The humeroulnar joint (ulnohumeral or trochlear joint [1]) is part of the elbow-joint. It is composed of two bones, the humerus and ulna, and is the junction between the trochlear notch of ulna and the trochlea of humerus. [1] It is classified as a simple hinge-joint, which allows for movements of flexion, extension and circumduction.
Anatomy of the ulnar collateral ligament in the pitcher's elbow. Pain along the inside of the elbow is the main symptom of this condition. Throwing athletes report it occurs most often during the acceleration phase of throwing. The injury is often associated with an experience of a sharp “pop” in the elbow, followed by pain during a single ...
Acute or chronic disruption and/or attenuation of the ulnar collateral ligament often result in medial elbow pain, valgus instability, and impaired throwing performance. There are both non-surgical and surgical treatment options. [5]
Close to the elbow, the ulna has a bony process, the olecranon process, a hook-like structure that fits into the olecranon fossa of the humerus. This prevents hyperextension and forms a hinge joint with the trochlea of the humerus. There is also a radial notch for the head of the radius, and the ulnar tuberosity to which muscles attach.
Elbow pain is a relatively vague symptom that could be the result of any number of possible pathologies. On a cellular level the pain, aka nociception , is conveyed through nerves in the elbow. Theses nerve cells, aka neurons , are activated and or compressed due to local tissue damage and swelling, which ultimately leads to pain and possibly ...
Examples of injuries affected on an elbow include; Carpal tunnel syndrome, Radial Tunnel Syndrome and tennis elbow, all of which are due to tendon and ligament damage from overuse or strain. [ 7 ] [ 2 ] Distal humeral fractures are related to high energy trauma from falling from a height or in a motor vehicle accident, this results in stiffness ...
Repetitive overuse of the forearm, as seen in tennis or other sports, can result in inflammation of "the tendons that join the forearm muscles on the outside of the elbow. The forearm muscles and tendons become damaged from overuse. This leads to pain and tenderness on the outside of the elbow." [3]
The composition of the triangular ligamentous structure on the lateral side of the elbow varies widely between individuals [1] and can be considered either a single ligament, [2] in which case multiple distal attachments are generally mentioned and the annular ligament is described separately, or as several separate ligaments, [1] in which case parts of those ligaments are often described as ...
