Finite Element Analysis for LCP plates

Abstract

The main assumption of modern orthopedics and trauma surgery is to return to full fitness with a short recovery period. Unfortunately, the emergence of lifestyle diseases such as osteoporosis, which is characterized by a decrease in the biological value of bone tissue, a greater number of road accidents and related injuries to the musculoskeletal system, and the increasing expectations of people with degenerative polyarticular changes to remain mobile, have significantly increased the demand for all types of implants and prostheses. Bone fixations pose a serious challenge for doctors, especially when the bone is also osteoporotic. Previous studies on innovative LCP plates (Locking Compression Plate), which are equipped with a special locking mechanism, show their advantage over traditional methods. They are characterized by very good bone stabilization, minimization of movement around the fracture site, faster bone growth, and consequently a shorter reconvalescence period for the patient and a greater chance of returning to full mobility. The subject of the work is the FEM analysis for bone fixation - LCP plate. Modern medicine is constantly looking for new possibilities to increase the effectiveness and shorten the treatment time, an excellent example of which are the LCP plates discussed in the work. The main goal of the work is to select the material and parameters for the plate fixing the shin bone and to create a model of the bone-plate system.
