OS3 year 2 exam 1 -Hannah Flashcards
systemic causes of compression neuropathy
pregnancy
hypothyroidism
diabetes
three sites of radial nerve entrapment and associated symptoms
- high on the humerus
sx: wrist drop, weak elbow flexion, tricep weakness - radial tunnel
sx: pain and tendernesss 5cm distal to lateral epicondyle , wrist drop , pain with resisted supination - at the wrist
sx: sensation changes over posterolasteral hand
what nerve causes pronator syndrome
sx: achy pain in the mid/proximal forearm, pain with resisted forearm pronation and cramping in the fingers
median N.
-compression by the pronator trees muscle
anterior interosseous syndrome
- anterior interreouses N. from the MEDIAN N.
sx: NO sensory symptoms, cannot make “OK” sign with thumb and index finger properly - weak flexion of the index finger DIP and thumbs IP
sx: parathesia to the 4th and 5th digits, medial elbow pain radiating to the hand with decreased intrinsic muscle strength (can’t turn a key in the door)
* + Tinel sign at elboww
ulnar nerve entrapment in cubital tunnel syndrome
*reproduction with elbow flexion, wrist extension
what is froments sign and when do you see it
patient must flex thumb in order to pinch paper between 1st and 2nd digit
seen in cubital turner syndrome of ulnar n. entrapment
what is the most common compression syndrome
median N entrapment at the CARPAL TUNNER SYNDROME
sx of carpal tunnel syndrome
nighttime numbness of lateral 3 1/2 digits, tingling, wrist pain, dropping things, thenar atrophy
dx gold standard for carpal tunnel syndrome
EMG
sx of thoracic outlet syndrome
weakness, parathesia of medial arm forearms and hand worsened by overhead activity
what causes a positive tinnels sign 1cm medial and inferior to ASIS
meralgia parasthetica (lat fem cutaneous n.)
what compression is caused by “strawberry pickers palsy” (time spent in squatting position), or leg hooked over a rail, or ANKLE SPRAINS
common fibular nerve compression
sx: pain along proximal third of lateral leg, steps make louder sound on affected side (foot drop) , pain worsened with plantar flexion and inversion of the foot
plantar flexion and foot inversion makes the fibular head go _____
posterior
*PIP
tarsal turner syndrome (assoc with autoimmune diseases and diabetes)
compression of the posterior tibial n. in the tarsal tunnel behind the medial malleolus and overlying flexor retinaculum
sx: affects motor to plantar (bottom) muscles of foot and sensation to plantar aspect of the foot and toes
anterior tarsal tunnel syndrome
- compression of deep fibular nerve by the inferior extensor retinaculum
- sx: pain over dorsomedial aspect of foot and worse at rest, weakness of extensor digitorum braves
- caused by prolonged plantar flexion or compression from shoes, or soccer
cervical nerve root compression is caused by
2 degree to cervical disc disease
(herniated or bulging disc)
= radiculopathy
bulging disc vs herniated disc
bulging
-compresses every without tearing to cartilage rings
herniated
-tearing of cartilage rings
(protrusion- few tearing, no leakage)
(extrusion- torn in a small area, nucleus pulposus is able to flow out of disc space)
technique: extending and rotating the neck toward the symptomatic side, look for exacerbation of radicular pain
dx: cervical radiculopathy (herniated disc)
spurling test
technique: elevate patient chin (extend neck) and rotate head toward affected side while inspiring deeply, look for decrease in radial pulse on affected side
dx: thoracic outlet syndrome (plexopathy)
adsons test
technique: firmly grasp the middle finger and quickly snapping or flipping the dorsal surface, look for quick flexion of both the thumb and index finger
dx: cervical myelopathy (c-spine stenosis)
hoffmann tets
compression of the superficial radial N., (cheiralgia parathestica, wartenbergs syndrome, “HANDCUFF NEUROPATHY”)
numbness, pain, tingling in the posterolateral hand and distal forearm
-compression of the radian n. at the wrist between the ECRL, and brachioradialis M.
baseball players and dentist are likely to get what compression neuropathy
median n. entrapment as PRONATOR SYNDROME
what muscle is weak in anterior interrosseous syndrome as seen with with pts with forearm casts
flexion pollicus longus muscle and flexor digitorum M.
three test to dx carpal tunnel syndrome
tinels, phalens, 2 point discrimintion
lumbosacral radiculopathy (sciatica) vs piriformi syndrome sx
sciatica travels down to foot, and low back pain, and caused by herniated disc most often at the left of L5-S1 (affects L5 nerve)
piriformis syndrome - pain stops at or above kneee and radiates from the gluteal region, contralateral sacroiliac pain (SI JOINT PAIN) can have gait problems (foot drop) and weakness in ipsilateral LE
lat fem cutaneous comes from what lumbosacral nerve roots
L2 -L3
and nerve is compressed by inguinal ligament
common fibular N. lumbosacral nerve roots
L4-S2
tx for tarsal turner syndrome (posterior tibial N.)
gastrocnemius counterstain , calcaneal HVLA, talar tug HVLA, ankle figure 8
if there is a thoracic and rib TP, which do you treat first?
thoracic
2 cm lateral to medial end of the clavicle
AC 7
(clavicular head of the SCM)
(F StRa)
medial end of the clavicle
AC 8
(sternal head of SCM at the sternal notch )
(F SaRa)
inferior tip of xiphoid or 1/4 of the way between the xiphoid tip and umbilicus
AT 7
tx: patient sitting- knee on opposite side of TP, FSTRA
3/4 way between xiphoid and umbilicus
AT 9
tx: patient sitting- knee on opposite side of TP, FSTRA
