Introduction
Musculoskeletal injuries such as sprains, dislocations, and bruises are among the most frequent accidents encountered both in everyday life and in outdoor environments. Whether caused by a fall, sports activity, or physical exertion, these injuries can range from mild discomfort to serious joint or bone damage.
In emergency situations—particularly when professional medical care is not immediately available—knowing how to assess and manage these injuries correctly can prevent long-term disability, reduce pain, and minimize complications.
This article provides a structured, evidence-based overview of first aid techniques for non-professionals, covering types of injuries, their symptoms, and step-by-step instructions for proper on-the-spot care.
Basics: Understanding Musculoskeletal Injuries
1. Sprain
A sprain is a stretching or tearing of ligaments—the fibrous tissues connecting bones at joints.
Commonly affected joints: ankle, knee, wrist, and thumb.
Typical Causes: sudden twisting, falls, or awkward landings.
2. Dislocation
A dislocation occurs when the bones in a joint are forced out of their normal alignment.
Common locations: shoulder, elbow, finger, hip, knee.
Causes: falls, collisions, or strong impact forces.
3. Bruise (Contusion)
A bruise results from damage to blood vessels under the skin without a break in the surface.
Common sites: soft tissues, muscles, or bones.
Causes: blunt force, falls, or direct hits.

Step-by-Step: First Aid for Sprains
Step 1: Stop Activity
Do not continue moving or walking on the injured limb.
Step 2: Apply R.I.C.E. Method
R – Rest: Avoid weight-bearing and unnecessary movement.
I – Ice: Apply a cold pack or wrapped ice for 15–20 minutes every hour for the first day.
C – Compression: Use an elastic bandage, but not too tight—watch for numbness or tingling.
E – Elevation: Keep the injured limb elevated above heart level to reduce swelling.
Step 3: Pain Control
Administer over-the-counter analgesics such as ibuprofen or paracetamol, if available.
Step 4: Immobilization
If swelling or instability is significant, use a splint or brace to immobilize the joint.
Step 5: Medical Evaluation
Seek professional assessment for severe pain, inability to bear weight, or suspected ligament rupture.
Step-by-Step: First Aid for Dislocations
Step 1: Recognize the Signs
-
Visible deformity of the joint
-
Severe pain and swelling
-
Inability to move the joint
-
Shortened or abnormal limb position
Step 2: Do NOT Attempt to Reset the Joint
Only trained professionals should attempt to reposition dislocated joints. Improper manipulation may cause fractures, nerve injury, or vascular damage.
Step 3: Immobilize
-
Use a sling for shoulder/elbow injuries or a splint for limbs.
-
Immobilize in the position found—do not force movement.
Step 4: Apply Ice
Ice the area for 15–20 minutes every hour to reduce swelling.
Step 5: Treat for Shock
Lay the person down, elevate legs slightly, keep warm, and calm them.
Step 6: Seek Medical Help
All dislocations require urgent medical attention for imaging, pain control, and possible reduction.
Step-by-Step: First Aid for Bruises (Contusions)
Step 1: Cold Application
Apply ice or a cold compress immediately to limit internal bleeding and swelling.
Step 2: Rest
Avoid further strain on the bruised muscle or limb.
Step 3: Compression
A light elastic bandage may reduce swelling in large contusions.
Step 4: Elevation
Elevate the injured area if possible.
Step 5: Monitor
If pain increases, swelling spreads, or movement becomes restricted, suspect a deeper injury (hematoma or fracture).
Signs of Serious Injury
Seek medical evaluation if you observe:
-
Persistent or severe pain
-
Significant swelling or deformity
-
Numbness or tingling
-
Loss of function or circulation
-
Skin color changes (pale, blue)
-
Bone protrusion through the skin
Immobilization Techniques

Notes |
|---|---|---|
|
Ankle |
Elastic bandage or soft splint |
Do not over-tighten |
|
Knee |
Rigid splint or padded board |
Immobilize both above and below the joint |
|
Wrist |
Splint from palm to forearm |
Keep hand slightly bent |
|
Shoulder |
Sling tied to chest |

|
Finger |
Tape to adjacent finger |
Simple and effective |
Recognizing Associated Fractures
Sometimes sprains or dislocations are accompanied by fractures.
Warning signs:
-
Audible crack at the time of injury
-
Visible deformity or angulation
-
Inability to move limb
-
Bone protrusion
-
Intense localized pain
If any of these are present, immobilize and seek emergency care immediately.

FAQs
-
How can I tell if it’s a sprain or fracture?
If you hear a snap, see deformity, or can’t move the limb—suspect a fracture. -
Can I walk on a sprained ankle?
Not initially. Rest until pain subsides; early walking may worsen the injury. -
How long does a sprain take to heal?
Mild: 1–2 weeks; moderate: 3–6 weeks; severe: several months. -
Is a dislocation more serious than a sprain?
Yes. It requires medical treatment and possibly sedation to reposition the joint. -
Should I use ice or heat?
Ice for the first 48 hours, then heat for stiffness relief during recovery. -
What if swelling increases after 24 hours?
Continue rest and ice; if it worsens, consult a doctor. -
Can bruises become dangerous?
Yes, if they are large, painful, or near joints—may indicate internal bleeding. -
Is it okay to massage a sprain?
Not in the first few days. Massage later during recovery may help circulation. -
How tight should a compression bandage be?
Snug but not restrictive; fingers or toes should remain warm and pink. -
Can I use painkillers?
Yes, over-the-counter options like ibuprofen or acetaminophen. -
How to make a sling in the field?
Use a triangular bandage, scarf, or piece of cloth to support the arm. -
What if I’m alone and can’t move?
Immobilize the injury, stay warm, and signal for help—avoid unnecessary movement. -
Can bruises cause clots?
Rarely, but deep muscle contusions can form hematomas requiring drainage. -
Why is elevation important?
It reduces swelling and improves venous return. -
How do I know if circulation is impaired?
Check color, temperature, and sensation below the injury site. -
What happens if a dislocation isn’t treated?
Chronic instability, deformity, and arthritis may develop. -
When can I resume exercise?
Only after pain-free movement and doctor clearance. -
What is a “greenstick injury”?
A partial fracture common in children, often mistaken for a sprain. -
Should I use elastic supports long-term?
No—only during early recovery. Overuse weakens muscles. -
What’s the most important rule?
When in doubt, immobilize and seek professional medical help.
