Osteoid osteoma and Osteoblastoma Specialist Surgeon Singapore 

Precision Ablation and Minimal Access Resection

We manage osteoid osteoma as a challenge of localization and targeted resolution. Under the clinical direction of Dr. Saminathan Suresh Nathan, our protocols focus on the definitive elimination of the "nidus"—the source of pain—while sparing healthy bone. By utilizing thirty years of surgical discernment, we employ radiofrequency ablation (RFA) or high-resolution guided excision to ensure immediate pain relief and rapid return to function. The osteoid osteoma and osteoblastoma are histologically identical and distinguished by osteoblastoma being bigger (greater than 2 cm). They are benign conditions that unfortunately are poorly tolerated as they cause a lot of pain. They uniquely become painless after treatment with non-steroidal anti-inflammatory drugs which unfortunately cannot be given long-term due to their side -effects. Treatment involves curettage and cementation and prognosis is excellent.

Surgical Considerations

• Nidus Localization: High-resolution CT-guided mapping to ensure the precise destruction of the lesion.

• Minimal Morbidity: Utilizing percutaneous techniques where possible to minimize soft tissue disruption.

• Mechanical Preservation: Strategic planning to avoid structural weakening of long bones during the ablation process.

Figure. This 8 year-old boy had a right proximal humerus osteoblastoma. It was mistaken for an osteosarcoma and had been planned for chemotherapy. We were consulted and gave a second opinion of an osteoblastoma. This was curretted and cemented and the patient has since grown to adulthood without incident.
