Abstract

Objective: Evaluate the results of treatment of spondylolisthesis in osteoporotic patients with nerve compression by spinal fixation surgery and posterior interbody fusion combined with injectable hollow pedicle screws with PMMA.

Subjects and methods: Retrospective study describing a series of cases of spondylolisthesis with instability and osteoporosis who were operated by posterior interbody fusion and spinal fixation by hollow pedicle screws with biocement injection (PMMA) at the Neurosurgery Department of Thong Nhat Hospital, Ho Chi Minh City from December 2016 to December 2021.

Results: In 69 patients who had surgery to treat spondylolisthesis and osteoporosis by cement injection in hollow pedicle screws, we obtained: preoperative clinical symptoms such as back pain scored on the VAS scale decreased from 7.2 points to 2.34 points (p < 0.05) and nerve root pain decreased from 6.3 points to 1.52 points (p < 0.05), neurogenic claudication decreased 68,12% to 7.2%, (p < 0.05). The level of recovery according to JOA at the preoperative time from 7.71 ± 1.78 up to 22.34 ± 3.50 at the postoperative time (p < 0.05), with great improvement in patients had 1 or 2 levels of lesions. Complications recorded at low rates include: cement leakage, surgical wound infection, and dural tear.

Conclusion: Treatment of spondylolisthesis in osteoporosis patients is improved with posterior interbody fusion surgery with cement injection in hollow pedicle screws.
