| | |
| ANATOMY
| |
| | |
| 1. Doral column: proprioception, vibration and touch and decussate @ medulla
| |
| | |
| 2. Lat corticospinal: voluntary motor and cross @ medulla. Upper extremity fibres more centrally, lower extremity fibres more lateral
| |
| | |
| 3. Ant spinothalamic: pain, temp. and light touch. Cross just one level above entry point to spinal cord.
| |

| ==Spinal Cord Syndromes==
| |
| | |
| | |
| I. COMPLETE TRANSECTION
| |
| | |
| -higher lesions assoc w/ spinal shock &autonomic dysfunction
| |
| | |
| -sacral sparing (perianal sens, rectal tone, or toe flexor) excludes complete transection
| |
| | |
| II. 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)
| |
| | |
| III. CENTRAL CORD
| |
| | |
| - hyperext of neck
| |
| | |
| -neuro deficit more pronounced in upper than lowe extremites
| |
| | |
| -Loss of distal upper extremity pain, tem and strength
| |
| | |
| IV. BROWN- SEQUARD
| |
| | |
| -ipsilateral loss strength, vibration, position
| |
| | |
| -contralteral loss pain and temp
| |
| | |
| V. 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)
