OBJECTIVE: to summarize the complications of posterior vertebral column resection (pVCR) and pedicle screw fixation for the treatment of @entity2003 . METHODS: fifty four @entity1 from a single center from February 2000 to February 2009 were included in this study. There were 23 males and 31 females with an average age of 28.3 years (range, 16-58 years). @entity1 were divided into 4 diagnostic categories: severe @entity1635 (n = 9, mean Cobb angle, 91.7  ), @entity3792 (n = 22, mean @entity1635 , 101.5  , and mean @entity1513 , 69.4  ), @entity1513 (n = 21, mean @entity1513 , 72.2  ), global @entity1513 (n = 2, mean @entity1513 , 93.6  ). All of the @entity1 received one stage pVCR combined correction with pedicle screws and circumferential fusion. Radiographs and hospital charts were reviewed to analyze the outcomes of correction. RESULTS: a mean of 1.4 vertebral levels were resected, the mean operative time was 470 min, and the mean @entity190 was 4180 ml. All the @entity1 were followed-up for an average time of 26 months (range, 12 - 66 months). At the latest follow-up, the major curve correction averaged: severe @entity1635 61.4   (67%), @entity3792 59.7   (56%)/ @entity1513 42.3   (59%), @entity1513 48.5   (71%), global @entity1513 62.7   (67%). A total of 21 complications (38.9%) occurred in 17 @entity1 , including 5 (9.3%) @entity16 happened in early stage and one case of delayed complete paraplegic. There were 11 (20.4%) non- @entity16 happened in early stage and 5 (9.3%) cases in late stage. CONCLUSIONS: one stage posterior-only vertebral column resection can achieve satisfactory correction of severe @entity85 with limited flexibility. Given its technically demanding and exhausting features, its potential risk of significant complications should be paid more attention.
