Acromioclavicular Joint AC Joint in shoulder, AC Joint Pain
The acromioclavicular ligament is part of the acromioclavicular joint. It is divided into two parts: superior and inferior: The Superior Acromioclavicular Ligament (ligamentum acromioclaviculare).—This ligament is a quadrilateral band, covering the superior part of the articulation, and extending between the upper part of the acromial end of the clavicle and the adjoining part of the upper.
Shoulder Joint Ligaments
Una parte de las fibras del músculo trapecio se fusionan con este ligamento, sosteniendo la cápsula articular desde su lado superior. De manera similar, el ligamento acromioclavicular inferior conecta las superficies inferiores del acromion y la extremidad acromial de la clavícula. Es más delgado que su contraparte superior y puede.

Da mesma forma, o ligamento acromioclavicular inferior liga as superfícies inferiores do acrômio e da extremidade acromial da clavícula. É mais fino do que o seu homólogo superior e pode sofrer perfurações com a idade. Tem particular importância em indivíduos cujas superfícies articulares da articulação acromioclavicular não são.

The AC joint represents a complex articulation between the distal clavicle and the anteromedial aspect of the acromion and plays an important role in the coordination shoulder motion and force transmission between the shoulder girdle and the axial skeleton (Fig. 7.1) [ 1, 2 ]. Because the clavicle is linked to the acromion, three-dimensional.

There are three types of disc 8-11: A weak, synovium-lined joint capsule is attached to the articular margins and is reinforced superiorly by blending fibers of the trapezius muscle 6. The acromioclavicular joint space measures 1-6 mm (females) and 1-7 mm (males), decreasing with age 12 . The acromioclavicular joint is one of the letter joints 13.

The coracoclavicular (CC) ligament serves as the primary support for the acromioclavicular (AC) ligament. Together, these 2 ligaments stabilize the acromioclavicular joint, which is one of the major shoulder joints. To better understand the role of the coracoclavicular ligament, it is necessary to understand the anatomy of the acromioclavicular joint. The acromioclavicular joint serves a vital.
LIGAMENTOS DEL HOMBRO Dolopedia
The acromioclavicular ligament is a ligament of the shoulder that surrounds the acromioclavicular (AC) joint between the acromion on the top of the scapula and the clavicle, or collarbone. It is divided into two parts: the superior acromioclavicular ligament and the inferior acromioclavicular ligament. Both parts of the ligament are made of.
PATHOLOGY OF THE ACROMIOCLAVICULAR JOINT (AC) ALAI
Background. The selection of the ideal reconstruction technique to treat acromioclavicular joint (ACJ) dislocations is still being discussed [].In biomechanical studies, anatomical reconstruction of the coracoclavicular (CC) ligaments has demonstrated superior primary stability and load to failure similar to native ligaments compared to non-anatomical reconstructions [2-4].

Anatomical Relations. The acromioclavicular ligament joins the upper aspect of the acromion of the scapula to the acromial (or lateral) aspect of the clavicle. Inferiorly, the ligament is thin. It provides an attachment for the articular disc of the acromioclavicular joint.
Articulacin Acromioclavicular
Acromioclavicular joint (Articulatio acromioclavicularis) The acromioclavicular (AC) joint is the articulation between the two bones of pectoral girdle; the clavicle and scapula.It is a plane synovial joint, with flat articular surfaces which are approximately the same in size.. Since there are no muscles that act directly on this joint, the movements within it are entirely passive.

The acromioclavicular joint is an important component of the shoulder girdle; it links the axial skeleton with the upper limb. This joint, a planar diarthrodial articulation between the clavicle and the acromion, contains a meniscus-like fibrous disk that is prone to degeneration. The acromioclavicular capsule and ligaments stabilize the joint in the horizontal direction, while the.

Biomechanically, the superior ligament was demonstrated as stronger than the inferior AC ligament, thus having an important role in controlling rotational and horizontal stability [2, 4, 5]. However, as the inferior ligament is often much thinner, anatomically, it should be considered more difficult to consistently detect and measure [3,4,5,6].

Abstract. Acromioclavicular (AC) joint injury is a frequent diagnosis after an acute shoulder trauma - often found among athletes and people involved in contact sports.This injury occurs five times more frequently in men than in women, with the highest incidence in the 20- to 30-year-old age group. Patients usually complain of pain and.

Superior acromioclavicular ligament. This ligament is a quadrilateral band, covering the superior part of the articulation, and extending between the upper part of the lateral end of the clavicle and the adjoining part of the upper surface of the acromion . It is composed of parallel fibers, which interlace with the aponeuroses of the trapezius.

The trapezoid ligament is quadrilateral. It is attached to the superior aspect of the anterior border of the base of the coracoid process and extends in a posterosuperolateral, roughly straight course to the trapezoid line in the inferior surface of the clavicle (Figs. 1B and 1C).The trapezoid ligament is the primary restraint against posterior clavicular displacement [] and also provides.
