Radiographic Analysis of Intra-articular Fractures of the Calcaneus in patients undergoing Minimally Invasive Surgical Treatment in a Tertiary Hospital.

 This paper aims to evaluate patients with articular calcaneal fractures treated with a minimally invasive surgical technique between January 2015 and August 2016, with emphasis on radiographic results.  Retrospective study of 49 patients with 64 displaced calcaneal fractures treated with open reduction by minimal lateral access to the subtalar joint and minimal fixation. Pre- and postoperative radiographic studies were performed to measure the angles of Böhler and Gissane.  The average angle of Böhler before surgery was 2.5°, increasing to an average value of 25.3° after the minimally invasive surgical treatment. The average angle of Gissane before surgery was 136.3°, decreasing to an average value of 114.3° after the procedure.  The minimally invasive surgical technique improves the radiographic parameters of intra-articular calcaneal fractures, with appropriate anatomical restoration of anatomical shape.
