Study Notes

Areflexia and Spinal Shock

Areflexia may occur initially after spinal injury; not all reflexes will be absent.
Spinal shock resolves with the return of the bulbocavernosus reflex in supra-sacral lesions.
Consider spinal shock if the patient shows hypotension combined with bradycardia.

Partial Spinal Cord Injury Syndromes

Anterior Cord Syndrome: Characterized by loss of motor power and reduced pain and temperature sensation below the injury site.
Central Cord Syndrome: Greater impact on arm function compared to leg function.
Posterior Cord Syndrome: Lost proprioception below the level of the injury.
Brown-Sequard Syndrome: Weakness and proprioception loss on the injured side; normal motor and temperature sensation on the opposite side.

Radiological Investigations

Cervical Spine: Initial imaging includes a lateral X-ray showing C7/T1. Anterior-posterior (AP) views, open mouth, and potentially swimmers views are necessary.
Interpret X-ray results using ABC rules: Alignment, Bones, Cartilage, and Soft tissues.
CT Scans: Helical CT surpasses conventional X-rays in sensitivity and specificity, particularly for occipito-cervical and cervico-thoracic junctions.

Thoracic and Lumbar Spine

Double-level injuries occur in 10-20% of cases, necessitating evaluation of spinal stability.
Various classification systems exist; AO spine classification revised in 2013, while TLICS (published November 2013) remains widely adopted.

Further Investigations

Mandatory ATLS guidelines recommend chest X-ray, pelvic view, and assessment of injured areas.
CT and MRI scans assist in surgical management and diagnostics but rarely change treatment strategies.

Surgical Management

STASCIS Study (Fehlings et al., 2013): Indicates decompression within the first 24 hours post-SCI enhances neurological outcomes.
Spinal Recovery: Analysis from Sygen database shows 30% of patients recover to incomplete SCI, and after a year, up to 70% recover at least one motor level, with 30% regaining two or more levels.
Both conservative and surgical management should be available at specialized spinal cord injury centers.

Early Management and Complications

Respiratory Complications: Common in high-level spinal cord injuries due to intercostal paralysis and limited respiratory function.
In paraplegic patients, rib fractures and pulmonary contusions may complicate respiratory issues.
Regular physiotherapy and monitoring of respiratory parameters (oxygen saturation, vital capacity, blood gases) are essential.
A vital capacity below 15ml/kg and rising PCO2 suggest respiratory failure, which may require ventilatory support.

Cardiovascular Complications

Post-traumatic shock often arises from hemorrhage related to associated injuries and requires prompt treatment.
Recognition of sympathetic nervous system involvement is critical in managing traumatic tetraplegia.
