Morphometric Analysis of Clavicle: A Multi-Detector Computed Tomography Study

Abstract

The clavicle, a critical component of the shoulder girdle, plays a vital role in upper limb mobility and structural integrity. Its morphometry dimensions have significant clinical implications, particularly in orthopedic surgery, trauma management, and implant design. This study aims to analyse the morphometric characteristics of the clavicle using multi- detector computed tomography (CT) imaging. A total of 120 clavicles from a diverse adult population were evaluated using multi-detector CT scans. Measurements included clavicular length, width and depth of curvature at different segments. The study also assessed variations based on laterality (right vs. left) and gender differences. Preliminary findings indicate considerable individual and demographic variability in clavicular morphometry. Male clavicles exhibited greater dimensions than female counterparts, and significant asymmetry was observed between the right and left clavicles. Understanding these morphometric variations is crucial for optimizing surgical procedures such as intramedullary nailing and fracture fixation. This study provides a comprehensive database on clavicular morphometry, aiding orthopedic surgeons in preoperative planning and implant customization. The findings also contribute to forensic anthropology, prosthetic development, and biomechanical modelling. Future research may explore population-specific variations and the impact of age-related changes on clavicular structure.
