Feasibility of Percutaneous Image-Guided Combined Treatment of Symptomatic Bone Cyst Using Cryoablation and Bone Graft Substitute.

Purpose: To describe the feasibility and technique of percutaneous image-guided combined treatment of bone cyst (BC) using cryoablation and bone graft substitute injection.

Materials And Methods: Between July 2019 and January 2022, six consecutive patients (ages between 16 and 33 years) with symptomatic BC in pelvic and lower extremity bones underwent percutaneous image-guided combined treatment using cryoablation and bone graft substitute. To induce bone mineralization as early as possible, the cyst cavity was filled with bone graft substitute.
