Likewise, lumbar spinal stenosis is being treated with less invasive procedures such as interspinous process spacers. 同时，也正在使用创伤小的系统例如棘突间装置治疗腰椎管狭窄症。
Objective. Evaluation of vertebral augmentation combined with interspinous decompression procedure in the same sitting. 目的：评估椎体加强术联合棘突间减压装置在同一病例中的应用。
The ealuated implant is an interspinous spacer fixed to the spine by 2 polyester braids looped around the proximal and distal spinous. 待研究的融合器由椎间融合器和两根固定于上的聚酯带组成，这两根聚酯带分别缠绕于上、下椎体棘突用以固定。
On MRI, abnormal signals due to spinal cord compression, tears of posterior longitudinal ligament and interspinous ligament were demonstrated. MRI同时还显示了脊髓受压信号异常及后纵韧带、棘间韧带、椎间盘的撕裂。
