Аннотация
PURPOSE: Hemivertebrae, associated with a failure in the formation and fusion of vertebral body ossification nuclei, are a common cause of thoracic or lumbar scoliosis. A cervical location is rare and even rarer as a cause of cervical subluxation in flexion and extension (for which only one previous case has been found).
CASE REPORT: We report on the case of a 7-year-old female patient, who was examined for a cervical fusion defect, consisting of a posterior C4 hemivertebra and a left hemiblock from C5 to C7. After performing surgery consisting of a C4 corpectomy and anterior fixation with intersomatic graft and plate, adequate cervical stabilization with only a self-limiting left C6 brachialgia and ipsilateral Horner syndrome occurs in the postoperative period.
CONCLUSION: Posterior cervical hemivertebra associated with instability is a very rare finding. The anterior approach with corpectomy and anterior plate enables suitable stabilization.
