摘  要:目的评价Steel骨盆三联截骨联合手术治疗大龄儿童发育性髋关节脱位的疗效。方法自2006年至2012年采用Steel骨盆三联截骨术联合其他手术治疗大龄儿童发育性髋关节脱位53例(67髋),其中50例(64髋)术中行股骨近端截骨,18例(24髋)同时行股骨近端内翻截骨。手术时年龄7~16.5岁,平均10.2岁,其中男16例,女37例,双侧14例,单侧39例。按照Tonnis分级标准:I级18髋,Ⅱ级31髋,Ⅲ级15髋,Ⅳ级3髋。所获得数据应用SpssStatistics18.0统计软件进行统计分析。结果所有患儿随访1.5~6.5年,平均3.3年。术前X线片显示:CEA平均-1.8°(-45°~25°),AI平均33.0°(20°~50°),AHI平均47.5%(0%~69%)。最后随访X线片显示:CEA平均为38.5°(25°~50°),较术前增大40.3°;AI平均为16.8°(5°~25°),较术前减小16.2°;AHI平均为88.2%(70%~100%),较术前增大40.7%;最后随访的AI、CEA及AHI均较术前有明显改善,差异有统计学意义(P〈0.01)。参照Mekay评价标准进行评定:优36髋,良23髋,可6髋,差2髋,优良率88.1%。最后随访时3髋新发股骨头缺血性坏死,根据Kalamchi and MacEwen评价标准进行评定:Ⅱ级2髋,Ⅲ级1髋。结论Steel骨盆三联截骨联合手术治疗大龄儿童发育性髋关节脱位的疗效良好。Objective To evaluate the outcomes of steel triple pelvic osteotomy for developmental dysplasia of the hip (DDH) in older children. Methods From 2006 to 2012, 53 DDH children (67 hips) underwent steel triple pelvic osteotomy. Among them, 50 children (64 hips) underwent proximal femoral osteotomy while another 18 (24 hips) had concurrent varus osteotomy. There were 16 males and 37 females with a mean operative age of 10. 2 (7-16. 5) years. And the involvement was bilateral (n = 14) and unilateral (n = 39). Based on the Tonnis classification, 18 hips were grade I , 31 grade Ⅱ , 15 grade Ⅲ and 3 grade IV. Statistical analysis was performed with Statistical Product & Service Solutions Statistics 18. 0. Results The mean follow-up period was 3. 3 (1.5-6. 5) years. Plain radiography showed that the values of center-edge angle (CEA), acetabular index (AI) and acetabular head index (AHI) were - 1.8° ( - 45°-25°), 33.0° (20°-50°) and 47. 5% (0%-69%) at pre-operation and 38. 5° (25°-50°), 16. 8° (5°-25°) and 88. 2% (70% 100%) respectively during the latest follow-up. AI, CEA and AHI all improved. And the differences were statistically significant (P〈0. 01). According to the Mckay classification, the outcomes were excellent (36 hips), good (23 hips), fair (6 hips) and poor (2 hips). And the percentage of excellent and good hips was 88. 1 %. According to the Kalamchi & MacEwen classification, hip avascular necrosis of grade Ⅱ (n = 2) and Ⅲ (n = 1 ) developed at the last follow-up. Conclusions The outcome of steel triple pelvic osteotomy is satisfactory for DDH in older children.
