A Morphometric Study of Glenoid Cavity of Scapula in Bangladeshi Population.

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.

Study of Nutrient Foramina of Dry Adult Human Clavicle.

As a modified long bone, the clavicle is most important bone for transmission of body weight from upper limb to the axial skeleton, for attachment of muscles and is a significant source of bone grafting. This descriptive cross-sectional study was conducted among 150 (65 right and 85 left) fully ossified dry human clavicle in Mymensingh Medical College, Mymensingh, Bangladesh from January 2020 to December 2020. Sample was collected by the help of nonrandom purposive sampling technique from Anatomy department of Mymensingh Medical College and Community Based Medical College, Bangladesh, Mymensingh. In this study, nutrient foramen was present in 86.67% (130) cases. On the right side, 87.69% (57) cases and on the left side, 85.88% (73) cases were found present. Out of 130 clavicles where nutrient foramen were present, 52.31% (68) nutrient foramina were on inferior surface, 46.92% (61) on posterior surface and 0.77% (1) on superior surface. On the right side, 49.12% (28) cases were found on inferior surface and 49.12% (28) were on posterior surface and remaining 1.75% (1) was on superior surface. On the left side, 54.79% (40) cases were found on inferior surface and 45.21% were on posterior surface whereas none was found on superior surface. Among the present 130 cases, 1 nutrient foramen was found in total 80% (104) cases and 2 in 20% (26) cases. In right side, the numbers of cases were 75.44% (43) for 1 and 24.56% (14) for 2 nutrient foramina. In left side, the number of cases of 1 was 83.56% (61) and 16.44% (12) for 2 foramina. The nutrient foraminal direction was 98.46% (128) towards acromial end and 1.54% (2) to sternal end. In the right side, the direction was 100% (57) towards acromial end. In the left side, the direction was 97.26% (71) towards acromial end and 2.74% (2) to sternal end. In the current study, the mean ±SD nutrient foramina of 65 clavicles of right side were 71.04±13.91 and 67.13±16.30 in 85 left sided clavicles. The purpose for undertaking this study was to obtain baseline data on nutrient foramen to help to predict the success rate and different surgical interventions regarding fractures and grafting.

Variation of Acromiocoracoid and Acromioglenoid Distance in Bangladeshi People.

This cross-sectional descriptive purposive study was done on 150 (70 right and 80 left) fully ossified dry human scapulae of Bangladeshi people to find out the variation in length of acromiocoracoid and acromioglenoid distance. Sample collection was carried out in the Department of Anatomy, Mymensingh Medical College, Bangladesh from January to December 2019. Any kind of damaged or broken scapulae were excluded to maintain standard measurement. Length of these distances was measured with the help of digital Vernier slide calipers. The mean±SD acromiocoracoid distance were 35.8±4.64 mm and 36.32±5.55 mm on right and left sided scapulae respectively and the mean±SD acromioglenoid distance were 27.69±3.43 mm on right sided scapulae and 28.18±3.26 mm on left sided scapulae. These data are important to compare Bangladeshi scapulae to those from various other races that could contribute to demographic studies of shoulder disease probability and management in Bangladeshi population.

Variation of Mid shaft Antero-posterior and Transverse Diameter of Femur in Bangladeshi People.

Femoral morphometric variation is a dynamic system for different region, which is influenced by geographical, physiological and environmental factors, due to the adaptation, functional and remodeling responses of bones. This descriptive cross-sectional study was conducted on 150 (64 right and 86 left) fully ossified dry human femur of Bangladeshi people to find out the variation of mid shaft antero-posterior and transverse diameter of femur. Sample was collected in the Department of Anatomy, Mymensingh Medical College (MMC), Bangladesh from January 2019 to December 2019. All samples were assessed to eliminate fractured, pathologically damaged and remodeled bones. The diameters were measured with the help of digital Vernier slide calipers. The mean±SD mid shaft antero-posterior diameter of right and left femur were 25.03±2.86 mm and 25.54±2.65mm respectively. The mean±SD transverse diameter of right and left femur was 24.24±2.43mm and 24.54±2.38mm respectively. The knowledge of variations in the parameters of dry femora will help the orthopedicians for the treatment and management of femoral shaft fracture. These data also provide information about mid shaft diameter of femur of Bangladeshi people and to compare these data to those from various other races. Thus it could contribute for the design of well-fitting prosthesis which suits the Bangladeshi population. This value may be considered while making a best-fit femoral prosthesis.
