Biomechanical evaluation of spiral fracture in human metacarpal using chicken humerus model.

ABSTRACT:

Introduction

Animal bones have been used as a model to mimic human bones for investigation of fracture patterns and fixation techniques. This study aims to investigate the effects of torsional forces of varying speeds on the spiral fracture in human metacarpal using a chicken humerus model.

Materials and methods

Thirty fresh-frozen chicken humerus bones were dissected and equally divided into three groups. The bones were mounted onto a customized jig and subjected to different torsional loading rate at 22.5°/s, 30°/s and 45°/s, respectively. The fracture pattern, angle and length were analysed.

Results

Our results concurred with other studies that used mature animal long bones which showed no correlation between spiral fracture morphology and torsional rate. We also n
