Three Cases of Aseptic Necrosis in Capitulum Humeri

Abstract

We report three cases of Panner's disease defined as avascular necrosis of the capitellum of the humerus.
Case 1; A boy aged eight complained of right elbow pain. The roetgenograms of the right elbow showed of irregularity of contour and a transparent zone in the capital epiphysis. Two months later, epiphysis became flat. Two years later, it changed completely.
Case 2; A boy aged eleven complained of right elbow pain. Roentgenograms of the right elbow showed irregularity of contour of the capital epiphysis. Ten months later, it remodeled alwost completely.
Case 3; A boy aged seven years was hospitalized for Perthes disease. The roentgenograms of the right elbow showed abnormal shade, irregularity of contour and a transparent zone of the capital epiphysis. Three months later, epiphysis became flat, but the contour smoothed.
It is usually easy to distinguish Panner's disease from osteochoudritis dissecans, but occasionally difficult. We define a part of the osteochoudritis dissecans as Panner's disease.
