Biomechanical Analysis of Transosseous Repair Versus Combined Transosseous With Capsular Repair for Triangular Fibrocartilage Complex Tears With Instability.

Purpose: This study compared the biomechanical stability of transosseous repair and transosseous combined with capsular repair techniques to reattach the triangular fibrocartilage complex (TFCC) for distal radioulnar joint instability.

Methods: Eight adult cadaveric upper-extremity specimens were studied. Each underwent peripheral ulnar-sided detachment of the deep and superficial TFCC fibers and repair.

The optimal tension for the reconstruction of the distal radioulnar ligaments.

Purpose: This study aimed to investigate the optimal tension for the reconstruction of the distal radioulnar ligaments (DRULs) in the treatment of the distal radioulnar joint (DRUJ) instability.

Methods: A total of eight human cadaver upper extremities were used. First, the Tekscan sensor film system was used to measure the contact characteristics of the intact DRUJ.
