The Triangular Fibrocartilage Complex (TFCC) is a vital, complex anatomical structure located on the ulnar aspect of the wrist. What is its primary biomechanical function during normal, heavy-load upper extremity kinematics?
A
To provide exclusive, retrograde intraosseous blood supply to the proximal pole of the scaphoid.
B
To provide critical ligamentous stability to the distal radioulnar joint (DRUJ) and act as a shock absorber for the ulnar carpus.
C
To serve as the primary, rigid attachment site for the extensor carpi radialis brevis tendon.
D
To act as a physical barrier preventing volar subluxation of the median nerve during severe wrist flexion.
