Efficacy of Curetage Procedure in Osteoid Osteomy Treatment

In 11 patients with osteoid osteoma localized in long bone of limbs, under general anesthesia (in one case spinal), we burred the sclerotic bone, curettaged the nidus, and excised a thin border of nidus by Hollow mill. The patients were observed clinically and radiologically with an average of 2 years and 11 months of follow-up (at least one year). There wasnot any recurrence and this procedure was curative in all patients. There was no complication except a postoperative pathological bone fracture. Trauma and technical error in surgery were considered as the main causes of the fracture. Internal fixator device (in 1 case), bone graft (in 1 case), and postoperative physiotherapy (in 1 case) were used. The mean duration of total hospital stay was 4.8 days (range 2-19) and the mean duration of postoperative hospital stay was 3.5 days (range 1-11). The mean duration of absence from work was 43 days (range 3-185). By the lesions in the lower extremity the mean duration of no-weight-bearing was 13.8 days (range 0-30) and of partial-weight-bearing was 35.8 days (range 14-60). Postoperatively, the patients returned to normal life activity, after a mean duration of 7 weeks.
