Leg Injury

Leg Injury

Is this your symptom?

  • Injury to the leg
  • Injury to a bone, muscle, joint or ligament of the leg
  • Note: Muscle pain caused by overuse (too much exercise or heavy lifting) is covered in Leg Pain.

Types

Many leg injuries only damage the skin. Examples of skin injuries are a bruise (contusion), cut (scratch, laceration), and scrape (abrasion):

  • Bruise: The medical term for bruise is contusion. It is caused by a direct blow to the skin and muscles. The skin is not broken and there is no cut. The skin may be puffy or swollen. Pain is usually mild to moderate. Bruises are tender to touch. The bruised skin may first look red, then purple, and finally orange-yellow. These skin color changes are from blood that leaked from tiny torn blood vessels in the bruised area. Most bruises can be treated at home. A cold pack can help reduce the pain and swelling.
  • Cut - Shallow: Shallow cuts (scratches) only go part way through the skin. They rarely become infected. A scratch is an injury to the skin from a sharp edge. For example, scratches can be caused by fingernails, a sharp nail, a piece of metal, or a branch of a tree or bush. A shallow cut or scratch can usually be treated at home. Making sure the wound is clean is the most important thing.
  • Cut - Deep: Deep cuts (lacerations) go through the skin. A laceration is caused by cutting the skin with the sharp edge of an object. This can happen from a knife, a razor, a piece of glass, or the sharp edge of a piece of metal. Making sure the wound is clean is very important. Cuts longer than ½ inch (12 mm) usually need stitches.
  • Scrape: The medical term for scrape is abrasion. This happens when an injury scrapes off the top layer of the skin. An example is when a person falls and "scrapes" his or her knee on a concrete sidewalk. Pain is usually mild. This can usually be treated at home. Making sure the wound is clean is the most important thing.

Sometimes an injury can involve a bone, muscle, joint, or ligament of the leg:

  • Dislocation: This is when a bone comes out of the joint. The joint always looks severely crooked or deformed. The pain is severe. A person with a dislocated hip, knee, or ankle will not be able to walk. This is serious and admission to the hospital is always needed. A doctor will treat this by putting the bone back into the joint socket.
  • Dislocation of Kneecap (Patella): This is when the kneecap slips off the top of the knee joint. The knee joint will look mildly crooked or deformed. A person with a dislocated kneecap will not be able to walk. The pain is moderate to severe. A doctor will treat this by pushing the patella bone back into the right place.
  • Fracture: This is the medical term for a broken bone. It means the same thing as a break or crack in the bone. The pain is severe. A person with a leg fracture usually cannot walk. Surgery may be needed.
  • Patellar Tendon Tear: This is a tear (rupture) of the tendon just below the kneecap. Often a person cannot lift that foot and completely straighten the knee. Surgery is often needed.
  • Quadriceps Tendon Tear: This is a tear (rupture) of the thigh muscle just above the kneecap. Often a person cannot lift that foot and completely straighten the knee. Surgery is often needed.
  • Sprain: A sprain is the medical term used when ligaments around a joint are torn or over-stretched. Ligaments are the bands of tissue that connect bones to each other. This is the same thing as a "twisted knee" or a "twisted ankle". Sprains are common. They happen most often while playing sports. Pain and swelling can be from mild to severe. Most sprains heal with time and rest. Crutches and a knee brace are usually needed.
  • Strain: A strain is the medical term used when muscles are torn or over-stretched. A more common term for this is a "pulled muscle". Strains are common. They are often due to injuries from falling, heavy lifting, and sports. Strains often heal with just time and rest. Surgery is rarely needed for a muscle strain.

Pain Scale

  • None: No pain. Pain score is 0 on a scale of 0 to 10.
  • Mild: The pain does not keep you from work, school, or other normal activities. Pain score is 1-3 on a scale of 0 to 10.
  • Moderate: The pain keeps you from working or going to school. It wakes you up from sleep. Pain score is 4-7 on a scale of 0 to 10.
  • Severe: The pain is very bad. It may be worse than any pain you have had before. It keeps you from doing any normal activities. Pain score is 8-10 on a scale of 0 to 10.

Care Advice

Minor Bruise, Sprain, or Strain

  1. What You Should Know - Direct Blow (Contusion, Bruise):
    • A direct blow to your leg can cause a contusion. Contusion is the medical term for bruise.
    • Symptoms are mild pain, swelling, and bruising.
    • Here is some care advice that should help.
  2. What You Should Know - Bending or Twisting Injury (Strain, Sprain):
    • Strain and sprain are the medical terms used to describe over-stretching of the muscles and ligaments of the leg. A twisting or bending injury can cause a strain or sprain.
    • The main symptom is pain that is worse with movement and walking. Swelling can occur. Rarely there may be slight bruising.
    • Here is some care advice that should help.
  3. Apply a Cold Pack:
    • Apply a cold pack or an ice bag (wrapped in a moist towel) to the area for 20 minutes. Repeat this in 1 hour and then every 4 hours while awake.
    • Do this for the first 48 hours after an injury.
    • This will help decrease pain and swelling.
  4. Apply Heat to the Area:
    • Beginning 48 hours after an injury, apply a warm washcloth or heating pad for 10 minutes three times a day.
    • This will help increase blood flow and improve healing.
  5. Wrap with an Elastic Bandage:
    • Sometimes the pressure from an elastic bandage can help prevent swelling and can make the leg feel better.
    • Gently wrap the injured part of the leg of with an elastic bandage. Leave it in place for 2 days.
    • If you start to get numbness or tingling in your foot or toes, the bandage may be too tight. Loosen the bandage wrap.
  6. Elevate the Leg:
    • Lay down and place the injured leg up on a pillow.
    • This puts the leg above the heart. It helps with pain and it decreases swelling.
    • Do this for 15 to 20 minutes, 2 to 3 times a day, for the first two days.
  7. Rest vs. Movement:
    • Complete rest should only be used for the first day or two after an injury.
    • Staying active helps muscle healing more than resting does.
    • Continue normal activities (like walking) as much as your pain permits.
    • Avoid running and active sports for 1 to 2 weeks or until the pain and swelling are gone.
  8. What to Expect:
    • Swelling and pain from bruises start to get better 2 to 3 days after an injury. Swelling is usually gone by 7 days. It may take 2 weeks for a bruise to fade away.
    • Swelling and pain from strains and sprains start to get better 2 to 3 days after an injury. Swelling is usually gone by 7 days. It may take 1 to 2 weeks for pain to go away.
  9. Call Your Doctor If:
    • Pain becomes severe
    • Pain is not better after 3 days
    • Pain or swelling lasts more than 2 weeks
    • You think you need to be seen
    • You get worse

Minor Cut (Scratch) or Scrape (Abrasion)

  1. What You Should Know:
    • You can treat small shallow cuts and scrapes at home.
    • Here is some care advice that should help.
  2. Bleeding: Apply direct pressure for 10 minutes with a sterile gauze to stop any bleeding.
  3. Cleaning the Wound:
    • Wash the wound with soap and water for 5 minutes.
    • For any dirt, scrub gently with a washcloth.
    • For any bleeding, apply direct pressure with a sterile gauze or clean cloth for 10 minutes.
  4. Antibiotic Ointment:
    • Apply an Antibiotic Ointment (such as OTC Bacitracin), covered by a Band-Aid or dressing. Change daily or if it becomes wet.
    • Option: A TEFLA dressing won't stick to the wound when it is removed.
    • Option: Another option is to use a Liquid Skin Bandage. This only needs to be applied once. Don't use antibiotic ointment if you use a liquid skin bandage.
  5. Liquid Skin Bandage:
    • You can use a liquid skin bandage instead of antibiotic ointment and a dressing or a Band-Aid.
    • Benefits: Liquid skin bandage has several benefits when compared to a regular bandage (such as a dressing or a Band-Aid). You only need to put a liquid bandage on once to minor cuts and scrapes. It helps stop minor bleeding. It seals the wound. This helps it heal faster and keeps out germs. However, it also costs more.
    • How To Use It: First clean and dry the wound. Spray or swab it on the wound. It dries in less than a minute and usually lasts a week. You can get it wet.
    • Examples: Liquid skin bandage is available over-the-counter. Examples include: Band-Aid Liquid Bandage, New Skin, Curad Spray Bandage, and 3M No Sting Liquid Bandage Spray.
  6. Call Your Doctor If:
    • Looks infected (pus, redness, increasing tenderness)
    • Doesn't heal within 10 days
    • You think you need to be seen
    • You get worse

Over-The-Counter Pain Medicines

  1. Pain Medicine:
    • You can take one of the following drugs if you have pain: acetaminophen (Tylenol), ibuprofen (Advil, Motrin), or naproxen (Aleve).
    • They are over-the-counter (OTC) pain drugs. You can buy them at the drugstore.
    • Use the lowest amount of a drug that makes your pain feel better.
    • Acetaminophen is safer than ibuprofen or naproxen in people over 65 years old.
    • Read the instructions and warnings on the package insert for all medicines you take.
  2. Call Your Doctor If:
    • You have more questions
    • You think you need to be seen
    • You get worse
