ABSTRACT
This cross-sectional descriptive purposive study was conducted among 150 (70 right and 80 left) fully ossified dry human scapulae of Bangladeshi people from January 2019 to December 2019 in the Department of Anatomy, Mymensingh Medical College, Mymensingh. Shape of the glenoid cavity was observed as pear, oval or inverted comma shape. Morphometric parameters such as length and breadth of glenoid cavity were measured by digital Vernier slide calipers. In this study, 19.13% cases were found inverted comma shaped, 35.65% cases were oval and 45.22% cases were pear shaped. The mean±SD length of glenoid cavity was 37.5±3.61 mm and 36.19±3.68 mm on right and left sided scapulae respectively and mean±SD breadth was 23.6±2.73 mm on right and 23.42±2.75 mm on left side respectively. Mean±SD glenoid cavity index was 62.89±4.39 on right and 64.61±4.74 on left sided scapulae. Morphometric analysis of glenoid fossa of scapula might help clinicians in shoulder and its associated diseases.

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.

Humerus is the largest bone of upper limb. Upper limb is the most movable part and main working tools of human body. This is a cross sectional, analytic type of study carried out in the department of Anatomy, Sir Salimullah Medical College (SSMC), Dhaka from July 2011 to Dec 2012. The present study was performed on two hundred (n=200; male=117 & female=83) left sided fully ossified dry humerus bones collected from Department of Anatomy and the medical students of 1st and 2nd year MBBS course of Sir Salimullah Medical College (SSMC), Dhaka and Dhaka National Medical College (DNMC), Dhaka. Morphometric study was carried out on all samples by direct physical method. There was statistically significant difference (p=0.001) between male and female bone in the diameter of the head and shaft of the left humerus. The present study was attempted to provide a morphometric base line data of fully ossified human left humerus.
