Intraoperative Electromyography and Instrumentation in Patients with Idiopathic Scoliosis
2016
IntroductionThe objective of this study is to relate the use of intraoperative electromyography surgical time, proper placement of screws, type of curve and time for screw in idiopathic scoliosis correction surgery in a group of surgeons of Belo Horizonte.MethodsThis was a retrospective study of 80 patients undergoing surgical treatment for idiopathic scoliosis correction between December 2008 and January 2015. All patients was performed electromyographic monitoring (EMG) intraoperative by a single column group of surgeons Belo Horizonte. EMG was performed with stimulation of pedicle screws in patients undergoing instrumentation using pedicle screws and fasteners.ResultsIt was observed that 85% were female, with a mean age of 17 years (minimum of 6 years and maximum of 34 years), 37.5% of the cases represented the curve was idiopathic Lenke 1AN. 60.0% of all surgical cases had EMG change, and of these 1.3% had already had deficits Pre-procedure and 3.75% of cases post deficits. Of the total cases analyzed...
