4,14) The variant ulnar artery descended through the entire forearm superficially, covered only by the skin, subcutaneous tissue and the antebrachial fascia.
4,14) In our subject the radial artery was covered only by skin and antebrachial fascia along its course in the forearm and did not run deep to the brachioradialis (Figure 1A).
For example, there are expansions of pectoralis major muscle to the brachial fascia, continuing via lacertus fibrosus and biceps muscle to the antebrachial fascia
and flexor carpi radialis, then to the flexor retinaculum, and finally to the palmaris longus muscle connecting to the fascia of the thenar eminence .
was incised along the same line.
After division the radial artery crossed median nerve superficially from medial to lateral side and then descended laterally to it, remained superficial lying just deep to brachial and antebrachial fascia
up to lower part of forearm from there onwards it had its usual course (Figure-2).
The shaft of distal radius was exposed after incising the deep antebrachial fascia
(Piermattei and Johnson, 2004).
In addition, the deep antebrachial fascia
was excised distally, therefore the nerve was decompressed adequately, which was confirmed by supinating and pronating the forearm intraoperatively.
The radial head attaches firmly to the entire medial border and caudal aspect of the radius, enveloped by a tough septum of the antebrachial fascia
This variant muscle originated from the posterior surface of the distal third of the shaft of the ulna, the adjacent interosseous membrane, and from the internal surface of the antebrachial fascia
occupying the interface of the superficial-deep forearm extensors (Figure IB).
Oommen (2002) has also recorded inverse (updown) palmaris longus muscle in a cadaver, in which the muscle originates by a long thin tendon from the medial epicondyle by the common flexor tendon and from the antebrachial fascia
in both limbs.
Examples of this type of fascia are observed in the limbs and are observed as fascia lata, crural fascia, brachial fascia, and antebrachial fascia
During routine dissection of an old male cadaver we observed an anomalous muscle was found to take it's origin from the antebrachial fascia
and flexor retinaculum, traversed ulnar canal (Guyon's) superficial to ulnar vessels and nerves to reach the proximal part of abductor digiti minimi.
