ABSTRACT
The goal of this article is to evaluate the effectiveness of surgical treatment in advanced lumbar spondylosis. The research involved 100 patients, 65 men and 45 women, treated at the Marian Weiss Rehabilitation Center in Konstancin, Poland, during the years 1995-1999. The patients were divided into three groups, in each of which a different treatment method was applied: Group A - bone spondylodesis without internal stabilizers; Group B - bone spondylodesis + transpedicular fixation; Group C - bone spondylodesis + interbody cage fusion + transpedicular fixation. An analysis of the result demonstrates that the best outcome for surgical treatment was obtained in the group using interbody cage fusion and transpedicular fixation, which to a large degree reduces the duration of immobility and allows for ealier commencement of rehabilitation.
