Rare pediatric Galeazzi lesion with progressive wrist deformity.

Galeazzi injuries are rare in early childhood and may be missed at initial presentation. Undiagnosed instability of the distal radioulnar joint can lead to progressive deformity and functional impairment. We report a rare case of Galeazzi injury in early childhood that led to progressive wrist malalignment during growth. Over the years this resulted in a severe restriction of forearm rotation. Using computed tomography-based three-dimensional analysis, a multiplanar corrective osteotomy was planned with reference to the contralateral healthy side. The procedure reduced the initial supination deficit of 120° to 20° and restored excellent wrist function. Missed Galeazzi injuries in early childhood can result in progressive deformity and significant long-term functional limitations. Advanced three-dimensional imaging enables accurate analysis of complex deformities and facilitates corrective osteotomy. Even in delayed presentations, satisfactory functional recovery can be achieved with appropriate surgical planning.
