[Osteo-onychodysplasia (nail-patella syndrome): a case-report (author's transl)]

A case of osteo-onychodysplasia (nail-patella syndrome) is reported. Features of this inherited condition include hypoplastic nails, hypoplastic to absent patellae, subluxation of the patellae, elbow dysplasia, and spurs in the posterior ileum (this last feature was absent in our patient). The nail hypoplasia is the most suggestive abnormality. Patients should be investigated for renal involvement which is a poor prognosis factor. In patients without renal involvement, prognosis is good.
