Jcl:ICR pregnant mice were immobilized for 120 minutes from days 8-12 of gestation, and their fetuses were examined for skeletal features on day 18 of gestation. In the stressed group, decreased maternal bodyweight gain and lower fetal weight were noted. In this group, the incidences of segmentation defects, fused ribs, absent lumbar vertebrae and full supernumerary ribs were increased in fetus...

The histology of cervical ribs of Sauropoda reveals a primary bone tissue, which largely consists of longitudinally oriented mineralized collagen fibres, essentially the same tissue as found in ossified tendons. The absence of regular periosteal bone and the dominance of longitudinal fibres contradict the ventral bracing hypothesis (VBH) postulated for sauropod necks. The VBH predicts histologi...

The search for improved femoral fixation in cemented total hip arthroplasty is ongoing. Two design variables, surface finish and stem contour, were evaluated. Sixteen titanium femoral stems of one design were cemented into fiberglass femora. One half of the components had a polished surface and the rest had a roughened finish. Within each group, 4 stems had vertically oriented ribs on the proxi...

Postcranial remains of Boreogomphodon from the Upper Triassic of North Carolina are described and compared to those of other known traversodontid cynodonts. The postcranial skeleton of Boreogomphodon is characterized by four sacral ribs, simple ribs lacking costal plates, the extension of the scapular neck below the acromion process, a short scapular facet on the procoracoid, a concave anterior...

into the 1st Surgeon's Ward of the Medical College Hospital on the 25th March, 1866, at 9 p. m., with fractured ribs ; the fracture extending from the apex of the left axilla, downwards and forwards, to the margin of the costal cartilages, below the left nipple, involving therefore all the ribs situated in that line, i. e., from the third to the eighth vib. There was emphysema of the left side ...

The following are physical signs which can be elicited in patients with chronic airways obstruction: a reduction in the length of the trachea palpable above the sternal notch; tracheal descent with inspiration; excessive use of the scalene and sternomastoid muscles; excavation of the suprasternal and supraclavicular fossae during inspiration; jugular venous filling during expiration; loss of bu...

Lumbo-costo-vertebral syndrome, which includes abnormalities of the vertebral bodies, ribs and trunk musculature, is very rare and only few cases have been reported. We report a case of 18-month-old female child with absent ribs, hemivertebrae, superior lumbar hernia (features of lumbo-costo-vertebral syndrome) and posterior spinal dysraphism, which to our knowledge is the first case in the Eng...
