Types and Symptoms of Shoulder Dislocations: A Comprehensive Guide to Diagnosis and Treatment

Describe the three type of dislocations seen in the shoulder?

Dislocations occur when the bones on opposite sides of a joint do not line up. Dislocations can involve any of three different joints.● A dislocation of the acromioclavicular joint is called a “separated shoulder.”● A dislocation of the sternoclavicular joint interrupts the connection between the clavicle and the breastbone (sternum)● The glenohumeral joint (the ball and socket joint of the shoulder) can be dislocated toward the front (anteriorly) or toward the back (posteriorly).

The three types of dislocations seen in the shoulder are:

1. Anterior dislocation: This is the most common type of shoulder dislocation, accounting for 95% of all dislocations. In this type, the humeral head is forced out of the front of the glenoid cavity. This can occur due to trauma, such as a fall or direct blow to the shoulder, or non-traumatic events, such as repetitive overhead activities. An anterior dislocation may cause pain and instability in the shoulder.

2. Posterior dislocation: Posterior dislocations are rare and account for only 2-4% of all shoulder dislocations. In this type, the humeral head is forced out of the back of the glenoid cavity. This can occur due to significant force or trauma to the front of the chest or shoulder. A posterior dislocation may cause pain and weakness in the shoulder, as well as difficulty moving the arm.

3. Inferior dislocation: This type of dislocation, also known as luxatio erecta, is the rarest form and accounts for less than 1% of all shoulder dislocations. In this type, the humeral head is forced downward, typically due to significant trauma or a fall from a height. An inferior dislocation may cause severe pain and weakness in the shoulder, and may also result in nerve or blood vessel damage.

In all three types of shoulder dislocations, prompt medical attention is necessary to properly diagnose and treat the injury. Treatment may include immobilization of the affected arm, medications for pain and swelling, and in some cases, surgery to repair any damaged structures in the shoulder.
