Patient-reported functional outcomes and health-related quality of life following fractures of the talus

Abstract

Introduction The primary aim of this study was to investigate patient-reported outcomes following talar fractures. Secondary aims were to investigate health-related quality of life and to determine whether it is influenced by functional outcome. Materials and methods This retrospective study identified 56 talar fractures over eight years. Patients were contacted by post and the Olerud and Molander score (OMS), Manchester–Oxford Foot and Ankle scores (MOXFQ) and Euroqol-5D-3L collected. Results The mean age was 35.2 years (range 13–78 years). There were four cases (7.1%) of avascular necrosis and one (1.8%) non-union occurred. Data from patient-reported outcome measures were available for 42 patients (75.0%) with a median follow-up of 67.1 months (range 23.2–111.8 months). Mean OMS was 60.0 (standard deviation ± 29.51) and median MOXFQ was 30.33 (interquartile range 47.13). Median Euroqol-5D-3L index was 0.74 (interquartile range 0.213) and median Euroqol-5D-3L visual analogue score was 80 (interquartile range 21). Older age, open fractures, multiple injuries and subsequent avascular necrosis were associated with worse patient-reported outcomes (P < 0.05), with older age, avascular necrosis and open fractures found to be independent predictors of poor OMS, and avascular necrosis and open fractures independently predicting MOXFQ score on regression analysis (P < 0.05). Poor self-reported function, measured by OMS and MOXFQ, correlated with worse health-related quality of life as measured by the Euroqol-5D-3L index (OMS: r = 0.764, P < 0.001; MOXFQ: r = 0.824, P < 0.001) and visual analogue score (OMS: r = 0.450, P = 0.003; MOXFQ: r=0.559, P < 0.001). Conclusions Older age, avascular necrosis and open fractures predict poorer functional outcomes following talar fractures. Patients with worse limb-specific functional outcomes are more likely to have a worse perception of health-related quality of life.
