Mallet Finger Exercises: Rehabilitate Your Drooping Fingertip

Mallet finger occurs when the extensor tendon at the fingertip is torn or pulled off the bone, causing the end of the finger to droop. This common injury happens when something strikes the tip of an extended finger—catching a ball, tucking in sheets, or hitting a finger on a hard surface. Proper treatment and rehabilitation are essential to restore normal fingertip extension.

Understanding Mallet Finger

Anatomy

The extensor tendon runs along the top of the finger and attaches to the distal phalanx (fingertip bone). This tendon allows you to straighten the distal interphalangeal (DIP) joint—the last joint of the finger.

Types of Mallet Finger

• Tendon rupture: Tendon tears without bone involvement
• Bony mallet: Small piece of bone pulled off with tendon (avulsion fracture)

Why Splinting Comes First

Critical: Mallet finger requires 6-8 weeks of continuous splinting BEFORE exercises begin. The DIP joint must be kept in full extension 24/7 to allow the tendon to heal.

If you remove the splint during this period, even briefly, the healing tendon can rupture and healing restarts from day one.

This guide covers exercises for AFTER the splinting period.

Phase 1: Immediate Post-Splint (Week 6-8)

Goals

• Begin protected motion
• Maintain DIP extension
• Prevent joint stiffness
• Monitor for extensor lag

When to Start Exercises

Begin ONLY when:

• Your healthcare provider clears you
• Mandatory splinting period is complete (6-8 weeks)
• No extension lag at DIP joint (or lag is accepted as final result)

Continued Night Splinting

Most protocols recommend:

• Remove splint for exercises during day
• Continue wearing splint at night for 2-4 more weeks
• Splint during activities with injury risk

Passive DIP Flexion

Start with gentle passive motion:

1. Use opposite hand to support injured finger
2. Keep middle joint (PIP) straight
3. Gently bend DIP joint with other hand
4. Only go to point of mild resistance
5. Return to straight position

Perform: 10-15 reps, 4-6 times daily

Active DIP Extension

1. Support finger with other hand
2. Actively straighten DIP joint
3. If you cannot fully extend, that's your starting point
4. Hold straight position 3-5 seconds

Perform: 10-15 reps, 4-6 times daily

DIP Blocking Exercise

Focus extension strength:

1. Hold middle of injured finger with other hand
2. Bend DIP joint slightly
3. Straighten DIP against the resistance of your holding hand
4. Don't let PIP joint move

Perform: 10 reps, 3-4 times daily

Tendon Gliding Exercises

Keep all finger tendons mobile:

Straight Position: All joints straight Hook Position: Bend DIP and PIP, keep knuckle straight Full Fist: Bend all joints Tabletop: Bend knuckles, keep fingers straight

Perform: 5 cycles through all positions, 3-4 times daily

Phase 2: Progressive Motion (Week 8-10)

Goals

• Increase DIP flexion range
• Maintain extension strength
• Improve finger function
• Resume light activities

Active DIP Flexion

Progress from passive to active:

1. Support finger at middle joint
2. Actively bend DIP joint
3. Straighten actively
4. Increase range as tolerated

Perform: 15-20 reps, 4 times daily

Composite Finger Flexion

Full finger motion:

1. Start with finger straight
2. Make a full fist, bending all joints
3. Focus on DIP joint bending
4. Straighten completely

Perform: 15-20 reps, 3-4 times daily

PIP-DIP Coordination

Isolate joint movement:

1. Hold finger at knuckle joint
2. Bend both PIP and DIP together
3. Straighten both together
4. Then try alternating: bend PIP while straightening DIP, vice versa

Perform: 10-15 reps of each, 3 times daily

Table Slides

1. Place hand flat on table
2. Slide fingertips toward palm, keeping fingertips on table
3. This bends DIPs while keeping fingers relatively straight
4. Return to flat position

Perform: 15-20 reps, 3 times daily

Putty Exercises (Light Resistance)

Use soft therapy putty:

Pinching:

1. Pinch putty between thumb and injured fingertip
2. Focus on DIP joint engagement
3. Release and repeat

Perform: 15-20 pinches, 2-3 sets

Phase 3: Strengthening (Week 10-12)

Goals

• Build grip and pinch strength
• Full functional range
• Return to normal activities
• Prevent re-injury

Finger Walks on Putty

1. Press fingertips into putty
2. "Walk" fingers forward through putty
3. Focus on DIP flexion and extension

Perform: Walk across putty 5-10 times, 2-3 sets

Pinch Strengthening

Tip Pinch:

1. Pinch small object between thumb and fingertip
2. Hold 5 seconds
3. Progress to heavier objects or resistance

Key Pinch:

1. Hold object between thumb and side of index finger
2. Include injured finger if applicable

Perform: 10-15 reps each type, 3 sets

Grip Strengthening

1. Squeeze stress ball or hand gripper
2. Focus on full finger engagement
3. Include DIP flexion in the squeeze

Perform: 15-20 squeezes, 3 sets

Rubber Band Extensions

1. Place rubber band around all fingertips
2. Spread fingers apart against resistance
3. Focus on straightening DIP joints

Perform: 15-20 reps, 3 sets

Finger Lifts

1. Place hand flat on table
2. Lift injured finger off table
3. Keep other fingers down
4. Hold 3-5 seconds

Perform: 10-15 reps, 3 sets

Resistance Band DIP Work

1. Loop small band around fingertip
2. Anchor other end
3. Bend and straighten DIP against resistance

Perform: 15-20 reps, 2-3 sets

Phase 4: Functional Activities (Week 12+)

Goals

• Full return to activities
• Sport or occupation-specific function
• Maintain gains
• Prevent re-injury

Functional Tasks

Practice real-world movements:

• Typing
• Writing
• Buttoning clothes
• Picking up small objects
• Cooking tasks

Sport-Specific Training

Ball Handling:

• Start with soft balls
• Progress to regular equipment
• Practice catching with injured finger included

Instrument Playing:

• Begin with simple exercises
• Progress to normal playing
• Monitor for fatigue

Occupation-Specific

Gradually return to:

• Fine motor work
• Typing or computer work
• Manual tasks
• Any fingertip-intensive activities

Important Considerations

Extension Lag

Some people have permanent mild extension lag (fingertip doesn't fully straighten):

• Up to 10-15 degrees may be acceptable
• Usually doesn't affect function significantly
• Surgery may be considered for larger lags if functional problem

Signs of Problems

Seek evaluation if:

• Extension lag worsens during exercise phase
• Significant pain develops
• Finger becomes swollen or red
• DIP joint becomes unstable

Bony Mallet Considerations

If you had a bony mallet (avulsion fracture):

• May have longer splinting period
• X-ray may be needed to confirm healing
• Same exercise progression once cleared

Swan Neck Deformity

Long-term complication where:

• PIP joint hyperextends
• DIP joint remains flexed
• Can develop if mallet finger not properly treated
• May require hand therapy or surgery

Exercises to Avoid

During Splinting:

• ALL exercises to injured finger (splint stays on)
• Anything requiring DIP flexion

Early Post-Splint:

• Forceful gripping
• Sports involving ball catching
• Heavy lifting
• Any activity risking re-injury

Throughout Recovery:

• Aggressive stretching into flexion
• Any exercise causing pain
• Activities before cleared by provider

Sample Schedule (Post-Splint Week 6-8)

Multiple Times Daily

Every 2-3 hours:

• Passive DIP flexion: 10-15 reps
• Active DIP extension: 10-15 reps
• Tendon gliding: 5 cycles

Morning and Evening:

• DIP blocking: 10 reps
• Composite finger motion: 15 reps

Night

• Continue wearing splint

Sample Schedule (Week 10+)

Morning

• Finger ROM: All positions
• Putty exercises: 2-3 minutes
• Pinch strengthening: 3x10

Afternoon

• Finger lifts: 3x10
• Rubber band extensions: 3x15
• Functional practice

Evening

• Full ROM exercises
• Grip strengthening: 3x15
• Light stretching

Prevention After Recovery

Protect Your Finger

• Be aware of activities that could re-injure
• Consider taping for sports
• Avoid catching hard objects with fingertips

Maintain Strength

• Continue grip and pinch exercises
• Include finger exercises in regular routine
• Monitor for any extension loss

Key Takeaways

Mallet finger recovery requires patience:

1. Splint first - 6-8 weeks of continuous splinting before exercises
2. Don't remove splint early - Even briefly can disrupt healing
3. Start motion gently - Progress gradually from passive to active
4. Expect some lag - Small extension lag is common and usually acceptable
5. Continue night splinting - 2-4 weeks after starting exercises

Most mallet fingers heal well with proper splinting and rehabilitation. The biggest mistake is removing the splint too early or being too aggressive with exercises. Trust the process and protect your healing tendon.
