Quality of life and complications in elderly patients after pronation rotation type III ankle fractures treated with a cast and early weight-bearing

Background: Early weight-bearing is becoming increasingly common because it can positively affect the quality of life of patients. Therefore, the efficacy and safety of this conservative treatment should be assessed for different types of ankle fractures. The goal of this study was to compare early weight-bearing and non-weight-bearing in terms of effectiveness and safety in patients with pronation rotation type III ankle fractures treated nonsurgically. Methods: A prospective multicenter cohort study was conducted over two years. Elderly patients with a nondisplaced pronation rotation type III ankle fracture were included. The main variables were the Barthel Index and SF-12 scores. The patients completed the questionnaires at six weeks, one year and two years. We also compared the complications associated with the two interventions. Results: 30 patients were included in the weight-bearing group, while 32 patients were included in the non-weight-bearing (WB) group. The mean ages were 82.6 ± 2.6 years and 83.1 ± 2.6 years, respectively. Quality of life, measured with the SF-12 scale, increased significantly in both the short and long term in the WB group (53.5 ± 5.8 points vs 65.2 ± 4.4 points at 6 weeks and 70.1 ± 4.2 points vs. 80.9 ± 3.7 points at 2 years; p<0.001). The WB group also showed a higher quality of life, as measured by the Barthel Index (54.5 ± 5.2 points vs. 64.3 ± 4.0 points at 6 weeks and 71.0 ± 4.3 points vs. 80.7 ± 3.4 points at 2 years; p<0.001). Conclusions: Elderly patients with pronation rotation type III fractures could benefit from an early weight-bearing protocol in terms of quality of life and functionality.
