关节镜治疗婴幼儿发育性髋关节脱位

The efficacy of arthroscopic surgical treatment for infant with developmental dislocation of the hip

目的：探讨关节镜治疗婴幼儿发育性髋关节脱位（DDH）的临床疗效。方法对13例DDH患儿（17髋）采用关节镜治疗。结果患儿均获得随访，时间3-7（5．3±2．1）年。至末次随访，患儿均获得正常步态及髋关节活动度，无一例患儿出现股骨头坏死。髋臼指数由术前32．9°-51．8°（39．4°±11．3°）改善至末次随访时的19．8°-33．1°（24．8°±6．5°）（P〈0．001）。除1例（1髋）继发DDH外，其他患儿均获得股骨头与髋臼同心圆复位，恢复Shenton线连续性。结论采用关节镜治疗婴幼儿DDH临床疗效满意，具有创伤小、并发症发生率低等优点。

Objective To investigate clinical results of arthroscopic surgical treatment for developmental dislocation of the hip （DDH） in the infant. Methods Thirteen patients （17 hips） with DDH underwent arthroscopic surgical treatment. Results All of 13 patients were followed up for 3-7 （5. 3 ± 2. 1） years. At the final follow-up, all pa-tients had normal gait and full range of motion, without femoral head necrosis. The acetabular index improved from 32. 9°-51. 8° （39. 4 ± 11. 3）° preoperatively to 19. 8°-33. 1°（24. 8 ± 6. 5）° postoperatively（P〈0. 001）. Except for 1 hip secondary DDH,the other children got femoral head and acetabulum concentric circles reset,and restored Shenton′s line continuity. Conclusions The arthroscopic surgical treatment of infant with DDH can achieve satisfac-tory clinical outcomes, and has the advantage of less trauma and low rate of complication.
