A Case for Acute Proximal Row Carpectomy for Perilunate Injuries.

Background: Perilunate injuries are complex injuries typically arising from high-energy injuries to the wrist. Standard treatment involves open reduction and internal fixation with ligamentous reconstruction; however, outcomes are fraught with complications including pain, stiffness, and arthrosis. Several case reports have demonstrated the role of proximal row carpectomy as a salvage procedure for complex carpal trauma in the setting of significant cartilage injury or bone loss. The authors believe that proximal row carpectomy may be an appropriate acute treatment in certain patient populations, with functional results similar to those obtained with ligamentous reconstruction.

Methods: A retrospective review of two cases with perilunate dislocations managed with primary proximal row carpectomy are presented.

Results: At greater than 1-year follow-up, both patients had stable radiocarpal alignment. Quick-DASH scores were 22.7 and 27.3.

Conclusion: Primary proximal row carpectomy is a treatment option in the acute setting for perilunate injuries in elderly, lower-demand patients. Functional results are similar to those obtained with ligamentous reconstruction, with a shorter recovery period. Level of Evidence: IV.
