Golfer's elbow, or medial epicondylitis, is tendinosis (or more precisely enthesopathy) of the medial common flexor tendon on the inside of the elbow. [1] It is similar to tennis elbow , which affects the outside of the elbow at the lateral epicondyle.
Schematic diagram of the medial side of the elbow showing the ulnar nerve passing through the cubital tunnel. Chronic compression of the ulnar nerve in the cubital tunnel is known as cubital tunnel syndrome. [4] There are several sites of possible compression, traction or friction of the ulnar nerve as it courses behind the elbow. [5]
The posterior oblique originates at the medial epicondyle and inserts along the mid-portion of the medial semilunar notch. [11] It applies more stability against valgus stress when the elbow is flexed rather than extended. The transverse ligament connects to the inferior medial coronoid process of the ulna to the medial tip of the olecranon. [11]
Note that this ligament is also referred to as the medial collateral ligament [1] and should not be confused with the lateral ulnar collateral ligament (LUCL). [ 2 ] The anterior portion , directed obliquely forward, is attached, above, by its apex, to the front part of the medial epicondyle of the humerus ; and, below, by its broad base to the ...
Palpating the medial and lateral epicondyles to assess for pain or tenderness can help determine whether the epicondylitis is medial or lateral, and what muscle group is overused. A common diagnostic test utilized for lateral epicondylitis is to assess resisted wrist extension, along with resistance to the middle finger.
Osborne's ligament, also Osborne's band, Osborne's fascia, Osborne's arcade, arcuate ligament of Osborne, or the cubital tunnel retinaculum, refers to either the connective tissue which spans the humeral and ulnar heads of the flexor carpi ulnaris (FCU) or another distinct tissue located between the olecranon process of the ulna and the medial epicondyle of the humerus.
