异体骨移植治疗小儿先天性髋关节发育不良

背景：骨盆截骨治疗先天性髋关节发育不良需取自体髂骨植入截骨间隙,对年龄较小的患儿取髂骨植骨存在一定的局限性。目的：观察同种异体骨移植治疗小儿先天性髋关节发育不良的效果。方法：对年龄1.5～3.0岁先天性完全性髋关节脱位36例患儿截骨后采用同种异体骨块移植治疗,影像学评价髋关节脱位治疗效果。结果与结论：治疗后随访1.0~2.5年,未出现伤口渗液,疼痛,无排斥反应,无同种异体骨骨块移位及吸收病例。影像学评价髋关节脱位疗效显示,优良38髋（90%）,中3髋（7%）,差1髋（3%）。表明在小儿先天性髋关节发育不良骨盆截骨治疗中,选用同种异体骨移植,随访效果满意。

Allogenic bone transplantation for pediatric developmental dysplasia of the hip

BACKGROUND：Pelvic osteotomy in the treatment of children with developmental dysplasia of the hip（DDH） has been widely used,but for younger children there are some limitations in the traditional treatment methods,which requires the implantation of autologous iliac in the osteotomy gap.OBJECTIVE：To discuss the efficacy of allogenic bone transplantation in the treatment of pediatric DDH.METHODS：A retrospective study was carried out in 36 DDH patients aged 1.5-3.0 years undergoing allogenic bone transplantation.The treatment of hip dislocation was evaluated by imaging.RESULTS AND CONCLUSION：The follow-up of 1.0-2.5 years after treatment showed that there was no incision drainage;none of patients had slight pain in the hip,no rejection,no allograft bone displacement and absorption.Imaging evaluation for the efficacy of hip dislocation showed that 38 hips were excellent and good（90%）,three hips were fair（7%） and one hip was poor（3%） after treatment.The follow-up result of allogenic bone transplantation for pediatric DDH was satisfied.
