Summary
A 71-year-old man who had a L1/S1 posterior fusion revision surgical procedure complained of accelerating again ache 5 weeks after the open surgical process. The ache was initially estimated at 9/10 on the visible analog scale (VAS) and regarded as associated to a right-sided L2 screw loosening. A proper parapedicular vertebroplasty was carried out and polymethylmethacrylate cement was instilled round the precise pedicle screw, filling the anterior two-thirds of the vertebral physique. On postvertebroplasty day 1, the affected person had important enchancment in his low again ache. The ache additional decreased at 1 and three?months after the intervention (2/10 on the VAS). Vertebroplasty is a minimally invasive, accessible, efficient, and lengthy lasting therapy for compression fractures. We imagine that this system may be indicated to deal with ache associated to low grade screw loosening in correctly chosen sufferers.
