Surgical outcomes of lumbar stenosis patients with osteoporosis at Hanoi Medical University Hospital
Nội dung chính của bài viết
Tóm tắt
We conducted a case series study on patients with lumbar spinal stenosis (LSS) and osteoporosis who underwent decompression and posterolateral fusion (PLF) at Hanoi Medical University Hospital over a 2-year period from September 2022 to September 2024. A total of 70 patients were included. The mean age was 67.61 ± 8.3 years old (range 43–82), with a female-to-male ratio of 2.5:1. Radiological findings revealed ligamentum flavum hypertrophy in 75.71%, disc height reduction in 71.43%. The most commonly affected level was L4–L5 (87.14%). Clinical outcomes showed significant improvement: mean VAS scores decreased from 6.8 ± 2.2 to 2.3 ± 0.9 for back pain and from 6.6 ± 2.3 to 1.9 ± 0.7 for leg pain. The Oswestry Disability Index (ODI) improved from 42.3% ± 12.6 preoperatively to 15.5% ± 6.6 at 6 months postoperatively (p < 0.001). The mean operative time was 138 ± 20 minutes (range 110–180), with mean intraoperative blood loss of 280 ± 21ml (225 – 350). The overall complication rate was 4.3%. The mean hospital stay was 7.4 ± 1.1 days (5 – 10), and the mean time to ambulation after surgery was 3.5 ± 1.1 days (2 – 6). At 12 months, the results improved further, with excellent outcomes in 45.5%, good in 37.9%, and fair in 16.6%. Surgical decompression combined with posterolateral fusion (PLF) in osteoporotic patients with LSS resulted in significant improvements in pain and functional outcomes, with acceptable fusion rates and manageable complication risks.
