Clinically Relevant Anatomy
[edit | edit source]
The Triangular Fibrocartilage Complex is the ligamentous and cartilaginous structures that separate the radiocarpal from the distal radioulnar joint. The TFCC consists of an articular disc, meniscus homologue, ulnocarpal ligament, dosal & volar radioulnar ligament and extensor carpi ulnaris sheath.
Origin: Medial border of distal radius
Insertion: Base of ulnar styloid
Vascular Supply: central disc is avascular, peripheral blood vessels penetrate TFCC margins
Function of TFCC:
- Main stabilizer of distal radioulnar joint
- Volar portion of TFCC prevents dorsal displacement of ulna and is tight in pronation
- Dorsal portion of TFCC prevents volar displacement of ulna and is tight in supination
2. Contributes to ulnocarpal stability
