OBJECTIVE: Progressive @entity717 of the spine is rare and surgical treatment is challenging. Few reports have described surgical decompression, fusion, and partial correction by traditional 2-stage anterior decompression and the posterior fixation technique. The goal of this retrospective study was to report a series of 6 @entity1 with this deformity and the outcome after treatment by posterior-only 2-level vertebral column resection (PVCR). METHODS: Between 2011 and 2014, 6 @entity1 were treated for @entity85 with @entity717 . In these 6 @entity1 (2 males and 4 females), the diagnosis included 4 cases of @entity1513 and 2  cases of @entity4786 ; the distribution of spine level was from T4 to T11; the @entity1513 angle of the @entity1 was 115    (range, 107-125  ); the @entity1635 angle was 97   (range, 80  -117  ); follow-up ranged from 13 to 51 months (mean, 27 months). Four @entity1 developed progressive onset of @entity51 . All @entity1 underwent surgery by 2-level PVCR for decompression and correction of @entity3792 . RESULTS: Postoperatively, the @entity1 all had different @entity1513 correction rates, from 49% to 72% (mean, 63%) and @entity1635 correction rates, from 57% to 78% (mean, 65%). All @entity1 achieved successful spinal fusion with less than 3   of loss of correction at the latest follow-up evaluation. The 4 @entity1 with @entity51 improved 1 or 2 American @entity3510 Association scales at follow-up of at least 6 months. CONCLUSIONS: Two-level PVCR is a safe and efficacious surgical option for the treatment of @entity717 in @entity3792 and associated @entity51 .
