Cervical interbody fusion cage HONOUR®

PATIENT POSITIONING Following adequate general anesthesia, the patient is placed in the supine position with the head in slight extension. The mandible is tilted out of the surgical field. The posterior cervical spine is supported to establish and maintain normal lordosis. EXPOSURE OF OPERATIVE LEVEL(S) Access the operative site and retract the tissues using preferred instruments. Retract the muscles, trachea, esophagus and carotid artery to clearly see the vertebral bodies and discs. Insert a marker into the disc(s) and confirm the correct operative level(s) using a lateral radiograph. DISCECTOMY Perform a complete discectomy using preferred surgical instruments. Pituitaries, curettes, and rongeurs may be used to remove the disc material and cartilage to expose the posterior longitudinal ligament and endplates. A high-speed burr may be used for removal of posterior osteophytes to achieve neural decompression. The posterior longitudinal ligament may be removed to access and remove any disc material that may be pressing on the neural elements. TRIALING AND ENDPLATE PREPARATION Final end-plate preparation is carried out using a rasp correlating to the trial spacer size (Fig 1.). A rasp may be used to decorticate the end plates with minimal bone removal and help ensure adequate end-plate preparation. 2mm recessed shaft stops may be used to prevent over-insertion of the rasp. Confirm the implant size and height by reinserting the trial after using the corresponding rasp.Once the appropriate height is identified, choose the corresponding Orb device.
