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

Objective 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. Methods 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. Results 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. Conclusion The minimally invasive surgical technique improves the radiographic parameters of intra-articular calcaneal fractures, with appropriate anatomical restoration of anatomical shape.

Abstract Objective 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. Methods 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. Results The average angle of Böhler before surgery was 2.5º, increasing to an average value of 25.3º after the minimally invasive surgical treatment.

Resumo Objetivo Avaliar pacientes com fraturas intra-articulares de calcâneo tratados entre janeiro de 2015 e agosto de 2016 com técnica cirúrgica minimamente invasiva, com ênfase no resultado radiológico. Métodos Estudo retrospectivo de 49 pacientes com 64 fraturas intra-articulares de calcâneo, submetidos a tratamento cirúrgico minimamente invasivo. As lesões foram tratadas com redução aberta por acesso mínimo lateral à articulação subtalar e fixação mínima. Foi realizado estudo radiográfico no pré- e no pós-operatório para aferição dos ângulos de Böhler e de Gissane. Resultados O ângulo de Böhler médio dos casos antes da cirurgia foi de 2,5º, apresentando aumento da média dos ângulos para 25,3º após o tratamento cirúrgico minimamente invasivo. O ângulo de Gissane médio dos casos antes da cirurgia foi de 136,3º, apresentando diminuição da média dos ângulos para 114,3º na análise após a cirurgia. Conclusão A técnica cirúrgica minimamente invasiva permite melhora dos parâmetros radiográficos (ângulos de Böhler e Gissane) nas fraturas intra-articulares de calcâneo, com sua adequada recuperação da forma anatômica.
