STUDY DESIGN: Retrospective clinical study. OBJECTIVE: To retrospectively evaluate the safety and efficacy of one-stage spinal osteotomy in the treatment of severe and progressive @entity1635 ( @entity1635 ) associated with @entity602 ( @entity602 ). SUMMARY OF BACKGROUND DATA: For severe and @entity2003 , @entity4681 are often advocated for correcting the deformity. However, the safety and efficacy of one-stage spinal osteotomy in the treatment of severe and rigid @entity1635 with @entity602 have been unclear thus far. METHODS: @entity1 were treated by one-stage spinal osteotomy between September 2007 and June 2011 in our hospital. The clinical records were reviewed for demographic and radiographical data, operative time, intraoperative @entity190 , blood transfusion, perioperative complications, and functional outcomes. RESULTS: There were 18 females and 11 males with an average age of 15.5    3.6 years (range, 12-28 yr). Spinal cord was longitudinally split by a @entity5040 in 11 @entity1 (type I @entity602 ) and by a fibrous band in 18 @entity1 (type II @entity602 ). @entity1 were observed for a minimum of 24 months after initial surgical treatment with an average follow-up of 43.0    17.1 months (range 24-68 mo) from September 2007 to June 2013. The mean operative time and average @entity190 of type ISSCM was significantly greater than those of type II @entity602 (P < 0.05). The major curve was corrected from an average of 97.2     17.8   to 35.7     15.9  , a mean correction rate of 64.3%    11.0%. The average loss of correction at final follow-up was 2.9% for major curves. The overall complication rate was 24.1%, including transient @entity16 in 3 @entity1 , cerebrospinal fluid leakage in 2 @entity1 , @entity293 in 1 @entity1 and @entity397 in 1 @entity1 . CONCLUSION: Relative to multistage corrective surgery, one-stage spinal osteotomy is effective for the correction of severe @entity1635 and @entity602 without increasing the rate of surgical complications. However, surgical treatment of type I @entity602 does require more operating time and @entity190 . LEVEL OF EVIDENCE: 4.
