Brown-Sequard Syndrome (BSS)
Brown-Sequard Syndrome results from an injury to one half of
the spinal cord as seen in penetrating injuries. The spinothalamic tract fibers
cross the midline below the level of the lesion resulting in contralateral loss
of pain and temperature sensation. The posterior column and the corticospinal
tracts carry vibration, position, light touch sensation, and motor function
that are lost from the ipsilateral side of the body. The prognosis is usually
good. 90% of the patients recover. If the patient has a wound on the right
side, the patient will feel it on the left side. It is a hemisection lesion.
There is loss of vibratory, light touch and motor on the same side while pain
and temperature is lost on the other side.
