What is the Lateral Ulnar Collateral Ligament (LUCL)? 

A ligament is a band of elastic, tough fibrous connective tissue around a joint. It attaches bone to bone, supports and holds them together and limits the joint's movement.

Your elbow is made of four ligaments. The ligament on the outside of the elbow is a lateral ulnar collateral ligament (LUCL). It is the main one of the four ligaments that make up the lateral collateral complex of the elbow.

A LUCL injury is a condition where the ligament is extremely stretched or torn and detached from the elbow joint.

Causes of LUCL Injuries

LUCL injuries are mostly caused by looseness of the ligament due to traumatic dislocation in the elbow joint. Insufficiency of the lateral elbow collateral ligament complex can also lead to LUCL injury.

Symptoms 

Pain in the elbow is the primary symptom of LUCL injuries. Other symptoms can be:

  • A sensation of the elbow sliding out of place
  • A feeling of clicking with elbow extension
  • Clunking or catching when pushing off from a chair arm

Diagnosis 

LUCL injuries are typically diagnosed using various methods such as:

  • Physical exam with palpation (check for tenderness over LUCL) 
  • Motion and stability in the elbow (varus instability)
  • Provocative test and apprehension test
  • Chair rise test, floor push-up test, table-top relocation test
  • Radiograph (X-ray) test or MRI test

What are the Nonoperative Options?

Physiotherapy to strengthen the muscles around the elbow can be the first nonoperative option. Additionally, your doctor may also consider other options such as:

  • Immobilisation at 90° flexion for 5 to 7 days
  • Bracing, extensor strengthening
  • Activity modifications

What are the Operative Options?

The operative options include:

  • LUCL repair and fixation by surgery
  • LUCL reconstruction (allograft or autograft)
  • Palmaris longus tendon graft
  • Docking technique

However, these procedures may sometimes lead to complications such as recurrent instability (3-8% occurrence), infection, cutaneous nerve injury, and decreased ROM.

What Happens After Your Surgery?

After the surgery, your elbow will be put into a splint for 7-10 days.

Your Rehabilitation

Once the splint is removed, your rehabilitation process begins with a controlled motion of the elbow. A removable thermoplastic splint is likely to be applied for 3 more weeks to facilitate the overhead range of motion (ROM) exercises in the supine position.

Thereafter, the focus will be shifted toward strengthening the elbow flexors, extensors, pronators, and supinators. The rehabilitation process may continue until you resume full activity, which will usually take 4 to 6 months after your surgery.
