[Osteochondritis ischiopubica--van Neck-Odelberg disease in the differential diagnosis of coxalgia]. / Osteochondrosis ischiopubica--morbus van Neck-Odelberg v diferenciálnej diagnostike koxalgií.

The authors describe five cases from out-patient practice, whose pains were localized into lumbar joint due to the damage of ischiopubic joint in children at the age of five to twelve years. Aseptic necrosis of ischiopubic localization has been described in available literature as morbus van Neck-Odelberg. A description of clinical and X-ray picture is described, in the first case being typical in all stages of X-ray symptoms. Some symptoms described in literature were or were not identical. It proved to be impossible to demonstrate the influence of an injury as a trigger factor, but limitation in the homolateral lumbar joint (abduction or adduction component) as well as spontaneous tension of adductors were regularly observed. Flexion and extension were not limited with the exception of the fifth patient. A general picture of the described disease may be established on the basis of clinical and, particularly, X-ray picture.
