Complications of the Pedicular Screw System Used for Spinal Disorders

Abstract

We reviewed 143 cases treated consecutively using the Pedicular Screw System for thoracic and lumbar spinal disorders. The purpose of the study was to clarify the rate of complications associated with the Padicular Screw System when used to treat spinal disoreds. The rate of infection and neurological deterioration were both 0.7%. Screw breakages were 5.6%, althaugh in traumatic lesions this increased to 13.3%. For these cases, we used the posterior bone graft technique alone.
We recommend the use of fluoroscopy for appropriate screw insertion and the use of anterior bone graft techniques for decreasing the incidence of screw breakages.
