| | #REDIRECT[[Spinal cord injury]] |
| ANATOMY
| |
| # Doral column: proprioception, vibration and touch and decussate @ medulla | |
| # Lat corticospinal: voluntary motor and cross @ medulla. Upper extremity fibres more centrally, lower extremity fibres more lateral
| |
| # Ant spinothalamic: pain, temp. and light touch. Cross just one level above entry point to spinal cord.
| |
| | |
| ==Spinal Cord Syndromes==
| |
| ===COMPLETE TRANSECTION===
| |
| #higher lesions assoc w/ spinal shock &autonomic dysfunction
| |
| #sacral sparing (perianal sens, rectal tone, or toe flexor) excludes complete transection
| |
| | |
| ===ANTERIOR CORD===
| |
| #hyperflexion injury or blood supply prob (hypotension or aortic dissection)
| |
| #loss of motor (variable) and pain/temp
| |
| #proprioception, vibration and touch spared (Doral column)
| |
| | |
| ===CENTRAL CORD===
| |
| # hyperext of neck
| |
| #neuro deficit more pronounced in upper than lowe extremites
| |
| #Loss of distal upper extremity pain, tem and strength
| |
| | |
| ===BROWN-SEQUARD===
| |
| #ipsilateral loss strength, vibration, position
| |
| #contralteral loss pain and temp
| |
| | |
| ===CONUS MEDULLARIS/CAUDA EQUINA===
| |
| #Difficulty w/ urination (retention or incont) and sphincter control
| |
| #sexual dysf
| |
| #distal motor weakness
| |
| #saddle anesthesia
| |
| #(Conus Medullaris usually B/L sxs; Cauda Equina is usually unilateral)
