Spinal surgery Flashcards
What is the difference between radiculopathy and myelopathy?
radiculopathy= nerve root compression myelopathy= spinal cord compression
What is the pathophysiology of cervical myeloradiculopathy
disc protrusion, facet joint degeneration, osteophyte formation to compress neural structures
Does radiculopathy cause UMN or LMN signs?
LMN
What pain is typical in radiculopathy pain?
severe shooting arm pain
Does myelopathy present with UMN or LMN symptoms?
UMN
What is Hoffman’s sign?
loosely holding the middle finger and flicking the fingernail downward, allowing the middle finger to flick upward reflexively. A positive response is seen when there is flexion and adduction of the thumb on the same hand= Babinski reflex in upper limb

late signs, irreversible
Investigations for cauda equina syndrome?
