About Legg-Calve-Perthes Disease
Legg-Calve-Perthes Disease is a condition where the blood supply to the femoral head (ball of the hip joint) is disrupted, leading to avascular necrosis (bone death), collapse, and secondary osteoarthritis. It primarily affects young small-breed dogs between 4-12 months of age and is typically unilateral.
Category: Orthopedic
Severity: Moderate
Symptoms to Watch For in Your Bichon Frise
- Progressive hind limb lameness
- Pain on hip manipulation
- Muscle atrophy of affected leg
- Decreased range of motion
- Reluctance to bear weight
- Irritability when hip area is touched
Causes
The exact cause is unknown. Proposed mechanisms include vascular compromise (interruption of blood supply to the femoral head), hormonal influences, and genetic predisposition. Hereditary component suspected with possible autosomal recessive inheritance in some breeds.
Diagnosis
Radiographs showing femoral head irregularity, flattening, fragmentation, and eventual collapse. Early changes may be subtle. CT or MRI for early detection. Comparison with contralateral hip.
Treatment Options
Femoral head and neck ostectomy (FHO) is the standard surgical treatment with excellent outcomes in small dogs. Total hip replacement for larger dogs. Conservative management (rest, pain control) rarely successful long-term. Post-operative physical rehabilitation essential.
Prevention for Bichon Frise
Avoiding breeding of affected individuals. Genetic screening in predisposed breeds (Yorkshire Terrier, Miniature Pinscher, Poodle, West Highland White Terrier). No environmental prevention known.
Prognosis
Excellent with FHO surgery in small breeds - most dogs return to full, pain-free function. Without surgery, chronic pain and progressive osteoarthritis develop. Early surgical intervention provides best outcomes.
