fracture
(noun)
Damage to the continuity of a bone.
(noun)
the act of breaking, or something that has broken, especially that in bone or cartilage.
Examples of fracture in the following topics:
-
Metatarsal Fracture
- Fractures commonly include the 5th metatarsal (a Jones fracture) or fractures of the distal third of one of the metatarsal (March fracture).
- A Jones fracture is a fracture of the diaphysis of the fifth metatarsal of the foot .
- If a Jones fracture fails to unite, which is a common problem with these fractures, it can become a chronic condition.
- A March fracture, also known as fatigue fracture or stress fracture of metatarsal bone, is the fracture of the distal third of one of the metatarsals occurring because of recurrent stress, such as is sustained by soldiers during prolonged periods of marching.
- Analyze why a Jones fracture of the 5th metatarsal often does not heal and the causes of a March fracture of the metatarsal bone
-
Hip Fracture
- A hip fracture is a femoral fracture that occurs in the proximal end of the femur (the long bone running through the thigh) near the hip.
- A hip fracture is a femoral fracture that occurs in the proximal end of the femur (the long bone running through the thigh) near the hip .
- Hip fractures are often due to osteoporosis.
- In the vast majority of cases, a hip fracture is a fragility fracture due to a fall or minor trauma in someone with weakened osteoporotic bone.
- Patients with hip fractures are at high risk for future fractures, including hip, wrist, shoulder, and spine.
-
Fractures
- Fractures can occur in bones throughout the body.
- A spinal fracture (or vertebral fracture) is a fracture affecting the bones of the spinal column.
- A rib fracture is a break or fracture in one or more of the bones making up the rib cage.
- The term "hip fracture" is commonly used to refer to four different fracture patterns and is often due to osteoporosis; in the vast majority of cases, a hip fracture is a fragility fracture due to a fall or minor trauma in someone with weakened osteoporotic bone.
- A clavicle fracture is a bone fracture in the clavicle, or collarbone.
-
Fractures of the Vertebral Column
- A spinal fracture (or vertebral fracture) is a fracture affecting the bones of the spinal column.
- A spinal fracture (or vertebral fracture) is a fracture affecting the bones of the spinal column.
- A compression fracture is a collapse of vertebra.
- A cervical fracture is commonly called a broken neck .
- Considerable force is needed to cause a cervical fracture.
-
Clavicle Fracture
- A clavicle fracture is a bone fracture in the clavicle or collarbone.
- A clavicle fracture is a bone fracture in the clavicle or collarbone .
- Children and infants are particularly prone to clavicle fracture.
- Newborns often present clavicle fractures following a difficult delivery.
- The clavicle is usually fractured in the middle third of its length, which is its weakest point.
-
Bone Repair
- Bone fractures are repaired through physiological processes in the periosteum via chrondroblasts and osteoblasts.
- Bone healing, or fracture healing, is a proliferative physiological process in which the body facilitates the repair of a bone fracture.
- Days after a fracture, the cells of the periosteum replicate and transform.
- When the humerus in the upper arm is fractured and properly set, bone healing can repair the bone.
- This figure depicts a communitive midshaft humeral fracture with callus formation.
-
Fracture
- Fracture strength, also known as breaking strength, is the stress at which a specimen fails via fracture.
- The final recorded point is the fracture strength.
- Bones, on the whole, do not fracture due to tension or compression.
- Still greater forces permanently deform the object until it finally fractures.
- Note that in this graph the slope increases just before fracture, indicating that a small increase in F is producing a large increase in L near the fracture.
-
Rib Fracture, Dislocation, and Separation
- A rib fracture is a break or fracture in one or more of the bones making up the rib cage.
- Fractures of the first and second ribs may be more likely to be associated with head and facial injuries than are other rib fractures.
- The middle ribs are the ones most commonly fractured.
- The most-commonly fractured ribs are the 7th and 10th.
- Rib fractures are also a sign of more serious injury in elderly people.
-
Aging and the Skeleton
- In osteoporosis, bone mineral density (BMD) is reduced and the integrity of bone proteins is altered, increasing the risk of fracture.
- Osteoporosis is a bone disease that leads to an increased risk of fracture.
- Osteoporosis itself has no symptoms; its main consequence is the increased risk of fractures caused by weakened bones.
- Osteoporotic fractures, called fragility fractures, occur in situations where healthy people would not normally break a bone.
-
Bone Remodeling and Repair
- Bone is remodeled through the continual replacement of old bone tissue, as well as repaired when fractured.
- Bone generation: Within days of the fracture, capillaries grow into the hematoma, while phagocytic cells begin to clear away the dead cells.
- It takes about two months for the broken bone ends to be firmly joined together after the fracture.
- The healing of a bone fracture follows a series of progressive steps: (a) A fracture hematoma forms.
