A Morphometric study on adult dry Humerus

Abstract

Background: Fractures of long bones are not uncommon in the modern era due to changes in lifestyle and dependency on machinery. The blood supply of long bones plays an important role in the healing of fractures. Long bones derive their blood supply through the nutrient, periosteal, metaphyseal, and epiphyseal arteries. Though much advancement in science has been done, but estimating the stature of the individual from bones and as well as reconstructions of life from the human skeletal still remains a challenge for many anthropologists and forensic experts. Statures estimated from the human skeletal remains is an important step in assessing health and general body size trends among the given populations and also have an important role in the identification of missing persons in to medico-legal investigations. Present study conducted to find morphometric analysis.
Materials and Methods: The present study was conducted with 120 dry adult human humeri. We have used anthropometric board for measurement and digital vernier clippers. Each bone was studied for the humerus segmental morphometric analysis. We have measured following measurements.  Maximum length of humerus, Mean distances between the articular segment of the humeral head and the greater tuberosity of humerus, Mean distance between caput humerus and callum of humerus, Mean distance between proximal and distal point of olecrane of humerus, Mean distance between distal part of olecrane process and trochlea of humerus, Mean distance between proximal edge of olacrane fossa and proximal part of trochea of humerus.
Results: We found, maximum length of humerus was 302.6±28.2mm on right and left was 301.16±26.4mm. The mean distances between caput humerus and callum anatomicum was 41.1±5.9mm on right and 41.6±7.2mm on left. The mean distances between proximal and distal point of olecrane fossa was 39.6±1.2mm on right and 40.3±2.8mm on left. The mean distances between distal part of olecrane process and trochlea of humerus was 22.6±2.6mm on right and 23.4±1.8mm on left.
Conclusion: In conclusion, morphometric analysis suggests that there are some differences between the segments of humerus within different population groups. The present study finding may be helpful to forensic experts and anthropologists.
