Results Stress concentration was noted at the pedicle and posterosuperior part of the vertebral body near the pedicle.

结果椎弓根以及椎体后上方与椎弓根相邻部分为中区域。

A high-speed burr was used to decorticate the surface of C2 lamina and C1 arch.

使用高速球钻在C2椎板和C1椎弓表面皮质。

We suggest that posterior vertebrectomy through the pedicle of vertebral arch is the most safely way.

③后入路选择经过椎弓、椎体中部伤血管最少。

The patient underwent ALIF via a retroperitoneal approach and posterior percutaneous pedicle screw fixation at L4–5 (Fig. 1).

患者通过腹膜后径路接受了L4-5ALIF，并由经皮椎弓固定。

Objective: To discuss the axial image characters of spondyloschisis from vertebral articulations is the purpose of this article.

探讨腰椎椎弓峡部裂与椎间小关节在横断图像上的影像学特征。
