Wrist
Digits
Thumb
Index finger
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
