Complication Rates Are Similar Between Patients Aged <50 and >50 Years in Calcaneus Fractures Treated With the Sinus Tarsi Approach

Background: The sinus tarsi (ST) approach for calcaneus fractures has gained popularity in recent years with an increased interest in shifting to less invasive approaches for calcaneal fracture fixation allowing for adequate fixation if complications do not arise. Although the ST approach has gained acceptance as standard for calcaneus fracture fixation, the literature surrounding early complications rates based on age differences for this specific approach and pathology is lacking. The objective of this study was to determine if rates of complications based on age varied for patients undergoing open reduction and internal fixation (ORIF) of closed calcaneus fractures using the ST approach. Methods: A retrospective review of patients undergoing ORIF for closed calcaneus fractures from 2012 to 2020 was performed. Inclusion criteria were based on an age greater than 18 years, surgical management of a closed calcaneus fracture using a ST approach, requirement of a preoperative computed tomographic scan, and a minimum of 180 days’ follow-up. Patients were divided into 2 groups: those aged <50 years and those aged >50 years. Results: A total of 196 fractures were included with 114 fractures in the <50-year age group and 82 fractures in the >50-year age group. Mean age was 34.2 and 59.7 years in the younger and older groups, respectively. The older group had similar rates of wound dehiscence (1.2% vs 4.4%, P = .204), superficial surgical site infection (1.2% vs 2.6%, P = .490), deep infection (9.8% vs 7.9%, P = .648), and nonunion (4.9% vs 3.5%, P = .633) compared with the younger group. Rates of 30-day readmission, unplanned reoperation, and symptomatic hardware were not significantly different. Postoperative Bohler and Gissane angles were not significantly different between both groups. Conclusion: Older patients with intraarticular calcaneus fractures treated via the ST approach maintain complication rates similar to those in younger individuals. Level of Evidence: Level III, retrospective study.
