Intercarpal arthrodesis in the management of chronic carpal instability after trauma.
A retrospective review of five patients with chronic carpal instability resulting from trauma suggests that this condition can be successfully treated by intercarpal arthrodesis. Scaphoid-lunate fusion was used to treat chronic dorsal intercalary segment instability, while scaphoid-capitate-lunate fusion was used to treat chronic palmar intercalary segment instability. Results after intercarpal arthrodesis were consistently good, with restoration of painless function, preservation of grip strength, and a high degree of patient satisfaction. Although a fibrous union was obtained in two of the three scaphoid-lunate arthrodeses, this did not prejudice a good clinical outcome. These results compare favorably to those with other treatment modalities, including ligamentous reconstructions with tendons. Based on these findings, a more extensive clinical trial of intercarpal arthrodesis to treat chronic carpal instability appears warranted.
