The use of battery-powered drill facilitates access to the osteoid osteoma nidus in cases where excess reactive new bone formation is present. Biopsy needle can be used for channel creation during the access offering at the same time the possibility to extract bone samples.
RFA under CT guidance is a safe and efficient technique for the treatment of painful intra-articular osteoid osteoma. Imaging guidance, extra-articular access through normal bone and exact positioning of the needle-electrode inside the nidus facilitate safety of the technique and prevention of damage to the articular cartilage.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
