Management of Nondissociative Instability of the Wrist

Published:December 19, 2019DOI:https://doi.org/10.1016/j.jhsa.2019.10.030
      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.
