Abstract
ObjectiveTo analyze the risk factors for residual pain after percutaneous kyphoplasty (PKP) for osteoporotic vertebral fractures (OVF).
MethodsRetrospectively analyzed were the patients with OVC who had been treated at Department of Orthopaedic Surgery, The First Affiliated Hospital of Soochow University by single level PKP from January 2020 to December 2021. They were 40 men and 181 women, with an age of (69.6±8.2) years. By the pain score of visual analogue scale (VAS) on the postoperative day 3, they were assigned into 2 groups: a residual pain group (VAS≥4) and a control group (VAS<4). The general demographics, radiographic and surgical related data of the 2 groups were analyzed by single factor analysis, including their gender, age, bone mineral density, body mass index, glucocorticoid usage, follow-up time, duration of symptoms, fracture location, severity of fracture compression, intravertebral cleft, middle column involvement, thoracolumbar fascia injury, anesthesia method, puncture method, volume of bone cement injected, cement-endplates contact, pattern of cement distribution, cement leakage, vertebral height restoration, preoperative cobb angle and correction of cobb angle. The P<0.1 factors screened were further analyzed by the multivariate logistic regression to determine the final variables.
ResultsIn the present study, 19 patients were assigned into the residual pain group and 202 patients the control group. The univariate analysis showed that body mass index (P=0.059), intravertebral cleft (P=0.049) and thoracolumbar fascia injury (P< 0.001) increased the risk for residual pain. The multivariate logistic regression analysis showed that thora-columbar fascia injury was an independent risk factor for residual pain (OR=6.127, 95% CI: 2.240 to 16.755, P<0.001).
ConclusionThoracolumbar fascia injury is an independent risk factor for residual pain after PKP for OVF.
