Question Answer
Causes of spinal cord compressiontumor, infection (chronic TB, staph), hematoma, disc disease (spondylosis), cystic lesion (syringomyelia)
Root compression Sxmuscle weakness, sensory deficit and LMN symptoms (wasting, atrophy, hypotonia, fasciculations, diminished reflexes)
Brown – Sequard syndromeipsilateral root/segmental signs, ipsilateral pyramidal type muscle weakness, contralateral pain/T sensation loss
Unilateral cord lesion SxBrown Sequard syndrome, motor deficit (dragging of the leg) UMN symptoms
Complete cord leison Sx spinal shock, motor deficit, sensory deficit, difficulty initiating misturition, incontinence, priapism, constipation, decreased power, flaccid limbs, bladder dilated
Central cord lesion segmental dmg Sxdysociated sensory loss, LMN weakness
Central cord lesion long tract dmg Sxcervical lesion- pain/T dysfunction in cape like distribution, Horners syndrome, sacral - sacral sparing
Spinal shockloss of sensation and motor paralysis with initial loss of recovery of reflexes
Lumbar disc prolapse Sxnumbness, paresthesia, loss of lumbar lordosis, scoliosis, restricted spinal movements, erector spinae spasm
reverse leg raising testassesment of L4 and higher compression
straight leg raising testassesment of L5/S1 compression
spondylolisthesisforward shift of vertebral body often asymptomatic
surgery indications in lumbar disc prolapsesevere unremitting leg pain, recurrent attacks of leg pain (repeated time loss from work), neurological deficit development
Cauda equina syndromeradicular pain, bowel/bladder dysfunction, numbness around anus, sexual disfunction, saddle anesthesia, legs weakness, achilles tendon reflex absent
Connus medullaris syndromeback pain, bowel/bladder dysfunction, impotence
