目的探讨髋臼周围旋转截骨治疗大龄儿童先天性髋关节脱位的效果。方法选择先天性髋关节脱位的大龄儿童9例,使用髋臼周围旋转截骨手术治疗的方法对患儿进行治疗,观察其治疗效果。结果治疗后所有患儿股骨头和髋臼形态均恢复正常,截骨和植入处均已愈合,且骨密度与周围骨组织基本一致,并无坏死现象发生;随访1年后,无患儿存在髋关节疼痛现象,8例患儿髋关节活动基本恢复正常,无跛行现象发生,1例患儿存在髋关节活动部分受限,但无坏死现象发生。结论髋臼周围旋转截骨术治疗大龄患儿髋关节脱位符合人体髋关节的生理解剖特点,能够有效稳定地复位患儿的关节组织,并为其术后康复奠定基础,是一种值得临床上进行推广应用的治疗方法。 Objective To investigate the effect of rotational osteotomy around the acetabulum in the treatment of congenital dislocation of the hip in older children. Methods Nine elderly children with congenital dislocation of the hip were selected and treated by rotational osteotomy around the acetabulum. The therapeutic effect was observed. Results After treatment, the shape of femoral head and acetabulum of all children returned to normal, the osteotomy and implantation sites were healed, and the bone mineral density was almost the same as that of the surrounding bone tissue without necrosis. One year after follow-up, Hip joint pain was present in 8 children. The activities of hip joint returned to normal in 8 children without claudication. One patient had limited hip mobility but no necrosis. Conclusion Rotating osteotomy around the acetabulum in elderly patients with hip dislocation is in line with the physiological anatomical characteristics of human hip joint. It can effectively and steadily restore the joint tissues of children and lay the foundation for its postoperative rehabilitation. To promote the use of treatment methods.
