What is the Epicondylus?
ep·i·con·dyle (ep’i-kon’dīl) [TA] A projection from a long bone near the articular extremity above or on the condyle. Synonym(s): epicondylus [TA] . [epi- + G. kondylos, a knuckle]
What is the lateral epicondyle of the humerus?
Lateral Epicondylitis (Tennis Elbow) The elbow joint is made up of the bone in the upper arm (the humerus) and one of the bones in the lower arm (ulna). The bony prominences, or bumps, at the bottom of the humerus are called the epicondyles. The bump on the outer side of the elbow is called the lateral epicondyle.
What muscles attach to lateral epicondyle of humerus?
The extensor carpi radialis brevis originates from the lateral epicondyle of the humerus by a common tendon shared with other muscles of the posterior superficial compartment including the extensor carpi ulnaris, extensor digiti minimi, and extensor digitorum.
Which nerve is felt behind the medial epicondyle of humerus?
the ulnar nerve
Typically, injury to the ulnar nerve happens as it runs behind the medial epicondyle of the humerus, and can occur with a fracture at that site. Injury to the ulnar nerve will present with numbness and paresthesia in the little finger, the medial half of the ring finger, and the medial side of the palm.
What causes lateral epicondylitis?
Lateral epicondylitis, or tennis elbow, is swelling or tearing of the tendons that bend your wrist backward away from your palm. It’s caused by repetitive motion of the forearm muscles, which attach to the outside of your elbow. The muscles and tendons become sore from excessive strain.
What causes lateral epicondyle pain?
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.
What does lateral epicondyle attach to?
The lateral epicondyle is a small, tuberculated eminence, curved a little forward, and giving attachment to the radial collateral ligament of the elbow-joint, and to a tendon common to the origin of the Supinator and some of the Extensor muscles.
What causes pain on the inner side of the elbow?
Inner elbow pain is often a result of medial epicondylitis, or golfer’s elbow. In this form of tendonitis (acute) or tendinopathy (chronic), the inner elbow tendons become irritated and painful. A person can also experience wrist pain and/or forearm weakness.
What are the parts of the humerus?
The humerus is the longest and largest bone of the upper limb. It consists of a proximal end, a shaft and a distal end, all which contain important anatomical landmarks. The humerus articulates with the scapula proximally at the glenohumeral joint so it participates in the movements of the shoulder.
What is the lateral bone of the forearm?
radius
The ulna is the medial bone of the forearm. It runs parallel to the radius, which is the lateral bone of the forearm ((Figure)).
How is epicondylitis diagnosed?
Lateral epicondylitis is diagnosed by an exam of the elbow joint. The healthcare provider may need an X-ray or MRI to see what’s causing the problem. An EMG may be done to look for nerve problems. Lateral epicondylitis can be treated with rest and medicines to help with the inflammation.
What nerve passes near the lateral epicondyle of the humerus?
The ulnar nerve lies just caudal to the medial epicondylar crest. The median nerve and brachial artery pass through the supracondylar foramen and run further cranially below the pronator muscle.
How do you fix inner elbow pain?
Therapy
- Rest. Put your golf game or other repetitive activities on hold until the pain is gone.
- Ice the affected area. Apply ice packs to your elbow for 15 to 20 minutes at a time, three to four times a day for several days.
- Use a brace.
- Stretch and strengthen the affected area.
