Radiofrequency ablation for non-spinal osteoid osteomas in 557 patients.

Objectives: To present the results of biopsy and computed tomography (CT) guided radiofrequency ablation (RFA) for non-spinal osteoid osteomas, and compare the results before and after procedural modifications.

Methods: We retrospectively studied 557 patients with non-spinal osteoid osteomas treated with biopsy and CT-guided RFA. In 68 patients we used 3-mm CT at 2-mm intervals, 19 G/5-mm active tip electrodes, and one 4-minute ablation at 90-93°C.

Imaging of vascularized fibula autograft placed inside a massive allograft in reconstruction of lower limb bone tumors.

Objective: Bone allografts and vascularized fibula autografts were combined (the fibula inside the massive allograft) for skeletal reconstruction in a homogeneous group of patients. To verify the biologic behavior of the grafts, we followed the series using conventional radiography and CT analysis.

Materials And Methods: Twenty-four patients with bone tumors had intercalary segments of tibia or femur reconstructed and were followed up for 36-120 months.
