What is the deltoid muscle?
Rehabilitation. The deltoid muscle is the main muscle of the shoulder. It consists of three muscle heads: the anterior deltoid, lateral deltoid, and posterior deltoid. All assist with arm elevation during a process called glenohumeral elevation and play a large role in the movement and overall stability of the shoulder joint and upper arm.
What is the role of the deltoid muscle in surgery?
More specific to the deltoid muscle is its integration within the entire arm, as this plays a role in surgical approaches. Due to the frontal placement of the anterior head of the deltoid, this muscle is an important consideration when surgeons choose an approach which involves access through the front of the arm.
What is the anterior deltoid?
The anterior deltoid is composed of clavicular muscle fibers in accordance with its insertion on the clavicle. The lateral deltoid is composed of acromial muscle fibers to reflect its insertion on the acromion process of the humerus. The posterior deltoid is composed of spinal fibers due to their insertion on spinal processes of the vertebrae.

What is the anatomical variation of the deltoid?
Anatomical Variations. A common anatomical variation of the deltoid includes the presence of separate fascial sheaths and muscle fibers on the posterior deltoid. This may cause medical professionals to mistake the separate muscle fibers of the posterior deltoid for an adjoining muscle, teres minor.
Why is the deltoid muscle mobilized?
Because the deltoid muscle lacks a large tendon of insertion, the tendon of insertion is mobilized together with surrounding periosteum and a rectangular strip of adjacent brachialis. It is mobilized proximally to attain 3 cm of amplitude. Care is taken to avoid injury to axillary nerve branches on its deep surface.
What are the three groups of deltoid muscle?
The deltoid muscle has three distinct groups of fibers. These are grouped into the anterior, lateral, and posterior divisions. The groups arise from the clavicle, acromion, and posterior border of the scapular spine respectively and insert on the deltoid tuberosity of the humerus.

Alternatively, the fascia lata (see Fig. 117.22B ), tibialis anterior tendon, 53 or the central third of the triceps tendon 111 may be used.
How long does a cast last?
A long-arm cast, applied from the upper humerus to just proximal to the wrist with the elbow in 10 degrees of flexion, is worn for 6 weeks. Then the patient begins active extension exercises. To prevent stretching of the newly transferred muscle-tendon unit, however, elbow flexion is increased only 10 degrees per week.
Where is the deltoid muscle located?
Deltoid. The deltoid muscle is easily accessible in the upper third of the arm. The injection is given between the upper and lower portions of the deltoid muscle (Figure 10-5 ), thereby avoiding the radial nerve. The boundaries of the deltoid region form a rectangle.
Where is the active recording electrode placed on the deltoid muscle?
The deltoid muscle is tested with the patient seated, the active recording electrode being placed on the belly of the muscle and the reference electrode on the acromion. The arm is held adducted against the side. Activation is produced by the patient abducting the arm against resistance.
What is the most common injury to the deltoid muscle?
One of the most common injuries to the deltoid muscle is a deltoid strain. Deltoid strain is characterized by sudden and sharp pain where injured, intense soreness and pain when lifting the arm out from the side of the body, and tenderness and swelling caused by (and located at) the deltoid muscle. Last medically reviewed on January 20, 2018.
What muscle is responsible for a person's arm rotation?
The deltoid muscle is responsible for the brunt of all arm rotation and allows a person to keep carried objects at a safer distance from the body. It is also tasked with stopping dislocation and injury to the humerus when carrying heavy loads. One of the most common injuries to the deltoid muscle is a deltoid strain.
Why is the deltoid muscle named after the letter Delta?
The deltoid muscle was named after the Greek letter Delta due to the similar shape they both share. The deltoid muscle is constructed with three main sets of fibers: anterior, middle, and posterior. These fibers are connected by a very thick tendon and are anchored into a V-shaped channel.
How does the posterior fiber of the arm work?
Contraction of the posterior fibers extends and laterally rotates the arm by pulling the humerus toward the spine of the scapula. Extension and lateral rotation moves the arm posteriorly, as in reaching backwards or winding up to throw a ball underhand.
How do the deltoid bands merge?
The bands merge together as they approach the insertion point on the deltoid tuberosity of the humerus. The deltoid has three distinct functions that correspond to the three bands of muscle fibers. Contraction of the anterior fibers flexes and medially rotates the arm by pulling the humerus towards the clavicle.
What is the deltoid shaped like?
It is named after the Greek letter delta, which is shaped like an equilateral triangle. The deltoid is attached by tendons to the skeleton at the clavicle (collarbone), scapula (shoulder blade), and humerus (upper arm bone). The deltoid is widest at the top of the shoulder and narrows to its apex as it travels down the arm.
How does the lateral fiber abduct the arm?
The lateral fibers abduct the arm by pulling the humerus toward the acromion. Abduction of the arm results in the arm moving away from the body, as in reaching out to the side.
Where is the deltoid origin?
The deltoid has three origins: the lateral end of the clavicle, the acromion of the scapula at the top of the shoulder, and the spine of the scapula. Each origin gives rise to its own band of muscle fibers with the anterior band forming at the clavicle, the lateral fibers forming at the acromion, and the posterior fibers forming at the spine ...
