Collarbone fractures are among the most common broken bones in both children and adults. They tend to happen fast, often from a hard fall while skiing or cycling. As a father of five, I understand how alarming it is to watch someone you love go down and refuse to move their arm. If you’ve ever wondered what a fractured collarbone feels like, for most people it’s sharp pain right over the bone, a shoulder that seems to sag, and a strong reluctance to lift the arm. In this post, I’ll explain how a collarbone fracture happens, how it’s diagnosed, when it can heal on its own, and when surgery may come into the conversation.
Key Takeaways
- The collarbone (clavicle) usually breaks from a fall onto the shoulder or an outstretched arm, and the middle third of the bone is where the large majority occur.
- Sharp pain over the collarbone, a sagging shoulder, and a visible bump are three of the most common signs.
- Many collarbone fractures heal well in a sling without surgery, and adults commonly return to normal daily activities within about three months.
- Surgery may be considered when the bone ends are badly displaced, shortened, or pressing against the skin.
Understanding the Collarbone
The collarbone, or clavicle, is the long, slightly S-shaped bone that runs across the top of the chest between the breastbone and the shoulder blade. It acts as a strut that holds the shoulder out to the side so the arm can move freely. Because it sits just under the skin with very little padding, it’s vulnerable to direct blows and falls.
Fractures are described by location. The middle third of the bone, called the midshaft, is where the large majority occur. Fewer happen near the outer end, close to the AC joint at the top of the shoulder, and fractures near the breastbone are uncommon.
What Does a Fractured Collarbone Feel Like?
There’s rarely much doubt that something is wrong. The pain is sharp, sits directly over the collarbone, and gets worse when you try to move the arm.
You may notice:
- A sagging shoulder. With the collarbone no longer holding the shoulder out, the shoulder droops forward and down. Patients frequently support the injured arm against the body with the other hand.
- A bump or deformity. Swelling and bruising are common, and with a displaced fracture, the broken end may push up under the skin.
- Grinding with movement. Some people feel or hear a grinding sensation when they try to raise the arm.
Numbness, tingling, or weakness in the arm or hand, or any trouble breathing, needs emergency evaluation. The collarbone sits close to major blood vessels, nerves, and the top of the lung, so these symptoms may signal a more serious injury.
In young children, the signs can be subtler. A child might simply refuse to use the arm or cry when lifted under the arms.
How Collarbone Fractures Happen
The classic cause is a fall directly onto the shoulder or onto an outstretched hand. In teens and younger adults, bike crashes, football tackles, skateboarding falls, and dirt bike or ATV wrecks lead the list. In older adults, a simple fall at home can be enough to break the collarbone.
How a Collarbone Fracture Is Diagnosed
Diagnosis begins with an exam. I look for deformity, check the skin over the fracture, and test circulation, sensation, and strength in the arm and hand.
X-rays confirm the break and show its location, how far the pieces have moved, and whether the bone has shortened. For more complex fractures, particularly those near either end of the collarbone, a CT scan may help clarify the pattern.
I pay close attention to the skin. If a sharp bone fragment is tenting the skin, meaning pushing it tight from underneath, that fracture needs prompt attention so the skin doesn’t break down.
Healing Without Surgery
Many collarbone fractures, especially those that are minimally displaced, heal well without surgery. For a fracture treated without surgery, my plan generally includes:
- A sling for comfort, typically for the first few weeks
- Ice and over-the-counter pain medication, when appropriate for your health history
- Elbow, wrist, and hand motion early, then gentle shoulder motion as pain allows
- Follow-up X-rays to confirm the bone is healing in an acceptable position
Healing time depends heavily on age. A young child’s collarbone may heal in roughly three to six weeks. In adults, bone healing commonly takes around six to twelve weeks, and most people return to normal daily activities within about three months. Smoking and diabetes can slow the process.
A firm bump commonly forms over the fracture as it heals. That bump is new bone, called callus, and it tends to become less noticeable over time, especially in children.
When Surgery May Be Considered
Surgery isn’t the default for a collarbone fracture, but some breaks may heal better with it. An operation may be considered when:
- The bone ends are widely separated, or the collarbone has shortened significantly
- A bone fragment is pressing against or through the skin, or nearby nerves or blood vessels are involved
- The fracture is near the outer end of the collarbone and unstable
- The bone hasn’t healed after several months, which is called a nonunion
The most common surgical approach uses a plate and screws along the bone to hold the pieces in alignment. Another option places a rod or pin inside the bone.
For active adults with a significantly displaced midshaft fracture, the choice between a sling and surgery is often a shared decision rather than a clear-cut answer. In my view, the right choice depends on the fracture pattern and on what the patient needs the shoulder to do.
What I See in My Patients
In my Newnan and Fayetteville offices, collarbone fractures seem to follow the calendar. Fall brings youth and high school football injuries. Warmer months bring more cycling falls, dirt bike crashes, and the occasional golf cart tumble on the paths around Peachtree City.
The question I hear most from parents is whether the bump will be permanent. A child’s collarbone has a remarkable ability to remodel, and that bump frequently fades over the following months.
With adults, the most common frustration is stiffness. After several weeks of protecting the arm, the shoulder can tighten up, and the last bit of overhead reach can take dedicated therapy to recover. For a lot of my active adult patients, the fracture bothers them less than the time it keeps them out of the gym, the pool, or the golf course.
My Approach to Treating a Collarbone Fracture
My approach starts with the X-ray and the person in front of me. A teenager with a minimally displaced midshaft fracture and a 55-year-old who lifts for a living have very different needs, even when their X-rays look similar.
For nondisplaced or minimally displaced fractures, I recommend a sling and early, gentle motion, with X-rays every few weeks to confirm healing. I’d rather see a patient come out of the sling as soon as comfort allows than keep it on longer than necessary, because a shoulder held still too long may stiffen.
When a fracture is significantly displaced or shortened, I talk through the trade-offs of surgical and nonsurgical care openly. That conversation covers healing rates, the likelihood of a visible bump, and the chance of hardware irritation.
Return to sports in my sports medicine practice is based on healing, not the calendar alone. For contact sports, I want to see solid bone healing on X-ray, full motion, and restored strength before giving the go-ahead. I swam competitively at Indiana University, so I’m especially careful with swimmers and other overhead athletes. Jumping back into full training before the shoulder has regained strength can set up a different problem, such as rotator cuff irritation.
Summary
A collarbone fracture usually comes from a fall onto the shoulder or an outstretched arm. It announces itself with sharp pain over the bone, a sagging shoulder, and trouble lifting the arm. Many fractures heal in a sling, and children heal faster than adults. Surgery may be recommended for badly displaced, shortened, or skin-threatening breaks.
If you or your child has had a fall and now has pain or a new bump along the collarbone, the best next step is an exam and X-ray. That tells us where the break is and how far it has moved. Seek emergency care right away if the skin is broken over the bone, the arm feels numb or cold, or breathing is difficult. To schedule an evaluation, you can request an appointment at my Newnan or Fayetteville office or call (770) 502-2175.
Frequently Asked Questions
How long does a broken collarbone take to heal?
A young child’s collarbone may heal in roughly three to six weeks. In adults, bone healing usually takes around six to twelve weeks, and most people return to normal daily activities within about three months. Contact sports wait until X-rays show solid healing and strength has returned, which can take longer.
Can you move your arm with a broken collarbone?
For a fracture treated without surgery, you can generally move the elbow, wrist, and hand right away. Shoulder motion is painful at first, so gentle shoulder movement starts as pain allows, on the schedule set at your follow-up visits.
Will I have a bump after a broken collarbone?
A bump is common, either from the position of the healed bone or from the new bone that forms during healing. In children, it often fades over the following months. In adults, some bump may remain, but it rarely affects function.
How do I sleep with a broken collarbone?
During the first couple of weeks, some people find it more comfortable to sleep semi-upright, either in a recliner or propped up with pillows. Lying flat or on the injured side tends to increase pain early in healing.
