[Lunocapitate shortening arthrodesis after scaphoid and triquetrum resection: treatment of Watson stage III advanced scaphoid periarthrosis].
OBJECTIVE
Between 1993 and 2000, 16 patients with scaphoid periarthrosis (Watson stage III) were treated by lunocapitate shortening arthrodesis after resection of the scaphoid and triquetrum. These patients were reviewed to evaluate outcome.


METHODS
Thirteen patients had antecedent trauma with scaphoid nonunion (SNAC, n=9) or scapholunate advanced collapse (SLAC, n=4). The remaining three patients had chondrocalcinosis.


RESULTS
Clinical and radiological results were encouraging at a mean follow-up of 3 years (1-7 years). Fourteen patients were very satisfied and two experienced partial improvement. Persistent pain relief as well as 11% improved muscle power was achieved. Mean improvement of joint motion was 12 degrees.


CONCLUSIONS
This technique has shown better global results than 4-corner arthrodesis. It can be applied if capitate arthrodesis is performed. Results are comparable to those of proximal row carpectomy.
