Project Overview

The goal is to make the process of open reduction internal fixation surgery more efficient and reduce the amount of space clamping requires during the operation. The goal of the project is to create a flexible device with a locking clasp that fits over a hole in a screw plate, that can be removed with an osteotome, and aids in alignment of the tie. The device should have the ability to clamp a 4.5mm LCP proximal femur plate to the femur during open reduction internal fixation surgery. The device is an adaptation of the structure used during a fracture repair operation on the femur, much like the ZIPFIX method used to close the sternum post-open heart surgery. The device must be radiolucent and not show up on an X-ray. The device should be able to withstand approximately 100N of torque applied by a bone drill with a factor of safety across the length of the plate. The flexible, locking clamp, should compress the area over the location where the screw will be placed to one side of the plate, and a locking, removable clasp should be off to the side for easy removal. The device should have a removable bevel on the tab to aid in alignment. Additionally, the accompanying apparatus used to tighten and clip the fixation device must be designed. The device should be sterile, disposable, and cost less than $100.
