The effect on the lumbosacral spine of long spinal fusion in adolescent idiopathic scoliosis was studied in 22 patients. The average duration of follow-up was 12.8 years. Corrections of the coronal curves through instrumentation were satisfactory. However, a kyphosis was produced at the fused segment of the lumbar spine in more than half of the cases. The unfused intervertebral spaces distally were hypermobile in extension, which probably indicated early disc degeneration. The incidences of back pain and radiological degeneration were found to be low. There was no relationship between back symptoms and type of employment, pregnancies or radiological degeneration. Preservation of normal lumbar lordosis during spinal fusions was emphasized.
对22例青少年特发性脊柱侧凸患者进行了长期脊柱融合术对腰骶椎影响的研究。平均随访时间为12.8年。通过器械矫正冠状面曲线效果令人满意。然而，超过半数的病例在腰椎融合节段出现了后凸畸形。远端未融合的椎间隙在伸展时活动过度，这可能提示早期椎间盘退变。背痛和影像学退变的发生率较低。背痛症状与职业类型、妊娠或影像学退变之间没有关联。强调了在脊柱融合术中保留正常腰椎前凸。
