ABSTRACT
Background: In forensic analysis, the estimation of the stature is key in identification of an individual. Thestature of an individual can be estimated from long bones especially the tibia and the femur as these have directcorrelation to the height of an individual. The tibia is ideal in this application as it resists erosion and keeps itsanatomical shape for long even after burial. Mechanical loading is especially high in the distal ends of longbones of the lower limb and as such they display significant inter-individual differences. The use of distaldimensions in estimation of the length of the tibia from skeletal remains has not been reported.Materials and methods: 150 dry and processed tibias irrespective of side, grossly normal and complete wererandomly collected from a medical college of south India. Unossified bones, bones with diseases and injurieshave been excluded.Results: In our study, the mean and standard deviation was calculated for each of the dimensions. The resultswere analysed with simple regression analysis. Pearson’s coefficient determined for each parameter andtabulated. Simple linear regression equations were then deduced from the obtained data which would predictthe expected maximum length of the bone from its various other parameters.Conclusion: Simple regression equations are deducted from the obtained data, which would predict the expectedmaximum length of the tibia from its various parameters
ABSTRACT
The purpose of this study was to determine the anatomic parameters of the kidney in adults. The Renal lengths, width at superior and inferior poles, thickness at the superior and inferior poles were measured in 151 adult cadaver kidneys. A digital vernier caliper was used for performing the measurements. The data were statistically analyzed. The mean renal length was 8.9 ± 0.9 cm on the right side and 9.1 ± 0.9 cm on the left side. The mean width of the superior pole of the right kidney was 4.9 ± 0.6 cm and the left kidney was 5 ± 0.7 cm. The width of inferior pole of the right and left kidneys were 4.8 ± 0.6 cm and 4.5 ± 0.7 cm respectively. The mean thickness of the superior pole of the right kidney was 3 ± 0.4 cm and left kidney was 3.2 ± 0.5 cm. The mean thickness of the inferior pole of the right and left kidneys were 3.1 ± 0.4 cm and 3.2 ± 0.5 cm respectively. There was no statistical significance with respect to the length of both the kidneys. However there was some data on width and thickness among the right and left side showed the difference which was significant statistically. The present study has provided additional information on the renal morphometry which will be of use to the surgeons and radiologists.
El propósito de este estudio fue determinar los parámetros anatómicos del riñon en los adultos. La longitud renal, ancho de los polos inferior y superior, y grosor de los polos superior e inferior se midieron en riñones de 151 cadáveres adultos. Se utilizó un caliper vernier digital para realizar las mediciones y los datos fueron analizados estadísticamente. La longitud media renal fue 8,9±0,9 cm en el lado derecho y 9,1±0,9 cm en el lado izquierda. El ancho promedio del polo superior del riñón derecho fue 4,9±0,6 cm y del riñón izquierdo fue 5±0,7 cm. El ancho promedio del polo inferior del lado derecho e izquierdo riñones fueron 4,8±0,6 cm y 4,5±0,7 cm, respectivamente. El grosor promedio del polo superior en el riñón del lado derecho fue 3±0,4 cm y el izquierdo 3,2±0,5 cm. El grosor promedio del polo inferior del riñon del lado derecho e izquierdo fueron 3,1±0,4 cm y 3,2±0,5 cm, respectivamente. No hubo diferencia significativa en relación con la longitud de los riñones. Sin embargo hubo algunos datos en ancho y grosor entre el lado derecho e izquierdo que mostraron diferencia significativa. El presente estudio ha proporcionado información adicional sobre la morfometría renal que puede ser de utilidad para los cirujanos y radiólogos.
