Abstract：Objective To study the short-term clinical results of posterior surgery for degenerative lumbar scoliosis, which consisted of posterior facet joint release, long segment fusion and intervertebral release followed by interbody cage implantation on the concave side at the apex of the curve. Methods From January 2009 to January 2012, 22 patients with degenerative lumbar scoliosiswere treated by posterior long segment fusion. The mean follow-up period was 18 months ( range:6-24 months ). The operation time, intraoperative blood loss, postoperative complications, preoperative and postoperative Visual Analogue Scale ( VAS ) and Oswestry disability index ( ODI ) scores, excellent-good rate and correction results on the coronal and sagittal plane images were analyzed. Results Themean preoperative Cobb’s angle was 41.6° ( range:31°-56° ), and the mean postoperative Cobb’s angle was 10.7° ( range:0°-15° ). The preoperative VAS and ODI were ( 7.3±2.4 ) points and ( 60.5±7.6 )%, which were improved to ( 1.7±1.4 ) points and ( 18.6±4.2 )%after the surgery, and the differences were statistically signiifcant ( P<0.05 ).The clinical excellent and good rate was 82.4%. During the follow-up, there was no occurrence of pseudarthrosis, cage displacement, loss of correction angle or loss of intervertebral spcae height. Conclusions The combination of posterior intervertebral release and interbody cage implantation on the concave side at the apex of the curve is found to be an effective and safe method for degenerative lumbar scoliosis.
