Biomechanical analysis of idiopathic osteodegenerative scoliosis of the lumbar spine through finite element analysis

The problems associated with the spine, especially in the lumbar area, have increased considerably in recent years, due to sedentary lifestyles and especially the office work that thousands of people have been forced to have due to the change in routine acquired by the pandemic of Covid-19. These events have caused hundreds of people to suffer from pathologies related to the spine, the most common being osteophytes and scoliosis, causing a lot of pain in the individual and even problems in the biomechanics of the patient. Many of the cases that are not treated immediately can get worse over time, even causing the patient to undergo surgery to solve their pathology. This is why to give an early prognosis of the evolution of the pathology over time and quantitatively provide the force and pressure parameters of the specific places in which there is a greater load and poor distribution of body weight in the individual, has developed the following study that using the data obtained and the simulation generated, an optimal model can be established to improve surgical strategies depending on the particular degree of the individual's pathology. In addition, in most cases, if this analysis is performed in an early diagnosis, the development of the pathology can be avoided, and that it increases to such a degree that surgical intervention is necessary. This is why the study is of great medical importance, the main objective of which is to contribute with a pre-clinical model for knowledge of pre-surgical improvement or even as an adjunct in rehabilitation methods since through simulation the specific place of the spinal damage. For this, the finite element analysis was used as a methodology that through the software mimics materialize, ansys (icem), gvin and abaqus it was possible to obtain a very reliable model for the analysis of the individual's pathology. Finally, with the help of the model, it was possible to determine the specific pressure points as well as to give an accurate diagnosis to improve the pathology, resulting in an imminent surgical intervention due to the pathological aggravations of the individual. Therefore, it can be concluded that the simulation obtained by finite element analysis is a simple, practical and economical method in addition to the prediction of damage in specific areas of the human body as well as defined parameters to reduce damage to the human body. spine. improving habits. In addition, it is a great ally in medical studies because it provides a wide variety of data on the composition and behavior of tissues or specific areas of study.
