Study Notes
Incomplete Spinal Cord Transection
- Spinal cord injury causes alterations in neuronal transmission
- Dysfunction depends on segmental level, injury type, and severity of transection
- Categories include complete transection (loss of function below injury), partial transection (categorized by syndromes), including central cord, anterior cord, and Brown-Séquard
- SCI can result in complications such as ischemia, hemorrhage, necrosis, and edema
- Varying degrees of loss of function
- Cervical injury (C1-C2) leads to quadriplegia, impacting involuntary function, body temperature regulation, and potentially respiratory support
- C4 or above injuries preserve upper body function
- Thoracic injuries (T1) affect trunk and lower body control — resulting in paraplegia
- Lumbar and sacral level injuries result in loss of lower extremity control
- Diagnosis involves physical exam (cognitive, motor, sensory function) for conscious patients or diagnostic testing (imaging: X-ray, CT, MRI, myelography) for those with neck pain, weakness, or unconsciousness
- Treatment includes immediate immobilization of the spine to prevent further damage, followed by pharmacologic intervention (corticosteroids to prevent inflammation), and surgical intervention (fracture correction and spinal cord decompression)
- Full recovery is rare, impairments are typically permanent, and currently, there's no cure
