Risk factors predicting the new symptomatic vertebral compression fractures after percutaneous vertebroplasty or kyphoplasty

Introduction Percutaneous vertebroplasty (PVP) and percutaneous kyphoplasty (PKP) are effective procedures to alleviate pain caused by osteoporotic vertebral compression fractures (VCFs). New vertebral compression fracture (NVCF) has been noted as a potential late sequela of the procedures. The inci...

Description
Summary:Introduction Percutaneous vertebroplasty (PVP) and percutaneous kyphoplasty (PKP) are effective procedures to alleviate pain caused by osteoporotic vertebral compression fractures (VCFs). New vertebral compression fracture (NVCF) has been noted as a potential late sequela of the procedures. The incidence of NVCFs and affecting risk factors were investigated. Materials and methods The authors retrospectively analyzed the occurrence of NVCFs in 147 patients treated with PVP or PKP for osteoporotic VCFs. Possible risk factors, such as age, gender, body mass index, bone mineral density (BMD), location of treated vertebra, treatment modality, amount of bone cement injected, anterior–posterior ratio of the fractured vertebra, cement leakage into the disc space, and pattern of cement distribution, were assessed. Results Twenty-seven patients (18.4%) had subsequent symptomatic NVCFs with a median time to new fracture was of 70 days. The 1-year symptomatic fracture-free rate was 85.0% by the Kaplan–Meier estimate. Eighteen (66.7%) of the 27 patients had an NVCF on the adjacent vertebra. Significant differences ( P
