The occurrence of nonconformities in prosthetics or medical instruments as a result of the manufacturing process or final machining (finishing) may lead to the decision of not using them in the medical process. The present paper aims to analyze the welding reconditioning possibilities in order to ensure the necessary geometrical characteristics, using the method of finite element analysis (FEA), of the interlocking intramedullary nail prosthetics made of titanium or titanium alloys. After identifying the nonconformities, with the help of non-destructive examination methods, the prosthetics was sectioned in the interest area to eliminate the defect. The bearing area of the section in the welded seam and its shape must ensure the needed resistance in functioning for the reconditioned prosthetics. Starting from the size of the removed area, a range of constructive forms of the welded seam were analysed economically, technologically and in terms of resistance. After running the FEA, in order to assess the level of stress and displacement occurred in case of specific load, for the proposed models, resulted that welding reconditioning is a reliable solution in such situations.
