OBJECTIVE: To analyze the clinical features of @entity1635 associated with @entity1645 in adolescent @entity1 , and to explore the validity and safety of one-stage posterior approach and vertebral column resection for the correction of severe @entity1635 . METHODS: Between October 2004 and August 2008, 17 adolescent @entity1 with @entity1635 associated with @entity1645 were treated with surgical correction through posterior approach and pedicle instrumentation. There were 9 males and 8 females with an average age of 15.1 years (range, 12-19 years). The MRI scanning showed that 16 of 17 @entity1 had @entity1644 in cervical or thoracic spinal cord. Apex vertebra of @entity1635 were located at T7-12. One-stage posterior vertebral column resection and instrumental correction were performed on 9 @entity1 whose Cobb angle of @entity1635 or @entity1513 was more than 90 degrees, or who was associated with apparent @entity51 (total spondylectomy group). Other 8 @entity1 underwent posterior instrumental correction alone (simple correction group). All @entity1 ' fixation and fusion segment ranged from upper thoracic spine to lumbar spine. RESULTS: The operative time and the @entity190 were (384 +/- 65) minutes and (4 160 +/- 336) mL in total spondylectomy group, and were (246 +/- 47) minutes and (1 450 +/- 213) mL in simple correction group; showing significant differences (P < 0.05). In total spondylectomy group, @entity3459 occurred in 1 case, pleural perforation in 4 cases, and @entity358 in 1 case. In simple correction group, pleural perforation occurred in 1 case. These @entity1 were improved after symptomatic treatment. All @entity1 were followed up 24-36 months (32.5 months on average). Bony healing was achieved at 6-12 months in total spondylectomy group. No breakage or pulling-out of internal fixator occurred. The angles of @entity1513 and @entity1635 were significantly improved at 1 week after operation (P < 0.01) when compared with those before operation. The correction rates of @entity1635 and @entity1513 (63.4% +/- 4.6% and 72.1% +/- 5.8%) in total spondylectomy group were better than those (69.4% +/- 17.6% and 48.8% +/- 19.3%) in simple correction group. CONCLUSION: Suboccipital decompression before spine deformity correction may not always be necessary in adolescent @entity1635 @entity1 associated with @entity1645 . In @entity1 with severe and rigid curve or apparente @entity51 , posterior vertebral column resection would provide the opportunity of satisfied deformity correction and decrease the risk of @entity16 connected with surgical correction.
