초록

The design and analysis of an elbow prosthesis using SolidWorks and Ansys R2 represents a significant advance in the field of clinical practice and biomechanics. This technology allows the creation of personalized devices for patients with irreparable conditions in the elbow joint, improving their quality of life. The study method was based on understanding the biomechanical foundations of the elbow joint and how osteoarthritis affects the patient's mobility and well-being. Once the model was designed based on anatomical considerations, exhaustive tests were carried out in the specialized software Ansys, in order to reach results that its resistance to stresses and deformations satisfactorily meets the conditions of the alloy used (6AI-4V ), concluding that for the support of postoperative loads and adaptation of the material it will not reach the elastic limit whose value referenced in the study of biomaterials for prostheses by Abdudeen et al. Which is recorded in the range of 850 to 900 Mpa [19] is not close to the maximum value of Von Mises stresses obtained in the static analysis of the present study, whose ceiling is around 10 Mpa, showing the resistance level of the designed prosthesis and select material.In conclusion, the design and static analysis by means of finite elements of the prosthesis for the humerus-ulna joint was a success with respect to the theoretical data of the biomaterial used, which represents a significant advance in the clinical field in these procedures that today are Day by day, with the expansion of technology, their presence in treatments for irremediable conditions such as elbow osteoarthritis is increasing in frequency.
