Procedural clinician


Aluminium finger splint

Trauma shears


Positioning (injury-dependent)

Distal phalanx fracture: DIP extended, splint from tip of finger to PIP (leaving PIP free)

Middle phalanx fracture: IPs extended, splint from tip of finger to MCP (leave MCP free)

Volar plate injury: PIP slightly flexed, extended DIP, splint from tip of finger to MCP (leaving MCP free)

Post relocation of PIP: PIP slightly flexed, extended DIP, splint from tip of finger to MCP (leaving MCP free)

Mallet injury: finger extended, splint from tip of finger to PIP dorsally (leaving PIP free)


Cut aluminium splint to correct length

Tape over sharp splint edges or bevel smooth with trauma scissors

Bend splint at level of PIP to create flexion if required

Apply dorsally over digit

Secure with tape

Post-procedure care

Check X-ray, circulation and limb function:

Confirm fracture or dislocation reduction with post-procedure X-ray

Check capillary refill and comfort (loosen tape or re-splint if required)

Check planned position maintained

Check MCP free to move (and PIP for distal phalanx or mallet injuries)

Provide care instructions:

Elevate finger when possible using high arm sling for three days (decreases swelling and pain)

Advise to remove sling regularly and move non-immobilised joints (to prevent stiffness)

Return for assessment if increasing pain, numbness or skin colour changes


Avoid the common pitfalls of bandaging too tight or impairing function with splints that are too long

Dorsal splints should preserve tactile sense and function while providing immobilisation

Always round the edges for patient safety (use trauma shears to bevel/blunt sharp edges)
