Abstract

Background: Posterior lumbar interbody fusion provides excellent nerve decompression surgery, creating stability and firmness for the spine. In Vietnam, there have not been many studies to evaluate the treatment effectiveness of this method. Objects: To evaluate the results of surgical treatment for lumbar spondylolisthesis by posterior lumbar interbody fusion in Can Tho Central General Hospital. Materials and methods: A descriptive, prospective study on 49 patients diagnosed with lumbar spondylolisthesis. Visual Analogue Scale, Oswestry Disability Index, before surgery and 6 months after surgery were collected and compared. Bone fusion was evaluated by CT Scanner at 6 months after surgery, according to Bridwell standards. Intraoperative and postoperative complications will be recorded and analyzed. Results: After 6 months, the VAS score in the back decreased from 6.49 ± 1.34 to 2.84 ± 1.58 and the VAS score in the leg decreased from 6.22 ± 1.53 to 1.78 ± 1.23. ODI decreased from 51.7 ± 13.0% to 13.9 ± 8.6%, this decrease was statistically significant (p < 0.001). The bone fusion rate reached 89.8% 6 months after surgery, and the treatment results of good and very good according to MacNab were 79.6%. Complications of foot arch rupture 2%; 4% nerve root damage, fully recovered 6 months after surgery. Conclusions: Posterior lumbar interbody fusion is a safe and effective method in treating lumbar spondylolisthesis, achieving high bone fusion rates, good neurological function recovery and low complications.
