The same procedure was performed in 14 patients during an 18-month period. The average age of the patients was 54聽years. All patients suffered severe pain before the surgical procedure (VSA mean: 7). Neurological deficiency was noted in 10 of the 14 patients with this spinal cord compression. Nineteen vertebrae were treated; a short posterior instrumentation was necessary in 11 patients. The average operative time was 90聽minutes. Of the patients with neurological deficiency, the clinical status improved after surgery in all. The average VSA of this series 3聽days after surgery was 2. The mean quantity of PMMA injected was 7聽cc. Two PMMA leaks, one in the intervertebral disc and one forward, were identified on the postoperative CT scan. The average hospital stay was 7聽days.
This procedure enables surgical decompression, vertebral body consolidation and consequently spinal stabilization of the spine. We did not have any complications related to this procedure which, particularly for the elderly population, is an attractive alternative to major surgery such as vertebrectomy.
