  • In the dissection of a 67-year-old Chinese male cadaver, a variant of the posterior cord was observed. The posterior cord was consisted of two parts. The upper posterior cord was the continuation of the posterior division of the upper trunk. It gave off the suprascapular nerve, the subscapular nerve, a communicating branch and then continued as the axillary nerve. The lower posterior cord was formed by the posterior divisions of the middle and lower trunks. After giving off the thoracodorsal nerve, the lower posterior cord fused with the communicating branch and continued as the radial nerve.
