The superficial branch of the radial nerve passes along the front of the radial side of the forearm to the commencement of its lower third. It is a sensory nerve. It lies at first slightly lateral to the radial artery, concealed beneath the brachioradialis.

2016年10月21日 · Originates from the radial nerve proper at the level of the radiocapitellar joint. runs distally in the forearm underneath the brachioradialis, lateral to the radial artery. it then divides into two branches: medial and lateral.

2023年10月14日 · The superficial radial nerve is a sensory nerve branch of the radial nerve that arises in the cubital fossa. It supplies sensory cutaneous innervation to the lateral portion of the dorsum of the hand.

The superficial branch of the radial nerve (SBRN) must be found and protected in surgical approaches to the distal radius and wrist joints. Its anatomical description has been cited in various treaties and atlas of surgical anatomy, although with minor differences between them.

2023年4月29日 · The superficial branch continues the course of the radial nerve and enters the hand from the radial side. This branch is also known as the "sensory branch" because of its primary role to provide sensation to the thenar eminence and dorsal aspect of the radial 3 and a half digits of the hand.

• Originates from roots C6, C7, C8 and branches from the radial nerve. Sensory examination includes testing the dorsal radial aspect of the distal forearm/wrist and hand innervated by the superficial branch of the radial nerve. • Ask patients to draw area of diminished sensation/numbness on a hand diagram.

2024年5月20日 · The fourth branch – the superficial branch – is a terminal division of the radial nerve. It innervates the dorsal surface of the lateral three and half digits and the associated area on the dorsum of the hand.

2024年7月16日 · The superficial branch of the radial nerve is a purely sensory branch of the radial nerve that provides innervation over the dorsal skin of the lateral side of the hand and dorsal surface of thumb, index finger and middle finger.

2024年5月4日 · The superficial branch of the radial nerve (SBRN) supplies sensation to the radial dorsal skin of the forearm and hand (see Figure 1). When this nerve is injured, it can lead to persistent neuropathic pain in these areas, resulting in discomfort and functional limitations.

The radial nerve terminally divides into its two superficial and deep branches in the cubital fossa at the level of the lateral epicondyle of the humerus. The superficial branch contains sensory nerve fibers from the C6—C8 cervical spinal segments.
