What is a diaphyseal fracture?
Diaphysis. The diaphysis is the long central portion of the tibia that attaches the proximal or rear portion of the bone to the distal or far part of the bone. Diaphyseal fractures can occur due to direct impact or a twisting or falling injury.
Where is a diaphyseal fracture?
A toddler’s fracture is a spiral or oblique undisplaced fracture of the distal shaft of the tibia with an intact fibula. The periosteum remains intact and the bone is stable. These fractures occur as a result of a twisting injury.
What are the main mechanisms of fractures of the femoral diaphysis?
Trauma is the most common mechanism of femoral shaft fractures, typically involving a direct hit to the thigh or an indirect force transmitted through the knee. Younger individuals generally are engaged in high energy mechanisms such as automobile accidents, frequently resulting in other associated injuries.
What is a diaphyseal fracture of the radius?
Diaphyseal fractures involving the radius and ulna, so called “both-bone” or “double-bone” forearm fractures are common orthopedic injuries. These injuries can result in significant loss of function if inadequately treated.
What is the diaphysis function?
The diaphysis plays an essential role in the structural functionality, the transport of oxygen and immune support, and mineral and fat storage. The medullary cavity, housed within the diaphysis, is where blood products, including red blood cells, white blood cells, and platelets, are formed.
What is the diaphysis made of?
The diaphysis is the main or midsection (shaft) of a long bone. It is made up of cortical bone and usually contains bone marrow and adipose tissue (fat).
What is proximal femoral diaphysis?
The proximal femur includes the head, neck, lesser and greater trochanters, and proximal femoral diaphysis. The internal architecture of the proximal femur is complex, with a series of tension trabeculae, running horizontally, and compression trabeculae, running more vertically (Singh et al. 1970).
What are the most common types of fractures of the femur?
The most common types of femoral shaft fractures include:
- Transverse fracture. In this type of fracture, the break is a straight horizontal line going across the femoral shaft.
- Oblique fracture. This type of fracture has an angled line across the shaft.
- Spiral fracture.
- Comminuted fracture.
- Open fracture.
What does diaphysis mean in anatomy?
Definition of diaphysis : the shaft of a long bone.
What type of bone is found in the diaphysis?
cortical bone
The diaphysis is the main or midsection (shaft) of a long bone. It is made up of cortical bone and usually contains bone marrow and adipose tissue (fat).
What is the primary type of bone found in the diaphysis?
Most of the diaphysis is formed by compact cortical bone, the inside of the metaphysis and the epiphysis, as well as of short tubular and flat bones contains trabecular (cancellous) bone tissue.
What are the types of fracture femur?
What are the four parts of the proximal femur?
Proximal femur includes the femoral head, neck and the region 5-cm distal to the lesser trochanter. There is a 125°–130° inclination angle between the head and neck and the femoral body. Further, there is a 15° anteversion angle between the plane passing through the condyles of the femoral head and the femur neck.
What is the classification of a diaphyseal fracture?
Classification of Diaphyseal Radius and Ulna Fractures. Fractures of the shafts of the radius and ulna often are described in rather imprecise terms such as “both-bone forearm fracture” and “greenstick fracture.” Radiographs confirm the diagnosis of forearm shaft fracture and are the basis for most classification systems.
What are the diaphyses of a bone?
The diaphyses (singular: diaphysis), sometimes colloquially called the shafts, are the main portions of a long bone (a bone that is longer than it is wide) and provide most of their length. The diaphysis has a tubular composition with a hard outer section of hard cortical bone and a central portion with cancellous bone and bone marrow cavity.
What are the signs and symptoms of a diaphyseal fracture?
Signs and Symptoms of Diaphyseal Radius and Ulna Fractures The signs and symptoms indicating fracture of the shafts of the radius and ulna usually are not subtle. Deformity and pain are the classic findings. Patients typically experience exquisite pain emanating from the involved area.
What is the pathophysiology of distal femur fracture?
The distal femur is under a flexing influence by the gastrocnemius. Fractures most often involve the application of a bending load to the femur, with comminution occurring via higher magnitude forces. Torsional loads, in contrast, form a spiral fracture pattern.
