Abstract

Recent reports consider perilunate and lunate dislocation as different stages of radiologic manifestations of the same injury. Despite the severity of this type of injury, diagnosis of acute perilunate dislocations are occasionally unrecognized. In neglected cases for minimum 6 weeks after injury, treatment modality such as open reduction and intemal fixation, lunate excision, proximal row carpectomy, limited wrist arthrodesis are available, but there are few reports and follow up evaluations are often limited. Complications such as avascular necrosis, carpal instability and degenerative osteoarthritis are well known to result. We experienced 2 cases of open reduction for the old anterior dislocation of the lunate, which were diagnosed at 3 months and 6 months later after injury, and have been evaluated long term follow up over 2 years. The result is satisfactory now and, the literature is reviewed.
