© American Orthopaedic Foot & Ankle Society. Background: Hindfoot deformity has been described as a risk factor for poor hallux valgus (HV) surgery outcomes. However, there has been no study that demonstrates it. The purpose of this investigation was to evaluate the influence of hindfoot misalignment in HV surgery results. Methods: All patients operated on for HV during 2010 and 2011 at 3 university hospitals were included. The preoperative and 2-year postoperative radiologic data included the HV and the intermetatarsal (IM) angles, the naviculocuboid overlap (NC), the talonavicular coverage (TN) angle, the talus-first metatarsal (T-1MT) angle, as well as the calcaneal pitch (CP) angle. Additionally, the Short Form-36 questionnaire version 2.0 (SF-36) and the American Orthopaedic Foot & Ankle Society (AOFAS) score, satisfaction and recurrence were also analyzed. A total of 207 met the inclusion criteria. There were 26 patients (12.6%) who could not be assessed at the 2-year follow-up. Patients were allocated to a varus, normal, or a valgus hindfoot tertile using the values for the CP, NC, TN, and T-1MT angles. Results: No significant differences (P >.05) were found between the groups when the HV or IM angles, AOFAS, SF-36 Mental Composite Scale, SF-36 Physical Composite Scale, or satisfaction were compared. Similarly, no significant and strong correlations were observed (P >.05, ρ < 0.3) between any of the mentioned hindfoot measures and the outcomes scales. Conclusion: No influence of hindfoot misalignment on HV surgery outcomes was found in the present study in terms of correction, pain, function, satisfaction, or quality of life. Patients with hindfoot misalignment did not obtain worse outcomes in HV surgery. Level of Evidence: Level II, prognostic, comparative study.
