Introduction: An immense knowledge about the shape of the glenoid cavity is necessary for TSA. This study aims to evaluate the dimension of the glenoid cavity and to compare the morphological measures of scapula between genders. Materials and methods: A total of 32 males and 32 females were selected for the shoulder scan and the measurements were taken in 2D axial plane and 3D reconstructed images. Statistical analysis was done using SPSS Version 21.0. P < 0.05 was taken as significant. Result: Out of five diameters that we considered in this study, the superior-inferior (SI) mean glenoid diameter is 33.09 ± 3.82 mm. The anterior-posterior average glenoid diameters AP1, AP2, AP3 and AP4 are 15.08 ± 3.03 mm, 18.12 ± 3.26 mm, 21.03 ± 2.41 mm, 22.1 ± 2.54 mm, respectively, in total population. Six angles were considered, the Axis of glenoid, Axis of scapula, Axis of humeral head, axis of the glenoid neck, Resch angle and version of glenoid, measured 132.51° ± 5.46° , 43.03° ± 5.04° , 132.44° ± 5.04° , 58.48° ± 6.42° , 72.92° ± 4.79° , - 5.21° ± 1.45° , respectively, for the total population. The specific cut-off points for SI, AP1, AP2, AP3 and AP4 are 35, 15.35, 18.1, 21.55 and 22.65, respectively. Conclusion: The morphological measures such as Axis of glenoid, Axis of humeral head, Resch angle and Axis of scapula show that there exists a statistically significant difference between two genders. Hence, these four measures have a vital role in gender identification of an unknown scapula. All the diameters in this study have got specific cut-off points and it will be most useful to discriminate the gender from an unknown scapula.
