      <study_design>Randomization: Randomized, Blinding: Not blinded, Placebo: Not used, Assignment: Parallel, Purpose: Treatment, Randomization description: Random function of Excel software based on patient file number will be used for randomization. Patients with spondylolisthesis were included in the Excel program based on the file number and were divided into case and control groups based on the random button. In total, there were two groups of 35 people. By entering the file number in Excel program, then the random number is selected from the data analysis command. This study has 2 groups that can be numbered from 1 to 2, respectively. We also want 35 people in each group. As a result, sequences 1 to 2 should be repeated 35 times each time. It is clear that the repetition of each number occurs once in each group, so select 1 for repeating each number and 35 for repeating the sequence. In this way, 70 units will be produced.</study_design>

      <i_freetext>Intervention 1: The work of vertebral fixation in the first group using the device method in the vertebral body using pedicular screws is located on the surface of the vertebrae L4-L5-S1 and in fact, in this group three vertebrae are fixed . (L4-L5-S1 fixation surgery using pedicular screws with L5-S1 interbody fusion with autologous bone graft). Intervention 2: Control group: The device is placed in the vertebral body using pedicular screws on the surface of L5-S1 vertebrae and two lumbar vertebrae are fixed (L5-S1 fixation surgery using pedicular screws with L5-S1 interbody fusion With autologous bone graft).</i_freetext>
