Fracture Risk With Pressurized-Spray Cryosurgery

Forty-two patients treated with curettage, burring, direct pressurized cryotherapy, and bone grafting or cementation were retrospectively reviewed. There were no pathologic fractures in this study group, compared with a 17% fracture rate in recent studies using the “direct pour” technique. Direct pressurized cryotherapy was used in 3 separate freezing cycles in each case. This approach may significantly reduce the risk for fracture compared with historical controls using the direct-pour technique.
