Cryoablation of osteoid osteoma with hip traction

Benign tumors of the acetabular roof are a therapeutic challenge. Percutaneous ablations avoid complicated surgery. These tumors are close to the cartilage and therefore there is a risk of damaging and causing chondropathy. We propose here the case of an osteoid osteoma treated by cryobablation associated with a hip traction with arthro-CT with warmed serum.
