A Case Report of Panner's Disease

Panner's disease is defined as avascular necrosis of the humeral capitellum and was first reported by Panner in 1927. It usually occurs in boys younger than 10 years of age. Residual deformity and loose bodies are not usually seen.Osteochondritis dissecans, which sometimes results in residual deformity and loose bodies, need to be distinguished from Panner's disease.We experienced an eight-year-old boy with Panner's disease who was successfully treated by immobilization for 20 weeks. Radiograph and MRI showed satisfactory revascularization of epiphysis of the humeral capitellum. Prolonged immobilization may enhance the rapid revascularization of the humeral capital epiphysis.
