AIM: Delayed treatment of adolescent idiopathic scoliosis (AIS) is common in Mainland China because of the lack of public education about health care resulting in the reluctance to undergo surgery. This leads to a high incidence of complex cases where surgeons may not be trained in advanced procedures. We report the efficacy of single-staged anterior and posterior spinal fusion for correction of severe AIS in China. METHODS: A retrospective review was performed of 31 consecutive cases in which patients were treated at the Orthopaedic Department of Changhai Hospital in Shanghai between 2001 and 2004 with a combined anterior and posterior spinal fusion with screws, hooks, sublaminar wires or cables. RESULTS: Thirty-one patients with AIS with Lenke type 1, 2, 3 and 4 curves were included for analysis. At least one of the curves was >or=90 degrees in each patient. The mean coronal and sagittal Cobb angles of the main thoracic curve were 98 degrees and 22 degrees before surgery, 50.5 degrees and 21 degrees after surgery, and 53.7 degrees and 24 degrees at follow-up, respectively. No neurological deficits or deaths occurred. Solid arthrodesis with coronal and sagittal balance was achieved in all patients. CONCLUSIONS: A single-stage anterior release and fusion and posterior fusion for treatment of severe AIS is good alternative to pedicle screws/vertebrectomy on the basis of risk-benefit balance, and can be performed by surgeons not experienced in more complex procedures. The risk of pulmonary complications may be preferable to the risk of severe neurological complications when thoracic pedicle screws are applied, especially when surgeons are not adequately trained in their use.
