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.
距骨体大骨囊肿常与骨软骨损伤相关。距骨骨囊肿可能是偶然的影像学发现。然而，当距骨广泛破坏时，存在病理性骨折和关节软骨损伤的风险，导致距下关节和踝关节持续肿胀和疼痛。开放清创和植骨通常需要广泛的软组织分离，甚至不同类型的踝关节截骨术才能适当暴露病变。本技术说明的目的是描述内镜刮除、微骨折以及用可注射骨移植替代物填充囊肿的技术。这种微创方法对正常软骨表面的破坏最小。
