| Popis: | 101 It is recognized that, from clinical observations, current adapted locking bone plate system for fracture fixation of bone has good stability. Such system is characterized by the vertical angle locking of bone screws to the bone plate. However, it has a drawback of non-flexible angle locking design usually have problems particular in the area such as crushed bone or osteoporosis applications. The aim of this study is to design and develop an directional bone stabilization module for the fixture of long bone fractures via directional angular sleeve to improve the current clinical problem in the performing of angle screw replacement for bone fracture fixation. The system consists of three major parts: bone plates、bone screws and angle sleeve in this study. Based on the CAD software, we design and construct the module and evaluated the mechanical performance. Finally,the bone fracture fixation using finite elements analysis is compared to the bone plates available on the market. In this study, we complete the design and implement the prototype with the multi-directional and angular variable for bone stabilization module. Under the mechanical loading test, the prototype deformation is less than the market sold bone plate system and suitable for the use in adult body. From the finite element analysis results, our bone stabilization module has better fixation performance with the fracture face angle of 20°, around 47% less than the unit without face angle fixation. |
