An X ray demonstrating the characteristic finding of lead poisoning in humans—dense metaphyseal lines. Because of their rich blood supply and vascular stasis, metaphyses of long bones are prone to hematogenous spread of osteomyelitis in children. [4]
An X-ray demonstrating the characteristic finding of lead poisoning in humans—dense metaphyseal lines: Specialty: Toxicology: Symptoms: Intellectual disability, abdominal pain, constipation, headaches, irritability, memory problems, inability to have children, tingling in the hands and feet [1] [2] Complications: Anemia, seizures, coma [1] [2 ...
The epiphyseal plate, epiphysial plate, physis, or growth plate is a hyaline cartilage plate in the metaphysis at each end of a long bone.It is the part of a long bone where new bone growth takes place; that is, the whole bone is alive, with maintenance remodeling throughout its existing bone tissue, but the growth plate is the place where the long bone grows longer (adds length).
Metaphyseal dysplasia, or Pyle disease, [3] is a disorder of the bones. It is a rare disease in which the outer part of the shafts of long bones is thinner than normal and there is an increased chance of fractures .
Metaphyseal broadening, irregularity and metaphyseal line of ossification. These abnormalities that are typically encountered in proximal humerus and around the knees are collectively known as "rachitic-like changes". Radiographic lesions of the appendicular skeleton are typically bilateral and symmetric.
An epiphyseal line is an epiphyseal plate that has become ossified. [1] The process of it forming from an epiphyseal plate is named epiphyseal closure . [ 2 ] In adult humans, it marks the point of fusion between the epiphysis and the metaphysis .
Growth arrest lines, also known as Harris lines, are lines of increased bone density that represent the position of the growth plate at the time of insult to the organism and formed on long bones due to growth arrest. They are only visible by radiograph or in cross-section. The age at which the lines were formed can be estimated from a radiograph.
Knees have metaphyseal widening and irregularity while hands have brachydactyly (short fingers) and proximal metacarpal rounding. Flat feet are very common. [2] The spine is normal but may have a few irregularities, such as scoliosis. [citation needed]
