Abstract

Objective The morphology and quantitative anatomy of the axis vertebra (C2) attracts a lot of attention between anatomists, surgeons and radiologists. However, no report exists in the literature correlating the height of the dens with the length of the femur. Our paper aims to determine such a correlation. Material and methods An examination of forty-five adult dry skeletons (twenty-three male and twenty-two female) was conducted. The height of the odontoid process of the axis and the maximum length of the femur were measured and statistically analyzed. Results The mean values for the height of the dens were 19.13±2.74 mm and 16.83±2.45 mm concerning the male and female dry skeletons respectively. The mean maximum length of the right femur bone was 43.04±2.32 cm for male and 39.90±2.40 cm for female skeletons. Data analysis revealed a statistically significant correlation (r=0.709, p

2. Osteogenesis Imperfecta Type II.

Author

Bader, Birgit and Warner, Roger W.

Abstract

Osteogenesis imperfecta (OI) type II is a form of skeletal dysplasia which results in poor skeletal ossification and multiple long bone and rib fractures. The following cases illustrate the sonographic appearances of fetuses afflicted with OI type II. The etiology of OI, suggested scanning techniques, and differential diagnosis for skeletal dysplasia are discussed. [ABSTRACT FROM PUBLISHER]

However, no report exists in the literature correlating the height of the dens with the length of the femur. Our paper aims to determine such a correlation. Material and methods An examination of forty-five adult dry skeletons (twenty-three male and twenty-two female) was conducted. The height of the odontoid process of the axis and the maximum length of the femur were measured and statistically analyzed. Results The mean values for the height of the dens were 19.13±2.74 mm and 16.83±2.45 mm concerning the male and female dry skeletons respectively. The mean maximum length of the right femur bone was 43.04±2.32 cm for male and 39.90±2.40 cm for female skeletons. Data analysis revealed a statistically significant correlation (r=0.709, p <0.001) between the height of the odontoid process and the maximum length of the femur bone. A linear regression model expressing this association was created: Femur max length (in cm) = 32.874 + 0.531 x Dens height (in mm). Conclusion We present a new mathematical equation correlating one of the most studied long bones of the skeleton, the femur, with another "long" part of the bony structure of the human body- the C2 odontoid process., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2020, Vasilopoulos et al.)

Abstract

The total length (TL) and length of the ossified part (OL) of some long bones of the upper (humerus, ulna, radius) and lower limb (femur, tibia, fibula) were evaluated in 58 aborted human fetuses (crown-rump length, CRL, between 38 and 116 mm, developmental age from 8 to 14 weeks). The specimens, without any detectable malformation, were cleared and double-stained with alcian blue and alizarin red S to obtain a differential detection of the ossified part within the comprehensive outline between the cartilaginous epiphyses. The correlation between the values of TL and OL and those of CRL emphasized that the systematic OL measurement in limb long bones correlated better than TL with development age, since OL increased faster than TL. TL and OL also correlated with the CRL by bivariate allometry (ln y = ln a + b ln x) and the data obtained showed that they grew with positive allometry. The comparison between the cumulative values of the bones examined in each limb showed that both TL and OL grew relatively faster in the lower limb than the upper; the greatest growth rate was found for OL in the lower limb. These results many provide a tool for a comprehensive assessment of long bone growth patterns and may be useful in determining fetal growth even in incomplete specimens, in which one or some long bones can still be measured.
