胫骨高位截骨Giebel刃形钢板与骑缝钉二种内固定方式的比较研究

目的：在应用胫骨高位截骨术(HTO)治疗膝关节骨性关节炎并膝内翻畸形的病例中，比较应用Giebel刃形钢板和骑缝钉二种不同的内固定方式的临床疗效。方法：15例行骑缝钉内固定术及石膏管型外固定，8例行Giebel刃行钢板内固定术。结果：所有病例均获得随访，两组术后6个月HSS评分相比并无统计学意义。在骑缝钉组1例出现断钉，2例丧失纠正角度。结论：Giebel刃形钢板与骑缝钉内固定均体现了满意的临床疗效，但Gieble刃形钢板术后能早期行功能锻炼，并发症更少．

Comparison of high tibial osteotomy with giebel blade plate or straddle nail internal fixation

Objective:To compare the clinical effect of high tibial osteotomy (HTO) with Giebel blade plate or straddle nail internal fixation for the treatment of osteoarthritis of knee with varum.Methods:Twenty-three cases of knee OA with genu varum were performed with HTO,in which 8 case by using Giebel blade plate and 15 cases by using straddle nail.Results:All patients were followed up.The genu varum defection were corrected obviously.Six months after operation,comparison between the two groups showed no significant differences in scoring on HSS standard.One case of nail rupture and two cases of loss of anticipant angle occurred in the group of straddle nail.Conclusion:HTO with either Giebel blade plate or straddle nail both apparently shows many advantages in the treatment of osteoarthritis of knee.HTO with Giebel blade plate can exercise more early and have much less complications than HTO with straddle nail internal fixation.
