Estimation of total length of humerus from its segments

Abstract

The aim of the present study was to calculate the total length of the humerus from its segments using linear, transverse and sagittal measures. One hundred and fifty dry adult unpaired humeri of both sides and of unknown sex from South India were studied. The humeri were divided into eight segments using salient bony points and muscular markings. The length of each segment was compared with the total length. These were subjected to statistical analysis. A high degree of correlation was found between segment length and total length and hence regression equations were calculated to estimate total length of humerus from each segment. The difference in measurements of the right and left sides was insignificant; hence single equations were calculated for all 150 bones. The length of the humerus and finally the stature of the individual could be calculated fairly accurately with an error of less than 2 cm. The results were compared with similar studies on other Indian populations. Calculation of total length from longer segments is comparable with other Indian populations, but if only shorter segments are available, new equations are needed for each population.

Method of Estimation of Total Length of Femur Bone From Its Longitudinal Segmental measurements and Midshaft Circumference in Nepalese Population.

“…This is in accordance with the previous study results which conclude that there was no statistically significant difference between measurements of two-sided femur bones [14][15][16][17]. This study also differs from the previous studies on the ground of choosing the bony landmarks for the segmental measurements which make it possible to estimate the femoral height in large perspective.…”

“…The previous studies also had provided series of the regression equation for the estimation of stature from the measurements of long bones and cadaveric height [1,11,12]. Many studies are done for estimating the total femoral height and hence stature of the individual around the world, some of key works were done by Steel and McKern [13] among 101 dry femora of both sexes, by Bidmos among indigenous South African and South African of European descents [3], by Chandran and Kumar among 60 adult femur in Chennai, India [10], by Genovés among 235 cadavers from Mexico [5], by Sing et al among 200 femur bone of both sexes in Bhopal India [14] and by Solan [8] among 150 dry femora of South Indian populations and by Mukhopadhyay et al among Indian Bengali male [15].…”

Anatomic fit of precontoured extra-articular distal humeral locking plates: a cadaveric study

“…Distal humeral width was the most relevant measure, and it had approximately twice the R 2 value of humerus length. In a previous cadaveric humeral estimation study, the R 2 between the distance from the olecranon fossa upper margin to the trochlear tip and humeral length was 0.47 [17]. This R 2 suggests that humeral length is not highly predictive of the size of the distal humeral region.…”

Humeral Morphometrics: A Study in Eastern Indian Population

“…In some previous studies conducted in India and abroad, right -left asymmetry could not be established [4,17]. On the contrary, some studies noted the asymmetry in different morphometric measurements between two sides [11,13,18].…”
