Can you help me to segment the vertebral body of this lumbar spine?

在segmentCT椎体时, 相邻椎体之间的小关节的连接总是分不开, 下面这个椎体的CTclip, 我做了好长时间做不出理想的model, 谁来帮帮忙呀?

When segment CT vertebral bodies, the small joints between adjacent vertebral bodies are always inseparable. For this CT clip of the vertebral body below, I have been unable to make an ideal model for a long time. Who can help me?
