Aim: To determine the morphometric and biometric measurements of the normal Acromioclavicular (AC) joint on MDCT. Materials and methods: 33 volunteers (32 males and 1 female) and 17 patients (16 Male and 1 female) with clinical and radiographic evidences of AC separations were enrolled in this study. Two observers, blinded to the clinical data, assessed multiple AC joint morphologic and biometric variables. These were statistically attested for inter-observer variability and differences between the volunteers and diseased subjects. Results: The anterior and posterior axial AC joint distances were the only statistically significant variables measuring 0.59 ± 0.27 cm and 0.26 ± 0.11 cm in volunteers, and 0.88 ± 0.3 cm and 0.49 ± 0.39 cm in the AC separation group. The remaining attested variables were not statistically significant. Conclusion: On MDCT, the normal AC joint articular facet morphology shows great variability. The axial anterior and posterior AC joint distances measures 0.59 ± 0.27 and 0.26 ± 0.11 cm; respectively in supine neutral resting position.
