Clinical Implications of the Rare Anomaly of a Cervical Hemivertebra over a Period of 30 Year

Objective: We stress out the rare anomaly of a cervical Hemivertebra associated with adjacent level radiculitis due to degeneration. Results: We present a case of a 58 years old female with spontaneous finding of a cervical hemivertebra at the level C5. The patient suffered from cervical nerve root compression syndrome at the level C6/7 at the convex side of the scoliosis. She was treated by a ventral cervical surgery with discectomy C6/7, nerve root decompression at the foraminal stenosis C7 and poly-methylmethacrylate fusion of this segment. Conclusion: The entity of a developmental anomaly of a hemivertebra lead to adjacent level disease which can cause radicular compression. The therapeutic strategy to choose in such cases can be difficult. In the present case we decided to perform a foraminotomy and fuse the adjacent level with poly-methylmethacrylate. We did not remove the hemivertebra.
