First decide if the bone is broken or dislocated (out of joint), or if the muscles are sprained. It can be very hard to tell these injuries apart, and an x-ray may be necessary to know for sure. If you cannot tell if it is broken, dislocated or sprained, keep the body part still and get help. It is also possible to have a combination of these injuries.

Give paracetamol (acetaminophen) or ibuprofen to help with the pain.

a broken arm.

Misshapen in the middle of a bone or pain at one specific point on the bone, and little or no pain when it is kept still. Sometimes a bone could be broken even without being misshapen. An x-ray can tell you for sure if there is a break.
a dislocated shoulder.

Deformed at a joint or unable to move a joint.
a swollen wrist.
Sprain or Strain

Swelling and pain near a joint.

Broken bones

Keep a broken bone still until someone with experience setting bones can set it and put on a cast. To help keep it still, make a splint from a folded piece of cardboard, a flat piece of board, the stiff spine of a palm frond, or something else straight and hard.

Make a splint

Step 1:
Position the arm in its natural, resting position. The elbow should be bent.

Step 2:
Wrap a layer of bandage, gauze, or thin cloth or use the sleeve.

Step 3: Rest the arm on the splint. Place a roll of fabric inside the hand. For legs, splint along the side.

Step 4: Wrap around the splint with a bandage or strip of fabric to hold it in place.

Leave fingers and toes uncovered and check often that they are warm and have normal feeling.

Make a sling

You can use a sling to protect and support a wounded arm or shoulder.

Set a bone

Wait for the swelling to go away before you set a bone.

If the bone is out of its natural position, setting it will help it heal. But if you do not know how to set a bone correctly, you can cause a lot of damage by doing it wrong. If possible, someone with experience should set a bone. Many communities have experienced bonesetters or community health workers who know how to do this well.

Step 1:
First give pain medicine. You can also give an anti‑anxiety medicine like lorazepam or diazepam to help the person stay calm.

Step 2:
Ask a helper to hold the part close to the body still or tie it to something that will not move.

Step 3:
Pull the more distant part with a slow, steady, strong force. Do not yank, but pull hard enough to separate the bones.

illustration of the below: setting the bones.

Step 4:
When the pieces of bone are separated, gently line up the two edges and let them come back together.

WARNING! Do not try to set a bone if the break seems to go into the joint or if there seems to be more than one break, leaving a “floating” piece of bone in the middle. Do not jerk or force the bones in place. This can cause permanent damage. Get help.

Make a cast

Casts can be made from pieces of cloth and a syrup or plaster mix that dries hard.

In Mexico several different plants such as tepeguaje (a tree of the bean family) and solda con solda (a huge, tree-climbing arum lily) are used to make casts. In India, traditional bone‑setters make casts using a mixture of egg whites and herbs. The methods are similar. Any plant will do if a syrup can be made from it that will dry hard and firm and will not irritate the skin. Usually the plant is boiled in water until a thick syrup forms. Or use Plaster of Paris mixed with water.

Wait until the swelling has gone down before casting. This can take up to a week. In the meantime, support the limb with a splint and sling.

Step 1:
Make sure the bones are aligned. Compare the injured side to the uninjured side to make sure both look and feel the same.

Step 2:
Put the limb into this position:

Step 3:
Wrap the area to be casted in a loose, thin layer of cloth or a few layers of gauze. Cast an area that includes the joint above and below the break.

Step 4:
Then wrap in soft cotton or kapok. Give extra padding to bony parts, but do not over‑pad, especially around the broken part.

Step 5:
Dip strips of flannel, clean sheets, or bandages in the syrup or plaster mixture.

Step 6:
Form a cast all around the area with layers of bandage. Leave fingers and toes uncovered. Keep the cast snug but not tight.

Step 7:
Smooth the inner wrapping over the edge of the cast, like this:

After the cast is on, rest the limb and keep it elevated when possible. Use crutches to avoid putting any weight on a broken leg.

If, at any time after the cast is on, the fingers or toes start to swell, feel more pain, turn red, pale, or blue, or lose feeling, remove the cast immediately. Failing to cut off a cast that is too tight can cause the person to lose the limb.

How long does a broken bone take to heal? A young child heals in a few weeks. An old person’s bones take months and may never heal properly. Keep a cast on the arm for at least a month. Leg casts should stay on for about 2 months.

To remove the cast, soak it in water and carefully cut it off. After the cast is removed, be gentle with the broken limb for the same amount of time as the cast was on. Slowly start normal activities, such as putting weight on an injured leg.

Bone broken through the skin (open fractures)

Open fractures are very likely to become infected. Clean the wound very well with lots of flowing water for 5 minutes or more. Splint the limb, give ceftriaxone, cloxacillin, clindamycin, OR cephalexin and get help.

If you cannot get to help quickly, clean the wound very well and dress it lightly in sterile gauze. Change the gauze often. When there are no signs of infection for 3 days, set the bone, close the wound, and make a cast.

Dislocations (bone out of the joint)

NWTND fa Page 32-2.png

Re-set a dislocated bone as soon as you can. The longer you wait, the more difficult and painful it will be to fix.

The usual method is to pull the bone gently and slowly away from the joint, then let it “pop” back in correctly. Give an anti‑anxiety medicine such as diazepam, and a general pain medicine such as ibuprofen half an hour before you attempt to re-set the bone. If you cannot get the bone back in the joint, get help.

After resetting a dislocated joint, keep it still for 2 or 3 weeks with a brace or sling. Use a general pain medicine such as ibuprofen as needed. As soon as the pain has lessened enough to allow movement, take the joint out of the sling every few hours and gently flex or rotate it. For a shoulder, hang the arm down and let it move back and forth and in small circles. Be gentle with the joint for the following 2 or 3 months. Dislocations take a long time to heal.

If pain is severe after replacing a dislocated joint, there may be a broken bone.

Dislocated shoulder

Pull the bottom of the upper arm strongly and firmly straight down. Or have the person hold a bucket with 5 or 7 kilos of water for about 15 to 20 minutes. This will pull the arm down and the shoulder should go back into place.

illustration of the below: pushing on the scapula.
If the shoulder does not go back into place, gently push on the tip of the scapula (wing bones) with your thumbs. The arm should ‘clunk’ back into place.

Slowly rotate the arm toward you like this. It is best to have a helper holding the person’s body still, so that just the arm moves.

After, sling the arm like this to prevent it from slipping out of the joint again:

Dislocated elbow

Step 1:
Have the person lie down, then place the forearm straight in line with the upper arm to line up the bones.

Step 2:

Have a helper firmly hold the upper arm. Pull the forearm towards you, and gently bend the elbow.

Step 3:

Now push straight down on upper arm as you bend the elbow the rest of the way. You should feel a “clunk.” Splint the elbow to prevent it from slipping out of the joint again.

IMPORTANT! If there is a lot of resistance, stop! You may break the bone. Splint the elbow like this and get medical help.

Dislocated finger

Firmly pull a dislocated finger out, and then push the base of the bone into place to set it.

Sprains and strains (twisting or tearing under the skin)

NWTND fa Page 35-1.png
  • Swelling
  • Pain
  • Bruising or redness
  • Rest: do not put weight on the injured part. Use a sling or crutches for 3 or 4 weeks.
  • Ice: for about 30 minutes every 2 to 4 hours. Less often after a few days.
  • Compression: wrap firmly with a bandage.
  • Elevation: elevate on a pillow or folded blankets all the time at first, and every few hours after a few days.

These measures will lessen pain and swelling. If done right away and regularly, they will help the injured part heal more quickly and with fewer lasting problems.

Keep pressure and weight off the injury. Usually sprains and strains take 1 to 2 weeks to heal.

toes or fingers.
Wrap firmly, but not too tight. The toes or fingers should feel warm
and have normal felling in them.
