CMC/MP Immobilization Orthosis (Short Opponents) - position to allow thumb to index
opposition
Purpose: heal and protect then prevent re-injury
Schedule: initially 24/7, then prn for aggravating activity
78-year-old: Dupire’s Little Digit (s/p surgical release 2 days ago) - CORRECT
ANSWER Orthosis: 5th Ray (or MP/PIP/DIP) Flexion Restriction Splint - max extension,
adjacent digit if little/ring; dorsal allows air to surgery site
Purpose: extension position to prevent scar formation to cause flexion contracture
Schedule: 24/7; remove for therapy, wound care
75-year-old: Trigger Finger (RF) - A1 Pulley-Flexor Tenosynovitis (developed over time,
retired, crochets daily) - CORRECT ANSWER Orthosis: 4th MP Flexion Restriction
Splint - MP 0degrees
Purpose: reduce inflammation; rest tendon at A1 pulley
Schedule: 24/7 for 2-3 weeks
62-year-old clerk: Carpal Tunnel Syndrome (completes data entry with intermittent
tingling/pain; wakes with tingling at 2am) - CORRECT ANSWER Orthosis: Wrist
Immobilization Splint - prefab or custom fabricated - 0-10 extension
Purpose: allow the most space in carpal tunnel to reduce pressure to median nerve
Schedule: HS; optional during aggravating activity
36-year-old: Flexor Tendon Laceration (3 days ago - FDS, FDP of ring and little cut
palm on tuna fish can lid, surgical repair today) - CORRECT ANSWER Orthosis:
,wrist/digits 2-5 Extension Restriction Splint - wrist 20 flexion; MP 50 flexion; PIP&DIP
slight flexion
Purpose: prevent disruption of flexor tendon (passive protocol: add rubber bands -
passive flexion and active extension; active or immobilization protocol: no bands)
Schedule: 24/7
45 years old: radial neuropathy (Saturday night Palsy) - excessive intoxication; slept
heavily with arm in full flexion - CORRECT ANSWER Day Orthosis: Wrist/2-5th MP
Extension Mobilization Splint - can include thumb with outrigger
Purpose: allow tenodesis function
Schedule: continuous, remove for ROM exercise, hygiene
Night Orthosis: Wrist Extension Immobilization Splint
Purpose: prevent over stretch of extensor tendons
Schedule: HS
37-year-old: s/p repair of lacerated ulnar nerve at wrist (knife injury while washing
dishes) - CORRECT ANSWER Orthosis: 4&5 MCP Extension Restriction Splint - MP at
60
Purpose: transfer power of intrinsic to IP joints; prevent over stretch of intrinsic
Schedule: continuous; remove for exercise and hygiene
67-year-old: CVA with spastic hemiparesis of LUE
(increased flexor tone - especially at wrist and hand resulting in fisting hand - skin
breakdown where nails are; able to perform PROM to near neutral position) -
CORRECT ANSWER 1. Orthosis: Wrist hand immobilization splint with hand cone
(cone splint)
Purpose: provides deep pressure to flexion tendons in hand to inhibit flexor tone
Schedule: HS or during ambulation; dependent on severity
OR
2. Orthosis: wrist hand immobilization splint - with thumb/digit abduction (Finger
spreading Splint)
Purpose: reduces flexor tone due to reflex inhibiting pattern
Schedule: HS; can use during ambulation if severe
3-year-old: thumb web space contracture from well healed burn - CORRECT ANSWER
Orthosis: wrist hand immobilization splint - thumb in radial abduction; greater MP
extension
Purpose: open hand position to prevent scar from pulling hand into fisted position
Schedule: initially all the time; once healed enough to use hand: HS
, 8-year-old with burns covering left chest and axilla following fire pit accident -
CORRECT ANSWER Orthosis: shoulder abduction immobilization splint (airplane or
axillary splint)
Purpose: position at end range to prevent scar from creating contracture in adduction
position
Schedule: 24/7 transition to HS as heals
26-year-old: burn to hand following house fire - CORRECT ANSWER Orthosis: wrist
hand immobilization splint - increase MP flexion to 60 degrees; thumb in radial
abduction
Purpose: MP flexion protects intrinsic from shortening; radial thumb prevents web space
contracture
Schedule: begin 24/7 transition to HS as heals to provide opportunities for functional
use
Splint - CORRECT ANSWER an orthopedic device for immobilization, restraint, or
support of any body part
orthosis - CORRECT ANSWER a force system designed to control, correct, or
compensate for a bone deformity, deforming forces, or forces absent from the body
custom fabricated splints & advantages - CORRECT ANSWER made from low
temperature plastics (thermoplastic)
advantages: form fitting, sports, bathing
immobilization splint: purposes - CORRECT ANSWER rest and protect - reduce pain
and inflammation; safe position to engage in occupations; fractures, arthritis, external
fixators)
prevent further deformity - maintain tissue length balance and excursion; prevent
further/correct tone
prevent soft tissue contracture - as soft or scar tissue is growing (to guide growth in a
functional manner); burn victim
restriction splint: purposes - CORRECT ANSWER prevent/correct deformity - swan
neck deformity; rheumatoid arthritis; protect from tear of stitches while the body heals
prevent soft tissue contracture -
Mobilization Splint: purposes - CORRECT ANSWER aka dynamic splint
Control Movement - buddy taping - realign and/or maintain joint alignment (springs
control movement)
