Metaphyseal tumors or lesions include osteosarcoma, chondrosarcoma, fibrosarcoma, osteoblastoma, enchondroma, fibrous dysplasia, simple bone cyst, aneurysmal bone cyst, non-ossifying fibroma, and osteoid osteoma. [5] One of the clinical signs of rickets that doctors look for is cupping and fraying at the metaphyses when seen on X-ray.
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).
Together with rhizomelic limb shortening, the presence of epiphyseal-metaphyseal changes of the long bones is a distinctive radiologic feature of pseudoachondroplasia. Hypoplastic capital femoral epiphyses, broad short femoral necks, coxa vara, horizontality of acetabular roof and delayed eruption of secondary ossification center of os pubis ...
Pressure epiphysis: The region of the long bone that forms the joint is a pressure epiphysis (e.g. the head of the femur, part of the hip joint complex). Pressure epiphyses assist in transmitting the weight of the human body and are the regions of the bone that are under pressure during movement or locomotion.
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 .
In addition, mottled metaphyseal sclerosis and widening are also present in patients. [4] [9] Development of irregular patchy sclerosis along the bone can also be identified, [9] as well as metaphyseal flaring evolve towards Erlenmeyer flask deformity with nonuniform patches of sclerosis, which are especially prevalent in older patients. [10]
The tumor may be localized at the end of the long bone (commonly in the metaphysis). Most often it affects the proximal end of tibia or humerus , or distal end of femur . Osteosarcoma tends to affect regions around the knee in 60% of cases, 15% around the hip , 10% at the shoulder , and 8% in the jaw .

Also known as the shaft. dia-+ physis, "between the growth parts" epiphysis: The end regions of a long bone; regions of secondary ossification. epi-+ physis, "on top of the growth part" physis (epiphyseal plate) Also known as the growth plate.
