Cervios chronOS / Vertebral Spacer-CR chronOS

Interbody fusion procedures involve the use of bone grafts and bone replacement materials to encourage bony fusion. Studies have shown that the success rate of fusion depends on the intraoperative packing of the interbody fusion implant with the bone substitute. Therefore, the AO offers the Cervios/Vertebral Spacer CR as prefilled cages with chronOS to complement or even replace painful bone graft harvesting from the iliac crest.

ChronOS is a resorbable ceramic (-TCP) bone substitute which is fully synthetic and has an interconnective open porosity. In-vivo studies have demonstrated its osteoconductive behavior and later resorption within 32 weeks.

Cancellous Bone Impactor

Holder for Implants and Trial Implants

Instrument Set for Cervical Distractor
