Ulnar collateral ligament (UCL) injuries of the elbow joint have become common among overhead throwing athletes, particularly baseball pitchers. Recent studies reported the failure of nonoperative management of UCL injury in overhead athletes. On the contrary, UCL reconstructions in baseball players have been proven to be an effective procedure for...
The elbow jointis stabilized primarily by three ligaments: 1. Medial collateral ligament 2. Lateral collateral ligament 3. Annular ligament The medial and lateral collateral ligaments provide valgus and varus stability, and allow for rotation. The annular ligament encircles the head of the radius, stabilizing it in the radial notch. Each of these l...
Lateral collateral ligamentous injuries are typically associated with fracture or dislocation(shown below). Medial collateral ligamentous injuries are typically caused by overuse. Some common causes of elbow ligamentous injuries include: 1. Forced twisting of the arm 2. Falling on an outstretched arm 3. Repeated overhead movement (such as in pitchi...
Although ligamentous injuries are rare, patients may present with varus or valgus laxity due to overuse or trauma. Lateral Collateral Ligament injury is often associated with trauma and forceful motion into varus. These injuries are commonly associated with a fracture or subluxation at the elbow joint. An Ulnar Collateral Ligament tear or sprain co...
Modified Milking Maneuver, tests for UCL sprain or tear from overuse.Three common patient reported outcome measures are used for elbow ligamentous injuries: 1. The DASHis 30 questions scored from 0-100, 0 meaning no disability. The DASH is well studied and validated with a minimally clinical important difference or MCID of 15 point or MCD of 12.7 points. 2. The Quick DASH, commonly used in place of The DASH. The pat...
Due to lack of high quality literature for these conditions, it is recommended that an impairment-based approach be used to guide management. 1. Nonsteroidal anti-inflammatory drugs (NSAIDs) are commonly used for relief of pain and inflammation. If pain is severe, a mild narcotic or corticosteroid injections may be prescribed. 2. Common impairments...
Malignancy: Severe progressive pain that is not affected by movementInflammatory Arthrithides: Abnormal systemic signsFracture: History of trauma, Elbow Extension Test(specificity: 0.69, sensitivity: 0.97), marked limitations in range of motion and ecchymosisRehabilitation following elbow injury or elbow surgery follows a sequential and progressive multiphased approach. The phases of the rehabilitation program should overlap to ensure proper progression. The ultimate goal of elbow rehabilitation is to return the athlete to his or her previous functional level as quickly and safely as possible. 1. Phase...
Apr 3, 2019 · Lateral collateral ligament complex. On the lateral side of the elbow joint, the LCL complex is comprised of three primary structures: the radial collateral ligament proper (RCL), the annular ligament (AL), and the lateral ulnar collateral ligament (LUCL) (Fig. 4 b).

Jul 31, 2023 · The elbow is a hinge joint comprised of bony and ligamentous stabilizers. Specifically, the elbow contains two collateral ligaments: the medial collateral ligament (MCL, also known as ulnar collateral ligament, or UCL) and the lateral collateral ligament (LCL).

Nov 14, 2021 · Learn about the anatomy, function and pathology of the lateral ulnar collateral ligament (LUCL), a part of the lateral collateral ligament complex of the elbow. The LUCL is a primary stabilizer of the elbow joint to varus and external rotatory stress.

The lateral collateral ligament (LCL) of the elbow is the ligament on the outside of the elbow, not to be confused with the LCL in the knee. The LCL in the elbow is sometimes also called the radial collateral ligament (RCL). This ligament can become sprained or torn as a result of a sports injury.
The lateral collateral ligament stabilizes the humerus to the annular ligament and to the proximal ulna, thereby maintaining the relationship of the proximal forearm to the trochlea and capitellum. Lateral collateral ligament insufficiency is more rare and not associated with specific activities.
