Comparative finite element analysis of three implants fixing stable and unstable subtrochanteric femoral fractures: Proximal Femoral Nail Antirotation (PFNA), Proximal Femoral Locking Plate (PFLP), and Reverse Less Invasive Stabilization System (LISS).
The optimal type of fixation implant for managing subtrochanteric fractures (STFs) is debated, as uncertainty continues to surround the comparative biomechanical performance of the proximal femoral nail antirotation (PFNA), proximal femoral locking plate (PFLP), and reverse less invasive stabilisation system (LISS). No studies have used finite element analysis (FEA) to compare these three devices. The objective of this study was to use FEA to compare the PFNA, PFLP, and LISS used to treat STFs based on the following criteria: (1) stress distribution on the femur and implant, (2) peak stress and stress on the medial side of the femur near the fracture site, and (3) smallest axial displacement of the femoral head. ⋯ IV, basic science study.

Rotator cuff integrity and shoulder function after intra-medullary humerus nailing.
Antegrade percutaneous intra-medullary nailing (IMN) has a poor reputation in the treatment of humerus fractures. The aim of the present study was to assess rotator cuff integrity and shoulder function after IMN in humerus fracture. ⋯ IV, retrospective study.

Assessment of the Quality and Reliability of the Information on Rotator Cuff Repair on YouTube.
YouTube® has become a common health information source for patients. Recent studies have determined that videos on YouTube® contain misleading and inappropriate information for different medical conditions. The aim of the present study was to assess the quality and reliability of videos pertaining to rotator cuff (RC) repair surgery. ⋯ IV, Case series.

Efficacy of bone-end intervention on fracture healing in bisphosphonate-related atypical femoral fractures.
Delayed unions are quite common in the treatment of atypical femur fractures, which are thought to result from the long-term use of bisphosphonates. The effects of interventions for sclerotic tissue on the fracture line in atypical femoral fractures are not fully known. For this reason, we compared the results of patients with atypical femoral fractures treated by closed intramedullary nailing to patients treated by open surgery accompanied with interventions for their sclerotic bone ends, aiming to answer: (1) In the treatment of atypical femoral fractures, do bone-end interventions have a positive effect on the radiological union rate and radiological union time? (2) Do bone-end interventions influence complication rates in the treatment of atypical femoral fractures? ⋯ III, retrospective case-control study.

Observational StudyScrew-plate fixation for displaced middle-third clavicular fractures with three or more fragments: A report of 172 cases.
Although mid-shaft clavicular fractures are generally thought to be non-serious injuries that nearly always heal with non-operative treatment, recent studies found non-union rates of 3%-7% in simple fractures and 20%-33% in complex fractures. The primary objective of this study was to report the functional and anatomical outcomes after screw-plate fixation of displaced mid-shaft clavicular fractures with three or more fragments. ⋯ IV, retrospective cohort study.
