- Discussion:
- type of hyperflexion avulsion injury - fx of spinous process at base;
- they are caused by sudden exertions of the muscular attachments, and can be caused by flexion injuries;
- most common at C7 > C6 > T1
- considered stable;
- if avulsion frx is not limited to spinous process but extends into lamina, there is greater potential for spinal cord injury;
- be sure to rule out associated facet frx or unilateral jump facet;
- Treatment:
- once presence of segmental instability has been ruled out, Clay shoveler's fractures can be treated non operatively;
- hard collar should be worn for at least 10 days or until good flexion-extension views can be obtained;
- afterwards, cervical collar is worn until good callus is present
