The radial collateral ligament of the thumb extends from the first metacarpal head to the proximal phalanx of the thumb. It is located on the radial side of the joint and is weaker than the ulnar collateral ligament of the thumb. [1]
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.
The scapholunate ligament is an intraarticular ligament binding the scaphoid and lunate bones of the wrist together. It is divided into three areas, dorsal, proximal and palmar, with the dorsal segment being the strongest part. [3] It is the main stabilizer of the scaphoid. In contrast to the scapholunate ligament, the lunotriquetral ligament ...

Gamekeeper's thumb and skier's thumb are two similar conditions, both of which involve insufficiency of the ulnar collateral ligament (UCL) of the thumb. The chief difference between these two conditions is that skier's thumb is generally considered to be an acute condition acquired after a fall or similar abduction injury to the metacarpophalangeal (MCP) joint of the thumb, whereas gamekeeper ...
Lengthening of the radial collateral ligament is only indicated when the clinodactyly is still present after reconstruction of the ulnar collateral ligament. [ 8 ] - trapezoidal phalanx and older than six years: partial removal of the extra phalanx with correction of the angle.
The collateral ligaments of interphalangeal joints are ligaments of the interphalangeal joints of the hand. They limit extension at these joints (together with the palmar ligaments). [1] On each side of the interphalangeal joints of the fingers are diagonally placed fibrous bands.
The ulnar thumb is preferably preserved as it is the more developed one in most cases. [12] By detaching the radial collateral ligament from distal to proximal, a periosteal sleeve can be preserved. [46] In this way, the radial collateral band of the radial digit will function as the absent radial collateral ligament of the preserved ulnar thumb.
