Long-term follow-up of an undiagnosed trans-scaphoid perilunate dislocation demonstrating articular remodeling and functional adaptation.

The most common perilunate dislocation is the trans-scaphoid dorsal perilunate variant. It is estimated that up to 25% of perilunate injuries are diagnosed late. We report 66-year follow-up of an unreduced, previously undiagnosed trans-scaphoid perilunate dislocation of the wrist. At follow-up, unique post-traumatic articular remodeling was seen on wrist radiographs, and the patient had only a mild functional deficit.
