Abstract
Background: The glenoid cavity of scapula is quite small, which allows space for only limited fixation devices. Appropriate fixation of the glenoid component of shoulder is of key importance in total shoulder arthroplasty to prevent loosening, which is a common indication of revision surgery. Orthopedic surgeons and prosthetic designers must have a thorough understanding of the glenoid’s dimensions and shape, in order to create the finest feasible prosthesis. Aims and objectives: To determine the glenoid cavity index (GCI) and the form of the glenoid cavity, as well as the supero-inferior diameter, shortest antero-posterior diameter, and longest antero-posterior diameter. Materials and methods: The study was conducted on 50 dry unpaired adult human scapulae of North Indian population obtained from GMC, Srinagar. All the important morphometric parameters were studied using a vernier calliper. Result: Supero-inferior diameter, shortest antero-posterior diameter, and longest antero-posterior diameter were found to have respective mean values of 35.06 mm, 15.8074 mm, and 23.3814 mm. Glenoid cavity index had a mean value of 66.68. 42% of the glenoid cavities had an inverted comma shape, 36% had a pear shape, and 22% had an oval shape. Conclusion: The results showed that mean supero-inferior diameter of glenoid is about 35mm while the average prosthesis for shoulder arthroplasty in the market starts from 40mm. This suggests that while developing and fitting glenoid components for total shoulder arthroplasty in the North Indian population, it may be necessary to take into account the smaller dimensions of the glenoid cavities.
期刊介绍：
The Italian Journal of Anatomy and Embryology, founded in 1901 by Giulio Chiarugi, Anatomist at Florence University, is a peer-reviewed journal sponsored by the Italian Society of Anatomy and Embryology. The journal publishes original papers, invited review articles, historical article, commentaries, obituitary, and book reviews. Its main focus is to understand anatomy through an analysis of structure, function, development and evolution. Priority will be given to studies of that clearly articulate their relevance to the anatomical community. Focal areas include: experimental studies, contributions based on molecular and cell biology and on the application of modern imaging techniques; comparative functional morphology; developmental biology; functional human anatomy; methodological innovations in anatomical research; significant advances in anatomical education. Studies that are essentially descriptive anatomy are appropriate only if they communicate clearly a broader functional or evolutionary significance. All papers should be submitted in English and must be original works that are unpublished and not under consideration by another journal. An international Editorial Board and reviewers from the anatomical disciplines guarantee a rapid review of your paper within two to three weeks after submission.
