Unilateral vertebral plate decompression,interbody fusion and pedicle screw fixation in treatment of lumbar disc herniation

Abstract

Objective:To explore the application and efficiency of unilateral vertebral plate decompression,interbody fusion and pedicle screw fixation in treatment of lumbar disc herniation.Methods:From Feb.2006 to Feb.2008,24 patients underwent unilateral vertebral plate decompression,interbody fusion and pedicle screw fixation.The patients were followed up for one year and the following data were recorded:operation time,estimated blood loss,duration of hospital-stay,short-term and medium-term clinical outcome.Results:All patients had their low back pain and/or lower extremity radicular pain improved during the one year follow-up.The last follow-up showed that the numbers of patients with Oswestry Disability Index(ODI) P0-P5 were 5,11,6,2,0,and 0,respectively.The clinical outcomes determined by modified JOA criteria showed that 18 patients had excellent outcomes,4 had good outcomes,and 2 had fair outcomes,with the excellent and good outcomes occupying 91.67%.Conclusion:The unilateral fixation can be used in patients with lumbar disc herniations who need lumbar spinal fusion.The medium-term outcomes is satisfactory.
