A break at the outer end of the collarbone, near the top of the shoulder, is usually caused by a fall and most often heals without an operation. Whether it stays put depends less on the bone itself than on the ligaments that hold the collarbone down to the shoulder blade. Even when the bone never fully knits, many people still end up with a shoulder that works almost normally, which is why surgery is a choice rather than a given for many.
Symptoms and How It Is Diagnosed
An ordinary fall from standing caused 57% of these breaks in a large UK group, and a harder fall caused 29%.1PubMed Central. Distal third clavicle fractures The average patient was 57, so this is a common injury of older adults after a trip, not only of athletes.2PubMed Central. Distal third clavicle fractures
The pain is sharp and sits right at the top point of the shoulder. It gets worse when you lift the arm, and holding the arm against your body eases it. Swelling and bruising appear, and the bruising may spread down the arm over a few days. If the broken end has moved, you may see or feel a bump or step under the skin.
Doctors confirm the break with standard shoulder X-rays.3Orthobullets. Clavicle Fractures – Distal They often add a tilted X-ray, taken with the beam angled about 15 degrees upward to show the joint at the top of the shoulder clearly.4Orthobullets. Clavicle Fractures – Distal5The Upper Limb Clinic. Understanding and Treating Distal Clavicle Fractures
A shoulder separation, which can look like this break, hurts in the same spot. It is torn ligaments with no broken bone, and an X-ray is needed to tell the two apart, which is why imaging matters.
Some signs call for urgent care: skin that is tented or broken over the bone, numbness, tingling or a cold hand, or trouble breathing after a high-energy fall.
Stable Versus Unstable Breaks
Two ligaments run down from the collarbone to a hook-shaped part of the shoulder blade and keep the collarbone from riding up.6PubMed Central. Restoring Horizontal Stability of the Acromioclavicular Joint: Open Acromioclavicular Ligament Reconstruction and Repair With Semitendinosus Allograft Smaller ligaments around the joint at the top of the shoulder keep it from sliding forward and back, and they help with upward stability too.7PubMed Central.

The Role of the Acromioclavicular Ligament in Acromioclavicular Joint Stability: A Cadaveric Biomechanical Study
Doctors often describe these breaks by Neer type, a grading by where the break lies relative to those ligaments.9PubMed Central. Classifications in Brief: The Modified Neer Classification for Distal-third Clavicle Fractures. Type I breaks lie beyond intact ligaments and don’t shift, and they make up about half of cases.10PubMed Central. Classifications in Brief: The Modified Neer Classification for Distal-third Clavicle Fractures.11PubMed Central. Distal third clavicle fractures Type II breaks cut off the ligament support so the inner bone lifts away, and they make up about a third of cases.12PubMed Central. Classifications in Brief: The Modified Neer Classification for Distal-third Clavicle Fractures.13PubMed Central. Distal third clavicle fractures Type III breaks run into the shoulder-top joint itself.14PubMed Central. Classifications in Brief: The Modified Neer Classification for Distal-third Clavicle Fractures. An unstable type II is the one where surgery comes up.
In a type I break the strong ligaments stay attached to the main collarbone, so the broken tip is still held in line. In a type II break they stay with the small outer piece, and the main bone loses its anchor.
Ligament damage drives the risk because the forces on the bone pull in opposite directions. Muscles of the neck pull the inner bone up, and the weight of the arm pulls the outer piece down. Without ligaments to resist, a gap opens, and a gap resists healing.
In your X-ray report, look for words like displaced, nondisplaced, or Neer II. Displaced means the pieces have moved apart.
Healing Without Surgery
Nearly 9 in 10 of these breaks are treated without surgery.15PubMed Central. Distal third clavicle fractures A simple sling for about two weeks controls pain while gentle assisted shoulder movement begins.16PubMed Central. Treatment Strategies for Distal Clavicle Fractures: A Narrative Review
The sling takes the weight of the arm off the break, since that weight is what drags the outer piece downward. Wear it as your clinician directs, and ask whether you can remove it for gentle exercises. Many people sleep better propped semi-upright, in a recliner or against several pillows, because lying flat lets the shoulder drop back and pull on the break. Keep your elbow, wrist and fingers moving through the day to prevent stiffness and swelling in the rest of the arm. Expect a visible bump to remain.
Early movement usually means pendulum swings: you lean forward, let the arm hang loose, and let it swing in small circles using body motion rather than muscle effort. Someone else may also move your arm gently. The aim is to prevent a stiff shoulder, not to build strength yet. Lifting, pushing up from a chair with the injured arm, and reaching overhead stay off limits until the clinician says the break is healing.
For unstable type II breaks treated in a sling, the bone fails to knit in about 3 in 10 cases, with studies ranging from 28% to 44%.17PubMed. Outcomes, Union Rate, and Complications After Operative and Nonoperative Treatments of Neer Type II Distal Clavicle Fractures: A Systematic Review and Meta-analysis of 2284 Patients18PubMed Central. Current Concepts for Classification and Treatment of Distal Clavicle Fractures Yet only about half of these unhealed bones cause symptoms.19PubMed Central. Treatment Strategies for Distal Clavicle Fractures: A Narrative Review Across studies, shoulder function a year on is about the same with or without surgery.20PubMed. Operative Versus Nonoperative Treatment of Acute Displaced Distal Clavicle Fractures: A Multicenter Randomized Controlled Trial
Trouble does happen. Problems after sling treatment include a painful unhealed bone in about 15%, joint arthritis in 12% and pinching in the shoulder in 8%.21PubMed Central. Treatment Strategies for Distal Clavicle Fractures: A Narrative Review In one trial, 1 in 5 people treated in a sling later had an operation.22PubMed. Operative Versus Nonoperative Treatment of Acute Displaced Distal Clavicle Fractures: A Multicenter Randomized Controlled Trial A painful bone that hasn’t knitted can still be fixed later, sometimes with a bone graft.23PubMed Central. Current Concepts for Classification and Treatment of Distal Clavicle Fractures24Elsevier / Injury. Treatment of distal clavicle nonunion with and without bone grafting
Pain at the break months later, clicking or grinding with overhead use, or weakness lifting the arm are signs the unhealed bone is a problem. Report them rather than waiting.
When Surgery Is Offered and What It Involves
In a trial of displaced breaks, 95% healed within a year after surgery compared with 64% in a sling.25PubMed. Operative Versus Nonoperative Treatment of Acute Displaced Distal Clavicle Fractures: A Multicenter Randomized Controlled Trial Shoulder function at a year was the same in both groups, though.26PubMed. Operative Versus Nonoperative Treatment of Acute Displaced Distal Clavicle Fractures: A Multicenter Randomized Controlled Trial Surgery therefore makes most sense for active people or manual workers, very displaced breaks, or anyone who puts a high priority on the bone healing.
A sling tends to suit people less active with that arm, those whose break has moved only a little, and anyone for whom anesthesia carries extra risk. Both choices are reasonable for many people, so your own priorities, such as avoiding a second operation versus avoiding any operation, carry real weight.
A locking plate screws along the top of the collarbone to hold the pieces.27PubMed Central. Comparison of the efficacy of a distal clavicular locking plate versus a clavicular hook plate in the treatment of unstable distal clavicle fractures and a systematic literature review A hook plate has a hook that tucks under the shoulder-top bone to hold the collarbone down.28PubMed. A prospective randomized controlled trial comparing plating augmented with coracoclavicular fixation and hook plate fixation of displaced distal-third clavicle fractures Both heal at similar rates.29PubMed Central.

Another method threads a strong cord between small metal buttons to tie the collarbone back down, sometimes through keyhole surgery.33PubMed Central. A Technique of Distal Clavicle Fracture Fixation Using The Tightrope Procedure It uses less hardware, healed every break in one series, and rarely needed a second operation.34PubMed Central. Distal Clavicle Fracture Repair: Clinical Outcomes of a Surgical Technique Utilizing a Combination of Cortical Button Fixation and Coracoclavicular Ligament Reconstruction In comparisons, healing was about 95% with smaller cuts and less bleeding than a hook plate.35PubMed Central.

The operation is usually done under general anesthesia, often with same-day discharge. The surgeon makes an incision along the top of the shoulder, and you wear a sling afterward for comfort. Stitches are checked about two weeks later.
Useful questions for your surgeon: which method, and why for my break? Will the hardware need to come out? How soon can I return to work? What happens if I choose a sling instead?
Risks After Surgery
Plates sit just under the skin, and about 30% of people ask to have them removed.36Orthobullets. Clavicle Fractures – Distal Infection affects about 5%.37Orthobullets. Clavicle Fractures – Distal Still, almost all breaks heal after surgery, about 99% in one series.38PubMed. Complications after surgical treatment of distal clavicle fractures
Hook plates cause the most trouble. About 6 in 10 people with a hook plate needed it removed for irritation, compared with 1 in 6 with a contoured plate.39PubMed. Complications after surgical treatment of distal clavicle fractures The reason is that the hook can wear into the shoulder-top bone in about 6 in 10 patients.40PubMed Central. What is the optimal implant removal timing following hook plate fixation in distal clavicle fractures: a retrospective analysis from subacromial osteolysis cases41PubMed Central. Fixing Cho Type IIC Distal Clavicle Fractures with Hook Plates Leads to a High Incidence of Subacromial Osteolysis: A Retrospective Study and Literature Review The risk rises sharply if the plate stays in longer than about 5 months.42PubMed Central. What is the optimal implant removal timing following hook plate fixation in distal clavicle fractures: a retrospective analysis from subacromial osteolysis cases It can also cause pinching and tendon damage.43Journal of Orthopaedic Reports. Acromion osteolysis and fracture following hook plate fixation after acute acromioclavicular joint dislocation in an elderly patient: A case report If you have a hook plate, plan its removal.
Because plates lie just under the skin on top of the shoulder, irritation often shows up where something presses, such as a bag strap, a bra strap or a seatbelt. Some people notice an aching lump over the plate, or tenderness that wasn’t there early in recovery. With a hook plate, pain when lifting the arm overhead can mean the hook is rubbing the bone or tendons beneath it, and it is worth reporting.
Removal is a shorter, simpler operation, usually through the same scar and done once the bone has healed. Expect a few days of soreness afterward.
Recovery Timeline and Getting Back to Work and Sport
After plate surgery, most people report only mild arm problems by 2 months and near-normal by 6 months.44PubMed Central. Outcome of distal end clavicle fractures treated with locking plates About 8 in 10 reached good or excellent shoulder function.45PubMed Central. Outcome of distal end clavicle fractures treated with locking plates
In the first two weeks you are mostly in a sling with gentle movement, and the aim is comfort rather than progress. From about two to six weeks you can usually handle light daily tasks near the body, but lifting stays off limits. From about six to twelve weeks, strengthening begins as the bone firms up, and your physiotherapist adds load gradually.
Desk work is often possible within 1-2 weeks, but manual work waits for healing. Drive only once you can steer safely without the sling.
From about three months onward, heavier work and sport become realistic if the X-ray and exam show the bone has healed. Time alone is not the test. Pain-free full movement and near-normal strength compared with the other side are better signs of readiness than a calendar date.
Among elite athletes with collarbone breaks, return took about 65 days after surgery and about 98 days without.46PubMed Central. Return to elite-level sport after clavicle fractures In teenage athletes the sling group returned faster, about 61 days compared with 100.47PubMed. Factors influencing time to return to sport following clavicular fractures in adolescent athletes Either path usually means 2 to 3 months away from contact sport, the last thing to return.
Long-Term Outlook and Arthritis
Arthritis of the shoulder-top joint was found in 94% of previously broken collarbones and 90% of the other, uninjured side.48PubMed. Fracture of the clavicle does not affect arthritis of the ipsilateral acromioclavicular joint compared with the contralateral side: An osteological study The break itself added little, and where it was or how much it shortened made no difference.49PubMed. Fracture of the clavicle does not affect arthritis of the ipsilateral acromioclavicular joint compared with the contralateral side: An osteological study Later aches at the top of the shoulder are often age-related rather than from the old break.
A visible bump is common and harmless. Weather-related or overhead aches can persist. See a doctor if pain returns after months of comfort.
Distal Clavicle Fractures in Children
In children the injury often happens through the growth plate and can look like a joint separation.50Orthobullets. Distal Clavicle Physeal Fractures The growth plate there stays open until after 19, and a thick bone sleeve stays attached to the ligaments, so the bone remodels.51PubMed Central. Distal clavicle fractures in children Sling or figure-of-eight treatment therefore gives good function even with large displacement, and surgery is rarely needed.52PubMed Central. Distal clavicle fractures in children
A child often has pain at the top of the shoulder, reluctance to use the arm, and a visible bump or swelling after a fall or a collision in sport. An X-ray helps your doctor see what is actually injured. If the skin looks tented over the bone, or the hand is numb or cold, seek urgent care.
Most children wear a sling for comfort for a few weeks while the injury settles, and keep their elbow, wrist and fingers moving through the day. The lump shrinks over months as the bone remodels. Return to play comes once the child is pain-free with full movement.
