Full Prosthesis or Carpal Orthosis? Which Aid to Choose After a Front Leg Amputation in Dogs

20/05/2025

If your dog has undergone a front limb amputation, it's essential to choose the right support device to maintain their mobility and overall health. As a manufacturer of animal orthoses and prosthetics, we prefer and recommend a carpal orthosis on the remaining front leg rather than a full prosthesis. This approach offers several advantages that contribute to faster adaptation and long-term well-being.

Benefits of a Carpal Orthosis

A carpal orthosis is a highly effective and gentle solution for dogs after the amputation of one of the front limbs. One of its biggest advantages is that dogs typically adapt to it much faster than to a full prosthesis. This is because the paw maintains natural contact with the ground, allowing for better spatial awareness and stability during movement. The orthosis does not restrict natural gait and doesn't feel foreign to the dog, making it easier for them to accept and use it.

Another major benefit is that the orthosis protects the carpal (wrist) joint from injury. After an amputation, the remaining front limb is under significantly increased strain—up to 60% of a dog’s body weight is typically carried by the front legs, and now that entire load is borne by just one leg. This greatly increases the risk of joint damage or a condition known as carpal collapse (dropped wrist). A carpal orthosis helps prevent this by mechanically supporting and stabilizing the joint during movement.

Equally important is the fact that a carpal orthosis contributes to maintaining healthy biomechanics in the long term. When the orthosis is properly designed and custom-made, it helps distribute weight more evenly and reduces the risk of unilateral overloading. This helps prevent pain, limping, and other complications that could negatively impact your dog's quality of life down the road.

When to Consider a Full Prosthesis

Although in the vast majority of cases we recommend a carpal orthosis on the remaining front leg after an amputation, there are situations where a full prosthesis may be the more appropriate option. A full prosthesis is usually considered when the dog is not a suitable candidate for a carpal orthosis—for example, if the amputation was performed high up at the shoulder level, or if the remaining front limb is unstable, deformed, or painful for any reason.

A full prosthesis is designed to provide additional support and help the dog compensate for the imbalance caused by the missing limb. While younger and more active dogs often prefer the freedom and natural contact of their paw with the ground, a prosthesis can be a better choice for older dogs who have already lived an active life and now suffer from conditions such as arthritis or joint stiffness. These dogs typically have less energy, are calmer, and appreciate the stable support that a full prosthesis can offer—especially while standing. For them, the solid structure of the prosthesis can provide relief and improve everyday comfort, both when moving and at rest.

However, it's important to keep in mind that adapting to a full prosthesis is usually more demanding and takes longer. The dog needs to learn how to use the prosthesis correctly, which may require patience, guided training, and in some cases, physical rehabilitation. Some animals may initially reject the prosthesis or perceive it as an obstacle. That's why we strongly recommend consulting a specialist before making a final decision. Based on the dog's health status, age, and physical condition, we can help determine the most suitable and supportive solution.

Our Recommendation

Based on our many years of experience in the field of orthotics and prosthetics for animals, we recommend choosing a carpal orthosis for the remaining limb in most cases after a front leg amputation. This device provides quick relief for the dog, protects the overburdened carpal joint, and does not restrict natural movement. The orthosis is well-tolerated even by active dogs who want to move confidently, comfortably, and without pain, even after such a significant procedure.

However, we understand that every case is unique – it depends on the dog's age, physical condition, health status, and individual temperament. In some cases, a full prosthesis may be a better option, or sometimes a combination of different aids, or a specially customized solution. Therefore, we always recommend consulting a professional before making a final decision on the choice of device.

If you, as a pet owner, are unsure which option is best for your dog, or if your attending veterinarian needs clarification, don't hesitate to contact us. We would be happy to advise you, assess the specific situation, and help find the solution that best suits your dog's needs – whether it's a carpal orthosis, a prosthesis, or another type of supportive aid. Our goal is for your dog to return to a high-quality life as quickly as possible, with minimal limitations and maximum comfort.
