RESUMO
OBJECTIVE: Achilles enthesitis and plantar fasciitis are the features of spondyloarthritis (SpA). Enthesophytes may indicate enthesitis, but their incidence is also high in elderly individuals and in athletes. This study aimed to clarify the incidences and risk factors of Achilles enthesophyte (AE) and plantar entesophye (PE) in SpA and trauma patients. METHOD: We retrospectively surveyed radiographs of the feet of SpA and trauma patients in our hospital. The SpA group included 17 patients (33 feet), and the trauma group included 33 patients (37 feet) who had undergone surgery between April 2013 and March 2014. RESULTS: The incidence of AEs was 63.6% (21 feet) in the SpA group and 54.1% (20 feet) in the trauma group (p = 0.45). The incidence of PEs was 48.9% (16 feet) in the SpA group and 16.2% (6 feet) in the trauma group. The SpA group had a higher prevalence of PEs than the trauma group (p < 0.01). The multivariate analysis showed that the risk factors for AEs and PEs were SpA and age. CONCLUSION: The risk factors for AEs and PEs were found to be advanced age and the presence of SpA.
