摘　　要：目的介绍掌指关节活动型外固定架在治疗掌骨基底骨折中的手术方法及经验体会．方法根据外固定架针杆夹的形状，于骨折近远端分别旋入4枚骨牵引针，闭合复位需根据骨折移位方向进行对抗牵引，通过调节万向关节矫正成角及旋转畸形，撑开连接杆矫正短编畸形．早期行邻近关节功能锻炼，固定4-6周后拆除外固定架。结果61例掌骨基底骨折，其中第1掌骨基底骨折25例，第4掌骨基底骨折17例，第5掌骨基底骨折19例，随访半年58例，关节功能恢复良好，各指活动无受限．结论掌指关节活动型外固定架以微创方式应用于掌骨基底骨折，操作简单，精确固定，肢体功能恢复满意．Objective To introduce the surgical methods and experiences in the treatment of fractures of the metacarpal base by using external fixator of metacarpophalangeal joint activity type. Methods Four skeletal traction pins were screwed into the proximal and distal end of fracture, according to the shape of needle bar folder of external fixator. Countertraction was carried out according to the direction of fracture displacement in the closed reduction. The correction of angular and rotational deformity depended on adjusting universal joints.Adjusting the short and rotatory deformity by distraction connection rod. Early functional exercise was used to near joints. Removal of external fixator after 4 to 6 weeks. Results In 61 cases of metacarpal base fractures, of which the first metacarpal base fracture in 25 cases, the fourth metacarpal base fracture in 17 cases, the fifth metacarpal base fractures in 19 cases. 58 cases were followed up for 6 months, ,tll of them had satisfactory recovery of joint function. None of the finger movement was limited. Conclusion External fixator of metacarpophalangeal joint activity type was minimally invasive, simple, accurate and satisfactory in the treatment of fractures of the metacarpal base.
