Few cases of humeral medial epicondyle nonunion develop to symptomatic condition. We report a pediatric case of distally displaced nonunion. At first, the palliative repair surgery was chosen due to irreduciblity of the epicondyle fragment at 10 years old. After 2 years and 3 months wait for maturation of ossification at the trochlea, the definitive surgery consisting of epicondylectomy and ligament reconstruction was performed. This is the first pediatric case of humeral medial epicondyle nonunion with an unossified trochlea which needed a two-staged surgery. We highlight the surgical plan aimed at anatomical ligament reconstruction focusing an isometric point of MCL.
肱骨内上髁骨不连发展为有症状情况的病例很少。我们报告一例儿童远侧移位性骨不连病例。起初，由于10岁时内上髁骨折块无法复位，选择了姑息性修复手术。在等待滑车处骨化成熟2年零3个月后，进行了包括内上髁切除术和韧带重建的确定性手术。这是首例患有未骨化滑车的儿童肱骨内上髁骨不连且需要分两期手术的病例。我们着重介绍了旨在进行解剖学韧带重建的手术方案，重点关注内侧副韧带的等长点。
