Imaging anatomy fracture of the scapula May. Snapping scapula syndrome usually is a result of abnormal anatomy, abnormal scapulothoracic motion, space-occupying bony or soft-tissue lesions or a combination of these. The scapula bears two marked processes: the acromion and, rather less obvious, the coracoid. Objective: The purpose of this article are to review scapular anatomy and function, describe imaging features of traumatic scapular injury, and discuss the role of diagnostic imaging in clinical decision making after shoulder trauma. the level of the glenohumeral joint on the posterior aspect of the patient (5 cm below the top of the shoulder) central to the medial scapula border. The . Epidemiology. Median Nerve - distal humerus. . 1, Coracoid Process (scapula). FPnotebook.com is a rapid access, point-of-care medical reference for primary care and emergency clinicians.

The most frequently used imaging modalities are radiography (X-ray), computed tomography (CT) and magnetic resonance imaging (MRI).X-ray and CT require the use of ionizing radiation while MRI uses a magnetic . This bone is located posteriorly (on the back half of the body). The scapula serves as the attachment site for 18 muscles, which link it to the thorax, spine, and upper extremity. 9). The main part of the scapula, the body, consists of a somewhat triangular-shaped flat blade, with an inferiorly pointing apex, referred to as the inferior angle as well as lateral and superior angles. The name "scapula" derives from Latin, meaning "trowel" or "small shovel," which it seems to resemble. Nonoperative treatment consists of physical therapy. This definition incorporates text from a public domain edition of Gray's Anatomy (20th U.S. edition of Gray's Anatomy of the . Radial Nerve - radial groove. It is also important to be familiar with imaging pitfalls related to US technique, such as anisotropy. Together with the clavicle, the scapula forms the . Explore. Insertion: Superior part of medial border of scapula. Indications. The scapula is a flat, triangular bone located posterior to the ribcage. In humans they are triangular and lie on the upper back between the levels of the second and eighth ribs. About Coding Info. Scapular fractures are reported to account for approximately 0.5% to 2.4% of all fractures in dogs. Patient position For humeral head. 26 Fat in soft tissue . They hold the head of the humerus in the small and shallow glenoid fossa of the scapula. When autocomplete results are available use up and down arrows to review and enter to select. CT cerebral venography (also known as a CTV head or CT venogram) is a contrast-enhanced examination with an acquisition delay providing an accurate detailed depiction of the cerebral venous system.. NB: This article is intended to outline some general principles of protocol design. The bones visible on a chest X-ray include the clavicles, the ribs, the scapulae, the spine, and the proximal humeri (upper arms). IMAGING IMAIOS Dicom Viewer; e-MRI; . The scapulothoracic joint is located where the shoulder blade (also called the scapula) glides along the chest wall (the thorax). This article will review the relevant anatomy, etiology, clinical evaluation, diagnostic testing, and treatment of scapular winging. Radiographs of the scapula, shoulder joint, and humerus are needed in dogs and cats that present due to: Trauma. The five principal densities seen on plain imaging (see Chapter 1) should be used as reference points to identify anatomical and pathological structures. Ossification Center. Magnetic resonance imaging (MRI) utilizes magnet and radio waves to produce diagnostic images that allow a doctor to visualize the . Snapping scapula syndrome is fairly rare. The scapula is a triangular shaped bone located approximately 5 cm lateral to the thoracic spinous processes and spanning from the second to the seventh ribs [].It is comprised of three borders—superior, axillary (lateral) and vertebral (medial)—and three angles (superomedial, inferomedial, and lateral) [].While the ventral surface of the scapula is typically concave, the osseous . It is essential that the individual performing the US examination has an understanding of pertinent anatomy, such as bone surface anatomy and tendon orientation. Scapula. The shoulder joint is a joint that connects the upper limb to the axial skeleton. The glenohumeral joint is often described as a ball-and-socket joint (5).
