If the bone breaks in such a way that bone fragments stick out through the skin, or a wound penetrates down to the broken bone, the fracture is called an open fracture. This type of fracture is particularly serious because once the skin is broken, infection in both the wound and the bone can occur.
What is poor formation of bone called?
Osteoporosis, or weak bones, is a disease that causes bones to become brittle and more likely to fracture (break). With osteoporosis, the bones lose density. Bone density is the amount of calcified bone tissue that is in your bones.
Which term describes a fracture in which the bone has been twisted apart?
Fracture, spiral: A fracture, sometimes called a torsion fracture, in which a bone has been twisted apart.
What is spongy porous bone tissue called?
Cancellous tissue, also known as cancellous bone, spongy bone or trabecular bone, is characterized by its spongy, porous, honeycomb-like structure and is typically found at the ends of long bones.
What are the 4 types of bone fractures?
Although there are many types of bone fractures, there are four main categories a fracture usually falls under: displaced, non-displaced, open and closed. We’ll start with the most grueling first: open and closed fractures. A closed fracture describes the bone breaking with no puncture through the skin.
What are the 7 types of fractures?
- Transverse fracture. A transverse fracture occurs when a bone breaks at a 90-degree angle to the long axis of the bone.
- Oblique fracture.
- Comminuted fracture.
- Greenstick fracture.
- Stress fracture.
- Pathologic fracture.
What is the name of bone formation?
Bone ossification, or osteogenesis, is the process of bone formation.
What are the two types of bone formation?
There are two types of ossification: intramembranous and endochondral.
What is osteoporosis simple?
Overview. Osteoporosis causes bones to become weak and brittle — so brittle that a fall or even mild stresses such as bending over or coughing can cause a fracture. Osteoporosis-related fractures most commonly occur in the hip, wrist or spine. Bone is living tissue that is constantly being broken down and replaced.
What are the 3 types of fractures?
- Closed or open fractures: If the injury doesn’t break open the skin, it’s called a closed fracture.
- Complete fractures: The break goes completely through the bone, separating it in two.
- Displaced fractures: A gap forms where the bone breaks.
What are the 5 types of fractures?
- Open (compound) fracture.
- Stress fracture.
- Comminuted fracture.
- Greenstick fracture.
- Compression fracture.
Which type of fracture occurs when a bone fragment is driven into another bone fragment?
Comminuted fracture: a fracture in which the bone fragments into several pieces. An impacted fracture is one whose ends are driven into each other. This is commonly seen in arm fractures in children and is sometimes known as a buckle fracture.
What is porous bone called?
What is osteoporosis? The word ‘osteoporosis’ means ‘porous bone. ‘ It is a disease that weakens bones, and if you have it, you are at a greater risk for sudden and unexpected bone fractures. Osteoporosis means that you have less bone mass and strength.
What is spongy bone?
Spongy (cancellous) bone is lighter and less dense than compact bone. Spongy bone consists of plates (trabeculae) and bars of bone adjacent to small, irregular cavities that contain red bone marrow. The canaliculi connect to the adjacent cavities, instead of a central haversian canal, to receive their blood supply.
What are the small holes in bones called?
Remember that organs, including bones, need three connections: blood vessels (both arteries and veins), lymphatics, and nerves. These structures enter the bone through little holes called foramina. A hole specifically for blood vessels is called a nutrient foramen (the singular form of foramina).
What are the 10 types of fractures?
- Avulsion. An avulsion fracture occurs when a connective tendon or ligament pulls a part of bone off, separating it from the rest of the bone.
- Comminuted.
- Compression.
- Greenstick.
- Impacted.
- Oblique.
- Pathological.
- Spiral.
What is the most common type of fracture?
The collarbone, or clavicle, is one of the most frequently broken bones. It’s the most common type of fracture in children and teens. Seniors usually break their collarbones from a hard fall. Younger adults, teens, and children are more likely to break their collarbone in a car accident or from playing sports.
What are types of bones?
- Long bone – has a long, thin shape.
- Short bone – has a squat, cubed shape.
- Flat bone – has a flattened, broad surface.
- Irregular bone – has a shape that does not conform to the above three types.
What are the names of fractures?
- Transverse Fracture. Transverse fractures are breaks that are in a straight line across the bone.
- Spiral Fracture.
- Greenstick Fracture.
- Stress Fracture.
- Compression Fracture.
- Oblique Fracture.
- Impacted Fracture.
- Segmental Fracture.
What is a simple bone fracture?
A simple fracture is a result of excessive force or impact on the bone, resulting in a break. A fracture can be complete, breaking into two pieces, or incomplete, when the bone is cracked but not all the way through. When a bone breaks through the skin and is exposed, this is considered a compound fracture.
How many types of fracture are there?
There are many types of fractures, but the main categories are displaced, non-displaced, open, and closed. Displaced and non-displaced fractures refer to the alignment of the fractured bone.
What are the 3 stages of bone development?
The process of bone formation is called osteogenesis or ossification. After progenitor cells form osteoblastic lines, they proceed with three stages of development of cell differentiation, called proliferation, maturation of matrix, and mineralization.
What an epiphysis is?
Definition of epiphysis
1 : a part or process of a bone that ossifies separately and later becomes ankylosed to the main part of the bone especially : an end of a long bone. 2 : pineal gland.
What is bone tissue?
(… TIH-shoo) Tissue that gives strength and structure to bones. Bone is made up of compact tissue (the hard, outer layer) and cancellous tissue (the spongy, inner layer that contains red marrow). Bone tissue is maintained by bone-forming cells called osteoblasts and cells that break down bone called osteoclasts.
What is a Greenstick?
A greenstick fracture occurs when a bone bends and cracks, instead of breaking completely into separate pieces. The fracture looks similar to what happens when you try to break a small, “green” branch on a tree. Most greenstick fractures occur in children younger than 10 years of age.
