Key facts

Splinting at a glance.

The essentials, in plain English. What splinting is, who provides it and the categories every UK hand therapist works with.

  • What it is

    Orthotic therapy for the hand and wrist. A splint (or orthosis) rests, protects, positions or moves a joint to help it heal or function.

  • Who fits them

    Specialist hand therapists, usually BAHT-accredited physiotherapists or occupational therapists working alongside hand surgeons.

  • Static vs dynamic

    Static splints rest and protect. Dynamic splints apply controlled force through elastics, springs or pulleys to move or guide a joint.

  • Custom vs off-the-shelf

    Custom thermoplastic splints are moulded to the hand for precise fit. Off-the-shelf neoprene or fabric splints suit milder or short-term needs.

  • Common uses

    Carpal tunnel, de Quervain, trigger finger, CMC osteoarthritis, mallet finger, tendon repair, fractures and rheumatoid disease.

  • Adherence is everything

    A splint only works when it fits well, is worn as prescribed and reviewed regularly. Comfort and pattern of wear are the two levers.

Why this guide matters

A working tool, not a finished product.

Splints look simple. Choosing, fitting and progressing them is not. The three points below shape everything else on this page.

  • The splint has to match the problem

    Rest, protection, blocking, controlled motion and progressive stretching each call for a different splint type and material.

  • Fit and adherence beat everything

    A perfect splint left in a drawer does nothing. A slightly imperfect splint worn to schedule delivers most of the benefit.

  • Review changes the outcome

    Splints are adjusted as swelling settles, range improves and healing progresses. Regular review with a hand therapist is the real intervention.

How the splint is chosen and fitted

From first assessment to a splint that fits.

The steps a UK hand therapist normally follows, in order, so you know what to expect and why fit is checked more than once.

  1. 01

    Assessing

    Hand therapy assessment

    Full history, examination and functional review by a specialist hand therapist to define the goal of splinting.

  2. 02

    Assessing

    Match splint to problem

    The diagnosis and stage of healing decide the splint type: rest, protect, block motion, correct contracture or guide tendon glide.

  3. 03

    Assessing

    Custom or off-the-shelf

    Custom thermoplastic is chosen when fit matters most. Neoprene or prefabricated splints suit milder cases and short-term use.

  4. 04

    Fitting

    Moulding and fitting

    Thermoplastic sheet is heated, moulded directly on the hand, trimmed and lined. Pressure points are checked before you leave.

  5. 05

    Fitting

    Wearing schedule

    A clear plan for when to wear the splint, when to remove it and which exercises to do out of the splint.

  6. 06

    Progressing

    Review and adjust

    Splints are reviewed at one to two weeks and again as swelling settles or range of motion changes. Small tweaks make a big difference.

  7. 07

    Progressing

    Wean and progress

    As healing progresses the splint is worn for shorter periods, then only at night, then only for specific tasks.

Typical timeline: from first assessment to a settled splint programme in a handful of visits.

Splint types

The main splint families.

Static, dynamic, serial static and static progressive. The right family depends on whether the goal is rest, motion or gaining range.

  • Static splint

    Rigid rest and protection. Immobilises a joint in a chosen position for healing, symptom relief or night use.

  • Dynamic splint

    Applies controlled force through elastics, springs or pulleys. Guides motion after tendon repair or joint stiffness.

  • Serial static and serial casting

    Progressive stretching for a stiff or contracted joint. The splint is remoulded each visit to gain a few more degrees.

  • Static progressive and turnbuckle

    Adjustable static end range with a screw or dial. Holds a stretch at tolerance without constant pull.

  • Wrist neutral splint

    A resting wrist splint at neutral. First-line for carpal tunnel syndrome, particularly overnight.

  • Thumb spica

    Immobilises the thumb and wrist for de Quervain tenosynovitis, scaphoid injuries and thumb CMC flares.

  • Stack and PIP splints

    Small finger splints for mallet finger (DIP extension) and boutonniere or swan neck deformity at the PIP joint.

  • Red flag - pressure or numbness

    Persistent pain, skin marking, tingling or colour change under a splint means it needs adjusting, not tolerating.

Common uses

What splints are used for.

A shortlist of the conditions where splinting changes outcomes, from carpal tunnel and de Quervain tenosynovitis to hand fractures and tendon repair.

  • Wrist neutral splint (carpal tunnel)

    Nocturnal wrist splint in neutral is first-line evidence-based care for mild to moderate carpal tunnel syndrome.

  • Thumb spica (de Quervain)

    Forearm-based thumb spica rests the first extensor compartment. Worn full-time initially, then weaned.

  • MP blocking splint (trigger finger)

    A small splint that holds the MP joint straight, encouraging tendon glide at the pulley. Effective in early trigger finger.

  • CMC opponens (thumb OA)

    Short opponens splint in neoprene (Comfort Cool, Push MetaGrip) or custom thermoplastic offloads the thumb base for arthritis.

  • Stack splint (mallet finger)

    DIP joint held in full extension for six to eight weeks continuously, then a further weaning phase at night and in sport.

  • PIP splints (boutonniere and swan neck)

    PIP extension splint for boutonniere; Silver Ring or PIP hyperextension block for swan neck deformity.

  • Post-fracture and post-surgical

    Protective static splints after hand fractures, tendon repair or joint surgery. Fit is remoulded as swelling settles.

  • Dynamic tendon protocols

    Kleinert (dynamic passive flexion) and Duran (early passive motion) programmes after flexor tendon repair, always specialist-led.

Also frequently splinted

Hand and wrist osteoarthritis, trigger finger, rheumatoid and psoriatic arthritis of the hand, burns and oedema (Coban wrap and pressure gloves), sport injuries (custom playing splints and taping) and specialist neurological hands after stroke or with spasticity. Splinting for CRPS, scaphoid fractures and Volkmann contracture is specialist-only.

Red flags

When a splint needs urgent review.

Most fit issues are minor and quickly solved. These are the situations that are not, and where a specialist opinion is needed.

  • Pressure sores or skin breakdown

    Redness that does not settle within 20 minutes of removing the splint, blistering or broken skin means the splint needs adjusting urgently.

  • New or worsening numbness

    Tingling or numbness under or beyond the splint suggests nerve compression from strap placement or trim lines. Loosen and review same week.

  • Cold, pale or dusky fingers

    Any change in colour, temperature or capillary refill is a circulation warning. Remove the splint and contact your hand therapist.

  • Increasing pain in the splint

    Pain that rises rather than settles in the first week is not normal. It usually reflects fit, position or an underlying problem needing review.

  • Loss of range after tendon repair

    Loss of active flexion or extension during a Kleinert or Duran protocol is a specialist emergency, not something to wait out.

  • Fever, spreading redness or discharge

    Signs of infection under a splint after surgery need urgent medical review, not a splint adjustment.

  • Suspected scaphoid or occult fracture

    Persistent snuffbox pain after a wrist injury needs imaging and specialist splinting, not an off-the-shelf brace from a pharmacy.

  • CRPS features

    Disproportionate burning pain, colour change, swelling and hypersensitivity after an injury or surgery need urgent multidisciplinary care.

  • Neurological hand (stroke, spasticity)

    Splinting for stroke, cerebral palsy or spasticity is specialist-only. A poorly chosen splint can worsen tone or cause pressure injury.

Living with it

A practical tool, worn with a plan.

Four things that make the biggest difference day to day. Comfort, adherence to the wearing schedule, the exercises out of the splint and regular review.

A quiet reminder

Comfort is data, not weakness.

If your splint hurts, tell your hand therapist. Trim lines and straps are meant to be adjusted, and small tweaks unlock big gains.

  1. 01 Fit

    Comfort tells the truth

    A well-fitted splint should be firm, not painful. Red marks that fade in 20 minutes are fine. Anything longer needs adjusting.

  2. 02 Routine

    Wear as prescribed

    Night-only, full-time or task-specific matters as much as the splint itself. Follow the schedule your hand therapist writes down.

  3. 03 Exercises

    Move what you are told to move

    Most splint plans include exercises out of the splint. Skipping them causes stiffness that outlasts the original problem.

  4. 04 Review

    Bring it to every appointment

    Small adjustments to trim lines, straps and angle unlock big gains. Your splint is a working tool, not a finished product.

Frequently asked

Everything we get asked about hand and wrist splinting.

Quick answers on static and dynamic splints, custom versus off-the-shelf, wearing schedules and what to do when a splint hurts.

  • What is hand and wrist splinting?

    Splinting (also called orthotic therapy) is the use of a custom or off-the-shelf device to rest, protect, position or guide the hand and wrist. It is provided by specialist hand therapists, usually BAHT-accredited physiotherapists or occupational therapists working with hand surgeons.

  • What is the difference between a static and a dynamic splint?

    Static splints hold a joint still to rest and protect it. Dynamic splints use elastics, springs or pulleys to apply a controlled force that moves or guides a joint, typically after tendon repair or for stiff joints. Serial static and static progressive splints sit between the two and are used for contractures.

  • Do I need a custom thermoplastic splint or will an off-the-shelf one do?

    It depends on the problem. Custom thermoplastic splints are moulded to your hand for a precise fit and are used after surgery, for complex conditions or when exact position matters. Off-the-shelf neoprene or fabric splints are appropriate for milder problems such as thumb CMC osteoarthritis or short-term wrist support.

  • How long should I wear my splint each day?

    That depends on the condition. A nocturnal wrist splint for carpal tunnel is worn overnight. A thumb spica for de Quervain is worn most of the day and night at first. A stack splint for mallet finger is worn continuously for six to eight weeks. Your hand therapist will write your schedule down.

  • Does splinting really help carpal tunnel syndrome?

    Yes. Nocturnal wrist splinting in neutral is a well-evidenced first-line treatment for mild to moderate carpal tunnel syndrome. It reduces night waking and symptoms in most people and is often combined with activity change and, where indicated, a steroid injection.

  • What should I do if my splint hurts or leaves marks?

    Some redness that fades within 20 minutes is expected. Persistent redness, blistering, pain, numbness or colour change is not. Loosen the straps, contact your hand therapist and ask for a review. Splints are meant to be adjusted; small tweaks usually solve the problem.
