Medial epicondylitis of the elbow is a classic overuse injury with inflammation of the common flexor-pronator origin.
These tendons connect the forearm muscles to their origin from the arm bone. These muscles function to move the wrist, hand and fingers; most sensitive region is located near the origin of the wrist flexors
on the medial epicondyle of the humerus.
In addition to golf, tennis or other racket sports, throwing sports and other activities such as painting, raking leaves and typing/computer mouse can aggravate medial elbow pain (Stark and Bowes, 2010).
It usually responds well to nonoperative treatment, however, in some cases a surgical debridement and repair is necessary (Vinod and Ross, 2015). Usually surgery is offered after 3-6 months conservative therapy without progress (Vinod and Ross, 2015).
