| Abstract | Background The incidence of adjacent vertebral body re-fracture after percutaneous kyphoplasty (PKP) is associated with a number of variables, of which decreased bone mineral density is one of the major risk factors. Forearm bone mineral density (BMD) measurements are gaining attention because of their convenience and validity, but there is a lack of systematic research on the specific relationship between forearm BMD and the risk of adjacent vertebral re-fracture after PKP. Purpose To investigate the correlation between forearm BMD and the risk of adjacent vertebral re-fracture after PKP in osteoporotic vertebral compression fractures (OVCF) patients. Methods Retrospective evaluation of 198 OVCF patients receiving PKP was conducted in this study. The patients were divided into two groups: the no-fracture group and the re-fracture group, according to whether or not they had undergone vertebral re-fracture. Obtain basic information about the patient's age, sex, body mass index, bone cement leakage, smoking history, diabetes history, and surgical segmentation. Using computed tomography, the mean Hounsfield unit (HU) values for the BMD of the L1 lumbar spine were determined. For the dual-energy X-ray BMD test, the distal one-third lengths of the patient's nondominant forearm's radius and ulna were chosen. Receiver operating characteristic curves were utilized to evaluate the predictive value of forearm BMD versus lumbar CT values for vertebral re-fracture, and univariate and multivariate logistic regression analyses were employed to identify characteristics related with vertebral re-fracture following PKP. Results Re-fracture rate after PKP was 17.2% at a minimum 12-month follow-up. Significant differences were seen between the refracture and non-fracture groups in terms of hypertension, Cobb angle correction, vertebral height recovery rate, intradiscal cement leakage, forearm bone density, and vertebral HU values. In multifactorial logistic regression analysis, forearm bone density (OR 0.821; 95% CI 0.728–0.937, p = 0.008) and HU values (OR 0.815; 95% CI 0.733–0.906, p = 0.005) were independent risk factors for vertebral re-fracture. The area under the curve (AUC) for forearm BMD values and HU values predicting adjacent vertebral re-fracture were 0.956 and 0.967, respectively. Conclusions Forearm BMD is an independent risk factor for re-fracture of adjacent vertebrae after PKP. In addition, forearm BMD, as a valid indicator of postoperative re-fracture after PKP in patients with OVCF, and the HU value of lumbar spine CT were both powerful tools for predicting re-fracture. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
