Objectives: There is no consensus as to whether internal fixation or hemiarthroplasty is more appropriate for the treatment of intertrochanteric femur fractures in elderly patients. While the latter offers early mobilization, internal fixation preserves the hip joint and avoids long-term complications associated with the prosthesis. This retrospective study aimed to compare the early results of these treatment modalities.
Methods: The study included 81 patients who were available for follow-up after surgery for intertrochanteric femur fractures. Of 38 patients (mean age 77.7 years; range 65 to 99 years) treated with internal fixation, 25 were alive; of 43 patients (mean age 80 years; range 67 to 97 years) treated with hemiarthroplasty, 22 were alive at the last follow-ups. The two groups were compared with regard to perioperative characteristics, mobilization time, complications, mortality, and daily activities according to the Barthel Activities of Daily Living Index. The mean follow-up was 22.7 months (range 6 to 39 months) in internal fixation, and 22.3 months (range 7 to 39 months) in hemiarthroplasty groups.
Results: Subsequent to the operation, mortality occurred in 34.2% after a mean of 13 months (range 1 to 36 months) and in 48.8% after a mean of six months (range 1 to 24 months) in patients treated with internal fixation and endoprosthesis, respectively. There were no significant differences with respect to mobilization in bed, standing, weight bearing without support, complications, and daily activity scores. The only significant difference in favor of hemiarthroplasty was that full weight bearing with two crutches took a shorter time (p<0.05).
Conclusion: Short-term results suggest that hemiarthroplasty is not an advantageous alternative to internal fixation; moreover, its postoperative survival is shorter and mortality rate is higher. Osteosynthesis seems to be the first choice in the treatment of elderly patients with intertrochanteric femur fractures.

Clinical and radiological comparisons of isolated posterior malleolar fractures treated surgically and conservatively.

Background: Isolated posterior malleolar (PM) fractures are rare fractures without consensus regarding treatment decisions and functional outcomes. The study aims to compare the clinical and radiological results of patients treated surgically or conservatively for isolated PM fractures.
Methods: The study included 30 patients who presented with an isolated PM fracture and were treated conservatively (n = 15) or with surgery (n = 15).
Over-resection, or under-resection, of the femoral cam lesion in patients having hip arthroscopy for femoroacetabular impingement syndrome indicate different possible solutions.

As surgeons, we strive to recognize and correct any mistakes that may occur before completing an operation, and importantly, do our best to avoid irreversible mistakes. Over-resection of the femoral cam lesion in patients having hip arthroscopy for femoroacetabular impingement syndrome has been considered irreversible. While cam under-resection is a technical complication of femoroacetabular impingement surgery to be avoided, avoiding this at the expense of over-resection of the proximal femur is of great concern.

Cardiac implantable electronic devices (CIEDs), including pacemakers, implantable cardiac defibrillators (ICD), and cardiac resynchronization therapy (CRT) devices, regulate heart rate and rhythm in patients with cardiac conditions. With an aging population, CIED-related complications, especially pacemaker pocket infections, are rising. Risk factors include frailty, older age, and superficial device fixation, while risk mitigation involves larger pocket sizes, submuscular fixation, and absorbable antibacterial envelopes.

Introduction: Bilateral simultaneous rotational ankle fractures are an unusual phenomenon that remains unreported in the English literature, and to our knowledge, about 10 cases have been reported. The aim of the study was to evaluate and report clinical outcomes of bilateral simultaneous ankle fractures in our institution.
Case Reoprt: We conducted a review of our 2-year experience with patients who had simultaneous bilateral fractures of the ankles and were treated at our institution.

Introduction: Inferior or subacromial dislocation of the distal clavicle is a rare entity. Previous reports of this injury pattern have largely been limited to Rockwood VI acromioclavicular joint (AC) dislocations, with the distal clavicle located in the subcoracoid position. Few case reports have been described with the inferior clavicle being located in the subacromial space, and these have all been previously associated with clavicle fractures.
