The purpose of this study was to quantify changes in temporal-spatial parameters and multisegmental foot/ankle kinematics in a group of patients with hallux rigidus following cheilectomy. Three-dimensional motion analysis was conducted using a 15-camera Vicon Motion Analysis System on a population of 19 patients who underwent cheilectomy for hallux rigidus. Data were analyzed using the four-segment Milwaukee Foot Model. Preoperative and postoperative tests were compared using paired parametric methods. Results showed significant improvements in walking speed, cadence, stride length, and stance/swing ratio from preoperative to postoperative state. Altered hallux and forefoot positions preoperatively showed shifts towards normal after cheilectomy. Although clinical improvements in pain and passive range of motion were statistically significant, similar improvements in range of motion were not demonstrated during ambulatory testing. The results of this study provide insight into ambulatory improvements following cheilectomy, and suggest further study of the rehabilitation process to improve the recovery of functional range of motion.
本研究的目的是量化一组拇僵硬症患者在进行关节切除术之后时空参数和多节段足/踝关节运动学的变化。使用15台摄像机的Vicon运动分析系统，对19例因拇僵硬症接受关节切除术的患者进行三维运动分析。采用四段式密尔沃基足部模型分析数据。术前和术后测试采用配对参数方法进行比较。结果显示，从术前到术后状态，步行速度、步频、步幅和站立/摆动比均有显著改善。术前拇趾和前足位置的改变在关节切除术后显示向正常方向转变。虽然疼痛和被动活动范围的临床改善具有统计学意义，但在动态测试中未显示出类似的活动范围改善。本研究结果为关节切除术后的动态改善提供了见解，并建议进一步研究康复过程以改善功能活动范围的恢复。
