In clinical practice, we may encounter the situation that the facet joint gaps at the index level were stretched by an oversized artificial disc a, b the facet joints are labeled with arrows). Besides, the normal articular surfaces were parallel which could be observed in CT scan c, and we found that with the increment of intervertebral height, the articular surfaces at index level would form a certain angle d the angled facet joint is labeled with an arrow)
