Causes, Diagnosis & Treatments For TFCC Injuries Of The Wrist
The Anatomy Of TFCC: The Triangular Fibrocartilage Complex (TFCC) is a long ligament structure placed along the little finger’s outer edge, passing over the carpel bones and connecting to the radius and ulna bones at the wrist joint. It collectively comprises the triangular fibrocartilage disc (TFC), extensor carpi ulnaris tendon subsheath, ulnotriquetral and ulnolunate ligaments, dorsal and volar distal radioulnar ligaments, the ulnocarpal collateral ligament, and meniscal homolog. The TFC has some blood vessels on the ulnar aspect, while the rest of the structure is avascular. The meniscal homolog is mostly composed of various loose connective tissues. Typically, it acts as a stabilizer for the ulnar aspect of the wrist and enables load transmission while rotating or gripping the wrist. What Are TFCC injuries? Ulnar-sided wrist injuries or tears are directly or indirectly associated with TFCC injuries. As TFCC comprises multiple ligaments, any excess tension or impact w...
