Retrosomatic spondylolysis is a very rare type of neural arch defects. In typical cases the defect is a vertical cleft of the pedicle, which is thought to be the result of two ossification centers. The authors present a case of retrosomatic spondylolysis with a segmentation defect of the corresponding vertebral arch structures. The follow-up of this child from age 7 to 12 seems to be proof for this defect to be a fatigue fracture quite similar to those in isthmic spondylolysis.
后体性椎弓峡部裂是一种非常罕见的神经弓缺陷类型。在典型病例中，缺陷是椎弓根的垂直裂隙，被认为是两个骨化中心的结果。作者报告了一例伴有相应椎弓结构节段性缺陷的后体性椎弓峡部裂病例。对该患儿从7岁到12岁的随访似乎证明了这种缺陷是一种疲劳骨折，与峡部裂性脊椎滑脱中的疲劳骨折非常相似。
