A

Tinels sign (1 cm medial and inferior to asis)

44
Q

Pt (intense athlete) comes in with paresthesia + numbness over anterolateral aspect of left thigh w/ no other radiation after using a utility belt for quite some time. they also have gained some weight over last few weeks.

anterior tarsal tunnel syndrome

59
Q

Ant. tarsal tunnel syndrome is compression @which retinaculum?

A

inferior extensor retinaculum

60
Q

Cervical Nerve root compression

A

usually secondary to cervical disc dz

bulging disc–> herniated disc = either protrusion: no leakage of central material or extrusion (worse): nucleus pulposus able to flow out of disc space

61
Q

The cervical nerve root compression causes disc rupture in what direction?

A

posterior-lateral (causes compression of nerve root as exits intervertebral foramen)

Causes RADCULOPATHY

62
Q

You can perform cervial nerve root testing by doing:

A

Compression test or Spurlings maneuver (rotate toward and extend neck)

Adsons (elevate chin and rotate head toward affected side while inspiring deeply)

Hoffmans sign (firmly grasp middle finger and quickly snap/flip dorsal surface looking for flexion of both thumb and index finger)

63
Q

Lumbar spine and cervical spine disc rupture is differnet why?

A

C8 an above pedicle/nere root mismatch; has extra c8 nerve root without pedicle that allows Thoracic ones to match

T1 and below pedicle/nerve root match

Lumbar spine pedicle/nerve root match

64
Q

Compression of superficial radial nerve is called:

A

cheiralgai paresthetica, Wartenbergs syndrome, “handcuff neuropathy”

burning, pain in SRN distribution (2.5 fingers from thumb); caused by compression, edema, and surgical injury

65
Q

Does anterior interosseuous syndrome have symptoms?

A

no sensory symptoms; weak flexion ability tho (median n.)`

66
Q

+ OK sign = what syndrome

A

Median nerve entrapment

67
Q

+Froments sign = what syndrome

A

ulnar nerve entrapment

68
Q

+ hoffmans sign = what sydnrome

A

CNS problem

69
Q

Sciatica:

A

SYMPTOM not a cause; low back pain

70
Q

Post-cast pressure pt case:

A

Ant. interosseous syndrome (median n.)

71
