Risk factors for refracture or new vertebral compression fractures after percutaneous vertebroplasty: a systematic review and meta-analysis.
Systematic Review
Osteoporotic vertebral compression fractures can substantially affect a patient’s life. Percutaneous vertebroplasty is a minimally invasive surgical procedure that can stabilize fractures, reduce pain, and increase the patient’s functionality. However, the incidence of secondary fractures post-surgery requires scientific attention. The risk factors that may lead to a new fracture postoperatively must be identified./r/nTo explore the possible risk factors that can predispose to a subsequent fracture after percutaneous vertebroplasty in patients with osteoporotic vertebral compression fractures./r/nSystematic review and meta-analysis./r/nWe systematically searched MEDLINE (PubMed), Embase (ScienceDirect), PEDro, and Cochrane databases from July 2013 through May 2024. The extracted data included patient and clinical characteristics, secondary fractures as the primary outcome, and prognostic factors. Eligible studies for synthesis included one group of patients who had suffered a new fracture after surgery and a group of patients who did not suffer any fracture after vertebroplasty (“non fracture group”). We used the software Medcalc and the web program Meta-Mar for all statistical analyses. SMDs were calculated for continuous data, and ORs were calculated for dichotomous data, both with 95% CI. To quantify statistical heterogeneity across studies, we used chi-squared tests and I2 statistics). The Newcastle-Ottawa Scale was used to assess the quality of studies./r/nA total of 3.821 patients from nine studies were included. Median follow-up was 21 months, and overall secondary fracture incidence was 16.6%. The meta-analysis showed that female gender [OR = 1.62, 95% CI 1,26; 2.07, z = 3.79, P = 0.0001], low bone mineral density [SMD = -0,30, 95% CI -0.52; -0.08, z = -2.65, P = 0.008], smoking [OR = 1.62, 95% CI 1.22; 2.15, z = 3.32, P = 0.001] and type 2 diabetes [OR = 1.40, 95% CI 1.11; 1.76, z = 2.83, P = 0.005] were significant risk factors for the secondary fractures after percutaneous vertebroplasty./r/nPatients with these identified risk factors should be monitored and treated accordingly to achieve the optimum prognosis after surgery.
