Posterier Hemivertebra Resction In The Treatment Of Congenital Scoliosis

OBJECTIVETo evaluate the clinical result of posterior hemivertebra resction and correction with transpedicular instrumentation for congenital scoliosis.METHODFrom July 2007-2009,eleven consective cases,including 6 males and 5 females,underwent posterior hemivertebra resction and correction using transepedicular instrumentation.The average age at sugery was 2.5 years ranging from 1 to 4.5 years. There were all 11 cases with fully segmented hemivertebra of pedicle screws and bone-tansplant.RESULTThe average follow-up was all above 1.5 years.The Cobb's angles in the coronal plane was corrected from 39.4°(25°～65°) to 16.4°(5°～25°) and 16.3°(0°～25°) at final follw-up,representing 58.4%(36%～84.6%) correction rate. All cases had bony fusion.There was no neurological complication,no implant failure,no rankshaft phenomenon or infection.CONLUSIONPosterior hemiretebra resction with instrumentation is a safe and effective treatment option for congenital scoliosis.Congenital scoliosis should be treated in early age.
