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 usingBold screw and ordinary hollow screw. Methods: 57 patients with medial malleolus fracture were divided into tow groups randomly. Ingroup A ,25 patients were operated by internal fixation with Bold screw. 32 patients were operated by internal fixation with ordinary hollowscrew in group B. Results: 57 patients were followed up for 9~17 months, the two groups both received stationary fixation for fractureand satisfactory functional restoration in a long-term visit.Compared with group B, the group A got a quicker healing and the shorter timeto leave the bed(P<0.05). 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 material,which deserves to spread.
