- A detailed description of the anatomical variations of the median nerve in the carpal tunnel, including the bifid median nerve, was previously reported. The bifid median nerve is a cause of secondary carpal tunnel syndrome due to its relatively higher cross-sectional area compared with a nonbifid median nerve. Magnetic resonance imaging (MRI) and ultrasound can be obtained to show bifid median nerves, helping surgeons avoid potential surgical hazards.

Lateral Antebrachial Cutaneous Nerve (LABC) • Patient complaints of pain at the dorso-radial/lateral forearm/wrist area require examination of this nerve especially after previous surgery/injury to his area. • Provides sensation to the lateral cutaneous aspect of the forearm.• Originates from roots C5, C6, C7 and branches from the musculocutaneous nerve.ourse: The musculocutaneous nerve becomes the lateral antebrachial cutaneous nerve when the brachialis nerve branch forks off to innervate the brachialis muscle. The lateral antebrachial cutaneous nerve continues distally to innervate the lateral aspect of the forearm.

What is the Median Nerve? The median nerve is the nerve that runs through the carpal tunnel of the wrist and connects with the thumb and all fingers of the hand, with the exception of the little finger. This nerve originates with the cervical spine and is routed through the arm and forearm. The nerve gathers in compressed form to run through the narrow carpal tunnel and to the fingers. In addition to controlling sensation in the hand, it is also important to the general nerve function of the upper portion of the arm. In relation to the hand, the median nerve controls all sensation and nerve function on the palm side of the thumb. The nerve also manages the process of sensation for the index and middle fingers, and half of the ring finger.

radial nerve radial nerve. radial nerve n. A nerve that arises from the posterior cord of the brachial plexus and divides into two terminal branches, designated superficial and deep, that supply muscular and cutaneous branches to the dorsal aspect of the arm and forearm. Examples from the Web for radial nerve.

Lateral cutaneous nerve of forearm The lateral antebrachial cutaneous nerve (or lateral cutaneous nerve of forearm) (branch of musculocutaneous nerve, also sometimes spelled antebrachial) passes behind the cephalic vein, and divides, opposite the elbow-joint, into a volar and a dorsal branch. Contents.t supplies the skin of the lower two-thirds of the dorso-lateral surface of the forearm, communicating with the superficial branch of the radial nerve and the dorsal antebrachial cutaneous branch of the radial.

Background The transverse abdominis plane (TAP) block is a peripheral nerve block designed to anesthetize the nerves supplying the anterior abdominal wall (T6 to L1). It was first described in 2001 by Rafi as a traditional blind landmark technique using the lumbar triangle of Petit (see the image below).

Sural nerve The sural nerve is a sensory nerve in the calf region (sura) of the leg. It is made up of collateral branches of the tibial nerve and common fibular nerve. Two cutaneous branches, the medial and lateral, form the sural nerve. The medial cutaneous branch arises from the tibial nerve, and the lateral branch arises from the common fibular nerve. The tibial nerve and the common fibular nerve arise as the sciatic nerve divides into two branches in the popliteal fossa.

Peripheral Nerve System • Lateral femoral cutaneous nerve – This nerve is part of the lumbar plexus nerve network. The lateral femoral cutaneous nerve provides sensation to the anterior and lateral sides of the thigh. • Median nerve – This nerve is a branch of the medial and lateral cords of the brachial plexus.

Median Nerve • The median nerve is critical to normal upper extremity function (but remains second to ulnar nerve in terms of the critical function provided to the hand). • Isolated median nerve injury is most debilitating for the loss of forearm pronation, loss of sensation at the pinch surfaces of the thumb and index finger; as well as the loss of index +/- long finger flexion and thumb function.

- The median nerve crosses from the distal forearm to the hand through the carpal tunnel. The walls and floor of the tunnel are formed by the carpal bones and the roof by the transverse carpal ligament (TCL). The TCL evolves from the antebrachial fascia at about the level of the wrist crease and extends 4 to 6 cm into the palm.

The Median Nerve The median nerve innervates the majority of the muscles in the anterior forearm, and some intrinsic hand muscles. The Anterior Forearm. In the forearm, the median nerve directly innervates muscles in the superficial and intermediate layers: Superficial layer: Pronator teres, flexor carpi radialis and palmaris longus.

Pudendal nerve entrapment Pudendal nerve entrapment (PNE), also known as Alcock canal syndrome, is an uncommon source of chronic pain, in which the pudendal nerve (located in the pelvis) is entrapped or compressed.Pain is positional and is worsened by sitting. Other symptoms include genital numbness, fecal incontinence and urinary incontinence.udendal nerve entrapment (PNE), also known as Alcock canal syndrome, is an uncommon source of chronic pain, in which the pudendal nerve (located in the pelvis) is entrapped or compressed.

Radial Nerve The radial nerve is an essential component of the correctly functioning upper limb. It innervates essentially all the muscles on the posterior aspect of our arms, and is therefore a large nerve. When we look at our evolutionary lineage, we must ask ourselves why we have such powerful elbow extensors (triceps brachii).

Bilateral third-nerve palsy with aberrant regeneration in GuillainâBarrÃ© syndrome Aberrant regeneration of the third nerve commonly develops several months after third-nerve palsy. Although third-nerve palsy occurs as a complication of Guillain–Barré syndrome in up to 17% of cases, most resolve without sequelae. We report a 9-year-old boy who developed signs of aberrant regeneration of the third nerve as a consequence of Guillain–Barré syndrome. Top of page.

Pudendal Peripheral Nerve Block Pudendal Peripheral Nerve Block. Pudendal nerve blocks are a minimally invasive, non-surgical treatment for chronic pain. These nerve blocks can help in the diagnosis of chronic pelvic pain conditions such as vaginal pain, penile pain, scrotal pain, or perineal pain. In addition, this pain management technique can also provide therapeutic relief by reducing pain signals originating from these nerves.

Clinical Communications: AdultsA Rare Case of Posterior Interosseous Nerve Palsy Associated With Radial Head Fracture We were able to find only a few reported cases of posterior interosseous nerve palsy associated with radial head fracture . The posterior interosseous nerve is a distal branch of the radial nerve with pure motor function in the forearm and hand. It splits off from the radial nerve above the elbow and courses deep in the forearm, innervating the supinator muscle and multiple extensor muscles in the wrist and hand.

- The sciatic nerve is composed of a lateral and medial division enclosed in a common sheath, with no exchange of fascicles. The lateral division is the common peroneal nerve or the lateral popliteal nerve, and the medial division is the tibial nerve or the medial popliteal nerve.

Nerve Compression Syndromes of the Hand The nerve innervates the pronator teres, flexor capri radialis, the FDS, and the 2 radial FDP tendons. It also supplies the FPL and the pronator quadratus. Within the hand, the motor branch of the median nerve supplies the opponens pollicis, the flexor pollicis brevis, and the abductor pollicis brevis musculature. It also supplies the 2 radial lumbrical muscles in the hand. The median nerve supplies sensation to the 3.5 digits on the radial aspect.
