How to Treat a Contusion: Is it a Wound?

A bruise is simply referred to in medicine as a contusion, a condition that can happen to anyone. Get some tips on how to avoid these and stop further injury.

A contusion is the medical term for a bruise, which is a type of wound. This condition arises from a direct blow by a blunt object or force exerted on the skin and soft tissues beneath it. The damage to the blood vessels causes blood to leak into the tissues. This area will start to swell and turn purple or black. Treatment for a contusion depends on how severe it is. Rest, ice, compression, and elevation can treat minor contusions at home. More severe contusions may require medical treatment.

What is the Meaning of a Contusion?

A contusion occurs when blunt trauma damages the capillaries, small venules, and connective tissue. This results in seepage, buildup or pooling, and the clotting of blood in the interstitial spaces. This can lead to pain and tenderness upon touch. Moreover, it is important to note that a bruise may potentially signify underlying medical conditions and can cause internal organ or tissue damage. Hence, proper evaluation and monitoring are crucial when dealing with a bruise.

Types of Contusion

Contusions can vary in their characteristics and locations based on the nature of the injury. Understanding the different types of contusions can help in their identification and appropriate management. Here are some common types:

Subcutaneous Contusion

Involves the superficial layers of the skin and underlying fatty tissue, resulting in visible discoloration like a bruise on the skin’s surface. However, it is typically not associated with substantial damage to deeper tissues.

Muscle Contusion

Refers to the impact on the muscle tissue, situated beneath the subcutaneous layer. This occurs when blunt force is applied, resulting in localised damage. Muscle contusions often manifest as:

  • pain,
  • swelling,
  • restricted range of motion,

Additionally, bruising and tenderness in the affected area may accompany the injury. Apart from these, complications can arise from these muscle contusions such as compartment syndrome and myositis ossificans both of which will require medical care. The former may require surgery to fix, while both will definitely require physical therapy for recovery.

Bone Contusion (Bone Bruise)

A bone bruise occurs when there is a direct impact on the bone, leading to microscopic fractures or damage to the bone marrow. This type of injury is commonly observed in weight-bearing bones, like the knee or ankle, and is often associated with joint injuries or traumatic incidents. 

A bone contusion manifests as deep, intense pain, along with tenderness and swelling in the affected area. To diagnose this, imaging tests such as magnetic resonance imaging (MRI), CT scan or X-rays are typically required to detect any bone abnormalities. It is important to differentiate a bone contusion from a broken bone to ensure appropriate treatment and management.

Intracranial Contusion

These are contusions that arise within the brain tissue, usually caused by severe head trauma like falls or motor vehicle accidents. This can lead to localised bleeding and swelling in the brain, which may manifest as neurological symptoms including headaches, confusion, or loss of consciousness. Due to the potential for brain damage, immediate medical attention is essential.

Organ Contusion

Typically occurs due to significant blunt force impact to the abdomen or chest area. This type of injury can result in:

  • internal bleeding
  • organ dysfunction
  • potentially life-threatening complications

Therefore, it is crucial to seek prompt physical examination, medical evaluation and intervention from a healthcare professional.

Is a Contusion a Serious Injury?

There are different degrees of severity when it comes to contusions. First-degree bruises, being the least severe, only involve damage to the capillaries, while second-degree bruises involve both capillary and venule damage. Third-degree bruises involve damage to both small and large vessels, as well as the surrounding tissue.

Severe Contusion

A contusion can result in an open wound, laceration, or bone fracture in severe cases. A severe contusion is a serious injury to the tissues and can cause damage to the skin, muscles, and bones. In addition, hematomas can form.

What is a Hematoma?

Severe contusions have the potential to cause hematoma formation, characterised by the accumulation of blood outside the blood vessels. The presence of a hematoma exerts pressure on the surrounding tissue and nerves, resulting in several notable effects such as:

  • pain
  • numbness
  • tingling sensations

In cases where the hematoma grows in size, it can compress blood vessels, impairing blood flow and potentially leading to tissue necrosis (tissue death).

Signs and Symptoms

The most common symptom of a contusion is pain. Depending on the severity of the injury, other symptoms include:

  • swelling
  • tenderness
  • redness
  • warmth to the touch
  • discolouration of the skin (purple, blue, green, yellow)
  • heaviness or aching feeling in the injured area
  • loss of range of motion in the affected area

Causes and Risk Factors of Contusion

Contusions can have many potential origins, but localised trauma is the most frequent. It can happen from a fall, a car accident, or another impact. Some additional factors are:

Contusions can have many potential origins, but localised trauma is the most frequent. It can happen from a fall, a car accident, or another impact.

Bleeding disorders

People with conditions that affect their ability to clot blood are more susceptible to developing bruises.

Medications

Certain medications, such as blood thinners, can make people more likely to develop bruises.

Infants and young children

Their skin is thinner and more delicate than adults, making them more susceptible to bruising.

Older Adults

As people age, the skin becomes thinner and loses some elasticity. This makes it easier for blood vessels to break.

Exposure to cold

Cold temperatures can cause the blood vessels to constrict, which can lead to bruising.

Nutritional deficiencies

People deficient in vitamins C, K, and B12 are more likely to bruise easily.

People with certain medical conditions

Conditions that affect the blood vessels, such as diabetes and vascular disease, can increase the risk of bruising.

People who participate in contact sports

In Australia, sports injuries that commonly result in contusions include contact sports like rugby, football, and hockey, as well as activities involving high impact or collisions, such as martial arts or skateboarding.

People who have had recent surgery

Surgical procedures can damage blood vessels and lead to bruising.

Can a Contusion Cause Nerve Damage?

If the intensity of the trauma is significant to compress or stretch the nerve, a contusion may result in nerve injury. In extreme circumstances, a contusion can cause total loss of sensation in the injured area. A doctor’s check is a must so that the extent of the damage can be determined and treated accordingly.

Contusion Treatment

Treatment for a contusion typically involves the RICE method:

  • Rest: Avoid activity that causes pain or further injury.
  • Ice: Apply ice or cold packs to the injured area for 20 minutes several times a day.
  • Compression: Use an elastic bandage to help reduce swelling.
  • Elevation: Keep the injured area above your heart’s level to help reduce swelling.

Treatment for a contusion typically involves the RICE method:

What to do if the Patient has a Contusion?

Most contusions can be treated at home with simple self-care measures, which include:

  • Follow RICE
  • Taking OTC pain medications such as NSAIDs for pain relief

Over-the-counter pain medications, such as nonsteroidal anti-inflammatory drugs (ibuprofen) or acetaminophen, can also be used to help relieve pain. If the pain is severe or there are signs of an open wound or bone fracture, seek medical attention immediately.

In Severe Cases

Most contusions will heal on their own within a few weeks. However, more severe contusions may require medical treatment and can take longer to heal. Tests and treatment may involve, but are not limited to:

  • x-rays or other imaging tests to assess the extent of the injury
  • blood tests to check for internal bleeding
  • intravenous fluids to treat or prevent dehydration
  • pain medication
  • surgery to repair damaged blood vessels or tissues

If you suspect that you, another person, or someone else has suffered a severe contusion, it is crucial to get checked and receive medical advice promptly. The sooner the patient is seen by a medical professional, the better their chances of making a full recovery. Early diagnosis and treatment can help speed up healing and prevent further complications.

Complications Associated with Severe Contusions

If a contusion is left untreated, it can lead to complications such as:

  • Infection
  • Nerve damage
  • Muscle weakness
  • Joint stiffness
  • Loss of function in the affected area

Severe cases can also lead to life-threatening conditions such as internal bleeding and shock.

How to Prevent a Contusion?

You may stop bruising or contusions from happening in some different ways. These techniques are:

Wearing protective gear: This is very important if you participate in contact sports. Wearing padding on your knees, elbows, and other vulnerable areas can help to cushion blows and reduce the risk of bruising.
Avoiding injury: The best way to prevent bruising is to avoid injury altogether. Be careful when participating in physical activities, and always use caution when handling equipment or tools.
Using ice: If you suffer a minor injury, applying ice packs to the area can help reduce swelling and pain. Ice should be applied for 20 minutes at a time and can be repeated every two hours as needed.
Elevating the injured area: If you have a bruise on your leg or arm, elevating the limb can help to reduce swelling. Try to keep the affected area elevated above the level of your heart.
Wearing loose clothing: Wearing clothing that is tight or constrictive can increase the risk of bruising. Loose, comfortable clothing is best.
Taking care of your skin: Eating a healthy diet and getting enough vitamins and minerals can help to keep your skin firm and less susceptible to injury. Additionally, staying hydrated and drinking lots of water maintain your skin’s elasticity and prevent bruises from forming.

Conclusion

Bruises or contusions are among the most frequent injuries sustained by active children and adults. This can be avoided with extra care and added protection. Recovery for contusions will require professionals knowledgeable in sports medicine.

If this is encountered in the workplace or elsewhere, first aid knowledge and skills will be instrumental in preventing further harm. If you are looking for a first aid course at Level 1/174 Gilles St, Adelaide 5000, contact CPR First Aid for more information.

FAQs

The speed of healing for a contusion varies depending on its severity, but generally, mild to moderate contusions can take about 1 to 2 weeks to heal, while more severe contusions may require several weeks or longer for complete recovery.

Pain experienced from a contusion can differ based on the injury's severity and an individual's pain tolerance. Mild contusions may cause minor discomfort and tenderness, while more severe contusions can result in significant pain, swelling, and bruising.

In most cases, contusions do not require surgery and can be managed through non-surgical treatments such as rest, ice, compression, and elevation (RICE), pain medication, and physical therapy. However, in rare instances where there are complications or severe internal bleeding, surgical intervention may be necessary to address the underlying issues.

Comparing a contusion and a fracture, it is generally understood that fractures involve a broken bone, while contusions refer to tissue damage resulting in bruising. In terms of severity, fractures are typically considered more serious, while contusions usually involve tissue inflammation.

A contusion can lead to complications such as increased pain, swelling, and bruising. Additionally, untreated contusions may prolong the healing process and potentially result in the development of complications like infection or hematoma formation.
