In human anatomy, the radial (RCL) and ulnar (UCL) collateral ligaments of the metacarpophalangeal joints (MCP) of the hand are the primary stabilisers of the MCP joints. [1] A collateral ligament flanks each MCP joint - one on either side. Each attaches proximally at the head of the metacarpal bone, and distally at the base of the phalynx.
During activities such as overhand baseball pitching, this ligament is subjected to extreme tension, which places the overhand-throwing athlete at risk for injury. [4] 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 ...
Its borders present continuations of the groove on the margin of the superior surface; they serve for the attachment of ligaments: the back part of the ulnar collateral ligament medially, and the posterior ligament laterally. From the medial border a part of the flexor carpi ulnaris arises; while to the lateral border the anconeus is attached.
The ulnar collateral ligament of elbow joint is in relation with the ulnar nerve. The nerve is the largest in the human body unprotected by muscle or bone, so injury is common. [ 1 ] This nerve is directly connected to the little finger , and the adjacent half of the ring finger , innervating the palmar aspect of these fingers, including both ...
The shoulder joint has a very loose joint capsule, which can sometimes predispose the shoulder to dislocate. [citation needed] The "U shaped" dependent portion of the axillary part of the capsule ,located between the anterior and posterior bands of inferior glenohumeral ligament, is called "axillary pouch".

The oblique cord is a ligament between the ulnar and radius bones in the forearm near the elbow.It takes the form of a small, flattened band, extending distally and laterally, from the lateral side of the ulnar tuberosity at the base of the coronoid process to the radius a little below the radial tuberosity. [1]
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 ...
Ulnar collateral ligament (or UCL) may refer to: Ulnar carpal collateral ligament; Ulnar collateral ligament of elbow joint; Ulnar collateral ligament of thumb
