摘要目的 评估PDLLA可吸收材料治疗掌骨骨折的临床疗效.方法 采用PDLLA可吸收棒治疗掌骨骨折25例(28处),克氏针内固定治疗31例(35处),比较两种手术的治疗效果.结果 经4～12个月随访,PDLLA可吸收棒髓内植入组25例(28处)骨折全部愈合,其中2例(2处)延迟愈合,骨折平均愈合时间4.6周.参照TAFS评分标准,优16例,良6例,差3例,优良率88%.克氏针内固定组3例(3处)出现畸形愈合,5例(5处)延迟愈合,1例(1处)骨不连,余骨折全部正常愈合.骨折平均愈合时间7.8周,优20例,良3例,差8例,优良率74.2%.两组问优良率有显著差异(P＜0.05).结论 PDLLA可吸收棒治疗掌骨骨折固定牢靠,不需要二次手术取出,其疗效明显优于克氏针组.

abstractsObjective To evaluate the clinical effects of PDLLA sticks in treatment of metacarpal fractures. Methods Twenty-five cases (28 metacarpal fractures)were performed with. Thirty-one cases( 35 metacarpal fractures) were treated with internal fixation with Kirschner wire, Comparison of curative effects of two operations were performed. Results Twenty five cases were followed up for 4 to 12 months,in PDLLA sticks group,mean healing time were 4. 6 weeks. All 25 cases fractures healed. Two cases suffered delayed union. According to the TAFS Scoring Sys-tem:sixteen cases were excellent ,6 cases were fine,3 cases were bad. The rate of excellant and good was 88% ,In Kirschner's group, the mean healing time were 7. 8 weeks. Three cases were malunion,5 cases suffered delayed union, 1 case was nonunion, the other fractures healed normally. Mean healing time were 7.8 weeks, Twenty cases were excellent, 3 cases were good, 8 cases were bad. The rate of excellent and good was 74. 2% ,There was significant difference in rate of excellent and good between two groups (P<0.05). Conclusion PDLLA sticks for the treatment of metacarpal fractures was available, do not need to remove the second operation,its effect is better than Kirschner wire group.
