Posterior Hemivertebra Resection In The Treatment Of Teenagers With Congenital Scoliosis

Objectives:To retrospective study the clinical effect of teenagers with congenitalscoliosis treated by posterior hemivertebra resection.Method:From June2007to June2011,24Teenagers at the age of12-20with congenitalscoliosis cured by posterior hemivertebra resection were reviewed.The average agewas15years old.All the patients underwent posterior hemivertebra resection.Results:The average operation time was2.5hours(range2-4hours)，and the averageblood loss was650ml(range400-1400m1)．An average age of follow-up period was19months(range12-30months)．Scoliosis was corrected form40.96°to15.21°with acorrection rate of62.86％.Kyphosis was corrected form27.04°to11.67°with orthopaedicrate of56.84％.Mean Cobb angle of the segmental main Curve was36.3°before surgery,14.4°after surgery, and15.3°at the last follow-up.There were only one pedicle cuttingwithout any sign of implant failure,pseudo arthrosis and correction loss.Conclusions:Posterior hemivertebra resection can get rid of the cause directly,has aeffective capability of correcting kyphoscoliosis on the frontal and sagittal planes.
