The anatomy of the recurrent branch of the median nerve

  1. The median nerve was sep- arated into its branches and the recurrent branch isolated. The spatial relationship of the recurrent branch was recorded by its emergence from the me- dian nerve. The median nerve was depicted as a clock in cross-section and the origin recorded with reference to time
  2. The recurrent branch of the median nerve was classified into 3 types. Type I passed through the TCL; it is rare, occurring in 7% of the specimens. Type II nerves (74%) passed distal to the TCL through separate obliquely oriented fascia that originated on the TCL and inserted on the undersurface of the palmar aponeurosis

The median nerve is formed in the shoulder at the level of the collarbone by the confluence of several branches of nerves coming from the spinal cord. This part of the nervous system is called the brachial plexus and forms the major nerves that supply the entire upper extremity. 2 . The median nerve is one of these large nerves that travels. Purchase Now. A case is discussed in which carpal tunnel syndrome with an unusual course of the motor recurrent branch was discovered at operation. The importance of a careful dissection of the median nerve in this condition is emphasized Carpal tunnel syndrome is the most common compressive neuropathy that can be treated nonoperatively or surgically. If treated surgically, an awareness of the variations in the pattern of the recurrent branch of the median nerve is critical to avoid iatrogenic injury The median nerve also gives off a recurrent branch to the muscles of the thenar eminence : Flexor pollicis brevis, abductor pollicis brevis, opponens pollicis It is also known as the 'million dollar nerve' to signify its importance for basic hand function

Conduction velocities to the second lumbrical muscle were normal, excluding median nerve involvement proximal to the recurrent branch of the median nerve. These results are shown in table 1A,B.

After the fall he notes severe pain in the anatomical snuff box. Radiological studies reveal a fracture of the. Likewise, there may be a communicating branch between the median and ulnar nerves in the palm (the Riche-Cannieu anastomosis). In this setting, the ulnar nerve usually provides motor fibers to the recurrent branch of the median nerve to innervate the thenar muscles. Drawing of the course of the median nerve in the arm to the hand The recurrent motor branch of the median nerve is a radial structure at the level of the carpal tunnel and provides motor innervation to the muscles of the thenar eminence, including abductor pollicis brevis, opponens pollicis, and the superficial head of the flexor pollicis brevis. Of note, the deep head of flexor pollicis brevis and the.

Isolated compression of the recurrent motor branch (RMB) of the median nerve is not commonly reported. This report deals with a case of fascial band compression of the RMB of the median nerve with sparing of the sensory portion of the nerve in a single patient. The episode was precipitated by the subject was clearing fallen trees after an ice. The general longitudinal palmar incision could avoid injuries to the recurrent branch of the median nerve, and distal branches of palmar cutaneous nerve can be avoided macroscopically.

Carpal tunnel syndrome is a common presentation to surgical outpatient clinics. Treatment of carpal tunnel syndrome involves surgical division of the flexor retinaculum. Palmar and recurrent branches of the median nerve as well as the superficial palmar arch are at risk of damage. Thirteen cadavers of Sri Lankan nationality were selected The median nerve enters the hand through the carpal tunnel, deep to the flexor retinaculum along with the tendons of flexor digitorum superficialis, flexor digitorum profundus, and flexor pollicis longus. From there it sends off several branches: 1. Recurrent branch to muscles of the thenar compartment; 2 PurposeTo evaluate in a prospective study the possibility of visualization and diagnostic assessment of the recurrent motor branch (RMB) of the median nerve with high-resolution ultrasound (HRUS).Materials and methodsHRUS with high-frequency probes (18-22 MhZ) was used to locate the RMB in eight fresh cadaveric hands. To verify correct identification, ink-marking and consecutive dissection. When transverse carpal ligament (TCL) was transected, it was seen that the median nerve was divided to third common digital nerve and to the recurrent motor branch proximal to the distal end of the TCL, and an accessory transligamentous thenar branch about 1mm in diameter could be identified just proximal to the division a and b. The incision.

The median nerve also has an anterior interosseous branch that innervates the lateral part of the flexor digitorum profundus, flexor pollicis longus, and pronator quadratus. The recurrent branch of the median nerve innervates the thenar muscles, and the palmar cutaneous branch innervates the skin of the lateral part of the pal Skandalakis et al.) and an accessory branch that arises from the median nerve and joining with the recurrent motor branch etc. (Ogden, 1972). Presence of a separate tunnel in flexor retinaculum for recurrent motor branch is another variant (Johnson & Shrewsbury, 1970). The transligamentous variant that pierces the flexo The muscular thenar branch (MTB) or recurrent or motor branch of the median nerve (MN) is a short ramus of the MN originating from the anteroulnar aspect of the radial devision of the MN. In specific, MTB curves around the distal border of the flexor re-finaculum in order to supply usually the flexor pollici In the palm, the median nerve flattens at the distal border of the flexor retinaculum and splits into lateral and medial divisions. The lateral division gives a recurrent branch, which curls upwards to supply thenar muscles except the deep head of flexor pollicis brevis. It then splits into three palmar digital branches Median nerve innervates the majority of the muscles in the anterior forearm, and some intrinsic hand muscles. It innervates some of the muscles in the hand via two branches. The recurrent branch of the median nerve innervates the thenar muscles associated with movements of the thumb

All but the recurrent branch of median nerve originated in the forearm segment. In one sample, however, one of the muscular branches of the PT exited together with the sensory branches for the proximal radio-ulnar joint at the elbow (articular branches) 5 mm proximally to the epicondylar landmark An alternative angle to the motor branch; there is a clear depiction of it arising from the median nerve and its tortuous course. On identification of the recurrent motor branch, it was noted to trifurcate at the origin of the median nerve at and distal to the transverse carpal ligament (Lanz Classification 1A, 1B) A case is presented of an anomalous course of the recurrent motor branch of the median nerve and high division of the third common digital nerve seen in a limited open carpal tunnel release. Key words: Anatomical variation, carpal tunnel syndrome, median nerve The median nerve enters the hand by passing through the carpal tunnel as the most ventral structure (posterior to the flexor retinaculum), where it perhaps is the most commonly entrapped nerve in the body. At the distal end of the tunnel it separates into its terminal branches: the recurrent or muscular branch and multiple digital branches Pick up the median nerve at the proximal border of the flexor retinaculum then cut the retinaculum following the median nerve to the distal border of the flexor retinaculum. Identify the recurrent (motor) branch of the median nerve at the distal border of the flexor retinaculum; trace it into the thenar muscles Median Nerve. Once it passes through the carpal tunnel, the median nerve divides into 2 branches: the recurrent branch and palmar digital nerves.. The palmar digital nerves give sensory innervation to the palmar skin and dorsal nail beds of the lateral three and a half digits. They also provide motor innervation to the lateral two lumbricals.The recurrent branch supplies the thenar muscle group
