| Latin: | sulcus nervi radialis |
The radial groove (also known as the musculospiral groove, radial sulcus, or spiral groove) is a broad but shallow oblique depression for the radial nerve and deep brachial artery. It is located on the center of the lateral border of the humerus bone.[1] It is situated alongside the posterior margin of the deltoid tuberosity, ending at its inferior margin.[2]
Although it provides protection to the radial nerve, it is often involved in compressions on the nerve (due to external pressure due to surgery) that can cause radial nerve palsy.
