| description | Introduction: Reconstruction of stature from human
skeletal remains has long been considered as an important
medico legal challenge. In absence of other bones like
cranium or pelvis, anatomical knowledge of long bone
even when only a fragment of it becomes available may
help to meet that challenge through a series of estimation
of length of long bone first and then reconstruction of
stature of the unidentified individual.
Aim: To determine length of different segments of humerus
and then reconstruction of total length of humerus, in West
Bengal population using standard regression formula.
Materials and Methods: A total of 60 adult dry humerii, 30
belonging to right and 30 of left side of unknown age and
sex were taken. Each bone was divided into five segments
(H1, H2, H3, H4 and H5) by taking predetermined points on
it. Such five parameters along with total length of humerus
were measured to the nearest millimetre. The values were
presented as mean±SD in mm separately for each side.
The proportion of each segment to the total length was
also calculated. Simple linear regression (p < 0.01) was
used to correlate the length of each segment with total
length. Later on, when multiple regressions were used to
estimate total length, incorporation of variables was made
through stepwise regression.
Results: The average total length of humerus on right
side was 307.13±17.99 and on left side 297.77±19.78. The
mean lengths of five segments, namely H1, H2, H3, H4 and
H5 were 6.11±0.80, 34.07±1.44, 18.76±2.00, 16.22±2.13
and 32.51±2.70 mm on right and 6.03±0.73, 33.10±1.95,
18.12±1.68, 15.99±1.82 and 31.96±1.32 mm on left humerii
respectively. When multiple linear regression was used,
H2 alone contributing 65% and 76% showed significant
changes in estimating total length of humerus in case of
right and left sides respectively.
Conclusion: The present study revealed prediction of total
length of humerus from detailed estimation of different
segments of humerus among West Bengal population
which may be treated in future as an useful reference not
only for anatomists, forensic experts and archaeologists but
also for orthopaedic surgeons undertaking reconstructive
surgery for proximal and distal humeral fractures. |
