FHO (Femoral Head Ostectomy) is a surgical procedure that removes the ball (femoral head) of the hip joint, allowing the body to form a "false joint" from scar tissue. It's one of the most affordable orthopedic surgeries and is commonly used for dogs with hip dysplasia, femoral head fractures, or severe hip arthritis.
The average cost of FHO surgery is $2,000, with most owners paying between $1,000 and $3,000 per hip. It's significantly cheaper than total hip replacement ($3,500–$7,000) because it doesn't use an implant.
How Much Does FHO Surgery Cost?
| Cost Component | Price Range |
|---|---|
| Pre-surgical exam & X-rays | $150–$350 |
| Pre-surgical blood work | $80–$200 |
| FHO surgery | $1,000–$3,000 |
| Take-home pain medication | $30–$80 |
| Physical rehabilitation (critical for FHO) | $50–$100/session (6–12 sessions) |
| Total Cost | $1,400–$4,400 |
Cost by Clinic Type
| Clinic Type | Price Range | Notes |
|---|---|---|
| General practice vet | $1,000–$2,500 | Most GPs can perform FHO — no specialist needed |
| Board-certified surgeon | $1,500–$3,000 | More experience, higher cost |
| Teaching hospital | $800–$1,800 | Lowest cost, supervised by specialists |
| Low-cost clinic | $700–$1,500 | Some offer FHO at reduced rates |
Why Is FHO So Much Cheaper Than Total Hip Replacement?
FHO costs about half as much as total hip replacement because:
- •No implant: FHO removes the femoral head and lets scar tissue form a false joint. THR uses a titanium implant ($400–$800 wholesale cost).
- •No specialist required: General practice vets can perform FHO. THR requires a board-certified surgeon with specialized training.
- •Shorter surgery: FHO takes 45–90 minutes vs. 2–3 hours for THR.
- •Same-day discharge: Most FHO patients go home the same day. THR requires 1–3 nights of hospitalization.
- •Simpler equipment: FHO requires a bone saw and basic surgical tools. THR requires precision implant instruments.
FHO vs. Total Hip Replacement
| Factor | FHO | Total Hip Replacement |
|---|---|---|
| Cost | $1,000–$3,000 | $3,500–$7,000 |
| Best for | Small-medium dogs (<50 lbs), cats | All sizes (20+ lbs), active dogs |
| Result | False joint from scar tissue | Artificial joint (titanium) |
| Pain relief | Excellent — removes bone-on-bone contact | Excellent — new joint surface |
| Range of motion | Slightly reduced | Near-normal |
| Recovery | 4–8 weeks (needs active rehab) | 8–12 weeks (strict rest) |
| Long-term outcome | Good — pain-free, slight gait change | Excellent — normal function |
FHO Recovery — Why Active Rehab Is Critical
Unlike most surgeries where rest is the priority, FHO recovery requires active movement to form a good false joint. Too much rest can actually lead to poor outcomes.
Physical rehabilitation is essential for FHO: Without active movement, the scar tissue may not form properly, leading to a less functional false joint. Expect 6–12 rehab sessions at $50–$100 each.
- •Day 1–3: Pain management. Short, slow leash walks (5 min, 3–4x/day) to encourage movement.
- •Week 1–2: Increase leash walks to 10–15 min. Gentle range-of-motion exercises. Cold packs after activity.
- •Week 3–4: Longer walks (15–20 min). Begin swimming if available (excellent for FHO recovery).
- •Week 5–8: Return to normal activity. The false joint should be well-formed by now.
Frequently Asked Questions
How much does FHO surgery cost for a dog?
FHO surgery costs $1,000 to $3,000 per hip, with an average of $2,000. Total cost including diagnostics, medications, and physical rehabilitation is $1,400–$4,400. FHO is about half the cost of total hip replacement ($3,500–$7,000).
Is FHO a good option for my dog?
FHO is an excellent option for small to medium dogs (under 50 lbs) with hip dysplasia, hip fractures, or severe arthritis. It's also good for older dogs who may not tolerate the longer surgery required for total hip replacement. For large or highly active dogs, total hip replacement may provide better long-term function.
Does pet insurance cover FHO surgery?
Yes, most pet insurance covers FHO surgery if the underlying condition (hip dysplasia, fracture) wasn't pre-existing. Reimbursement is typically 70–90% after your deductible.
How long does FHO recovery take?
FHO recovery takes 4–8 weeks — faster than total hip replacement (8–12 weeks). However, FHO requires active movement and physical rehabilitation to form a proper false joint. Too much rest is actually counterproductive with FHO.
Can FHO be done on both hips at the same time?
Yes, bilateral FHO can be performed in one surgery, especially for small dogs and cats. This saves on anesthesia and hospitalization costs. However, recovery is more challenging since the dog has two healing hips. Bilateral FHO costs $2,000–$5,000 total.
