Effect of gender on the evolution of pain and quality of life after treatment of symptomatic vertebral fragility fractures

Abstract

SummaryThe evolution of pain and quality of life after a symptomatic vertebral fracture differs according to patient gender, with a worse evolution in women independently of the treatment received.PurposeIn a previous randomized clinical study comparing the effect of vertebroplasty (VP) vs. conservative therapy (CT) on pain evolution and quality of life (QoL) of patients with symptomatic vertebral fractures (VF), we observed the development of chronic back pain in 23% of subjects, independently of the therapy received. This study analyses the effect of gender on the evolution of pain and QoL in these subjects.Methods118/125 randomized patients (27 males/91 females) with recent symptomatic VFs were evaluated. All received a standardized analgesic and antiosteoporotic format of treatment. Pain and QoL were evaluated by VAS and Qualeffo-41, respectively, at baseline, at 2 weeks and 2 and 6 months. We compared pain evolution and QoL after treatment (CT vs. VP) according to gender, and analysed factors including age, time of evolution, treatment received, baseline VAS, previous VFs (total and recent), incidental VFs, lumbar and femoral T-scores, and analgesic and antiosteoporotic treatment.ResultsAt baseline, there were no differences in age (males 74.8 ± 11.2 vs. females:73.2 ± 8.7 years), time of evolution, number of VFs (males:3.8 ± 2.4 vs. females: 3.1 ± 2.4), treatment received (VP, males:59%, females:45%), lumbar or femoral T-score, baseline VAS (males:6.8 ± 2.1 vs. females:6.8 ± 2.2) or Qualeffo score (males:52.2 ± 24.4 vs. females:59.7 ± 20.6). Pain and QoL evolution differed according to gender, being better in males. These differences were significant after two months independently of the treatment and the development of incidental VF during follow-up.ConclusionsPain and QoL evolution after a symptomatic VF differs according to gender, with a worse evolution in women independently of the treatment received.
