目的探讨早期双侧小切口解剖复位、固定、关节腔内减压对青壮年股骨颈骨折术后愈合及股骨头无菌性坏死的影响。方法对本组35例GardenⅢ~Ⅳ型股骨颈骨折患者在24 h内行双侧小切口开放复位,用三枚空心钉行内固定术。结果本组35例均得到随诊,随诊时间平均40个月,其中1例股骨颈骨折合并不愈合及股骨头坏死,1例股骨头缺血性坏死,其他无不愈合及股骨头坏死。结论早期双侧小切口解剖复位,坚强内固定是提高股骨颈骨折愈合率、减少股骨头坏死的关键因素。
Objective To evaluate the effects of early bilateral micro-incision reduction,anatomic fixation and joint cavity decompression on the healing of young adults femoral neck fracture and femoral head ischemic necrosis after operation.Methods 35 cases of femoral neck fractures(type Garden Ⅲand Ⅳ) were treated by open reduction and internal fixation with 3 hollow screws through bilateral incisions within 24 hours from injury.Results All 35 cases were followed up,with an averaging period of 40 months.Except for one case resulted in bone nonunion and femoral head ischemic necrosis,and one femoral head ischemic necrosis,all other patients achieved excellent curative effects.Conclusions Early bilateral micro-incision anatomic reduction and strong internal fixation are keys to improving femoral neck fracture healing rate and decreasing femoral neck necrosis.
