An infection of the bone is known as osteomyelitis. Osteomyelitis is caused by an infection that develops in the bone or spreads to the bone from another area, and may result in the formation of an abscess in the bone that blocks blood supply. In children, this condition commonly affects the long bones of the arms or legs and it is more common in the bones of the spine or hips in adults. Most cases of osteomyelitis are caused by germs or the staphylococcus bacteria, that has spread from infected skin, muscles or tendons. Bacteria may be transmitted from another part of the body, through the blood, to the bones.
Most individuals have bones that are resistant to infection, making osteomyelitis more common in patients with weakened bones or immune systems. This may include individuals who have diabetes, poor circulation, or those who have recently been injured or undergone orthopedic surgery.
X-rays are imaging tests that produce images of the structures inside the body. X-rays use a type of radiation called electromagnetic waves to produce these internal images. As these waves penetrate the body, they are absorbed in different amounts by different body tissues. Bones are dense and absorb X-ray waves very well and the images appear very clearly, but soft tissues do not absorb the X-rays as well and are therefore harder to see on an X-ray image. Often used to confirm a fracture or a break in a bone, X-rays may be used to investigate lung conditions, digestive tract problems, arthritis, heart failure, breast cancer and other conditions.
Open Wounds and Lacerations
An open wound involves a break in the skin or tissue that may be caused by, among other things, accident, injury or animal bite. A laceration is a type of open wound, one with jagged, irregular edges. Open wounds and lacerations typically involve bleeding, redness, swelling, pain, and tenderness. They can occur nearly anywhere on the body, with the upper extremities being a common location for open wounds/lacerations caused by accidents or falls. Deeper wounds or lacerations may require medical attention to prevent infection and loss of function, due to damage to underlying structures such as bone, muscle, tendon, arteries and nerves. Medical care for wounds and lacerations focuses on promoting healing, preventing complications and preserving function. While important, cosmetic results are not the primary consideration for wound repair.
Trigger-point injections treat pain in areas that have developed trigger points, which are knots of muscle that form when muscles contract and but cannot relax. Trigger points are caused by injury to or overuse of the affected muscle; they can also be caused by stress and anxiety. They can irritate the nerves around them, which causes pain in other areas of the body. The chronic pain brought on by trigger points can also decrease the affected muscle’s range of motion.
