fracture callus

(noun)

A fibrocartilage or fracture callus is a temporary formation of fibroblasts and chondroblasts that form at the area of a bone fracture as the bone attempts to heal itself.

Examples of fracture callus in the following topics:

  • Bone Repair

    • Bone healing, or fracture healing, is a proliferative physiological process in which the body facilitates the repair of a bone fracture.
    • These processes culminate in a new mass of heterogeneous tissue that is known as the fracture callus.
    • Eventually, all of the woven bone and cartilage of the original fracture callus is replaced by trabecular bone, restoring most of the bone's original strength.
    • Eventually, the fracture callus is remodeled into a new shape that closely duplicates the bone's original shape and strength.
    • This figure depicts a communitive midshaft humeral fracture with callus formation.

  • Capacity of Different Tissues for Repair

    • The physiology and process of bone healing has several phases of recovery that help the proliferation and protection of the areas surrounding fractures and dislocations.
    • Usual margins of two to three weeks are given for the reparation of most upper bodily fractures; anywhere above four weeks given for lower bodily injury.
    • The process of the entire regeneration of the bone can depend on the angle of dislocation or fracture.
    • Eventually, all of the woven bone and cartilage of the original fracture callus is replaced by trabecular bone, restoring most of the bone's original strength.
    • Eventually, the fracture callus is remodeled into a new shape that closely duplicates the bone's original shape and strength.

  • 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.
    • But in civilian life, it is seldom diagnosed correctly for a week or two, when, because of lack of immobilization, there is an excessive deposit of callus (which may be palpable) around the fracture.

  • Fractures

  • 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 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.

  • 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 disease of bones that leads to an increased risk of fracture .
    • Osteoporotic fractures are those that occur in situations where healthy people would not normally break a bone.
    • Fractures resulting from osteoporosis are regarded as fragility fractures.
    • Typical fragility fractures occur in the vertebral column, rib, hip, and wrist.

  • 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.

  • Osteoporosis

    • Osteoporosis, the result of reduced bone mineral density, can lead to an increased risk for fractures.
    • Osteoporosis is a disease of the bones that leads to an increased risk of fracture.
    • Its main consequence is the increased risk of bone fractures.
    • They are, therefore, regarded as fragility fractures.
    • Typical fragility fractures occur in the vertebral column, rib, hip, and wrist.
