Przejdź do treściA clavicle fracture does not automatically mean surgery. Many fractures can be treated successfully without an operation, usually with a sling. The choice depends on the location of the fracture, the degree of displacement and comminution, the condition of the skin, shoulder-girdle stability, neurovascular findings, and the patient’s age and functional needs. In selected displaced fractures, surgery reduces the risk of nonunion, but it does not give every patient a better long-term functional result.
How does a clavicle fracture happen?
The most common mechanism is a direct fall onto the shoulder, for example while cycling, skiing or taking part in contact sport. A clavicle fracture can also occur in a road-traffic injury or after a fall onto an outstretched arm.
The location matters as much as the fact that the bone is broken. Midshaft fractures behave differently from lateral fractures near the acromioclavicular joint, while medial fractures near the sternum are less common and raise a different set of anatomical concerns.
What symptoms are typical?
- pain over the clavicle that increases with arm movement;
- swelling and bruising;
- a palpable step, irregularity or deformity;
- difficulty lifting the arm;
- sometimes a clearly prominent bone fragment beneath the skin.
The appearance of the shoulder alone cannot determine whether surgery is required. Clinical examination and X-rays are central to the decision.
How is a clavicle fracture diagnosed?
Plain X-rays are the first-line imaging test. They usually show the fracture location, displacement and comminution well enough to guide initial management. CT can be useful in selected fractures with more complex anatomy, particularly when standard radiographs do not answer the relevant clinical questions.
Ultrasound does not replace X-ray for routine diagnosis of a clavicle fracture. It may, however, help assess selected associated soft-tissue problems around the shoulder.
When does a clavicle fracture need urgent assessment?
Many isolated clavicle fractures can be reviewed in an urgent or planned orthopaedic pathway depending on the injury. Some findings should not wait.
- An open wound over the fracture or visible bone may indicate an open fracture.
- Marked skin tenting, blanching or skin damage over a sharp fragment can mean that the fragment is threatening to break through the skin.
- Numbness, weakness of the hand, a cold or pale limb, or abnormal pulses require assessment for nerve or vascular injury.
- Shortness of breath, chest pain or a high-energy mechanism requires assessment for chest injury and other associated trauma.
- Major shoulder-girdle deformity or suspicion of an associated scapular fracture may indicate a more unstable injury pattern.
When can treatment be non-operative?
Non-operative treatment is often appropriate when displacement is limited or the overall alignment is acceptable, the skin is not threatened and there is no neurovascular injury.
In the acute phase, a sling is usually used. The American Academy of Orthopaedic Surgeons guideline favours a sling over a figure-of-eight brace for most acute clavicle fractures. The main purpose is pain relief and protection during the early phase of healing.
This does not mean complete immobility for many weeks. Movement of the elbow, wrist and fingers is usually maintained from the outset, while shoulder movement is gradually increased according to pain, fracture stability and the treating clinician’s instructions.
When is surgery more likely to be considered?
Absolute or very strong indications for urgent operative treatment include open fractures, threatened skin, significant neurovascular injury and selected unstable injuries of the shoulder girdle.
Outside those situations, the decision is more individual. Surgery is considered more often in adults with markedly displaced, shortened or comminuted midshaft fractures and in selected unstable fractures of the lateral end. Occupation, sport, arm dominance, patient expectations and the estimated risk of nonunion also matter.
No single X-ray measurement determines the need for surgery on its own. Shortening and displacement are part of the assessment, but they need to be interpreted in the full clinical context.
Does surgery give a better result?
The best available evidence is more nuanced than simply saying that surgery is better. Meta-analyses of randomised trials in displaced midshaft clavicle fractures show that operative treatment reduces the risk of nonunion. It may also provide faster functional improvement during the first weeks.
That functional advantage becomes much smaller over time. A meta-analysis of 10 randomised trials including 1,333 patients found a DASH difference of about 9.4 points at 6 weeks in favour of surgery, but the differences at 3 and 6 months were smaller and no longer clinically meaningful.
A 2026 systematic review of 18 randomised trials including 1,201 adults treated non-operatively for displaced midshaft clavicle fractures found that function generally improved substantially during the first months. Nonunion occurred in about 14%, while approximately 13% later underwent surgery.
The practical conclusion is that surgery can reduce the risk of union-related problems in appropriately selected patients, but it is not necessary for every adult with a displaced fracture.
What are the disadvantages of surgery?
Plate fixation or another form of internal fixation carries the usual operative risks, including infection, wound problems, nerve injury, implant-related symptoms and the possibility of another procedure, for example to remove symptomatic hardware. The benefit of reducing nonunion risk therefore has to be weighed against the risks and burden of surgery itself.
How long does a clavicle fracture take to heal?
Healing takes weeks and varies between patients. Pain often improves before full bony union is achieved, so feeling better does not mean the clavicle is ready for heavy loading or contact sport.
Return to heavy work, strength training or sport with a meaningful risk of falling should be based on several factors together: pain resolution, recovery of movement and strength, and adequate fracture healing. Lighter daily activity is often possible earlier, but progression should remain individual.
When should you seek reassessment during non-operative treatment?
- pain is clearly increasing rather than gradually improving;
- a new deformity appears or the fragments seem to be moving;
- the skin over a fragment becomes increasingly tense or red;
- numbness, weakness, or a change in the colour or temperature of the hand develops;
- marked tenderness and lack of healing progress persist after many weeks;
- general symptoms or wound problems develop after operative treatment.
Key points for an orthopaedic surgeon
- Many clavicle fractures can be treated without surgery.
- X-ray is the main imaging test.
- When non-operative care is chosen, a sling is generally preferred to a figure-of-eight brace.
- Surgery is considered more strongly for open fractures, threatened skin, neurovascular injury, instability and selected markedly displaced fractures.
- In adults with displaced midshaft fractures, surgery reduces nonunion risk, but long-term functional results often converge with non-operative treatment.
- The decision should not be based on one radiographic measurement alone.
