Many implants and fixation devices used for animals were originally designed for use in humans, meaning that they often do not cater well with animal animal morphology.
3DMorphic has developed patient specific interbody devices for dogs. These are 3D printed in biocompatible Titanium alloy.
These devices have been used successfully to treat disc associated wobbler’s disease in large breed dogs. The use of these devices is published in the Peer Reviewed Journal ‘Veterinary and Comparative Orthopaedics and Traumatology’ (News & Media page).
The interbody devices are often used in conjunction with a ventral plate. The left hand image shows a CT slice of the construct immediately after the procedure.
6 Months after the operation (right hand image) the instrumented level shows a good fusion between the adjacent vertebral bodies. Fusion aims to stabilise the problematic level and decompress the affected neurological structures (spinal cord and exiting nerve roots).
Clinical results from these procedures have been good, with patients recovering well with improvements to their gait.
Implants and fixation devices developed for humans rarely fit animals. In addition, between different breeds of the same animal there can be substantial differences in morphology, again leading to poor fitting devices. This can lead to lengthy procedures with uncertain clinical outcomes, and can make many procedures unviable. 3DPlato has successfully demonstrated its capability to take existing digital device designs and adjust their shape– even radically – so that they fit animal anatomy. Our capability extends beyond spinal and internal fixation for limbs.Shown above is a generic inter veretebral body cage (left), the same cage adjusted to fit the inter vertebral body space of a dog (middle) and the intra operative x-ray of the implanted device.
