Large bone cyst of the talar body is frequently associated with an osteochondral lesion. The talar bone cyst can be an incidental radiologic finding. However, when the talus is extensively destroyed, there is a risk of pathologic fracture and damage to the articular cartilage, leading to persistent swelling and pain of the subtalar joint and ankle joint. Open debridement and bone grafting frequently requires extensive soft-tissue dissection or even different types of malleolar osteotomy for proper access to the lesion. The purpose of this Technical Note is to describes the technique of endoscopic curettage, nanofracture, and filling the cyst with injectable bone graft substitute. This minimally invasive approach has minimal disruption of the normal cartilage surface.
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.
