Abstract：
UNASSIGNED: This article\'s purpose was to analyze clinical results obtained with thumb carpometacarpal (CMC) arthroscopic hemitrapeziectomy with temporary suspension with a Kirschner wire (K-wire).
UNASSIGNED: Seventy thumb CMC arthroscopic hemitrapeziectomies with a mean age of 59 and 18 months of follow-up were performed in our center during a 13-year period. All of them followed the same protocol. Surgical technique is described.
UNASSIGNED: All patients were arthroscopically classified as Badia\'s III stage. No tendon interposition was used, and a K-wire was temporarily implanted for 5.1 weeks. Mean postsurgical Visual Analogue Scale of 1.6, Kapandji Opposition Score of 8.1, grip strength of 42.2 lbs, lateral pinch of 9.5 lbs, tip-to-tip pinch of 4.2 lbs and tripod pinch of 7.8 lbs were measured. All previous active workers resumed their previous job.
UNASSIGNED: We conclude that thumb CMC arthroscopic hemitrapeziectomy with temporary suspension with K-wire reaches good results in terms of pain reduction, strength, and functionality, without the necessity of an internal brace which increases risks of a second metacarpal fracture.

摘要：
■本文的目的是分析拇指腕掌（CMC）关节镜下半叶切除术并使用克氏针（K-wire）临时悬吊术获得的临床结果。
■在我们的中心进行了70例拇指CMC关节镜下半叶肌切除术，平均年龄为59岁，随访18个月。他们都遵循相同的协议。描述了手术技术。
■所有患者均被关节镜分类为BadiaIII期。没有使用肌腱插入术，暂时植入K线5.1周。术后平均视觉模拟评分为1.6，Kapandji反对评分为8.1，握力为42.2磅，横向捏合9.5磅，测得的尖端到尖端的夹点为4.2磅，三脚架的夹点为7.8磅。所有以前的现役工人都恢复了以前的工作。
■我们得出的结论是，拇指CMC关节镜下半叶切除术与K线临时悬吊在减轻疼痛方面取得了良好的效果，力量,和功能，不需要增加第二掌骨骨折风险的内部支具。
