The injury shown in the picture above represents a Bone  bruise, or contusion

Bone bruise

• It is a traumatic injury to a bone that is less severe than a bone fracture.
  • Bones close to the surface of your skin are more likely to be bruised than other bones.
  • Bone bruises commonly occur in the knee or femur, but can also occur in the wrist, elbow, heel, foot, hip or pelvis.
  • Black and blue mark on skin happens when an injury damages small blood vessels and causes blood and fluid to leak into the nearby tissues and blood vessels.
• There are three types of bone bruises:
  • Subperiosteal hematoma:With a bone fracture, all of the trabeculae in a region of bone have broken. But with a bone bruise, an injury only damages some of these trabeculae. An injury might cause blood to build up in the area beneath the periosteum. This causes a subperiosteal hematoma
  •  Subchondral bruise:An injury might also cause bleeding and swelling in the area between your cartilage and the bone beneath it. This causes a subchondral bone bruise.
  •  Interosseous bruise: bleeding and swelling can happen in the medulla of your bone. This is called an interosseous bone bruise.
• Symptoms:
  • Stiffness
  • Significant pain and swelling
  • The pain is more severe than a soft tissue bruise
  • Tenderness and pain lasting longer than a usual bruise
  • Trouble using an injured joint
• Diagnosis:
  • A bone bruise or contusion is best identified using MRI scan.
  •  A bone bruise doesn’t show up on an X-ray.
