Theradial groove (also known as themusculospiral groove,radial sulcus, orspiral groove) is a broad but shallow oblique depression for theradial nerve anddeep brachial artery. It is located on the center of the lateral border of thehumerus bone.[1] It is situated alongside the posterior margin of thedeltoid 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 causeradial nerve palsy.[1]
