Finger Sprain

Finger Sprain



Description


Finger sprain results from violent overstretching and tearing of one or more ligaments that hold the finger joints together. Sprains involving two or more ligaments cause more disability than a single-ligament sprain. 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, or a portion of the ligament is ruptured; it still functions, but there is some loss of function. With a third-degree sprain, the ligament is torn (complete rupture) and does not function. Severe sprains occasionally require surgery.



Common signs and symptoms



• Severe pain at the time of injury

• A feeling of popping or tearing inside one or more fingers

• Tenderness, swelling, and later bruising in the finger

• Impaired ability to use the injured finger


Causes


Finger sprain is caused by stress on a ligament that temporarily forces or twists finger joints out of their normal location. The ligaments that normally hold the joint in place are stretched or torn.



Factors that increase risk



• Previous finger sprain or injury

• Contact sports and sports that involve catching and throwing, such as baseball, basketball, and football

• Poor physical conditioning (strength, flexibility)

• Inadequate or poorly fitting protective equipment


Preventive measures


Taping, protective strapping, bracing, and splints may help prevent injury.



Expected outcome


If this is a first-time injury, proper care and sufficient healing time before resuming activity should prevent permanent disability. Ligaments have poor blood supply and when torn, they require as much healing time as fractures. Average healing time for a first-degree sprain is 2 to 6 weeks, a second-degree sprain takes up to 8 to 12 weeks to heal, and a third-degree sprain takes up to 12 to 16 weeks, although swelling of the finger may last up to a year.
