A shoulder fracture, or broken bone, can be painful and disruptive, limiting the ability to perform daily activities we often take for granted. Simple tasks like reaching for a cup, getting dressed, or driving a car can become difficult challenges. In this post, we’ll explore what a shoulder fracture is, what causes it, how it is diagnosed, and the various treatment options.

Key Takeaways

• A shoulder fracture is a break in one of the three bones of your shoulder: the clavicle (collarbone), the scapula (shoulder blade), or the proximal humerus (the top of your upper arm bone).
• Common causes include falls, sports injuries, and car accidents. The type and severity of the fracture often depend on the nature of the trauma.
• Symptoms typically include severe pain, swelling, bruising, and an inability to move the arm. A visible deformity may also be present.
• Treatment options range from non-surgical methods, such as wearing a sling and undergoing physical therapy, to surgical procedures like open reduction and internal fixation (ORIF) or shoulder replacement for more severe fractures.

The Anatomy of Your Shoulder

The shoulder is composed of three main bones. The clavicle, or collarbone, connects the shoulder to the chest. The scapula, or shoulder blade, is a large, triangular bone that sits in the upper back. The proximal humerus is the top part of your upper arm bone, which has a ball-like head that fits into a socket in the scapula. 

These bones work together with a network of muscles, tendons, and ligaments. This intricate system provides both mobility and stability. However, the same design that allows for such a wide range of motion also makes the shoulder susceptible to injury, including a shoulder fracture.

What Constitutes a Shoulder Fracture?

A shoulder fracture is simply a medical term for a broken bone in the shoulder. The specific type of shoulder fracture depends on which bone is broken and the nature of the break itself. 

• Clavicle Fractures: These are common, especially among younger individuals and athletes. The collarbone is relatively thin and sits in a vulnerable position, making it prone to breaking from a direct blow or a fall onto the shoulder.
• Proximal Humerus Fractures: These fractures occur at the top of the upper arm bone. They are more common in older adults, often resulting from a fall onto an outstretched arm. 
• Scapula Fractures: A broken shoulder blade is the least common type of shoulder fracture. The scapula is well-protected by the chest and surrounding muscles. A significant amount of force, such as from a high-speed car accident or a major fall, is usually required to fracture this bone. Because of the force involved, scapula fractures are frequently associated with other injuries.

Fractures are also classified by how the bone breaks. A non-displaced fracture means the bone is broken, but the pieces remain in their proper alignment. A displaced fracture occurs when the bone fragments move out of position. In an open fracture, the broken bone pierces the skin. 

What Leads to a Shoulder Fracture?

The causes of a shoulder fracture are often related to some form of trauma. High-impact events are a primary cause. For example, a collision during a contact sport like football or hockey can lead to a clavicle fracture. A fall from a ladder or down a flight of stairs can result in a proximal humerus fracture, especially if you land on your shoulder or try to break the fall with your arm. Motor vehicle accidents can generate enough force to cause any type of shoulder fracture, including the less common scapula fracture.

For older adults, the risk of a shoulder fracture increases due to a combination of factors. Bone density tends to decrease with age, a condition known as osteoporosis, making bones more brittle and susceptible to breaking. A simple ground-level fall, which might only cause a bruise in a younger person, can result in a proximal humerus fracture in an older individual.

Recognizing the Signs and Symptoms

The most prominent symptom of a shoulder fracture is severe pain. This pain is often localized to the site of the break and can be sharp and debilitating. You will likely find it very difficult, if not impossible, to lift or move your arm. 

Swelling and bruising are also common. The area around the shoulder may become visibly swollen within a short time after the injury. Bruising can be extensive, sometimes extending down the arm and onto the chest. You might also notice a deformity or a bump that is not normally present. In some cases, you might hear or feel a grinding or crackling sensation, known as crepitus, when you try to move your shoulder.

How a Shoulder Fracture is Diagnosed

For diagnosis, your doctor will likely begin by asking you about how the injury occurred. They will also perform a careful physical examination of your shoulder. Your doctor will look for signs of swelling, bruising, and deformity. They will gently feel the area to pinpoint the location of the pain and to check for any abnormalities in the bone structure.

While a physical exam can strongly suggest a shoulder fracture, imaging tests may be used to support the diagnosis and to determine the extent of the injury. An X-ray is the most common tool for diagnosing a fracture. It provides images of the bones and can show the location and severity of the break. 

In some situations, more detailed imaging may be needed. A Computed Tomography (CT) scan can provide a more detailed, three-dimensional view of the bones. This can be particularly helpful for complex fractures, such as those involving the shoulder joint itself or when the bone is broken into multiple pieces. A Magnetic Resonance Imaging (MRI) scan is less commonly used for diagnosing fractures, but may be ordered if the doctor suspects that there is also damage to the soft tissues.

Treatment Approaches for a Shoulder Fracture

The treatment for a shoulder fracture depends on several factors. These include the type and severity of the fracture, your age, your overall health, and your activity level. The primary goal of treatment is to allow the bone to heal in the correct position, relieve pain, and restore function to the shoulder.

Non-Surgical Treatment

Many shoulder fractures can be treated successfully without surgery. Conservative treatment typically involves immobilization. Your arm will be placed in a sling or a shoulder immobilizer to keep the bone in the proper position while it heals. This also helps to reduce pain and prevent further injury.

You will likely need to wear the sling for several weeks. During this time, it is important to follow your doctor’s instructions carefully. You may be encouraged to move your fingers, wrist, and elbow to prevent stiffness. Pain medication will be prescribed to help manage your discomfort. Regular follow-up appointments and X-rays may be used to monitor the healing process.

Surgical Treatment

For more severe fractures, surgery may be necessary to realign the bones and ensure proper healing. Surgical intervention is often recommended for displaced fractures, open fractures, or fractures that involve the shoulder joint. The type of surgery will depend on the specific nature of your injury.

One of the most common surgical procedures for a shoulder fracture is open reduction and internal fixation (ORIF). During this procedure, the surgeon makes an incision to access the broken bone. The bone fragments are then repositioned into their normal alignment (reduction). An experienced orthopedic surgeon uses special hardware, such as plates, screws, or pins, to hold the bones in place (internal fixation). 

In cases where the shoulder joint is severely damaged and cannot be repaired, a shoulder replacement (arthroplasty) may be recommended. This is more common in older adults with complex proximal humerus fractures. In many of these cases, a reverse shoulder replacement may be preferred because it relies less on the rotator cuff for function.

Preventing Future Injuries

While it is not always possible to prevent accidents, there are steps you can take to reduce your risk of a shoulder fracture. For older adults, preventing falls is the most important measure. This can include making your home safer by removing tripping hazards, installing handrails on stairs, and ensuring adequate lighting. Regular exercise to improve balance and strength can also help prevent falls.

For athletes, using proper protective equipment and following the rules of the sport can help reduce the risk of injury. It is also important to warm up properly before playing and to use proper technique to avoid unnecessary stress on the shoulder.

Summary

A shoulder fracture can cause significant pain and limit everyday movement, but many fractures heal successfully with proper care. Diagnosis typically involves imaging to determine the severity of the injury, and treatment may include immobilization, physical therapy, or surgery for more complex fractures. With an individualized treatment plan and guided rehabilitation, many patients can regain function and return to daily activities.

Frequently Asked Questions

Will I need surgery for my shoulder fracture?

Not all shoulder fractures require surgery. Many can be treated with immobilization and physical therapy. Surgery is typically reserved for more severe fractures where the bones are out of place, the joint is damaged, or non-surgical treatments fail to provide adequate relief. 

Can I move my arm at all while it is in a sling?

Your doctor will give you specific instructions on what movements are safe. You will likely be encouraged to move your fingers, wrist, and elbow to prevent stiffness. However, you should avoid moving your shoulder until your doctor says it is safe to do so.

Is physical therapy always required?

Physical therapy is commonly recommended to restore range of motion and strength once the bone has healed enough to move safely. The timing and intensity of therapy vary based on the injury and treatment approach. Motion and strength can improve for up to a year or more after some types of shoulder fractures.
