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.
Idiopathic osteosclerosis, also known as enostosis or dense bone island, is a condition which may be found around the roots of a tooth, usually a premolar or molar. [2] It is usually painless and found during routine radiographs as an amorphous radiopaque (light) area around a tooth.
Osteopoikilosis is a benign, autosomal dominant, sclerosing (hardening) dysplasia of bone characterized by the presence of numerous bone islands in the skeleton. [ 1 ] Presentation
Osteosclerosis is a disorder characterized by abnormal hardening of bone and an elevation in bone density. It may predominantly affect the medullary portion and/or cortex of bone. Plain radiographs are a valuable tool for detecting and classifying osteosclerotic disorders. [1] [2] It can manifest in localized or generalized osteosclerosis.
Exostoses can cause chronic pain ranging from mild to debilitatingly severe, depending on the shape, size, and location of the lesion. It is most commonly found in places like the ribs, where small bone growths form, but sometimes larger growths can grow on places like the ankles, knees, shoulders, elbows and hips. Very rarely are they on the ...
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).
A bone spur (osteophyte) in the knee is mainly caused by wear and tear of the joint, leading to pain and stiffness. Learn more about the causes and treatment.
It can thus serve as a surrogate radio-opaque marker of the posterior border of the knee's synovium. On a lateral radiograph of the knee, an increase in the distance from the fabella to the femur or to the tibia can be suggestive of fluid or of a mass within the synovial fossa. This is of particular use in radiographic detection of knee ...
