What is RCL injury?
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.
What is RCL ligament?
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 to outer stress on the elbow.
What is the RCL in the wrist?
The radial collateral ligament (RCL) is located at the thumb side of the wrist and originates at the outer edge of the radius on a small bump called the radial styloid. It connects at the side of the scaphoid and prevents the wrist from bending too far to the side opposing the thumb.
How painful is a torn thumb UCL?
This injury is sometimes called “skier’s thumb” because skiers are prone to this injury when they fall with their hand strapped to a ski pole. A thumb UCL injury can be very painful and make the thumb feel unstable. The injury can limit movements, such as squeezing and gripping, needed for many sports.
How do you treat a torn UCL thumb?
How are UCL injuries treated? Partial tears and minimally displaced tears can be treated in a cast, which is worn for four weeks followed by a removable splint until motion and stability are returned. Complete tears that are displaced are treated surgically.
Where does the RCL attach?
The radial collateral ligament attaches at one end to the lateral epicondyle of the humerus and at the other end attaches to the lateral part of the annular ligament, the radius and also the ulnar.
How do you tell if you have a torn ligament in thumb?
Symptoms
- Pain and severe swelling on the inner part of the thumb immediately after the injury.
- Pain and severe swelling on the base of the thumb immediately, or shortly after the injury.
- Weakness and instability during grasp or writing.
- Loss of motion when attempting to move the thumb circular.
Where is the radioulnar ligament?
The palmar radioulnar ligament (volar radioulnar ligament, anterior radioulnar ligament) is a narrow band of fibers extending from the anterior margin of the ulnar notch of the radius to the front of the head of the ulna. It is sometimes abbreviated PRUL.
Where is the radioulnar joint?
forearm
The radioulnar joints are two joints between the two bones of the forearm: the ulna, on the medial side, and the radius, on the lateral side. There’s one superior, or proximal radioulnar joint, and one inferior, or distal radioulnar joint, and together they allow for the movements of pronation and supination.
What kind of joint is radioulnar?
Synovial pivot joint
Proximal radioulnar joint
| Type | Synovial pivot joint; uniaxial |
|---|---|
| Articular surfaces | Head of radius, radial fossa of ulna |
| Ligaments | Annular ligament, quadrate ligament |
| Innervation | Median, musculocutaneous, radial and ulnar nerves |
| Blood supply | Deep brachial, radial and common interosseous arteries |
How rare is Radioulnar Synostosis?
Congenital radioulnar synostosis is rare, with only about 350 cases identified worldwide. The average age at diagnosis is about 6 years, which is typically the age when children start attending school and having more physical activity demands.
Do all UCL injuries require surgery?
Treatment for UCL injuries ranges from rest and physical therapy to surgery, depending on the extent of the UCL tear and your health goals.
What is an RCL injury on the thumb?
RCL Injury. Radial collateral ligament injuries occur as a result of a forced adduction moment on the MCP joint of the thumb, which may occur from a fall on the radial aspect of the thumb and hand or during sports when a ball or player strikes the thumb.
What is a UCL rupture of the thumb?
Thumb collateral ligament ruptures, 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.
Can a thumb ligament rupture?
However, in severe type of injuries, both ligaments may be ruptured. Thumb ligament injuries usually occur from a forced radial deviation (abduction) of the thumb during a high-velocity activity. Skiers and those who play ball-handling sports, such as baseball, football and basketball, have a greater risk of sustaining such an injury.
Where do thumb ulnar and radial collateral ligament ruptures occur?
The most frequent rupture site locations that are often cited are the thumb ulnar collateral ligament (UCL) occurring distally from the proximal phalanx and the radial collateral ligament (RCL) occurring proximally from the metacarpal head. 2,16 In this study, we report the frequency of the rupture site location of both thumb UCL and RCL injuries.
