Review Meta AnalysisPostoperative outcomes of tranexamic acid use in geriatric trauma patients treated with proximal femoral intramedullary nails: A systematic review and meta-analysis.
Recently, there has been a series of clinical studies focusing on the perioperative administration of tranexamic acid (TXA) in geriatric trauma patients undergoing proximal femoral intramedullary nail surgery. However, the safety and efficacy of TXA in these patients remains controversial. Therefore, we performed a systematic review to focus on two questions: (1) would TXA reduce perioperative blood loss in geriatric trauma patients undergoing proximal femoral intramedullary nail surgery? and (2) would TXA increase the rate of perioperative complications in geriatric trauma patients undergoing proximal femoral intramedullary nail surgery? ⋯ II, Systematic review and Meta-analysis.

Biomechanical comparison of minimally invasive treatment options for Type C unstable fractures of the pelvic ring.
The definite treatment of pelvic C fractures presents a widely discussed issue and undergoes continuous evolution. While the stabilization of the posterior ring has been studied extensively, the fixation of the anterior pelvic ring continuous to be rarely investigated. The importance of the simultaneous stabilization however lays in the earlier mobilization and prevention of long-term damage to the pelvis. Therefore we investigated four combinations of minimally invasive fixation techniques for unstable type C1-3 pelvic injuries and aimed to answer the following research questions: (1) what combination of fixation methods yields the highest stiffness and the least displacement? (2) Is the combination of a single sacroiliac screw (SI-screw) with a transiliac internal fixator (TIFI) a reasonable alternative to two SI-screws? (3) Is a modified unilateral anterior fixation comparable to a retrograde transpubic screw? ⋯ III, comparative in vitro study.

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.

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.

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.
