Establishment and motion simulation of postoperative digital model with Scandinavian Total Ankle Replacement
目的 探讨STAR人工踝关节置换术后运动仿真的方法。 方法 应用Mimics 10.01、Geomgic studio 10.0、PRO/E 2.0软件模拟建立STAR人工踝关节置换术后数字模型，并利用PRO/E 4.0软件的机构设计和动画功能建立运动仿真。 结果 成功建立STAR人工踝关节置换术后数字模型屈伸、内收外展、内外翻运动仿真视频，形象了解术后STAR人工踝关节屈伸、内收外展、内外翻运动情况，直观了解STAR人工踝关节置换术后各方向运动理论活动度。 结论 建立STAR人工踝关节置换术后运动仿真有助于从人工关节术后理论活动度来预防手术的失败，提高手术的准确度。
Objective To investigate simulating motions of postoperative digital model with Scandinavian Total Ankle Replacement (STAR). Methods 3D postoperative digital model with STAR was established through the software of Mimics 10.01, Geomgic studio 10.0 and PRO/E 2.0, and then its motions were simulated through the software of PRO/E 4.0. Results Motion simulation videos of postoperative digital model with STAR were successfully established, including plantar flexion, dorsal flexion, adduction, abduction, inversion and eversion. All motions were iconically presented, while, postoperative theoretical range of all motions were obtained. Conclusions Motion simulation of postoperative digital model with STAR is beneficial to prevent operative failure and improve the operative accuracy by preoperatively presumption of the postoperative theoretical range of motion (ROM) of joint prosthesis.
