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.
现代骨科与创伤外科的主要设想是在短恢复期内恢复到完全健康状态。不幸的是，诸如骨质疏松症等生活方式疾病的出现，其特征为骨组织生物价值下降、道路交通事故增多以及肌肉骨骼系统相关损伤增加，还有患有退行性多关节病变的人们对保持活动能力的期望不断提高，这些都显著增加了对各类植入物和假体的需求。骨固定对医生构成了严峻挑战，尤其是当骨骼同时患有骨质疏松症时。此前关于创新型锁定加压接骨板（LCP板）的研究表明，其配备特殊锁定机制，相较于传统方法具有优势。它们具有良好的骨稳定性、骨折部位周围活动最小化、骨生长更快的特点，因此患者康复期更短，恢复完全活动能力的机会更大。这项工作的主题是对骨固定——LCP板进行有限元分析。现代医学一直在探寻提高疗效和缩短治疗时间的新方法，本文所讨论的LCP板就是一个很好的例子。这项工作的主要目标是为固定胫骨的接骨板选择材料和参数，并创建骨 - 接骨板系统模型。
