Mallet Finger Treatment in Raleigh, NC
Did a ball strike your fingertip, or did you catch your finger on something? A drooping fingertip you cannot straighten is mallet finger. The good news: most cases heal completely with a splint — no surgery needed.
What Is Mallet Finger?
Mallet finger occurs when the extensor tendon at the fingertip is ruptured — either as a pure tendon tear (soft-tissue mallet) or with a bone fragment pulled away (bony mallet). The result is a drooping DIP joint the patient cannot actively straighten.
It classically occurs when a ball hits an outstretched fingertip, forcing it into sudden flexion. It can affect any finger but most commonly the ring, long, or little finger. Children may also sustain mallet finger — often treated the same way.
ⓘ The #1 rule of mallet finger treatment: the finger must stay straight 24 hours a day for 6–8 weeks. Even a single momentary bend resets the entire healing clock.
Risk Factors
Several factors are associated with a higher likelihood of developing this condition.
Ball Sports
Baseball, basketball, volleyball
Football
Pass reception or blocking
Gymnastics
Landing and tumbling falls
Stub Injury
Catching on clothing or bedding
Work Injury
Tool-related fingertip force
Any Age
Occurs across all age groups including children
Stages of Mallet Finger
Pure tendon rupture — no fracture. Treated with splinting alone.
Small bone fragment — usually treated the same way as soft-tissue mallet.
Large fragment or joint subluxation — may require surgical fixation.
Diagnosis
Mallet finger is diagnosed clinically by examining whether the patient can actively extend the DIP joint, confirmed with X-rays to determine if a bone fragment is present and assess joint congruency. The lateral X-ray view is critical.
- ✓Active DIP extension test — can patient straighten the tip?
- ✓X-rays (AP and lateral — lateral is most important)
- ✓Fragment size as percentage of joint surface
- ✓Joint congruency — does the joint sublux?
- ✓Assessment of PIP joint (sometimes involved)
Treatment Outcomes & Statistics
Published outcome data to help you make an informed decision. Dr. Chambers will review what these numbers mean for your specific case at your visit.
Soft-tissue and small bony mallets achieve full or near-full extension with splint alone
With strict 24/7 compliance — finger must never flex during the splinting period
Continuous — not removable. Even washing hands requires keeping the tip dry and straight
Only for large fragments (>30% joint) with joint subluxation
Complication Profile
| Complication | Rate | Severity | Notes |
|---|---|---|---|
| Minor extensor lag (5–10°) | 10–20% | Minor | Usually functionally insignificant; common finding |
| Skin maceration under splint | Common | Minor | Skin checks every 1–2 weeks; skin care important |
| Pin-site infection (surgical cases) | 5–10% | Moderate | Monitored and treated promptly |
| Persistent lag / poor extension | 5–10% | Moderate | Often from non-compliance with splinting |

Treatment Options
Dr. Chambers will recommend the best approach based on your severity, goals, and lifestyle. Most conditions are first treated non-surgically.
Continuous Extension Splinting
A small splint holds the DIP joint in full extension for 6–8 weeks without ANY interruption. The tendon heals across the gap. Critical rule: the tip must never droop — even once — during the entire splinting period. Stack splints, thermoplastic custom splints, and prefabricated aluminum splints are all options.
Surgical Fixation
For large bony fragments (>30% of joint surface) with joint subluxation, a pin or screw holds the fragment in place. Required when the joint is no longer congruent on X-ray. Outpatient procedure under local anesthesia.
What to Expect During Recovery
Continuous Splinting
DIP joint in full extension 24/7. PIP joint left free. Skin inspected every 1–2 weeks. No bending under any circumstances.
Weaning Phase
Begin removing splint for short periods during the day. Continue night splinting for 4–6 additional weeks.
Consolidation
Daytime splint discontinued. Night splint continues. Gentle DIP range-of-motion exercises begin.
Full Recovery
Full extension typically maintained. Some patients retain a minor lag of 1–5° — usually not noticeable in daily life.
Frequently Asked Questions
The great majority of mallet fingers — about 85–95% — are treated very successfully with splinting alone. Surgery is reserved for fractures involving more than 30% of the joint surface or when the joint shifts (subluxes) on X-ray. Dr. Chambers will review your X-rays and give you a clear recommendation.
Even a single moment of the fingertip bending during the healing period fully restarts the 6–8 week clock. This is the most critical point about mallet finger treatment. The splint must be worn continuously — even when washing hands (dry one hand at a time while keeping the tip straight).
Most patients achieve full or near-full extension. A minor extensor lag of 5–10° may persist but is usually not noticeable during daily activities and causes no pain. Strict compliance with splinting is the strongest predictor of outcome.
Keeping the DIP joint extended is the priority — even during hand washing. When washing your hand, keep the splinted fingertip elevated and dry it carefully with a cloth. A spare splint allows you to switch while washing. Dr. Chambers will give you detailed instructions at your visit.
