Radial neck fractures are common injuries of the elbow in the pediatric patient. Surgical intervention is recommended for significant angulation and displacement or mechanical blocks to motion. Radial neck malunion is a rare complication and may result in altered joint mechanics and, if severe, joint incongruency. Dislocation of the radial head has yet to be reported in this population after radial neck malunion. Treatment for radial neck malunions with dislocation varies and can include radial head excision or radial neck osteotomy. Outcomes after radial neck osteotomy is limited to case reports and small cases series. We present a case report of pediatric patient with radial neck malunion and anterior radiocapitellar dislocation treated with joint realignment via opening wedge osteotomy. To our knowledge, this is the first report of a pediatric case with radial head dislocation secondary to neck malunion and the first described report using this technique.
桡骨颈骨折是儿科患者肘部的常见损伤。对于明显的成角、移位或运动机械性阻碍，建议进行手术干预。桡骨颈畸形愈合是一种罕见的并发症，可能导致关节力学改变，严重时可导致关节不匹配。在该人群中，尚未有桡骨颈畸形愈合后桡骨头脱位的报道。伴有脱位的桡骨颈畸形愈合的治疗方法各不相同，可包括桡骨头切除术或桡骨颈截骨术。桡骨颈截骨术的疗效仅限于病例报告和小病例系列。我们报告一例儿科患者，其桡骨颈畸形愈合并伴有桡骨小头前脱位，通过开放楔形截骨术进行关节复位治疗。据我们所知，这是首例因颈部畸形愈合继发桡骨头脱位的儿科病例报告，也是首例使用该技术的报道。
