All the following are accepted treatment options for excision of an osteoid osteoma except
|A||Block excision of the nidus|
|B||Shaving of reactive bone till the nidus is encountered and then curetting the nidus|
|C||Radiotherapy with Brachy therapy using a caesium needle|
|D||Introduction of a k wire into the nidus after CT localization and then introduction of a Biopsy punch over the wire|
Radiotherapy with Brachy therapy using a caesium needle
a. To effect a cure in causes of osteoid osteoma the entire nidus has to be removed. Most authors suggest block resection of the nidus but this results in an increased risk of fracture when the lesion is in a cortical bone.
b. The other method is to shave the reactive bone till nidus is encountered and the nidus is curetted. Intraoperative localization of the nidus is possible by preop injection of Tc methylene diphosphonate and a sterile Geiger counter.
