RIGID AND DYNAMIC SPINAL FIXATION FOR TRAUMATIC AND DEGENERATIVE LESIONS

https://doi.org/10.14531/ss2009.3.8-13

Abstract

Objective. To estimate the efficacy of decompressive and decompressive-stabilizing operations for spine and spinal cord injury and degenerative dystrophic spine disease performed using rigid instrumented fixation or dynamic NiTi fixators.

Material and Methods. Decompressive and decompressive-stabilizing operations were performed in 212 patients with spinal injury and 256 patients with disc degeneration complicated by spinal cord and root compression. Spine stabilization with transpedicular systems was performed in 98 cases, and with dynamic fixators of NiTi with effects of memory, hyperelasticity, and self-regulated compression – in 89 cases.

Results. Instability of transpedicular fixation was observed in 6 (5.9 %) cases. The fracture of dynamic fixator in transition area between horizontal and loop parts occurred in 2 (2.4 %) patients in 7 years after surgery due to high physical load. The study of long-term results of dynamical fixator application for spine degeneration has not revealed radiological signs of overload and degeneration progression in the adjacent segments.

Conclusion. Results of operations performed with different fixation devices are comparable. Dynamical spinal fixation has certain advantages of lessening the intervention duration and decreasing in incidence of long-term complications.
