Technical Note of Arthroscopic Subtalar Arthrodesis Using Posterior Portals - Operative Technique -

후방 삽입구를 이용한 관절경적 거골하 관절 유합술- 수술 방법-

A posterior 3-portal arthroscopic approach with the patient in the prone position provides a novel and optimal approach for isolated subtalar arthrodesis. This approach facilitates access to the posterior talocalcaneal facet and facilitates safe access with regard to the posteromedial neuromuscular bundle. The technique involves prone positioning, establishment of two posterolateral portals and one posteromedial portal, arthroscopic posterior talocalcaneal facet debridement, percutaneous morcellized bone grafting and internal screw fixation. Preliminary results have shown high patient satisfaction, an excellent fusion rate and less postoperative morbidity than open subtalar arthrodesis.
