Treatment of chronic perilunate dislocations.
Fifteen patients with 16 perilunate dislocations that had been untreated for a minimum of 6 weeks after the injury were evaluated after subsequent treatment at a mean of 6.4 years. The median time from injury to definitive treatment was 17 weeks. Ten wrists had completely ligamentous injuries and six had fracture-dislocations. Treatment consisted of open reduction and internal fixation in six patients, isolated carpal bone excision in four, wrist arthrodesis in two, proximal row carpectomy in two, and bilateral carpal tunnel release in one. In this series the results of excision of the lunate or scaphoid alone were uniformly poor. One of the two patients who had a proximal row carpectomy required secondary radial styloidectomy, and a pseudarthrosis developed in one of the two patients who had a wrist arthrodesis. All six patients treated by open reduction and internal fixation had satisfactory outcomes and none required additional surgery.
