拇腕掌关节是手关节中活动幅度最大的关节,可作伸、屈、收、展和旋转运动,是拇指稳定与活动的基石。但创伤等原因所致的拇腕掌关节缺损,将严重影响手的活动度,而且治疗相当困难。作者设计了吻合血管的第2跗跖部分关节移植重建拇腕掌关节,经临床应用3例,效果满意,实现其部分功能。为临床提供了一种新的治疗方法。为配合新术式的开展,本文对第2跗跖关节及其背侧血供进行较为详尽的解剖学观察,设计了多种血管蒂的第2跗跖部分关节移植重建拇腕掌关节的新术式。临床部分另文发表,现将有关的解剖学研究报告如下。 The wrist of the wrist is the joint with the largest range of motion in the hand and joint, which can be used for stretching, flexing, closing, exhibition and rotation. It is the cornerstone of the stability and activity of the thumb. However, due to trauma and other causes wrist joint palm defects, will seriously affect the hand activity, and the treatment is quite difficult. The authors designed the second tarsometatarsal joint which is anastomosed with the blood vessel to reconstruct the wrist of the wrist and meticulously. After the clinical application, the effect was satisfactory and some of its functions were achieved. Provides a new treatment for clinical. In order to cooperate with the development of new surgical technique, the anatomy of the second tarsometatarsal joint and its dorsal blood supply were studied in detail. The second tarsometatarsal graft was designed to reconstruct the metacarpal and medial palmar of the wrist. Surgery. Clinical part of the other published, now the relevant anatomical studies are as follows.
