The Radial Collateral Ligament of Thumb (RCLT) is a crucial ligament located in the human hand. It is specifically found in the thumb, where it plays a significant role in maintaining the thumb's stability and mobility.
Anatomy[edit]
The Radial Collateral Ligament of Thumb is situated on the radial side of the metacarpophalangeal joint (MCP joint) of the thumb. It extends from the radial tubercle of the metacarpal bone to the base of the proximal phalanx of the thumb.
Function[edit]
The primary function of the RCLT is to provide stability to the thumb, particularly during movements such as pinching and gripping. It restricts excessive movement in the thumb, preventing potential injuries.
Clinical Significance[edit]
Injury to the Radial Collateral Ligament of Thumb often results from forceful abduction or hyperextension of the thumb. This can lead to a condition known as Skier's thumb, which is a common injury among athletes and individuals involved in physical activities.
Treatment[edit]
Treatment for injuries to the RCLT typically involves immobilization of the thumb, physical therapy, and in severe cases, surgical intervention. Early diagnosis and treatment are crucial to prevent long-term complications such as chronic instability and arthritis.
Etymology[edit]
The term "Radial Collateral Ligament of Thumb" is derived from its location and function. "Radial" refers to the radial side of the thumb, "Collateral" indicates its role in providing lateral stability, and "Ligament" signifies its connective tissue nature.
