Osteoid osteomas of the spine

Area of Science:

• Orthopedics
• Radiology
• Oncology

Background:

• Spinal osteoid osteomas are benign bone tumors that can cause debilitating pain.
• Clinical presentation often includes spinal pain, with radicular pain and scoliosis in approximately half of cases.
• Diagnostic challenges exist, as conventional spinal imaging may be insufficient.

Purpose of the Study:

• To review the clinical presentation, diagnosis, and management of spinal osteoid osteomas.
• To highlight the diagnostic utility of bone scintigraphy in these cases.
• To emphasize the effectiveness of surgical resection for pain relief.

Main Methods:

• Review of seven patients with spinal osteoid osteomas.
• Comprehensive literature review of 110 additional cases.
• Analysis of diagnostic imaging modalities including radiography, tomography, bone scanning, and computed tomography.
• Evaluation of treatment outcomes following surgical removal of the tumoral nidus.

Main Results:

• Spinal pain is a universal symptom; radicular pain and scoliosis occur in about 50% of patients.
• Bone scanning demonstrates 100% sensitivity for detecting spinal osteoid osteomas.
• Spinal computed tomography, guided by bone scan findings, precisely localizes the lesion.
• Surgical excision of the tumoral nidus results in pain remission in over 95% of cases.

Conclusions:

• Bone scintigraphy is essential for diagnosing spinal osteoid osteomas, especially in young patients with spinal or radicular pain.
• Misdiagnosis as a lumbar protruded disc is possible, underscoring the need for appropriate imaging.
• Complete resection of the osteoid osteoma nidus is a highly effective treatment for pain relief.
