Teaching model for tibial plateau fractures in department of osteology

Abstract

The invention belongs to the technical field of medical devices and particularly relates to a teaching model for tibial plateau fractures in the department of osteology. The teaching model comprises a model body similar to the anatomic forms of the tibial plateau and the proximal end of the fibula; the model body is divided into a medial column, an intermediate column, a lateral column and a fibular column in sequence from the tibia to the proximal end of the fibula. The teaching model has the advantages that the teaching model is divided into four columns and nine areas; when bone blocks in the nine areas are stressed by an external force at the tibial plateau, due to differences of anatomical characteristics and adhesion structures, different displacement directions and collapse representations can be generated; due to redistribution of the blocking model for the fracture of the tibial plateau fractures, the part and the significance of the fractures are easy to understand and the damage mechanism is convenient to understand; on the basis of specific damaged parts, an operation scheme is determined according to the areas and the types of the fractures, and the selection of bone fracture plates is directly determined.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a teaching model for orthopedic tibial plateau fractures. Background technique [0002] Tibial plateau fracture is a common and important clinical traumatic disease. Since the tibial condyle is composed of cancellous bone, it is prone to fracture or even collapse when it is squeezed or impacted by external force, resulting in varying degrees of genu varus and valgus deformity, often combined with meniscus Or ligament damage, leading to serious dysfunction of the knee joint. The subsidence and unevenness of the articular surface, joint deformity, exfoliation and necrosis of hyaline cartilage and instability of the knee joint after tibial plateau fracture are the main causes of traumatic arthritis of the knee joint. [0003] The goal of treatment for tibial plateau fractures is to achieve a stable, well-aligned, normal-moving, and pain-free knee that minimizes the occurren...

AI Technical Summary

Problems solved by technology

The common problems are as follows: 1. The classification system only includes X-ray data but not the three-dimensional overall shape, which cannot cover the fracture types caused by complex three-dimensional mechanisms; The repeatability is not high, it cannot be unified and standardized, and there are often individual differences among doctors, which leads to difficulties in judgment, which in turn leads to different treatment plans; 3. Without a unified coding system, it is difficult to communicate in academic exchanges, and it is impossible to achieve large-scale case statistics and Data compilation; 4. The description of fracture morphology by each classification relies on text description, and the repeatability is difficult to guarantee; 5. There is no index to measure the complexity of tibial plateau fractures
