  • summary
    • Clay-shoveler fractures are avulsion-type spinous process fractures in the lower cervical or upper thoracic spine
    • Diagnosis is made using lateral radiographs of the cervical spine
    • Treatment usually consists of rest and pain control, as the injuries are mechanically stable
  • Epidemiology
    • Incidence
      • rare
    • Demographics
      • direct trauma to the posterior spinous process
      • indirect trauma
        • sudden muscular or ligamentous pull during flexion or extension
    • Anatomic location
      • most commonly C7, but can affect C6-T3
      • usually occurs midway between the spinous process tip and the lamina
    • Risk factors
      • laborers
      • racket or contact sports
      • motor vehicle accidents
  • Presentation
    • Symptoms
      • sudden onset of pain between the shoulder blades or at the base of the neck
      • reduced head/neck ROM
    • Physical exam
      • inspection
        • localized swelling
        • tenderness
        • crepitus
      • motion
        • document flexion-extension of cervical spine
      • neurovascular examination
  • Imaging
    • CT
      • views
        • fracture is best seen on lateral view
    • MRI
      • indications
        • not required in isolation
  • Complications
    • Chronic pain
    • Neck stiffness
  • Prognosis
    • Stable injury in isolation
    • Very rarely associated with neurologic injury
    • High union rate
