Legg Calvé Perthes disease in the dog

Area of Science:

• Veterinary Medicine
• Orthopedics
• Comparative Pathology

Background:

• Legg Calvé Perthes disease (LCPD) is a developmental abnormality affecting young, small breed dogs.
• The exact cause of LCPD is unknown, but its development mirrors that seen in humans.
• This condition involves aseptic osteonecrosis of the femoral head.

Purpose of the Study:

• To describe Legg Calvé Perthes disease in dogs.
• To highlight the similarities between canine and human LCPD.
• To establish the dog as a relevant model for studying aseptic osteonecrosis.

Main Methods:

• Diagnosis relies on physical examination and medical imaging.
• Treatment strategies, primarily surgical, are discussed.
• Comparative analysis of LCPD in dogs and humans.

Main Results:

• LCPD is a recognized condition in young, small breed dogs.
• Canine LCPD pathogenesis is highly similar to the human condition.
• Diagnosis and treatment protocols are established.

Conclusions:

• Legg Calvé Perthes disease in dogs offers valuable insights into human pathology.
• The canine model is useful for understanding aseptic osteonecrosis.
• Further research can leverage canine LCPD studies for comparative medicine.
