The shoulder is the most mobile joint in the body and the most frequently injured. The same range of movement that makes the shoulder so functional in everyday life also makes it more susceptible to injury than most other joints.

Falls, sports accidents, road collisions, and direct trauma can all cause significant shoulder damage including dislocations, fractures, ligament injuries, and rotator cuff tears among them. In some cases, the nerves and blood vessels that run close to the joint are also affected, which is why a shoulder injury that looks simple on the surface can carry complications that are not immediately visible. At CARE Hospitals, emergency specialists evaluate shoulder injuries rapidly, with advanced imaging, effective pain relief, and timely treatment aimed at protecting joint function and giving each patient the best possible foundation for recovery.

What is a Shoulder Injury?

The shoulder joint accounts for roughly 50% of all joint dislocations seen in emergency departments. The acromioclavicular joint (AC joint - where the collarbone meets the shoulder blade) separates or fractures in falls. The clavicle (collarbone) is the most commonly fractured shoulder bone. The rotator cuff (supraspinatus, infraspinatus, subscapularis, and teres minor) tears from acute trauma or overuse. The axillary nerve (wrapping around the upper arm bone) is at risk in dislocations and fractures, producing outer arm numbness and deltoid weakness.

Common Causes of Shoulder Injury

Mechanism determines which structures are at risk.

• Fall on an outstretched hand: A common cause of shoulder injuries, which can lead to collarbone fractures, shoulder fractures, AC joint injuries and proximal humeral fractures
• Fall directly on the shoulder: Can cause shoulder separation, collarbone fractures or damage to the surrounding ligaments
• Forced external rotation: Sudden twisting pushes the arm outward while raised; the humeral head (ball) pops in front of the shoulder socket
• Sports collision: Rugby and football cause dislocation and rotator cuff injury; repetitive overhead activities in sports like cricket, tennis or swimming may lead to rotator cuff and labral injuries
• Road traffic accident: Dashboard or airbag impact causes high-energy fractures and dislocations often with neurovascular injury
• Spontaneous rotator cuff tear: In patients over 50, lifting a bag can tear a degenerate tendon.

Signs and Symptoms of Shoulder Injury

Common symptoms are:

• Immediate severe shoulder pain that is worsened by any arm movement
• Visible deformity like a squared-off flat shoulder suggests anterior dislocation; a step at the collarbone suggests AC joint separation
• Inability to move the arm
• Swelling and bruising 
• Numbness in the outer arm 
• The patient cannot raise the arm sideways
• Pain at the top of the shoulder indicates AC joint injury, especially with a palpable step above the joint.

First Aid for Shoulder Injury (Before Reaching Hospital)

Correct first aid prevents secondary injury and prepares for safe transfer:

• Do not attempt to relocate the shoulder: Without imaging and sedation, amateur reduction risks humeral head fracture, entrapped biceps tendon & axillary nerve or artery damage. Leave reduction to trained clinical staff after X-ray.
• Immobilise in the position of comfort: Support in the position of least pain, usually with the elbow bent at 90 degrees and the forearm across the body in a sling. Do not force the arm into a position it resists.
• Apply ice: Wrap ice in a cloth and apply for up to 20 minutes. Cold reduces swelling and numbs pain. Do not apply directly to the skin.
• Check the hand: If fingers are pale, cold, or numb, go to the hospital immediately.
• Nothing by mouth: No food or drink as procedural sedation or surgery may be needed.
• Go to emergency care: All significant shoulder injuries need X-ray before any manipulation.

When to Seek Emergency Care for Shoulder Injury

These need a same-day emergency assessment:

• Visible deformity after a fall or collision - possible dislocation or fracture
• Inability to move the arm at all after injury
• Numbness or tingling in the arm after a shoulder injury 
• Pale, cold, or numb hand 
• High-energy mechanism including road accident, fall from height, or significant sports collision
• Suspected clavicle fracture in a child
• Visible skin tenting (bone pushing from beneath) or an open wound at the shoulder.

Emergency Treatment at the Hospital for Shoulder Injury

Assessment moves from neurovascular check to imaging to reduction or surgical referral:

• Neurovascular assessment: Doctors evaluate the wrist pulse, outer deltoid sensation (axillary nerve territory) and grip strength before and after any manipulation.
• Imaging evaluation: X-rays are performed to confirm dislocations, fractures, and joint alignment. CT scans or MRI assess bone, cartilage, labral or rotator cuff injuries in greater detail.
• Pain control and sedation: Intravenous pain medicines or sedation reduce pain and relax muscles making joint reduction significantly safer.
• Closed reduction: With the patient settled the orthopaedic team manually guides the shoulder back into position using established techniques. Post reduction X-ray confirms position.
• Fracture management: Doctors treat:
• Clavicle fractures: Sling for three to six weeks; surgery for significantly displaced or open fractures. 
• Proximal humeral fractures: Non-displaced fractures managed conservatively but three and four-part fractures need fixation or humeral head replacement.
• Immobilisation: The reduced shoulder is placed in a sling for two to four weeks and abduction slings are used for specific fracture patterns.

Conclusion

Shoulder injury spans a self-limiting AC joint sprain to axillary artery compression - a vascular emergency. At CARE Hospitals, the emergency team performs neurovascular assessment before any manipulation, images before any reduction, uses procedural sedation to make reduction safe, and arranges specialist review when surgery is indicated.

FAQs

1. What should I do immediately after a shoulder injury?

Support the arm in a sling, apply ice wrapped in cloth, check the hand for pallor or numbness, and go to an emergency department - do not attempt to relocate the shoulder.

2. Is a shoulder dislocation more serious than a fracture?

Both are serious. Some anterior dislocations involve axillary nerve injury, and axillary artery damage threatens the limb.

3. Can I move a dislocated shoulder?

The arm is fixed by pain and spasm so forcing movement risks humeral head fracture or neurovascular damage; support it still and let clinical staff manage reduction after X-ray.

4. How is a shoulder injury treated?

• Dislocation: X-ray, sedation, closed reduction and post-reduction X-ray
• Clavicle fracture: sling for most cases and surgery for displaced fractures
• Rotator cuff tear: physiotherapy for most, surgical repair for full-thickness tears in active patients.

5. Is it safe to pop a dislocated shoulder back in place?

No - without imaging and sedation, amateur reduction risks humeral head fracture, entrapped biceps tendon, and nerve or artery damage; all reductions need X-ray and sedation first.

6. How long does recovery from a shoulder injury take?

Recovery takes:

• Glenohumeral dislocation: two to four weeks in a sling, six to twelve weeks of physiotherapy
• Clavicle fracture: three to six weeks in a sling
• Rotator cuff tear repair: four to six months of rehabilitation.

7. Can a shoulder dislocate again?

Yes shoulder dislocations can recur, particularly in younger & more active people. Each dislocation episode may further stretch and damage the joint capsule and supporting structures that increases the risk of future joint instability.

8. When is surgery required for a shoulder injury?

Surgery needed for failed closed reduction, recurrent instability in active patients, displaced clavicle fractures, full-thickness rotator cuff tears in active patients, and three or four-part proximal humeral fractures.

9. What are the complications of untreated shoulder dislocation?

Common complications are:

• Axillary nerve damage 
• Axillary artery injury
• Avascular necrosis of the humeral head
• Chronic instability and recurrent dislocation
• Post-traumatic arthritis.

10. How can shoulder injuries be prevented?

Rotator cuff strengthening and scapular stabilisation exercises reduce injury risk; protective equipment in contact sports; and surgical stabilisation after the first dislocation in high-risk young athletes.

11. What role does physiotherapy play in recovery?

Physiotherapy rebuilds rotator cuff strength and scapular control, restores range of motion and reduces the risk of recurrence. It begins within one week of reduction and continues for six to twelve weeks with sport return guided by functional testing.

12. Which shoulder structures are most commonly injured?

Commonly injured structures are:

• The glenohumeral joint (most commonly dislocated large joint)
• The clavicle 
• AC joint 
• Supraspinatus tendon.
