Talar bone cysts can develop as a result of osteochondral lesions of the talus. This can be a source of deep ankle pain. Open debridement and bone grafting of the bone cysts requires extensive soft tissue dissection and malleolar osteotomy. Removal of normal cartilage of the talus is frequently required to approach the bone cysts. Alternatively, the cysts can be grafted arthroscopically with minimal disruption of the normal cartilage surface. The key to success is careful preoperative planning with a computed tomogram of the ankle. Bone cyst of the posterior half of the talar body can be grafted via posterior ankle endoscopy. Bone cyst of the anterior half of the talar body can be debrided and grafted via anterior talar osseous portals. The purpose of this technical note is to describe a minimally invasive approach of curettage and bone grafting of the talar bone cysts with preservation of the articular surfaces.
距骨囊肿可由距骨的骨软骨损伤发展而来。这可能是踝关节深部疼痛的一个原因。骨囊肿的开放清创和植骨需要广泛的软组织解剖和踝关节截骨术。为了接近骨囊肿，通常需要去除距骨的正常软骨。或者，可以通过关节镜对囊肿进行植骨，对正常软骨表面的破坏最小。成功的关键是术前用踝关节计算机断层扫描进行仔细规划。距骨体后半部的骨囊肿可通过后踝关节镜进行植骨。距骨体前半部的骨囊肿可通过距骨前骨门进行清创和植骨。本技术说明的目的是描述一种在保留关节面的情况下对距骨囊肿进行刮除和植骨的微创方法。
