AbstractThe triangular fibrocartilage complex (TFCC) has an important role in the stability of the distal radioulnar joint (DRUJ) stability. We designed a new method of TFCC tear repair that has satisfactory post-operative DRUJ stability. From May 2004 to August 2010, 14 patients who underwent this operation were reviewed. The average post-operative follow-up period was 8.2 months; 66.7% of the patients with TFCC tear in sigmoid notch had clinical DRUJ instability, while only 50% of tear in fovea and 16.7% of tear in base of ulnar styloid had clinical DRUJ instability. Transosseous suture via inside-outside technique was used for repair. At the final follow-up, all 14 patients have soft end point with < 5 mm translations of the DRUJ shown by the stress test. Based on this small sample with satisfactory outcome assessed by the Mayo modified wrist score and DRUJ stability, we recommend TFCC tear in sigmoid notch, which has a higher chance of DRUJ instability, to be repaired by transosseous suture.
