Spinal Fracture Treatment: Finite Element Analysis Of Different Fixation Techniques

The spondylolysis is usually associated with the fracture occurring in the pars interarticularis of the neural arch of the vertebra. It is considered to be caused by the hyperextension or excessive rotation movement due to sports injuries and it is suspected to cause back pain to 50 % of the young athletes. If not treated, the fracture could worsen and develop into spondylolisthesis in 51-80% of all cases. When non-surgical conservative treatments are not successful, clinical intervention may be the solution. Our work aims to compare, through a finite element analysis, the surgical techniques representing the state of the art, such as Buck technique and the evolution of the Morscher technique, with a new design combining both methods to reduce the fracture as proposed by new developments in the Biomechanics Research Laboratory.
