hyperostosis

 [hi″per-os-to´sis]
excessive growth of bony tissue. adj., adj hyperostot´ic.
frontal internal hyperostosis (hyperostosis fronta´lis inter´na) a new formation of bone tissue protruding in patches on the internal surface of the cranial bones in the frontal region, most commonly affecting women near menopause.
generalized cortical hyperostosis a hereditary disorder beginning during puberty, marked by osteosclerosis of the skull, mandible, clavicles, ribs, and diaphyses of long bones, associated with elevated blood alkaline phosphatase.
infantile cortical hyperostosis a syndrome seen in infants under six months of age, marked by fever, arthralgias, and swelling and cortical thickening of facial, trunk, and long bones. Called also Caffey's disease.

hyperostosis fronta´lis inter´na  thickening of the inner table of the frontal bone, which may be associated with hypertrichosis and obesity, most commonly affecting women near menopause.

hyperostosis (hī´pərostō´sis),

n 1. an excessive growth of bone, as in infantile cortical hyperostosis.
n 2. a hypertrophy of bone. See also exostosis.
hyperostosis, infantile cortical (Caffey's disease, Smyth's syndrome),
n a disease of infants; of unknown cause and characterized by tender, soft tissue swelling that is followed by hyperostosis of the cortex of the underlying bone. The mandible, clavicle, and ulna are most frequently affected.

hyperostosis

excessive growth of bony tissue.

craniomandibular hyperostosis
see craniomandibular osteopathy.
diffuse idiopathic skeletal hyperostosis (DISH)
occurs in dogs and pigs; cause unknown, possibly familial in pigs; extensive bone deposition around joints but articular surfaces not affected.
facial hyperostosis
in hyperparathyroidism resorption of cancellous bone, particularly maxillae and mandibles, and the formation of poorly mineralized osteoid and excessive fibro-osseous tissue cause deformities of the face and head that are clinically obvious and may prevent closure of the mouth. Occurs in primary and secondary hyperparathyroidism.
inherited congenital hyperostosis
see juvenile hyperostosis (below).
juvenile hyperostosis
a congenital defect of pigs. The legs of affected newborn pigs are swollen below the elbow. The piglets have difficulty standing and moving around. The bone is thick and the periosteum rough and there is extensive edema. Called also thick forelegs, inherited congenital hyperostosis.
