Carpal Radial Elevation

Carpal radial eminence: anatomical overview and functional role

The eminence carpi radialis, also known as the eminentia carpi radialis, is one of the anatomical structures that plays an important role in the movement and stability of the wrist. This anatomical region is located on the lateral (outer) side of the wrist and is key to many functions of the upper extremity.

The anatomical complex known as the eminence carpal radialis is composed of various bones, ligaments, and muscles. The main structures of this region are the radius, radial artery (arteria radialis) and radial nerve (nervus radialis). Additionally, many muscles are also present in this area, such as the extensor digitorum, extensor carpi radialis longus, and others.

The carpal radial eminence plays an important role in maintaining and controlling wrist movements. It provides stability and support for a variety of motor activities, such as lifting and lowering objects, flexing and extending the wrist, and rotating and tilting the wrist. This is possible thanks to the joint work of the bones, ligaments and muscles that form this anatomical complex.

When performing movements involving the elevation of the carpal radialis, the muscles passing through this space are activated and contracted, allowing control and control of the movement of the wrist. For example, the extensor carpi longradialis muscle is one of the main muscles responsible for raising and flexing the wrist. It begins at the eminence of the carpus radialis and connects to various tendons, allowing for a variety of movements and stability in this area.

One of the common problems associated with carpal radius elevation is injury or damage, which can occur as a result of injury, overexertion, or repetitive motion. Uncontrolled or incorrect movements can cause various conditions such as carpal tunnel syndrome or tenosynovitis, which can lead to pain, limited movement, and decreased functionality of the wrist.

To maintain the health and functionality of the eminence of the carpal radius, regular physical activity that strengthens the muscles and ligaments in this area is recommended. Stretching and strengthening of the muscles of the pre-eminence of the wrist radial - (eminentia carpi radialis, bna, jna)

Carpal radial elevation, also known as eminentia carpi radialis or BNA (major supraulnar amputation) in medical terminology, is a surgical procedure in which the upper part of the forearm is amputated, leaving the wrist and radius bone below the elbow joint.

BNA (carpal radial elevation) is an amputation technique that can be used in certain clinical situations, such as forearm malignancies or in cases of trauma where preserving the wrist and part of the hand is the patient's preferred option.

The BNA procedure involves removing the upper part of the forearm, including the elbow joint and part of the ulna, while preserving the wrist and radius bone. This allows the patient to maintain a certain level of functionality and mobility in the arm after amputation.

After a BNA procedure, patients may be offered rehabilitation interventions that include physical therapy and exercise training to restore arm strength and function. They may also use prosthetics or other assistive devices to improve their ability to perform daily tasks.

However, it is worth noting that the BNA procedure is a major operation and is only used in cases where other treatments are ineffective or impossible. The decision to use BNA is made by the physician based on each patient's individual circumstances and requires careful discussion and communication.

In conclusion, carpal radial elevation (BNA) is a surgical amputation procedure of the upper forearm that preserves the carpus and radius bone. This procedure may be considered as a treatment option in certain clinical situations, but requires careful evaluation and an individualized approach to each patient.

The carpal radial eminence is a musculoskeletal prominence in the wrist that forms between two eversion of its upper surface, called the pisiform tubercles: the pisiform symphysis and the scaphoid eminence of the greater tuberosity.

The elevation is fan-shaped and faces the cavity of the forearm. Its size is insignificant; the height is 5-6 mm, and the diameter is only 9-12 mm. The elevation area has 3 internal and 2 external ridges along its entire length. The surface of the elevation is smooth. The inner ridge is straight, arched, high and dense (the lateral one is larger than the inner one), the outer ridge is steep (the medial one is smaller than the lateral one).

Anterior to the eminence on the second metacarpal bone is the pisiform bone, on which the coronoid process is located above the pisiform notch, and below is the semilunar notch, separating the anterior and posterior surfaces of the pisiform surface. Medial to the pisiform there is an ulnar fossa.

The shape of the elevation can be constant or vary depending on various factors: width, height, span. Depending on the nature of the direction of the changed parameters, one of 3 types of structure may arise: the norm, in which the height is average and equal to 8-9 mm; increased (enriched, increased), in which
