3D exoprosthesis in socket model for dog with amputed pelvic limb: case report

Area of Science:

• Veterinary Medicine
• Biomedical Engineering
• Additive Manufacturing

Background:

• Locomotor system disorders in dogs, including amputations, cause significant physical and emotional distress.
• Technological advancements offer solutions to enhance the quality of life for animals with mobility impairments.

Purpose of the Study:

• To describe the custom development and application of a 3D-printed exoprosthesis for a dog with a hind limb amputation.

Main Methods:

• A 3D exoprosthesis was custom-designed using measurements from the amputated limb.
• The prosthesis was fabricated using 3D printing with polylactic acid (PLA).
• The exoprosthesis was fitted and gradually introduced to the dog under supervision.

Main Results:

• The dog demonstrated immediate limb support and improved weight distribution upon prosthesis use.
• Within four weeks, the dog showed improved abilities in walking and running without complications.
• No injuries to the amputated stump were observed during the follow-up period.

Conclusions:

• 3D-printed exoprostheses represent a cost-effective method to mitigate locomotor deficits post-amputation in dogs.
• Additive manufacturing holds significant potential for veterinary applications, particularly for custom-fit assistive devices.
