“…SI appears to be higher on the right side than left side; however, this finding does not have any statistical significance. Although our data are similar to results obtained by El-din and Ali (2015) [13], Chhabra et al (2015) [14] and Vaishnani et al (2018) [15], these data are higher than results of other researchers. Furthermore, SI was detected higher in males when compared with females in our study.…”

Background: The glenoid cavity is a sliced egg-shaped joint surface located on the lateral margin of the scapula to form the shoulder joint. Antero-superior notch affects the morphology of the glenoid cavity. Recognition of variations in shape and dimensions of the glenoid cavity is important for better comprehension of joint-associated diseases, especially in total shoulder arthroplasty procedures. The aim of this study was to perform morphometric measurements on the glenoid cavity through Multi-detector Computed Tomography images. Methods: Glenoid cavities of 391 individuals (197 males (50.4%), 194 females (49.6%)) were reviewed by using Multi-detector Computed Tomography. CT images were examined from January 2014 to April 2016 by scanning files. The average age of men was 60.28 ± 15.43, while the average age of women was 58.82 ± 16.38. The maximum length and maximum width of glenoid cavities, the width, depth and circumference at the notch level were measured, and the index value was calculated. The glenoid cavity shapes were typed as pear, inverted comma and oval type. Furthermore, metric values which provide the best differentiation between genders were found through ROC analysis. Results: The pear GC type was detected by 53.2%, inverted comma type was detected by 28.4%, and oval type was detected by 18.4%. In all of our morphometric measurements, male values were higher than female values, and there was no significant difference between them. Furthermore, significant differences were found for width at the notch level and circumference lengths between the right and left sides; however, there was not any significant difference between maximum length, maximum width, depth and the index (p<0.05). Results of ROC analysis revealed significant measurements for the maximum length and maximum width measurements of the glenoid for gender determination. Conclusions: It was reported in the literature that morphometric information of the glenoid cavity is useful to increase clinical success in case of different pathological conditions such as Bankart lesion, rotator cuff disease, and osteochondral defect. Recognition of different shapes and dimensions of the glenoid cavity is essential for the design of the glenoid component especially for total shoulder arthroplasty procedure. We

“…The morphological variations are very commonly seen in the glenoid cavity which is regarded as the head of the scapula and articulates with the head of the humerus at the glenohumeral joint [14]. Morphological variants of the glenoid like alterations in size, shape or any projections are associated with functional muscle-bone unit& may affect glenohumeral instability [15].…”

“…The presence of the notch in the anterior margin part of the glenoid rim has a great role to determine the morphology of glenoid cavity [5,8]. The shoulder joint is not only one of the most frequently dislocated joint of the body but also dislocation along with the fracture of glenoid cavity which is quite common [3,10] [11]in North Indians andVaishnani et al [14] in Gujarati population.But to the best of our knowledge, our study conducted on the highest number of dry bones that is 260 scapulae. Apart from that, like Prescher et al [5] we have also applied the same method to determine the shape of the glenoid process.So, it is expected that, the authentication of our results will be high as compared to other studies.…”

The purpose of this present study was to observe the morphological variations of glenoid process of adult human scapulae by subjective evaluation, because morphologic variants of adult glenoid process play an important role in various shoulder joint pathologies especially dislocations with fractures of the glenoid cavity which is also quite common.Materialsand Methods: Two hundred sixty adult dry scapulae (127 right & 133 left) from the osteology museum of department of Anatomy, belonging to Indian population of unknown sex & age were obtained for the morphologic pattern of glenoid cavity by subjective evaluation. We have examined the presence of notch in the glenoid process of each scapulae& according to the presence of notch, we evaluated the bones for the morphological classification as pear; inverted comma & oval shaped glenoid process. Our observations were compared with other osteological studies performed on different other population groups.Results: Out of total 260 scapulae, 187 bones showed notch in the margin of the glenoid cavity.Most of the bones without a notch were termed as oval shaped (73 scapulae) glenoid & rest of the bones were of pear shaped variety. Among the pear shaped glenoid, 113 scapulae showed pear shaped cavity with slight notch; 71 scapulae showed an inverted comma shaped glenoid. Not only the basic morphology, we have also reported some of the scapulae with special morphologic features like a very prominent infraglenoid tubercle; presence of foramen in the glenoid cavity &highly special nodular glenoid cavity.Conclusions: Though glenoid cavities showed highly variable morphological pictures, but the clinicians should be well versed with the normal appearance & anatomic variants of glenoid cavities on dry bones, so that they can interpret its morphology on radiographs and MRI scans. Our results of this subjective evaluation may be of help as baseline data for theclinicians especially for the orthopaedic surgeons for the diagnosis &treatment modalities of shoulder dislocations & fracture.

“…The glenoid cavity (GC), which is the upper end of the lateral border of the scapula, articulates with the head of the humerus (1). The articular surface of the GC is covered with hyaline cartilage and the borders of the joint surface are the attachment points for the glenoid labrum (2). The glenoid labrum is a fibrocartilaginous structure and increases the depth of the articular surface (3).…”

Aim: The aim of this study was to determine the notch and shape variations of the glenoid cavity (GC), to emphasize its clinical importance, and compare it with the previous studies. Material and Methods: This study was performed with 157 (78 right sides, 79 left sides) adult Anatolian dry scapulae. The GCs were typed as oval, pear, and inverted comma shaped and noted the number of GC notch. Results: The most common GC shape was found as the pear shaped with 63 (80.8%) at the right side, 49 (62%) at the left side, and 112 (71.4%) in total. The second most common GC shape was found as oval shaped with 13 (16.6%) at the right side, 28 (35.5%) at the left side, and 41 (26.1%) in total. The glenoid notch was found at the right side, left side, and totally; 28 (35.9%), 19 (24.1%), and 47 (29.9%), respectively. All of the inverted comma shaped GCs had distinct glenoid notch, while the oval shaped GCs not. The pear shaped GCs had indistinct glenoid notch or no glenoid notch. The glenoid notch was found at the right side, left side, and totally on the pear shaped GC; 26 (41.3%), 17 (34.7%), and 43 (38.4%), respectively. Conclusion: Pear shaped GC was found as the most (71.4%) common shape in this study. Forty-seven (29.9%) of the scapulae had a glenoid notch. The notch and shape variations of the GC are important and this study will contribute to anatomists, orthopedists, and radiologists from this perspective.
