A Closer Look at Your Shoulder's Anatomy (And What Can Go Wrong)

A Closer Look at Your Shoulder's Anatomy (And What Can Go Wrong)

The shoulder is a complex and versatile joint, providing a wide range of motion that allows you to perform everyday tasks and athletic activities. However, this flexibility comes with its own set of challenges, making the shoulder susceptible to injuries and disorders. 

If you’re dealing with shoulder pain, limited shoulder mobility, or other symptoms of a shoulder problem, have it evaluated right away. 

Board-certified orthopedic surgeon Matthew Pifer, MD, evaluates, diagnoses, and treats shoulder conditions, providing effective solutions to restore shoulder function and eliminate pain.

Let’s dive into some comprehensive information about the shoulder’s anatomy and common problems that can occur. 

Shoulder anatomy overview

The shoulder joint is made up of three main bones: the upper arm bone(humerus), shoulder blade (scapula), and collarbone (clavicle). 

These bones come together to form two primary joints: the glenohumeral joint, which connects the humerus and scapula, and the acromioclavicular joint, which connects the scapula and clavicle. 

The glenohumeral joint is a ball-and-socket joint that allows for a wide range of motion, making it one of the most mobile joints in your body.

Surrounding these bones are a network of muscles, tendons, and ligaments that provide stability and support. 

The rotator cuff, a group of four muscles and their tendons, plays a crucial role in keeping the humerus's head securely within the scapula's shallow socket. 

Additionally, the labrum — a ring of cartilage around the socket — helps deepen the joint and increase stability.

Common shoulder problems

Due to its complex structure and extensive use, the shoulder is prone to various issues that can affect its function and cause discomfort. Here are some common shoulder problems:

Rotator cuff tears

Rotator cuff tears are common, especially in athletes and other active individuals. The rotator cuff is vital for shoulder stability and movement. Tears can occur due to injury, overuse, or degenerative changes, which can cause pain, weakness, and a limited range of motion.

Shoulder impingement

Athletes who engage in sports that involve repetitive overhead movements, such as baseball, football, and tennis, are prone to shoulder impingement, also known as rotator cuff tendinitis. This occurs when the rotator cuff tendons are squeezed between the shoulder bones.

Dislocation

A shoulder dislocation can affect anyone. It happens when the head of the humerus is forced out of its socket. Sudden force to the shoulder from a fall, direct blow, twisting, or motor vehicle accident can cause the shoulder to dislocate. Additionally, athletes who participate in contact sports, such as football, are at a higher risk of shoulder dislocation. 

Labral tears

Labral tears are another common shoulder issue. The labrum is a type of cartilage that plays a role in keeping the shoulder in place. If the labrum tears, it’s common to experience a clicking or catching sensation when moving the shoulder, in addition to pain and discomfort.  

Arthritis

While not as common as hip and knee osteoarthritis, shoulder osteoarthritis is vulnerable to wear-and-tear. It is more common after the age of 50.

Taking action for shoulder health

Many shoulder issues can be resolved with conservative treatment. However, for serious issues, such as advanced shoulder osteoarthritis or complete rotator cuff tears, surgery is often necessary to repair the damaged tissue and restore proper shoulder function. 

Dr. Pifer specializes in minimally invasive arthroscopic surgery, which uses a small camera and special instruments to examine and repair joints. 

Reducing pain and restoring shoulder function is our top priority. Dr. Pifer also offers regenerative medicine, including platelet-rich plasma therapy and stem cell therapy, to help people recover from shoulder problems. 

These therapies stimulate and accelerate healing and are beneficial for those recovering from surgery, an injury, or chronic issues such as arthritis.

Shoulder issues can happen even under the best circumstances. Contact us today to schedule a consultation and get on the path to shoulder recovery. Let us help you stay active and enjoy a full range of motion.
