Comparative Study of Unilateral Pedicle Screw Fixation versus Bilateral Pedicle Screw Fixation for Degenerative Disease in Lumbar Spine

Dr. Omprakash Kumar, Dr. Sunny Kumar, Dr. Abhimanyu Kumar, Dr. Rohit Raj

Abstract: Background: To compare unilateral pedicle screw fixation is better than bilateral pedicle screw fixation. Objectives: To compare Unilateral pedicle screw fixation is better than bilateral pedicle screw fixation in case of degenerative lumbar spine diseases. Methods: The clinical and radiographic outcomes were compared between the UPSF and BPSF group. The postoperative improvements were evaluated in either group. Intraoperative data such as duration of operation and estimated blood loss were compared. Results: A total of 20 cases were included in this study. The current best evidence detected shows no significant differences between unilateral and bilateral PSF for short segment lumbar fusion in the functional scores, length of hospital stay, fusion rate, and complication rate. . In all studied patients, 18 months after surgery, completed posterior spinal fusion was detected and recorded on a control CT, which was rated by Glassman. The average follow - up period was 15.2 ? 3.7 months, and the average age of patients was 57.2 ? 17.1 years. Both groups were comparable in age, gender (male to female ratio 17: 23 [1st group] and 19: 21 [2nd group]) (p > 0.05), and the operated segments L4 - L5: 34 patients (Group 1) and 35 patients (Group 2); and L5 - S1: However, unilateral PSF involved a remarkable decrease in operative time and blood loss. Conclusions: According to this systematic review, unilateral PSF is an effective method of fixation for short - segment lumbar fusion, has the advantages of reduced operative time and blood loss over bilateral PSF.
