TREATMENT OF DEGENERATIVE LUMBAR SPONDYLOLISTHESIS WITH ORIGINAL POSITION OR REDUCTION FUSION / 解放军医学杂志

ABSTRACT

To observe the clinical outcome of degenerative lumbar spondylolisthesis treated by TFC, transpedicle instrument and bone graft, transpedicle instrument and TFC, respectively, from May 1995 to Aug. 2000, 106 patients with degenerative lumbar spondylolisthesis were conservatively treated. According to Meyerding classification system of lumbar spondylolisthesis, 56 cases were classified as degree 1, 47 cases as degree 2, 3 cases as degree 3. The patients were followed up from 6 months to 10 years and 2 months, averaged 38 months. According to different operative methods, the patients were divided into 3 groups TFC group, transpedicle instrument and bone graft group, transpedicle instrument and TFC group. Among the 31 cases in TFC group, 22 cases were followed up, the excellent rate was 95 5%. Among the 42 cases in transpedicle instrument and bone graft group, 35 cases were followed up, the anatomical reduction rate was 83%, the excellent rate was 94 8%. Among the 33 cases in transpedicle instrument and TFC group, 28 cases were followed up, the anatomical reduction rate was 81%, the excellent rate was 96 4%. According different indications, TFC and pedicle screw systems were all effective for spondylolisthesis. They had a lower complication rate. The use of spinal instrumentation is a valuable adjunct to achieve lumbosacral fusion in patients having undergone decompressive surgery for the spine.
