Clinical Analysis Of Surgical Treatment Of Degenerative Scoliosis

Objective: To evaluate the curative effect of surgical treatment of degenerative scoliosisand to compare different surgical options and segments selection which may contribute tothe outcome.Methods: A retrospective study was held from2010February to2013October in30patients who underwent operations for degenerative lumbar scoliosis in our hospital. Themean age of20females and10males was67years old(range56to83).All the patientsunderwent posterior approach operation, decompressive laminectomy, pedicle screwfixation and interbody fusion.30patients were divided into two groups:18cases for shortsegment group(A),12cases for long segment group(B). All the patients took standinglumbar antero-posterior and sagittal x-ray images pre and post-surgery and upon3month，6month and yearly follow-up. The Oswestry Low Back Pain Disability Questionnaire (ODI)was used to evaluate clinical outcomes.Results: Thirty patients were followed up for the whole process. Postoperative ODIimprovement rate was76.5%±6.5%in group A, and75.4%±8.7%in group B. Both werelarger than75%. One week after operation, X-ray film showed through the operation Cobbangle correction of group A was5.1°±2.8°; group B was14.6°±1.6°. A year after thesurgery Cobb angle progress of group A was2.6°±1°, group B was2.1°±1°.Conclusions: Surgical treatment is a good choice for the patients with degenerativescoliosis. Clinical symptoms and functional recovery can be improved through surgery.Long segment operation proved better in correcting scoliotic curvature. As time wentby,whether it was the short-segment group or the long one, neither of them could stop theprogress of Cobb angle．...
