The final injury Dr. Harris discussed was Iselin’s disease, which is a secondary center of ossification at the site of insertion of the peroneal tendon at the base of the 5th metatarsal. Pain in the region is exacerbated by excessive lateral ankle movement. “On an x-ray, this looks like a small crescent of bone growing that hasn’t completely fused yet,” she said. “It’s often misread as a fracture, but it’s normal development.” Treatment consists of activity modification, icing, and NSAIDs as needed, and an ankle brace to provide lateral ankle support. She described Iselin’s as “harmless and short lived, from 6-10 months at the most.”
Dr. Harris reported having no financial disclosures.
