What is the standard treatment for an avulsion fracture associated with mallet finger?

The standard treatment for an avulsion fracture associated with mallet finger is to use a stack splint for 8 weeks. Mallet finger occurs when a tendon that straightens the end joint of a finger is injured, usually accompanied by a fracture of the distal phalanx. The stack splint is specifically designed to keep the finger in a straight position while allowing the tendon to heal properly. Proper alignment and immobilization are crucial in preventing any permanent loss of function and ensuring that the tendon heals correctly.

The duration of 8 weeks is also important because it typically allows enough time for the associated structures to heal effectively. During this period, maintaining the proper position of the finger is essential for optimal recovery. While buddy taping may provide some support, it does not offer the same degree of immobilization and may not be sufficient for an avulsion fracture. Surgical fixation is generally considered only if there is significant displacement or if conservative treatment fails, and immediate therapy intervention is not the standard approach for this specific injury, as initial management focuses on immobilization.
