Sprains, Strains, Breaks: What’s the Difference?
If you've sprained your ankle, you know what severe pain is.
But maybe that "sprain" was a "strain" or possibly even a "break."
The amount of pain in each case can be virtually equal. So, oftentimes the only way
to find out what you have is to see a healthcare provider.
Just the facts
Here are some facts on musculoskeletal injuries:
Sprains are a stretch and/or tear of a ligament, the tissue connecting 2 bones. Ligaments
stabilize and support the body's joints. For example, ligaments in the knee connect
the upper leg with the lower leg. This lets you walk and run.
Strains are a twist, pull and/or tear of a muscle and/or tendon. Tendons are cords
of tissue that connect muscles to bones.
Breaks are a fracture, splinter or complete break in bone, often caused by accidents,
sports injuries or bone weakness.
A sprain is caused by an injury that stresses a joint and overstretches or even ruptures
supporting ligaments. This can happen from a fall, twist, or blow to the body,
In a mild sprain, a ligament is stretched, but the joint remains stable and is not
loosened. A moderate sprain partially tears the ligament, causing the joint to be
unstable. With a severe sprain, ligaments tear completely or separate from the bone.
This loosening interferes with how the joint functions. You may feel a tear or pop
in the joint. Although the intensity varies, all sprains commonly cause pain, swelling,
bruising, and inflammation.
The ankle is the most commonly sprained joint. And a sprained ankle is more likely
if you've had a previous sprain there. Repeated sprains can lead to ankle arthritis,
a loose ankle or tendon injury.
Acute strains are caused by stretching or pulling a muscle or tendon. Chronic strains
are the result of overuse of muscles and tendons, through prolonged, repetitive movement.
Not getting enough rest during intense training can cause a strain.
Typical symptoms of strain include:
In severe strains, the muscle and/or tendon is partially or completely ruptured, resulting
in serious injury. Some muscle function will be lost with a moderate strain, in which
the muscle/tendon is overstretched and slightly torn. With a mild strain, the muscle
or tendon is stretched or pulled, slightly.
These are some common strains:
Back strain. This happens when the muscles that support the spine are twisted, pulled, or torn.
Athletes who engage in excessive jumping—during basketball or volleyball, for example—are
at risk for this injury.
Hamstring muscle strain. This is when a major muscle in the back of the thigh tears or stretches. The injury
can sideline a person for up to 6 months. The likely cause is muscle strength imbalance
between the hamstrings and the quadriceps, the muscles in the front of the thigh.
Kicking a football, running, or leaping to make a basket can pull a hamstring. Hamstring
injuries tend to happen again.
Bone breaks, unlike sprains and strains, should always be looked at by a healthcare
provider to ensure proper healing. Call your healthcare provider if the pain does
not lessen or if the bone appears to be deformed. Seek urgent medical care if you
have numbness, weakness, or poor circulation in the injured limb.
Athletes are most susceptible
All sports and exercises, even walking, carry a risk of sprains. The areas of the
body most at risk for a sprain depend on the specific activities involved. For example,
basketball, volleyball, soccer, and other jumping sports share a risk for foot, leg
and ankle sprains.
Soccer, football, hockey, boxing, wrestling, and other contact sports put athletes
at risk for strains. So do sports that feature quick starts, like hurdling, long jump,
and running races. Gymnastics, tennis, rowing, golf, and other sports that require
extensive gripping put participants at higher risk for hand strains. Elbow strains
often happen in racquet, throwing, and contact sports.
A severe sprain or strain may need surgery or immobilization, followed by physical
therapy. Mild sprains and strains may need rehab exercises and a change in activity
In all but mild cases, your healthcare provider should evaluate the injury and establish
a treatment and rehab plan.
Meanwhile, rest, ice, compression and elevation (called RICE) usually will help minimize
damage caused by sprains and strains. Start RICE right away after the injury.
RICE relieves pain, limits swelling, and speeds healing. It’s often the best treatment
for soft-tissue injuries, like sprains and strains. Here's what to do:
Rest. Move the injured area as little as possible to allow healing to begin.
Ice. Apply ice right away to reduce inflammation, which causes more pain and slows healing.
Cover the injured area with an ice pack wrapped in a thin towel for about 15 to 20
minutes, 3 to 4 times a day.
Compression. Using a pressure bandage helps prevent or reduce swelling. Use an elastic bandage.
Wrap the injured area without making it so tight that it will cut off the blood supply.
Elevation. Raise the injured area above the level of the heart. Prop up a leg or arm while resting
it. You may need to lie down to get your leg above your heart level.
Do all 4 parts of the RICE treatment at the same time. If you think you have a more
serious injury, like a broken bone, call your healthcare provider right away.
No one is immune to sprains and strains. But here are some tips to help reduce your
risk for injury:
Take part in a conditioning program to build muscle strength.
Do stretching exercises every day.
Always wear shoes that fit properly.
Nourish your muscles by eating a well-balanced diet.
Warm up before any sports activity, including practice, and use or wear protective
equipment that's right for that sport.
