What is a radial collateral ligament (RCL) tear? The radial collateral ligament (RCL) is a strong, short, thin band of tissue that connects from the humerus (upper arm bone) to the radius (one of two forearm bones). The role of the RCL is to provide stability against inner …

2024年1月12日 · Thumb Collateral Ligament Injuries, most commonly ulnar collateral (UCL), are athletic injuries that lead to a decrease in effective thumb pinch and grasp. Diagnosis relies upon thumb MCP radial-ulnar stress exam and MRI studies.

Injuries to the collateral ligaments of the thumb metacarpophalangeal (MP) joint, which range from mild sprains to complete ruptures, are among the most common injuries of the hand. The majority of these injuries involve the ulnar collateral ligament (UCL), while radial collateral ligament (RCL) injuries occur far less frequently.

Chronic RCL insufficiency contributes to significant thumb MCP instability that can lead to loss of pinch strength and eventual progression to degenerative changes of thumb metacarpophalangeal joint. While physical exam is the cornerstone of diagnosis, stress radiographs and advanced imaging may be helpful in some cases.

The Lateral collateral ligament of the elbow (LCL) is sometimes also called the radial collateral ligament (RCL). This ligament can become sprained or torn as a result of a sports injury. Because the LCL has an important role in supporting the elbow, injury can lead to elbow instability.

Elbow lateral collateral ligament (LCL) strains or tears are those that damage the soft tissue in our elbow's lateral collateral ligament complex (LCLC). The LCLC consists of four ligaments, of which, only two are typically referred to as the lateral collateral.

By enlarge, injury to the ulnar collateral ligament (UCL) is more common than the radial collateral ligament (RCL) accounting for 60–90% of ligamentous collateral injury cases at the MCP joint of the thumb [1]. This review will outline the relevant clinical anatomy, mechanisms of injury, and treatment options available.

Pt. was a pro-tennis player, presented with RCL strain grade II on MRI, secondary to incorrect taping of the wrist, which resulted in incorrect racquet handling, leading to strain of RCL of the index finger. This patient was treated with night MP blocking splint (hand based, IP’s free) and a day wide buddy loop splint.

The Metacarpophalangeal (MCP) joint of the thumb are stabilize by two major ligaments. The ulnar collateral ligament (UCL) and the Radial collateral ligament (RCL) . The UCL is more commonly injured, usually from forced radial deviation (abduction) of the thumb, while the RCL are rarely injuried.

What is Radial Collateral Ligament Sprain/Strain? The lateral collateral ligament of the elbow, also called the radial collateral ligament, is located on the outside or thumb side of the elbow and prevents medial (inside) to lateral (outside) translation of the elbow.
