Management of unstable thoracolumbar and lumbar spinal injuries using pedicular screw plate fixation.
Thoracolumbar and lumbar spinal injuries can be physically and mentally devastating to a patient. Most of the patients are young working males i.e. the productive population in our country. Many methods of spinal stabilization have been proposed and advocated. A prospective study of fifty cases of unstable thoracolumbar spinal fractures stabilized by the Steffee VSP System was carried out. Fall from a height (usually a tree) was the most common mode of injury. In addition to pedicular screw plate fixation, laminectomy was done in some case with neurological deficit followed by inter transverse process bone grafting. Most of the cases i.e. forty five were segmental fusions but multisegmental fusions were done in five cases.
All the cases showed neurological improvement or remained stationary. There was no neurological deterioration in any case. All but two cases showed spinal angulation correction the mean being 13.050. Mean sagittal index correction was 0.23. The surgical procedure, anatomy of the pedicle and biomechanics of pedicular screws was discussed along with some of the complications.
In our small and short series we have been gratified with the results. However, there is a need to operate more cases and follow up for a longer duration before coming to any categorical conclusion.
