Learning Curve in Surgical Treatment of Odontoid Fixation for a Series of Type II C2 Fractures

2019

The craniovertebral junction (CVJ) is a complex anatomical area upon which most of the motion of the upper cervical spine depends [1]. Because of its unique range of motion, the CVJ is subject to several types of traumatic injury; it has been shown that odontoid fractures are the most common ones in the general population and are the most common isolated spinal fractures [2]. Accounting for up to 18% of all cervical fractures, odontoid fractures are the most common ones in elderly patients [3], in whom they account for up to 60% of spinal cord injuries [4].

Tailoring the excitation of fundamental flexural guide waves in coated bone by phase-delayed array: Two-dimensional simulations

2015

The fundamental flexural guided wave (FFGW) enables ultrasonic assessment of cortical bone thickness. In vivo, it is challenging to detect this mode, as its power ratio with respect to disturbing ultrasound is reduced by soft tissue covering the bone. A phase-delayed ultrasound source is proposed to tailor the FFGW excitation in order to improve its power ratio. This situation is analyzed by 2D finite-element simulations. The soft tissue coating (7-mm thick) was simulated as a fluid covering an elastic plate (bone, 2–6 mm thick). A six-element array of emitters on top of the coating was excited by 50-kHz tone bursts so that each emitter was appropriately delayed from the previous one. Respo…

Reconstruction of human subsistence and husbandry strategies from the Iberian Early Neolithic: A stable isotope approach

2018

Objectives The Early Neolithic involved an important social and economic shift that can be tested not only with the material culture, but also through biomolecular approaches. The Iberian Peninsula presents few Early Neolithic sites where fauna and humans can be analyzed together from an isotopic perspective. Here we present an isotopic study on the site of Cueva de Chaves as an example for understanding the dietary and economical changes that took place during Early Neolithic in Iberia. Material and methods Here we apply carbon and nitrogen stable isotope analysis to bone collagen from 4 humans and 64 faunal samples from 14 different species. The large dataset belongs to the same unique ch…

Distinguishing between Bos and Bison petrous bones. A case study: Bovines from the des-cubierta cave (Pinilla del Valle, Madrid)

Źródła archeologiczne z cmentarzysk jako narzędzie badawcze do poznania stanu zdrowia ludzi okresu średniowiecza, na podstawie stanowiska nr 1 w Bycz…

2019

Research on early medieval and medieval archaeoiogical and anthropological cemeteries is not the easiest. Archaeoiogical and anthropological research in Byczyna showed how valuable e data from cemetery research is, how much we can leam about the community living in medieval cities. Analyzing bone material at the preliminary stage of research, it can beseen that the health condition of the inhabitants of medieval Byczyna was not good. Almost half of the examined skeletons have traces of various diseases, especially degenerative diseases and injuries. There were also cases of conditions that indicate that the diet of the dead did not have basie nutrients.

A reappraisal of the purported gastric pellet with Pterosaurian bones from the Upper Triassic of Italy

2015

A small accumulation of bones from the Norian (Upper Triassic) of the Seazza Brook Valley (Carnic Prealps, Northern Italy) was originally (1989) identified as a gastric pellet made of pterosaur skeletal elements. The specimen has been reported in literature as one of the very few cases of gastric ejecta containing pterosaur bones since then. However, the detailed analysis of the bones preserved in the pellet, their study by X-ray microCT, and the comparison with those of basal pterosaurs do not support a referral to the Pterosauria. Comparison with the osteology of a large sample of Middle-Late Triassic reptiles shows some affinity with the protorosaurians, mainly with Langobardisaurus pand…
