2012年8月3日 · Dr. Ebraheim’s educational animated video describes the anatomy of the volar forearm part 1. 8 muscles of the volar forearm arranged into two groups. 3 deep, 5 superficial. 6 flexors, 2...

The antebrachial fascia surrounds the musculature of the forearm and divides it into mobile wad, volar, and dorsal compartments. Fascia surrounds the individual muscles and provides strong septal attachments to the radius, ulna, and interosseous membrane.

2021年1月25日 · When dividing the volar forearm into four layers, the superficial layer can be considered as (from lateral to medial) pronator teres, flexor carpi radialis (FCR), palmaris longus (when present), and flexor carpi ulnaris (FCU). These four muscles arise from the common flexor origin at the medial epicondyle.

An understanding of the forearm surface anatomy particularly bony prominence and the cross-sectional contour is important for effective reduction and safe application of a cast.

The metacarpophalangeal and interphalangeal joints are readily available for surface examination; the former are situated just distal to the prominences of the knuckles, the latter are sufficiently indicated by the furrows on the volar, and the wrinkles on the dorsal surfaces.

2022年6月29日 · After exiting the cubital tunnel, the ulnar nerve enters the volar compartment of the forearm passing on the anterior surface of the flexor digitorum profundus, under the flexor carpi ulnaris. At the middle of the forearm, it is reached by the ulnar artery and its satellite veins.

The anterior or volar compartment of the forearm contains eight muscles: five belong to the superficial group (pronator teres, flexor carpi radialis, palmaris longus, flexor digitorum superficialis and flexor carpi ulnaris), and three to the deep group (flexor digitorum profundus, flexor pollicis longus and pronator quadratus).

2016年9月3日 · Place the butt of the opposite hand over the medial epicondyle, with the palm on the anterior surface of the forearm: the thumb points in the direction of the pronator teres, the index finger represents the flexor carpi radialis, the middle finger represents the palmaris longus, and the ring finger represents the flexor carpi ulnaris (Figs. 4 ...

2016年6月12日 · Base of the volar surface of the second metacarpal bone. Supine with forearm fully supinated. Insert the needle at the proximal one-third of a line drawn between the palmaris longus tendon at the wrist crease and medial epicondyle. Flex the wrist. The muscle is superficial, slender, fusiform, and medial to the flexor carpi radialis.
