Upper Extremity Flashcards
What nerve is affected with ape hand deformity?
Median
What nerve is affected with wrist drop?
Radial
What is normal position for the wrist and arm in a WHO?
15-30* dorsiflexion, no ulnar or radial deviation, neutral pronation - supination
What residual function would you expect with a complete C-6 Cervical lesion?
Wrist Extension
What is your orthotic recommendation for above?
wrist driven flexor hinge splint
How does a wrist driven function?
tenodesis action from wrist extension to cause grasp
Name 6 prehension patterns.
Spherical Tip Palmer Cylindrical Hook Lateral
A thumb post should hold the thumb in what position?
in opposition to index and 2nd finger
What type of orthosis would you use for an intrinsic minus hand? RX rational?
HO
What type of orthotic devices would you use for a patient with a complete C-5 lesion?
static WHO, mobile arm supports
What is clonus?
A rapid alternating involuntary movement elicited by stretch
How many cervical neural segments are there?
8
True/False: At the neural segmental level of the spinal cord lesion there will always be a return reflex action.
False
Describe a rotator cuff injury
Damage to the SITS muscles in the shoulder
What is your orthotic recommendation for rotator cuff
Immobilize shoulder in slight abduction - airplane splint
Describe Erb’s palsy and make orthotic recommendations
Avulsion of C5-6 roots resulting in a flail arm (finger flexors & extensors intact)
“gunslinger” orthosis to position hand and support shoulder
What type of neural injury normally results in flaccid paralysis (upper motor, CNS, peripheral)
Peripheral nervous system injuries
What muscles flexes, abducts, extends and supports the shoulder joint?
Deltoid
What should 1 of your primary concerns be in upper extremity orthotics for spinal injury?
Insensate skin sensitive to pressure
What orthosis would you recommend for a hand with lumbricales, interossei & thumb abduction out? Why?
HO with C-bar & MP extension stop to maintain thumb web space, flex MPs allowing long extensors to extend IPs DIPS
Describe the etiology of carpal tunnel syndrome
compression of the medial nerve in the carpal canal caused by edema, synovitis, & fibrosis of the tendon sheath
how long would you treat a mid-humeral fracture with radial nerve lesion?
humeral fracture brace with positional cock up splint and sling
How do you position for carpal tunnel syndrome?
immobilize in neutral
radial nerve injury
lose extensors of wrist and elbow, supinator & thumb abduction
