What is the meaning of stippled epiphyses?

[ stĭp′əld ] n. A congenital abnormality of the epiphyses marked by multiple ossification centers that severely deform the long bone and give it a stippled appearance and a thickened shaft.

What is stippling of bones?

Stippled epiphyses is a pattern of focal bone calcification. It is seen in chondrodysplasia punctata. It is also caused by use of warfarin, alcohol, and in hypothyroidism.

What an epiphysis is?

epiphysis, expanded end of the long bones in animals, which ossifies separately from the bone shaft but becomes fixed to the shaft when full growth is attained. The epiphysis is made of spongy cancellous bone covered by a thin layer of compact bone.

What is atavistic epiphysis?

Atavistic epiphysis- femur, Phylogenetically an. independent bone which in man become fused. to another bone e.g. coracoid process of. scapula & os trigonum.

What is stippled calcification?

Definition. An abnormal punctate (speckled, dot-like) pattern of calcifications in soft tissues within or surrounding bones (as observed on radiographs). [ from HPO]

What is Rhizomelic Chondrodysplasia Punctata?

Rhizomelic chondrodysplasia punctata (RCDP) is a type of peroxisomal disorder which impairs the normal development of many parts of the body. It is characterized by shortening of the bones in the upper arms and thighs (rhizomelia).

Where is epiphysis of the bone?

The epiphysis lies between the growth plate (physis) and the joint at the end of the bone (Figure 8). In mice and humans, most tubular bones develop an epiphysis at both ends. Some bones, such as the phalanges and the metacarpal and metatarsal bones, ordinarily form this structure at one end only.

What is epiphysis and types?

Epiphysis: The ends of long bones that ossify from the secondary centre of ossification are called epiphysis. Epiphyses are made of spongy bone covered by a thin layer of compact bone. Epiphyses contain red bone marrow, which produces blood cells (haemopoiesis).

What are the types of epiphyses?

There are two types of epiphyses: (1) pressure epiphyses, which are found at the ends of long bones, and (2) traction epiphyses (apophyses), which are sites of origin or insertion of major muscles (e.g., the greater trochanter of the femur). The metaphysis is an area between the diaphysis and epiphysis.

What is an example of atavism?

This phenomenon is known as atavism. The common example is the presence of the legs in the case of snakes. Snakes are the reptiles which have lost their legs over the time of evolution. Due to atavism, there may be development of small legs in the snakes.

What causes a calcification?

Causes of calcification infections. calcium metabolism disorders that cause hypercalcemia (too much calcium in the blood) genetic or autoimmune disorders affecting the skeletal system and connective tissues. persistent inflammation.

When does calcification occur?

Calcium is one of the most abundant minerals in the body. It is present in the bones, teeth, and bloodstream. If calcium deposits form, the medical names for this is “calcification.” Calcification can occur with age, but it can also be linked with infections, injuries, and cancer.

What is Osteochondrodysplasia?

The osteochondrodysplasias are a heterogeneous group of disorders characterized by abnormal growth and remodeling of cartilage and bone, affecting from 2 to 4.7 per 10,000 individuals. Most osteochondrodysplasias are heritable and many have elaborate patterns of genetic transmission.

What is Diastrophic movement?

diastrophism, also called tectonism, large-scale deformation of Earth’s crust by natural processes, which leads to the formation of continents and ocean basins, mountain systems, plateaus, rift valleys, and other features by mechanisms such as lithospheric plate movement (that is, plate tectonics), volcanic loading, or …

How tall are people with diastrophic dysplasia?

The condition causes decreased sulfate content in the body, which affects cartilage. This, in turn, affects bone growth and height. The average height of people with diastrophic dysplasia is 50 to 53 inches. The taller the patient, the less severely he or she is affected.

Why is the epiphysis important?

The epiphysis is the area of the long bone where bone growth takes place. Long bones actually grow from the inside out. When the bones need to grow, they grow from the epiphyseal plate and push new bone outward. When the bone is done growing, the epiphyseal plate stops creating cells.

What is the prognosis of epiphyseal stippling in children?

Children surviving beyond infancy show gradual disappearance of the stippling, most commonly within the first 2 years (Wardinsky et al. 1990). Once stippling has dissolved, it is replaced most commonly by permanent epiphyseal abnormalities.

What is epiphysial dysplasia?

All rights reserved. a developmental disorder characterized by epiphysial stippling, coronal clefting of the vertebrae, dwarfism with rhizomelic shortening of the limbs, joint contractures, congenital cataracts, ichthyosis, and mental retardation. Autosomal dominant and recessive and X-linked forms exist.

What is an aberrant pattern of epiphyseal calcification?

This aberrant pattern of epiphyseal calcification, which is clearly different from the epiphyseal irregularities that represent normal developmental variations (Swischuk and John 1995), occurs most typically in chondrodysplasia punctata. Patterns vary among different types to some extent (Theander and Pettersson 1978).
