Treatment of a unicameral bone cyst of calcaneus with endoscopic curettage and percutaneous filling with corticocancellous allograft.
The surgical procedures for unicameral solitary calcaneal bone cysts have ranged from simple curettage and grafting to subperiosteal resection with internal fixation and grafting. In this article, an endoscopically assisted technique is proposed for the curettage of a simple calcaneal cyst that takes advantage of direct visualization of the cyst wall and contents and permits accurate assessment of the extent of the lesion. After curettage, percutaneous filling of the defect with corticocancellous allograft makes the technique a complete, minimally invasive surgical approach for this condition. The technique uses 2 lateral portals, one for viewing and the other for manipulation, both of which are created under fluoroscopic control. Once the cyst has been located, the 30 degrees arthroscope is used to evacuate fluid, after which more solid cyst contents are fragmented and removed. Thereafter, curettage of the inner surface of the cavernous cyst wall is performed. Finally, complete packing of the previously cystic cavity with crushed corticocancellous allograft is performed under endoscopic visualization and confirmed radiographically.
