病灶清除植骨联合DHS内固定治疗股骨近端囊肿

Treatment of Proximal Femur Cyst by Curetting and Implanting Bone Combined with DHS Fixation

目的：探讨病灶清除植骨联合动力髋螺钉（DHS）内固定术治疗股骨近端囊肿的临床疗效及意义。方法：自2006年3月至2012年6月共有17例股骨近端囊肿患者在我院接受治疗并有完整随访,全部患者均应用病灶清除植骨联合DHS内固定术手术治疗。结果：平均随访时间18个月（14-60个月）,病灶植骨处平均愈合时间7个月（6-8个月）。平均手术时间182分钟（90分钟~282分钟）,术中平均出血量340 mL（100~700 mL）。切口全部一期愈合,术后病灶处均达到骨性愈合,骨密度均匀,17例均未出现骨囊肿复发及内固定断裂,未发生股骨头坏死及股骨近端骨折,按Harris髋关节功能评分标准,优良率为100%。结论：病灶清除植骨术联合DHS内固定治疗股骨近端囊肿操作简单,术中出血少,并发症少,疗效确切,是治疗股骨近端骨囊肿,降低其复发率和预防病理性骨折的一种有效方法。

Objective： To study the clinical effect and significance of curetting and implanting bone combined with Dynamic hip screw （DHS） fixation on the treatment of the cyst near femoral head. Methods： 17 patients with proximal femur cyst who were treated in our hospital from March 2006 to June 2012 were selected and followed-up. Results： All the patients were followed up for 18 months （range,14-60 months）. The average healing time of bone lesions was 7 months （6-8 months）. The average time for operation was 182 minutes（90-282 minutes）, the average blood loss was 340 mL（100 -700 mL）; Lesions of have 17 patients got well after operation without any recurrency, or femoral head avascular necrosis. 100% fineness was reached according the Harris Hip Joint Function Scale. Conclusions： Curetting and implanting bone combined with DHS fixation of proximal femur cyst is a new effective method, with simply procedure, less complications and lower recurrent rate.
