A Case of the Aneurysmal Bone Cyst on the Whole 5th Cervical Vertebra

ABSTRACT

Aneurysmal bone cysts are uncommon bony lesions that usually occur in the metaphyseal region of the long bones in adolescents. Approximately 20% of the aneurysmal bone cysts occur in the spine, predominantly in the lumbar region. These lesions commonly arise from the posterior elements(ex, spinous process, laminae) and occasionally invade the pedicles and the vertebral body. We experienced a case of aneurysmal bone cyst on the entire 5th cervical vertebra(vertebral body, pedicle, laminae, spinous process and transverse process). We perfomed C5 corpectomy and fusion with ORION plate and autologous bone graft on C4-5-6, and C5 total laminectomy with gross total mass removal and posterior fusion with Heid lateral plate system and autologous bone graft and wiring on C4-5-6. The patient showed good recovery. We report a rare case of aneurysmal bone cyst on the whole involved 5th cervical vertebra
