title: Morphometric Study of Nutrient Foramen in Adult Human Dry Left Humerus.
abstract: The major blood supply to long bones occurs through the nutrient arteries, which enter through the nutrient foramen. The supply of nutrient artery starts during the early phases of ossification. It is essential in operative procedures such as bone graft, tumour resection, trauma healing and bone transplant techniques both in orthopedics and micro vascular surgery. The present study is an observational analytic type of study which was performed on two hundred (n=200; male=117 & female=83) left sided dry humerus bones. In this present study the majority of the bones had a single nutrient foramen which may represent a single source of blood supply. The location of the nutrient foramen is predominant on the antero-medial aspect of humerus. The position of the nutrient foramen is predominant on the middle 1/5th of the shaft humerus. There was no significant difference (p=0.319) in presence, absence, number, location and position of nutrient foramen in male and female left human humerus. This study and recorded data may help in surgical procedures in orthopedics and in micro vascular surgery.
