STUDY DESIGN: A retrospective case study was performed on the single-stage posterior transvertebral closing-wedge osteotomy for treatment of @entity1513 . SUMMARY OF BACKGROUND DATA: Forty-one consecutive cases in 38 @entity1 available for follow-up, averaging 33 months (range 4-87 months), are included. All @entity1 had severe @entity4512 ; 51% of cases had previous @entity174 , and 49% had postlaminectomy failed back syndromes with @entity1513 . A preoperative @entity51 was present in 34% of the cases including two with @entity1971 . METHODS: @entity1 examination and interviews, subjective questionnaire, chart reviews, and radiographic measurements were performed independently. Complications, risks, benefits, results, and biomechanical considerations were evaluated and discussed as compared with other techniques. RESULTS: All cases had solid union at follow-up; 93% maintained correction averaging 35 degrees with three requiring revision for failure. Postoperatively, 19.5% of the cases had new @entity51 with five (12.2%) temporary or minor and three (7.3%) major, including one with unimproved @entity451 at follow-up. Eight of the 14 preoperative @entity51 cases improved postoperatively; 26 additional surgeries were performed on 18 @entity1 most commonly for @entity158 ( @entity17011 ) and additional @entity130 (x 4). The subjective questionnaire results indicated significant @entity1 satisfaction, with 76% stating they would repeat the surgery and 90% recommending it to another. CONCLUSION: This technically demanding high-risk procedure provides an effective and mechanically superior correction for acute @entity1513 in selected adult @entity1 , with high subjective satisfaction.
