UNASSIGNED: The study aims to describe a three-dimensional printed (3DP) posterior fixation implant used for @entity6350 fusion in a 65-year-old female. Spinal fusion remains a common intervention for a range of spinal pathologies including @entity179 when conservative methods are unsuccessful. However, fusion devices are not always entirely efficacious in providing the desired fixation, and surgeons rely on 'off the shelf' implants which may not provide an anatomical fit to address the particular pathology. 3DP refers to a process where three-dimensional objects are created through successive layering of material, so called 'additive manufacturing'. Although this technology enables accurate fabrication of @entity1 -specific orthopaedic and spinal implants, literature on its utilization in this regard is rare. A 65-year-old female, with severe facet @entity2720 at the @entity6350 level, osteophyte formation and impingement of the exiting C2 nerve root underwent a @entity6350 posterior fusion and rhizolysis of the C2 nerve roots. A custom posterior fixation implant was designed and on-laid over the C2 spinous process and lamina, with screw holes made to a depth and angulation that was pre-calculated based on the preoperative CT based 3D modelling. The @entity1 had an uneventful recovery and reported a significant reduction in @entity9 and @entity158 and 2-month follow-up. We report the first case of a customized 3DP spinal prosthesis for posterior @entity6350 fusion. The implant added significant value reducing the overall time of the procedure, and safety with a reduced risk of neurovascular compromise.
