Summary
This study reviews triangular fibrocartilage complex (TFCC) injuries, classifying traumatic and degenerative patterns. Arthroscopic debridement and the Wafer procedure show success for specific TFCC lesions.
Area of Science:
- Orthopedic Surgery
- Sports Medicine
- Hand and Wrist Surgery
Background:
- The triangular fibrocartilage complex (TFCC) is crucial for wrist stability and function.
- Acute and chronic TFCC lesions present diagnostic and management challenges.
Purpose of the Study:
- To review TFCC anatomy, biomechanics, and injury patterns.
- To propose an arthroscopic treatment strategy for various TFCC lesions.
- To evaluate the efficacy of specific arthroscopic procedures for TFCC injuries.
Main Methods:
- Arthroscopic evaluation of acute and chronic TFCC lesions.
- Classification of traumatic (Class 1A-1D) and degenerative (Class 2A-2E) TFCC injuries.
- Review of treatment outcomes for arthroscopic debridement and the Wafer procedure.
Main Results:
- Successful outcomes reported for arthroscopic debridement of horizontal TFCC tears (Class 1A).
- The Wafer procedure demonstrated success in treating degenerative TFCC lesions (Class 2C).
- A 2-year follow-up indicated positive results, with a recommendation for long-term monitoring.
Conclusions:
- A systematic classification aids in managing TFCC injuries.
- Arthroscopic interventions offer effective treatment for specific TFCC lesion types.
- Long-term follow-up is essential for assessing the durability of TFCC treatments.
