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.
Elbow pain generally refers to discomfort in the joint between the upper arm and forearm. Elbow pain is a common complaint in both the emergency department and in primary care offices.

[3] [4] The term elbow is specifically used for humans and other primates, and in other vertebrates it ...
The arm proper (brachium), sometimes called the upper arm, [5] the region between the shoulder and the elbow, is composed of the humerus with the elbow joint at its distal end. The elbow joint is a complex of three joints — the humeroradial, humeroulnar, and superior radioulnar joints — the former two allowing flexion and extension whilst ...
It can affect one or more joints throughout the body. Hypermobile joints are common and occur in about 10 to 25% of the population, [3] but in a minority of people, pain and other symptoms are present. This may be a sign of hypermobility spectrum disorder (HSD). Hypermobile joints are a feature of genetic connective tissue disorders such as ...
