p<0.05). Biochemically, while the native thiol level and native thiol/total thiol ratio were significantly higher in the treatment group (p<0.003), the disulfide/total thiol ratio was significantly higher in the control group (p<0.005). Significant correlations were found between six of the seven gait parameters and the histopathological findings (p<0.05). CONCLUSION: Our study results suggest that NAC may contribute positively to the histopathological and functional recovery of sciatic nerve injury in rats. Furthermore, NAC may have an antioxidant effect on thiol-disulfide homeostasis at a biochemical level. We believe that NAC has a stimulatory effect on healing following nerve injuries.

RESUMEN

We investigated oxidative status in patients with rotator cuff tendinopathy (RCT) and evaluated their relationship with radiological and clinical parameters. In this cross-section study, 88 patients with RCT (59 males and 29 females) and 86 healthy controls (66 males, 20 females) were enrolled. The sample consisted of nontraumatic patients who are suffering from shoulder pain because of rotator cuff disease, which was established by clinical tests and MRI scanning. Oxidative stress in patients with RCT was analyzed via the dynamic thiol/disulfide homeostasis (TDH). Thiol/disulfide homeostasis was measured by a new colorimetric method. Furthermore, oxidative stress was indirectly measured by serum total oxidant status (TOS), oxidative stress index (OSI), and total antioxidant capacity (TAC). Serum disulfide levels and the other oxidative stress parameters of the RCT group were significantly greater than those of the control group (P < .001 for all), whereas the anti-oxidative stress parameters remained unchanged (P > .05 for all). The lowest and highest serum disulfide levels were detected in patients with grades 1 and 3, respectively (P < .001). Furthermore, in a multiple regression analysis, the disulfide/natural thiol ratio (ß=-4.886, P = .004) and the MRI grading (ß=0.314, P=.001) were independently associated with the Western Ontario Rotator Cuff Index WORC score. We found an association between the levels of various serum markers of oxidative injury, especially serum disulfide levels, and the increasing severity of RCT. Thiol/disulfide homeostasis seems to play a critical role in RCT, both in the beginning and during the progression of disease.

RESUMEN

OBJECTIVE: The incidence of postoperative morbidity and mortality in hip fracture patients is high and is associated with nutritional deficiencies. This study investigated the predictive value of preoperative prognostic nutritional index (PNI) on postoperative intensive care unit (ICU) requirement and mortality in geriatric hip fracture patients. METHODS: Geriatric (≥65 years old) hip fracture patients who underwent surgery between January 2021 and September 2023 were evaluated retrospectively. Patients were classified according to the unit followed in the postoperative period (service group and ICU group) and 28-day mortality (mortality group and survivor group). The predictive value of PNI for ICU requirement and mortality and the factors affecting ICU requirement and mortality were investigated. RESULTS: The study included two hundred twenty-two patients, and 66.2% (n=147) were women. In the postoperative period, 47.7% (n=106) of the patients were followed in the ICU and 52.3% (n=116) in the inpatient service. The 28-day mortality of the patients was 6.8% (n=15). PNI was found to be significantly lower in patients followed in the ICU (group ICU) than in those followed in the service (group S) and in patients who died (group mortality) compared to those who lived (group survivor) (p<0.001 and p=0.029, respectively). In multivariate regression analysis, high American Society of Anesthesiologists (ASA) status and low PNI were determined to be independent risk factors for ICU requirement. Acute Physiology and Chronic Health Assessment II score was an independent predictor of mortality. In ROC curve analysis, the cut-off value of PNI in predicting mortality was 32.5, and the area under the curve was 0.660 (95% CI, 0.516-0.803). CONCLUSION: In geriatric hip fracture patients, preoperative PNI value can be used, like ASA status, in determining postoperative ICU requirements. Nutritional deficiencies are associated with adverse postoperative outcomes in this patient group, and low PNI values (<32.5) help predict in-hospital mortality.

RESUMEN

BACKGROUND: This study compares the efficacy and safety of lateral approach surgery with and without radial nerve dissection in treating humeral diaphyseal fractures. It assesses clinical, radiological, and complication outcomes, providing a description of the surgical methods and perioperative benefits. METHODS: We retrospectively analyzed data from 71 patients admitted between May 2015 and December 2022 who underwent lateral approach surgery for humeral diaphyseal fractures. Group 1, consisting of 34 patients without radial nerve dissection, and Group 2, comprising 37 patients with radial nerve dissection, were compared. Parameters such as age, gender, fracture side (right/left), fracture type, follow-up time, surgical duration, blood loss, radiological and clinical evaluations (including Shoulder-Elbow range of motion [ROM] and Quick Disabilities of the Arm, Shoulder, and Hand score [Q-DASH]), and complications were examined. Surgical techniques and outcomes were documented. RESULTS: Both groups exhibited comparable distributions in age, gender, fracture types, and follow-up times (p>0.05). Group 1 demonstrated significantly lower surgical duration and blood loss compared to Group 2 (p<0.05 for both). Clinical assessment revealed satisfactory shoulder and elbow ROM within functional limits for all patients, with no instances of infection. Q-DASH scores were similar between groups. Postoperative radial nerve palsy occurred in one patient in Group 1 and three patients in Group 2, with all cases resolving uneventfully during outpatient follow-ups. Radiological assessment confirmed uneventful union in all patients. CONCLUSION: Lateral approach surgery without radial nerve dissection for humeral diaphyseal fractures offers comparable effectiveness and safety to conventional surgery, with potential perioperative advantages such as reduced operation time and blood loss.

RESUMEN

OBJECTIVES: The aim of this study was to compare the radiological and clinical results of femoral diaphyseal fractures operated in the lateral decubitus position with those operated in the supine position on a traction table and to detail the perioperative surgical technique. PATIENTS AND METHODS: Between October 2018 and January 2022, in this prospective, randomized, and single-blind comparative study, 75 patients diagnosed with adult femoral diaphyseal fractures to whom intramedullary nails were applied were operated in the lateral decubitus position without a traction table (Group 1, 37 patients) and in the supine position with a traction table (Group 2, 38 patients). Preoperative age, gender, fracture mechanism, fracture type, and surgical waiting times were determined. Perioperative anesthesia type, surgery preparation time, surgical time, number of fluoroscopy doses, amount of bleeding, and type of reduction were evaluated, and detailed observational descriptions of the surgical techniques were made. In the postoperative period, radiological evaluations were made with x-ray radiography and orthoroentgenogram, while in the clinical evaluation, hip-knee joint range of motion and rotational evaluation were made with the Craigs test. Follow-up periods were determined and complications noted. RESULTS: The average age was 32 in Group 1 and 28 in Group 2, the female/male ratio was 1:36 in Group 1 and 5:33 in Group 2, and the follow-up period was 18.2 months Group 1 and 21.7 months in Group 2. No significant difference was detected between the groups in terms of age, gender, fracture mechanism, fracture type, anesthesia type, surgical waiting time, and follow-up period (p > 0.05). Compared to Group 2, the shorter preparation time, surgical time, and number of fluoroscopy doses in Group 1 were found to be statistically significant (p < 0.05). The differences in the amount of bleeding and need for open reduction were not statistically significant between the groups (p > 0.05), and no statistical difference was found in joint range of motion and rotational evaluation in clinical evaluation in both groups (p > 0.05). There was no significant difference in terms of complications between groups. CONCLUSIONS: We found the lateral decubitus method without a traction table to be a safe and effective alternative to the supine method with a traction table in terms of the radiological and clinical results and that it also has the advantages of shortening the surgical time, reducing radiation exposure. LEVEL OF EVIDENCE: Level 1 prospective, randomized, single-blind controlled study.

RESUMEN

OBJECTIVES: The aim of this study was to evaluate the bending strength of plate-screw fixation augmented with titanium elastic nails (TENs) in a simple long bone fracture model using lamb cadaver femurs. MATERIALS AND METHODS: A total of 24 lamb cadaveric femurs that were osteotomized transversely from the mid-diaphysis with a bone saw were used to obtain a simple fracture model. The femurs were divided randomly into three groups. In Group 1, only plate-screw was used for fixation. In Group 2, plate-screw fixation was augmented with a 2.5-mm TEN. In Group 3, plate-screw fixation was augmented with two 2.5-mm TENs. Each bone model was positioned on a mechanical testing machine. Subsequently, three-point bending loads were applied to each bone to measure the force required for failure at the osteotomy site. The data were recorded on a computer connected to the test device and the bending strengths of all samples were calculated. RESULTS: There was no statistically significant difference in the bending strength (megapascals) between Groups 1 and 2 or between Groups 2 and 3 (p>0.05). However, the bending strength in Group 3 was significantly higher than in Group 1 (p<0.05). CONCLUSION: The application of intramedullary TEN during surgery in long bone fractures, combined with a bridge plate, may be helpful to strengthen the fixation stability.

RESUMEN

INTRODUCTION: This study aimed to compare the radiological and clinical results of VP and EF applications in multi-fragmented radius distal intra-articular fractures (AO type C) in our clinic. METHODS: We retrospectively analysed 80 patients who underwent surgery for radius distal fracture (AO type C) between 2014 and 2020. Group 1 comprised patients who were treated with VP, and Group 2 comprised patients who were treated with EF. Radiological evaluation was performed by measuring radial inclination, radial length, volar tilt, intra-articular step-off and ulnar variance by two-way radiography. The clinical findings were evaluated using the Gartland and Werley scoring system, and complications were noted. RESULTS: There were no statistically significant differences between the two groups in terms of age, gender, side, fracture subtypes and follow-up time (p > 0.05). There were no statistically significant differences between the two groups in radiological parameters (based on cut-off values) (p > 0.05). The clinical evaluation did not reveal a statistically significant difference between the two groups (p = 0.613). CONCLUSION: EF is as successful as VP in providing radiological cut-off values. EF treatment can be used as an effective and safe alternative method for multi-fragmented radius distal intra-articular fractures.

RESUMEN

Background: The purpose of this study was to evaluate the possible risk factors that are related with mortality at third and twelfth months after hip fractures in a large population of patients aged 80 years and older. Methods: 605 patients were evaluated in terms of the localization of the fracture, gender, age, side of the fracture, the type of applied procedure, anesthesia type, hospitalization time, time to operation, comorbidities, ASA score, the values of preoperative hemoglobin, lymphocyte and neutrophil percentage, white blood cell, albumin, sodium levels. The state mortality system was used to investigate whether patients are alive or died. Statistical analysis was performed to evaluate the important factors on third- and twelfth-month mortality. Results: Male gender, neurologic-cardiac-chronic obstructive pulmonary (COP) diseases, preoperative hemoglobin level < 10 g/dL, arthroplasty and external fixator groups, ASA grade ≥ 3, delaying the surgery more than 4 days, longer hospitalization time, lower albumin levels and advanced age were found to be statistically significant factors for 3-month mortality (p values were; 0.01, 0.02, 0.01, 0.01, 0.047, 0.01, 0.02, 0.002, < 0.001, 0.002 and 0.01, respectively). Male gender, hypertension-neurologic-cardiac diseases, preoperative hemoglobin level < 10 g/dL, delaying the surgery more than 4 days, longer hospitalization time, lower lymphocyte percentage, lower albumin levels and advanced age were found to be statistically significant factors for 12-month mortality (p values were; < 0.001, 0.01, 0.01, 0.01, 0.03, 0.01, < 0.001, 0.01, 0.004 and < 0.001, respectively). Conclusion: COP, advanced age, and heart disease were the most important factors in 3-month mortality. Long hospitalization time, male gender and advanced age were the most important factors affecting the 12-month mortality.Level of Evidence Prognostic level IV.

RESUMEN

PURPOSE: It is known that the incidence of paediatric orthopaedic trauma peaks in the summer months as a result of increased and uncontrolled physical activity. The aim of this study was to review the experience of a single centre with paediatric orthopaedic traumas and determine the relationship between the severity and the variations in the incidence of traumas in relation to the seasons and temperatures during the study period. MATERIALS AND METHODS: A single institutional review of the historical data of all patients aged 0-16 years who presented for orthopaedic trauma between January 2018 and December 2020 in the emergency department of Level 1 tertiary orthopaedic trauma centre was conducted. 65,182 paediatric orthopaedic trauma cases had been retrieved from the hospital data base during the 3 -year study period. We classified the traumas according to the variants of the patients' and by holidays, seasons, school days and weekends, months and in which part of the body it occurred. RESULTS: After excluding the summer vacation, 77% of paediatric orthopaedic trauma patients attended to the hospital on weekdays and 23% on weekends. While it was observed that hot weather had a statistically positive effect on trauma attendance, rainy weather had an negative effect (p < 0.05). Trauma attendances were found to be statistically higher in summer months, except for injuries that may occur with indoor activities such as metacarpal fracture, phalanx fracture and pulled elbow (p < 0.05). CONCLUSION: Orthopaedic trauma at a Level 1 tertiary health care trauma center do vary significantly with the weather and are highest in the summer season. Therefore, it should focus more attention on preventive strategies for paediatric trauma in the summer season.

RESUMEN

BACKGROUND: Although pilon fractures are rare, they are important for orthopedic surgeons because of the difficulty of their treatment and their adverse effects on gait function. The aim of this was study to evaluate the relationship between the reduction quality of the fracture, functional results, ankle arthrosis, and plantar pressure distribution in patients with tibia pilon fractures. METHODS: In this study, a total of 62 patients treated for an intraarticular pilon fracture in our clinic between January of 2015 and January of 2019 were evaluated retrospectively. Postoperative reduction qualities of the patients were evaluated with the Ovadia-Beals criteria; ankle functional scores were evaluated with the Teeny-Wiss score; and ankle arthrosis was evaluated with the Takakura classification. At the last patient follow-up, foot loading analysis was performed, and the results were evaluated for their relation with postoperative reduction quality, ankle function, and ankle arthrosis. RESULTS: There were 62 patients (50 men and 12 women). The average age was 43.3 years (range, 19-78 years). The mean follow-up was 34.3 months (range, 24-58 months). The mean Ovadia-Beals score was 12.35 ± 4.6 on the postoperative plain radiographs of the patients; the mean Teeny-Wiss score at the last follow-up was 76.82 ± 17.69; and the mean Takakura score was 1.47 ± 1.35. Based on the pedobarographic measurements, 47.58% of the patients put weight on the anterior portion and 52.42% on the posterior portion of the foot in the anteroposterior plane. In the mediolateral plane, 42.15% loaded on the medial portion of the ankle and 57.85% loaded on the lateral portion of the foot. CONCLUSIONS: Intra-articular tibia pilon fractures can be demonstrated by lateralization of the walking axis and changes in gait patterns and can be associated with clinical outcome.

RESUMEN

BACKGROUND: The aim of the study is to determine the rate of acute kidney injury (AKI) after hip fracture surgery over the age of 80 and to investigate the factors associated with AKI. METHODS: From January 2015 to January 2020, 589 patients who underwent surgery of hip fractures at our institution were retrospectively reviewed. Serum creatinine (sCr) was analysed daily pre- and postoperatively during the hospital stay. Patients were divided into groups; AKI and non-AKI based on KDIGO (Kidney Disease Global Outcomes) criteria. The incidence, risk factors, and mortality of postoperative AKI were investigated. RESULTS: Out of 589 patients, 58 developed an AKI (9.8%). Smoking (p: 0.004), pre and postoperative low albumin level (p < 0.05), pre- and postoperative high potassium level (p < 0.05), pre- and postoperative high urea levels (p < 0.05), high amount of intra-operative bleeding (p: 0.003) and prolonged surgery time (p: 0.003) were found to be risk factors associated with AKI. Although the mortality rate was higher in the AKI group, it was not statistically significant (p > 0.05). CONCLUSION: AKI is a temporary but common complication following hip fracture surgery, which can also be predicted if risk factors are adequately observed. It typically increases the length of hospital stays, mortality and morbidity. LEVEL OF EVIDENCE: Level III evidence, Retrospective comparative study.

RESUMEN

OBJECTIVES: Using proximal femoral nailing (PFN) in the lateral decubitus (lateral) position may be an option when no traction table is available. We hypothesized that applying PFN would be effective and reliable in the lateral position without a traction table. To test our hypothesis, we compared the two techniques in a prospective, randomized controlled study. PATIENTS AND METHODS: Eighty patients (> 60 years of age) with unstable intertrochanteric fractures were randomly operated on prospectively in the lateral position without a traction table (Group 1) or in the supine position with a traction table (Group 2) between April 2018 and April 2019. We compared the surgery preparation time, total anesthesia time, duration of surgery, fluoroscopy exposure time, and amount of bleeding between the two procedures. The type-apex distance (TAD), collodiaphyseal angle (CDA), reduction quality, and lag quadrant were measured radiologically. The Harris Hip Score (HHS) was also calculated. RESULTS: The mean follow-up time was 18.5 (14-27) months in Group 1 and 19.9 (14-27) months in Group 2. The mean follow-up time, mean age, sex distribution, and fracture pattern were similar between the groups. The preparation time and total anesthesia time of Group 2 were longer than those of Group 1, and the fluoroscopy time of Group 2 was shorter than that of Group 1 (p < 0.05). No significant differences in surgical time, bleeding amount, TAD, CDA, target lag quadrant, reduction quality, or the HHS were observed between the two groups. CONCLUSIONS: We concluded that PFN is a safe and effective alternative for the treatment of unstable intertrochanteric femoral fractures when a traction table is not available in the operating room.

RESUMEN

Background: Distal chevron osteotomy (DCO) is commonly performed in hallux valgus surgery. The fixation of the osteotomy is provided by various implants. The usage of biodegradable implants such as magnesium is gradually increasing due to the advantages they provide. In this study, we aimed to compare the fixation of DCO with magnesium or titanium screw biomechanically. Methods: Twenty sawbones were used. The samples were divided into two equal groups, including ten sawbones for fixation with single headless titanium (group-1) or magnesium screw (group-2). DCO and screw fixations were performed on all samples using the same technique. Biomechanical testing was applied to five samples in each group in cantilever and the other five in a physiological configuration using a computer connected to the electromechanical test machine. The obtained data were evaluated using the Shapiro-Wilk test, Student's t-test and Mann-Whitney U test on the IBM® SPSS (Statistical Package for the Social Sciences) V22.0 software. Significance was accepted at the p < 0.05 level. Results: There was no statistically significant difference between the magnesium screw and the titanium screw in terms of maximum force, maximum displacement and stiffness measurements in cantilever and physiological loadings (p > 0.05 for all). Conclusion: This study found no significant difference in biomechanical stability between the magnesium and titanium screws in DCO fixation on sawbones. Further studies with real bones are needed.

RESUMEN

BACKGROUND: This present study was designed to evaluate the effect of restrictions on fracture admission to a Level-1 tertiary trauma hospital between COVID-19 pandemic and pre-pandemic restriction time intervals that included groups of younger than <20-years-old, 20-65-years-old, and older than aged >65-years-old. METHODS: Patients who were hospitalized and treated for orthopedic treatment between 10 March and 1 June during the pandemic period were retrospectively analyzed. Control group consisted of patients admitted to the hospital in the same time interval in 2019. The patients were divided into three groups, under 20 years of age, between 20 and 65 years of age, and over 65 years of age. The patients' data included age, gender, trauma mechanism, fracture type, and any COVID-19 radiological or clinical symptoms. RESULTS: The number of patients >65-years-old admitted to the orthopedic trauma center was high at pandemic intervals compared to pre-pandemic time. When the groups were compared for patients of 20-65-years-old; there was a significant difference for the fracture type (p<0.05). Lower extremity fractures were high at pre-pandemic group, whereas multiple traumas were high at pandemic group. For sub-group 20-65 ages, low-energy traumas were higher at pre-pandemic group, whereas high-energy traumas were more frequent at the pandemic group. CONCLUSION: We observed a decrease in fracture admission to orthopedic trauma centers during COVID-19 pandemic for subgroups of <20-years-old and 20-65-years-old ages, whereas there was a significant increase for >65-years-old age, most of them related to the osteoporotic hip fractures. So that older age group should be encouraged to mobilize at home and have permission to walk and make physical activity to avoid osteoporosis for a limited time daily.

RESUMEN

OBJECTIVES: In this study, we present the use of case specific three-dimensional (3D) printed plastic models and custom-made acetabular implants in orthopedic surgery. MATERIALS AND METHODS: Between March 2018 and September 2020, surgeries were simulated using plastic models manufactured by 3D printers on the two patients with pilon fractures. Also, custom-made acetabular implants were used on two patients with an acetabular bone defect for the revision of total hip arthroplasty (THA). RESULTS: More comfortable surgeries were experienced in pilon fractures using preoperative plastic models. Similarly, during the follow-up period, the patients that applied custom-made acetabular implants showed a fixed and well-positioning in radiographic examination. These patients did not experience any surgical complications and achieved an excellent recovery. CONCLUSION: Preoperative surgical simulation with 3D printed models can increase the comfort of fracture surgeries. Also, custom-made 3D printed acetabular implants can perform an important task in patients treated with revision THA surgery due to severe acetabular defects.

RESUMEN

OBJECTIVES: In this mechanical study, we aimed to compare two different screw trajectories in terms of durability against axial loads on oblique scaphoid fractures using composite bone models. MATERIALS AND METHODS: Oblique osteotomies were made along the dorsal sulcus of 14 composite scaphoid bone models. Following this, all bone models were randomly classified. One group of bones were fixed with a screw placed perpendicular to the osteotomy line and the other group was fixed with a screw placed centrally down the long axis of the scaphoid bone. Each scaphoid bone model was positioned on a mechanical testing machine. Subsequently, axial loading tests were applied on each bone model to measure the amount of loading required to cause 2-mm displacement and failure on the osteotomy side and maximum displacement at the time of failure on scaphoid bone models. RESULTS: There was no statistically significant difference in load to 2-mm displacement and failure between the two groups (p>0.05). Also, there was no statistically significant difference between the two groups in terms of maximum displacement seen on failure (p>0.05). CONCLUSION: In our study, we found that the stability of the screws which laid perpendicular to the fracture line and parallel to the long axis of the scaphoid was the same in fixing oblique scaphoid fractures.

RESUMEN

AIM: To evaluate the surgical outcomes and complications of patients over 65 years of age, with unstable ankle fractures. MATERIAL AND METHOD: The study included 111 patients (73F/38 M) operated on between January 2015 and February 2019 and followed up for a mean of 21.2 months (range, 6-62 months).Demographic characteristics, comorbidities, fracture type, and mechanisms of injury were evaluated. Relationships between postoperative complications and comorbidities were examined. In the postoperative functional evaluations, the AOFAS score was used and pre and postoperative mobilization (eg, use of assistive devices) was assessed. RESULTS: The mean age of the patients was 70.5 ± 6.1 years (range, 65-90 years). The mechanism of trauma was low-energy trauma in 90.1% of the fractures and high-energy trauma in 9.9%. The fractures were formed with a SER injury (supination external rotation) in 83.7% of cases and bimalleolar fractures were seen most frequently (85/111, 76%).Complications developed in 16 (14.4%) patients and a second operation was performed in 11 (9.9%) patients with complications. Plate was removed and debridement was performed in 5 of 6 patients due to wound problems. Nonunion was developed in the medial malleolus in 4 patients. Revision surgery was performed because of implant irritation in 2 patients and early fixation loss in the medial malleolus fracture in one patient. Calcaneotibial arthrodesis was performed in 3 patients because of implant failure and ankle luxation associated with non-union. A correlation was determined between ASA score and DM and complications, but not with osteoporosis. The mean follow-up AOFAS score was 86.7 ± 12.5 (range, 36-100).A total of 94 (84.7%) patients could walk without assistance postoperatively and 92 (82.9%) were able to regain the preoperative level of mobilization. CONCLUSION: Although surgery can be considered an appropriate treatment option for ankle fractures in patients aged >65 years, care must be taken to prevent potential complications and the necessary precautions must be taken against correctable comorbidities.

RESUMEN

Aim This study aims to analyze the spectrum, management, and outcome of Syrian refugees' fracture over four-year period, highlighting challenges in management and follow-up. Methods This was a retrospective review of Syrian refugee patients operated for fractures at our centre from January 2015 to January 2019. The patients were evaluated for age, gender, mechanism of injury, location and type of fracture, presence of accompanying injuries, surgical technique, complications, mortality and morbidity. The comparison of complications and postop outpatient clinic controls between Turkish citizens and Syrian refugees were also evaluated. Results The study included a total of 455 patients comprising 281 adults (202 males, 79 females) with a mean (SD) age of 41.1 (19.3) years and 174 children with a mean age of 8.8 (4.9) years. The trauma mechanism was most commonly fall in both adult and pediatric patients (86.6% / 73.5%). Whilst lower limb fractures were more common in adults (73.7%), upper limb fractures were more common in children (63.4%). The presence of accompanying trauma was determined in 21 (7.5%) adults and 10 (5.7%) children. Multiple fractures were determined in 12 (4.3%) adults and eight (4.6%) children. Plate fixation (PF) was most used in 137 (48.8%) adult patients and K-wire augmentation was used in 75 (43.1%) pediatric patients. Out of the 455 patients, 41 (14.6%) adults and 13 (7.3%) children developed complications. Whilst three adult patients were died during follow-up, no deaths were recorded in the pediatric patients. Complication rate was 54/455 in Syrian refugees and 32/455 in citizens. It was observed that the complication was significantly higher in immigrants (p: 0.017). Sixty-five (14.2%) Syrian immigrants did not come to the outpatient clinic control at all or once, while this rate was 29/455 (6.3%) for Turkish citizens (p = 0.012). Conclusion Inadequate living conditions and lack of communication faced by refugees reduce the rate of patient follow-up and negatively affect the results of orthopedic trauma.

RESUMEN

OBJECTIVE: The aim of this study was to immunohistochemically identify and characterize the presence of sensory nerve endings (SNEs) in pulvinar, ligamentum teres (LT), and hip joint capsule (HJC) of children with developmental dysplasia of the hip (DDH). METHODS: Pulvinar, LT, and HJC specimens were obtained from 38 hips of 36 children (31 girls, five boys; mean age=49 months; age range=18-132 months) during open reduction surgery for DDH. All specimens underwent subsequent routine tissue processing (formalin fixation and paraffin embedding). To determine tissue morphology, haematoxylin and eosin staining was used. SNEs were analyzed immunohistochemically using a mouse monoclonal antibody against S-100 Beta Protein based on the classification of Freeman and Wyke including four types of SNEs including mechanoreceptors: type I Ruffini corpuscles, type II Pacini corpuscles, type III Golgi organs, and type IVa unmyelinated free nerve endings (FNEs). Additionally, children were sorted into three groups based on their age at the time of surgery: Group 1 (age <3 years; 19 hips of 18), Group 2 (age: 3-5 years; 10 hips of 10 children), and Group 3 (age >5 years; 9 hips of 8 children). RESULTS: Although no Type I, II, or III SNEs were identified in any specimen, type IVa mechanoreceptor (FNEs) was immunohistochemically characterized in 13 (34%) pulvinar, 19 (50%) LT, and 16 (42%) HJC specimens. The total density of FNEs was 3.31±5.70)/50 mm2 (range 0-21) in pulvinar specimens, 3.18 ± 5.92)/50 mm2 (range 0-24) in HJC specimens, and 4.51±6.61/50 mm2 (range 0-22) in LT specimens. Furthermore, the operated side, gender, and the number of FNEs in specimens did not differ significantly among the age groups (p>0.05 for all), and the number of FNEs was not significantly correlated with age, gender, or the operated side (p>0.05 for all). CONCLUSION: Evidence from this study revealed that pulvinar, LT, and HJC include only FNEs, which play a role in pain sensation, among mechanoreceptors. Surgical excision of these tissues may not cause a significant loss of sensory function in the hip joint of children with DDH. LEVEL OF EVIDENCE: Level II, Therapeutic Study.
