BACKGROUND This study aimed to explore the effect of the treatment through autologous fibula graft and hollow needle fixation to treat femoral head cutting after dynamic hip screw (DHS) fixation. METHODS A total of 41 patients were admitted to the department of orthopedic trauma and received DHS fixation. Preoperative and postoperative harris score of hip function, limb shortening length and collodiaphysial angle between operation group (n = 11) and non-operation group (n = 13) were compared. RESULTS There was no difference between the two groups before surgery (P > 0.05). There was a difference between the preoperative and postoperative in the operation group (P < 0.05). The excellent and good rate of the hip function score in patients 6 months after the operation was 55.6%. In the operation group, the hip function score increased after surgery (P < 0.001). Except for two groups of patients before operation, there was a difference in the limb shortening length and collodiaphysial angle between the operation group and non-operation group in other time points after surgery (P < 0.001). CONCLUSION The application of the autogenous fibula graft and hollow nail fixation was effective in treating femoral head cutting after DHS fixation, and patients' subjective evaluation and objective indicators' outcomes of follow up were satisfactory, which was worthy of clinical application.

DHS固定后自体腓骨移植和空心螺钉固定至头颅切开术：一项回顾性研究。

背景技术本研究旨在探讨通过自体腓骨移植和空心针固定治疗动态髋螺钉（DHS）固定后股骨头切开术的效果。方法共有41例患者被纳入整形外科创伤科并接受DHS固定。比较手术组（n = 11）和非手术组（n = 13）的髋关节功能，术前和术后髋关节harris评分，肢体缩短长度和骨dia端角度。结果两组术前无差异（P> 0.05）。手术组的术前与术后有差异（P <0.05）。术后6个月患者髋部功能评分优良率55.6％。在操作组中 术后髋关节功能评分增加（P <0.001）。除两组患者术前外，其他时间点手术组与非手术组的肢体缩短长度和骨dia端角均存在差异（P <0.001）。结论自体腓骨移植及空心钉内固定治疗DHS固定后股骨头切开术效果良好，患者的主观评价和客观指标随访均令人满意，值得临床推广。
