AIM: To examine the clinical and radiological follow-ups and results of the patients undergoing fusion procedure by unilateral versusbilateral pedicle screw fixation (PSF) along with transforaminal lumbar interbody fusion (TLIF).MATERIAL and METHODS: Fifty-four patients were included in the study. Thirty-three patients were operated with bilateral PSFand TLIF and 21 had unilateral PSF and TLIF. The patients were evaluated preoperatively, on the postoperative 15th day, 6th and 12thmonths, and at the time of last examination (38 months in average for all patients) using Visual Analogue Scale (VAS) and OswestryDisability Index (ODI). Fusion rates were examined with direct X-rays with flexion-extension dynamic views and 3D computedtomography (CT) scans.RESULTS: Operation times were shorter and blood loss was less in the unilateral PSF group. Fusion rates were similar in bothgroups with no statistical significance. For both groups, significant clinical improvement was observed based on the preoperativeand postoperative scores.CONCLUSION: Unilateral PSF along with TLIF procedure is an effective option in selected patients. We need prospective randomizedstudies with higher number of patients and longer follow-up periods for more reliable results.
