A 2.5-year-old male child presented to the clinic for evaluation of left wrist popping. Ten months earlier, he sustained a closed left both-bone forearm fracture (BBFF) treated with reduction and casting. His clinical course was complicated by redisplacement requiring secondary manipulation and casting before osseous union. His parents reported wrist popping with active motion in the setting of a 20° apex volar malunion of the midshaft radius. He has been treated with observation and monitoring of deformity remodeling.
Distal radioulnar joint instability is a potential complication of malunited BBFF, even in a pediatric population. Residual deformity, especially in the radius, should prompt clinical follow-ups after osseous union to assess functional recovery and deformity remodeling.
一名 2.5 岁男童因左腕关节弹响就诊。10 个月前，他因左尺桡骨双骨折（BBFF）接受了复位和石膏固定治疗。在骨折愈合前，他的病情出现了再移位，需要进行二次手法复位和石膏固定。他的父母报告说，在中轴半径 20°掌侧成角畸形愈合的情况下，他的手腕在主动活动时会出现弹响。他一直接受观察和畸形矫正监测。
即使在儿童人群中，桡尺远侧关节不稳定也是畸形愈合的 BBFF 的潜在并发症。残余畸形，特别是桡骨，应在骨愈合后进行临床随访，以评估功能恢复和畸形矫正情况。
