Abstract
Spondylolisthesis is a subluxation of vertebral body over another in sagittal plane. Incidence of Spondylolisthesis in general population is 5-7%. No matter what the etiology is, patients usually have significant functional disability. Few studies have investigated the long-term effect of pedicle screws fixation and posterolateral fusion on functional outcome. To assess the corrections of slip angle and meyerding grading after application of pedicle screw fixation and finally observed the neurological outcome & complications of the instrumentation and its efficacy. In our study, we have cases with age ranging from 35-60 yrs. The average age of presentation in 45 yrs. Post operatively we had 12 cases of grade 4 with return to grade one and 4 cases remained grade 4 and 6 cases with grade 1 remained grade 1 with reduced displacement. 2 cases of grade 3 return to grade 2. In our study, we had patients slip angles ranging from 10-50 o with 16 cases having slip angles from 25-50 o and 6 cases having slip angles from 10-30 and case had 55 o slip angle initially. In our study we had 10% neurological defects post operatively. Posteriolateral fusion is still a safe, promising and appealing technique. We found in our study that posterolateral fusion with Pedicle Screws fixation minimizes dislocation, achieves adequate decompression, corrects the sagittal axis, and accomplishes fusion. We successfully achieved solid fusion with good mechanical alignment in majority of the patients
