Background: Managing displaced intra-articular calcaneus fractures is quite challenging, and there is ongoing controversy about the most effective treatment. The optimal approach for treating these fractures remains unclear. The purpose of this study was to determine how well the sinus tarsi technique fixed misplaced intra-articular calcaneus fractures. 
Methods: This prospective clinical study was carried out on twenty adult patients suffering from recent displaced unilateral intra-articular fractures of calcaneus admitted in Orthopedic department of Shebin El-Kom Teaching Hospital from September 2020 and august 2021 that were treated utilizing an open reduction and internal fixation technique that minimizes invasiveness to the sinus tarsi, employing a miniplate and cannulated screws for stabilization. All patients were evaluated pre-operatively through: Clinical evaluation and radiological evaluation. 
Results: Preoperative Bohler angle and American Orthopaedic Foot and Ankle Society (AOFAS) score showed a statistically substantial association while no significant correlation was founded between AOFAS score and (Age, Sex, preoperative Gissane angle, postoperative angle of Bohler, postoperative angle of Gissane). A statistically substantial association among Sanders type and (Age, preoperative Bohler angle) while no significant correlation was founded between Sanders type and (Sex, preoperative Gissane angle, postoperative Bohler angle, postoperative Gissane angle). 
Conclusions: The sinus tarsi technique is a minimally invasive method that efficiently treats intra-articular calcaneus fractures. The advantages of this approach for Sanders Type II fractures are higher than those for Type III fractures.
