Abstract Purpose The purpose of this study was to compare the post-operative radiographic and clinical outcomes of less invasive plate fixation versus screw fixation of displaced intra-articular calcaneus fractures (DIACFs) via sinus tarsi approach. Methods A total of 165 consecutive DIACFs that underwent open reduction internal fixation via sinus tarsi approach from 2013 to 2018 were reviewed at least a two year follow-up. The methods of fixation were divided into two groups: less invasive plate fixation versus screw fixation of calcaneus fracture (59 vs 106, respectively). The radiographic outcomes including pre- and postoperative Bohler’s and Gissane’s angles were evaluated. The post-operative function was evaluated using the American Orthopaedic Foot and Ankle Society (AOFAS) hindfoot score, the Olerud and Molander Scale and the Visual Analogue Scale (VAS). The complications, the rates of implant removal and cost were also compared. Results The average follow-up was 44.2 months in the plate groups and 47.9 months in the screw groups (P > 0.05). There was no significant difference in the Bohler’s angle and Gissane’s angle between the plate group and screw group during the preoperation and the last follow-up. There was no significant difference in the final AOFAS score, Olerud and Molander score and VAS score between the two groups (P > 0.05). The total incidence of complications was 6.7% in the plate group and 6.6% in the screw group (P > 0.05). The rates of implant removal and total cost during the hospitalization in the plate group were significantly higher compared with screws group (P < 0.05). Conclusion The less invasive plate fixation versus screw fixation of DIACFs via sinus tarsi approach contributed comparable quality of reduction, complications and post-operative functional outcomes. The less invasive plate technique was significantly higher in terms of implant costs and the rate of implant removal.
