Classification/Level of Lesions: Complete Lesion: Total loss of sensory and motor functions. Neurogenic (spinal) shock evidenced by marked hypotension, bradycardia, and loss of reflexes. Flaccid paralysis of the bladder with urinary retention. Flaccid paralysis of the bowel with paralytic ileus. Loss of perspiration below the level of injury. Incomplete Lesions: Types: Brown-Séquard Syndrome: Occurs from hemisection of the spinal cord, usually caused by penetrating trauma. Ipsilateral Side: Loss of sensation. Lack of superficial reflexes (e.g., clonus, Babinski's sign). Loss of proprioception, kinesthetic sensation, and vibration sense. Contralateral Side: Loss of sensation of pain and temperature. Anterior Cord Syndrome: Occurs due to flexion injuries to the cervical region or damage to the anterior spinal artery. Results in: Loss of motor function. Loss of sensation of pain and temperature. Central Cord Syndrome: Results from hyperextension injury to the cervical region, often associated with congenital or degenerative narrowing of the spinal canal. Affects the central portion of the spinal cord, causing: Varying degrees of sensory impairment, often less severe than motor deficits. Normal sexual, bowel, and bladder functions. Posterior Cord Syndrome: Extremely rare. Results in deficits of function served by the posterior column while preserving motor function, pain, and touch sensation.
