Abstract

This study examines the impact of metacarpal osteotomy at varying directions and angles. Using hand CT-DICOM data from fresh frozen cadavers, 3D models were created and analyzed with finite element analysis. Stress changes across various osteotomy directions and angles were compared. The findings indicate that a 30° extension and 30° abduction-opposition osteotomy significantly shift pressure distribution toward the volar side, which may reduce stress and enhance joint congruity.

有限元分析：第一掌骨最佳截骨角度治疗拇指腕掌骨关节炎的研究。

本研究探讨不同方向和角度的掌骨截骨术的影响。利用新鲜冷冻尸体的手CT-DICOM数据，建立三维模型并进行有限元分析。比较不同截骨方向和角度的应力变化。研究结果表明，30°外展和30°外展对向截骨术显著地将压力分布向掌侧转移，这可能会减少压力并增强关节一致性。
