[The influence of segmental lumbosacral anatomy restoration on clinical outomes in the operative treatment of the isthmic spondylolisthesis].

The influence of lumbosacral spine segmental anatomy restoration on the outcome of the operative treatment of isthmic spondylolisthesis was taken into evaluation. A series of 55 patients (29 males and 26 females) was examined. The long-term follow up period exceeded 3 years. The Oswestry Disability Questionaire was used to evaluate the objective clinical condition of the patients, while for the subjective assessment an analog pain score and the two questions survey concerning the evaluation of success of the operative treatment and a possible agreement to a following operation if necessary were used. The presence of neurological radical symptoms was evaluated. The radiological assessment was consisted of the evaluation of the degree of spondylolisthesis, the angle of lumbosacral lordosis, the height of the interbody space and intervertebral foramen. In conclusions, the proper spine anatomy restoration had the influence on the improvement of the outcome of operative treatment of isthmic spondylolisthesis. A metal cage usage for the anterior interbody fusion of lumbar spine in the operative treatment of isthmic spondylolisthesis enables long-lasting proper anatomical relations of the fused segment.
