Spinal Cord Injury ll: Pathophysiology01:14

Spinal Cord Injury ll: Pathophysiology

Spinal cord injury progresses through two interconnected phases: primary injury and secondary injury.Primary InjuryPrimary injury happens at the moment of trauma and involves immediate mechanical damage to the spinal cord.Compression happens when broken vertebrae, herniated discs, or accumulating blood (such as a hematoma) press directly against the spinal cord, distorting its normal shape and function. In cases of contusion, the cord is bruised by a blunt force (like penetrating injuries or...
Secondary Spinal Cord Injury llI: Pathophysiology01:25

Secondary Spinal Cord Injury llI: Pathophysiology

Early Ischemia and Ionic ImbalanceWithin minutes of spinal cord injury, a secondary cascade begins, progressing over hours to weeks. Vascular damage reduces blood flow, causing ischemia and mitochondrial dysfunction. ATP depletion leads to ion pump failure, membrane depolarization, sodium influx, potassium efflux, and water accumulation, resulting in cellular swelling. Increased intracellular calcium further disrupts mitochondria and accelerates cellular injury.Excitotoxicity and Neuronal...

Area of Science:

  • Trauma Surgery
  • Public Health
  • Epidemiology

Background:

  • Growing incidence of electric scooter (e-scooter) related injuries necessitates comprehensive analysis.
  • Increasing publications highlight the need for a systematic review and meta-analysis of e-scooter accident data.

Purpose of the Study:

  • To synthesize findings on injury types, severity, clinical care, accident mechanisms, risk factors, and patient demographics in e-scooter accidents.
  • To provide a quantitative overview of the e-scooter injury landscape.

Main Methods:

  • Systematic literature search across PubMed, EMBASE, and Medline for quantitative clinical studies (07/2019-07/2024).
  • Inclusion of studies reporting e-scooter injuries in emergency department patients.
  • Proportional and arithmetic mean meta-analyses for summarizing injury frequencies and continuous parameters.

Main Results:

  • Head and face injuries are most common (42.1%), followed by upper extremity injuries (40.1%).
  • Extremity fractures affect 25.7% of patients; severe traumatic brain injuries occur in 2.3%.
  • Overall severe injuries (ISS ≥ 16) are reported in 2.8% of e-scooter patients.

Conclusions:

  • Head, face, and upper extremity injuries dominate emergency department visits post e-scooter accidents.
  • A significant proportion (25.7%) of patients sustain extremity fractures.
  • Severe injuries remain infrequent, affecting less than 3% of those involved in e-scooter incidents.
