Osteoid osteoma: lower back pain combined with scoliosis.

Osteoid osteoma is a small benign bone tumor that is primarily localized in long bone; lumbar osteoid osteoma combined with scoliosis has rarely been reported. Here, we describe a 9-year-old boy who complained of back pain and scoliosis. He underwent nidus resection and did not experience complications or osteoid osteoma recurrence. His pain and scoliosis were relieved after the operation. The findings in this case indicate that resection of osteoid osteoma is an effective and safe method of treatment. The lumbar spine is the most common location of osteoid osteoma, which causes painful scoliosis. Nidus resection can provide relief of back pain and scoliosis.
