Abstract
The interbody fusion cage technology provides a biomechanically sound and stable fixation of the functional spinal unit, a high probability of interbody fusion, and the removal of a proven, presumed or potentially pathologic intervertebral disc.
In this study, 40 patients with chronic low back pain [average duration of 24.2 months] which failed to respond to various conservative measures were assessed clinically and radiologically to detect the source of the back pain. 8 out of the 40 patients had previous failed back surgery for discogenic pain.
The clinical data were collected in a special she::t form covering all the important information and the radiological work up included:
Plain X-ray.
MRI.
Discogram including at least one control level. CT scan in some of the cases [18 patients]
Intraoperatively; the blood loss, operative time, levels of fusion and intraoperative complications were registered.
Anterior interbody fusion with SynCages was used in all 40 cases supplemented with transfacetal fixation with Magerl’s screws in 37 cases and transpedicular fixation with USS in 3 cases.
Bone graft was harvested from the vertebral body usmg
-;pccial bone harvesting tools.
