Observational analysis reveals that bifascicular reconstruction restores stability in the trapeziometacarpal joint, suggesting effective surgical options.
The monofascicular reconstruction technique seems to be insufficient to stabilize the TM joint. Dorsal ligament reconstruction with the bifascicular technique restores the original stability of the TM joint. Moreover, it is not necessary to reconstruct the ulnar ligament to restore the dorsoradial stability of the TM joint after bifascicular reconstruction.
