Case Discussion

Nail-patella syndrome (synonyms: Fong’s disease, Trauner-Rieger syndrome) is a rare autosomal dominant condition.

Clinically the key feature is absent/hypoplastic nails from birth.

Diagnostic radiographic findings include the following:

  • absent/hypoplastic patellae (with a tendency to recurrent dislocation)
  • hypoplasia of the radial head or capitellum (leading to subluxation/dislocation)
  • bilateral posterior iliac horns.
    • the bilateral posterior iliac horns are due to exostoses arising from the posterior aspect of the iliac bones are present in as many as 80% of patients; this finding is considered pathognomonic for the syndrome
