儿童桡骨远端骨骺损伤致尺骨撞击征一例报告

To investigate the clinical characteristics of ulnocarpal impingement syndrome in children induced by distal radial epiphyseal injuries in long term. A retrospective analysis of one child with distal radial epiphyseal injuries combined with dislocations was performed. The child had a sore wrist at 6 years after manual reduction. The diagnosis of ulnar impingement was conifrmed according to the patient history, symptoms, physical signs and radiological examinations of bilateral wrist joints. Ulnar impingement would occur in children with distal radial epiphyseal injuries in long term. Repeated manual reduction should be avoided in children with distal radial epiphyseal injuries, in order to minimize secondary epiphyseal injuries and reduce the risk of early epiphyseal closure. Furthermore, the growth imbalance of the ulna and radius in long term would be avoided and the risk of ulnar impingement in the wrist joint would be reduced. Clinical surgeons should pay great attention to the early diagnose and treatmont which could signiifcantly lower the disability rate.
