Subcutaneous bursitis:Repeated friction and pressure on the bursa can cause it to become inflamed. Because this bursa lies relatively superficially, it can also become infected (e.g. skin laceration from a fall on the elbow) Subtendinous bursitis:This is caused by repeated flexion and extension of the forearm, commonly seen in assembly line workers...
An elbow dislocation usually occurs when a young child falls on a hand with the elbow flexed. The distal end of the humerus is driven through the weakest part of the joint capsule, which is the anterior side. The ulnar collateral ligament is usually torn and there can also be ulnar nerve involvement Most elbow dislocations are posterior, and it is ...
Most of the flexor and extensor muscles in the forearm have a common tendinous origin. The flexor muscles originate from the medial epicondyle, and the extensor muscles from the lateral. Sportspersons can develop an overuse strainof the common tendon – which results in pain and inflammation around the area of the affected epicondyle. Typically, ten...
A supracondylar fracture usually occurs due to a fall onto on outstretched, extended hand in a child (95%) but more rarely can occur by a direct impact onto a flexed elbow. It is typically a transversefracture, spanning between the two epicondyles in the relatively weak epicondylar region formed by the olecranon fossa and coronoid fossa which lie o...

Jul 30, 2021 · The elbow is a synovial joint that aids in flexion and extension. It is a crossing point for the nerves and blood vessels of the upper arm and forearm. Many injuries and conditions...
Elbow, in human anatomy, hinge joint formed by the meeting of the humerus (bone of the upper arm) and the radius and ulna (bones of the forearm). The elbow allows the bending and extension of the forearm, and it also allows the rotational movements of the radius and ulna that enable the palm of the.
Jul 24, 2023 · The elbow is a complex synovial joint which allows for significant motion and function primarily in the form of extension and flexion, however, the elbow joint also facilitates motion in the hand in the form of supination and pronation of the forearm.
