Arthroscopic Capsular Repair for Triangular Fibrocartilage Complex Tears.

 The triangular fibrocartilage complex (TFCC) lesions are frequently implicated as a cause of ulnar wrist pain following impact and loading injuries. The objective of this study was to describe the clinical outcomes following TFCC lesion repair with the arthroscopic outside-in technique.  We inserted a 21-gauge needle with 4-0 nylon loop perpendicular to the injured triangular fibrocartilage (TFC).

Effects of peripheral tears of the triangular fibrocartilage complex on distal radioulnar joint stability: A biomechanical study.

Background: Peripheral triangular fibrocartilage complex (TFCC) tears may induce instability of the distal radioulnar joint (DRUJ). In this biomechanical study, simulated peripheral tears of the TFCC were examined on the stability of the DRUJ. Restabilization effect of the DRUJ by ulnar shortening and direct repair of those injuries were sequentially examined.

Congenital defects of the flexor digitorum profundus tendon of the little finger.

The cases of two patients, a four-year-old boy and an eight-year-old boy, who had been incapable of active flexion of the little finger since birth, are presented. They were capable of active flexion of the metacarpophalangeal (MP) joint, but not of the proximal interphalangeal (PIP) and distal interphalangeal (DIP) joints. They were diagnosed with a defect of the flexor digitorum profundus (FDP) tendon of the little finger and underwent surgery.
