An Overview of Tommy John Surgery from a Phoenix Orthopedic

by / Monday, 05 January 2015 / Published in Elbow Surgery

Tommy John surgery involves repair of an injured elbow ligament. The surgery is named after Tommy John, a former Los Angeles Dodgers pitcher who had the first procedure of this kind in 1974. Often called ulnar collateral ligament (UCL) reconstruction, Tommy John surgery is done to repair the injured UCL elbow ligament following an injury, which often occurs in college or professional baseball pitchers.

TOMMY-JOHN2In 1974, when Dr. Frank Jobe performed the first UCL reconstruction, a torn UCL was considered to be a career-ending injury. Now, however, more than 85% of patients who have Tommy John surgery are able to resume their sport at their previous activity level.

Causes of UCL Injury

The UCL is located on the inner portion of the elbow. This ligament connects the upper arm bone (humerus) to the forearm bone (ulna). Baseball pitchers and athletes who are throwers have the greatest risk for a UCL tear or injury. This is due to repetitive throwing motions that bend and twist the elbow, putting extreme stress on the elbow ligament. Over time, the ligament develops tiny tears, or a large tear can occur at any point.

Athletes at Risk for UCL Tears

As the ligament stretches and lengthens with repetitive throwing, it can no longer hold the bones tightly enough. Sports that can lead to UCL tears and injuries include:

  • BaseballUCL Anatomy
  • Tennis
  • Javelin throw
  • Soccer
  • Football
  • Softball
  • Cheerleading
  • Wrestling

Symptoms and Diagnosis of a UCL Injury

The diagnosis of a UCL injury is made through a history and physical examination. However, diagnostic tests are used to confirm the diagnosis. The magnetic resonance imaging (MRI) scan shows the extent of the ligament tear and injury.

  • Pain on the inner aspect of the elbow
  • Decreased throwing ability
  • A feeling of instability or looseness of the elbow
  • Irritation of the funny bone (ulnar nerve), felt as numbness or tingling in the fingers
  • Inability to lift or perform activities of daily living

Tommy John Surgery for UCL Injury

UCL RepairWith serious UCL injury, Tommy John surgery is done. The Scottsdale sports medicine surgeon takes a tendon from another area in the body, such as the hamstring or Achilles tendon. Small incisions are made around the elbow region.

With the arthroscopic technique, a small camera is inserted through incisions so the doctor can visualize the structures on a TV monitor. The surgeon removes any lose bodies and bone spurs, shaves the damaged UCL, and replaces the ligament along the medial side with a tendon graft.

The graft is fitted into tunnels drilled in the ulna and humerus. One common technique for replacing the damaged UCL is called the docking technique. With this, the surgeon drills two holes in the ulna and three holes in the end portion of the humerus, on the inner aspect. Remnants of the original ligament are also attached with the grafted tendon. After the repair, the incisions are closed with sutures and the arm is immobilized.

Tommy John Surgery Rehabilitation

For some UCL tears, recover takes only 6 months to a year. However, for severe injuries, it can take up to 2 years for the athlete to return to previous level of ability. Closely monitored by the patient’s surgeon and a physical therapist, rehabilitation occurs in three phases:Tommy-John

  • Phase I – Immediately after surgery (0 to 6 weeks): The patient wears a splint for 7 to 10 days, and does gentle range of motion and strengthening exercises.
  • Phase II – Six weeks after surgery: Begin to perform elbow-strengthening exercises, and avoids activities that stress the graft.
  • Phase II – Around 4 to 5 months after surgery: Athletes toss a ball and begin easy wind-up with throwing. The athlete can start to pitch after around 9 to 12 months.
