Central cord syndrome (CCS) is an acute cervical spinal cord injury (SCI), characterized by disproportionately greater motor impairment in upper compared to lower extremities, bladder dysfunction, and variable degree of sensory loss below the level of injury.
CCS most often occurs after hyperextension injury in an individual with long-standing cervical spondylosis. Motor impairment that results is from the pattern of lamination of the corticospinal and spinothalamic tracts in the spinal cord. Sacral segments are the most lateral with lumbar, thoracic, and cervical components arranged somatotopically, proceeding medially toward the central canal.
The deficit in motor function is more severe in the upper extremities than in the lower extremities, and most profound in the intrinsic musculature of the hand. The extent of sensory-function deficit varies, as does the degree of bowel and bladder dysfunction. A spontaneous improvement in neurologic function over time is the rule; residual neurologic dysfunction is common, however, and appears to depend on the severity of the initial injury.
