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 .
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]
Verloes Van Maldergem Marneffe syndrome, also known as microspherophakia-metaphyseal dysplasia is a very rare genetic disorder which is characterized by flattened and deformed vertebrae, developmental delay, dysplasia of the epiphyses and metaphyses, lens coloboma and dislocation, microspherophakia, nearsightedness, retinal detachment, and spinal stenosis.
The signs and symptoms of this condition at birth are very similar to those of spondyloepiphyseal dysplasia congenita, a related skeletal disorder. Beginning in childhood, the two conditions can be distinguished in X-ray images by changes in areas near the ends of bones (metaphyses).
Angel-shaped phalango-epiphyseal dysplasia, also known as peripheral dysostosis, is a rare type of osteochondrodysplasia which is characterized by angel-shaped middle phalanges of the fingers and generalized metaphyseal dysplasia/delayed osseous age. [1] [2] Additional findings include joint hypermobility, hypodontia, and hip osteoarthritis ...
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 ...
Craniometaphyseal dysplasia is diagnosed based on clinical and radiographic findings that include hyperostosis. Some things such as cranial base sclerosis and nasal sinuses obstruction can be seen during the beginning of the child's life.
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.
