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.

The ulnar collateral ligament (UCL) and radial collateral ligament (RCL) are the primary static stabilizers of the MCP with additional stability provided by articular surface congruity, the dorsal capsule, and the volar plate.

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.

Injuries to the radial collateral ligament (RCL) of the thumb are thought to be relatively uncommon, especially when compared to the ulnar collateral ligament. However, the radial collateral ligament is increasingly recognized as critical for the overall …

2008年5月1日 · Radial collateral ligament (RCL) injuries of the thumb are relatively common although they are less common than ulnar collateral ligament injuries, which make up 10% to 42% of collateral ligament injuries of the thumb. The RCL is especially important for pinch movements and for movements of depression.

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.

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.

The collateral ligaments, UCL, and radial collateral ligament (RCL) (Fig. 1), provide stability against valgus and varus stress, respectively. The UCL, a proper collateral ligament, is the chief restraint to valgus stress during MCP joint flexion 4 and an accessory collateral ligament 5, which along with the volar plate serves as the primary ...

The Radial Collateral Ligament (RCL) is similar to the UCL, but is on the opposite side of the UCL (on the outside part of the thumb). Most of what is described below pertains to both the UCL and the RCL. Injury to the ligament occurs when there is a sudden force on the thumb, such as falling or having the thumb pulled away.

Instruct the patient to begin active range of motion exercises of the thumb without stressing the UCL/RCL repair. Educate the patient on anti‐edema management. This includes, but not limited to, self-retrograde massage, cold therapy, and extremity elevation. The anti‐edema management will continue for several weeks.
