STABLE SPINAL INSTRUMENTATION, A NEW GROUP OF INSTRUMENTS USED IN DEFORMITIES AND DISEASES OF THE COLUMNA VERTEBRALIS
Journal Title: Journal of Turkish Spinal Surgery - Year 1990, Vol 1, Issue 1
Abstract
The vertebral column is a mechanical structure which can move arount the frontal, sagittal and axial axes and on combinations of these axes. The supportive elements of this structure consist of the vertebra corpi, the facet joints, the intervertebral discs, the ligaments which attach the vertebra to each other and the muscles which surround the vertebral column. Any disturbance of any these structures can cause instability and deformity of the columns vertebralis. In order to be able to carry out daily vcrtcbralis comfortably, it is necessary to correct the vertebral deformity and the vertebral instability and to alleviate the resulting pain. Vertebra stabilization and correction is obtained by various methods. The oldest and most wide spread spinal instruments arc Harrington's instruments and they should be accepted as an important advance in spinal surgery (2). Although the application of Harrington instruments is quite easy the requirement of external fixation postoperatively has led orthopaedists to the search of new methods. Although Luque's segmental spinal instruments provide a stronger fixation and allow early mobilization postoperatively, their application has resulted with extreme correction loss. (3) The Cotrel-Dubousset method has added a new dimension to internal spinal instrumentation and it has been suggested that this method could effective to all dimensions of the deformity. The application has removed the requirement for an external support.
