Ventricles, meninges and blood vessels of the brain, how to learn the anatomy of the clavicle while playing games, Swelling, bruising and tenderness over the fractured area, Sagging of the shoulder in an anterior and inferior direction, Bones of the thorax (cadaveric dissection) - Prof. Carlos Suárez-Quian. Coraco-clavicular Ligaments (CCL): These two ligaments (trapezoid and conoid ligaments) attach the clavicle coracoid process of the scapula. There are five main ligaments within the shoulder complex. This ligament has two separate parts name for their shape. The clavicle (also collarbone, Latin: clavicula) is a paired long bone extending between the sternum and the scapula. This type of articulation is also known as a ‘double plane joint’ – where two joint cavities are separated by a layer of articular cartilage. Lee et al. The clavicle is an elongated, S-shaped bone that rests horizontally at the sternum across the upper part of the ribcage, and the acromial end of the scapula. The anterior aspect of the right clavicle....First of all, you have to find the lateral and medial end. The clavicle is located at the top of the thoracic wall, just below the neck and to the sides of the sternum.

Reviewer: This is useful information, as the specific location of pain around body structures helps doctors and other health care providers to figure out what the cause of the patient’s pain is. Blood supply Suprascapular and thoracoaromial arteries Nerve supply Lateral pectoral and axillary nerve Subcutaneous lateral supraclavicular nerve. The anterior lamina courses superolaterally, while the posterior fibers are directed superomedially, forming an inverted cone or cruciate shape. The tip is palpable below the outer end of the distal clavicle, through the anterior fibers of deltoid. Andrew Lim 10-5 ). The lateral end of the clavicle articulates with the acromion of the scapula at the acromioclavicular joint. In Experiment 2 (seven shoulders) the order was 1) the superior acromioclavicular ligament, 2) removal of 5 mm of the distal clavicle, and 3) the inferior acromioclavicular ligament. Register now It does not properly belong to the acromioclavicular joint articulation, but is usually described with it, since it forms a most efficient means of retaining the clavicle in contact with the acromion. All rights reserved. However the joint enables a variety of limited movements of the arm, including: Like the acromioclavicular joint, the sternoclavicular joint is surrounded by an articular cartilage capsule, but with a fibrocartilage articular disk inside that creates a clavicular and a sternal synovial cavity. The joint is also reinforced by two accessory ligaments: Looking for a new way to learn and revise? Watch Queue Queue Read more. found that the IC ligament was the “most readily identified of the SC-associated joint ligaments as a discrete ligament between the two clavicle … The area surrounding the joint gives attachment to the fibrous joint capsule. The acromial facet can be seen at the far posterior edge of the acromial end. • The pectoral girdle is made up of two clavicles and two scapulae which are the anchors that attach the “appendicular” skeleton to the “axial” skeleton. Clavicle fractures can also arise during childbirth, when complications occur as the neonate passes through the birth canal. The medial (sternal end) is thicker and rounder than the lateral one (acromial end). These ligaments are very strong and it requires a lot of force to tear the acromio-clavicular ligaments. At its lateral end it articulates with the acromion, a process of the scapula (shoulder blade), at the acromioclavicular joint. This structure gives attachment to the following: 1. coracobrachialis 2. short head of biceps 3. pectoralis minor muscles 4. coracoclavicular ligaments. The acromion-clavicular ligament and coracoclavicular ligament support the acromion-clavicular joint. What is its main … Last reviewed: October 29, 2020 The next steps in treatment or work-up can then … 1. 2020 Most distal clavicle fractures are the result of a fall onto the distal clavicle or a direct blow to it. The medial end also gives attachment to the following structures: The shaft (or diaphysis, or body) refers to the middle part of any long bone. – The orientation of the clavicle can be distinguished by its ends: a broad, flat acromial end (referred to as the lateral third); and a round pyramidal-like sternal end (referred to as the medial two-thirds). Kenhub. Ligaments in the shoulder connect your humerus to your shoulder blade (also called the scapula). Due to the clavicle’s structure, there are only two planar diarthrosis articulations that can be found. The Young Orthopod 11,759 views Acromial end of clavicle . Alternatively, falls can trigger a clavicle fracture, such as falling directly on one’s shoulder, or falling with an outstretched arm. Coracoclavicular ligaments repair; Neer 2 lateral clavicle fractures; Clavicle Hook plate . Injuries of the clavicle seriously compromise everyday activities. Anterior borde r- is concave anteriorly and provides attachment to deltoid muscle . The acromion-clavicular ligament and coracoclavicular ligament support the acromion-clavicular joint. The lateral end of the clavicle has landmarks that serve as the attachment sites for the coracoclavicular ligament: The coracoclavicular ligament is a very strong ligament that connects the clavicle with the coracoid process of the scapula. Such an intervention is quite effective. Operation with rupture of clavicle ligament. Copyright © Each end has unique bony landmarks, depending whether the superior or inferior surface of the bone is viewed. Les ligaments coraco-claviculaires sont des éléments très forts et résistants qui, bien que ne se liant pas directement à l'acromion, confèrent une stabilité à l'articulation acromio-claviculaire. The first is the acromioclavicular joint, which is formed by the acromial end of the clavicle and the acromion of the scapula respectively. The shaft of the clavicle serves as an origin site for several muscles, including the deltoid, trapezius, subclavius, pectoralis major, and sternohyoid. The costoclavicular ligament … This article will discuss the anatomy of the clavicle. Find out how to learn the anatomy of the clavicle while playing games! The acromial or lateral end of the clavicle has an oval facet for articulation with the acromion of the scapula to form the acromioclavicular joint. This bone is an important part of the skeletal system since it plays an essential role in everyday functional movement, serving as the connection between the axial skeleton and the pectoral girdle. The Coracoclavicular Ligament serves to connect the clavicle with the coracoid process of the scapula. The clavicle is an S-shaped bone that is anchored by strong ligamentous attachments on both its medial and lateral ends. Martin Lalama Introduction. There is only a single “true” anatomical joint between the pectoral girdle and the axial skeleton, and that is the sternoclavicular joint. Learning anatomy is a massive undertaking, and we're here to help you pass with flying colours. This synovial joint is important as it anchors the clavicle and scapula to the axial skeleton. The inferior aspect of the medial end is marked by a rough oval depression for the attachment of the costoclavicular ligament. It does not properly belong to the acromioclavicular (AC) joint articulation, but is usually described with it, since it forms a efficient means of retaining the clavicle in contact with the acromion.It consists of two fasciculi, the trapezoid ligament in front, and the conoid ligament behind. Displaced lateral one third clavicle fracture carries the risk of nonunion requiring fixation which is agreeable by many authors [1-3]. origin: knuckle of the coracoid process of the scapula; runs upward, forming an inverted cone as it widely attaches to the undersurface of the clavicle (around the conoid tubercle); trapezoid ligament The IC ligament connects the superomedial aspect of each clavicle with the capsular ligaments and the upper part of the sternum ( Fig. The distance to the center of the trapezoid tuberosity was 25.4 +/- 3.7 mm in males and 22.9 +/- 3.7 mm in females (P =.04). Surgical treatment for distal clavicle fracture with coracoclavicular ligament disruption. These ligaments are very strong and it requires a lot of force to tear the acromio-clavicular ligaments. The coracoclavicular ligament serves to connect the clavicle with the coracoid process of the scapula.. Located directly above the first rib, it acts as a strut to keep the scapula in place so that the arm can hang freely. They are responsible for binding together the collarbone and shoulder blade. The clavicle has two ligaments involving the shoulder that help with stabilizing it to nearby bony structures: The acromioclavicular ligament and the coracoclavicular ligament both stabilize the clavicle to the shoulder blade. The sterno-clavicular joint is oriented somewhat posterior, lateral, and upward. Read more. Author information: (1)Department of Orthopaedic Surgery, Chang Gung Memorial Hospital, Taoyuan, Taiwan. Two muscles are attached to the lateral third of the clavicle: Three muscles are attached to the medial third of the clavicle: Fractures are common pathologies that occur in the clavicle, usually resulting from injury or trauma. Instead of your doctor simply saying that “the patient knee hurts”, he or she can say that “the patient’s knee hurts anterolaterally”. Clavicle Anatomy Made Easy | ANIMATED | Attachments | Side determination | Clinical anatomy -NEET PG - Duration: 5:34. These ligaments are located near the shoulder at the outside end of the collarbone. Sternoclavicular joint ligaments stabilize the joint on its anterior and posterior surfaces. The sterno-clavicular joint is a shallow, relatively incongruous joint supported by a strong ligamentous complex. Whereas the AC ligament works as the primary restraint to horizontal stability, the CC ligaments act as the primary restraint to vertical stability. The collarbone is a large doubly curved long bone that connects the arm to the trunk of the body. It contains an intra-articular disk or meniscus that helps provide congruity and stability. The sternal or medial end of the clavicle has a large triangular facet for articulation with the clavicular notch on the manubrium of the sternum. Posteriorly, th… Ligaments usually are found near joints and perform a variety of functions, depending on the movements in the joint. Patients with distal clavicle fractures typically present with shoulder pain. The other is the sternoclavicular joint, which is formed by the sternal end of the clavicle and the manubrium of the sternum. Conoid and trapezoid ligaments anchor the clavicle to the coracoid process, suspending the free limb and scapula from the clavicle Movements There is limited movement at this joint; the clavicle rotates on the acromion. When facing forward, its medial part is convex, while its lateral aspect is concave. An operation is performed when the clavicle ligament is ruptured only in especially serious cases. Kim Bengochea, Regis University, Denver, Author: There are no muscular or ligamentous attachments on the middle section of the clavicle, and this supports the fact that most … In this case, he will not put pressure on the acromion. From infancy, the articular cartilage starts off as hyaline cartilage, but soon develops into fibrocartilage (at the scapula acromion and the clavicle acromial end at ages 17 and 24, respectively).The acromioclavicular ligament forms a strong connection between the clavicle and the scapula acromion, which restricts movement about the clavicle at its acromial end. The clavicle acts as a strut that keeps the scapula in place so that the upper limb can hang freely. The main functions of the clavicle include: The clavicle can be divided into three parts: a sternal (medial) end, a shaft, and an acromial (lateral) end. Distal clavicle excision can perhaps be safely performed in the context of coracoclavicular ligament reconstruction without subjecting the graft to detrimental in situ force. It enables slight gliding movement about the shoulder region. Interestingly, the clavicle is the only long bone that lies horizontally in the human body.
