title: Köhler's disease of the tarsal navicular: long-term follow-up of 12 cases.
abstract: Twelve patients with Köhler's disease of the tarsal navicular were reviewed at follow-up averaging 33 years after diagnosis. All patients were asymptomatic. Neither alteration of the navicular shape nor osteoarthritis was observed radiographically. The type of treatment did not affect the time required for bone restoration, which took an average of 8 months. Weightbearing plaster casts for 3 months rendered the patients pain-free, whereas arch supports only decreased local pain, which lasted for an average of 7 months.
