开发了三维 (3D) CT 技术来分析体内节段腕骨运动学。获取前臂远端、腕骨和近端掌骨的横向 CT 数据，并在不同手腕位置进行 3D 重建。对两组 20 名无症状志愿者进行了腕骨运动学分析，一组处于中立位、屈曲和伸展（45 度），另一组处于中立位、桡骨（15 度）和尺骨偏差（30 度）。定性分析包括腕骨解剖结构的 3D 研究，以及所获得的不同数据集之间腕骨位置的比较。使用刚体和有限螺旋轴概念量化腕骨运动。结果虽然原则上与之前的发现一致，但显示出腕骨运动的重要个体差异。对 25 名患有各种腕部疾病的患者进行了一系列临床应用。受伤手腕与无症状异侧手腕之间没有显着差异，但无症状志愿者与患者受伤手腕和异侧手腕之间存在显着差异。特别是，我们的患者组的双侧舟状骨运动发生改变，表明存在易患某些腕骨病变的解剖学和/或运动学因素。这一假设需要得到证实和完善。
A three-dimensional (3D) CT technique was developed to analyze in vivo segmental carpal kinematics. Transverse CT data of the distal forearm, carpals and proximal metacarpals was acquired and 3D reconstructed in various wrist positions. Carpal kinematics were analyzed in two groups of 20 asymptomatic volunteers, one group in neutral position, flexion and extension (45 degrees), and the other group in neutral position, radial (15 degrees) and ulnar deviation (30 degrees). Qualitative analysis included the 3D study of carpal anatomy, and comparison of carpal bone position between the different sets of data obtained. Carpal bone motion was quantified using rigid body and finite helical axis concepts. The results, although agreeing in principle with previous findings, showed important individual variations in carpal bone motion. Clinical applications were conducted in a series of 25 patients with various wrist disorders. There was no significant difference between the injured wrist and the heterolateral, asymptomatic wrist, but there was a significant difference between asymptomatic volunteers and both the injured wrist and heterolateral wrist of patients. in particular, scaphoid motion was altered bilaterally in our patient group, suggesting the existence of anatomic and/or kinematic factors predisposing to certain carpal pathologies. This hypothesis needs to be confirmed and refined.
