Abstract

Background: Estimation of stature from bones plays an important role in identifying unknown dead bodies, parts of bodies or skeletal remains. Anthropometric techniques have been commonly used to estimate stature and bone length from these. Various implants are available for the diverse fracture patterns observed in both ends of humerus, which are contoured on the basis of morphometry of the concerned part. The present study focuses on deteremining the total length, mid shaft girth, breadth of distal and proximal ends, maximum transverse diameter of head, maximum vertical diameter of head, breadth of trochlea and capitulum & comparing these parameters between two sides.

Aims :This study focuses on analysing some important bony features of right & left  humerus & compare them.

Materials and Methods: Random collection of 100 dry and processed humerus of both sides, from the skeletal sets of medical students and the Department of Anatomy, IPGME&R, Kolkata were done, by purposive sampling technique. This was a cross-sectional observational study. Dry bones were collected. Un-ossified and diseased bones were excluded from the study. Measurements were taken with the help of osteometric board, electronic digital calliper and measuring tape. Lengths and breadths were measured in millimetres. Data was summarized by routine descriptive statistics. All numerical variables analyzed were normally distributed by Kolmogorov-Smirnoff goodness-of-fit test. Comparison between left and right cohorts was done by Student’s independent samples t test.

Results and Conclusions: Mean total length of the bone was 295.97±19.19mm. Mean value of breadth of proximal & distal ends were  45.53±3.59 mm 56.76±3.69 mm, mid shaft girth 60.28±4.21 mm, maximum transverse & vertical diameter of head were 38.94±2.97 mm & 35.37±3.31mm, breadth of trochlea &  capitulum were 22.88±3.20 mm 16.32±1.63 mm. No significant difference was observed between humeri of two sides. However,this study might be helpful in designing newer prostheses for elbow as well as shoulder replacement surgeries.

Key Words: Morphometry, Humerus, Mid shaft girth, Prostheses, trochlea, capitulum, head.
