Spinal Devices

Inter-body cages

Conventional spinal fusion devices (cages) do not always fit a patient’s anatomy and require prepping of vertebral endplates to accommodate the device.  Once inserted, suboptimal fit of the device with those endplates can create pressure hotspots that can lead to subsidence of the device into the endplate – thereby obviating the purpose of the procedure and potentially leading to renewed pain and reoperation for the patient.  Patient-specific devices that fit well can overcome these deficiencies.

Vertebrectomy Devices

Certain procedures require the removal of one or more vertebrae and replacement with devices that provide stability and fixation while conforming to adjacent vertebral endplates.  Our patient-specific solutions have  demonstrated good initial stability, while significantly reducing operating theatre time for implantation.  The implications are reduced infection risk for the patient, reduced blood loss, and a reduction in operation costs.
