title: Association of Achilles tendinopathy and plantar spurs.
abstract: Plantar spurs and Achilles tendinopathy are common causes of heel pain. In the authors' practice, it was anecdotally noted that patients with Achilles tendinopathy often presented with plantar spurs. Nonetheless, there is a shortage of studies investigating whether Achilles tendinopathy and plantar spurs exist concomitantly. A better understanding of the association between the 2 pathologies might help physicians recognize and treat both conditions, educate patients about Achilles tendinopathy and plantar spurs, and ultimately investigate possible underlying causes of both pathologies that could be addressed together. The authors examined the prevalence of plantar spurs in patients diagnosed with Achilles tendinopathy as well as demographic differences within the unilateral and bilateral Achilles tendinopathy populations. A total of 785 patient records were retrospectively reviewed. Mean patient age was 56.2±15.5 years (46.9% men and 53.1% women). Seventy-two (9.2%) patients were affected bilaterally by Achilles tendinopathy. Lateral radiographs were reviewed by an orthopedic surgeon to identify the presence of plantar spurs. A total of 329 (41.9%) patients with Achilles tendinopathy were found to have a concomitant plantar spur. Patients with unilateral Achilles tendinopathy and a plantar spur were more likely to be women (58.7% vs 49.8%, P=.020) and older (62.7 vs 51.7 years, P<.001). In the bilateral Achilles tendinopathy group, there were 46 (63.9%) patients with at least one foot presenting with a plantar spur. The study's findings suggest a significant association between Achilles tendinopathy and plantar spurs. Older women with Achilles tendinopathy are at greater risk of being affected by plantar spurs.
