Partial excision of the triangular fibrocartilage complex articular disk: a biomechanical study.
A cadaver study was performed to evaluate the effects of partial and complete excisions of the articular disk of the triangular fibrocartilage complex on the kinematics of the distal radioulnar joint and the structural integrity of the triangular fibrocartilage. An excision that did not violate the peripheral 2 mm of the disk and that comprised less than two thirds of the disk area resulted in no significant kinematic or structural changes, but larger excisions produced measurable changes. These results provide further support for limited excision of central triangular fibrocartilage complex tears.
