En bloc (Open) Excision in the Treatment of Osteoid Osteoma

Abstract

Background: The standard treatment for osteoid osteoma (OO) is conventional (en bloc) open excision. The study aimed to discuss the clinical outcomes and complications of the conventional (en bloc) open excision.
Methods: Twenty-five patients with OO were treated with (en bloc) open excision during a period from January 2015 to June 2020. The clinical ?ndings and radiological investigations and the operative data were recorded. Radiological assessment was based mainly on plain X-rays. The mean age of patients was 18 (range 16-32) years and the follow-up was ranged 3-5 years. The bone excised was sent for histopathology.
Results: Pain improved in 20 (80%) patients at the ?rst week postoperatively. In five patients (20%), the improvement gradual-onset during the ?rst 6 months. The complication included increased pain, foot drop, proximal fibula, neurapraxia and hematoma. There was no OO recurrence, no pathological fracture, and no postoperative infection.
Conclusions: Open (En bloc) excision of OO has the risk of increased morbidity and complications. When recommended, there are must be unavailable facilities and equipment to perform the percutaneous procedures.
