In the sternum of two male B6C3F1 (SPF) mice used in a 104-week oncogenicity study, there was a developmental abnormality, not visible at necropsy. In one case, there was a large peripheral nerve of unknown origin located at a lateral parallel position to the normal appearing sternal segment. In the other case, there was a misshaped sternum with shorten segments and a cleft (sternoshisis). With...

The dose distributions for a patient with cancer involving the sternum were calculated for both a kilovoltage x-ray beam and a megavoltage electron beam. The minimum target dose and dose uniformity over the target volume were significantly better using electrons (90%-101%) than kilovoltage x-rays (68%-119%). The calculated lung dose and integral patient dose were also less for electrons than ki...

Methods 20 SD patients with thoracic kyphosis aged 10 to 18 years were included in this study. 30 healthy volunteers were recruited to serve as controls. Computed tomography 3D reconstruction of the total sternum in supine position was performed. The length, width, thickness of manubrium and mesosternum was measured respectively. Meanwhile, the angle (a) between the axis of manubrium and that o...

: Sternal closure after median sternotomy traditionally uses a stainless steel wire cerclage. wires are placed through or around the sternum, and ends twisted together to bring sternum back together. Complications of this technique include sternal instability, dehiscence, non-union, increased pain. Compared traditional cerclage, Figure 8 FlatWire Closure System has been demonstrated be stronger...

A 79-year-old man was admitted for aortic valve replacement 10 years after coronary surgery. The computed tomography (CT) scan showed a 5—6-cm-long bony structure originating from the distal sternum with its tip directed towards the right ventricle (Fig. 1). The structure was resected (Fig. 2) and histopathological examination revealed an exostosis. Fig. 1. 3D CT scan showing impingement of the...
