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]
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.
The medial epicondyle is often the final growth plate (ossification center) to ossify in the elbow. Growth plates are particularly vulnerable to injury compared to bone. Children can have an open medial epicondyle growth plate until age 13–17 years old, thus making the medial epicondyle more susceptible to injury. [3] Medial epicondyle ...
A common diagnostic test utilized for lateral epicondylitis is to assess resisted wrist extension, along with resistance to the middle finger. If symptoms can be reproduced, it could indicate lateral epicondylitis. [5] For medial epicondylitis, resisted wrist flexion and pronation would be assessed by your provider.
The ulnar collateral ligament has its apex on the medial epicondyle. Its anterior band stretches from the anterior side of the medial epicondyle to the medial edge of the coronoid process, while the posterior band stretches from posterior side of the medial epicondyle to the medial side of the olecranon. These two bands are separated by a ...
The medial epicondyle protects the ulnar nerve, which runs in a groove on the back of this epicondyle. The ulnar nerve is vulnerable because it passes close to the surface along the back of the bone. Striking the medial epicondyle causes a tingling sensation in the ulnar nerve. This response is known as striking the "funny bone". [1]
The artery runs medial to the biceps tendon. The brachial pulse may be palpated in the cubital fossa just medial to the tendon. The area just superficial to the cubital fossa is often used for venous access in procedures such as injections and obtaining samples for blood tests. A number of superficial veins can cross this region.
