When you break your clavicle, the fracture pattern determines whether your shoulder will heal with full strength or develop permanent weakness. The clavicle (collarbone) connects your shoulder blade to your breastbone. It acts as a strut that holds your arm away from your body and allows overhead movement. When this bone breaks, the decision between conservative treatment (non-surgical healing with support) and clavicle fracture surgery depends on fracture characteristics, displacement severity, and your functional requirements.
Clavicle fractures occur frequently in the middle third of the bone, where it’s thinnest and lacks muscular protection. Falls onto an outstretched hand, direct impacts to the shoulder, and sporting collisions account for most injuries. The fracture pattern, whether the bone ends remain aligned or remain significantly separated, determines the initial treatment approach and influences long-term outcomes.
Orthopaedic surgeons evaluate these injuries based on bone displacement, fracture shortening, skin tenting (when bone pushes against skin from inside), and your activity level.
Anatomy and Fracture Classification
The clavicle divides into three zones for classification purposes. The middle third sustains the majority of fractures due to its S-shaped curve and its minimal soft-tissue coverage. The lateral (outer) third connects to the shoulder through ligaments (strong bands of tissue that connect bones), making fractures here potentially unstable. The medial (inner) third rarely breaks but sits near vital structures, including major blood vessels.
Fracture patterns include:
- Simple two-part breaks
- Comminuted (multiple fragment) injuries
- Those with butterfly fragments (small bone pieces that split off from the main break)
Displacement describes how far the bone ends have separated. Shortening measures overlap between fragments. Significant shortening correlates with altered shoulder mechanics and potential strength deficits.
The surrounding soft tissues matter significantly. Skin tenting occurs when a sharp bone fragment protrudes through the skin from the inside, risking skin breakdown if left untreated. Open fractures (in which bone penetrates the skin) require urgent surgical intervention regardless of other factors.
Initial Assessment and Imaging
Clinical examination reveals the typical deformity. The outer shoulder drops forward and downward whilst the inner fragment remains elevated by the sternocleidomastoid muscle (a large neck muscle). Swelling and bruising develop rapidly. Your surgeon checks sensation in the arm and hand, assesses blood flow, and listens for breathing sounds to rule out associated lung injury.
Standard X-rays (radiographic imaging of bones) in two planes confirm the diagnosis and reveal fracture characteristics. The AP (front-to-back) view shows displacement. The angled view demonstrates shortening. CT scans (detailed cross-sectional imaging) add value when fracture lines extend towards joints, when planning complex reconstructions, or when standard X-rays don’t clearly show the injury pattern.
Documentation of fracture shortening proves particularly important. Measuring the difference between the injured and uninjured clavicle lengths helps predict biomechanical outcomes (how well the shoulder will function after healing). Significant shortening alters scapular (shoulder blade) positioning, potentially reducing shoulder strength and endurance for overhead activities.
Conservative Treatment Approach
Non-operative management (healing without surgery) suits many clavicle fractures, particularly those with minimal displacement and shortening. A simple sling provides comfort and allows the arm to rest whilst the bone heals. Figure-of-eight bandages, once standard treatment, have fallen out of favour due to discomfort and lack of proven benefit over slings.
đź’ˇ Did You Know?
The clavicle is one of the first bones to begin forming during foetal development and one of the last to complete growth, with the medial growth plate (the area where bone grows) not fusing until the mid-twenties.
Healing progresses through predictable phases:
- Initial inflammatory response (the body’s natural healing reaction involving swelling and immune cell activity) occurs first
- Soft callus formation (early bone repair tissue) develops around weeks two to three
- This gradually mineralises (hardens with calcium deposits) into hard callus
- Remodelling (reshaping of bone) continues for months afterwards
Clinical healing—when the fracture site no longer hurts with gentle stress—typically occurs between six and twelve weeks.
Activity modification during healing requires balance. Complete immobilisation causes shoulder stiffness and muscle wasting. Excessive movement risks fracture displacement. Gentle pendulum exercises (simple arm swinging movements that use gravity rather than muscle force) begin within the first week. These progress to an active range of motion as healing advances. Return to sports and heavy lifting is delayed until X-rays confirm a solid union (complete bone healing) and strength testing shows adequate recovery.
Indications for Surgical Intervention
Specific fracture characteristics favour operative treatment:
- Displacement exceeding one bone width
- Significant shortening
- Comminution with multiple fragments
When the displaced bone threatens skin integrity through tenting, surgery prevents wound complications.
Open fractures mandate surgical treatment to clean the wound and stabilise the bone. Associated injuries—including floating shoulder (combined clavicle and scapular neck fractures), vascular damage (injury to blood vessels), or brachial plexus nerve involvement (damage to the nerve network controlling arm movement and sensation)—require operative intervention. Polytrauma patients (those with multiple severe injuries) may benefit from fracture fixation to facilitate mobilisation and rehabilitation.
Functional demands influence decision-making. Athletes requiring overhead power, manual labourers, and those whose livelihood depends on upper-extremity function may consider surgical treatment to restore strength. The potential for faster rehabilitation and more predictable outcomes appeals to those unable to accommodate lengthy conservative treatment courses.
Your surgeon weighs fracture characteristics against your individual circumstances, presenting options with their respective benefits and risks.
Surgical Techniques
Plate fixation represents a commonly performed surgical approach. Through an incision along the clavicle, the surgeon realigns the fracture fragments and holds them in place with a contoured metal plate and screws. Modern anatomically-shaped plates match the clavicle’s S-curve, reducing prominence beneath the thin overlying skin.
Superior plating (placing the plate on top of the clavicle) offers mechanical advantages but potentially more noticeable hardware. Anteroinferior plating (positioning the plate on the front-bottom surface) reduces prominence at the cost of slightly more challenging surgical exposure: surgeon experience and fracture pattern guide technique selection.
Intramedullary fixation uses a rod or nail inserted through the bone’s central canal (the hollow channel inside the bone). This approach requires smaller incisions and may produce less hardware prominence. However, it provides less rotational control and is primarily suited to simple fracture patterns. Complex or comminuted fractures generally require plate fixation for adequate stability.
⚠️ Important Note
All surgical approaches carry risks, including infection, hardware irritation, nerve injury, and non-union. Your surgeon will discuss specific risks based on your fracture pattern and chosen technique, tailored to your individual circumstances.
Lateral Clavicle Fractures
Fractures of the outer clavicle near the acromioclavicular joint (where the collarbone meets the shoulder blade) present unique challenges. The coracoclavicular ligaments—strong bands connecting the clavicle to the coracoid process of the shoulder blade—determine stability. When these ligaments remain intact, conservative treatment succeeds reliably.
Displaced lateral fractures with torn coracoclavicular ligaments behave like AC joint separations. The inner fragment rides upwards whilst the outer fragment drops with the arm. These unstable injuries may benefit from surgical stabilisation. Techniques include hook plates (specialised plates with a curved end), coracoclavicular fixation (reattaching torn ligaments), or combinations thereof.
Hook plates curve around the acromion (the bony roof of the shoulder), providing reduction and stability whilst ligaments heal. These require routine removal after healing, typically at three to four months, due to potential rotator cuff irritation (discomfort to the shoulder muscles and tendons) from the hook component. Alternative techniques, such as sutures (strong surgical thread) or synthetic ligament reconstruction, may avoid this second procedure.
Post-Operative Rehabilitation
Early post-operative care focuses on wound healing and pain management. A sling provides comfort and protection for the first few weeks. Gentle pendulum exercises begin immediately, preventing shoulder stiffness whilst protecting the repair.
Progressive rehabilitation advances through phases based on healing milestones:
- The passive and active-assisted range of motion (exercises where someone else moves your arm, or you use your other arm to help) begins first
- Active exercises (movements you perform using your own muscle strength) follow as healing progresses
- Strengthening begins once X-rays show adequate callus formation, typically around six to eight weeks post-surgery
Return to activity follows a graduated protocol. Light daily activities resume early, whilst lifting restrictions persist until the union confirms. Sports participation, particularly in contact sports, should wait until complete healing, restoration of strength, and completion of sport-specific training. Return to unrestricted activity typically occurs between three and six months post-surgery, depending on fracture severity and healing progress.
Potential Complications
Non-union—failure of the bone to heal—occurs in both operative and non-operative treatment. Risk factors include:
- Smoking
- Displaced fractures
- Significant comminution
- Inadequate immobilisation (insufficient support or rest during healing)
Non-union causes persistent pain and weakness. It typically requires surgical intervention with bone grafting (adding bone tissue to promote healing) and plate fixation.
Hardware-related complications include prominence (feeling the plate beneath the skin), irritation, and infection. The clavicle’s subcutaneous position (location just beneath the skin with minimal covering tissue) means plates remain palpable (able to be felt) in most patients. Symptomatic hardware prompts removal after fracture healing, typically performed as a day surgery procedure.
Nerve injury, particularly to small sensory branches (nerves responsible for skin sensation) crossing the surgical field, causes numbness around the incision. This typically improves over months but may persist permanently in some cases. Motor nerve injury (damage to nerves controlling muscle movement) remains rare with careful surgical technique.
âś… Quick Tip
Smoking significantly impairs bone healing. Cessation before and after injury can improve union rates for both conservative and surgical treatment.
Comparing Outcomes
For minimally displaced fractures, both approaches produce results, making non-operative treatment a logical choice given surgical risks. For significantly displaced or shortened fractures, surgery demonstrates lower non-union rates and faster return to activity.
Shoulder strength and endurance matter for overhead athletes and manual workers. Studies measuring isokinetic strength (muscle force measured at constant speed during testing) show potential deficits with significantly shortened healed fractures. For those with modest physical requirements, these differences may prove clinically insignificant.
Patient satisfaction surveys reveal ratings with both approaches when treatment matches fracture characteristics. Satisfaction drops when complications occur or when expectations aren’t met. Clear pre-treatment discussions about timelines, restrictions, and potential outcomes can improve satisfaction regardless of the treatment pathway.
Factors Guiding Your Decision
Fracture characteristics form the foundation of treatment recommendations—simple, minimally displaced middle-third fractures with modest shortening fare well with slings and time. Complex, shortened, or skin-threatening fractures may benefit from surgical stabilisation.
Your circumstances matter equally—occupation, sporting ambitions, hand dominance, and ability to accommodate activity restrictions all factor into decision-making. A construction worker may choose surgery to expedite return to work. A retired individual might prefer avoiding operative risks.
Age influences but doesn’t determine treatment. Younger patients heal reliably and may prioritise biomechanical restoration (restoring standard shoulder mechanics and strength). Older patients with lower demands may accept a slight shortening in exchange for avoiding surgery. Neither extreme of age mandates a particular approach. Your doctor can provide personalised advice based on your specific risk factors, healing capacity, and functional needs.

Commonly Asked Questions
How long does a clavicle fracture take to heal?
Clavicle fractures typically achieve clinical union (when the bone is stable enough for everyday activities) between six and twelve weeks, though the timeline varies from person to person. Complete remodelling continues for months. Surgically treated fractures often demonstrate earlier radiographic healing (visible bone healing on X-rays) and faster return to activity. The biological healing process takes a similar time regardless of treatment method.
Will I need the plate removed after surgery?
Routine plate removal isn’t necessary if the hardware is asymptomatic. However, prominent or irritating hardware can be removed after fracture healing, typically starting six months after fracture. Hook plates used for lateral clavicle fractures require planned removal at three to four months to prevent rotator cuff problems.
Can I drive with a clavicle fracture?
Driving requires comfortable control of the steering wheel and the ability to react quickly. Most patients refrain from driving for four to six weeks, resuming when pain allows safe vehicle control. Insurance implications and legal requirements vary—confirm coverage before returning to driving.
What’s the risk of the fracture not healing?
Non-union rates depend on fracture characteristics and treatment. Minimally displaced fractures treated conservatively heal reliably. Significantly displaced fractures carry a higher non-union risk with conservative treatment, which surgical fixation can reduce. Smoking substantially increases the risk of nonunion with either approach.
When can I return to sports after a clavicle fracture?
Return to sport follows fracture healing, strength restoration, and sport-specific conditioning, though individual recovery timelines vary. Non-contact activities may resume after six to eight weeks, provided adequate healing has occurred. Contact sports and activities with fall risk typically wait three to six months, depending on fracture severity and treatment method. Your doctor can provide personalised recommendations based on your individual healing progress and the demands of your particular sport.
Next Steps
Minimally displaced fractures respond well to conservative care with a sling and time. Significantly displaced, shortened, or comminuted fractures often benefit from surgical stabilisation to restore strength and reduce the risk of non-union. Smoking cessation improves healing outcomes regardless of treatment choice.
If you’re experiencing shoulder pain, visible deformity, or limited arm movement following a fall or direct shoulder impact, consult with an orthopaedic surgeon for fracture evaluation and treatment planning.
