Bold螺钉治疗内踝骨折的疗效分析

目的：对比Bold螺钉和普通空心螺钉内固定治疗单纯内踝骨折的疗效。方法：空心螺钉治疗单纯内踝撕脱骨折57例,分为A组Bold螺钉内固定治疗内踝骨折25例,B组使用普通空心螺钉内固定32例。结果：两组57例均获得随访,两组病例远期均能得到较坚强的固定和良好的功能恢复,但Bold螺钉组相对普通螺钉组愈合时间更快（P〈0.05）,下床活动时间更早（P〈0.05）,早期踝关节功能评分高（P〈0.05）,但六个月后没有明显差异。结论：Bold螺钉内固定有助于内踝骨折早期愈合和早期功能锻炼,是一种比较好的内固定材料,值得推广。

Bold screw for simple fracture of medial malleolus

Objective：To investigate and compare the therapeutic effect of the medial malleolus fracture by internal fixation using Bold screw and ordinary hollow screw.Methods：57 patients with medial malleolus fracture were divided into tow groups randomly.In group A,25 patients were operated by internal fixation with Bold screw.32 patients were operated by internal fixation with ordinary hollow screw in group B.Results：57 patients were followed up for 9~17 months,the two groups both received stationary fixation for fracture and satisfactory functional restoration in a long-term visit.Compared with group B,the group A got a quicker healing and the shorter time to leave the bed（P0.05）.All the patients were assessed with the American Orthopaedic Foot and Ankle Society（AOFAS） scoring system,the early score of the group A was higher than group B,but six months after the operation the score of the two groups had no differences.Conclusions：Internal fixation with the Bold screw conduce to the early healing and functional exercise.The bold screw is a better materi-al,which deserves to spread.
