Abstract:
Objective To investigate the complications of three-dimensional correction surgery for scoliosis and the corresponding prevention and treatment strategies.Methods From December 2004 to June 2011,727 cases of scoliosis were treated by three-dimensional correction system.There were 245 males and 482 females,aged from 3 to 62 years (average,18.2 years).Coronal Cobb angles ranged from 32° to 142° (average,87.6°),and sagittal Cobb angles ranged from-10° to 75° (average,45°).Results All patients were followed up for 12 to 90 months (average,62.5 months).All patients underwent surgery safely.The coronal correction rate ranged from 55％ to 98％ (average,85.2％),and the sagittal correction rate ranged from 35％ to 67％ (average,47.5％).There were no major complications such as death and nerve injury,but occurrences of other minor complications were 113 times in 102 cases.There were 26 cases of instrumentation-related complication,including 5 cases of pedicle screw loosening,5 cases of broken screw,8 cases of broken rod,3 cases of hook loosening,and 5 cases of pedicle fracture; 14 cases of them occurred early after correction surgery for adult scoliosis.There were 65 cases of correction-related complication,including 36 cases of junctional kyphosis (21 cases of proximal junctional kyphosis,11 cases of which were neuromuscular scoliosis; 15 cases of distal junctional kyphosis,including 4 cases of Marfan syndrome with scoliosis and 6 cases of neuromuscular scoliosis),22 cases of adding-on phenomenon,and 7 cases of flat back.Internal medicine complications included 6 cases of superior mesenteric artery syndrome and 7 cases of pulmonary complications.Operation-related complications included 4 cases of pressure sore and 5 cases of wound infection.Conclusion Accurate procedures of diagnosis and surgery for scoliosis are the key to decrease and prevent the complications.For adult scoliosis,enough instrumentation should be placed at the apical segments to decrease instrumentation-related complications.For neuromuscular scoliosis and Marfan syndrome with scoliosis,appropriate extension of fusion segment can effectively decrease junctional kyphosis.
