Summary
Surgical repair of peripheral triangular fibrocartilage tears, excluding those causing distal radioulnar joint instability, yielded good to excellent outcomes in most patients. Open repair restored wrist function effectively.
Area of Science:
- Orthopedic Surgery
- Wrist Arthroscopy
- Sports Medicine
Background:
- Triangular fibrocartilage complex (TFCC) injuries are common in the wrist.
- Peripheral rim tears of the TFCC can cause significant pain and dysfunction.
- Distal radioulnar joint (DRUJ) instability is a potential complication.
Purpose of the Study:
- To evaluate the outcomes of open surgical repair for peripheral TFCC rim tears.
- To assess the effectiveness of TFCC repair in restoring wrist function.
- To analyze results based on tear location and surgical approach.
Main Methods:
- Retrospective review of 56 patients with TFCC injuries.
- Identification of 33 patients with peripheral rim tears without DRUJ instability.
- Open surgical repair using dorsal or ulnar recession approaches.
- Outcomes graded using the Mayo modified Green-O'Brien wrist score.
Main Results:
- Open repair of peripheral tears resulted in 26 good to excellent outcomes.
- 11 patients underwent ulnar recession for improved exposure and ulnar variance correction.
- A dorsal approach was used for 28 patients with radial and anterior rim tears.
Conclusions:
- Open surgical repair is an effective treatment for peripheral TFCC rim tears.
- Restoration of TFCC integrity leads to favorable functional outcomes.
- Surgical approach selection, including ulnar recession, can optimize results.
