Abstract
The shoulder joint is the most commonly dislocated joint in the body. Several conditions can cause shoulder disability, like avascular necrosis, rotator cuff tear, or fractures. Therefore, patients are advised to consider shoulder joint replacement surgery as a long-term remedy. Glenoid component loosening is a long-term complication seen in arthroplasty. Biomechanics of the reconstructed glenohumeral joint need a better understanding, so that the reason behind glenoid component loosening can be identified. The goal of this study is to record and analyze the various parameters using a mould. In this study, 106 scapulae with intact glenoid were included in the study. Acrylic moulds were measured with a vernier caliper. The values were found to be symmetrical with respect to the right and left sides. New parameters which were studied include the thickness of the mould. The mean values at T1, T2, T3 were 2.95±0.75 mm, 2.67±0.74 mm, 2.26±0.55 mm respectively. The statistical significance was observed with the parameters. P-value was 0.002, 0.001 and 0.001 between Surface area - AP1, SI - AP and AP1 - T1 respectively. The dimensions which were from a mould give an added information about the depth of glenoid component, used for total shoulder arthroplasty.
