Patented system New exclusive LDR Medical concept Graft and fusion The specifications of the roi implant aim at satisfying the requirements of lumbar intersomatic arthrodesis. Roi intersomatic cages were designed for degenerative lumbar spinal surgery. Using a posterior approach, the implant is introduced into the intervertebral space to enhance arthrodesis through bone fusion. The open geometry of this intersomatic cage explains it’s unique caracteristics which enhance the quality of bone graft. • A vast, single grafting area. • A vast, single end-plate freshening area. • Free bone to bone contact within a single fusion chamber.

Favour grafting by creating a fusion chamber A passion for innovation open radio transparent intersomatic implant a t e l

Radio-transparency and safety Transparency and consistency • The biocompatibility and mechanical qualities of P.E.E.K. are now widely recognised in intersomatic applications. • This material has an elasticity module close to that of bone, thus allowing the loading of the graft. 2 months post-op Bone and fusion chamber having priority, a radio transparent material was mandatory for fusion follow-up and control. There is also a biomechanical consistency between two vertebral segments, the fusion of which can be assessed and controlled over time by radio-transparency. Safety • ROI intersomatic cages...

A vast and single end-plate freshening area. • A meticulous freshening of vertebral The ROI concept favours grafting by creating a single FUSION CHAMBER. end-plates allows an optimal bone-to-bone graft, thus favouring high quality fusion. The lateral opening of the implants optimises the vertebral end-plates freshening area thus favouring a large,...

Optimised management • Sterile packaging of implants allows their immediate use at delivery, without any additional processing. The daily management of implants is therefore tremendously simplified. Sterile packaging • All ROI implants are delivered in sterile packages, under double blister pack, with sterilization stickers. Option implants are manufactured upon request (3 months delivery) Guarantee of mechanical properties • Sterile packaging is the guarantee of a new implant. It ensures the harmlessness and the perfect operational condition of the implant. Favour grafting by creating a fusion...
