| Abstract |
Objective
The purpose of this study was to determine the efficacy of posterior lumbar interbody fusion (PLIF) with bone cement augmentation for elderly patient with osteoporotic spondylolisthesis.
Methods
Fourteen patients underwent PLIF with bone cement augmentation in cases ofosteoporotic spondylolisthesis. All patients had lumbar mechanical back pain by instability or neurological symptoms by accompanying spinal stenosis, but their neurological deficit was absent. The surgical procedure included postural reduction and bone cement-augmented pedicle screw fixations and cages insertion in both side with bone chip packing in disc space. Imaging and clinical findings, including the level of the vertebra involved, fusion rate, vertebral slippage restoration, clinical outcome and complications were analyzed.
Results
The mean follow-up period was 15 months. The mean pain score (visual analogue scale) prior to surgery was 7.14±0.78 which decreased to 2.5±1.34 at 7 days after surgery. According to modified MacNab’s criteria, 13 of 14 cases were satisfactory result (excellent and good). But there were 2 cases of bone cement leakage and 1 case of neurological symptom. Imaging study shows all of cases have complete fusion without fusion failure at following 12 months.
Conclusion
In the management of lumbar spondylolisthesis in patients with severe osteoporosis, PLIF with bone cement augmentation is effective and good procedure to reduce the clinical symptoms and complete fusion. |
