DescriptionUnreviewed

The radial sulcus ( also known as the musculospiral groove, radial groove, 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.

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.
