Separated shoulder A separated shoulder (also known as acromioclavicular separation, AC separation), is a common injury to the acromioclavicular joint. It is a joint dislocation, but it is not called a dislocated shoulder, as that term refers to a glenohumeral joint (shoulder joint) dislocation.

Chromatography This page is also available in Romanian and German. Chromatography is a separation process that involves partitioning a protein (or any other soluble analyte) between an insoluble stationary phase and a mobile phase that passes over its surface. A simple, but complete, chromatography system is shown in the diagram below.

Acromioclavicular (AC) Joint Instability, Subluxation & Dislocation An AC Joint Subluxation is a partial dislocation, meaning that the clavicle goes partially out of joint, with part of the clavicle still touching the acromion. An AC Joint Subluxation looks like a small bump on top of the shoulder.

- Although this is part of the shoulder, a dislocated shoulder and a separated shoulder are completely different. Acromioclavicular separation occurs as a result of a downward force being applied to the superior part of the acromion, either by something striking the top of the acromion or by falling directly on it. The injury is more likely to occur if the shoulder is struck with the hand outstretched.

Acromion Acromion shoulder is the lateral extension of the spine of the scapula. Scapula is the scientific name for the shoulder blade. The spine leads to a ‘head’ and here it bears two processes – the acromion process and the carocoid process.cromion Scapula. Scapula is the scientific name for the shoulder blade. It is a kind of triangular, flat bone lying over the back of the upper ribs. The scapula serves as an attachment for the muscles of the arm, neck, chest and the back. The back of the scapula is divided into unequal portions by a spine.

- Thickening of the acromion and the acromioclavicular joint that occur with age, and the development of osteophytes (spurs) on the underside of the acromion and acromioclavicular joint, are the most common causes of shoulder impingement. Usually, the acromion has a flat inferior or lower surface (Type I acromion).

Toddler Car Seat Buying Guide Convertible Seat or Forward-Facing Seat Convertible car seats are great for babies and toddlers because they can transition with your child as he grows. Install the seat rear-facing as long as possible. It is only safe to install your car seat forward-facing if your child is at least 2 years old or has reached the maximum height or weight capacity of the car seat. If your child meets these requirements already, invest in a forward-facing upright seat.

Shoulder Problems / Acromio-clavicular (AC) Joint Dislocations The acromion is a projection from the scapula (shoulder blade) and is located on the top and front (antero-superior) of the shoulder. It can be felt as a bony tip on the top of the shoulder. The acromion is like a “roof” over the rotator cuff.The acromion serves as the attachment of the deltoid muscle.efinition. Os-acromiale is a loose / mobile acromion of the shoulder which may or may not cause pain. In the most cases the loose acromion may go undetected as it does not lead to any painful symptoms.

Shoulder Joint To further reinforce the shoulder, the four muscles of the rotator cuff extend from the scapula and surround the head of the humerus to both rotate the arm and prevent dislocation. The acromioclavicular joint is formed by an articulation between the lateral end of the clavicle and the acromion process of the scapula.

Shoulder Sprain A sprain that tears ligaments in the shoulder most often occurs at the joint between the acromion and collarbone, called the acromioclavicular joint. This injury sometimes is called a shoulder separation. Less often, a shoulder sprain involves the joint between the breastbone and collarbone, called the sternoclavicular joint.

Approach Considerations If all clavicle fractures are considered together, the vast majority heal with nonoperative management, which includes use of a simple shoulder sling. Studies have found, however, that in cases of specific fracture patterns and locations, not all clavicle fractures behave the same way. The focus of treatment of middle third fractures remains nonoperative, although evidence is mounting, in support of operative treatment for displaced midshaft clavicle fractures.

Acromion In human anatomy, the acromion (from Greek: akros, highest, ōmos, shoulder, plural: acromia) is a bony process on the scapula (shoulder blade).Together with the coracoid process it extends laterally over the shoulder joint.he acromion has four ossification centers called (from tip to base) pre-acromion, meso-acromion, meta-acromion, and basi-acromion. In most cases, the first three fuse at 15–18 years, whereas the base part fuses to the scapular spine at 12 years.
