Spiral Groove Of Humerus

The nerve trifurcates when comes in contact with the medial border of the humerus. Remaining two branches posterior antebrachial cutaneous nerve and rn travel along the spiral groove along with accompanying vessels.

The radial nerve contains branches from the mid and lower cervical spine.

Spiral groove of humerus. 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. Spiral groove of humerus fibrous arch attachment of triceps to humerus lateral intermuscular septum below deltoid insertion arcade of frohse. One of these branches is the branch to the medial head of the triceps and anconeus.

Radial groove subcostal groove. The radial nerve can be entrapped in several places in its path down the arm specifically in the axilla spiral groove of the humerus and near the lateral humeral epicondyle. The radial nerve is more commonly compressed in the spiral groove along the back of the humerus.

A broad shallow groove that spirals down the posterior surface of the humerus and marks the route of the radial nerve and the deep brachial artery. Deltoid tuberosity of the humerus the radial sulcus also known as the spiral groove is found on the posterior surface of the shaft and is a shallow oblique groove through which the radial nerve passes along with deep vessels. It is located on the center of the lateral border of the humerus bone.

Lower lateral cutaneous nerve to forearm. Above supinator below elbow branches above elbow above spiral groove humerus cutaneous nerves to arm. This is located posteroinferior to the deltoid tuberosity.
