髂肋肌

The two other main branches of the dorsal ramus are the intermediate branch, which sends fibers into the longissimus muscle,and the lateral branch, which innervates the iliocostalis muscle, the thoracolumbar fascia, the skin of the lower back and buttock, and the sacroiliac joint.29,136,137 At the superomedial border of the trans-verse processes where the lumbar medial branches are most amenable to blockade, these nerves are in such close proximity that anesthetizing any one of them will almost invariably lead to blockade of the others branches of the primary dorsal rami.

背侧支另外的两个分支是支配最长肌的中间支及支配髂肋肌、胸腰筋膜和下腰部皮肤，臀部及骶髂关节的外侧支。在横突上内侧缘，内侧支容易被阻滞，在此处的神经彼此距离很近，阻滞一支即可将其他背侧支一齐阻滞。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
