Osteoporosis is a highly prevalent and one of the most debilitating and costly chronic diseases worldwide and it is also responsible for approximately 1.5 million vertebral fragility fractures (VCFs) a year.1,2,3 Most of the patients experiencing an osteoporotic VCFs remain asymptomatic or minimally symptomatic; however, a large part of these patients do experience significant pain, resulting in decreased quality of life and disability and mortality too.4 The consequences of these fractures include pain and, in many cases, progressive vertebral collapse with resultant spinal kyphosis. Minimally invasive procedures, namely, kyphoplasty and vertebroplasty, represent a recent advance to the treatment of osteoporotic VCFs.5,6,7 The aim of this study is to compare effects in terms of recovery and quality of life and to compare deformity prevention efficacy of kyphoplasty and conservative treatment in postmenopausal women with an osteoporotic VCF. The aim of this study is to provide an efficacy assessment of kyphoplasty as compared with standard conservative treatment in postmenopausal women (bracing immobilization).8,9,10 Patients and Methods We designed a retrospective case–control study on 110 postmenopausal women. Included in this study were patients who were diagnosed with postmenopausal osteoporosis according to National Osteoporosis Foundation (NOF) guidelines, with a recent (< 2 weeks) symptomatic osteoporotic vertebral compression fracture (VCF), no more than two (if any) old VCFs with no resultant kyphotic deformity, and whose treatment starts no later than 15 days from the VCF time. Study population was split in a surgery cohort and a conservative cohort according to the provided treatment. All patients were asked to fill in VAS, SF-12, and Eq. 5D questionnaires at different time points up to 12 months after treatment. Segmental kyphosis at fracture level was also measured for our analysis. Results Kyphoplasty-treated patients had lower back pain VAS scores at 1 month as compared with conservatively treated patients (p < 0.05). Eq. 5D questionnaire also showed a better quality of life at 1 month for surgically treated patients (p < 0.05). As for the SF-12 no significant difference was observed. At 12 months, scores from all scales were not statistically different between the two cohorts, although surgically treated patients showed better trends than conservatively treated patients in pain and quality of life. Kyphoplasty was able to restore more than 55% of the original segmental kyphosis, whereas patients in conservative cohort lost 6.67% of the original segmental kyphosis on average. Conclusion Kyphoplasty seems to be a safe and effective procedure in reducing back pain due to painful VCF. The kyphosis restoring effect is also extremely interesting and can be achieved only in the first days after fracture time. In conclusion, kyphoplasty is a procedure that offers a fast recovery and a better quality of life at 1 month after treatment, helping restoring segmental kyphosis after VCFs.11,12,13 Acknowledgments There was no external funding source and no funding source played a role in the investigation.
