Abstract

The present invention refers to the manufacture of a plate for closing the sternum intended for medical purposes, said plate being used for solving a public health problem caused by bone trauma accidents, where its main application is in the stabilization and fixation of fractures generated in the rib case wall. This process includes the fixation of the sternum following a sternotomy and surgical processes for reconstructing the sternum, with the purpose of helping to align and stabilise the bones. This plate was designed according to the body size, ergonomy and anthropometric measurements preferably in Latin people, taking care in that said measurements are correct for obtaining an accurate fixation in the sternum bone and avoiding friction problems. The manufacture of the pieces is based on a novel material best know as Polyether ether ketone (PEEK), with the purpose of having a material with suitable mechanical properties for the distribution of the loads presented in the breathing process, one of them being the flexion ability that is vital for avoiding discomfort in the patient when breathing, this being caused by a tension that obstructs a normal breathing action in the patient. Said material is biocompatible with the human body and easily operated in the surgery. With regard to the manufacture of the sternum closing plate, the costs were considerably reduced since high-resistance machinery is not required for performing the manufacture thereof. The plates are made by injection or die cut, then being sterilised by Gamma beams for being under suitable medical conditions.
