A 15-year-old athlete has pain and inability to extend the distal phalanx after an injury. What is the treatment of choice?

The presentation describes a situation likely involving an injury referred to as a mallet finger, where there is an inability to extend the distal phalanx following trauma. This condition arises when the extensor tendon is injured or avulsed, preventing extension at the distal interphalangeal (DIP) joint.

The treatment of choice in this case, which is continuous extension of the DIP joint with splinting, is crucial for proper healing. The goal is to maintain the distal phalanx in an extended position, which helps to allow the tendon to heal properly and reattach if it is avulsion-related. This is typically achieved through the use of a specific splint that keeps the joint in the recommended extended position over the course of several weeks. Proper alignment and immobilization are key to restoring function and preventing long-term disability.

Maintaining the joint in this position prevents the tendon from shortening and allows for proper functional recovery. It is important to adhere to this treatment to ensure the best possible outcome for the athlete's hand function following such an injury.
