Comparative Study
Biomechanical comparison of transosseous and capsular repair of peripheral triangular fibrocartilage tears.
The purpose of this study was to biomechanically compare the repair strength of peripheral triangular fibrocartilage complex (TFCC) repairs to the distal ulna using transosseous sutures (group I) versus TFCC repairs to the extensor carpi ulnaris tendon subsheath and surrounding dorsal capsule (group II). ⋯ While disruption of the TFCC does significantly increase distal radioulnar joint (DRUJ) instability and repair of the TFCC does significantly restore DRUJ stability, the results of this study do not show a significant biomechanical difference between the 2 TFCC repair techniques in a cadaveric model.
