Abstract:[Objective] To introduce the surgical technique and its preliminary outcomes of closed reduction and percutaneous cannu- lated screw fixation under temporary distraction by external frames for Sanders type II and III calcaneal fractures. [Methods] From October 2019 to December 2020, 16 patients received closed reduction and percutaneous cannulated screw fixation for Sanders type II and III calca- neal fractures. After the patients were placed in the healthy lateral decubitus position, a Schanze pin was inserted transversely through the calcaneus tuberosity and the talus respectively. A pair of external frames was attached with the pins on the medial and lateral sides. Distrac- tion was applied by the frames to correct varus and shorten deformities, and restore smooth articular surface and calcaneal shape. Finally, percutaneous cannulated screws were placed to fix the calcaneal fractures. [Results] All patients had surgical procedures performed suc- cessfully with no serious complications, such as vascular and nerve injury, whereas with operation time of (98.00±14.76) min. All patients got incision healing well without non- healing, delayed healing, or superficial and deep tissue infection. All patients had Gissane angle, Bohler angle, calcaneus length, calcaneus width and height recovered well on radiographs postoperatively, with the excellent and good rate of 93.75%. [Conclusion] The closed reduction and percutaneous cannulated screw fixation under bilateral distraction for calcaneal frac- tures has benefits of fewer postoperative incision complications, shortening preoperative waiting time, and achieve sound preliminary clini- cal outcomes.
