The main idea here is that healing of the torn extensor mechanism at the distal interphalangeal joint requires the DIP to be held in full extension for a prolonged period. Mallet finger is an injury where the terminal extensor tendon (or a bony avulsion at the distal phalanx) cannot adequately straighten the fingertip. Keeping the DIP in full extension with a splint for about six weeks provides the proper position for the tendon or bone fragment to reattach and heal without being strained by flexion. After this period, gradual weaning from the splint is usually done to restore function.

Other approaches don’t deliver the same stable extension position for the necessary duration: a night splint for only a short time won’t maintain extension long enough for healing; casting in neutral doesn’t lock the DIP in the required extended position; and surgical repair is considered when there is a large bony fragment or joint incongruity, not for standard nonoperative care.
