A bone bruise, also called a bone contusion, is an injury that damages bone tissue and causes bleeding and swelling within or around the bone. Unlike a fracture, a bone bruise does not involve a break in the bone, although both injuries can occur together. It can cause deep pain, tenderness, swelling, and stiffness without visible skin discoloration. Recovery may take several weeks to months, depending on the injury’s severity, location, and any associated damage.
Bone bruises can result from falls, direct impacts, sports collisions, or twisting injuries. Because their symptoms overlap with those of fractures and other injuries, a medical professional may need to examine the affected area and recommend imaging to establish the diagnosis.
What Is a Bone Bruise?
A bone bruise occurs when an impact or force damages the internal structure of a bone. The injury can involve bleeding, swelling, and microscopic damage to bone tissue. Although it is different from a fracture, it can still cause significant pain and take time to heal. The medical explanation of bone bruises describes how compressive forces can damage bone tissue and cause bleeding and swelling.
A skin bruise affects small blood vessels beneath the skin, often causing visible discoloration. A muscle bruise affects muscle tissue, while a bone bruise occurs deeper within or around the bone. These injuries differ in depth and the tissues involved, as explained in this overview of skin, muscle, and bone bruises.
Because a bone bruise is beneath the surface, the skin may look normal even when the underlying bone is injured.
What Causes a Bone Bruise, and What Are the Symptoms?
Bone bruises commonly occur after a direct blow, a fall, a sports collision, or a sudden twisting movement. They can also develop during injuries affecting joints, including some knee injuries.
The knee is a common location, but bone bruises can affect other bones and joints, including the ankle, hip, wrist, and shoulder. The hip and shoulder are examples of ball-and-socket joints, which allow movement in several directions.
Common bone bruise symptoms include:
- Deep, aching pain: Discomfort may persist after the initial injury.
- Tenderness: The affected area may hurt when touched or pressed.
- Swelling: Inflammation and fluid buildup can develop around the injured area.
- Stiffness: Moving the affected joint may become uncomfortable.
- Pain with movement or weight-bearing: Walking, exercising, or putting pressure on the injured area may worsen symptoms.
- Limited movement: Pain and swelling may make everyday activities difficult.
Symptoms vary depending on the injury’s severity and location. These signs cannot confirm a bone bruise on their own because fractures and other injuries can cause similar symptoms.
Bone Bruise vs. Fracture: What’s the Difference?
A bone bruise involves damage to bone tissue without a fracture, whereas a fracture involves a break in the bone. Both can cause pain, swelling, tenderness, and difficulty using the affected area. These overlapping symptoms are also common in other bone injuries, including fractures.
| Feature | Bone Bruise | Fracture |
| Injury | Damage within or around bone tissue | A break in the bone |
| Visible bruising | May be absent | May be present or absent |
| Pain and swelling | Common; severity varies | Common; severity varies |
| X-ray findings | Usually does not show the bruise itself | Often identifies the fracture |
| Recovery | Weeks to months or longer | Depends on fracture type and severity |
A bone bruise can occur alongside a fracture or another joint injury. Neither pain intensity nor skin appearance reliably distinguishes these conditions.
How Is a Bone Bruise Diagnosed?
A clinician will usually ask how the injury happened and examine the affected area for tenderness, swelling, movement limitations, and other signs of damage.
X-rays generally do not reveal bone bruises, but they can help identify fractures. If symptoms, examination findings, or the suspected injury warrant further investigation, an MRI may reveal a bone bruise and associated injuries to ligaments or other tissues.
Not everyone needs an MRI. The decision depends on the suspected injury, clinical findings, and whether further imaging would affect treatment. A normal X-ray does not rule out every significant bone injury.
How Is a Bone Bruise Treated?
Bone bruise treatment generally focuses on protecting the injured area, controlling symptoms, and allowing the bone to heal.
- Modify activity: Temporarily avoid sports, running, jumping, and other activities that worsen pain.
- Apply ice: Use an ice pack wrapped in a towel for short periods to help relieve pain and swelling. Avoid placing ice directly on the skin.
- Protect the injured area: Crutches, a brace, or restricted weight-bearing may be necessary when recommended by a clinician.
- Manage pain safely: Appropriate pain-relieving medication may help. Ask a healthcare professional or pharmacist which option is suitable if you have medical conditions, take other medications, or are unsure what to use.
- Follow rehabilitation advice: Exercises to restore movement and strength may be introduced when appropriate, depending on the injury and recovery progress.
Avoid returning to intense exercise too early. Putting too much stress on an injured bone before it has adequately recovered may worsen symptoms or prolong recovery. Follow your clinician’s guidance on when to resume normal activities.
How Long Does a Bone Bruise Take to Heal?
Bone bruise recovery time varies considerably. Some less severe injuries improve within a few weeks, while more substantial bone bruises can take several months or longer to heal.
Recovery depends on the extent of bone damage, the affected location, any associated injuries, and how much stress the area experiences during healing.
Pain may improve before the underlying injury has fully recovered. Feeling better does not automatically mean the bone is ready for intense exercise or competitive sports.
Return to activity should be gradual and guided by symptoms, functional recovery, and medical advice when needed. If pain persists, worsens, or fails to improve as expected, seek further assessment.
When Should You See a Doctor for a Bone Bruise?
Seek prompt medical evaluation after a significant injury, particularly if you have severe or worsening pain, substantial swelling, or difficulty standing or bearing weight. These symptoms may indicate a fracture or another injury requiring treatment.
You should also arrange an assessment if pain persists, movement remains limited, or recovery is not progressing as expected.
After a serious accident or major trauma, seek emergency medical care, especially if there is visible deformity, an open wound over a suspected fracture, numbness, or a cold or pale limb.
A suspected bone bruise should not be diagnosed at home based on symptoms alone. Appropriate assessment can help identify the injury, rule out more serious damage, and guide a safe recovery plan.
Frequently Asked Questions
What does a bone bruise feel like?
A bone bruise often causes deep, aching pain, tenderness, swelling, and stiffness around the injured area. Pain may become more noticeable when you move the affected joint, walk, or put weight on the injured bone. The skin may look normal, even when the injury is significant.
How long does a bone bruise take to heal?
A bone bruise may improve within a few weeks, but more severe injuries can take several months or longer to heal. Recovery depends on the extent of bone damage, the affected area, and whether other injuries are present.
Can you walk with a bone bruise?
You may be able to walk with a mild bone bruise, but walking can worsen pain or delay recovery if it puts too much stress on the injured area. If walking is very painful or you cannot bear weight, seek medical evaluation to rule out a fracture or another serious injury.
Can an X-ray show a bone bruise?
An X-ray usually cannot show a bone bruise directly. It can help identify a fracture, while an MRI may reveal damage and swelling within the bone. A healthcare professional will determine whether further imaging is necessary.
What is the difference between a bone bruise and a fracture?
A bone bruise involves damage to bone tissue without a break in the bone. A fracture is a break in the bone. Both can cause pain, tenderness, and swelling, so symptoms alone cannot reliably distinguish them. Medical assessment and imaging may be needed.
What is the best treatment for a bone bruise?
Treatment usually involves resting or modifying activities, applying ice wrapped in a towel, protecting the injured area, and managing pain safely. Some injuries may require crutches, a brace, or temporary limits on weight-bearing. Follow a healthcare professional’s advice about rehabilitation and returning to exercise.
Can a bone bruise heal on its own?
Many bone bruises heal with time, appropriate activity modification, and protection of the injured area. However, a suspected bone bruise should be assessed when pain is severe, movement is limited, or weight-bearing is difficult because a fracture or associated injury may be present.
When should I see a doctor for a bone bruise?
Seek medical attention if you have severe or worsening pain, significant swelling, difficulty walking or bearing weight, persistent symptoms, or limited movement. After major trauma, visible deformity, an open wound over a suspected fracture, numbness, or a cold or pale limb requires urgent medical care.
