The shoulder is the most mobile joint in the body, but that versatility comes at a cost. It also makes the shoulder prone to injury. Falling onto the shoulder, or onto an outstretched arm, is one of the commonest ways to injure it. So what are the main shoulder injuries from falling and when does shoulder pain after a fall need urgent attention?

What happens when you fall on your shoulder?

A fall transmits a sudden, high force through the shoulder. Depending on how you land, that force is absorbed by different structures. The result is one of a handful of common injuries: a broken collarbone, a break at the top of the arm bone, a dislocated shoulder, a sprain of the joint on top of the shoulder, or a tear of the rotator cuff. Other injuries include damage to nerves supplying the shoulder or trauma triggering a frozen shoulder.

We manage most injuries without surgery, but some involve complications that require prompt care. The sections below walk through each. There’s a clear list of warning signs further down.

When shoulder pain after a fall needs urgent attention

Seek emergency care after a fall if you have:

an obvious deformity or a bone that looks out of place (fracture)

numbness, tingling, a cold or pale hand, or weakness in the arm (possible nerve or blood-vessel injury)

severe pain with an inability to move the arm at all

a shoulder that looks “empty” at the front or is visibly dislocated

any difficulty breathing or chest pain (a fractured collarbone rarely injures the structures beneath it).

These are uncommon, but they change what needs to happen next — so when in doubt, get assessed the same day.

Broken collarbone (clavicle fracture)

The collarbone is one of the most commonly broken bones, and a fall onto the shoulder is the usual cause. Most breaks happen in the middle third of the bone.

Generally, people fracture their collarbone from a fall onto the outside of the shoulder or outstretched hand.

You’ll usually have pain, swelling, and tenderness over the collarbone. Sometimes there is a visible bump or deformity. The good news is that the great majority heal well without surgery. We manage these injuries with a simple arm sling for comfort, early elbow movement, and later shoulder exercises.

A few breaks do need specialist review:

Outer end (lateral) fractures near the AC joint – these injuries have a higher chance of non-union. Also, fractures extending to the joint can lead to early osteoarthritis of the AC joint.
Inner end (medial) fractures near the breastbone
Any with significant displacement of the fracture

Very rarely, a collarbone fracture injures the structures beneath it, such as the blood vessels or the brachial plexus—which is why breathing difficulty, numbness, and a cold hand are red flags.

Broken top of the arm bone (proximal humerus fracture)

A fracture of the proximal humerus — the top of the arm bone — most often affects older adults after a fall onto an outstretched arm, though a direct blow can cause it in younger people. There’s usually diffuse pain, swelling, and bruising, making it hard to pinpoint a single tender spot.

Around 85% of these fractures are undisplaced and stable. They are treated without surgery — a sling for comfort, then early, graded movement (starting with gentle pendulum exercises) to avoid a stiff shoulder. Displaced fractures, fracture-dislocations, and any with nerve or blood-vessel involvement need surgical review. Occasionally the axillary nerve is bruised in this injury, which is worth checking for.

Another cause of shoulder pain after a fall is a fracture of the greater tuberosity of the humerus. People with this injury complain of intense pain and inability to lift their arm upwards. Treatment is generally conservative with a sling for a few weeks followed by rehab. Fractures with displacement greater than 2 mm require fixation within 2 weeks.

Dislocated shoulder (glenohumeral dislocation)

The shoulder is the most commonly dislocated major joint, and about 90% of dislocations are anterior — the ball comes forward out of the socket. In younger people, it’s usually caused by sport or trauma. In older people, this injury occurs from a fall.

A dislocated shoulder is intensely painful. The arm is usually held still and cradled, and there may be a visible fullness at the front with an “empty” hollow beneath the point of the shoulder. It needs prompt reduction (putting the joint back) — ideally after an X-ray to check for an associated fracture.

Posterior shoulder dislocations occur classically during a seizure. However, it may happen after a fall onto an outstretched hand with the arm internally rotated, forcing the ball of the shoulder backwards.

An important issue after a first dislocation is the high rate of recurrence, especially in people under 30 — and in young, active people, early surgical stabilisation can give a better outcome than rehabilitation alone. In older patients, a shoulder dislocation often leads to other injuries such as fractures, rotator cuff tears and nerve damage; see our guide to shoulder dislocation and nerve damage.

AC joint sprain (shoulder separation)

The acromioclavicular (AC) joint sits on the top of the shoulder, where the collarbone meets the shoulder blade. The classic injury is a direct fall onto the point of the shoulder, which sprains or tears the ligaments that hold the joint together. We often call it a “shoulder separation”.

We grade AC injuries by severity (the Rockwood classification, types I to VI):

Types I and II — the milder sprains, with tenderness over the AC joint and little or no visible deformity. Treated without surgery: a short period in a sling, ice, anti-inflammatories, then range-of-motion and strengthening exercises.

Type III — a fuller disruption with a visible bump from the raised collarbone. Management is debated, so these are best assessed individually. For elite athletes, we consider surgery, but for amateur weekend warriors, we consider rehab.

Types IV–VI — severe, obviously deformed injuries that need urgent referral and usually surgery.

For persistent pain from an AC joint injury, an ultrasound-guided AC joint injection can help settle symptoms once a fracture has been excluded.

Rotator cuff tear

The rotator cuff is the group of four muscles and tendons that stabilise and move the shoulder. A significant fall — or a dislocation — can tear it, particularly in older people whose tendons are already worn. (In younger athletes, a traumatic cuff tear is less common, and is usually a high-force injury.)

A cuff tear typically causes pain and weakness, worse with overhead activity and when lifting the arm out to the side or rotating it. The diagnosis is made based on the history and examination, with ultrasound or MRI to confirm and grade the tear. Ultrasound is particularly useful here, as it shows the tendons dynamically, in real time.

Treatment is individualised. Many tears are managed conservatively — a short period of relative rest, ice, anti-inflammatories, and a supervised physiotherapy programme, sometimes with a subacromial injection. But a young, active person with an acute, full-thickness tear and significant weakness should be assessed promptly. Early surgical repair may give the best result.

How are shoulder injuries from falling diagnosed?

Assessment starts with the story of the fall and a careful examination — including, importantly, checking the arm’s nerves and circulation. Imaging then confirms the injury:

X-ray — the first-line test for a suspected fracture or dislocation. A proper shoulder series (rather than just rotation views) is best for spotting associated injuries.

Ultrasound — excellent for the soft tissues, especially the rotator cuff and the AC joint, and it allows a dynamic, real-time assessment.

MRI — the standard for detailed soft-tissue assessment. We also use it to diagnose rotator cuff and cartilage tears or injuries not fully explained by other imaging.

How are they treated?

We manage most shoulder injuries from falls without surgery — a sling for comfort and pain relief, followed by early, graded movement and strengthening, usually guided by a physiotherapist. Early movement matters, because the shoulder stiffens quickly if it’s kept still. People may develop frozen shoulder after a fall.

Surgery is reserved for specific situations:

displaced or unstable fractures,
higher grade AC injuries
recurrent dislocations (especially in younger, active people)
significant rotator cuff tears in the right patient.

The key is an accurate diagnosis, so the small number of injuries that genuinely need surgery aren’t missed — and the majority that don’t are rehabilitated properly.

Frequently asked questions about shoulder pain after a fall

How do I know if my shoulder is broken or just bruised after a fall?

You often can’t tell for certain without an X-ray, which is exactly why a significant fall with ongoing pain should be assessed. Warning signs that point to a fracture or dislocation include an obvious deformity, severe pain with an inability to move the arm, marked swelling and bruising, or any numbness, tingling, or a cold, pale hand. A bruise settles over days; a fracture or dislocation doesn’t, and needs proper assessment. Examples of fractures include proximal humeral fractures and greater tuberosity fractures.

Should I go to A&E after falling on my shoulder?

Go to A&E (or urgent care) if you have an obvious deformity, can’t move the arm, have severe or worsening pain, or have any numbness, weakness, a cold or pale hand, or breathing difficulty. These suggest a fracture, dislocation, or nerve or blood vessel injury that requires prompt treatment. For milder, persistent pain, an assessment with a sports medicine doctor — including in-clinic ultrasound — is a sensible next step.

How long does shoulder pain after a fall take to settle?

It depends entirely on the injury. A minor AC sprain or a bruise may settle within 1 to 3 weeks. A fracture, dislocation, or rotator cuff tear takes considerably longer to recover from and requires structured rehabilitation. If your shoulder pain isn’t steadily improving over a couple of weeks, it’s worth getting a sports doctor to assess you.

I fell weeks ago, and my shoulder still hurts — what could it be?

Persistent pain weeks after a fall suggests the injury was more than a bruise — commonly a rotator cuff tear, an AC joint injury, or an undisplaced fracture that wasn’t picked up at the time. A missed dislocation is less likely but possible. An assessment with examination and imaging (ultrasound or MRI) will clarify what was injured and guide treatment. Lingering, unexplained shoulder pain after a fall shouldn’t just be pushed through.

Can a fall cause long-term shoulder problems?

It can, if a significant injury is missed or under-treated — for example, a rotator cuff tear left unrepaired in the right patient, a recurrent dislocation, or an AC injury that stays painful. Nerve damage can lead to muscle weakness, wasting and loss of strength, which can be permanent if not diagnosed early enough. This is why an accurate early diagnosis matters: most injuries respond well with the right care, but the few that require more than a sling are best identified early rather than late.

Final word from Sport Doctor London about shoulder injuries from falling

Shoulder injuries from falling are diverse— a broken collarbone, a fracture at the top of the arm bone, a dislocation, an AC joint sprain, or a rotator cuff tear. We manage most injuries without surgery. However, a few have important complications, so knowing the red flags — deformity, an inability to move the arm, or any numbness, weakness, or a cold hand — is what matters most. If shoulder pain after a fall is severe or simply isn’t settling, it’s worth getting properly assessed.

If you have shoulder pain after a fall, Dr Masci can assess you in London, including in-clinic ultrasound and the appropriate imaging. Contact the team here or call +44 (0) 203 488 0350.
