Nondissociative carpal instability is instability of an entire carpal row and can
lead to vague ulnar-sided wrist pain as well as a clunking wrist. The etiology of
this process is most often generalized ligamentous laxity; however, it can infrequently
occur as a result of trauma or malalignment of the radiocarpal joint. Whereas treatment
remains controversial, the literature supports nonsurgical management and includes
patient education, dynamic placement of orthoses, proprioceptive therapy, and extensor
carpi ulnaris strengthening. If extensive nonsurgical therapy fails, surgical intervention
includes soft tissue and bony procedures, all with high complication and failure rates
and limited long-term outcome data.
