Twelfth rib syndrome, also known as rib tip syndrome, is a painful condition that occurs as a result of highly mobile floating ribs.It commonly presents as pain that may be felt in the lower back or lower abdominal region as a result of the 11th or 12th mobile rib irritating the surrounding tissues and nervous systems.
Usually, problems with the rib cage cause the most serious health problems for children with Jeune syndrome. Their rib cages (thorax) are smaller and narrower than usual, which inhibits the child's lungs from developing fully or expanding when they inhale. The child may breathe rapidly and shallowly.
Rib fractures usually occur from a direct blow to the chest such as during a motor vehicle collision or from a crush injury. [2] [1] Coughing or metastatic cancer may also result in a broken rib. [1] The middle ribs are most commonly fractured. [5] [1] Fractures of the first or second ribs are more likely to be associated with complications. [6]
Flail chest typically occurs when three or more adjacent ribs are fractured in two or more places, allowing that segment of the thoracic wall to displace and move independently of the rest of the chest wall. Flail chest can also occur when ribs are fractured proximally in conjunction with disarticulation of costal cartilages distally. For the ...
Children in forceful impacts suffer twice as many pulmonary contusions as adults with similar injury mechanisms, yet have proportionately fewer rib fractures. [13] The rates of certain types of injury mechanisms differ between children and adults; for example, children are more often hit by cars as pedestrians. [ 31 ]
A bifid rib is a congenital abnormality of the rib cage and associated muscles and nerves which occurs in about 1.2% of humans. Bifid ribs occur in up to 8.4% of Samoans. [1] The sternal end of the rib is cleaved into two. It is usually unilateral. [2] Bifid ribs are usually asymptomatic, and are often discovered incidentally by chest X-ray.
Chest pain in children is usually evaluated in the emergency departments. It can be distressing for parents and children. Pediatric chest pain differs from chest pain in adults because it is most often unrelated to the heart. [2] The causes of pediatric chest pain vary according to the organ or tissue in the child. that generates the pain.
The Sub-nanostructure of cortical bone may provide one possible explanation for the greenstick fractures in children. On the contrary to adults bone tissue, the low ratio between the mature and the immature enzymatic cross-links in children bone tissue is a potential explanation of the presence of greenstick fractures in children.
