A fingertip protector is a small rigid shell over the end of the finger that shields a healing tip from knocks while leaving the rest of the finger free to move.
It’s used for crushed fingertips, tuft fractures of the tip bone, nail bed repairs, fingertip amputations and flaps, and fingertips that have become too sensitive to touch.
It lets you use the hand while the tip heals, instead of guarding it all day.
What it does
- Takes the knocks. A healing fingertip gets bumped dozens of times a day, and every bump hurts and delays healing
- Supports a tuft fracture, the break in the tip of the end bone, which usually heals without surgery
- Protects a nail bed repair while the new nail starts to grow
- Keeps the dressing in place and off surfaces
- Leaves the middle and knuckle joints free, and often the end joint too, so the finger doesn’t stiffen
A protected fingertip gets used. An unprotected one gets held out of the way, and then the whole finger stiffens.
What it’s used for
- Crushed fingertips and tuft fractures from doors, hammers and machinery
- Nail bed repairs after a nail has been lifted or torn
- Fingertip amputations healing on their own or after a flap
- Hypersensitive fingertips after injury, alongside a desensitization program
A fingertip injury with a drooping end joint is a different problem. See mallet finger.
The designs
- Thermoplastic cap: molded over the tip, often with a gap for the dressing
- Padded aluminum: quick, adjustable, common in emergency departments
- Silicone thimble: for later stages and sensitive tips
A typical timeline
- Weeks 0 to 2: worn most of the time, off for dressing changes. Bend and straighten the finger several times a day
- Weeks 2 to 4: worn for activity and anywhere the tip might be knocked
- Weeks 4 to 6: weaned. Tapping, textures and pressure on the tip to reduce sensitivity
- Months 3 to 6: a torn nail takes this long to regrow, and the tip may stay sensitive in the cold for months
Problems to watch for
- Soft, white skin from sweat or a wet dressing under the cap
- Stiffness at the end joint if the cap includes it for longer than needed
- Over-protecting. A tip that never gets touched stays sensitive for longer
Get it checked if
- Throbbing pain, spreading redness, pus or fever. See infected fingertip
- A dark or cold tip
- Sensitivity getting worse instead of better after 6 weeks
This is one of dozens of splints a hand therapist makes. See what a hand therapist does for the full list.
Protect the tip so the hand keeps working, then wean it so the tip toughens up.
