Osteoid osteoma and osteoblastoma of the spine.

Osteoid osteomas and osteoblastomas of the spine are rare primary spine tumors consisting of osteoblasts that produce osteoid and woven bone. They often involve the posterior spinal elements, with the thoracolumbar spine being the most common site of involvement. The authors review the clinical presentation, radiologic findings, and treatment in osteoid osteoma and osteoblastoma of the spine, with an emphasis on surgical management and outcomes in recent years.
