ObjectiveEvaluate technical feasibility and potential applications of glenohumeral (GH) joint axial traction magnetic resonance imaging (MRI) in healthy volunteers.Materials and MethodsEleven shoulders were imaged in neutral and with 4 kg axial traction at 3 Tesla. Quantitative measurements were assessed.ResultsAxial traction was well tolerated. There was statistically significant widening of the superior GH joint space (p=0.002) and acromial angle (p=0.017) with traction. Inter-rater agreement was high.ConclusionGH joint axial traction MRI is technically feasible and well tolerated in volunteers. Traction of the capsule, widening of the superior GH joint space and acromial angle were observed.
