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.

成人肩胛骨关节臼腔的形态计量学分析及其临床意义

背景：肩胛骨的关节臼腔很小，只能容纳有限的固定装置。在全肩关节置换术中，正确固定肩关节盂组件是防止松动的关键，这是翻修手术的常见指征。整形外科医生和假肢设计师必须彻底了解关节盂的尺寸和形状，才能制造出最好的可行假肢。目的和目的：确定关节窝指数（GCI）和关节窝的形状，以及上下直径、最短前后直径和最长前后直径。材料和方法：对50例来自斯利那加GMC的北印度人群的干燥未配对成人肩胛骨进行研究。使用游标卡尺对所有重要的形态计量参数进行了研究。结果：上下径、最短前后径和最长前后径的平均值分别为35.06mm、15.8074mm和23.3814mm。42%的关节盂腔呈倒逗号形，36%呈梨形，22%呈椭圆形。结论：研究结果表明，关节盂上下平均直径约为35mm，而市场上用于肩关节置换术的假体平均从40mm起。这表明，在北印度人群中开发和安装用于全肩关节置换术的关节盂组件时，可能有必要考虑到关节盂腔的较小尺寸。

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.
