Cock up splint

10
Q

Sciatica is caused by nerve root compression due to ? and at the level of?

Due to herniation at the L4-L5 or L5- S1

10
Q

T or F: Steppage gait may present in pt with Sciatica

A

FALSE Antalgic gait is present (also in Morton’s neuroma)

10

A

Type C Fibers

11
Q

Which of these is not an S/sx of Saturday night palsy

Wrist drop
Paralysis
Sharp burning pain

A

None all are corect

11
Q

May lead to segmental demyelination

A

Saturday night palsy

11
Q

T or F
In Saturday night palsy the griping problem is due to the weakness of the wrist

A

FALSE weakness is not always the case, griping problems may be caused of the wrist drop
