STUDY DESIGN: Retrospective radiograph and chart review of 28 @entity1 with adult @entity2112 undergoing primary corrective surgery. Clinical and radiographic parameters were assessed before surgery, after surgery, and at a 2-year follow-up assessment. A self-perceived outcome questionnaire was administered to the study @entity1 at a minimum 2-year follow-up assessment. OBJECTIVE: To assess @entity1 outcomes after surgery for adult @entity1635 using traditional radiographic parameters along with a self-perceived outcomes questionnaire. SUMMARY OF BACKGROUND DATA: The clinical and radiographic results and the outcomes for the surgical treatment of adult @entity2112 have not been established in the literature with respect to the use of modern third-generation instrumentation techniques. Most studies reviewing the surgical treatment of adult @entity2112 look primarily at Harrington instrumentation techniques. METHODS: Records and radiographs were reviewed retrospectively for all the @entity1 (n = 54) undergoing primary corrective surgery for adult @entity2112 between December 30, 1994 and December 30, 1997. Of the 54 @entity1 reviewed, 28 (52%) met the following inclusion criteria: age exceeding 20 years, primary surgery, fusion above the sacrum, availability of medical records along with preoperative, postoperative, and 2-year follow-up radiographs. Additionally, a self-perceived outcomes questionnaire was administered to these @entity1 at a minimum 2-year follow-up assessment. RESULTS: All the @entity1 were @entity1 (28/28). The indications for surgery were @entity158 and progression in 54% (15/28) and @entity158 in 29% (8/28) of the @entity1 . The average preoperative major curve measurement was 65 degrees (range, 38-98 degrees ). The average postoperative major curve measurement was 24 degrees (range, 5-59 degrees ), for a correction of 64%. The average follow-up curve measurement was 27 degrees (range, 3-60 degrees ), for a correction of 61%. Whereas 71% of the cases were anteroposterior, 29% were posterior only. There was one intraoperative complication among the 28 @entity1 and four postoperative complications in 3 of the 28 @entity1 . The self-perceived outcome questionnaires were available for 83% (23/28) of the @entity1 . Definite or probable relief of symptoms was reported in 74%(17/23). Improved ability to sleep was reported in 61% (14/23), and ability to return to their usual job was reported in 57% (13/23). Satisfaction with the results of surgery was reported in 87% (20/23). CONCLUSIONS: Surgery for adult @entity2112 using third-generation instrumentation techniques provides significant clinical improvement, @entity1635 correction, maintenance of sagittal alignment, and @entity1 satisfaction, with an acceptable complication rate.
