Abstract

Abstract:

BACKGROUND: Simple spinal decompression for lumbar degeneration-induced lumbar scoliosis spinal stenosis is difficult to obtain long-term efficacy. Because simple decompression is considered an iatrogenic lumbar instability, and can aggravate lumbar deformity. Posterior lumbar pedicle screw fixation combined with decompression and fusion obtained good curative effects in patients.

OBJECTIVE: To investigate the clinical efficacy of posterior decompression, internal fixation, and bone graft fusion with posterior pedicle screw system in the treatment of degenerative lumbar scoliosis with stenosis.

METHODS: A retrospective analysis was performed in 18 patients with degenerative lumbar scoliosis with stenosis who received surgical treatment from February 2009 to November 2012. These patients consisted of

6 males and 12 females, with a mean age of 62.2 years (range, 48-80 years). They had lumbar scoliosis with a mean Cobb angle of 28.6° and underwent posterior decompression, internal fixation, and bone graft fusion.

RESULTS AND CONCLUSION: All the 18 patients achieved satisfactory follow-up. The mean follow-up was 22 months. All patients were satisfied with treatment outcomes and had improved quality of life. The mean correction angle was 13.7° (range, 6.0°-28.4°) after operation. There was no failure of internal fixation, and no infected cases were found. These data inducated that posterior decompression, internal fixation, and bone graft fusion is one of the effective methods for treating degenerative lumbar scoliosis with stenosis.
