Panner disease is an osteochondrosis of the capitellum. It should be distinguished from osteochondritis dissecans of the elbow which also affects the capitellum.
Epidemiology
Panner disease is typically seen in children (5-10 years of age), although it is also seen in throwers due to repeated trauma. Panner disease occurs in a younger age group than osteochondritis dissecans which typically occurs in teenagers.
Radiographic features
On MRI typically the entire capitellum is affected and demonstrates low T1 signal and high T2 signal. In contrast to osteochondritis dissecans, Panner disease does not usually result in intra-articular loose bodies
Treatment and prognosis
It heals spontaneously with little if any residual deformity.
History and etymology
Named after Hans Jessen Panner (1871-1930), a Danish radiologist.
