Ulnar Collateral Ligament Injury of the Thumb
From Shankman GA: Fundamental Orthopaedic Management for
the Physical Therapy Assistant. St. Louis, Mosby Year Book, 1997, p. 291
Description
Ulnar collateral ligament injury of the thumb involves stretching and tearing of
a ligament at the base of the thumb (ulnar collateral ligament [UCL]). This
ligament is important in the function of the thumb, particularly when you grab,
grasp, or pinch (such as when holding your keys). Sprains are classified into
three grades. In a first-degree sprain, the ligament is not lengthened but is
painful. With a second-degree sprain, the ligament is stretched and painful but
still functions. With a third-degree sprain, the ligament is torn and does not
function.
Common Signs and Symptoms
-
Pain, tenderness, bruising, swelling and redness at the base of the thumb, starting at the side of injury, that may progress to the whole thumb and even hand with time
-
Impaired ability to grasp or hold things soon after injury
Treatment Considerations
Initial treatment consists of ice to relieve the pain and compressive elastic
bandaging and elevation to help reduce swelling and discomfort. A brace or cast
may be recommended to provide support to the joint for varying times, depending
on severity of injury. For complete tears of the ligament, surgery is often
recommended because other tissues may become entrapped between the ends of the
ligament, preventing healing.
RICE Principle
With all acute injuries, follow the RICE principle to reduce swelling, pain and inflammation.
-
Rest- Use that hand sparingly if possible.
-
Ice- Use an ice pack for 20 minutes every two to three hours during the first 72 hours.
-
Compression- Use an ace wrap if needed. Start at the top of the thumb and then wrap around the hand and wrist.
-
Elevation- Keep the injured hand above the level of the heart when you are sitting or lying down
