Dyna Finger Extension Splint: Holds a Drooping Fingertip Straight So the Tendon Can Knit
This Dyna finger extension splint holds a drooping fingertip out straight, so a torn tendon on the back of the finger knits back to the bone and the tip straightens again on its own. It is the standard treatment for a mallet finger — the injury where a ball, a bedsheet or a knock bends the end joint and afterwards the tip hangs down and refuses to lift.
It is made by Dynamic Techno Medical, it costs 380 shillings, and it is the least expensive product on this shelf by a wide margin. That price is misleading about how much it matters: worn properly for six to eight weeks, it fixes an injury that otherwise leaves a permanently bent fingertip, and the difference between those two outcomes is entirely in how it is worn. Our pharmacist sizes it and shows you the one thing you have to get right.
The One Rule, and It Is Not Negotiable
The fingertip must stay straight the entire time — including while you change the splint. Every time the tip is allowed to droop, the healing tendon stretches again and the clock goes back to the beginning. People lose a whole recovery by taking the splint off over a basin and letting the finger relax for two seconds.
Six to eight weeks continuously, then two more weeks at night. Continuously means day and night, including sleeping and washing.
To change it, rest the hand palm-down flat on a table. Slide the splint off along the table so the surface holds the tip straight, clean and dry the finger with the hand still flat, and slide the new or cleaned splint straight back on. Never lift the finger off the table while it is bare.
If the tip does droop at any point, tell our doctor. The usual answer is to start the full-time period again, and starting again is far better than stopping early.
If the splint comes off early, the finger is unlikely to straighten by itself later. That is why our pharmacist spends time on this at the counter rather than just handing over a 380-shilling splint.
What It Is For
Mallet finger, where the end joint will bend but refuses to straighten on its own after a knock.
Extensor tendon injuries on the back of the finger, where the tendon has been cut or torn.
Boutonnière deformity, where the middle joint bends and the tip tilts back, on our doctor’s instruction.
Holding a finger straight after an operation, where the surgeon has asked for it.
And protecting a healing finger through work and sleep once the main splinting period is done.
Fitting It
The splint has to hold the tip just straight, or very slightly lifted. A splint that lets the tip sag even a little is doing nothing; one that bends the tip backwards hard will blanch the skin and cause a sore.
Size it to the finger, not to the hand. Tell our pharmacist the length from the last knuckle to the fingertip and the width across the tip, and bring the finger in if you can.
The middle joint stays free. Only the end joint is held, so you can still bend the finger at the knuckles and use the hand.
The tape or strap should be snug and flat, with no ridge pressing across the nail bed.
Look at the skin every single day. Whiteness over the back of the end joint, a red mark that stays red when you press it, broken skin or a nail that is going dusky all mean the fit needs changing today. Please come in and we will adjust it.
Living With It for Two Months
Keep the finger dry. Wash with the hand in a bag or a glove, dry thoroughly around the splint, and clean under it using the table method above.
Expect the finger to look odd afterwards. The end joint is usually stiff for a while and a slight bend may remain even with perfect splinting. That is a normal result rather than a failure.
Start moving it only when our doctor says. Coming out of the splint is done in stages, because a tendon that has just knitted stretches easily.
Keep the other joints moving the whole time. Bend and straighten the knuckles and the middle joint daily to keep the finger supple while the tip is held.
Where the whole hand needs holding open rather than one fingertip, the cock up splint with finger extension is the device our doctor asks for, and for the wrist alone the cock up splint is the one.
Is a Finger Extension Splint Right for You?
This splint suits a mallet finger, extensor tendon injuries and a finger held straight after an operation. Please speak to our doctor before buying one if any of these apply:
- Nobody has examined the finger. A mallet finger sometimes takes a flake of bone with it, which changes the treatment, so please come to our doctor or go to a hospital first rather than splinting it blind.
- The skin over the finger is cut, broken or dirty, or the injury came from a bite or a dirty object. That needs seeing today.
- The finger is crooked sideways, or you cannot bend it at all.
- The fingertip is cold, pale, dusky or numb. Go to a hospital today.
- You have diabetes, poor circulation or reduced sensation in the hands, since a splint worn for eight weeks needs checking by somebody else daily.
Our pharmacists will size the splint, show you the table method for changing it without letting the tip droop, and tell you what to look for on the skin, and our doctor will examine the finger and say how long it stays on.

FAQs
My fingertip bends but will not straighten after a knock. What is that?
That is the classic description of a mallet finger: the tendon that straightens the end joint has torn away from the bone, so the tip hangs down and cannot lift on its own. It is what this splint is for. Please let our doctor examine it first, because it sometimes takes a flake of bone with it and that changes the treatment.
How long do I have to wear it?
Six to eight weeks continuously, then a further two weeks at night. Continuously means day and night, including sleeping and washing. Our doctor will confirm the length for your finger.
Can I take it off to wash?
Yes, but only using the table method, and never by simply pulling it off. Rest the hand palm-down flat on a table, slide the splint off along the table so the surface holds the tip straight, clean and dry the finger with the hand still flat, then slide it straight back on. Never lift the bare finger off the table.
What happens if the fingertip bends while the splint is off?
The healing tendon stretches again and the clock goes back to the beginning. Tell our doctor; the usual answer is to restart the full-time period, and restarting is far better than stopping early.
Can I stop early if it looks straight?
Please do not. If the splint comes off before the time is up, the finger is unlikely to straighten by itself later. The tendon looks healed long before it is strong.
What size do I need?
Tell our pharmacist the length from the last knuckle to the fingertip and the width across the tip, and bring the finger in if you can. It is sized to the finger rather than to the hand.
Should the tip be straight or bent backwards?
Just straight, or very slightly lifted. A splint that lets the tip sag even a little is doing nothing. One that forces the tip back hard will blanch the skin and cause a sore, so bring it in and we will adjust it.
Will I still be able to use my hand?
Mostly. Only the end joint is held, so the knuckles and middle joint still bend and you can grip, write and work. Keep those joints moving daily so the finger does not stiffen while the tip is held.
What should I look for on the skin?
Check it every day. Whiteness over the back of the end joint, a red mark that stays red when you press it, broken skin, or a nail going dusky all mean the fit needs changing that day. Please come in and we will adjust it.
Will my finger be completely normal afterwards?
Usually it recovers well, and a slight bend may remain even with perfect splinting. The end joint is also stiff for a while once the splint comes off. Both are normal results rather than a failure.
When can I start bending it again?
Only when our doctor says, and in stages. A tendon that has just knitted stretches easily, which is why coming out of the splint is done gradually rather than all at once.
Can I use it for a broken finger?
Please let our doctor examine it first. Finger fractures are splinted in different positions depending on which bone and where, and the wrong position held for weeks causes its own problem.
Can I wear it to work?
Yes, and you will need to, since it stays on continuously. Keep it dry, and if your work is wet or dirty ask our pharmacist about covering it.
