Abstract Background and aims: Glenoid cavity of scapula is known for its variable morphology. The variations in the shape of glenoid cavity are due to the presence of a notch in its antero-superior part. The glenoid cavity is small and allows only a limited area for fixation devices. Knowledge of its morphology and dimensions would help in designing shoulder prosthesis for shoulder arthroplasty. Aim of current study is to determine the metrical and morphological variations [variation of shapes] of the glenoid cavity of the scapula for a better understanding and management of shoulder pathology. Materials and Method: One hundred dry scapulae of unknown sex availed from the Department of Anatomy, Mysore Medical College were studied. Varying shape of glenoid cavity based on presence of notch was also noted and measurements were taken with the digital Vernier caliper. Results: The glenoid cavity was found to occur in pear, oval, inverted comma shapes in frequency of 65.3%, 28.8%, 5.7% on right side and 62.2%, 27%, 10% on left side respectively. The mean anteroposterior diameter 1 and 2 were 24.05 ± 2.79 mm and 18.31 ± 2.36mm respectively. The mean Glenoid cavity index was 68.05 ± 4.87mm. Conclusion: The findings of the present study concurs with other studies, although there is slight difference in frequency of occurrence of shape of glenoid cavity which could be explained on the basis of ethnic and racial basis. The sound knowledge of various parameters of the glenoid cavity is important while performing shoulder arthroplasty and designing glenoid prostheses

Abstract Background and aims: Suprascapular nerve may be compressed anywhere along its course but most commonly at the level of SSN (suprascapular notch) and spinoglenoid notch. The variation in the morphological and morphometric features of SSN, spinoglenoid notch, therefore plays a crucial role in the suprascapular nerve entrapment syndrome. The purpose of present study was to determine the variation in morphology and dimensions of SSN and to determine posterosuperior and posterior limits of safe zone for shoulder joint procedures from posterior approach. Material & methods: We conducted study on 134 dry scapulae of north Karnataka region and classified the SSN into various shapes according to Iqbal et al and I-VI types based on description by Natsis et al, along with this, the mean distance from the SSN to supraglenoid tubercle and the mean distance between posterior rim of glenoid cavity and medial wall of spinoglenoid notch at the base of scapular spine were also measured. Results: Based on Iqbal et al classification, 'U' shaped notch found to be most common (35%) whereas least common was W shaped (0.7%).The incidence of complete ossification of STSL was 12.6%. Based on Natsis classification most common was type II (TD>VL) seen in 69% and least common was type VI (notch & foramen) 0% .The mean distance from SSN to supraglenoid tubercle was 27.3 mms ± 1.7 and mean distance between posterior rim of glenoid cavity and medial wall of spinoglenoid notch at the base of scapular spine was 13mms ± 0.2 which are comparatively less than the other population studies which are mentioned in the article. Conclusions: There are variations in the shape and size of SSN and safe zone critical distance in different populations so it requires still more population specific studies on suprascapular notch.

Back ground: Humerus is the longest of the long bones of superior extremity.It”s head articulates with scapular glenoid cavity to form the gleno-humeral/Shoulder joint.The rounded head of Humerus is too weakly supported in the scapular glenoid cavity lined by glenoid labrum which makes it the most mobile and most unstable nd joint and so most commonly dislocated joint of the human body.Also the humeral head part is the 2 most important part of shoulder arthroplasty. Aim of the study is to make a clinical evaluation of parameters used in prosthesis design for the humeral component applied in arthroplasty of the proximal upper extremity. Methods: A total of 100 (Rt -58,Lt –42 ) dry human Humerus available in the Department of Anatomy of Calcutta National Medical College,Kolkata,West Bengal and Nilratan Sircar Medical College,Kolkata,West Bengal were taken for the study.The Humeral heads are measured in supero-inferior(SI) diameter, and antero-posterior diameter(AP), The width of Humeral head (Wdth),and angle of Humeral Torsion were measured. At the very beginning the both sided Humerus taken for the study are properly numbered using permanent marker pen.The width of the Humeral head(Wdth) is measured 1stly by pressing the head in modelling dough and when the mould is prepared,semisolid plaster of paris is lled into the mould. After drying the replica of humeral head is smoothened upto the mark of anatomical neck of humerus thus proper width can be measured. The superoinferior(SI) diameter, and antero-posterior diameter(AP) were measured by digital slide callipers by placing it directly onto the surface of consequently numbered humeral heads. The width of Humeral head (Wdth ) were measured from these replica(properly numbered) humeral heads, made of plaster of paris at the middle, the highest thickness was measured. The measurements are taken via spreading slide calipers in milimeters. For measuring the angle of humeral angle of torsion ,we xedly placed the humerus on to a area over the smooth part of the vertical wall which was meeting another horizontal wall at 90 degrees angle thus the line joining the two epicondyles of humerus lies parallel to the vertical wall.Now placing the straight edge of the protractor onto the upper end of humerus the angle of humeral torsion is measured. Results: Both sided Humerae were analysed separately for Morphological measurement, and angle of Humeral torsion.Mean values for SI were 41.31+3.46mm (Right side) and 40.91+3.27mm(Left side). Mean values for AP were 38.27+3.05mm (Right side) and 37.91+2.70mm(Left side). Conclusion: This study will contribute some relevant data and help the orthopaeditians in dealing with cases of shoulder pathology and shoulder arthroplasty cases.

Introduction: The psoas group of muscles belongs to the posterior abdominal wall. The psoas minor is an inconstant, vestigial, fusiform, slender muscle. Researchers have frequently paid attention to the anatomy, morphology, frequency, of this muscle and its clinical, racial, ethnic correlation. Aim: To investigate and study the psoas minor muscle, with regard to its frequency, agenesis, origin, insertion, morphological variations, its embryological basis and clinical significance. Materials and Methods: The present observational study was conducted at Lady Hardinge Medical College, New Delhi, between December 2018 to May 2019 in the Department of Anatomy. Nine cadavers were studied during routine dissection of the posterior abdominal wall (three females and six males). The prevalence, morphology, morphometry, laterality, sexual dimorphism for psoas minor muscle was assessed. The mean, standard deviation and coefficient of variation of the morphometric parameters were also evaluated. Results: Psoas minor muscle was present in 55.55% (5/9) cadavers. The muscle was bilateral in 22.22% (2/9) cases and unilateral in 33.33% (3/9) cases. In all the cases, the muscle took origin from the T12-L1 vertebra and the intervertebral disc. However, the muscle showed a variation in its distal attachment in one of the cadavers. The muscle was unilateral in both the female cadavers and bilateral in two male cadavers. Conclusion: The prevalence was found to be 55.55%. Knowledge about the incidence of psoas minor muscle is of significant academic interest to anatomists as well as clinicians, for diagnostic purposes (particularly in abdominal pain) and during radiographic imaging.

Pathological changes in the prostate gland occur commonly with advancing age including inflammation, atrophy, hyperplasia and carcinoma and a change in volume is also evident. Estimation of volume of prostate may be useful in a variety of clinical settings. A cross-sectional descriptive study was designed to see the changes in volume of the prostate with advancing age and done in the Department of Anatomy, Dhaka Medical College, Dhaka from August 2006 to June 2007. The study was performed on 70 post-mortem human prostates collected from the unclaimed dead bodies that were under examination in the Department of Forensic Medicine, Dhaka Medical College, Dhaka. The samples were divided into three age groups; group A (10-20 years), group B (21-40 years) and group C (41-70 years). Volume of the sample was measured by using the ellipsoid formula. The mean ± SD volume of prostate was 7.68 ± 3.64 cm3 in group A, 10.61 ± 3.99 cm3 in group B and 15.40 ± 6.31 cm3 in group C. Mean difference in volume between group A and group C, group B and group C were statistically significant (p<0.001). Statistically significant positive correlation was found between age and volume of prostate (r = + 0.579, p < 0.001). Key Words: Prostate; volume; Bangladeshi. DOI: 10.3329/imcj.v4i2.6501Ibrahim Med.
