The cause of an aseptic bone necrosis, localised on the femoral diaphysis of a patient aged 13, was vascular malformation, a so-called Hoyer-Grosser's glomangioma. The local insufficiency of the blood-supply, orginating from arteriovenous or lymphohaemangiomatous anomaly became manifest during the accelerated growth in puberty, in consequence of the increase of the requirements. It may be presumed that the necrosis in the given area, which healed in unobserved manner, occurred earlier. The intact bone structure in the environment allowed the reparation. In the course, the sequestration replacing the organization may have been attributed to overstrain, or to the non-axial loading, having an effect in the femur's longitudinal axis. Such loading, having an effect not in the femur's longitudinal axis, is an every day observation in the bicycling Netherlands.
