Surgical Revision rates of hooks versus hybrid versus screws versus combined anteroposterior spinal fusion for adolescent idiopathic scoliosis.
Spine, 2007Co-Authors: Timothy R Kuklo, Benjamin K Potter, Lawrence G Lenke, David W Polly, Brenda A Sides, Keith H BridwellAbstract:STUDY DESIGN: Multi-institution retrospective review. OBJECTIVE: To determine the Surgical Revision rates of hook, hybrid, anteroposterior, and total pedicle screw constructs for adolescent idiopathic scoliosis (AIS). SUMMARY OF BACKGROUND DATA: Much debate continues on the safety, efficacy, and cost of thoracic pedicle screws. Nonetheless, there are no large series that have evaluated the Revision rate of various constructs in AIS to determine the need for repeat surgery, and therefore, the added indirect costs and risks of additional procedures. METHODS: We retrospectively reviewed the Surgical case logs of 1428 patients with AIS at 2 institutions from 1990 to 2004, and the clinical records and radiographs of Revision cases. Patients were classified into 1 of 4 groups: hook, hybrid hook and screw, all pedicle screw, and combined anteroposterior fusion constructs. Overall, there were 65 (4.6%) returns to the operating room, or 55 (3.9%) cases after excluding infections without concomitant pseudarthrosis. RESULTS: Of the 65 Revision cases, there were 52 females and 13 males, at an average age at first surgery of 13.9 years (range, 9-18 years), and an average age at Revision of 14.7 years (range, 12-23 years). For the Revision cases, the average initial Cobb was 61.9 degrees (range 44 degrees -110 degrees ), and this was not statistically different within the cohorts (P > 0.05). In terms of Revision rate, all hook constructs had a higher Revision rate secondary to instrumentation failure when compared with screws, while both hook and hybrid constructs had an overall higher Surgical Revision rate when compared with screw constructs or anteroposterior constructs (all P

thrombosed dialysis grafts comparison of treatment with transluminal angioplasty and Surgical Revision
Radiology, 1995Co-Authors: C I Schwartz, C V Mcbrayer, J H Sloan, Patricio Meneses, W J EnnisAbstract:PURPOSE: To compare the usefulness of transluminal angioplasty coupled with thrombectomy versus Surgical Revision coupled with thrombectomy in the restoration and maintenance of flow in thrombosed dialysis access grafts. MATERIALS AND METHODS: Twenty-four patients undergoing 28 angioplasty procedures were retrospectively compared to 24 patients who underwent 33 Surgical Revisions with a minimum 12-month follow-up period. All patients had thrombosed upper-arm expanded polytetrafluoroethylene (ePTFE) grafts. RESULTS: Initial success rates were 88% for angioplasty and 87% for surgery. Mean primary patency for angioplasty and surgery was 4.6 and 3.3 months, respectively. Mean secondary patency for angioplasty and surgery was 5.4 and 4.5 months, respectively. These differences were not statistically significant. A significantly shorter hospital stay and lower anesthesia requirement were noted in the angioplasty group. CONCLUSION: Transluminal angioplasty coupled with Fogarty thrombectomy is an effective altern...
