OBJECTIVE: to explore the effectiveness and safety of @entity32459 ( @entity32459 ) for the management of @entity2003 . METHODS: from May 2004 to February 2008, 32 @entity1 with @entity2003 underwent @entity32459 were reviewed. There were 12 males and 20 females with an average age of 18 years (range, 10 - 56 years). The operation techniques included multilevel @entity27789 and residual intervertebral disc resection, followed by realignment and posterior correction with pedicle screws. The effectiveness was evaluated by preoperative and postoperative radiography and three-dimensional CT scan reconstruction at final follow-up. The intraoperative and postoperative complications of all @entity1 were recorded. RESULTS: a mean of 2.1 vertebrae were performed with @entity32459 and a mean of 10.6 vertebral levels were instrumented and fused (range, 8 - 13 vertebrae). The mean duration of surgery was 270 minutes (range, 215 - 380 minutes). The average intraoperative @entity190 was 1560 ml (range, 900 - 4800 ml). Complications were encountered in 4 @entity1 . There were 2 cases with transient @entity51 , 1 case with @entity2841 leak, 1 case with @entity4282 . The average time of follow-up was 31 months (range, 24 - 48 months). The correction rate was 61% on the coronal plane (from 108   to 42  ), and the correction rate was 65% on the sagittal plane (from 82.0   to 28.7  ). All @entity1 had solid fusion at osteotomy site, and no instrumentational failure and loosening were found over the follow up. CONCLUSION: single stage posterior @entity32459 is an effective option to manage @entity2003 .
