[Wrist arthrodesis: alternative to resection of the proximal carpal bones?].

The results of a series of 36 post-traumatic radio-carpal arthrodeses were compared with those of the series of resection of the first row of carpal bones reported during the round table. The advantages and disadvantages of both procedures were discussed. Arthrodesis results in: 1) loss of grip strength in all cases, averaging 41%; 2) persistent pain in 78% of cases; 3) impairment of function resulting from blocking of the wrist. After the procedure, average time off work is 15 months, level of permanent disability was 30%, and 20% of patients returned to their previous jobs. These figures could be used as arguments against arthrodesis. However, they must be taken in context: final arthrodesis, usually performed on manual workers, is often chosen when resection of the first row of carpal bones would obviously be insufficient, for example, when severe arthritis of the head of the capitate is present.
