5 Common Shoulder Injuries

5 Common Shoulder Injuries

The shoulder, a complex and highly mobile joint, is susceptible to a variety of injuries. Whether you’re an elite athlete or someone who enjoys occasional recreational activities, understanding common shoulder injuries can be the key to prevention and timely treatment. At Performance Sports Medicine Institute, we believe in empowering our patients with knowledge, so let’s delve into the intricacies of some of these injuries.

The Anatomy of the Shoulder 

The shoulder allows for a wide range of motion. However, its complexity also makes it vulnerable. Before we dive into the common injuries, it’s essential to understand the shoulder’s anatomy briefly. 

Bones of the Shoulder

The shoulder consists of three primary bones: the clavicle (collarbone), the scapula (shoulder blade), and the humerus (upper arm bone). These bones form two main joints: the acromioclavicular joint (where the clavicle meets the scapula) and the glenohumeral joint (where the humerus fits into the scapula).

Ligaments and Tendons

Ligaments are tough bands of tissue that connect bones to other bones. In the shoulder, several ligaments provide stability and limit the joint’s movement. Tendons, on the other hand, connect muscles to bones. The rotator cuff tendons are particularly crucial, as they hold the humerus firmly in the shoulder socket and enable a wide range of movements.


The shoulder muscles play a pivotal role in movement and stability. The deltoid muscle, for instance, covers the shoulder and provides its rounded contour. Beneath it, the rotator cuff – a group of four muscles – works in tandem to stabilize and move the shoulder.


A bursa is a small fluid-filled sac that reduces friction between the bones and surrounding soft tissues. The subacromial bursa, located between the rotator cuff and the acromion (part of the scapula), is particularly significant. It ensures smooth movement of the tendons but can become inflamed, leading to conditions like bursitis.

Common Shoulder Injuries and Their Implications

Shoulder injuries can range from mild to severe, and understanding them can be the first step toward effective management and recovery.

Rotator Cuff Tears

The rotator cuff is a group of muscles and tendons that stabilize the shoulder. Overuse, trauma, or wear and tear can lead to tears. Symptoms often include pain, especially when lifting the arm, and weakness. Conservative treatments like physical therapy or more invasive approaches like surgery can be employed depending on the severity.

Dislocated Shoulder

A dislocated shoulder occurs when the upper arm bone pops out of the socket. It’s intensely painful and often results from trauma. Immediate medical attention is crucial, and the arm must be set back into place. Rehabilitation follows to strengthen the area and prevent future dislocations.

Frozen Shoulder (Adhesive Capsulitis)

Characterized by stiffness and pain in the shoulder joint, frozen shoulder often develops slowly and can worsen over time. The exact cause remains unknown, but it’s more common in people with diabetes or those who keep their shoulder immobilized for a prolonged period. Physical therapy and medications can help restore movement and alleviate pain.

Shoulder Impingement

This injury occurs when the shoulder blades press on the rotator cuff tendons. Repetitive overhead activities, like swimming or painting, can lead to impingement. Symptoms include pain when lifting the arm and a reduced range of motion. Rest, physical therapy, and sometimes surgery are treatment options.

SLAP Tears

SLAP stands for Superior Labrum from Anterior to Posterior. It’s a tear of the ring of cartilage (labrum) surrounding the shoulder socket. Often caused by overhead activities or trauma, SLAP tears can lead to a deep aching sensation in the shoulder. Treatment varies from rest and physical therapy to surgical intervention.

Prevention and Recovery

While some shoulder injuries result from unforeseen accidents, many can be prevented with proper techniques, training, and awareness.

Strengthening Exercises

Regular exercises targeting the shoulder muscles can enhance stability and reduce the risk of injuries. Incorporating resistance bands or light weights can be beneficial.

Proper Technique

Whether you’re playing sports or engaging in daily activities, using the correct technique can minimize strain on the shoulder. Regular training and coaching can be invaluable.

Listen to Your Body

Pain is a signal. If you experience discomfort or pain in your shoulder, it’s essential to rest and seek medical advice. Early intervention can prevent more severe complications.
