title: Medial Flatness of the Femoral Trochlea in the Nail Patella Syndrome.
abstract: The knee joint of an adult male with a nail patella syndrome was examined by standard X-rays and by computerised tomography. The dysplasia of the femoral trochlea has a specific sign which distinguish it from the "common" dysplasia of the recurrent patellar luxation type: a straight line flatness of the medial margin on the profile. This sign should be useful for the diagnosis of incomplete forms of the nail patella syndrome. Key words: nail patella syndrome, osteo-onycho-- dysplasia, knee dysplasia.
