 EXPOSURE OF THE ULS NERVES   (Site not responding. Last check: 2007-10-21)
The median nerve passes behind the flexor superficialis arch and comes to lie deeply in the middle of the volar surface of the forearm, between the flexor digitorum superficialis and the flexor digitorum profundus muscles.
The ulnar nerve throughout the forearm is in the plane between the flexor carpi ulnaris and the flexor digitorum profundus muscles.
The relationship of the branches at the level of the supinator muscle is inconsistent; therefore, care must be exercised in identifying the branches during decompression of the posterior interosseous nerve as it enters the supinator muscle.

The flexor digitorum superficialis is a large muscle located beneath the flexor carpi ulnaris.
It arises from three immovable muscles - one from the middle inside of the humerus (upper arm bone), one from the middle inside of the ulna (longest forearm bone), and one from the radius (shortest forearm bone).
Its movable end is in the tendons of the fingers and acts to flex the fingers and, by a combined action, to flex the hand.

 Muscles of the Forearm
The superficial flexor muscles all arise from a common tendon attached to the medial epicondyle of the humerus, known as the common flexor attachment.
All of the flexor muscle, except for the brachioradialis (which is supplied by the radial nerve), are supplied by the median and ulnar nerve.
The remaining nine muscles are all extensors and are all innervated by the radial nerve.

 Anatomic Predisposition to Carpal Tunnel Syndrome
The lumbrical muscles usually originate from the radial sides of the tendons of the flexor digitorum profundus at the level of the metacarpals, which is distal to the carpal tunnel.
The normal distal insertion of the flexor digitorum superficialis muscle belly usually becomes four tendons proximal to the carpal tunnel through which it enters as tendons.
The surrounding palmar fascial aponeurosis (with possible aberrant muscle attachments and its connections with the flexor retinaculum that overly the carpal tunnel, and the antibrachial fascia over the flexor digitorum superficialis) represent areas where fascial release, friction massage and, most recently, Graston technique has0 shown to be beneficial in the treatment of CTS.

In a simple case, such as a small muscle located in the the distal part of a limb, this nomenclature is uncomplicated: muscle origins are proximal (towards the body) while muscle insertions are distal (away from the body).
However, with muscles that are located within the trunk of the body and which serve to flex the body, it is not easy to distinguish origins from insertions.

At the right antecubital fossa, the right MN enters the forearm, passing between the two heads of the pronator teres muscle, and passes deep with respect to the flexor digitorum superficialis muscle (FDS).

At the distal edge of the retinaculum, the MN is seen to divide into the radial and ulnar terminal divisions branches.

Post-operatively, the patient underwent intensive physiotherapy for stretching of the contracted tendons and for restoration of finger flexor power as she was left only with the flexor profundus.
The contracted muscles were enveloped but not infiltrated by tumor tissue and there was a clear plane of dissection between the tumor and enveloped muscles.
Though cysticercus infiltrates of muscles are usually asympto-matic, the excised muscle mass was pale and fibrotic.

On median nerve stimulation at the elbow a low compound muscle action potential with an increased distal latency was recorded over flexor digitorum superficialis muscle in the right side (right: amplitude 1 mV, latency 9.0 ms, left: amplitude 7 mV, latency 3.2 ms).
On clinical follow-up four years later a partial recovery of forearm muscle strength could be noted and the patient was free from pain.

Distribution of the forces produced by motor unit activity in the human flexor digitorum profundus -- Kilbreath et al.
In humans, the flexor digitorum profundus (FDP), which is a multi-tendoned muscle, produces forces that flex the four distal interphalangeal joints of the fingers.
The discharge of single low-threshold motor units (n = 69) was recorded at sites across the muscle during weak voluntary grasping involving all fingers and spike-triggered averaging of the forces under each of the finger pads was used to assess the distribution pattern.
