Morphometric Study of the Clavicle in Normal Adult Shoulders in East Java, Indonesia: A 3D Computed Tomography Analysis

Introduction: Clavicle plate should be well measured in its production process, since size mismatch often leads to complications like implant prominence, screw loosening, and malunion. The study aims to investigate the clavicle morphometry of adults in Indonesia to aid in preventing complications caused by mismatch of clavicle plates for the better treatment of clavicle fractures. Materials and methods: This retrospective study investigates clavicle morphometry in normal adult subjects from East Java through a comprehensive analysis of 3D computed tomography (CT) scans collected between July 2022 and June 2023. The Radiant Dicom application facilitated precise morphometric measurements. Sample size determination followed Slovin's formula to ensure representativeness of the East Java population. Age and gender data were recorded for each subject. Statistical analysis, conducted using SPSS version 25, involved ANOVA or independent t-test comparisons of morphometric parameters across gender and age groups. Results: In this study, a total of 385 patients were selected through simple random sampling, meeting the specified inclusion and exclusion criteria. Further analysis indicated that female clavicles were significantly shorter than male clavicles. Age and gender was significantly correlated with the superior view morphology of the clavicle (p = 0.005), but not in frontal view. Conclusion: This finding indicates that age and gender significantly correlate with the morphometric parameters of the clavicle. Therefore, the use of clavicle plates must take into account the patient's age and gender. The morphometric results of patients in East Java among adult was shorter which is differs from several other countries.
