ABSTRACT

Comparative study to evaluate bone consolidation and clinical results in posterolateral arthrodesis with autogenous bone graft vs stabilization with transpedicular screw in vertebral spondylolisthesis 5. This study was carried out in the Hospital Juarez de Mexico, SSA, from January 1999 to December 2000, in 18 patients with vertebral displacement 5, isthmic type, lytic variety, in I/II degree Meyerding classification, or 20%-40% according to Taillard classification, with angular vertebral instability 5. Uni-or bilateral lumbosciatic in patients of both sex. In 12 patients, we carried out posterior decompression and posterolateral arthrodesis with autogenous bone graft, which included articulate facet and stabilization with transpedicular screws at 5, with reduction of spondylolisthesis. We treated six patients with only posterior decompression and bone graft without screw stabilization and reduction. Results: All patients with screw stabilization had immediate satisfactory evolution without pain and walked within the first 48 h. All patients without screw stabilization, needed orthopedic support and rest for 3 months. Screw stabilization has a greater advantage for this kind of patient.
