2. Ipsilateral motor and proprioception deficits, contralateral pain and temperature deficits.
3. Anterior cord syndrome involves the anterior 2/3 of the spinal cord and preserves the posterior columns. It results from anterior spinal artery lesions, direct injury to the anterior cord, bone fragments, retropulsed disc, polyarteritis nodosa, angioplasty, aortic and cardiac surgery, embolism.
4. Loss of motor function (variable), loss of pain and temperature sensation. Preserved proprioception and light touch.
5. Loss of proprioception with variable preservation of motor function.
