What is the recommended treatment for non-bony mallet finger?

The recommended treatment for non-bony mallet finger is to apply a splint in full extension for a duration of 6 to 8 weeks. This approach is crucial because the primary goal in managing non-bony mallet finger is to stabilize the distal interphalangeal (DIP) joint and allow the damaged extensor tendon to heal without any further movement that could hinder recovery.

By keeping the finger in full extension with a splint, it prevents flexion at the injured joint, which is necessary for proper alignment and healing of the tendon. This method helps restore normal function and minimizes the risk of developing a permanent flexion deformity.

While other treatments like surgery (for more severe cases or bony involvement) and conservative measures such as rest, ice, and pain relief could be referenced, they do not provide the focused management that is specifically effective for non-bony mallet finger. Thus, the full extension splinting is the cornerstone of treatment for this injury.
