Abstract:
Objective To observe the clinical efficacy of minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) by Quadrant channel for grade Ⅱ and Ⅲ spondylolisthesis. Methods Forty-eight patients with grade Ⅱ and Ⅲ spondylolisthesis were treated with MIS-TLIF by Quadrant channel. The patients were followed up for 12 months, The visual analog scale (VAS), Oswestry disability index (ODI), intervertebral height and lose drop of anterior slippage reduction were assessed. Results Surgery was successfully completed in all the patients. The VAS, ODI, intervertebral height and vertebral slippage 1 week after operation were significantly improved compared with that before operation:(4.5 ± 0.8) scores vs. (8.6 ± 1.2) scores, (32.0 ± 1.3) scores vs. (46.0 ± 3.7) scores, (10.5 ± 2.2) mm vs. (4.6 ± 2.1) mm and (2.1 ± 2.0) mm vs. (11.2 ± 1.7) mm, and there were statistical differences (P<0.05). Compared with that of 1 week after operation, there was no significant change in 12 months:(2.1 ± 2.0) scores, (11.0 ± 1.1) scores, (9.8 ± 2.5) mm and (2.2 ± 2.0) mm, P>0.05. Patients did not have the complications such as nerve damage, loosening of internal fixation. Conclusions The MIS-TLIF is a safe and effective minimally invasive treatment for grade Ⅱ and Ⅲ spondylolisthesis by Quadrant channel.
