- In anatomy, the scapula (plural scapulae or scapulas) or shoulder blade, is the bone that connects the humerus (upper arm bone) with the clavicle (collar bone). Like their connected bones the scapulae are paired, with the scapula on the left side of the body being roughly a mirror image of the right scapula. In early Roman times, people thought the bone resembled a trowel, a small shovel. The shoulder blade is also called omo in Latin medical terminology.

Serratus anterior The scapula is able to move laterally due to the serratus anterior muscle, which is vital for the elevation of the arm. The serratus anterior muscle also allows the upward rotation of the arm, which allows a person to lift items over their head. Back to Thorax.

- Typically, the humerus, or upper arm bone, meets the scapula, or shoulder blade, to form what is classed as a ball and socket joint. This is because the round, ball-shaped head of the humerus fits inside a shallow, socket-shaped cavity in the scapula known as the glenoid cavity. think what they do is they go in and tighten where the arm bone and the glenoid cavity interlock so that the bone doesn't move out of the socket so easily. I think it's an easy procedure, because my friend was all better and doing joint exercises in about a month.

- Diagnosis and Treatment of Snapping Scapula Syndrome. The scapula (shoulder blade) is an amazing anatomical structure. It is suspended over the ribs between the spine and the arm by only two ligaments. There isn't a real joint between the scapula and the trunk. Three layers of muscle and bursae (plural for bursa) support this structure.

Scapula Scapula. The scapula is commonly referred to as the shoulder blade. It connects the humerus bone of the arm to the collarbone. There are only three muscles that are responsible for enabling the movement of the shoulder blade. The trapezius muscle implants into the collarbone. small tendon attaches the levator to the upper area of the shoulder blade. This muscle is responsible for pulling up the scapula, which allows for the shrugging movement of the shoulders.

The shaft is triangular in cross section and roughened where muscles attach.

Scapular Dyskinesis/ SICK Scapula Scapular Dyskinesis/ SICK Scapula. The scapula is the large triangular-shaped bone at the back of your shoulder frequently known as the shoulder blade. Its only attachment to the rest of the skeleton is through the collarbone at the acromioclavicular joint. Therefore, the bone is primarily held in place by the attached and surrounding muscles.

What are the Different Causes of Scapula Pain? The scapula, more commonly known as the shoulder blade, is a flat bone shaped much like a triangle. This bone attaches the arm bone to the bones of the ribs. Pain in this area of the body is quite common and can have several potential causes, the most common being excessive or strenuous physical activity. Scapula pain can also be caused by sleeping position or degenerative diseases such as arthritis.

The Scapula Winging of the Scapula. The serratus anterior muscle originates from ribs 2-8, and attaches the costal face of the scapula, pulling it against the ribcage. The long thoracic nerve innervates the serratus anterior. If this nerve becomes damaged, the scapula protrudes out of the back when pushing with the arm.

Your doctor may want you to start moving your shoulder within the first week after the injury to minimize the risk of shoulder and elbow stiffness.

Anatomy The shoulder joint has three bones: the shoulder blade (scapula), the collarbone (clavicle), and the upper arm bone (humerus). The head of the upper arm bone (humeral head) rests in a shallow socket in the shoulder blade called the glenoid. The head of the upper arm bone is usually much larger than the socket, and a soft fibrous tissue rim called the labrum surrounds the socket to help stabilize the joint.
