- Reported surgical treatments for canine spinal malformations use implants to stabilise the spine. Established techniques have a relatively high incidence of complications, present technical difficulties or require a thoracotomy. A new design and manufacture process was requested by collaborating consultants. They required: a) Titanium implants so that they could avoid the potential problems inherent by using Polymethyl Methacrylate and perform a post-op Magnetic Resonance Imaging (MRI); b) The implants to be easily removable in case of revision surgery or an infection. c) A personalised drill guide to accurately place optimised pedicle screws. d) A reduction in surgery time. The design methodology incorporated a virtual planning Computer-Aided Design platform ensuring the trajectory pathway of each screw which gains sufficient bone purchase and avoids critical anatomical landmarks (e.g. spinal cord, foraminae and intrathoracic vessels). The surgical drilling guide with a novel peg and clamp design was additively manufactured in a medical grade biocompatible polymer to securely fixed the personalised drill guide to the spine, so it is rigid, enabling the titanium screws to be correctly orientated into the vertebral body. Anatomically correct titanium implants were manufactured a GE Additive Arcam EBM Q10plus in titanium Ti6A14V ELI (certified to the USP Class VI standard for biocompatibility). Research Insights: New surgical technique with improved anatomical accuracy of implant and osseointegration which is also now used as part of surgical treatment for subarachnoid diverticulae, to cover the laminectomy defect and stabilise the adjacent vertebrae. Improved pre-operative planning and reduced theatre time due to novel peg and clamp design for drill guide system. Client Dissemination: Veterinary adoption by Willows veterinary centre and referral service (2018) and Langford small animal veterinary hospital (2018). Industrial dissemination: Research presented in collaboration with General Electric at GE Additive booth (Hall 3.0, Booth D30) at Formnext, Frankfurt, November 14, 2018.
