Abstract:
[Objective] To discuss the operation and clinical results about surgical treatment of scoliosis of thoracic hemivertebra and diastematomyelia of adolescent.[Methods]From Jan 2001 to June 2007,15 patients were treated with one-stage posterior hemivertebrae and osseous divide resection combined with transpedicular instrumentation and bone graft.There were 6 males and 9 females with an average age of 21.2 years(range 16 to 24 years).All cases were segmented hemivertebrae.Hemivertebrae were located at T11(n=3)and T12(n=12).The status of the spinal fusion,correction rate and instrumentation were evaluated after surgery.[Results]All cases were followed up for 19 to 45 months with an average of 34 months.Cobb's angles of the main curve were 52.3??3.8?before surgery,10.2??1.4? after surgery.At the final follow-up there was 1.6? loss of correction.The mean height was increased by 3.76 cm.The district of bone graft showed good bone fusion.The time of vertebra fusion was 3 to 5 months(mean 3.6 months).No instrumentation,spinal fusion failure or other severe complications were noted.[Conclusion]One-stage posterior hemivertebrae and osseous divide resection combined with transpedicular instrumentation and bone graft can achieve a satisfactory result for the treatment of scoliosis of thoracic hemivertebra and diastematomyelia of adolescent.It can be recommended in clinical practice because of a good stability of fixation and fine spinal fusion.
