Mismatch between Conventional Femoral Arthroplasty Stems and Hip Morphology in the Elderly Chinese Hip Fracture Population.

Introduction: The morphology of the proximal femur differs in various populations. Based on our clinical experience, conventional femoral stems used in hip arthroplasty do not fit the Chinese population well. Hence, this study aims to evaluate the suitability of conventional femoral stems in the elderly Chinese hip fracture population requiring hip arthroplasty and to establish if gender and age related differences exist within this population.

Intramedullary nailing of abnormally bowed atypical femoral shaft fractures: surgical technique.

The treatment of atypical femoral shaft fractures with abnormal bowing provides a unique challenge for surgeons. Whilst intramedullary fixation of atypical femoral shaft fractures affords both mechanical and biological benefits, the mismatch between standard intramedullary devices and the abnormal femoral bowing in these patients makes this method of fixation challenging for the surgeon. The purpose of this manuscript is to illustrate the evolution of our surgical technique through a series of four patients.
