High complication rates and surgical revision rates following Aptis implant placement have been reported in the literature. This study evaluates the performance of the Aptis implant of twelve patients using four-dimensional kinematic analysis. The (mean) follow-up was 58 months. Wrist motion, grip strength, and kinematic analysis of both arms were used to investigate possible causes of the reported complications. In nine cases (75%), the proximal to distal translation of the distal radius along the ulnar axis in the affected forearm was too little or absent. Significant correlations were found between postoperative extension and translation of the distal radius along the ulnar axis and between the radial deviation and combined error. The four-dimensional kinematic analysis suggests that the current design of the implant could lead to limited restoration of the position of the forearm rotation axis and the translation of the radius along the ulnar axis.
文献报道了Aptis植入物置入后较高的并发症发生率和手术翻修率。本研究采用四维运动学分析评估了12例患者的Aptis植入物的性能。平均随访时间为58个月。使用双侧手臂的腕部运动、握力和运动学分析来调查所报道并发症的可能原因。在9例（75%）病例中，患侧前臂桡骨远端沿尺骨轴的近端至远端平移过小或不存在。发现术后桡骨远端沿尺骨轴的伸展和平移之间以及桡偏和综合误差之间存在显著相关性。四维运动学分析表明，植入物的当前设计可能导致前臂旋转轴位置和桡骨沿尺骨轴平移的恢复有限。
