Spondylodiscitis - Surgical Treatment
 Včelák, Josef ; Chomiak, Jiří (advisor) ; Chaloupka, Richard (referee) ; Štulík, Jan (referee)
Introduction: (Experimental part). Hypothesis evaluates the quasi-static risk of transpedicular fixation failure in the spinal cadaver with anterior column defect due to the fixation extension and defines the risk of transpedicular fixation failure due to screw convergence in cyclic loading. (Clinical part). Hypothesis evaluates the risk of isolated dorsal approach to ventral lumbar spondylodiscitis due to clinic and radiopraphic results and the risk of anterior radical debridement due to using titanium implant in the site of bone infection. Methods: (Experimental part). Four anatomically preparated spinal cadavers with anterior spinal column defect transpediculary instrumented were quasi-statically tested on MTS 858,2 Mini-Bionix. Concept of cyclic loading part were based on ASTM standard F1717. (Clinical part). The group A consisting of 23 patients was treated only by dorsal transmuscular approach and the second group B consisting of 8 patients was treated by two-stage postero- anterior surgery in lumbar spondylodiscitis. Results: (Experimental part). There were progress in all assessed parametres with considerable asymmetry direction in extension to flexion and duction in spinal column loading with anterior defect during quasi-static loading. The rod deformation decrease with extent of...
