What does distal femur mean?
The distal femur is the area of the leg just above the knee joint. Distal femur fractures most often occur either in older people whose bones are weak, or in younger people who have high energy injuries, such as from a car crash.
Where is the distal femoral metaphysis?
It is classically, located in the medullary cavity of long bone epiphyses, and apophyses, and it is rarely, found in the cortex of the long bone metaphysis.
Where is the distal thigh?
The distal femur is the bottom part of your thigh bone. It is a trapezoidal shaped bone that makes up the top of your joint and sits just behind your knee cap. Your knee is the largest weight-bearing joint in the body. The end of the bone is covered with a smooth surface called articular cartilage.
What are 4 types of empathy?
Examples of empathy types
- Understand the emotional states of the other (cognitive).
- Feel what the other is feeling (affective).
- Have an inclination to help (compassionate).
- And subconsciously respond to what you understand and feel (motor).
What causes the widening of the distal femoral metaphyses?
Symmetric and marked widening of the distal femoral metaphyses with bone infarcts. Diffuse osteopenia. Thin and porous cancellous bone. Hemolytic anemia due to enzymatic defects in heme synthesis, which results in the accumulation and increased excretion of porphyrins or porphyrin precursors.
How big is the distal end of the femur?
The distal end of the femur traditionally encompasses the lower third of this bone. This zone varies greatly in the literature, from the distal 7.6 cm to the distal 15 cm of the femur. This chapter deals only with fractures that involve the supracondylar (metaphyseal) or intercondylar (epiphyseal) areas of the distal end of the femur.
Where is the transition zone in the distal femur?
Distal femoral fractures that are purely diaphyseal are discussed in Chapter 52. BONE. The supracondylar (metaphyseal) area of the distal portion of the femur is the transition zone between the distal diaphysis and the femoral articular condyles (Fig.
Can a metaphysis extend into a diaphysis?
Healing with periosteal new bone formation may extend into the diaphysis. Normal width of the native metaphysis may sometimes be discerned within the periosteal new bone of the healing fracture. Follows metaphyseal fracture of infancy (child abuse, osteogenesis imperfecta).
