Legg-Calve Perthes (LCPD)

LCPD (also known as Avascular Necrosis) is a disorder of the hip joint occuring in both humans and dogs. It is most often seen in miniature and toy breed dogs between the ages of four months and one year.

LCPD is a result of interrupted blood supply to the femoral head resulting in avascular necrosis. This is followed by revascularization whereby the femoral head is subject to collapse or remodel, creating an irregular fit in the hip socket and leading to stiffness and pain. The results are similar to those experienced by larger breeds with Hip Dysplasia.

The degree of severity varies. No specific causes are known although it is believed to have a genetic mode of inheritance.
