The median extensor tendon is a strong fibrous cord that attaches to the top of the middle phalanx of the finger and is responsible for extending the finger. A middle finger extensor tendon injury occurs when this tendon is partially or completely torn.
These injuries can be caused by a sudden forceful impact, such as a fall or direct blow to the finger, or by repetitive overuse, such as in activities that involve gripping or repetitive finger motion. Common symptoms of a central slip extensor tendon injury include pain, swelling, stiffness, and difficulty extending the finger.
Treatment of central extensor tendon injuries includes rest, immobilization with a splint or cast, physical therapy, and medications to treat pain and inflammation. In severe cases, surgery may be required to repair or rebuild the tendon.
It is important to see a doctor if you suspect a central extensor tendon injury. Prompt treatment can prevent further damage and improve outcomes.
