The Oswestry peduncular screw system used in 108 patients. Oswestry experiences

: Authors report on the control examinations of 108 patients on a peduncular system, known since 1986 and applied successfully in the operative treatment of various diseases of the lumbosacral spine. The results of healing of 69 patients in whom the fusion of the lumbosacral spine was performed because of long standing low-back pains are analysed. They describe also other possibilities given by the peduncular system, among others the correction and stabilization of the lumbar kyphosis in Becterew's disease, the postlaminectomy kyphosis and the lumbar scoliosis of adults. Cases of trauma and tumor in which this method of stabilization was also successfully used are also mentioned.
