The tendon that straightens the end of the finger attaches to a small piece of bone on the top of the DIP (end joint near the fingernail) joint. With forceful flexion or a crushing injury, the tendon may be torn or it may actually pull away from its attachment to the bone. Sometimes a small piece of bone breaks off when the tendon is forcefully disrupted. If left untreated, what seems a minor problem can end up a long term deformity that is not easily corrected with therapy or even surgery. The best treatment for a Mallet Finger is early treatment with appropriate splinting or casting. It is recommended to see a doctor to ensure correct treatment.
A Mallet Finger, sometimes called a “baseball finger” is a condition in which the end joint (the DIP joint) of a finger bends but will not straighten by itself. The finger can be pushed into a straight position but it will not stay straight without support.
The standard treatment for a Mallet Finger is to immobilize it in a straight position full time for 4 to 6 weeks. Oval-8 Finger Splints from 3-Point can be used on the DIP joint to hold it in extension while still allowing the middle joint (PIP joint) to bend. One or two splints can be used to hold the DIP joint in a straight position. Oval-8 splints are easy to wear and can be worn full time until the finger heals or further treatment is recommended. The Oval-8 splints must be fit and adjusted by a health care professional to assure proper positioning of the finger.
