摘要
目的 总结 6 4例各型股骨粗隆间骨折应用动力髋螺钉 (dynam ic hip screw,DHS)内固定的经验和提高疗效的措施。方法 全部采用 AO分型。均采用 135°DHS内固定。术前、术中和术后采取综合措施 ,确保复位和内固定精度 ,防止并发症 ,促进骨折顺利愈合。结果 全部 6 4例 8～ 12周临床愈合。 5 6例 A1、A2型愈合后无并发症。 8例 A3型中 1例发生轻度髋内翻。 6 4例无死亡。手术疗效评定 :优 35例 (5 4.7% ) ,良 2 8例 (43.8% ) ,并发症1例 (1.5 % )。结论 DHS内固定是治疗股骨粗隆间骨折的理想方法 ,失败率低。术前、术中和术后的综合措施对改善疗效起重要作用。
Objective To summarize the experiences of fixation with dynamic hip screw (DHS) and measures used to improve the surgical results of intertrochanteric fracture.Methods 135° DHS were fixed onto all patients with stable or unstable intertrochanteric fracture based on AO classification,pre ,intra and postoperative comprehensive measures were utilized so as to ensure the accuracy of intraoperaive reduction and fixation,avoidance of complication and bring about bone union smoothly.Results All patients were achieved solid bone union at 8～12 weeks,in 56 patients with 31 A1 and 31 A2 type the fractures achieved solid bone union without complications.While one patient remained a slight varus malunion in 8 patients suffered from 31 A3 type fractures.No operative mortaliy and split in DHS device or dislodgement of screw,no wound infection and rigidity of knee joint or badsore.Surgical rsults were excellent in 35(54.7%),good in 28 (43.8%) and complication in one (1.5%).Conclusions Fixation with DHS in patients with intertrochantersic fracture is considered to be more ideal procedure and has the lowest failure rate (1.5%).Pre and intra and post operative comprehensive measures played an important role in impoving the surgical rsults.
