English Abstract:
  【Abstract】 Objective:To investigate the common causes and surgical strategy for revision surgery for adolescent idiopathic scoliosis.Method:10 patients underwent revision surgery due to failed primary spinal fusion surgery in our hospital from January 2003 to December 2008.Their detailed image data collected pre- and postoperatively,during the follow-up and the revision surgery,as well as the surgical strategies for both primary and revision surgery were collected and reviewed retrospectively.Result:Of 10 revision surgeries,fusion segments were extended due to progressive scoliosis in 5 surgeris;1 patient underwent proximal fusion extension due to proximal junctional kyphosis;3 patients had debridement and antibiotic therapy due to infection and instrument were maintained in 2 cases;1 patient underwent implant replacement and autograft due to pseudarthrosis and instrument failure.All 10 patients were followed up for 12~33 months(average,21.5 months).At final follow-up,no malalignment,no scoliosis progression and disimbursement and instrument failure were noted.Conclusion:The most common causes for revision surgery for adolescent idiopathic scoliosis are curve progression,infection,pseudarthrosis and abnormal proximal junctional kyphosis.Proper revision strategy can ensure satisfactory results.
