The disorder can be detected by radiograph due to thickening of bony cortex resembling "dripping candle wax." It is included on the spectrum of developmental bone dysplasias including pycnodysostosis and osteopoikilosis. [6] The disorder tends to be unilateral and monostotic (i.e. affecting a single bone), with only one limb typically involved.
High bone density, Acro-osteolysis and obtuse mandibular angle are the characteristic radiological findings of this disorder. [10] Pycnodysostosis also causes problems that may become evident with time. Aside from the broken bones, the distal phalanges and the collar bone can undergo slow progressive deterioration.
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.
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.
The impairment of bone metabolism causes inadequate bone mineralization. Osteomalacia in children is known as rickets, and because of this, use of the term "osteomalacia" is often restricted to the milder, adult form of the disease. Signs and symptoms can include diffuse body pains, muscle weakness, and fragility of the bones.
It is due to a defect in the RUNX2 gene which is involved in bone formation. [1] Diagnosis is suspected based on symptoms and X-rays with confirmation by genetic testing . [ 4 ] Other conditions that can produce similar symptoms include mandibuloacral dysplasia , pyknodysostosis , osteogenesis imperfecta , and Hajdu-Cheney syndrome .
