Triangular Fibrocartilage
What is Triangular Fibrocartilage?
Triangular fibrocartilage (TFC) refers to the fibrocartilaginous structure located on the ulnar side of the wrist that stabilizes the distal radioulnar joint.
- Acts as a cushion between the ulna and carpal bones
- Essential for wrist stability
Overview of the Condition
Injury or degeneration of the TFC can lead to pain, weakness, and clicking in the wrist.
Symptoms
- Ulnar-sided wrist pain
- Clicking or snapping sensation
- Weak grip strength
Causes
Trauma, overuse, or degenerative changes can damage the triangular fibrocartilage.
Diagnosis
Diagnosis is made with clinical examination and imaging studies, such as MRI or arthroscopy.
Treatment Options
- Conservative treatment with rest and immobilization
- Physical therapy
- Surgical repair or debridement for persistent cases
Conservative Management
Initial management includes rest, wrist splinting, and anti-inflammatory medications.
Rehabilitation Exercises
- Wrist range-of-motion exercises
- Strengthening exercises
- Gradual return to activity
Surgical Options
Arthroscopic or open surgical repair may be indicated for significant TFC injuries.
Anatomy Overview
The triangular fibrocartilage is a key structure in the ulnar aspect of the wrist that supports joint stability.
Affected Areas
- Ulnar side of the wrist
- Distal radioulnar joint
