    【Abstract】 Objective To appraise the clinical effect and applied value of the finger extender in treating unstable fracture of the distal radius which was operated unfold reduction and fixation. Methods The adoption of finger lengthening device can regulate,control and restore to the throne the regular method progressively,combine Kuntscher Nail partly which treat unstable fracture of the distal radius carry 102 cases.According to AO/ASIF dividing type:A3 type 61,C2 type 27,C3 type 14.Of treatment methods,simply unfold reduction and fixation were 76,using Kuntscher Nail to unfold reduction through skin were 26.Results 102 routine adopt this treat,3 were planted bone add plate regular to internal fixation. Off surplus 99 cases,57 cases were anatomical reduction,32 cases were functioncal reduction,11 cases close to functioncal reduction. The joint functionality is restored to the throne,73 cases were excellent,18 cases were fine,8 cases were badworse,no serious complication.Conclusion The finger extender can regulate,control and restore to the throne the regular to treat unstable fracture of the distal radius. The operation to be simple,stable fixation. The curative is satified,complication few methods. ......
