Acute cervical fracture or congenital spinal deformity?
OBJECTIVE
There are few reports of developmental or congenital cervical spinal deformities. Such cases may be mistaken for traumatically induced fractures, and additional treatment may ensue.


METHODS
A retrospective analysis was performed to identify patients with congenital cervical spine deformities. These patients were matched with a confirmed traumatic spinal fracture population with similar demographic features. Patients were analyzed for age, gender, imaging findings (plain roentgenograms including dynamic flexion and extension views, computed tomography scan, and MRI), neurologic status, and subjective complaints of pain.


RESULTS
Thirty-six individuals were included in the final analysis, 7 with congenital abnormalities and 29 with radiographically confirmed traumatic injuries. Patients with congenital abnormalities had significantly less soft-tissue swelling compared with the population with traumatic fractures (P < 0.001). Furthermore, those with congenital defects presented with lesser degrees of vertebral subluxation (0.29 mm vs 7.24 mm) (P < 0.0001) and without neurologic deficits (P < 0.0001).


CONCLUSIONS
Congenital abnormalities, though rare, can be mistaken for traumatic fractures of the spine. Physicians should note any evidence of soft-tissue swelling, neurologic deficits, degree of subluxation, and radiographic evidence of pedicle absence because these characteristics often provide insight into the specific etiology of the observed spinal deformity (congenital vs traumatic).
