Classfication of Hip Fractures: Neck of Femur, Intertrochanteric, and Subtrochanteric Fractures

Nepal Orthopedic Association Journal | 2025 | Laxman Rijal

Fractures around the hip are common injuries seen in orthopedic practice, particularly in the elderly population. These fractures include femoral neck, intertrochanteric, and subtrochanteric fractures. These fractures are often associated with significant morbidity, mortality, and socioeconomic burden due to prolonged immobilization and loss of independence in physiologically a...

A Novel Internal Fixation Design for the Treatment of AO/OTA‐31A3.3 Intertrochanteric Fractures: Finite Element Analysis

Orthopaedic Surgery | 2024 | Xiaofeng Chen, Miaotian Tang, Xiaomeng Zhang, Yichong Zhang

ObjectiveAO/OTA 31‐A3.3 intertrochanteric fracture is the most unstable type of intertrochanteric fracture, with a high rate of postoperative complications and implant failure. We have designed a new intramedullary fixation, proximal femoral totally bionic nail (PFTBN), for the treatment of A3.3 intertrochanteric fracture. To test its biomechanical performance, we adopted the m...

Fracture reduction has a dominant effect over cerclage wiring in increasing stiffness of intertrochanteric OTA/AO 31-A3.1 (reverse oblique) fractures managed with cephalomedullary osteosynthesis

OTA International: The Open Access Journal of Orthopaedic Trauma | 2021 | Wayne Hoskins, Sheldon Moniz, Robert Day, Alex Hayes

Abstract Objectives: To investigate the mechanical properties of cephalomedullary nailing of intertrochanteric OTA/AO 31-A3.1 (reverse oblique) fractures and to test the hypothesis that anatomical reduction and augmentation with cerclage wire produces a more stable construct. Methods: A standardized fracture model in composite saw bone was created to stimulate an intertrochaner...
