Abstract

Abstract:

With the progress of Chinese society and the intensification of population aging, osteoporotic fractures are rapidly increasing. The article discusses in detail the biomechanics of trabeculae and its application in the treatment of vertebral osteoporotic fractures. The vertebral body is the most common site of osteoporotic fractures, mainly composed of trabecular bone. The article first introduces the macroscopic structure and biomechanical properties of vertebral trabecular bone. Then, the important role of microstructure parameters of bone trabeculae in the morphological characteristics and mechanical properties of bone trabeculae was introduced. The focus is on the three-dimensional morphological parameters commonly used to quantitatively describe the microstructure of bone trabeculae, as well as the effects of bone trabecular heterogeneity, spatial connectivity direction, age growth, and gender on their mechanical properties. Subsequently, traditional and innovative diagnostic methods for osteoporotic lumbar vertebral compression fractures will be introduced. In terms of treatment, the article provides an overview of the advantages and disadvantages of various clinical treatments for osteoporotic fractures, including vertebroplasty, vertebral fusion, and percutaneous pedicle screw fixation. Finally, the innovative application of emerging technology 3D printing in spinal surgery was introduced, such as the use of 3D printing porous metal implants and biomimetic internal fixation devices. Combining 3D printing technology with traditional treatment methods can achieve better therapeutic effects and improve quality of life.
