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 noticed differences between mature and immature long bones at various torsional speeds.
CONCLUSION
The chicken humerus model demonstrated a promising alternative to investigate the effect of bone material properties on the spiral fracture pattern. The intent of this study was to expand it as a suitable bone model for resident teaching and research purpose.
引言
动物骨骼已被用作模拟人类骨骼的模型，用于研究骨折模式和固定技术。本研究旨在使用鸡肱骨模型，研究不同速度的扭转力对人类掌骨螺旋骨折的影响。
材料与方法
解剖30根新鲜冷冻的鸡肱骨，平均分为三组。将骨头安装在定制夹具上，分别以22.5°/秒、30°/秒和45°/秒的不同扭转加载速率进行加载。分析骨折模式、角度和长度。
结果
我们的结果与其他使用成熟动物长骨的研究一致，这些研究表明螺旋骨折形态与扭转速率之间没有相关性。我们还注意到在不同扭转速度下成熟和未成熟长骨之间的差异。
结论
鸡肱骨模型为研究骨材料特性对螺旋骨折模式的影响提供了一种有前景的替代方法。本研究的目的是将其扩展为适合住院医师教学和研究目的的骨模型。
