Central Cord Syndrome

Spine

Overview

Central Cord Syndrome (CCS) is a traumatic spinal cord injury characterized by greater loss of motor function and sensation in the upper extremities compared to the lower extremities, typically resulting from hyperextension injuries or hemorrhagic contusion in the cervical spine. It represents the most common incomplete spinal cord injury pattern and can occur with or without vertebral fracture. Prognosis varies depending on age, severity of initial injury, and presence of associated spinal pathology.

Pathophysiology

Central Cord Syndrome results from a disproportionate injury to the central gray matter and central white matter tracts of the cervical spinal cord. The mechanism typically involves hyperextension trauma causing cord compression, ischemia, and hemorrhagic contusion. The anatomical organization of corticospinal tracts in the cervical cord—with upper limb fibers located centrally and lower limb fibers peripherally—explains the characteristic pattern of upper extremity greater dysfunction than lower extremity. Secondary injury mechanisms include edema, inflammation, and microvascular disruption leading to progressive neuronal death and cavitation.

Patient Education

Early mobilization, structured rehabilitation, and realistic goal-setting based on neurological recovery patterns are essential, as many patients with Central Cord Syndrome achieve significant functional recovery, particularly in lower extremity function.

Typical Presentation

Site

Cervical spinal cord with central distribution; symptoms predominantly affecting bilateral upper extremities (shoulders, arms, hands) with relative sparing of lower extremities and perineum

Quality

Weakness, loss of dexterity, numbness and tingling (paresthesias), loss of fine motor control, variable pain ranging from dysesthetic to hyperesthetic

Intensity

Highly variable; motor impairment typically severe in acute phase with moderate to severe functional limitation; pain intensity ranges from mild to severe depending on associated injuries

Aggravating

Upper extremity use and fine motor tasks, cervical spine movement particularly extension, activities requiring grip strength or precision, fatigue

Relieving

Rest, immobilization of cervical spine acutely, anti-inflammatory medications, physical support and bracing, lower extremity movement and weight-bearing

Associated

Bladder and bowel dysfunction (variable), lower extremity weakness (typically mild), preserved sacral sensation (often), pain in upper extremities and neck, spasticity (developing over weeks to months), loss of temperature sensation, preserved walking ability in many cases

Orthopaedic Tests

Upper extremity motor strength testing

Procedure

Assess bilateral hand grip strength, wrist extension, elbow flexion, and shoulder abduction using manual muscle testing (MMT) grades 0–5. Compare upper to lower extremity strength.

Positive Finding

Disproportionate weakness in upper extremities relative to lower extremities; grip strength typically more affected than proximal muscles

Sensitivity / Specificity

Unknown / Unknown

Schneider et al., 1954, Journal of Neurosurgery; Bunge et al., 2008, Journal of Neurosurgery

Interpretation

Central cord syndrome characteristically presents with 'inverted' motor loss (upper > lower). This pattern reflects the anatomical arrangement of corticospinal tract fibres, with cervical fibres positioned peripherally in the cord. Positive finding strongly supports CCS diagnosis.

Sensory level testing (pain and temperature)

Procedure

Using pinprick or temperature sensation (ice), map bilateral dermatomes from C2 downward. Document the level at which sensation returns to normal bilaterally.

Positive Finding

Loss of pain and temperature sensation in a 'cape-like' distribution (bilateral upper extremities and upper torso); lower extremities spared. Sensory level typically 1–2 dermatomes above motor level.

Sensitivity / Specificity

Unknown / Unknown

Schneider et al., 1954, Journal of Neurosurgery; Bunge et al., 2008, Journal of Neurosurgery

Interpretation

The dissociated sensory loss (loss of pain/temperature with preservation of proprioception/vibration) reflects selective damage to crossing spinothalamic tract fibres in the central cord. This pattern is pathognomonic for CCS.

Lower extremity motor and sensory preservation

Procedure

Test lower extremity strength (hip flexion, knee extension, ankle dorsiflexion) and assess gross proprioception/vibration sensation in feet bilaterally.

Positive Finding

Preserved or near-normal lower extremity motor and sensory function despite significant upper extremity deficits

Sensitivity / Specificity

Unknown / Unknown

Schneider et al., 1954, Journal of Neurosurgery; Bunge et al., 2008, Journal of Neurosurgery

Interpretation

Preservation of lower extremity function despite upper extremity paralysis is a cardinal feature of CCS and helps differentiate it from complete spinal cord injury or anterior cord syndrome. Reflects peripheral location of damage in the cord.

Rectal examination (sacral sparing assessment)

Procedure

Perform digital rectal examination to assess perianal sensation (pinprick) and rectal sphincter tone; test voluntary external anal sphincter contraction.

Positive Finding

Preserved perianal sensation and external anal sphincter function despite upper extremity paralysis

Sensitivity / Specificity

Unknown / Unknown

Bunge et al., 2008, Journal of Neurosurgery; American Spinal Injury Association (ASIA) Impairment Scale Classification

Interpretation

Sacral sparing (preserved perineal sensation and anal sphincter control) indicates incomplete spinal cord injury and predicts better neurological recovery. Critical prognostic finding in CCS.

Cervical spine imaging correlation (MRI)

Procedure

Review cervical MRI to identify central cord signal abnormality (T2-weighted hyperintensity) and correlate with clinical presentation. Note hemorrhage, oedema, or structural lesion.

Positive Finding

Central cord T2 hyperintensity/signal change on MRI in region corresponding to clinical level; may show associated fracture, ligamentous injury, or cord haemorrhage

Sensitivity / Specificity

Unknown / Unknown

Bunge et al., 2008, Journal of Neurosurgery; Fehlings et al., 2017, Global Spine Journal

Interpretation

MRI provides anatomical confirmation of central cord pathology and helps rule out alternative diagnoses (anterior cord, complete injury, Brown-Séquard). Imaging combined with clinical pattern solidifies diagnosis.

ASIA Impairment Scale (AIS) assessment

Procedure

Perform standardized neurological examination using ASIA protocol: assess motor (10 upper, 10 lower extremity key muscles) and sensory (pin/light touch in 28 dermatomes) to assign grade A–E.

Positive Finding

AIS Grade D or E with disproportionate upper extremity weakness relative to lower extremity; preservation of sacral segments (S4–S5)

Sensitivity / Specificity

Unknown / Unknown

Kirshblum et al., 2011, Journal of Spinal Cord Medicine; American Spinal Injury Association Revised Standards

Interpretation

ASIA grading standardizes severity assessment and prognosis. CCS typically grades AIS C–D; the pattern (upper > lower) and sacral preservation are key diagnostic features. Allows serial monitoring and comparison.
