Function of the elbow joint depends heavily on the trochlea of the humerus, and its radiomorphometric characteristics have important therapeutic ramifications. The purpose of this study was to examine the trochlea's radiomorphometry and its relationship to elbow disorders in five different age groups (18–65 years). The age groups of 26–35 and 56–65 had the highest representation (22.2%), while the age group of 18–25 had the lowest (16.7%). There was little variation among participants in the average values of the trochlear parameters, which showed consistent anatomical patterns: Capitulotrochlear Angle (CTA: 151.88°), Trochlear Sulcus Angle (TSA: 141.97°), and Trochlear Angle (TA: 102.83°). Gender distribution showed 44.4% females and 55.6% males, with balanced representation across all age groups except for those aged 56–65. Males had a significantly higher CTA (152.54°) than females (151.05°, p = 0.00**), but there were no discernible gender differences in TA or TSA. According to correlation analysis, elbow disorders were more strongly predicted by TSA (r = 0.35, p = 0.01) and CTA (r = -0.28, p = 0.02) than by TA (r = 0.21, p = 0.05). The incidence of disorders was positively correlated with TSA and negatively correlated with CTA. With particular attention to gender and age-based variations, these findings highlight the clinical utility of trochlear morphometry in the diagnosis and treatment of elbow pathologies.
