Answer

The tendons are relatively hypovascular proximal to the tendon insertion. This hypovascularity may predispose the tendon to hypoxic tendon degeneration and has been implicated in the etiology of tendinopathies. [2] Most typically, the primary pathology is tendinosis of the extensor carpi radialis brevis (ECRB) tendon 1-2 cm distal to its attachment on the lateral epicondyle. [2, 3]
