deltoid tuberosity of humerus

The greater tuberosity is the prominent area of bone at the top of the humerus and is the attachment for the two large, powerful rotator cuff muscles - supraspinatus and infraspinatus. About the middle the anter-laterale surface of humeurs is a rough, triangular elevation, the deltoid tuberosity for the insertion of the Deltoideus; This definition incorporates text from a public domain edition of Gray's Anatomy (20th U From these points of origin, the muscle then travels down the arm and inserts on the deltoid tuberosity of the humerus (long bone of the upper arm). Deltoid Anterior Lateral 3rd of clavicle Deltoid tuberosity Anterior: Flex, AB, H AD, IR Middle Acromion Middle: AB Posterior Spine of scapula Posterior: EXT, AD, H AB, ER Subscapularis Subscpular fossa Lesser tubercle IR (MR) Patients were referred for associated pain or for the incidental radiographic findings. The pain I reported is in the deltoid tuberosity, i.e., where the deltoid inserts into the humerus bone, on the mid-arm, halfway between the biceps and the triceps. a rough elevation about the middle of the lateral side of the shaft of the humerus, providing attachment (insertion) for the deltoid muscle. The distal end of the humerus consists of a condyle divided into two parts. 2015; 473(9):3038-45 (ISSN: 1528-1132) Spross C Prominent deltoid muscle insertions often resembles periostitis and may be mistaken for a lesion. In human anatomy, the deltoid tuberosity is a rough, triangular [1] area on the antero lateral (front-side) surface of the middle of the humerus to which the deltoid muscle attaches. Let’s start layering on some more terms on the humerus. O: Lateral 1/3 of clavicle I: Deltoid tuberosity A: Shoulder abduction, flexion, medial rotation and horizontal adduction Anterior Deltoid O: Acromion process I: Deltoid tuberosity A: Shoulder abduction Middle Deltoid O: Spine of scapula I: Deltoid tuberosity A: Shoulder abduction, extension, hyperextension, lateral rotation, horizontal abduction Posterior Deltoid … The rounded capitulum articulates with the head of the radius.

The deltoid has three distinct functions that correspond to the three bands of muscle fibers. It is injured/fractured in a fall by either landing directly onto the side of your shoulder or landing with your arm outstretched. A spectrum of eccentric bone irregularities were observed in the humeral deltoid tuberosity region of five patients. [2] Contents Variation Development Other animals is where the deltoid muscle connects to the humerus. We found that I've been given a diagnosis of bursitis in the supraspinatus tendon on the shoulder itself, and afterwards of tendonitis in the pectoralis major insertion tendon. All fibres converge toward their insertion on the deltoid tuberosity on the middle of the shaft of the humerus. The deltoid tuberosity is the region on the shaft of the humerus to which the deltoid muscle attaches. The Deltoid tuberosity is where the deltoid muscle connects to the humerus. Identify the The bone described here is the humerus. A bone contains a. olecranon fossa, b. deltoid tuberosity, c. head, and d. medial epicondyle. The deltoid muscle is responsible for moving the arm around the shoulder joint, which is one of the most mobile joints in the entire body. Deltoid tuberosity (of humerus) information including symptoms, causes, diseases, symptoms, treatments, and other medical and health issues. The deltoid muscle originates from the lateral part of the clavicle (collarbone), as well as the spine and acromion process of the scapula (shoulder blade). The deltoid muscle inserts on the deltoid tuberosity. The deltoid muscle is muscle used to move your arm. Dr. Ebraheim’s educational animated video describes the anatomy of the Deltoid muscle.The deltoid muscle begins … Contraction of the anterior fibers flexes and medially rotates the arm by pulling the humerus towards the clavicle. Medical definition of deltoid tuberosity: a rough triangular bump on the outer side of the middle of the humerus that is the site of insertion of the deltoid. Introduction: Deltoid tuberosity (of humerus) Description of Deltoid From these points of origin, the muscle then travels down the arm and inserts on the deltoid tuberosity of the humerus (long bone of the upper arm). On the lateral side of the humeral shaft is a roughened surface where the deltoid muscle attaches.This is known is as the deltoid tuberosity.The following muscles attach to the humerus along its shaft: Anteriorly – coracobrachialis, deltoid, brachialis, brachioradialis. tuberosity an elevation or protuberance. Clin Orthop Relat Res. proximal humerus fracture (PHF), (2) relationship of radiological parameters with bone mineral density (BMD), deltoid tuberosity index (DTI), or severe PHF, and (3) correlation between DTI and BMD. See also Deltoid tubercle (on clavicle) External links lesson1bonesofpostshoulder at The Anatomy Lesson by Wesley Norman - insertion: deltoid tuberosity of the humerus; - action: abduction, horizontal flexion and medial rotation of humerus at shoulder; - nerve supply: axillary, C5, C6; - synergists: medial and posterior deltoid divisions, and View This Abstract Online Deltoid Tuberosity Index: A Simple Radiographic Tool to Assess Local Bone Quality in Proximal Humerus Fractures. The bands merge together as they approach the insertion point on the deltoid tuberosity of the humerus. Humerus: The humerus is the upper arm bone, sometimes called the funny bone because of the similar sound of its name and the word humorous. The deltoid tuberosity index correlated strongly with local BMD measured on pQCT and our study evidence shows that it is a reliable, simple, and applicable tool to assess local bone quality in the proximal humerus. 1.
