Limb loss, particularly in cases of partial amputation, and congenital limb malformations in dogs may affect mobility, biomechanics, and quality of life. In this context, customized orthopedic exoprostheses emerge as a promising therapeutic alternative, capable of partially restoring locomotor function, redistributing loads, and improving postural stability.
This study aimed to describe the development and clinical application of customized three-dimensional (3D) orthopedic exoprostheses in dogs with amputations and congenital malformations, using a case series design.
Six canine patients were included, three with involvement of thoracic limbs and three with involvement of pelvic limbs. Regarding etiology, four cases were associated with partial limb amputations and two with congenital malformations. All patients underwent clinical evaluation, anatomical measurements, and individualized prosthetic planning. The three-dimensional models were developed in software and printed in polylactic acid (PLA) using fused deposition modeling (FDM) technology. After hand-finishing, padding, and securing with compressive bandages, the devices were adapted to the patients’ residual limbs. Clinical monitoring was conducted, with emphasis on assessing functionality, skin integrity, gait stability, and response to rehabilitation.
The results demonstrated good acceptance by the animals, with no skin lesions, mechanical failures, or definitive refusal to use the devices. In all cases, improvements in mobility, stability, and quality of life were observed, with progressive adaptation and functional return to locomotion. Therefore, this study highlights the clinical potential of producing veterinary orthopedic exoprostheses using 3D printing, emphasizing its potential as an accessible, personalized, and functional strategy for the rehabilitation of dogs with missing or malformed limbs.
