Clavicle Fracture (Broken Collarbone)
What is Clavicle fracture?
A clavicle fracture, commonly called a broken collarbone, is a break in the long bone that runs horizontally across the top of the chest, connecting the sternum (breastbone) to the scapula (shoulder blade). The clavicle stabilizes the shoulder girdle and protects important neurovascular structures that run underneath it. Most fractures occur in the middle third of the bone, but they can also involve the inner (medial) or outer (lateral) third.
While many clavicle fractures heal without surgery, the injury can be painful, limit arm motion, and in rare cases damage surrounding nerves or blood vessels. Prompt evaluation and appropriate management are essential to prevent complications such as malunion, nonâunion, or shoulder dysfunction.
Common Causes
Clavicle fractures are usually the result of direct or indirect trauma. Below are the most frequent mechanisms:
- Falls onto an outstretched hand (FOOSH): The force travels up the arm to the shoulder.
- Direct blow to the shoulder: Sports collisions, bicycle accidents, or being struck by an object.
- Motor vehicle collisions: Seatâbelt injuries or impact with the steering wheel.
- Contact sports: Football, rugby, hockey, and wrestling often involve highâenergy impacts.
- Falls from height: Landing on the shoulder or chest while descending stairs or ladders.
- Childhood playground injuries: Falling off monkey bars or swings.
- Birth trauma: Rarely, a difficult delivery can fracture a newbornâs clavicle.
- Severe sneezing or coughing (rare): In patients with osteoporosis or metabolic bone disease.
- Sports equipment mishaps: E.g., a ski pole or golf club striking the clavicle.
- Violent physical altercations: Punches or kicks to the shoulder region.
Associated Symptoms
Besides the obvious pain at the fracture site, patients often experience:
- Visible bump or deformity over the midâclavicle.
- Swelling and bruising (hematoma) that may spread to the neck or chest.
- Difficulty moving the arm across the body (adduction) or lifting it overhead.
- Pain that worsens with deep breaths, coughing, or sneezing.
- Tenderness to light touch or pressure.
- Radiating pain to the shoulder blade or upper back.
- Occasional numbness or tingling if the fracture compresses the brachial plexus.
- Limited range of motion due to pain and muscle guarding.
When to See a Doctor
Although some minor clavicle cracks can be managed at home, you should schedule a medical evaluation promptly if you notice any of the following:
- Severe, worsening pain that does not improve with overâtheâcounter pain relievers.
- Visible bone fragments protruding through the skin (open fracture).
- Significant swelling or bruising that spreads rapidly.
- Difficulty breathing, swallowing, or speaking.
- Sudden, intense numbness or weakness in the arm or hand.
- Obvious misalignment of the shoulder or a âstepâoffâ deformity.
- Persistent pain after 2â3 weeks without improvement.
These signs may indicate complications that require urgent or surgical treatment.
Diagnosis
Healthcare providers use a combination of history, physical examination, and imaging studies to confirm a clavicle fracture.
Clinical Evaluation
- History: Details of the injury, mechanism, and any prior shoulder problems.
- Inspection: Look for swelling, bruising, and deformity.
- Palpation: Tenderness over the clavicle, especially at the fracture site.
- Neurovascular check: Assess sensation, strength, pulse, and capillary refill in the arm.
Imaging
- Plain Xâray: Firstâline test; includes anteroposterior (AP) and sometimes a 30âdegree cephalic tilt view.
- CT scan: Provides detailed bone anatomy, useful for complex, comminuted, or displaced fractures.
- Ultrasound: Occasionally used in children to limit radiation exposure.
- MRI: Reserved for evaluating associated softâtissue injuries (e.g., ligament tears) or when a occult fracture is suspected.
Classification
Clavicle fractures are often categorized by location:
- Midâshaft (middle third): Most common; may be displaced.
- Lateral third (distal): Near the acromioclavicular joint; may involve the coracoclavicular ligaments.
- Medial third (proximal): Rare, can be associated with thoracic injuries.
Treatment Options
The goal of treatment is to relieve pain, promote proper bone healing, and restore full shoulder function.
NonâSurgical (Conservative) Management
- Immobilization: A sling or figureâ8 brace for 1â2 weeks to limit shoulder motion while allowing some clavicular movement.
- Pain control: Acetaminophen, ibuprofen, or naproxen as directed; prescription NSAIDs or short courses of opioids for severe pain.
- Cold therapy: Ice packs 15â20 minutes several times daily during the first 48â72âŻhours to reduce swelling.
- Physical therapy: Initiated after pain subsides (usually 1â2âŻweeks). Focus on gentle pendulum exercises, then progressive rangeâofâmotion and strengthening drills.
- Activity modification: Avoid lifting >5âŻlb, overhead activities, and contact sports for 6â8âŻweeks.
Surgical (Operative) Management
Surgery is considered when the fracture is:
- Highly displaced (>2âŻcm) or angulated (>30°).
- Open (bone protruding through skin).
- Comminuted with multiple fragments.
- Associated with neurovascular injury.
- In a professional athlete or someone who needs early return to highâlevel activity.
Procedures typically involve internal fixation with a plate and screws or, less commonly, intramedullary pins. Postâoperative care includes a brief period of immobilization followed by guided rehabilitation. Studies show surgical fixation can lead to faster union and lower nonâunion rates in selected patients (Mayo Clinic, 2023).
Home Care & SelfâManagement
- Keep the sling on as prescribed; gently adjust it to avoid skin irritation.
- Maintain good posture to reduce strain on the healing clavicle.
- Perform prescribed breathing exercises to prevent lung complications.
- Stay hydrated and maintain a balanced diet rich in calcium and vitaminâŻD to support bone healing.
Prevention Tips
While not all clavicle fractures are preventable, you can reduce risk by adopting these habits:
- Wear protective gear: Shoulder pads in contact sports and helmets with neck support for cycling or motorcycling.
- Strengthen shoulder girdle muscles: Regular resistance training improves stability.
- Practice safe fall techniques: Learn to roll and protect the shoulder when tripping.
- Use seat belts correctly: Ensure the shoulder strap lies across the chest, not the neck.
- Maintain bone health: Adequate calcium, vitaminâŻD, weightâbearing exercise, and routine screening for osteoporosis in atârisk adults.
- Childproof environments: Install safety nets, supervise playground equipment, and pad hard surfaces.
- Warmâup before activity: Dynamic stretches increase flexibility and prepare the clavicleâsupporting muscles.
Emergency Warning Signs
If any of the following occur, seek immediate medical attention (go to an emergency department or call 911):
- Sudden, severe shortness of breath or difficulty breathing.
- Fainting, dizziness, or a rapid drop in blood pressure.
- Visible bone fragments protruding through the skin (open fracture).
- Intense, spreading numbness or loss of movement in the arm or hand.
- Rapidly expanding swelling or bruising that compresses the neck or throat.
- Signs of infection at the fracture siteâredness, warmth, fever, or pus.
Key Takeâaways
A clavicle fracture is a common injury, especially among active individuals and children. Early recognition, appropriate imaging, and a tailored treatment planâwhether conservative or surgicalâlead to excellent outcomes for most patients. However, persistent pain, neurovascular changes, or the redâflag symptoms listed above warrant prompt professional evaluation.
