Finite element analysis of finger joint implant: A review

In orthopedic surgery, a semi constraint hinged prosthesis is inserted between the metacarpal and the first phalanx of the index finger. The purpose of the Implants development to allow maximum joint flexibility, and reduce joint pain effectively. In this paper; first the review of all the related areas is carried and after that with help of an implant study on loading conditions, deformation and stresses is analyzed. The research contribution is the development of a new implant with brief literature review and aligning the implant development criteria with different prospective of literature. The data from Computer Tomography is imported into MIMICS software and then segmentation is performed. The 3-D model for the finger joints is developed using Solid works software. Fixation of the implant to the gap location was performed using MIMICS. The analysis of normal finger with respect to the implanted is done through ANSYS software. The materials were assumed to be homogeneous, isotropic and linear elastic. Additive manufacturing technology is used to finally manufacture the implant.
