Millions of Americans are affected by spine diseases, with approximately 40 percent of all spinal fusion surgery performed for cervical spinal fusion. Some 230,000 patients are candidates for spinal fusion, with the numbers of potential patients increasing by 2 to 3 percent each year as the nation...

the first descriptions of xenarthrans, intermediate vertebral conditions remain unknown in the fossil record, and uncertainty remains regarding the development of the involved articulations. We used developmental and morphological techniques to provide a novel developmental perspective on the evolution of xen...
The same Tornieria vertebra in dorsolateral oblique view, showing some pneumatic features on the lateral aspect of the neural spine. The pocks on the centrum are also raising my pneumaticity antennae, but I can’t be sure from my limited set of 16-year-old photos. When Diplodocus caudals ...
Vertebral formulae, the combination of regional numbers of vertebrae making up the bony spine, vary across vertebrates and within hominoid primates. Reconstructing the ancestral vertebral formulae throughout hominoid evolution has proved a challenge due to limited fossil evidence and disagreement among ...
The average number of abdominal vertebrae turns out to be the lowest in fish with low fecundity. A group of low-fecundity fish is also identified when comparing the average relative fecundity in females with different numbers of vertebrae in the spine. Individuals with 17 abdominal vertebrae have...
LSTV was found in 25.1% of the cohort. It is important to ascertain atypical vertebrae variations rather than the absolute number of vertebrae because variants such as 7C11T6L and 7C13T4L may still have typical numbers of vertebrae in total. However, due to the differences in the number ...
