目的丰富髋关节发育不良及大龄发育性髋关节半脱位的治疗手段。方法采用关节囊外的沟槽植骨,外板夹卡,垛状髋臼扩大术对发育性髋关节发育不良,大龄髋关节半脱位的患儿15例(20个髋,5例为双髋)进行治疗。采用先天性髋脱位疗效评定标准,根据患儿主观感觉,临床检查及X线摄片检查评定为依据进行评分。用Charnley评分标准及Harris评分标准对照。结果垛状髋臼扩大术采用交叉网状外板夹卡植骨方式,可大大改善髋臼包容,20髋中最大改善度由65％增大到85％,最小改善度由75％到90％。髋臼覆盖率超过85％,髋臼指数小于25°。结论垛状髋臼扩大术是一种安全、复合解剖结构而设计的一种外板夹卡交叉网状植骨造盖手术,有效扩大髋臼包容面积更加稳定。
Purpose To enrich the treatment of dysplasia of hip and advanced development of subluxated hip. Methods 15 cases (20 hips, 5 hips) with hip bone dysplasia and hip hip subluxation were treated with groove grafting outside the joint capsule, external plate clamp and popliteal acetabular enlargement. ) For treatment. Using congenital hip dislocation efficacy evaluation criteria, based on subjective feelings of children, clinical examination and X-ray examination to assess the basis for grading. Control with Charnley score and Harris score. Results Stacked acetabulum enlargement using cross-shaped mesh plate clamping bone graft method can greatly improve acetabular tolerance, 20 hip maximum improvement from 65% to 85%, the minimum improvement from 75% to 90% . Acetabular coverage of more than 85%, acetabular index less than 25 °. Conclusion Stacked acetabulum enlargement is a kind of safe, composite anatomical structure designed by a cross-shaped plate graft carding surgery, effectively expanding the acetabular accommodating area more stable.
