Meyer?s dysplasia is an alteration in the development of infant hips, frequently misdiagnosed,
characterized by irregularity and delay of ossification of the capital femoral
Clinical observation: three case histories, which diagnostic criteria are compatible with
Meyer?s syndrome, were located and initially diagnosed as Perthes disease or avascular
necrosis of the femoral head.
The patients were diagnosed because of pelvic oblicuity from birth. In their evolution, a
delay was observed in ossification of the femoral head and a nucleus fragmentation at age
2. The patients remained asymptomatic throughout their follow up and remained under observation
as the only treatment.
Discussion: controversy exists in distinguishing diagnosis between Meyer?s syndrome
and Perthes disease, where some authors point at different syndromes or different manifestations
of the same illness. Its importance takes root in distinguishing diagnosis between
Perthes disease and avascular necrosis after treating hip displasia to avoid unnecessary diagnostic
tests and treatment.
