Understanding and Treating Mallet Finger Injuries
Mallet finger injuries occur when the tendon that straightens the fingertip is disrupted, often due to forced flexion, such as when a ball strikes the tip of the finger. Surprisingly, it can also happen during everyday activities like pulling on socks or tucking in bed sheets.
Types of Mallet Finger Injuries
- Soft Tissue Mallet Injuries: These involve a tear in the terminal extensor tendon.
- Bony Mallet Injuries: These occur when a piece of bone breaks away where the tendon inserts.
Symptoms
- “Droopy finger”: The fingertip cannot be fully extended on its own.
- Swelling, tenderness, and redness, particularly at the back of the tip joint.
- Sometimes pain-free, making it confusing as to why the fingertip won’t straighten.
Importance of Proper Diagnosis
Identifying the type of mallet injury is crucial. Certain bony mallet injuries, where the bony fragment is large, may require surgical intervention to stabilize the joint.
Treatment
- Splinting: Continuous splinting of the injured joint for 6-8 weeks (up to 10 weeks in some cases) to allow for proper healing.
- Post-Splinting Therapy: Gradual weaning from the splint and performing exercises to regain motion and prevent recurrence of the “droop” or finger lag.
Risks of Untreated Mallet Finger
Ignoring a mallet finger can lead to imbalances in the finger, resulting in further complications such as a swan neck deformity, where the middle knuckle (PIPJ) hyperextends while the fingertip droops.
Why Early Treatment Matters
Mallet injuries have better outcomes when treated promptly. Delaying treatment can result in a chronic droop that may be irreversible.
