Calcification of Costal Cartilage in the Adult Rib Cage
Costal cartilage bridges the sternum and the ribs and plays a key role in the biomechanics of the chest. Costal cartilage is known to calcify in local regions with age, which can substantially stiffen its overall response to loading. However, the rate of accumulation of the calcified volume is not well quantified. Current computational models of the thorax assign a homogeneous sof...
متن کاملFracture of the Costal Cartilage: Computed Tomography Assists Diagnosis
Rib fractures are common and almost always involve the osseous component of a rib. They are typically diagnosed on plain film. Fractures of the costal cartilage are rare and are invisible on plain film. We describe a case in which computed tomography aided in the visualisation of a displaced cartilaginous fracture. To our knowledge, computed tomography-assisted diagnosis of a displaced costal f...
متن کاملAssociation of inorganic pyrophosphatase activity with normal calcification of rat costal cartilage in vivo.
1. Dialysed extracts of rat costal cartilage were shown to possess an enzyme that hydrolyses inorganic pyrophosphate. 2. Inorganic pyrophosphatase activity assayed in the presence of 2mm substrate was maximal at pH6.8. 3. Mg(2+) was essential for activity, which was greatest with 10mm or higher concentrations of Mg(2+). 4. Extracts prepared from cartilage taken from suckling rats (<20g.) showed...
متن کاملUltrasonographic evaluation of calcification patterns in costal cartilage: implications for rib graft harvesting.
IMPORTANCE Complex augmentation rhinoplasty often requires the use of cartilaginous grafts, especially in revision surgery. When using costal cartilage, the possibility of inadequate cartilage material because of excessive calcification must always be kept in mind. Furthermore, cartilage may be harvested but found to be not ideal, causing unsatisfying results. OBJECTIVE To report our experien...
متن کاملMechanical Characterization of Costal Cartilage
Rib fractures are a common morbidity following automotive crashes. While the rib bones are wellcharacterized, and articular cartilage from joints such as the knee and shoulder has been extensively mechanically characterized, almost no mechanical examination has been performed of the rib-cage costal cartilage. Costal cartilage is a hyaline cartilage, like articular cartilage, but it differs from...
