Central cord syndrome is a specific type of incomplete spinal cord injury that predominantly affects the cervical (neck) region of the spine. The condition occurs when damage to the central gray matter of the spinal cord disrupts the nerve pathways that control motor function and sensation. According to the National Spinal Cord Injury Statistical Center, central cord syndrome accounts for approximately 9% of all traumatic spinal cord injuries in the United States, making it the most common form of incomplete SCI. The hallmark characteristic of CCS is greater weakness in the upper extremities (arms and hands) compared to the lower extremities (legs), though the degree of impairment varies significantly among patients.
The underlying mechanism of central cord syndrome involves damage to the corticospinal tracts that carry motor signals from the brain to the muscles. In the cervical spinal cord, the nerve fibers controlling the arms are located more centrally, while those controlling the legs are positioned more peripherally. When trauma affects the central portion of the cord, arm function is disproportionately impaired. Many CCS patients also experience varying degrees of sensory loss, bladder dysfunction, and sexual dysfunction. Unlike complete spinal cord injuries that result in total paralysis below the injury level, central cord syndrome patients typically retain some motor and sensory function, though recovery patterns are highly variable and depend on factors including age, injury severity, and promptness of medical intervention.
