BACKGROUND
Dysplasia epiphysealis hemimelica (DEH), or Trevor's disease, is a developmental disorder of the pediatric skeleton characterized by asymmetric osteochondral overgrowth.
METHODS
We present the case of a five year old boy with a two year history of right knee pain and evidence of DEH on imaging who underwent initial arthroscopic resection of his lesion with subsequent recurrence. The patient then underwent osteochondral allograft revision surgery and was asymptomatic at two year follow-up with a congruent joint surface.
RESULTS
To our knowledge, this is the first reported case of a DEH lesion treated with osteochondral allograft and also the youngest reported case of osteochondral allograft placement in the literature.
CONCLUSIONS
Osteochondral allograft may be a viable option in DEH and other deformities of the pediatric knee.
LEVEL OF EVIDENCE
Level V.
背景
骨骺发育异常半侧肥大（DEH），即特沃里氏病，是一种小儿骨骼发育障碍，其特征为不对称的骨软骨过度生长。
方法
我们报告了一例5岁男孩，有两年右膝疼痛病史，影像学检查显示为DEH，最初接受了关节镜下病变切除术，但随后复发。该患者随后接受了骨软骨异体移植翻修手术，在两年随访时关节面一致且无症状。
结果
据我们所知，这是首例报道用骨软骨异体移植治疗DEH病变的病例，也是文献中报道的接受骨软骨异体移植最年轻的病例。
结论
骨软骨异体移植可能是治疗DEH及小儿膝关节其他畸形的一种可行选择。
证据级别
V级。
