If your dog is showing signs of pain or trouble moving their hip, it might be time to consider a surgery called Femoral Head Ostectomy (FHO). This surgery helps dogs with serious hip problems feel better and walk more easily. Knowing the signs your dog needs FHO can help you act early and improve their quality of life.

Signs Your Dog Might Need Femoral Head Ostectomy

Recognizing the signs early helps ensure your dog receives timely treatment for painful hip conditions that may require Femoral Head Ostectomy (FHO) surgery.

1. Difficulty Walking or Limping

Limping or difficulty walking is one of the most obvious signs your dog might need FHO surgery. When the hip joint is painful or damaged, your dog will try to avoid putting weight on the affected leg.

• Your dog may limp continuously or only after exercise.
• Favoring one leg over the other helps reduce pressure and pain in the hip.
• Difficulty walking may present as slow, hesitant steps or reluctance to move.

This limping indicates that the hip joint is not functioning properly due to pain, arthritis, fracture, or other damage. Persistent limping despite rest or medication is a strong sign that surgical intervention like FHO could be necessary.

2. Abnormal Gait or Favoring One Leg

An abnormal gait means your dog’s walking pattern changes because of discomfort or weakness. Dogs with hip problems may shift their weight unevenly, causing visible changes in how they move.

• Your dog may “swing” the affected leg or take shorter steps on that side.
• Uneven weight distribution may cause limping or skipping.
• The gait may look unbalanced or awkward, especially after activity.

These changes result from pain or instability in the hip joint. Abnormal gait often worsens over time and is a clear signal to consult your vet for possible surgery.

3. Loss of Weight-Bearing on the Affected Leg

Loss of weight-bearing means your dog refuses to put any weight on the painful leg. This is a severe sign of hip dysfunction and pain.

• Your dog may hold the leg completely off the ground while standing or walking.
• This can occur suddenly or develop gradually with worsening discomfort.
• Loss of weight-bearing leads to muscle weakness and further mobility issues.

When your dog stops using the leg due to pain, it often indicates advanced joint damage requiring surgical treatment such as FHO for pain relief and function restoration.

4. Persistent Hip Pain or Discomfort

Persistent hip pain affects your dog’s quality of life and is a common reason for FHO surgery.

• Your dog may show signs of discomfort such as whining or reluctance to move.
• Pain might be constant or worsen after activity.
• Hip pain reduces interest in walks, play, and normal activities.

Ongoing pain means conservative treatments are not controlling the condition, and surgery may be the best option to restore comfort and mobility.

5. Decreased Activity or Reluctance to Play

Changes in activity level are often one of the first signs owners notice when their dog is in pain.

• Your dog may avoid running, jumping, or climbing stairs.
• Reduced playfulness and slower movements indicate discomfort.
• Reluctance to exercise can lead to weight gain and muscle loss.

This behavior change shows your dog is trying to avoid pain, which may signal the need for surgical intervention like FHO.

6. Stiffness in the Hip Joint, Especially After Rest

Stiffness after rest or sleep is common in dogs with hip joint problems.

• Your dog may be slow to stand or walk after naps.
• The hip may feel tight or rigid, limiting movement temporarily.
• Stiffness often improves with gentle activity but returns after resting.

This stiffness indicates joint inflammation or damage, which may require surgery if it significantly impacts mobility.

7. Pain When the Hip Is Manipulated or Touched

During veterinary exams, pain responses when the hip is moved or touched can confirm joint problems.

• Vets check for tenderness by gently manipulating the hip joint.
• Pain during these tests often correlates with arthritis, fractures, or hip dysplasia.
• A painful response supports the need for further treatment or surgery.

This exam finding helps vets decide if FHO surgery is appropriate for your dog’s condition.

8. Limited Range of Motion in the Hip

A reduced ability to move the hip joint shows stiffness and pain.

• Your dog may struggle to fully extend or flex the leg.
• Limited motion causes difficulty in walking, running, or climbing.
• This restriction often worsens over time without treatment.

Limited range of motion is a key symptom indicating severe joint damage that may benefit from FHO surgery.

9. Muscle Loss or Atrophy in the Affected Leg

Muscle wasting happens when a dog stops using the painful leg regularly.

• You may notice the leg looks thinner or weaker compared to the other side.
• Muscle loss reduces joint support and slows recovery.
• Atrophy often signals chronic discomfort and long-term mobility issues.

Muscle loss is a serious sign that conservative care is no longer enough, and surgical options should be considered.

10. Chronic Lameness Not Improving Over Time

Lameness that does not improve with rest or treatment indicates the need for further evaluation.

• Persistent limping despite medication or physical therapy shows worsening hip disease.
• Chronic lameness reduces your dog’s activity and quality of life.
• This symptom often leads vets to recommend FHO surgery for pain relief.

Ignoring ongoing lameness can cause further joint damage and pain.

11. Joint Instability or Looseness Detected by the Vet

During exams, vets may find instability or looseness in the hip joint.

• The hip may feel unstable or shift abnormally during manipulation.
• Joint instability increases pain and risk of further injury.
• This finding supports surgical intervention to stabilize the joint and relieve pain.

Hip instability is often a clear reason to consider FHO surgery.

12. Reduced Quality of Life Due to Hip Issues

Chronic hip pain and mobility problems can greatly reduce your dog’s happiness.

• Dogs may become withdrawn, less playful, and reluctant to exercise.
• Pain and difficulty moving affect daily activities like walking or climbing stairs.
• Improving quality of life is a primary goal of FHO surgery.

If hip problems interfere with your dog’s enjoyment of life, surgery may provide relief and restore activity.

When to Consult Your Veterinarian About FHO Surgery

Early consultation with your veterinarian is essential if you notice signs of severe hip pain or mobility issues in your dog. Prompt veterinary evaluation helps diagnose the problem accurately and determine if Femoral Head Ostectomy (FHO) surgery is necessary.

• Importance of early consultation: Early vet visits can catch hip conditions before they worsen, improving treatment options and outcomes. Waiting too long may lead to increased pain, joint damage, and muscle loss.
• Diagnostic steps: Your vet will perform a physical exam to assess pain, joint stability, and range of motion. They will also recommend diagnostic imaging like X-rays to evaluate the hip joint’s condition.
• Treatment planning: Based on findings, the vet discusses conservative care options and, if needed, explains the benefits and risks of FHO surgery.
• Ongoing monitoring: Even if surgery isn’t immediately required, regular vet check-ups help track progression and adjust treatment plans.

Consulting your vet early ensures your dog receives timely care, reducing discomfort and helping maintain a good quality of life. Early diagnosis and intervention are key to successful management of hip problems.

How Veterinarians Diagnose the Need for FHO

Veterinarians use a combination of diagnostic tools and physical exams to determine if Femoral Head Ostectomy (FHO) surgery is the best option for your dog.

• Physical exams: The vet assesses your dog’s hip for pain, swelling, decreased range of motion, and instability. They watch how your dog walks and moves to identify signs of discomfort or limited mobility.
• X-rays: Radiographs provide a clear image of the hip joint, showing bone damage, arthritis, fractures, or deformities. X-rays are essential to confirm the severity of the problem and help plan treatment.
• Additional imaging: In some cases, vets may use advanced imaging such as CT scans or MRI to get detailed views of the joint and surrounding tissues.
• Evaluating symptoms: Vets also consider your dog’s history, including persistent limping, pain levels, and response to previous treatments.

Based on these findings, the vet decides if FHO surgery will relieve pain and improve your dog’s quality of life. Early diagnosis ensures timely intervention and better recovery outcomes. Working closely with your vet helps develop a tailored treatment plan that meets your dog’s specific needs.

What to Expect From Femoral Head Ostectomy Surgery

Femoral Head Ostectomy (FHO) surgery is a valuable procedure designed to relieve severe hip pain and improve mobility in dogs with damaged hip joints. By removing the femoral head and neck, FHO stops painful bone-on-bone contact, allowing your dog to move more comfortably.

• Surgery benefits: The main benefit is significant pain relief, which helps your dog regain use of the affected leg. FHO can improve quality of life, especially for dogs suffering from arthritis, fractures, or hip dysplasia.
• Surgical process: The surgery typically takes one to two hours under general anesthesia. Your dog will be closely monitored during and after the procedure to ensure safety.
• Recovery expectations: Recovery usually takes 6 to 12 weeks and involves rest, pain management, and physical therapy. Gradual weight-bearing and muscle strengthening are important for success.
• Owner’s role: Following your vet’s post-operative care instructions and attending follow-up visits are critical to a smooth recovery.

Most dogs adapt well to the changes and regain comfortable mobility, making FHO a highly effective solution for many painful hip conditions.

FAQs About Femoral Head Ostectomy (FHO) Surgery

How long does it take for a dog to recover from FHO surgery?

Recovery from FHO surgery typically takes 6 to 12 weeks. During this time, your dog needs restricted activity and physical therapy to rebuild muscle strength and improve joint mobility. Full recovery may continue over several months depending on the dog’s size, health, and rehabilitation efforts.

Is FHO surgery painful for dogs?

FHO surgery is performed under general anesthesia, so your dog won’t feel pain during the operation. After surgery, veterinarians prescribe pain medications to keep your dog comfortable while healing. Proper pain management is essential for recovery and helps your dog remain calm and active during rehabilitation.

What dogs are good candidates for FHO surgery?

Small to medium-sized dogs with severe hip pain caused by arthritis, fractures, hip dysplasia, or trauma are good candidates for FHO. Dogs who do not respond well to conservative treatments or other surgeries may also benefit. Your vet will evaluate your dog’s overall health and mobility to decide if FHO is suitable.

Can large dogs undergo FHO surgery?

Large dogs can have FHO surgery, but recovery can be more challenging due to their weight putting extra pressure on the new joint. For bigger dogs, vets often recommend alternatives like total hip replacement, which may provide better long-term mobility and comfort.

What are the risks of FHO surgery?

Risks include infection, muscle atrophy, decreased joint motion, and persistent limping. These risks are minimized by following post-operative care instructions closely, including medication, activity restriction, and physical therapy. Regular vet check-ups help identify and manage any complications early.

How does FHO surgery help improve mobility?

FHO surgery removes the damaged femoral head, eliminating painful bone-on-bone contact. The body forms a fibrous “false joint” that cushions the hip and allows pain-free movement. Combined with rehab, this improves your dog’s ability to walk, run, and enjoy daily activities comfortably.

‍

Understanding FHO Surgery

Femoral Head Ostectomy (FHO) is a surgical procedure where the head and neck of the thigh bone (femur) are removed. This surgery is done to relieve severe pain caused by hip problems like arthritis, fractures, or hip dysplasia.

FHO helps dogs by eliminating the painful bone-on-bone contact inside the hip joint. After surgery, the body forms a “false joint” made of fibrous tissue, which cushions the area and allows more comfortable movement. Although it’s not a normal joint, this new structure reduces pain and improves mobility.

This surgery is often recommended when other treatments like medication or physical therapy have not worked. It allows dogs to regain the use of their leg and live with less discomfort. FHO can be especially helpful for dogs with severe hip damage or those who cannot have more complex surgeries like total hip replacement.

How Veterinarians Diagnose the Need for FHO Surgery

Veterinarians use a combination of physical exams and diagnostic imaging to determine if Femoral Head Ostectomy (FHO) surgery is needed for your dog.

• Physical exam: The vet will assess your dog’s hip joint by checking for pain, swelling, decreased range of motion, and signs of lameness or instability. They will observe how your dog walks and moves to identify discomfort or limited mobility.
• Diagnostic imaging: X-rays are essential to see the condition of the hip joint, including bone damage, arthritis, fractures, or deformities. These images help confirm the diagnosis and guide treatment decisions.
• Signs and symptoms: Dogs showing severe hip pain, persistent limping, difficulty standing or walking, and poor response to medication or physical therapy are often evaluated for surgery.
• Additional tests: In some cases, advanced imaging like CT or MRI may be used for detailed views of the joint structures.

After evaluating these findings along with your dog’s age, size, and overall health, the vet decides if FHO surgery is the best option to relieve pain and improve mobility. Early diagnosis helps plan effective treatment and improve outcomes.

Medical Conditions That Indicate FHO Surgery

Femoral Head Ostectomy (FHO) surgery is often recommended for dogs suffering from specific medical conditions that cause severe hip pain and joint damage.

• Hip dysplasia and severe arthritis: Hip dysplasia is a genetic condition where the hip joint forms abnormally, leading to arthritis and chronic pain. When arthritis becomes severe, FHO can relieve pain by removing the damaged femoral head.
• Traumatic hip injuries: Fractures or dislocations of the femoral head or neck caused by accidents or trauma may require FHO if the bones cannot be repaired. This surgery helps restore comfort and function.
• Legg-Calve-Perthes disease: This condition causes the femoral head to deteriorate (necrosis) due to poor blood supply. FHO removes the damaged bone to eliminate pain and improve mobility.
• Degenerative joint disease in older dogs: Age-related joint wear and tear can cause chronic hip pain. When other treatments fail, FHO can improve quality of life by reducing discomfort and increasing mobility.

Your vet will assess these conditions through exams and imaging to determine if FHO is the best surgical option for your dog’s specific needs.

When Conservative Treatments Are Not Enough

Conservative treatments like medication, rest, and physical therapy are often the first steps in managing hip problems in dogs. However, these approaches may not always provide enough relief.

• Medication failure: Pain relievers and anti-inflammatory drugs can reduce discomfort temporarily, but if your dog continues to show pain or limping, medication alone may not be sufficient.
• Rest and activity modification: Limiting activity can help reduce stress on the hip joint, but persistent discomfort despite rest indicates the need for further intervention.
• Physical therapy limitations: While rehab exercises strengthen muscles and improve joint function, some dogs do not respond well enough to prevent ongoing pain or mobility issues.

When pain and limited mobility continue despite these treatments, it suggests the hip joint damage is severe. At this stage, Femoral Head Ostectomy (FHO) surgery may be recommended to relieve pain and improve quality of life.

Your vet will carefully evaluate your dog’s response to conservative care before suggesting surgery, ensuring that FHO is the best option for lasting relief and better mobility. Early surgical intervention can prevent further decline and discomfort.

Ideal Candidates for FHO Surgery

Femoral Head Ostectomy (FHO) surgery is best suited for certain groups of dogs based on their size, health, and response to other treatments.

• Small to medium-sized dogs: FHO works especially well for dogs under 50 pounds. Their lighter weight allows the “false joint” formed after surgery to support movement effectively, leading to better recovery and mobility.
• Dogs with poor response to previous treatments: If your dog has had medication, physical therapy, or other hip surgeries without sufficient pain relief or improvement, FHO may be the next best step to address ongoing discomfort.
• Dogs with significant reduction in quality of life: When hip pain severely limits your dog’s ability to walk, run, play, or enjoy daily activities, surgery can greatly improve comfort and function.

Vets consider factors like your dog’s age, overall health, activity level, and severity of joint damage when recommending FHO. While FHO may not be suitable for every dog, it offers excellent pain relief and improved mobility for many. Discussing your dog’s specific situation with your vet helps ensure the best treatment choice.

FHO Surgery as an Alternative to Total Hip Replacement

Total hip replacement (THR) is a highly effective surgery that replaces the entire hip joint with an artificial implant. However, THR may not always be feasible or affordable for every dog and owner.

• When THR is not feasible: Some dogs, especially smaller breeds or those with certain health issues, may not be good candidates for THR due to surgical complexity or recovery demands.
• Cost considerations: THR is usually more expensive than Femoral Head Ostectomy (FHO), making FHO a practical option for many owners seeking pain relief for their dogs.

FHO is a less invasive salvage procedure that removes only the damaged femoral head and neck, reducing pain and improving mobility without the need for artificial implants.

• Benefits of FHO: It generally has a shorter surgery time, fewer risks, and a good success rate, especially in smaller dogs. The formation of a “false joint” allows dogs to regain comfortable movement.

While THR can provide better long-term joint function for some, FHO remains a valuable, effective alternative for dogs needing pain relief with fewer surgical demands.

Expected Outcomes and Quality of Life Improvements

Femoral Head Ostectomy (FHO) surgery significantly improves pain and mobility in dogs suffering from severe hip problems. By removing the damaged femoral head and neck, FHO eliminates painful bone-on-bone contact, allowing dogs to move more comfortably.

• Pain relief: Most dogs experience a noticeable reduction in hip pain soon after surgery, which helps them regain willingness to walk, run, and play.
• Improved mobility: As muscles strengthen and the “false joint” forms, dogs regain better use of their leg, leading to a more active and happier life.
• Adaptation: Dogs naturally adjust to the new joint structure, often returning to normal activities with minimal discomfort.

Post-surgery rehabilitation plays a crucial role in maximizing these benefits. Physical therapy helps rebuild muscle strength, improve flexibility, and support joint stability. Controlled exercise and guided rehab reduce stiffness and prevent muscle loss, speeding recovery.

With proper care and rehab, most dogs enjoy a significant improvement in quality of life after FHO surgery, living comfortably and actively without the pain caused by their damaged hip joint.

Conclusion

Femoral Head Ostectomy (FHO) is a valuable surgical option for dogs suffering from severe hip pain caused by conditions like arthritis, fractures, or hip dysplasia. It relieves pain by removing the damaged femoral head, stopping painful bone-on-bone contact. This surgery improves mobility and helps dogs regain comfort, especially when conservative treatments have failed.

FHO is often recommended for small to medium-sized dogs or those that cannot undergo more complex surgeries like total hip replacement. The formation of a “false joint” allows dogs to move with less pain and better function.

Recovery and rehabilitation are important for the best results. If your dog shows signs of hip pain or difficulty moving, consulting your vet early is key. Personalized advice ensures the right treatment plan for your dog’s specific needs, helping them live a happier, more comfortable life.

FAQs

What dogs are the best candidates for FHO surgery?

Small to medium-sized dogs are the best candidates for FHO surgery because their lighter weight allows easier adaptation to the “false joint.” Dogs that have severe hip pain from arthritis, fractures, or hip dysplasia, and those who do not respond to conservative treatments, are also good candidates.

How long does recovery take after FHO surgery?

Recovery after FHO surgery usually takes 6 to 12 weeks. During this time, dogs need restricted activity and physical therapy to rebuild muscle strength and improve joint mobility. Full recovery can take several months depending on the dog’s size and health.

Can large dogs benefit from FHO surgery?

Large dogs can have FHO surgery, but recovery is often more challenging due to their weight. The “false joint” must support more load, which may affect mobility. Alternative treatments or total hip replacement may be better for larger dogs with severe hip issues.

Is FHO surgery painful for dogs?

FHO surgery is performed under general anesthesia, so dogs don’t feel pain during the operation. Post-surgery, pain is managed with medications prescribed by the vet to keep your dog comfortable during healing.

What are the risks of not treating severe hip problems?

Untreated severe hip problems can lead to chronic pain, arthritis, decreased mobility, muscle loss, and a poor quality of life. Over time, the condition worsens, causing more discomfort and difficulty with normal activities.

How does FHO compare to total hip replacement?

FHO removes the femoral head to stop pain, forming a “false joint,” while total hip replacement replaces the entire hip joint with an artificial implant. THR may offer better long-term function but is more complex and costly. FHO is less invasive and often preferred for smaller dogs or when THR isn’t feasible.

‍

What Is Femoral Head Ostectomy (FHO)?

Femoral Head Ostectomy (FHO) is a surgical procedure for dogs where the head of the thigh bone (femur) is removed. This surgery is done to relieve severe pain caused by hip problems. Without the femoral head, the painful bone-on-bone contact in the hip joint stops, which reduces discomfort.

FHO is usually performed when other treatments, like medication or therapy, have not helped. Common reasons for FHO include hip dysplasia, severe arthritis, fractures, or injury that damage the hip joint. The main goal of the surgery is to improve your dog’s comfort and quality of life by stopping the pain from a damaged hip.

After surgery, the body forms a “false joint” where the femoral head was removed. This new joint allows your dog to move more comfortably without the usual pain caused by the damaged bone. FHO can be very effective in helping dogs regain mobility.

Why Do Dogs Need FHO Surgery?

Femoral Head Ostectomy (FHO) surgery is recommended when dogs have severe hip problems that cause pain and limit movement. It is often chosen when other treatments like medication or physical therapy do not provide enough relief.

Common causes that lead to FHO surgery include:

• Hip dysplasia: A genetic condition where the hip joint develops abnormally, causing pain and arthritis.
• Severe arthritis: Wear and tear in the hip joint that causes inflammation, stiffness, and chronic pain.
• Trauma or injury: Damage from accidents, such as fractures or dislocations, that severely affect the hip joint.
• Fractures: Broken bones in the femoral head or neck that cannot be repaired easily.

FHO is usually recommended when these conditions cause persistent pain and reduce your dog’s quality of life. It is often chosen over hip replacement surgery for smaller dogs, or when the cost or complexity of other surgeries is not suitable.

The surgery helps relieve pain by removing the damaged bone, allowing your dog to regain mobility and live more comfortably. Your vet will decide if FHO is the best option based on your dog’s age, size, and condition severity.

How Does FHO Surgery Work?

Femoral Head Ostectomy (FHO) surgery involves removing the femoral head and neck—the round top part of the thigh bone that fits into the hip socket. By removing these damaged bone parts, the surgery eliminates painful bone-on-bone contact in the hip joint.

After surgery, the body naturally forms a “false joint” made of fibrous tissue and muscle in place of the removed bone. This false joint acts like a cushion, allowing the leg to move smoothly without bone grinding or pain. Although it’s not a normal joint, this fibrous tissue provides enough support for comfortable movement.

Inside the body, muscles and connective tissue around the hip adapt to stabilize the new joint area. Over weeks to months, scar tissue strengthens and improves flexibility, helping your dog regain use of the leg.

Because the bone is removed, the hip joint no longer causes pain from arthritis, fractures, or injury. The false joint helps your dog move more freely and reduces discomfort, improving quality of life. Proper post-surgery rehab is essential to build muscle and support this new joint.

Who Is a Good Candidate for FHO?

Femoral Head Ostectomy (FHO) is a good option for many dogs, especially those who suffer from severe hip pain that limits their mobility. Typically, smaller dogs weighing less than 50 pounds are ideal candidates because their lighter weight makes it easier for the false joint to support movement. However, dogs of any size or age may benefit from FHO depending on their condition.

Good candidates usually include dogs with:

• Severe hip arthritis causing chronic pain
• Hip dysplasia with joint damage
• Fractures or trauma to the femoral head or neck that cannot be repaired
• Poor response to medication or conservative treatments

FHO is often preferred over more complex surgeries like total hip replacement for younger dogs, smaller breeds, or when cost or health concerns make other options less suitable.

Your vet will evaluate your dog’s age, weight, activity level, and overall health to determine if FHO is the best solution. The goal is to relieve pain and improve mobility, giving your dog a better quality of life.

What to Expect During the Surgery

Femoral Head Ostectomy (FHO) surgery is performed under general anesthesia to ensure your dog is completely unconscious and pain-free. Before the procedure, your vet will conduct a full health check and blood tests to make sure your dog is fit for anesthesia.

During surgery, the vet makes an incision near the hip to access the joint. The femoral head and neck—the top part of the thigh bone—are carefully removed. The area is cleaned, and the muscles and tissues around the hip are sutured to help form the “false joint.” The skin is then closed with stitches or staples.

The surgery usually takes about one to two hours, depending on the dog’s size and condition. After surgery, your dog will be monitored closely as they wake up from anesthesia.

Immediate post-surgery care includes pain management, preventing infection, and limiting movement to protect the surgical site. Your vet will provide detailed instructions on medications and activity restrictions to help your dog heal safely and comfortably.

Recovery and Rehabilitation After FHO

Recovery after Femoral Head Ostectomy (FHO) requires patience and careful management. Physical therapy and gradual weight-bearing are key to helping your dog regain strength and mobility.

• Physical therapy: Helps rebuild muscles around the hip and improve joint movement. Without it, muscle loss and stiffness can slow recovery.
• Gradual weight-bearing: Start with short, gentle walks as your dog feels comfortable. Slowly increase activity following your vet’s guidance.
• Recovery timeline: Most dogs heal significantly within 6 to 12 weeks, but full improvement may take several months. Regular vet visits track progress.
• Owner’s role: Follow all activity restrictions and medication schedules. Assist with home exercises and provide a safe, calm environment.

Your care and attention during recovery greatly influence the outcome. By supporting your dog with controlled activity and rehab, you help ensure a smoother, faster recovery and improve their long-term quality of life.

Expected Outcomes and Benefits

Femoral Head Ostectomy (FHO) surgery offers significant benefits for dogs suffering from severe hip pain. The primary outcome is pain relief by removing the damaged femoral head, which stops the painful bone-on-bone contact in the hip joint.

• Pain relief: Most dogs experience a noticeable reduction in pain soon after surgery, allowing them to move more comfortably.
• Improved mobility: As the false joint forms and muscles strengthen, dogs regain better use of the leg, improving walking, running, and daily activities.
• Adaptation: Dogs naturally adjust to the new joint structure, often returning to an active and happy lifestyle.

The long-term prognosis for most dogs after FHO is excellent, especially when combined with proper rehabilitation and care. While the false joint is not a true hip replacement, it provides enough support for normal movement without pain. Small to medium-sized dogs usually recover faster and have better outcomes, but dogs of all sizes can benefit.

Overall, FHO improves quality of life by eliminating chronic pain and increasing mobility, allowing dogs to enjoy their favorite activities again.

Potential Risks and Complications

While Femoral Head Ostectomy (FHO) surgery is generally successful, there are potential risks and complications to be aware of during recovery.

• Muscle atrophy: Reduced use of the leg after surgery can lead to muscle loss around the hip. Without proper physical therapy, this can slow recovery and reduce strength.
• Reduced range of motion: Scar tissue and stiffness may limit how much your dog can move the leg if rehab is insufficient.
• Infection: Like any surgery, there is a risk of infection at the surgical site, which requires prompt veterinary treatment.
• Lameness or limping: Some dogs may continue to limp or show uneven weight-bearing after surgery, especially if healing is slow or if complications occur.
• Nerve or blood vessel injury: Though rare, surgery may affect nearby nerves or vessels, causing additional issues.

Follow-up care is essential to minimize these risks. Regular veterinary visits allow early detection and management of problems. Strict adherence to activity restrictions, medication schedules, and rehabilitation exercises supports healing and reduces complications. With careful monitoring and care, most dogs recover well and regain comfortable mobility.

Alternatives to FHO Surgery

Femoral Head Ostectomy (FHO) is one option for treating severe hip problems, but there are alternatives depending on your dog’s condition and needs.

• Conservative treatments: These include pain medications, anti-inflammatory drugs, physical therapy, weight management, and joint supplements. Conservative care is often tried first for mild to moderate cases or when surgery isn’t an option due to age or health. While it may help reduce pain, it usually does not fix severe joint damage.
• Total hip replacement (THR): This surgery replaces the entire hip joint with an artificial implant. THR is more complex and expensive but can provide better long-term function and mobility, especially for larger or active dogs. It is often preferred when joint damage is severe but the dog is healthy enough for major surgery.

Choosing between FHO and alternatives depends on factors like your dog’s size, age, activity level, and overall health. FHO may be better for smaller dogs or those who cannot undergo extensive surgery. THR can offer improved outcomes for some dogs but requires a longer recovery. Your vet will help determine the best option based on your dog’s specific situation.

How Veterinarians Diagnose the Need for FHO

Veterinarians use a combination of physical exams and diagnostic tools to determine if Femoral Head Ostectomy (FHO) surgery is necessary for your dog.

• Physical examination: The vet assesses your dog’s hip joint by checking for pain, swelling, range of motion, and signs of instability or lameness. They observe how your dog walks and moves to identify discomfort or limited mobility.
• X-rays: Radiographs help vets see the condition of the hip joint, including bone damage, arthritis, fractures, or deformities. X-rays are essential for confirming the diagnosis and planning treatment.
• Additional tests: In some cases, vets may use advanced imaging like CT scans or MRI to get a detailed view of the joint structures.

After evaluating the exam results and imaging, the vet considers your dog’s age, size, overall health, and lifestyle. They weigh the benefits and risks of surgery versus other treatments.

If pain and joint damage are severe, and conservative treatments haven’t helped, the vet may recommend FHO as the best option to relieve pain and improve mobility. Clear communication with your vet helps ensure the right decision for your dog’s care.

Conclusion

Femoral Head Ostectomy (FHO) is a valuable surgery that helps dogs suffering from severe hip pain caused by conditions like arthritis, fractures, or hip dysplasia. By removing the damaged femoral head, FHO stops painful bone-on-bone contact and allows the formation of a new “false joint.” This procedure significantly reduces pain and improves mobility, helping dogs regain comfort and quality of life.

Recovery requires patience, physical therapy, and owner support, but most dogs adapt well and return to active lives. FHO is often recommended for smaller dogs or when other treatments fail. If your dog shows signs of hip pain or mobility issues, consult your vet early. Understanding FHO can help you make informed decisions to give your dog the best care and a happier, pain-free future.

FAQs About Femoral Head Ostectomy (FHO) in Dogs

What is Femoral Head Ostectomy (FHO) surgery?
