“…Measurements of the scapular height and width or the inferior angle reported in literature [7,23] are very close to ours (Table 4). Glenoid height and width which are very important clinical parameters have been studied by many authors (Table 4) with diVerent techniques such as direct or X-rays measures [9,10,17,18,23].…”

“…They used CT scans with a slice thickness of 1 mm and found that glenoid version angles obtained from the 3D reconstructions were within 1.0° § 0.7° from the direct measurement, glenoid width was within 1.8 § 1.2 mm and glenoid length was within 1.4 § 1.1 mm. Bryce [7] compared measurements from 3D CT reconstructions and direct measurements made on 40 in situ scapulae. They used CT scans with a slice thickness of 3 mm and glenoid dimensions were manually determined.…”

“…With classical measurement methods, glenoid width varies from 23.6 to 28.6 mm and glenoid height from 32.6 to 36.4 mm. Two papers reported glenoid dimensions from 3D CT reconstructions [7,16] ( Table 4). Our results are very close to Kwon's who used an outlining of the glenoid rim to calculate glenoid dimensions [16].…”

Parametric models are widely used in biomechanics for identifying anatomical landmarks or rotations centers of these structures. For the scapula, no such model is available. We elaborated a first parametric model of scapula based on a large database of 43 scapulae. Our morphometric measurements are very close to others founded in literature. Correlations obtained should help to progress toward relevant subject-specific models of the scapula based on reduced information.

Abstract:The glenohumeral joint is a one of the joints most of which frequently dislocate. Moreover, in this joint various developmental disorders and pathological situations can be seen. The fact that it can perform the widest and the most diverse movements of our body makes the joint surfaces constituting the joint important. Therefore, in this study, surface areas of humeral head and glenoid cavity which form glenohumeral joint of 12 New Zealand rabbits of both sexes were measured, and their proportions to each other were determined on a three dimensional (3D) model obtained via photogrammetric methods. In conclusion, a statistically significant difference was identified between male and female rabbits regarding the joint surfaces constituting glenohumeral joint. Moreover, it was observed that the surface of humeral head was 3 times as large as the surface area of glenoid cavity. It has been suggested that the photogrammetric method that was used and the data that were obtained will shed light on forensic medicine applications and contribute to the information pool in the field of anatomy in veterinary medicine.

Midshaft clavicle fractures are a very common occurrence. The current treatment of choice involves internal fixation with superior or anterior clavicle plating, however their clinical success and particularly patient satisfaction are decreasing. The implementation of intramedullary devices is on the rise, but data describing the intramedullary canal parameters are lacking. The aim of this study is to quantify the geometry of the clavicle and its intramedullary canal, and to evaluate the effect of gender and anatomical side. This study used three-dimensional image-based models with novel and automated methods of standardization, normalization, and bone cross-section evaluation. The data obtained in this study present intramedullary canal, and clavicle diameter and center deviation parameterized as a function of clavicle length as well as its radius of curvature and true length. Results showed that both right-sided and female clavicles were shorter and thicker, but only females showed a statistically significant difference in size compared to males (p < 0.0001). The smallest clavicle and intramedullary canal diameters were seen at different clavicle lengths (45% and 52%), suggesting that the narrowest region of intramedullary canal cannot be appreciated based on external visualization of the clavicle alone. The narrowing of the intramedullary canal is of special interest because this is a potential limiting region for surgical planning and intramedullary device design. Furthermore, the location and value of maximum lateral curvature displacement is different in the intramedullary canal, implying there exists an eccentricity of the intramedullary canal center with respect to the clavicle center. © 2017 Orthopaedic Research Society.
