FHO surgery costs $1,500-$3,000. The blood supply to the femoral head (hip ball) is disrupted during growth, causing bone degeneration and collapse. Affects small and toy breed puppies at 4-12 months old. Surgery has excellent outcomes.

What Is Legg-Calve-Perthes Disease
Also called avascular necrosis of the femoral head. Blood supply to the hip ball is disrupted during growth, causing bone death and collapse. Hereditary origin, exact cause unknown. Typically affects one hip; both involved in 10-15% of cases. Almost exclusively small breeds under 20 pounds

Symptoms

What to Watch For
A hind leg limp that gets worse over weeks to months. Hip pain on manipulation. Thinner muscles in the affected leg. Reluctance to jump, climb stairs, or play. Chewing or licking at hip area. Symptoms typically appear at 4-12 months of age

Diagnosis

$200-$400
Orthopedic exam ($75-$150) shows hip pain on extension and rotation. X-rays ($150-$300) reveal characteristic femoral head changes - irregular shape, flattening, fragmentation. X-rays are usually definitive. Average $200-$400

Treatment

$1,500-$3,000
Femoral head ostectomy (FHO) is standard - the damaged femoral head is removed and scar tissue forms a false joint. FHO costs $1,500-$3,000. Small dogs recover very well. Total hip replacement ($4,000-$7,000) is rarely necessary. Average $1,500-$3,000

Total Cost

$1,700-$3,400
Diagnosis plus surgery and post-op physical therapy. A one-time expense with excellent long-term results. $1,700-$3,400 total.

Certain Breeds

Higher Risk
Yorkshire Terriers, Miniature Poodles, West Highland White Terriers, and Chihuahuas. Virtually all cases are in dogs under 20 pounds.

Recovery

6-8 Weeks
Physical therapy starts 1-2 weeks after surgery. Most dogs are weight-bearing within days. Full recovery to normal activity in 6-8 weeks.

Prevention
It can't be prevented since it's hereditary. Affected dogs should not be bred. Early diagnosis and surgery produce the best outcomes.

Insurance Traps

A hereditary orthopedic condition in puppies - timing and policy terms matter.

Coverage Basics

Coverage
Legg-Calve-Perthes is hereditary and orthopedic. Policies must cover both hereditary conditions and orthopedic procedures. Most comprehensive plans do, but check before you enroll.

The Puppy Timing Problem

Pre-existing
Symptoms appear at 4-12 months. Many policies have a 6-month orthopedic waiting period. If limping appears before the period ends, claims may be denied. Enroll your puppy at 8 weeks when possible.

Cost vs Deductible

Deductible
At $1,500-$3,000, FHO surgery exceeds most deductibles. With 80% reimbursement and a $250 deductible, insurance saves $1,000-$2,200 on this clear-cut surgical case.

One-Time vs Chronic

Chronic condition
Legg-Calve-Perthes is typically a one-time surgical fix with no ongoing treatment. Post-surgical physical therapy is usually covered as part of the claim.

Common Questions

Real answers about costs, treatment, and insurance coverage.

What are the first signs of Legg-Calve-Perthes?
A hind leg limp that gradually gets worse - your dog may favor the leg, hold it up, or be reluctant to play and jump. The limp worsens over weeks to months with visible muscle wasting. Most cases diagnosed between 4-12 months of age.
How much does Legg-Calve-Perthes surgery cost?
FHO surgery: $1,500-$3,000. Diagnosis: $200-$400. Post-op therapy: $200-$500. Total: $1,700-$3,400. Hip replacement ($4,000-$7,000) is rarely necessary for small breeds.
What is FHO surgery?
FHO removes the damaged femoral head. Scar tissue and muscle form a false joint that works for pain-free movement. Small dogs (under 20 lbs) recover very well thanks to their light weight. Most return to normal activity within 6-8 weeks.
Can Legg-Calve-Perthes heal without surgery?
Very rarely. Conservative management with pain meds, rest, and physical therapy is occasionally tried for mild cases, but the deteriorating femoral head continues causing pain. Most dogs need surgery. Waiting makes outcomes worse through muscle loss and joint damage.
How long does recovery from FHO take?
Most dogs bear weight within days. Physical therapy starts 1-2 weeks post-op. Controlled exercise increases gradually over 6-8 weeks with swimming and gentle walks. Full recovery takes 6-8 weeks with excellent long-term outcomes.
Which breeds get Legg-Calve-Perthes?
Almost exclusively small and toy breeds. Yorkshire Terriers most commonly, followed by Miniature Poodles, West Highland White Terriers, and Chihuahuas. Extremely rare in medium and large breeds. Any hind leg limp in a small-breed puppy warrants X-rays.
Can Legg-Calve-Perthes affect both hips?
Yes, but uncommon - about 10-15% of cases. Surgery may be done simultaneously or staged weeks apart. Bilateral cases cost more but achieve good outcomes with FHO. Always X-ray both hips even if symptoms appear on one side only.
Does pet insurance cover Legg-Calve-Perthes surgery?
Yes, if your policy covers hereditary conditions and you enrolled before symptoms appeared. The main risk: many policies have 6-month orthopedic waiting periods, and symptoms appear at 4-12 months. Enroll your small-breed puppy early. Coverage saves $1,000-$2,200 on surgery.

Then came the shock. August 2026, I'm sitting on a bench outside a veterinary clinic in Brno. After his first epileptic seizure. Alf, healthy until recently, has just been diagnosed with a tumor in his belly and one in his head. I look at my own realvetcost.com, and it's one of the three most common conditions in Boxers.

I don't want to see the prognosis, but it's clear. How did it end?
