The costo-osteochondral autograft, vascularized medial femoral trochlear osteochondral autograft, and proximal hamate autograft have been used for the reconstruction of unsalvageable proximal pole scaphoid nonunions. Our hypothesis is that there is no difference in carpal kinematics after the proximal pole of the scaphoid is reconstructed with these three graft options. Wireless sensors were mounted to the carpus that was loaded through cyclical motion. Each specimen was tested under a series of the three reconstructed conditions and their kinematics compared. No significant differences were found in scapholunate and lunocapitate joint motion during wrist flexion-extension and wrist radioulnar deviation between the three reconstructed conditions ( > 0.05). There are minimal differences in carpal kinematics when comparing reconstruction of the proximal pole of the scaphoid with the costoosteochondral, medial femoral trochlear, and proximal hamate grafts.
肋软骨自体移植、带血管的股骨内侧滑车软骨骨自体移植和钩骨近端自体移植已被用于无法挽救的舟骨近端骨不连的重建。我们的假设是，用这三种移植方式重建舟骨近端后，腕关节运动学没有差异。无线传感器安装在通过循环运动加载的腕骨上。每个标本在三种重建条件下进行测试，并比较其运动学。在三种重建条件下，腕关节屈伸和桡尺偏斜时，舟月关节和月头关节运动没有显著差异（>0.05）。比较用肋软骨、股骨内侧滑车和钩骨近端移植重建舟骨近端时，腕关节运动学差异极小。
