摘要
目的探讨经Watson-Jones入路采用动力髋螺钉(dynamic hip screw,DHS)内固定联合病灶扩大刮除治疗股骨近端良性肿瘤及肿瘤样病变的疗效。方法 2012年3月—2016年12月,采用经Watson-Jones入路DHS内固定联合病灶扩大刮除治疗股骨近端良性肿瘤及肿瘤样病变患者20例(21处)。其中男13例,女7例;年龄11~51岁,平均27.8岁。病变累及单侧股骨19例,双侧1例。病理类型:纤维结构不良11例,骨囊肿2例,动脉瘤样骨囊肿2例,良性纤维组织细胞瘤2例,骨巨细胞瘤2例,软骨母细胞瘤1例。Enneking外科分期:除3例病理性骨折为S2期外,其余均为S1期。术前均无股骨近端内、外翻畸形。记录手术时间、术中出血量以及患者术后完全负重时间。随访摄X线片及CT,了解植骨及DHS情况;采用疼痛视觉模拟评分(VAS)评价疼痛缓解情况,国际骨与软组织肿瘤协会(MSTS)评分标准评估下肢功能。结果手术时间110~265 min,平均177.1 min;术中出血量200~2 300 mL,平均828.6 mL。术后发生切口浅表感染1例,深部感染1例,存在患髋不适感1例。患者均获随访,随访时间为6~63个月,平均27.4个月。2例骨巨细胞瘤患者术后2 d达完全负重;其余患者术后2~13周完全负重,平均7.2周。末次随访时,VAS评分为(0.19±0.51)分,与术前的(3.52±2.62)分比较,差异有统计学意义(t=5.565,P=0.000)。患者髋关节功能均恢复良好,末次随访时MSTS评分为(29.62±0.97)分,与术前的(23.71±8.77)分比较,差异有统计学意义(t=–3.020,P=0.007)。影像学检查示植骨均融合,融合时间为5~12个月,平均8.2个月。术后无病理性骨折、内固定物松动和断裂、股骨头缺血坏死以及关节脱位发生。随访期间无肿瘤复发、转移。结论经Watson-Jones入路充分暴露后行病灶刮除修复病损、DHS内固定治疗股骨近端良性肿瘤及肿瘤样病变安全、有效。
Objective To explore the effectiveness of dynamic hip screw（DHS） and intralesional curettage via Watson-Jones approach in treatment of benign bone lesions of the proximal femur. Methods Between March 2012 and December 2016, 20 patients（21 lesions） with benign bone tumors or tumor like conditions of proximal femurs were treated with DHS and intralesional curettage via Watson-Jones approach. Their average age was 27.8 years（range, 11-51 years）, including 13 males and 7 females. The pathological diagnosis were fibrous dysplasia in 11 cases, simple bone cyst in 2 cases, aneurysmal bone cyst in 2 cases, benign fibrous histocytoma in 2 cases, giant cell tumor in 2 cases, and chondroblastoma in 1 case, including 3 pathological fractures. According to the Enneking staging system, 18 patients were in stage S1, 3 patients with pathological fractures in stage S2. There was no varus deformity or valgus deformity. The operation time, intraoperative blood loss, and time of full weight-bearing were recorded. X-ray film and CT were used to observe the bone graft fusion and location of DHS. Complications were recorded. Visual analogue scale（VAS） and Musculoskeletal Tumor Society（MSTS） scoring were used to evaluate function of lower limbs. Results The average operation time was 177.1 minutes（range, 110-265 minutes）. The average intraoperative blood loss was 828.6 mL（range, 200-2 300 mL）. There was superficial incision infection in 1 case, deep incision infection in 1 case, and hip discomfort in 1 case, respectively. All patients were followed up 6-63 months（mean, 27.4 months）. The time of full weight-bearing was 2 days in 2 patients with giant cell tumor and 2 to 13 weeks with an average of 7.2 weeks in the other patients. At last follow-up, VAS and MSTS were 0.19±0.51 and 29.62±0.97 respectively, showing significant differences when compared with the values before operation（3.52±2.62 and 23.71±8.77）（t=5.565, P=0.000; t=–3.020, P=0.007）. X-ray film showed the all bone grafts fusion wit
