IntroductionSubtalar arthrodesis is a common salvage operation for posttraumatic subtalar arthritis, a condition frequently seen in patients who suffered major trauma. Functional outcomes in trauma patients may be influenced by concomitant injuries and the severity of the initial trauma. The aim of this study was to evaluate quality of life and functional outcomes of subtalar arthrodesis for posttraumatic arthritis in patients with severe or complex foot injuries.Materials and methodsThis is a retrospective single center study with prospective follow-up. Patients who underwent subtalar arthrodesis for posttraumatic arthritis between 2000 and 2016 were included and invited to complete a Maryland Foot Score (MFS), a EuroQol five-dimensional (EQ-5D™) and Visual Analog Scale (EQ-VAS™) questionnaire, and four additional questions.ResultsForty patients were included in the study, functional outcome scores were available for 30 patients (response rate 75%). Additional surgery of the fused foot was performed in 29 patients and 15 suffered multiple lower extremity injuries. Six patients were polytraumatized. Ninety percent of all patients would recommend the procedure to others, walking abilities improved in 69% and less pain was experienced in 76%. Median MFS score was 61 (IQR 53–72). Quality of life was significantly lower when compared to a reference population (p <0.001).ConclusionSatisfaction was high, as 90% of all patients would recommend subtalar fusion to others, even though the relatively poor outcome measures would suggest differently. Existing functional outcomes measures were influenced by concomitant injuries and additional procedures. This demands development of instruments suitable for severely injured patients with multiple or complex injuries.
