Terms in this set (43)
Signs and symptoms of a BP injury
Numbness; tingling; pain; reduced or absent sensation, motor function or reflex, reduced or heightened sympathetic response; abnormal posturing of extremities
"Stinger" aka compression to plexus
Can't feel fingers/arm
Axillary nerve is compromised
Deltoid is out
Military patch sign
"Stinger" diminished sensation
Brain and SC
Which central nerve doesn't originate on the brain?
Innervate skeletal muscle and transmit sensation
Smooth muscles in heart and glands
Dermatomes are part of the?
PNS and somatic
Anterior Rami supplies nerve fibers to?
The muscle, joints and skin of the front of the body
Posterior Rami supplies nerve fibers to?
Muscles, joints and skin of back of body
Avulsion/lesion at C8 band T1
What are the three indications of horners syndrome?
Ptosis = dropping of eyelid
Mitosis = constriction of pupil
Anhydrosis = dry eye/lack of sweat
Thoracic outlet syndrome
Anything to make outlet more narrow
Usually compression of the nerves
Coracoid process/pec major
First rib/clavicular callous
Arms ABD at 90 w/ ER
Open and close hands
They can't hold this position long because they get tired, bad venous return in hands
ER, ABD, Ext
Have them turn there head with your finger on their radial pulse. look for change in HR
What are the causes of a laceration of a BP injury?
_______ is secondary to inflammation from any infection of axillary region.
How do you track nerve healing?
Observation, sensory evaluation, manual muscle testing, nerve conduction, functional activities
Nerve healing is affected by?
Age, general health, etiology of injury, extent of damage, personal habits [smoking, alcohol, caffeine], fitness, nutrition
What is another name for upper plexus lesion?
Superior trunk = C5 &
Etiology of a upper plexus lesion
Traction, motor cycle, birth injury, football
Superior Trunk = C5 & C6
Occurs when arm is pulled forcefully downward
[goes with ERB]
Deformity = ADD, IR, elbow ext, probated forearm, flex wrist
Sensory losses in digits 1 & 2 and radial forearm
Muscles affected = deltoid, supraspinatus, T minor, infraspinatus, biceps, brachialis, brachioradialis, wrist extensors
Lower Plexus Lesion aka?
Etiology of Lower Plexus Lesion
Traction, birth injury, falling
Inferior trunk = roots c8 & t1
Compression - cervical rib
Arm is pulled forceful upwards
Loss of intrinsic hand functions
Positions of deformity in Klumpke
Flex wrist and IPs
Muscles affected in Klumpke
Forearm flexors, intrinsic hand, forearm extensors
Whole plexus lesion
Loss of all motor function in extremity
Loss of all sensation
How? Auto accident/significant trauma
What are the two variations in the BP that we talked about?
Postfixed = lacks C5 and has T2
Prefixed = has c4 and lacks T1
Arises from rami and trunks:
Nerves = Dorsal scapular , long thoracic, suprascapular, nerve trouble subclavius
Dorsal scapular nerve
Long thoracic nerve
Supraspinatus and infraspinatus
Arise from the divisions, cords, and terminal branches
Nerves: lat and medial pectoral, medial antibrachial and brachial cutaneous, upper and lower subscapular, thoracodorsal nerve
Injury to the long thoracic nerve
Thoracodorsal nerve injury?
Injury to the mid shaft of humerus would injure what nerve?
If neck of humerus was injured, would nerve would be affected?
If the medial epicondyle on the humerus is hurt, what nerve is affected?
Saturday night palsy
Pressure on midshaft humerus = radial nerve compression
So wrist drop, weakness in triceps, posterior surface of hand sensation loss
Posterior cord compression = axillary and radial
Teach them how to not lean on brachial plexus
Compression of musculocutaneous and radial nerve
