Pain course in conservatively treated patients with back pain and a VCF on the spine radiograph (VERTOS III)
Little is known about the natural course of pain from vertebral compression fractures (VCF). In this study we evaluated the pain course in conservatively treated patients with back pain and a VCF on the spine radiograph. Between May 2007 and November 2008, 169 patients with back pain referred by the general practitioner for spine radiographs and with a VCF were requested to participate in this follow-up study. Base line questionnaires about visual analogue scale (VAS) score, type of treatment and use of osteoporosis medication were filled in by 82 patients. Questionnaires were repeated at 6 weeks, and at 3, 6 and 12 months. Significant pain relief was defined as a decrease in VAS score of 50 % or more from baseline. At baseline, mean VAS score in 82 patients was 6.9 (SD 2.0). Significant pain relief at 12 months was reported by 44 patients (54 %) while in 38 patients (46 %) pain relief was insufficient. No predictors for pain relief could be identified. Patients with insufficient pain relief at 12 months used significantly more analgesics and in these patients physiotherapy did better than other types of therapy. More than half of conservatively treated patients with back pain and VCF had sufficient pain relief at 12 months with most pain decrease in the first 3 months. However, a substantial proportion of patients still reported disabling pain. There were no predictors for the development of chronic pain. Patients with continuing pain ≥3 months after diagnosis of VCF may be candidates for vertebroplasty.
