Osteoid osteoma - treatment?

What is the surgical procedure for the removal of an osteoid osteoma of the hip?

Osteoid osteoma is a benign lesion of bone with no malignant potential. This type of tumour accounts for approximately 10% of benign bone tumours. The commonest location for an osteoid osteoma is the upper end of the femur or thighbone. The tumour has a number of very distinctive symptoms; the pain is typically worse at night, the pain disappears within 20 minutes of taking an aspirin or other form of non-steroidal anti-inflammatory drug and consuming alcohol aggravates the pain. Osteoid osteoma has a distinctive radiological appearance, which renders it easily diagnosable with a standard x-ray. These tumours do not grow or expand and it is possible for them to regress or remain dormant. There are several treatment options. The tumour can be surgically excised with the residual cavity being filled with grafted bone chips. Alternatively the diseased area can be ablated by using laser, radiofrequency or thermocoagulation while using a CT scanner to visualise the tumour. The nature of the treatment would require detailed specialist assessment with each case being treated on its own individual merits. This is a scenario where each case is treated individually. In other words there is no “one size fits all” approach to treatment.
