术后轻量牵引对股骨颈骨折股骨头坏死的预防效果观察

目的观察股骨颈骨折术后应用轻量牵引对股骨头坏死的预防效果。方法对48例股骨颈骨折应用空心螺钉治疗,并在术后进行轻量骨牵引。结果随访36-48个月,2例延期愈合,3例股骨头晚期塌陷,1例股骨头早期坏死。结论在早期行空心钉固定手术,良好的复位的基础上,术后通过一定时期的轻量骨牵引等综合措施,可以有效减少股骨头坏死及骨折不愈合的发生。

Prevention of Osteonecrosis of Femoral Head Caused by Transcervical Fracture by Slight Postoperative Skeletal Traction

Objective To observe the preventive effectiveness of slight postoperative skeletal traction for osteonecrosis of femoral head caused by transcervical fracture.Methods Forty-eight patients with transcervical fracture were treated with hollow bolt combined with slight postoperative skeletal traction.Results During a follow-up period of 36-48 months,2 had delayed healing,3 had late subsidence of femoral head,and 1 had early osteonecrosis of femoral head.Conclusion On the basis of fixation with hollow bolt and proper diaplasis in the early stage,slight postoperative skeletal traction for a certain period can decrease the occurrence of osteonecrosis of femoral head and failure of healing.
