Morphometric Study of Glenoid Cavity in South Indian Population
Journal Title: Indian Journal of Anatomy - Year 2017, Vol 6, Issue 3
Abstract
Background: The glenoid cavity is a shallow pyriform articular surface on the lateral angle of scapula. The shape and dimensions of glenoid cavity are important in the design and fitting of glenoid component for total shoulder arthroplasty. The shoulder arthroplasty is a common orthopedic intervention in the clinical management of shoulder arthritis. Appropriate fixation of glenoid component is essential to evade loosening which is the common indication for revision surgery. Aims and Objectives: To determine the morphometry of glenoid cavityof scapula bones belonging to South Indian population. To assess the incidence of different shapes of glenoid cavity. Methodology: The present study was carried out on 182 dry adult scapulae of unknown sex belonging to South Indian population. Three glenoid diameters were measured using Vernier caliper. The shape of glenoid cavity was classified as inverted comma, pear and oval shape based on a notch present on anterior glenoid rim. Results: The mean superior-inferior diameter was 34.70 ± 3.64 mm. The mean anterior-posterior diameter of lower half of glenoid cavity was 23.59 ± 2.33 mm. The average anterior-posterior of upper half was 15.50 ± 1.55 mm. Conclusion: The left glenoid cavity was slightly longer in length. This fact may be taken into consideration while designing glenoid prosthesis for south Indian population. The morphometric data regarding the glenoid cavity will be helpful in evaluating the defects or lesions of glenoid cavity and is important in the diagnosis and management of diseases of shoulder joint.
