Summary: Two fractures of the distal radius seemingly with lack of involvement of the distal radial physis are presented. Nevertheless, complete arrest of the adjacent physis occurred, suggesting a Salter-Harris V mechanism of injury to the vulnerable distal radial physis. Ulnar "overgrowth" produced impingement of the carpus and functional complaints sufficient to warrant treatment. In this clinical setting, an ulnar-shortening osteotomy done at skeletal maturity resulted in marked improvement in the range of motion at the radiocarpal joint and corresponding improvement in function for both patients so treated.
