| Abstract | Patients with pathologic hip fractures or impending pathologic proximal femur fractures are at a high risk for developing bone cement implantation syndrome during cemented femoral arthroplasty. Comorbid conditions of patients who sustain these fractures, including cardiopulmonary compromise and permeable, highly vascular bone related to metastatic disease, put them at risk for sudden death. Reducing intraoperative intramedullary pressure, a modifiable intraoperative intervention, may decrease this risk. The goals of this study were to determine the pressure generated by low- and high-viscosity cement during femoral implantation and the pullout strength of the bone-cement-implant interface.Ten pairs of cadaveric femurs were divided into 2 groups: those receiving low-viscosity cement and those receiving high-viscosity cement during femoral arthroplasty. Pressure was recorded with sensors implanted in the lateral femoral cortex at proximal, middle, and distal implant positions in both groups during cement insertion and prosthesis implantation. Each construct underwent pullout failure testing after thorough cement curing. Significantly higher pressures were generated with high-viscosity cement for implant fixation, whereas the pullout force to failure was similar between groups.Low-viscosity cementation may be used to reduce the risk of bone cement implantation syndrome in high-risk patients with pathologic hip fractures or impending pathologic proximal femur fractures. The proposed mechanism of risk reduction is through lower intramedullary pressure with no bone-cement-implant interface pullout strength reduction. Further clinical trials are needed to prove this biomechanical effect. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
