What is lateral epicondylitis more commonly known as?
Tennis elbow (lateral epicondylitis) is a painful condition that occurs when tendons in your elbow are overloaded, usually by repetitive motions of the wrist and arm. Despite its name, athletes aren’t the only people who develop tennis elbow.
Which nerve is affected in lateral epicondylitis?
Posterior interosseous nerve (PIN) entrapment (also known as ‘radial tunnel syndrome’). Nerve compression produces neuropathic pain in the lateral forearm.
What is the differential diagnosis for lateral epicondylitis?
Conditions that the physician should consider include lateral epicondylitis, medial epicondylitis, radial tunnel syndrome, intra-articular pathology including radiocapitellar chondral lesions, cervical radiculopathy, ulnar neuropathy, elbow overuse as a compensatory mechanism, inflammation/edema of the anconeus, and …
How do you differentiate lateral epicondylitis?
The primary difference between them is the part of the elbow affected. Tennis elbow affects the lateral or “out” side, while golfer’s elbow affects the medial or “in” side.
Which nerve is involved in lateral epicondylitis?
Which muscles are involved in lateral epicondylitis?
Extensor carpi radialis brevis (ECRB) is the most commonly affected muscle, but supinator and other wrist extensors such as extensor carpi radialis longus, extensor digitorum, extensor digiti minimi and extensor carpi ulnaris can be involved.
Which muscles are most affected by tennis elbow?
The exact tendon most commonly involved in tennis elbow connects to a muscle called the extensor carpi radialis brevis. This muscle becomes overused with repetitive arm and wrist movements, such as in painting; using hand tools, such as screwdrivers and hammers; or from long hours of manipulating a computer mouse.
What nerve runs through lateral epicondyle?
A consistent lateral epicondyle innervation was identified from the posterior cutaneous nerve of the forearm. The nerve originates at the posterolateral midhumeral level from the radial nerve. Along its path, it branches approximately 5-8 cm above the lateral epicondyle into anterior and posterior branches.
How can you distinguish between medial and lateral epicondylitis?
Medial epicondylitis produces pain in the inner part of the elbow, while lateral epicondylitis produces pain in the outer elbow. The pain usually gets worse during activity that stresses the elbow tendons, leading to soreness and tenderness at either the inner or outer elbow.
What is the difference between lateral epicondylitis and medial epicondylitis?
Tennis elbow or lateral epicondylitis affects the outer or lateral side of your elbow. These are the muscles you use to bend your wrist backward and straighten your fingers. Golfer’s elbow or medial epicondylitis affects the inner or medial side of your elbow.
What muscles do golfers elbow?
Medial epicondylitis, also called golfer’s elbow, is tendinopathy of the medial common flexor tendon of the elbow due to overload or overuse. It may also be referred to as pitcher’s elbow, or termed tendinosis or epicondylalgia instead of epicondylitis.
