Mallet Finger — Symptoms, Causes & Treatment
Also known as Mallet Finger. Causes, symptoms and how physiotherapy treats Mallet Finger — without surgery or medicines.
Understanding Mallet Finger
Mallet Finger affects people differently, and the right care starts with understanding how it affects you. Its day-to-day impact — on movement, strength, energy and confidence — is where physiotherapy does its work.
Our role in Mallet Finger is practical: protect and rebuild movement and daily function with a plan set after a careful assessment, in coordination with your doctor wherever medical management is involved. No two plans look the same, because no two cases behave the same.
Causes & risk factors of Mallet Finger
What commonly drives it — your assessment pins down which of these apply to you.
More than one possible driver
Mallet Finger can have several contributing factors — a careful history and physical assessment separate them rather than guessing.
Reduced movement and deconditioning
Whatever the trigger, less movement quickly adds weakness and stiffness of its own — usually the most reversible part.
Daily-life load and habits
Work posture, repeated tasks, sleep and stress all shape how a condition behaves day to day.
General health and history
Overall health, previous injuries and existing conditions influence both the picture and the plan — the assessment takes all of it in.
When physiotherapy is the right call
If any of these sound like you, an assessment is the right first step.
- ✓ A new diagnosis of Mallet Finger and you want a clear rehabilitation start point
- ✓ Daily tasks, walking or stairs are getting harder than they used to be
- ✓ Strength, stamina or balance has visibly dropped
- ✓ You want a structured clinic + home program with measurable milestones
- ✓ Family members need guidance to support you safely
Your treatment journey
Step by step — from your first assessment to a tracked recovery plan.
A detailed first assessment
History, movement testing and strength checks — a focused session to find what is actually driving your Mallet Finger.
A diagnosis you understand
Your physiotherapist explains the findings in plain language — what is affected, why it happened and what that means for you.
Active, tracked treatment
Hands-on therapy, the right modalities and graded exercise — progressed session by session and tracked on Fizo IQ™.
Prevention, built in
The final phase rebuilds strength and habits so the same problem does not come back — with a home plan you keep.
What recovery looks like
- ✓ More independence in daily tasks
- ✓ Better strength, balance and stamina
- ✓ Fewer setbacks, with red flags monitored
- ✓ A program your family understands and can support
- ✓ Progress measured milestone by milestone on Fizo IQ™

Mallet finger injury also known as “baseball finger,” is a partial or complete tear of the extensor tendon that straightens the end joint i.e. distal interphalangeal (DIP) joint of the finger. The tendon might pull off a small fragment of bone attached at the dorsal base of the distal phalanx with resultant flexed deformity of the distal interphalangeal (DIP) joint.
The mallet finger is usually associated with sports injury or sudden force in the finger:
- Forced flexion of the extended DIP joint.
- Catching the finger when tucking in something.
- Associated with catching a ball.
- In players like baseball catchers, fielders, football receivers, cricketers, and basketball players.
The patient is not able to completely straighten the finger, other symptoms of mallet finger are given below:
- Pain at the dorsum of the DIP.
- Inability to actively extend the DIP joint.
- Swelling around the DIP joint
- Bruising
- Finger stiffness.
- Weak active extension ("extensor lag").
- Finger drop.
- Typical finger deformity.
Pathology
Mallet finger or baseball finger is the rupture of the extensor tendon of the finger at the distal interphalangeal (DIP) joint. The rupture of the finger extensor tendon may sometimes occur in combination with fracture of the distal phalange. The patient is not able to completely straighten the finger.
X-ray
X-ray is used to evaluate if there is an avulsion fracture of the distal phalanx.
In case of an uncomplicated mallet finger injury, splinting of the distal interphalangeal joint (DIP) is done in hyperextension for 8 weeks. Whereas severe mallet finger injuries sometimes require surgical treatment and the splint is worn for additional 6-8 weeks at night or while engaging with sports activities. The splint may be made of plastic or metal, applied to either the dorsal or volar part of the finger. The joint must be kept in hyperextension all the time during the 8 weeks, even when the splint is removed for cleaning.
Medication: Non-steroid, non-inflammatory ibuprofen, naproxen, or acetaminophen.
NOTE: Medication should be taken under the doctor's prescription.
Immobilization
The splint is applied to keep the finger in a straight static position and worn continuously for 6 to 8 weeks. The end joint should not bend during the splint age period. The middle finger joint is kept below the splint to support below the joint being exercised by bending the middle joint of the finger and then straightening it. To wash the finger, lay the hand palm down on a flat surface and slip the splint off to remove it, hold the finger straight on a flat surface without bending. Wash the finger with the hand flat on the table, then slide the splint back on.
Physiotherapy after operative treatment focuses mainly on keeping the other joints mobile and thus preventing stiffness.
Cryotherapy can be useful to relieve pain in the early stages, it can be used 10 -15 minutes 2 to 3 times a day.
Ultrasound can be used to hasten the recovery process.
Joint mobilization
The proximal joints are mobilized to gradually decrease the stiffness and increase the movement in the tip of the finger and after removing the splint the active and passive range of movements are started.
Passive range of motion
Passively bend the injured joint gently to maintain the joint range of motion then straighten back the joint. Each position is held for 5 secs with 10 repetitions 3 to 4 times a day.
Passive finger flexion
Using the other hand to stretch the stiff finger at the tip and middle joints, roll it into a full fist. Repeat for all fingers individually. This exercise can also be done by stretching all 4 fingers at the same time. Hold this position for 5 secs and repeat 10 times.
Stretching exercises
Palms flat on the able hold the finger one at a time and lift each finger at a time, hold this position for 5 secs and repeat 10 times.
Active finger flexor tendon glides
Begin with the wrist and fingers straight. Bend at the first knuckles then touch the fingertips to the base of the palm, making a flat fist. Bring the fingers back into a claw position, maintaining the tension in the fingers, roll them into a full, tight fist. Hold this position for 5 secs and repeat 10 times.
Object pick-up
Practice picking up small objects like pins, buttons, coins, etc.
Grip strengthening exercises
Strengthening exercises can also be useful to restore normal hand and finger strength.
Strengthening exercises like holding a squeeze ball, rubber ball or a therapeutic putty can be very helpful to regain mobility and strength. Hold this position for 5 secs and repeat 10 times.
The splint is worn for up to 4 weeks at night, during this phase do not try to examine how much of the finger has healed by bending it, as it might cause further damage. The patient is educated, how to modify activities to avoid recurrent finger injury.
