Study Notes
Spinal Cord Injury Overview
- Neuro deficits are contingent upon the injury level.
- Injuries significantly impact motor and sensory functions.
Spinal Injury Statistics
- Nearly 50% of spinal cord injuries occur in individuals aged 16-30.
- Incidence is higher in males than females.
- Types of injuries:
- Incomplete tetraplegia: 40.6%
- Incomplete paraplegia: 18.7%
- Complete paraplegia: 18%
- Complete tetraplegia: 11.6%
Incomplete Spinal Cord Injuries
- Some motor or sensory function remains below the injury site.
Central Cord Syndrome
- Most frequently reported spinal cord injury.
- Common in elderly patients with minor extension injuries, often pre-existing cervical spondylosis.
- Characterized by greater motor deficits in upper extremities (UE) than lower extremities (LE), affecting hands more severely.
- Diagnostics:
- X-ray shows fractures/dislocations; flexion/extension views assess ligament status.
- CT reveals a narrowed spinal canal.
- MRI can display hematomas or compressions from bone or intervertebral discs.
Anterior Cord Syndrome
- Caused by direct compression of the anterior spinal cord or anterior spinal artery.
- Often results from flexion/compression injuries.
- Clinical findings include:
- Loss of motor function and pain sensation.
- Preservation of proprioception and vibratory sense.
Posterior Cord Syndrome
- Extremely rare condition.
- Exam results in loss of proprioception while preserving motor functions, pain sensation, and light touch.
Brown-Sequard Syndrome
- Results from cord hemotranssection, usually due to penetrating trauma.
- Key exam findings include:
- Loss of motor function and proprioception on the injury side.
- Loss of pain and temperature sensation on the opposite side.
Diagnostic Imaging Techniques
- CT and MRI are essential for assessing spinal cord injuries, including visualizing fractures, hematomas, and the overall integrity of the spinal canal.
Overview of Spinal Cord Injury
- Neuro deficits vary based on the level of spinal cord injury.
- Injuries are categorized as incomplete or complete.
Spinal Injury Statistics
- Nearly half of spinal cord injuries occur in individuals aged 16-30.
- Incidence is higher in males compared to females.
- Breakdown of injury types:
- Incomplete Tetraplegia: 40.6%
- Incomplete Paraplegia: 18.7%
- Complete Paraplegia: 18%
- Complete Tetraplegia: 11.6%
Incomplete Spinal Cord Injuries
- Retain some motor or sensory function below the injury site.
Central Cord Syndrome
- Most common spinal cord injury, often from minor extension in the elderly with preexisting cervical spondylosis.
- Motor deficits are more pronounced in upper extremities (hands over arms).
- Diagnosis through:
- X-ray: identifies fractures/dislocations.
- CT: reveals narrow spinal canal.
- MRI: shows hematomas or impingements from bone/discs.
Anterior Cord Syndrome
- Results from direct compression of the anterior cord or anterior spinal artery, often due to flexion/compression injuries.
- Clinical findings include motor and pain loss, while proprioception and vibratory senses remain intact.
Posterior Cord Syndrome
- Extremely rare occurrence.
- Characterized by loss of proprioception while motor skills, pain, and light touch remain preserved.
Brown-Séquard Syndrome
- Caused by hemisection of the spinal cord, commonly from penetrating trauma.
- Clinical examination shows a distinct pattern of sensory and motor loss depending on the side of injury.
Diagnostic Imaging Techniques
- X-ray, CT, and MRI play vital roles in diagnosing and assessing the extent and type of spinal cord injury.
