When is splinting recommended for mallet finger?

Mallet finger, also called baseball finger, affects the tendon that straightens the end joint of a finger. The fingertip may droop when the hand is relaxed, while passive straightening may still be possible. A splint holds the end joint in a straight or slightly extended position so the tendon ends are not repeatedly pulled apart during healing.

An examination can help distinguish a tendon injury from a small fracture or a joint problem. The recommended splint design and wearing schedule depend on the injury and the clinician’s assessment.

Arrange an assessment after a new drooping fingertip or an injury at the end of the finger. If splinting is prescribed, keep the end joint supported exactly as instructed. Removing it carelessly can let the fingertip bend and interrupt healing; a clinician can show you how to change or clean it while keeping the joint straight.

Keep the skin dry and check for rubbing, numbness, colour change, swelling, or worsening pain. Do not force the fingertip straight or return to activities that repeatedly strike or bend it until you have advice.

Seek prompt medical care if the finger is visibly deformed, numb, pale or blue, severely swollen, or cut, or if the fingertip cannot be moved after a significant injury. Contact the clinician managing the splint if the skin breaks down, the splint no longer holds the joint straight, or the droop returns.

Ask whether the injury involves the tendon, bone, or both; which splint is suitable; how to protect the joint during washing; and what changes should trigger an earlier review.
