Hypertrophic osteodystrophy in dogs

Area of Science:

• Veterinary Orthopedics
• Canine Pathology

Background:

• Hypertrophic osteodystrophy (HOD) is an uncommon orthopedic disease affecting young, growing dogs.
• The etiology of HOD remains unknown, with theories including viral infections, vaccinations, hereditary factors, and autoimmune disorders.

Purpose of the Study:

• To summarize the clinical presentation, diagnostic methods, treatment strategies, and prognosis for canine hypertrophic osteodystrophy.

Main Methods:

• Clinical sign assessment for suspicion of HOD.
• Radiographic confirmation using the characteristic "double physis" finding.
• Review of current treatment protocols and prognostic indicators.

Main Results:

• Affected dogs exhibit lameness, lethargy, fever, and limb swelling.
• Radiographs reveal a radiolucent line parallel to the physis, confirming HOD.
• Treatment success varies with severity, with mild to moderate cases having favorable prognoses.

Conclusions:

• Early diagnosis and supportive care are crucial for managing hypertrophic osteodystrophy in dogs.
• Prognosis is favorable for mild to moderate cases, but guarded for severely affected individuals.
• Further research into HOD etiology is warranted to improve preventative strategies.
