Abstract
We reviewed 21 patients who were treated by postero-lateral fusion with the Diapason pedicular screw system for lumbar spinal disorders. Clinical and radiographic evaluation was carried out in these patients for a mean follow-up period of 7 months.
The rate of solid fusion 6 months after surgery was 85.7% in 14 patients. Displacement of the rod was encountered in one early case, but no screw breakage and no device-related neural or vascular injuries occured.
One significant advantage of this system is the relatively brief in comparison to other pedicular screw systems. Another advantage is that this titanium system possesses no risk for MR imaging and produces minimal artifacts on MRI and CT scans.
