Experimental comparison of constructions «spondylosyndesis-270» and «spondylosyndesis-360»
Objective: The purpose of our study was to compare the biomechanical properties of the «spondylosyndesis-270» and «spondylosyndesis-360» fusion methods and make a conclusion about the possibility of the clinical use of «spondylosyndesis-270».
Mаteriаls аnd Methods. Experimentаl study included three-series tests with humаn spine cаdаver specimens. The stаbility of spinаl segments with trаnspediculаr instrumentаtion wаs studied during mechаnicаl loаd similar «in vivo» conditions. We used a torsion and tensile load on cadaver discs and investigated the stability of screw fixation in both methods.
Results: the monolateral fixation with the banana-shaped cage provides a sufficiently level of stability
under compression and torsion load. However, the outcomes of the monolateral method of fusion was better. We recommend a using of spondylodesis-270 method for surgical treatment in case of degenerative lumbar spine disease.
