Summary
Subacute instability of the cervical spine is a newly identified condition where instability develops within 3 weeks of injury, despite normal initial imaging. Early detection is crucial for timely treatment and preventing permanent damage.
Area of Science:
- Orthopedics
- Neurosurgery
- Radiology
Background:
- Cervical spine injuries can present with subtle instability.
- Initial radiographic evaluations may not detect all forms of cervical spine trauma.
Purpose of the Study:
- To define and describe subacute instability of the cervical spine.
- To report cases and propose an evaluation algorithm for this condition.
Main Methods:
- Retrospective review of six patients with subacute cervical spine instability.
- Analysis of injury mechanisms and radiographic findings.
- Development of a diagnostic algorithm for cervical trauma.
Main Results:
- Six patients developed cervical instability within 3 weeks of injury, with initial normal radiographs.
- Diagnoses included facet dislocations, perched facets, and extension subluxations.
- Neurologic deficits were noted in affected patients.
Conclusions:
- Subacute instability of the cervical spine is a distinct clinical entity.
- Prompt recognition and treatment are essential to prevent fixed deformities.
- The proposed algorithm aids in evaluating patients with normal initial cervical spine radiographs.
