종골 관절내 골절에서 최소 침습적 내고정술의 결과

Abstract

Purpose: To evaluated the radiologic and the clinical results of minimally invasive technique in the management of Sanders type III, joint depressive type calcaneal fracture. Materials and Methods: Between July 2011 and September 2019, we studied 29 cases undergoing treatment with minimally invasive technique with sinus tarsi approach for Sanders III joint depressive intra-articular calcaneal fracture and were followed up for more than 1 year. We evaluated the radiologic result by assessing the radiologic parameters (Böhler angle, Gissane angle, calcaneal length, calcaneal height, calcaneal width) and clinical outcomes (AOFAS ankle-hindfoot score) and investigated the complications as well. Results: Radiological results improved from 2.5° to 18.6° in the Böhler angle after the operation and from 132.4° to 119.1° in the Gissane angle. Satisfactory results were obtained in clinical assessment with average AOFAS score of 79.5. We experienced 13 cases of posttraumatic arthritis, 1 case of subtalar arthrodesis and no case of infection. Conclusion: Minimally invasive technique for sanders type III joint depressive calcaneal fracture show relatively satisfactory radiologic and clinical results. Open reduction and internal fixation through sinus tarsi approach reduces complications including wound problems and is capable of satisfactory results and maintenance. so it may be an alternative to extensile lateral approach in Sanders III, joint depression type calcaneal fx.
