Spinal cord injury syndromes

Central cord syndrome
Incomplete spinal cord injury
Weakness in the arms with relative sparing of the legs with variable sensory loss
Ischemia, hemorrhage, or necrosis involving the central portions of the spinal cord
May be seen in recovery from spinal shock due to prolonged swelling around or near the vertebrae, causing pressure on the cord. Can be transient or permanent.

Anterior cord syndrome
Associated with flexion type injuries to the cervical spine
Damage to the anterior portion of the spinal cord and/or anterior spinal artery
Below the level of injury motor function, pain sensation, and temperature sensation are lost
Touch, position and vibration are intact

Posterior cord syndrome
Posterior portion of the spinal cord and/or posterior spinal artery
Loss of proprioception and epicritic sensation (e.g. stereognosis, graphesthesia) below the level of injury
Motor, pain, and sensitivity to light touch are intact

Brown-Séquard syndrome
Hemisectioned or lateral injury side (penetrating trauma)
Ipsilateral side loss of motor function, proprioception, vibration, and light touch
Contralateral side loss of pain, temperature, and crude touch sensations
