The forearm is anatomically divided into three compartments: the mobile wad, the volar, and the dorsal compartments (Tables 1 and 2). Tumor or infection may initially be contained in a single compartment.

2021年1月25日 · Maximum prominence of the radial styloid also can be somewhat difficult to assess radiographically, but the dorsal and volar lip of the sigmoid notch usually provide clear radiographic landmarks.

2022年6月29日 · Strong septal attachments of the antebrachial fascia to the radius, the ulna and the interosseous membrane divide the forearm into three distinct compartments – volar, dorsal and the so-called mobile wad – each of which house several muscles (Fig. 1).

Anatomy Of The Volar Forearm. These Eight Muscles Pronate The Forearm, Flex The Wrist, And Flex The Fingers And Thumb.

Although uncommon, compartment syndrome of the forearm is a well recognized diagnosis that can lead to significant morbidity and mortality if not diagnosed and treated early in the clinical course [2]. There are four compartments of the forearm: dorsal, superficial volar, deep volar, and …

Dorsal refers to the back side of an organism, while volar pertains to the front or palm side, particularly in the context of the hands and feet. This seemingly simple differentiation carries significant implications in fields ranging from anatomy …

The function of the volar compartment muscles is wrist flexion, digit flexion, and forearm pronation (27). The function of the dorsal compartment muscles is wrist extension, digit extension, and forearm supination (27).

2023年7月31日 · Many transcription factors are activated at various stages, allowing the limb buds to develop. Connective tissue derived from the lateral plate of the mesoderm divides the forearm into extensor (dorsal) and flexor (volar) compartments.

Division of the forearm into the mobile wad, volar, and dorsal compartments provides a convenient and practical way to review its im- portant muscles, nerves, and vessels. The radial, median, and ulnar nerves and their branches traverse the forearm compart- ments. Compression or entrapment of these nerves may be caused by.

The anterior cubital fossa and distal biceps tendon are additional important proximal landmarks; these are on the volar aspect of the forearm. These structures can be palpated in most individuals, guiding evaluation of the proximal forearm at its junction with the elbow joint.
