[Proximal row carpectomy: 25 cases].
OBJECTIVE
Resection of the proximal row of the carpus which simplifies the radiocarpal joint is mainly performed for advanced collapse. With the development of several therapeutic alternatives, further study of outcome is warranted to better identify indications.


METHODS
Twenty-five patients who underwent proximal row carpectomy between January 1999 and February 2004 were reviewed clinically and radiologically at 30 months mean follow-up. Three main etiologies were noted: scaphoid fracture (n=9), scapholunate dissociation (n=9), Kienböck disease (n=6). A posterior approach was used for all patients. Outcome was assessed clinically (pain, force, mobility), radiologically (carpal height, radiocapital space), and subjectively by the patient. Resumption of occupational activity was noted as were the Cooney and Culp scores.


RESULTS
Average flexion-extension was 60 degrees . Average wrist force was 65% of the healthy side. Pain improved in 88% of wrists and the mean subjective score was 15.2. The mean Cooney and Culp scores were 58 and 67.8 respectively. A reduction in the height of the new articular space was not correlated with less favorable clinical outcome. Outcome in patients with Kienböck disease were less favorable than in trauma patients but the difference did not reach significance.


CONCLUSIONS
First row carpectomy is a paliative procedure which should only be performed when conservative treatment is no longer a valid option. Indications should be limited to Watson grade II, before cartilaginous damage affects the head of the capitatum. New techniques such as fusion-shortening, theoretically similar to resection, can now be used for advances collapse. We prefer resection over four-bone arthrodesis because of the lower risk of complications. In Kienböck disease, first row carpectomy should only be used for selected patients (Lichtmann III) due to the risk of early degeneration of the capitatum and radius heads.
