Abstract

Background: Calcaneal fractures are the most common type of tarsal fractures. The sustentaculum tali (ST) offers anatomical stability in calcaneal fractures, and recently, ST screws have been widely used in their treatment. This study aimed to investigate the clinical efficacy and value of ST screw fixation via a modified sinus tarsi approach (MSTA) for treating displaced intraarticular calcaneal fractures (DIACFs). Methods: This study enrolled 64 patients (64 feet): 32 patients in the calcaneal locking plate combined with the ST screw group (CLP-STS Group) and 32 patients in the simple calcaneal locking plate internal fixation group (CLP Group). The minimum follow-up duration was 18 months. Ankle function was evaluated using VAS, AOFAS, and Short Form-36 scores. Imaging evaluation included the Böhler angle, Gissane angle, length, height, and width of the calcaneus, and the Böhler angle in both groups 1 year after surgery. Results: Functional evaluation revealed that postoperative AOFAS and VAS scores in the CLP-STS Group were significantly better than those in the CLP Group. After surgery, the Böhler angle, Gissane angle, and length, height, and width of the calcaneus were significantly corrected compared to the preoperative values; however, the difference in these indicators between the two groups was not significant. Nevertheless, at the 1-year postoperative follow-up, the calcaneal Böhler angle loss in the CLP-STS Group was significantly better than that in the CLP Group. Conclusion: Compared to simple calcaneal locking plate internal fixation, combining the plate with the additionally free ST screw can resolve the limited intraoperative exposure of MSTA, reduce postoperative foot pain in patients, and improve clinical efficacy.
