... in the BPS group at 6 postoperative months. Postoperative dynamic X-rays and CT scans showed that the postoperative stability and fusion rate in both group (95.2% in UPS + TLFS versus 90.5% in BPS group) were excellent, and the position of the screws in our modified technique were satisfactory in all patients without violation of the spinal canal (Fig. 2).
