When you get a scratch or a cut, you open blood vessels and that causes bleeding. While bleeding helps to clean the cut, your body stops bleeding eventually by producing platelets that clump together or coagulate at the spot of the wound. These platelets dry and clot to form a scab. The skin below the scab begins to heal with the help of white blood cells.When the skin is healed, the scab will fall off. This usually happens within a week or two. Although your scab may be itchy because of the healing process beneath it, you should not scratch it. If you pick away your scab you interrupt the healing process and could develop a scar.

What is a ring avulsion (finger avulsion)?
In sport, a ring avulsion is commonly known as a finger avulsion, occurring most commonly when an athlete tries to dunk a basketball and their finger gets caught in the net. If the finger is torn off, it must be found, kept moist or on ice and brought to the emergency room so it can be reattached. This is the primary reason why athletes are not allowed to wear rings in sport.

What are some effects of a hip labral tear?
Scott Martin, MD, Orthopedic Surgery, answeredA hip labral tear may cause immediate symptoms or may not bother you, even while it sets the stage for later joint problems. An injured labrum loses some of its ability to protect and cushion the cartilage lining the socket beneath it. A roughened edge may begin to scrape against cartilage on the ball of the hip joint, leading to osteoarthritis.
