BACKGROUND: The natural history of untreated tarsal coalitions is largely unknown. It is thought atypical biomechanics of limited hindfoot motion may contribute to early degeneration and foot pain or dysfunction. Consequently, there is no data on long-term outcomes of nonoperatively managed asymptomatic tarsal coalitions. This study sought to define the frequency of radiographically apparent tarsal coalitions among a cross-section of a population not seeking care for foot symptoms. Ultimately, we aimed to observe the natural history of these coalitions by comparing multiple functional scores and radiographic foot osteoarthritis between participants with and without radiographic coalition to see if coalition presence is associated with worsened scores and or radiographic osteoarthritis. METHODS: Utilizing existing data from a community-based study, radiographs were reviewed for findings of calcaneonavicular (CN) and talocalcaneal (TC) coalitions. Patient and foot-specific outcome scores [patient-reported outcomes measurement information system (PROMIS), foot and ankle outcome score (FAOS)] and radiographic foot osteoarthritis scoring were compared between "Coalition present"(C) and "No Coalition" (NC) groups. RESULTS: Among 299 participants (592 feet) in this study (mean age: 72 y, 34% male, 41% Black), radiographic coalitions were found in 9.3% of feet, with 6.4% CN and 3.0% TC. PROMIS and FAOS were not significantly different between the NC and C groups. There was no statist...
