Abstrakt: Background: Fixation of calcaneus through the sinus tarsi approach is increasingly popular due to the lower rate of wound complications. The use of postoperative CT provided a better evaluation tool than using plain radiography. Our objective of the present study is to evaluate the quality of fracture reductions by postoperative 3D CT scans after surgical intervention using the sinus tarsi approach and fixation with 3.5 cortical screws. Methods: Between January 2018 and April 2020, 86 consecutive patients with 92 closed displaced intra-articular calcaneal fractures underwent ORIF with 3.5 mm screws constructed via a minimally invasive sinus tarsi approach by a single foot and ankle surgeon. Results: The preoperative radiographic assessment found 36 joint depression type and 56 tongue type fractures according to the Essex–Lopresti classification. Preoperative CT assessment found 82 type II and 10 type III according to the Sander classification. Analysis of pre- and postoperative CT parameters showed that the height of the posterior facet, the length of the posterior facet, Gissane, and Bohler's angle were significantly improved. In addition, the means of posterior facet step-off in postoperative CT was 1.07, and 72% of posterior facet reductions were < 2 mm step-offs. Conclusion: With postoperative CT scan assessment, the treatment of displaced intra-articular calcaneal fracture with 3.5 mm screws via sinus tarsi approach has achieved good quality of reduction. Therefore, the screws-only technique is an option for treating calcaneal fracture with less soft tissue damage and implant cost. [ABSTRACT FROM AUTHOR]
