USE OF DYNESYS INSTRUMENTATION IN LUMBAR SPINE DYNAMIC FIXATION FOR DEGENERATIVE DISEASE
Abstract
The experience in treatment of degenerative lumbar spine by the dynamic fixation with DYNESYS instrumentation (Sulzer Medica, Switzerland) was analyzed. From 2000 to 2003 the dynamic fixation was performed in 49 patients. Stabilization was combined with decompression in 44 patients, and pure stabilization was performed in 5 cases. The postoperative period was characterized by fast regression of pain syndrome, which was determined by segmental instability as well. Long-term results were followed up to 34 months. Pain and neurologic syndrome recurrences were not registered. Dynamic fixation, which preserved mobility in operated segments, created optimal functional conditions for patients' postoperative adaptation to regularity of living. Radiological examination did not reveal pedicle screw fracture or migration. Reduction of bone tissue density around screws in one case was asymptomatic. Cinematic analysis of the spine radiograms confirmed the maintenance of mobility in operated spinal segments but with less range of motion than before operation. Correction of the spine shape and orientation was not observed.
