Abstract

PURPOSE:

The aim of the study was to evaluate the efficacy of an injectable and partly absorbable calcium bone cement (CERAMENT™, Bone Support, Sweden) in the treatment of osteoporotic or traumatic vertebral fractures by percutaneous vertebroplasty.

METHODS:

From March 2009 to October 2010 an open, prospective study in two centres was performed. 33 patients with symptomatic vertebral fractures were enrolled. Patients were included based on evaluation by X-ray, CT, and MRI. Clinical evaluation by Visual Analogue Scale (VAS, 0-10) and Oswestry Disability index test (ODI, 0-100 %) was performed before the operation as well as 1, 6 and 12 months after the procedure. Radiology assessment post-procedure was carried out by X-ray, CT, and MRI at 1, 6 and 12 months post-op. Intake of analgesic medications pre- and post-procedure was monitored.

RESULTS:

66 vertebral bodies underwent percutaneous vertebroplasty. VAS score demonstrated a significant decrease from 8.61 (SD 19.8) pre-operatively to 2.48 (SD 2.36) at 1 month. The score was 2.76 (SD 2.68) at 6 months and 1.36 (SD 1.33) at the latest follow up. ODI score dropped significantly from 58.86 pre-op to 26.94 at 6 months and further down to 7.61 at 12 months. No re-fractures or adjacent level fractures were reported.

CONCLUSION:

Data show that CERAMENT can be a substitute of PMMA in the treatment of osteoporotic and traumatic vertebral fractures, especially in young patients.
