What is metaphyseal line?
Dense metaphyseal bands, less commonly known as dense metaphyseal lines, transverse bands, or ”lead lines,” indicate radiopaque bone (thicker than the adjacent diaphyseal cortex) at the metaphysis of growing bone, particularly at the wrists and knees (Figs 1, 2).
What are Lucent bands?
Lucent Metaphyseal Bands in Leukemia. Disturbance of enchondral bone formation can produce lucent metaphyseal bands (red arrows are oval) as in this patient with leukemia. Gamuts in Radiology. Bone changes in hematologic disease.
What is metaphyseal lucency?
Bilateral metaphyseal lucency was defined as the metaphyseal lucent area in both lower extremities (Fig. 1C). An epiphyseal cortical irregularity was defined as a fragmented appearance at the medial side of the epiphysis in the distal femur (Fig. 2).
Where is the metaphyseal fracture?
Metaphyseal fractures are also known as corner fractures, bucket handle fractures or metaphyseal lesions. It refers to an injury to the metaphysis which is the growing plate at each end of a long bone (such as tibia, femur, etc).
What is the metaphyseal fracture?
Is a metaphyseal fracture the same as an Physeal fracture?
Metaphyseal fractures are fractures that involve the metaphysis of tubular bones. They may occur in pediatric or adult patients. Not all metaphyseal fractures intersect the physis. Even if a fracture does extend to the physis, it does not make it a Salter-Harris fracture.
What does Chondrodysplasia mean?
Medical Definition of chondrodysplasia : a hereditary skeletal disorder characterized by the formation of exostoses at the epiphyses and resulting in arrested development and deformity. — called also dyschondroplasia.
What is a distal radial metaphyseal fracture?
Distal radial fractures are a heterogeneous group of fractures that occur at the distal radius and are the dominant fracture type at the wrist. These common fractures usually occur when significant force is applied to the distal radial metaphysis.
Is Physeal and metaphyseal the same?
Long bones in children have four distinct segments (Figure 1): The epiphysis is the region of bone adjacent to the joint surface. Below it lies the physis, the area where growth occurs. Distal to that is the metaphysis, a flared region of bone, and below that lies the narrower shaft of the bone, or diaphysis.
What is Schmid metaphyseal Chondrodysplasia?
Metaphyseal chondrodysplasia, Schmid type (MCDS), is a very rare inherited disorder characterized by short stature with abnormally short arms and legs (short-limbed dwarfism) and bowed legs (genu varum).
