Total Elbow Replacement in Dogs: A Complete Guide

Since the seventies, joint replacement surgery has been successfully performed on dogs, improving quality of life for those with debilitating joint conditions. More recently, total elbow replacement (TER) has become an option for canine patients suffering from severe elbow osteoarthritis and other elbow disorders where other treatments have failed. If your dog suffers from elbow osteoarthritis, dysplasia, or chronic injuries, this guide will explain in detail the procedure, candidate criteria, recovery, risks, and ongoing care to help you make an informed decision with your vet.

What is Total Elbow Replacement and How Does It Work?

Total elbow replacement is an advanced surgical procedure where the damaged elbow joint surfaces—the humerus, radius, and ulna—are removed and replaced with artificial components. These implants, typically made from cobalt chrome and a high-grade polyethylene plastic, are designed to replicate the natural joint's anatomy and function.

Custom implants are often tailored to individual dogs based on detailed imaging such as CT scans, ensuring a precise fit and better outcomes. The implants are secured using bone cement, and the goal is to relieve pain from osteoarthritis and restore as much joint mobility as possible.

This surgery is considerably more complex than hip replacement because the elbow consists of three joint surfaces and requires precise restoration of biomechanics to maintain natural movement.

When and Why is Total Elbow Replacement Recommended for Dogs?

Veterinary specialists may recommend TER for dogs experiencing persistent elbow pain and lameness that do not respond to medications or more conservative surgeries. Common indications include:

• Severe elbow osteoarthritis causing constant pain and lameness
• Chronic elbow luxation or instability
• Fractures that have failed to heal properly

Before surgery, it is critical that infections or neurological conditions affecting the limb are ruled out. TER is a salvage procedure suited only for specific cases where pain severely compromises quality of life.

The Surgery: What to Expect

The total elbow replacement procedure requires experienced orthopaedic surgeons and a referral to specialised centres. Surgery involves:

1. Preoperative assessment: Health screening and imaging to assess elbow damage and overall fitness for surgery.
2. Removal of damaged joint surfaces: The diseased cartilage and bone of the humerus, ulna, and radius are removed carefully.
3. Implant placement: Prosthetic components are inserted and fixed with bone cement, replicating joint surfaces.
4. Closure: Soft tissues and skin are sutured after ensuring implant stability.

Surgical approaches vary; recently, lateral approaches have become more common, enabling effective implant placement with fewer complications. Surgery duration is longer than hip replacements due to complexity.

Recovery and Long-term Care

Postoperative recovery typically spans 8 to 12 weeks, during which your dog will gradually regain mobility. Initial improvements in comfort and weight-bearing are expected within weeks, but significant positive changes can take up to six months.

You should anticipate some persistent stiffness or slight lameness, not indicative of pain but a result of altered joint mechanics. Rehabilitation and controlled exercise tailored by your veterinary team can aid the recovery process and improve function.

Long-term care includes:

• Regular veterinary check-ups to monitor implant and joint health.
• Weight management to reduce elbow stress.
• Providing appropriate joint supplements or medications as recommended.
• Avoiding high-impact activities that may jeopardise the implant.

Risks and Potential Complications

As with any major surgery, there are risks associated with TER, including:

• Surgical site infection
• Implant loosening or failure
• Persistent lameness or pain
• Nerve injury or decreased limb function

Reported complication rates are around 15% within the first year post-surgery. In some cases where complications cannot be managed, alternative procedures such as elbow arthrodesis (joint fusion) may be required. While fusion eliminates pain, it limits mobility and alters gait.

Is Total Elbow Replacement Suitable for Your Dog?

Determining if your dog is a candidate involves thorough veterinary evaluation. Factors include age, overall health, presence of infections or neurological problems, and the extent of elbow damage.

If you suspect your dog could benefit from TER, discuss with your vet or a specialist orthopaedic surgeon about:

• Diagnostic tests to confirm suitability
• Expected outcomes and realistic goals
• Costs including surgery, aftercare, and rehabilitation
• Pet insurance options and coverage details

Responsible ownership means considering all alternatives and ensuring your dog’s welfare through every step.

Summary

Total elbow replacement in dogs has revolutionised treatment options for severe elbow joint disease when pain management and other surgeries are insufficient. It offers hope for better quality of life and reduced suffering with expert surgical care and committed recovery.

While expensive and complex, this procedure can be life-changing for dogs burdened with chronic elbow pain, and early discussions with your vet will help guide the best course for your pet.
