Q: This classification method considers articular involvement, as well as radio-carpal and radio-ulnar joints and the presence of absence of an ulnar fracture. There are six varieties of distal radius fractures under the Frykman classification system.  Under this classification system, “Type I” refers to an extra-articular and transverse metaphyseal fracture. “Type II” refers to a “Type I” fracture that also includes a distal ulnar fracture. “Type III” refers to an intra-articular fracture that involves the radio-carpal joint. “Type IV” refers to a “Type III” fracture that also includes a distal ulnar fracture. “Type V” refers to a severe fracture that includes the distal radio-ulnar and radio-carpal joints. “Type VI” refers to a “Type V” fracture that also includes a distal ulnar fracture. This classification method is used for intra-articular fractures only. It considers the shaft, radial styloid, and dorsal medial and palmar medial parts. There are four varieties of distal radius fractures under the Melone classification system.  Under this classification system, “Type I” refers to a fracture that is stable and minimally displaced. “Type II” refers to a die punch fracture of the radioscaphoid joint, which is unstable and moderately to severely displaced. This kind of fracture involved backward angulation and a shortening of the radius, and percutaneous pins are typically used to maintain reduction. In “Type IIb” fractures, there is a double die punch fracture, with fragmentation of both the inner and rear piece. This type of fracture is typically treated surgically, with internal fixation and iliac bone grafting. “Type III” refers to a die punch or lunate load fracture, which also includes a radial shaft fracture that projects forward. The lunate bones puts pressure on the lower end of the radius. The surgical placement of small screws or wires is typically necessary to stabilize the joint. “Type IV” refers to a severe fracture that involves all the major joint articular surfaces, including the radioscaphoid and lunate joints. Broken fragments may be separated widely or rotated. In almost all cases, a “Type IV” fracture needs surgical treatment: open reduction and internal fixation. This classification method is the simplest; it considers only articular involvement and displacement. It also differentiates stable from unstable fractures. There are four varieties of distal radial fractures under the Melone classification system.  Under this classification system, “Type I” refers to an extra-articular and undisplaced fracture. “Type II” refers to an extra-articular but displaced fracture. “Type III” refers to an intra-articular and undisplaced fracture. “Type IV” refers to an intra-articular and displaced fracture.
A: Understand the Frykman classification. Know the Melone classification. Consider the universal classification.

Article: When a boil first begins to develop, the infection will remain fairly deep under the skin. Boils usually start out as a reddish bump about the size of a pea that is painful to the touch. In some cases, the boil may hurt even when you are not touching it.  The skin around the bump may appear swollen and inflamed. Boils can appear anywhere on your body, but they are most likely to develop in areas where you experience a lot of sweating and friction. Common places include the face, neck, armpits, thighs, and buttocks. Keep an eye on the possible boil in the next few days after you first notice it. If it is a boil, it will begin to expand as the abscess under your skin fills with pus. Some boils can grow to around the size of a baseball, but this is uncommon.  You can monitor the growth of the boil by putting a pen mark at its edge so you can see if it expands. Alternatively, you can measure it every day. As the boil grows, it will typically become more painful and softer to the touch. As the boil grows, look for the formation of a yellow or off-white “tip.” This can happen when the pus inside the boil comes to the surface and becomes visible under your skin. In many cases, the pustule will rupture on its own, allowing the boil to drain and heal.  Keep in mind that you may not see the pus if the boil is fresh. Usually, the pus does not become visible until the later stages of the boil. Never attempt to pierce or squeeze the boil to drain the pus. Doing so could cause the infection to spread deeper into your tissues. If you notice that you have what appears to be several boils clustered together, you may have a carbuncle. These infections most commonly appear on the shoulders, back of the neck, or thighs. In addition to pain and swelling, look out for symptoms such as fever, chills, and a general feeling of illness.  A carbuncle may be as big as 4 inches (10 cm) across. They typically take the form of a large, swollen area with a dense cluster of pustules at the highest point.  Carbuncles or severe boils may also cause swelling in your nearby lymph nodes.
Question: What is a summary of what this article is about?
Look for a red, painful bump in your skin. Note whether the bump grows larger in the days after it appears. Check for yellowish pus under the skin in the middle of the bump. Watch out for more severe symptoms that may indicate a carbuncle.

Q: Once the doll's hair is shampooed, set the doll aside for about 10 minutes. This gives the shampoo a chance to soften the hair. This will help remove any tangles and leave the hair soft and shiny. Set the doll aside in a safe place where it's unlikely to be disturbed.
A:
Leave the doll's hair in the bowl for 10 minutes.
