UCL Reconstruction

The UCL, also called medial collateral ligament, is located on the inside of the elbow and connects the ulna bone to the humerus bone. It is one of the main stabilizing ligaments in the elbow especially with overhead activities such as throwing and pitching. When this ligament is injured, it can end a professional athlete’s career unless surgery is performed.

Ulnar collateral ligament (UCL) Reconstruction surgery involves replacing a torn ulnar collateral ligament with a tendon from elsewhere in the body. It is also referred to as Tommy John Surgery.

Symptoms.

The common symptoms associated with a UCL injury are as follows:

Pain on inner side of the elbow

Unstable elbow joint

Numbness in the little finger or ring finger

Decreased performance in activities such as throwing baseballs or other objects

Causes.

Ulnar collateral ligament injury is usually caused by repetitive overhead throwing such as in baseball. The stress of repeated throwing on the elbow causes microscopic tissue tears and inflammation. With continued repetition, eventually the UCL can tear preventing the athlete from throwing with significant speed. If untreated, it can end an athlete’s professional career. UCL injury may also be caused by direct trauma such as with a fall, car accident, or work injury. Other causes include any activity that requires repetitive overhead motion of the arm such as tennis, pitching sports, fencing, and painting.

Diagnosis.

UCL injury should be evaluated by an orthopedic specialist for proper diagnosis and treatment. Your physician will perform the following:

Medical history

Physical examination including a valgus stress test to assess for elbow instability

Other tests such as X-rays and MRI scans may be ordered to confirm the diagnosis.

Treatment.

Your physician will recommend conservative treatment options to treat the symptoms associated with UCL injury unless you are a professional or collegiate athlete. In these cases, if the patient wants to continue in their sport, surgical reconstruction is performed.

Conservative treatment options that are commonly recommended for non-athletes include the following:

Activity restrictions

Orthotics

Ice compression

Medications

Physical therapy

Pulsed ultrasound to increase blood flow to the injured ligament and promote healing

Professional instruction

Procedure.

If conservative treatment options fail to resolve the condition and symptoms persist for 6-12 months, your surgeon may recommend ulnar collateral ligament reconstruction surgery. UCL reconstruction surgery repairs the UCL by reconstructing it with a tendon from the patient’s own body (autograft) or from a deceased donor (allograft). The most frequently used tissue is the palmaris longus tendon in the forearm. The basic steps for UCL reconstruction surgery includes the following:

The surgery is performed in an operating room under regional or general anesthesia

Your surgeon will make an incision over the medial epicondyle area

Care is taken to move muscles, tendons, and nerves out of the way

The donor tendon is harvested from either the forearm or below the knee

Your surgeon drills holes into the ulna and humerus bones

The donor tendon is then inserted through the drilled holes in a figure 8 pattern

The tendon is attached to the bone surfaces with special sutures

The incision is closed and covered with sterile dressings

Finally, a splint is applied with the elbow flexed at 90 degrees.

Post-operative care.

After surgery, your surgeon will give you guidelines to follow, depending on the type of repair performed and the surgeon’s preference. Common post-operative guidelines include:

Elevate your arm above heart level to reduce swelling

Wear an immobilizing splint or cast for 1-3 weeks

Apply ice packs to the surgical area to reduce swelling

Keep the surgical incision clean and dry. Cover the area with plastic wrap when bathing or showering

Physical therapy will be ordered for strengthening and stretching exercises after the removal of the splint or cast

Professional athletes can expect a strenuous strengthening and range of motion rehabilitation program for 6-12 months before returning to their sport

Eating a healthy diet and not smoking will promote healing

Risks and complications.

As with any major surgery there are potential risks involved.

The majority of patients suffer from no complications following UCL Reconstruction surgery, however, complications can occur following elbow surgery and include:

Infection

Limited range of motion

Nerve damage causing numbness, tingling, burning or loss of feeling in the hand and forearm area

Cubital Tunnel Syndrome

Elbow instability

UCL Reconstruction surgery, also called Tommy John Surgery, involves replacing a torn UCL ligament with a tendon taken from elsewhere in the body. Conservative treatment measures may be used to treat the condition but for professional athletes who wish to continue in their sport, surgery is the course of treatment followed by extensive rehabilitation.
