Traumatic Mechanisms andTherapeutic Results of the Perilunate Injuries

摘要

Mayfield et al. suggested the detailed reports about perilunate instability which was one of the unusual injuries. In this study, we evaluate the eighteen patients who have had a perilunate injury with dislocation or fracture, and study the pathomechanics and surgical treatment on the patients. When the pathomechanics was estimated based on the Mayfield's criteria, seventeen patients were classified as stage 3. However, only one case was extremely unusual and should be classified as the subtype of stage 2. There was no osteoarthritic changes and instability on the radiographic findings of the wrist joint.
