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.

The aim of this study was to compare the compressive forces generated by Dynamic Compression Angle-Stable Interlocking Nail (DCASIN) with those of traditional Dynamic Compression Plates (DCP) and Locking Compression Plates (LCP) using synthetic diaphyseal bone models (SDBM). Three groups were established based on the fixation method (G-DCASIN, G-DCP, and G-LCP), with implants fixed to SDBM simulating a transverse fracture, comprising 10 repetitions per group. A strain-gauge load cell was positioned in the SDBM gap to measure compressive forces in kilograms, recorded 30 s after the completion of each group-specific compression technique.

Objectives: This study aims to compare the biomechanical performances of five fixation techniques, posteroanterior (PA) screw, anteroposterior (AP) screw, posterior locking compression plate (LCP), anatomic posteromedial plate (PMP), and anterolateral plate (ALP), for isolated posteromedial tibial plateau fractures using cadaveric models under static and dynamic axial loading conditions.
Materials And Methods: Twenty-five fresh-frozen cadaveric tibias were used to create standardized posteromedial split-type fractures. Specimens were divided equally into five groups based on the fixation method.

This study investigated the biomechanical behavior of four different screw configurations used to fix comminuted proximal ulna fractures with a locking compression plate (LCP), via a detailed finite element model based on realistic anatomical geometry. The model incorporated realistic anatomical geometry including both cortical and cancellous bone, soft tissue constraints, and loading conditions representing the physiological self-weight of the forearm, with the humerus fixed at its proximal end. The stress distribution on the plate, strain intensity within the bone tissue, and interfragmentary motion (IFM) between fracture fragments were evaluated for each configuration.

The incidence of periprosthetic femoral fractures has increased in recent years. Osteosynthetic stabilisation is challenging, particularly for UCS IV.3-C fractures.
