a Landmarks for skin incisions were identified 1) the lateral malleolus, 2) the Achilles tendon, and 3) the incision for the MIPO group. b A periosteum elevator was used to create a lateral calcaneus subfascial channel. c Satisfactory anatomical reduction of the calcaneum is achieved with a Steinmann pin under C-arm fluoroscopy intraoperatively. d A periosteum elevator was inserted in the calcaneum and placed under the posterior articular surface. e Under C-arm fluoroscopy, the posterior articular surface was directly reduced by leverage with a periosteum elevator. f A pre-bent calcaneus plate was prepared. g The plate and screw were secured into place. h The rubber drains were inserted and the incision was closed in a layered fashion
