Thumb

Little Finger
Long
Short
Flexor Digitorum Profundus VS Flexor Digitorum Superficialis
FDP passes through (DIP)
FDS splits and stops (PIP)
Intrinsic VS Extrinsic
Intrinsic = muscles that are apart of the hand
Extrinsic = muscles that are in the forearm with tendons leading into the hand
Flexor Carpi Radialis
Flex wrist, radial deviation
Flexor Carpi Ulnaris
Flex wrist, ulnar deviation
Flexor Digitorum Superficialis
Flex fingers up to PIP
Flexor Digitorum Profundus
Flex fingers to DIP
Extensor Carpi Radialis Longus
Extend wrist, radial deviation
Extensor Carpi Radialis Brevis
Extend Wrist, radial deviation
Extensor Digitorum
Extend fingers
Extensor Digiti Minimi
Extend little finger
Extensor Carpi Ulnaris
Extend wrist, ulnar deviation
Extensor Indices
Extend index finger
Lumbricals
IP extension, MP flexion
Interossei
finger abduction/adduction
Glenohumeral Rhythm
during adduction, humerus does the movement until 90 degrees, then the scapula rotates past 90 degrees
Collateral Ligaments
Common cause of IP flex contractures post surgery or edema/trauma.
Natural Tension (tendons)
many muscle spread over multiple jts and stretch; position affects ROM, strength, impt for tendon repair and useful for tenodesis
Functional Position of the Hand
Slight extension of the wrist
zero position = resting position
DR CUMA
Drop Wrist = Radial Nerve
Claw Hand = Ulnar Nerve
Ape Hand = Median Nerve
Purpose of Orthoses
Immobilize early to protect, mobilize later to correct
The 5 P’s of Splints (purpose)
Pain = Arthritis
Paresthesia = Nerve compression, CTS
Protection = fx or s/p surgery
Positioning = Weakness, drop wrist
Prevention = Contractures
Stages of Healing
Inflammation = avoid infection (a few days)
Proliferation = forming scar tissue (2-8 weeks)
Maturation = remodeling (months to a year)
Splints purpose during the 3 stages of healing
inflammation = stabilize
proliferation = stabilize and cautiously grading movement/activity
maturation = getting back to typical fx
Static Splint
generic splint, immobilizes and protects
- constant pressure
- immobilize, protect, position (prevent but functional
i.e., wrist cock up
Serial Static Splint (serial casting)
series of static splints, or splint that is reheated and adjusted to the clients new available ROM to improve it
-constant pressure
-adjusted over time
-purpose = mobilize and improve PROM
Static Progressive Splint
Static, adjustable, non-elastic, 90 degrees, purpose = mobilization, improve PROM, good on stiff jts, follow wear with active use.
Dynamic splint
dynamic, elastc, 90 degrees, purpose = mobilization, improve PROM, resistance exercise, assist with movement (i.e., readial nerve palsy)
Purpose of mobilization splints
Remodel scar tissue
contractures
increase ROM
movement
resistance exercise
jt fx reduce
Resting hand splint
general comfort
slight wrist extension
common after stroke
Anti-deformity Splint (intrinsic Plus)
Alligator Splint
Slight wrist extension
MCP flex
IP, DIP, PIP in extension
for trauma or edema
Long/Short Thumb Spica
Unicorn splint
Long spica = de quervain
short spica = arthritis of CMC/MP of thumb
Thumb is slightly flexed and abducted, wrist slightly extended
unrestricted movment of digits 2-4
Dorsal Block Splint
Back side of hand
flexor tendon repair to limit flexion to decrease risk of rupture
slight wrist flex (20 degrees), MP at 50 degrees
Wrist Cock Up splint
Radial nerve
Radial nerve palsy
Radial tunnel syndrome
carpal tunnel syndrome
Posterior Elbow Splint
MCL/LCL injury, elbow recovery at 90 degrees
Anterior Elbow splint
can be used for burn or to promote extension
Mallet Splint
injury to extensor tendon of DIP
MUST USE SPLINT for 6-8 weeks or you have to start all over. Finger must stay in extension when client changes splint
Boutonniere Splint
Oval 8
arthritis
