RESUMEN

BACKGROUND: Although segmental femoral shaft fractures (SFSF) are very challenging to manage, there has been no critical evaluation of the current practices and outcomes. The aim of this study is to evaluate their characteristics, management trends, outcomes, and complications. METHODS: A literature search was conducted via the SCOPUS, Embase (via SCOPUS) and MEDLINE (via PubMed) between 1995 and 2023. Studies were included if they reported patient demographics, mechanism of injury, classification of fractures, associated injuries, type of management, outcomes, and complications. EXCLUSION CRITERIA: only diaphyseal fractures were included and proximal and distal femoral fractures were excluded from this study. RESULTS: Overall, 22 studies met the inclusion criteria reporting on 313 patients. Mean age was 36.2 years with male-female ratio of 4.8 to 1. The majority were high-energy fractures secondary to road traffic accidents and 16% were open. The most commonly associated injuries included chest injury (27%) and lower leg fractures (24%). Treatment consisted of intramedullary nailing (IMN) (72%), plating (22%) or both combined (6%). Outcomes reported: good in 70%, fair in 10%, excellent in 19% and poor in 2% of cases. Mean time to union was 20 weeks. Complications are reported in 24% of cases, with most common delayed union (5%) and non-union (4%). CONCLUSION: SFSF are high-energy fractures occurring most commonly in young males, are open in 16% of cases and have significant associated injuries. In their overwhelming majority, IMN is the mainstay of treatment. The expected outcome is generally good in 70% of cases, although not devoid of complications in 24% of cases and patients must be aware of this during the consent process.

RESUMEN

The incidence of proximal femur fractures is increasing due to aging of the population. Intramedullary nails are the mainstay of treatment for intertrochanteric hip fractures mainly due to their better biomechanical properties compared to dynamic hip screw devices, shorter operative time, and less blood loss during surgery. However intramedullary nail fixation is not devoid of complications. The purpose of this study is to look at complications related to intramedullary nailing for intertrochanteric hip fractures in a major trauma center. A retrospective study was conducted including all patients having suffered an intertrochanteric femur fracture and treated with intramedullary nails from October 1, 2020, to October 1, 2022, in the Orthopaedic Surgery Clinic. The intramedullary hip systems used were the Stryker Gamma3 Nail and the VITUS PF Nail. All complications following the postoperative period were recorded in detail. Overall, 240 patients with a mean age of 82.3 years treated with hip intramedullary devices were identified. Superior cutout of the lag screw in two patients (females 90 and 87 years old) was identified 8 and 10 weeks following initial surgery. Avascular necrosis (AVN) of the femoral head was identified in one patient (male 81 years old) which occurred 12 weeks postoperatively. All three cases were revised by replacing the nail with cemented hemiarthroplasty. Periprosthetic fractures occurred in an 88-year-old male and a 73-year-old female following an injury distal to the stem and were managed by replacing the nail with a long stem device (Long Gamma3). One case of metalwork fracture was also recorded. There are many advantages in managing intertrochanteric hip fractures with intramedullary hip devices such as shorter theater time, less blood loss, and improved biomechanical properties. However, complications such as cutout of the lag screw, AVN, and periprosthetic fracture are serious and require complex revision surgery.

RESUMEN

The coronavirus disease 2019 (COVID-19) pandemic has led to important restrictions in social life of civilians worldwide and there were lower admission rates mainly in surgical departments in many hospitals. This study presents how COVID-19 pandemic affected admissions at the orthopaedic and trauma surgery department of a major trauma center. A retrospective study was conducted that recorded all patients examined at the outpatient orthopaedic clinic and the emergency orthopaedic department, as well as patients admitted to the orthopaedic surgery clinic and patients that underwent operative procedures between March 23 and May 4, 2020 (first lockdown period) and between March 23 and May 4, 2019 (control period). In addition, all patients with hip fractures that required hospitalization and underwent hip surgery were identified during the same time periods. During lockdown period 1 compared with the lock-down period 2 were observed: 70% and 61% decrease in the number of patients examined at the outpatient clinic and the emergency orthopaedic department respectively. The number of patients admitted to the orthopaedic surgery clinic declined by 41%, whereas operative procedures decreased by 22%. Regarding hip fractures timing to surgery during the first period was significantly less compared with second lockdown period, however, hospitalization days remained almost unchanged over the two time lockdown periods. Restrictions during the first lockdown period due to COVID-19 pandemic caused an important decrease in the number of patients and theaters in all orthopaedic departments in one of the major trauma centers in Athens. However, the incidence of hip fractures in elderly was not significantly decreased. Further similar studies are needed to identify variations and patterns of these parameters in other trauma centers.

RESUMEN

PURPOSE: To establish the current peer-reviewed practices in the discipline of orthopaedic surgery and correlate these to the journal's impact factor. Unfortunately, this is not receiving much attention and a critical literature gap in various disciplines; thus, determining the current practices in the discipline of orthopaedic surgery could provide valid insight that may be potentially applicable to other academic medicine disciplines as well. METHODS: Orthopaedic surgery journals belonging to the Journal Citation Reports were queried, and the following was extracted: impact factor (IF) and blinding practices: single (SBPR), double (DBPR), triple (TBPR), quadruple (QBPR), and open (OPR) blinding review process and possibility of author-suggested reviewer (ASR) and non-preferred reviewer (NPR) options. RESULTS: Of the 82 journals, four were excluded as they allowed submission by invitation only. In the remaining, blinding was as follows: SBPR nine (11.5%), DBPR 52 (66.7%), TBPR two (2.6%), QBPR zero (0%), and OPR three (3.8%), and in 12 (15.4%), this was unclear. ASR and NPR options were offered by 34 (43.6%) and 27 (34.6%) journals respectively, whereas ASR was mandatory in eight (10.2%). No correlation between IF and any other parameter was found. CONCLUSION: The rules of the "game" are unclear/not disclosed in a significant number of cases, and the SBPR system, along with the ASR (mandatory sometimes) and NPR, is still extensively used with questionable integrity and fairness. Several recommendations are provided to mitigate potentially compromising practices, along with future directions to address the scarcity of research in this critical aspect of science.

RESUMEN

One of the most important complications of pelvic injuries is hemorrhage which can be attributed to the venus plexus of the pelvis, the damaged bone on the fracture site, or in 15% of cases to arterial cause. In the last case mortality could reach 70%. Clinical case presentation, a 77-year-old man, presented in the emergency department of our hospital hemodynamically unstable due to fall from height (3 meters) with comminuted bilateral fractures of the pubic rami, right sacral and iliac wing fracture, right acetabular fracture, fractures of transverse processes of the first, second, and fifth lumbar spine vertebrae and a periprothetic fracture of the right femur. Advanced trauma life support (ATLS) protocol was followed throughout. Computed tomography (CT) scans and CT angiography performed, showed the above mentioned pelvic fractures that did not require stabilization, without further injuries, and a well described retroperitoneal hematoma without any evidence of active bleeding. During the resuscitation process the patient developed cardiac arrest and cardiopulmonary resuscitation (CPR) protocol was followed. The patient was intubated and retained his cardiac rhythm. However, he remained unstable and an angiography was then performed that revealed internal iliac artery bleeding and embolism of the internal iliac artery was performed. The patient was stabilized and was transferred to the intensive care unit for further management. Arterial hemorrhage due to pelvic injury is less common, however presents with high rates of mortality. CT angiography may in some cases not reveal existing active bleeding, misleading the clinician. Therefore, in patients with high clinical suspicion of arterial pelvic hemorrhage who remain unstable during the initial resuscitation and do not present with other primary source of bleeding, an angiography and embolism should be performed as soon as possible.

RESUMEN

Background: Bilateral acetabular fractures constitute a rare entity, and their optimal management is unknown. Materials and Methods: A systematic literature search was conducted in PubMed, Embase and Cochrane Library between 1995 and 2020. Inclusion criteria were studies presenting cases of bilateral acetabular fractures and reporting outcomes. Extracted data included patient demographics, injury mechanism, fracture classification, associated injuries, management and outcomes. Results: Thirty-seven studies (47 cases; 35 males vs 12 females) were included. Mean age was 46 years old (range 13-84) and mean follow-up was 19.8 months (range 1.5-56). High-energy injuries (49%) and seizures (45%) were the most common injury mechanisms. Fracture type distribution differed according to injury mechanism. Treatment was surgical in 70% of cases (75% open reduction and internal fixation vs 25% acute total hip arthroplasty). Outcomes were excellent/good in 58% of patients. Complications included heterotopic ossification (11%), nerve injury (11%), degenerative arthritis (6%), DVT (6%), and infection (3%). Conclusions: Bilateral acetabular fractures most commonly occur either after trauma or seizures and are commonly managed operatively. They are not devoid of complications, however, more than half (58%) achieve complete functional recovery.

RESUMEN

Fractures of the tibia shaft are the most common long bone fractures, especially in young male adults. Due to specific anatomical features, these fractures are more common than any other long-bone fracture. This is one of the main reasons they are associated with twice the incidences of deep infection compared with any other bone and can be combined with the presence of segmental bone defect. Many reconstruction techniques have been used to manage such cases, including Ilizarov technique, Masquelet technique, vascularized fibula transfer, and the monolateral external fixator. We present a case of a 21-year-old male patient who was admitted to our hospital for a Gustillo type I tibial shaft fracture which was initially treated by an intramedullary nail device. Two months postsurgery the patient presented with clinical signs of infection in the area of the fracture site, confirmed by an osteolytic lesion revealed radiographically. A surgical operation was performed that included a tibial osteotomy proximal to the defected bone, bone excision, and application of a LRS external fixation device. Antibiotic therapy was administrated based grown cultures, and regular follow-up X-ray revaluation was performed. After six months, the bone was radiologically united, the frame was removed, and the leg was protected in a walking boot while the patient used only partial weight bearing. The treatment of segmental bone defects associated with infection and soft tissue loss presents a great challenge, and the choice of the appropriate method requires further study.

RESUMEN

BACKGROUND: There is currently no consensus regarding the optimal type of peritoneal dialysis catheter (PDC). We compared the outcomes of PDCs according to the number of cuffs, intercuff and intraperitoneal segment shape, and presence of a weighted tip. METHODS: A systematic review of the literature was performed using the MEDLINE and Cochrane Library databases (end-of-search date: October 16th, 2019). We included studies comparing double-cuff vs. single-cuff, swan-neck vs. straight-neck, coiled-tip vs. straight-tip, and weighted vs. non-weighted PDCs for the outcomes of interest. We performed meta-analyses using the random-effects model. We assessed the risk of bias using the Newcastle-Ottawa scale and the Cochrane Collaboration's Tool. RESULTS: In total, 38 studies were identified, of which 20 were randomized controlled trials (RCTs) and 18 were observational studies. No statistically significant differences were detected between double-cuff vs. single-cuff, swan-neck vs. straight-neck, and coiled-tip vs. straight tip PDCs in any of the outcomes of interest. Weighted catheters were associated with significantly lower rates of tunnel infection (relative risk [RR] 0.52, 95% confidence interval [CI] 0.31-0.95, p = 0.03), migration (RR 0.07, 95% CI 0.03-0.16, p < 0.001), drainage failure (RR 0.62, 95% CI 0.39-0.96, p = 0.03), cuff extrusion (RR 0.40, 95% CI 0.21-0.74, p < 0.001), and complication-related removal (RR 0.53, 95% CI 0.44-0.64, p < 0.001). DISCUSSION: Among the different types of PDCs, weighted catheters result in lower complication rates and superior long-term outcomes compared to non-weighted catheters. Other aspects of the catheter design do not significantly affect PDC outcomes. PROTOCOL REGISTRATION: PROSPERO 2020 CRD42020158177.
