Case Reports
Republished: Parapedicular vertebral augmentation with polymethylmetacrylate for pedicle screw loosening.
A 71-year-old man who had a L1/S1 posterior fusion revision surgery complained of increasing back pain 5 weeks after the open surgical procedure. The pain was initially estimated at 9/10 on the visual analog scale (VAS) and thought to be related to a right-sided L2 screw loosening. A right parapedicular vertebroplasty was performed and polymethylmethacrylate cement was instilled around the right pedicle screw, filling the anterior two-thirds of the vertebral body. ⋯ The pain further decreased at 1 and 3 months after the intervention (2/10 on the VAS). Vertebroplasty is a minimally invasive, accessible, effective, and long lasting treatment for compression fractures. We believe that this technique could also be indicated to treat pain related to low grade screw loosening in properly selected patients.

In order to maximize the therapeutic benefits of cognitive-behavioral therapy (CBT) for chronic pain, individuals need to be motivated to adopt a self-management approach. The Pain Stages of Change Questionnaire (PSOCQ) was developed to measure patients' readiness to adopt a self-management approach to chronic pain. The present study examined whether pretreatment and posttreatment PSOCQ change scores among chronic low back pain patients could predict 6- and 12-month follow-up outcomes, and the stability of posttreatment PSOCQ scores during follow-up. ⋯ Changes in patients' attitudes toward adopting a pain self-management approach may serve as one of the therapeutic mechanisms and predict long-term function. This study also revealed that changed attitudes toward chronic pain self-management remain quite stable over time. Adoption of beliefs consistent with chronic pain self-management during treatment may promote sustained benefits.
