| Abstract | Introduction The purpose of this study was to determine if the use of specially designed screw hole inserts in empty locking screw holes improves the strength and failure characteristics of locking plates. Methods Forty-two 7-hole locking LC/DCP plates were mounted on cylindric UHMW Polyethylene blocks with a 1-cm gap between blocks, simulating a fracture with comminution and bone loss. 21 plates had a screw hole insert placed in the center hole (centered over the simulated fracture), while 21 of the plates remained empty in the center hole. The plate–block constructs were placed in a mechanical testing machine and subjected to loading conditions. The axial, bending, and torsional stiffness and displacements needed for the failure of each plate–block construct were calculated. The statistical analysis was performed using the Mann–Whitney U test for independent variables. Results All plates were then loaded to failure. There were significant differences in the axial load to failure (p = 0.017), bending load to failure (p < 0.01), and bending displacements (p < 0.01) of the test groups favoring the screw hole insert group as higher mechanical strength. Discussion/conclusion In conclusion, the study demonstrates that the addition of the specially designed locking screw hole insert does significantly change the strength of the locking LC/DCP plates and might be suggested in the clinical application. |

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.
