Thiesen DM, et al. - Researchers assessed the role of glenoid version, inclination, and rotator interval dimension in patients aged > 40 years with an anterior shoulder dislocation to determine the role of the rotator interval in the osseus alignment of older patients. Glenoid version, inclination, height and width, rotator interval height, base (width) and area were measured by two shoulder surgeons. Findings revealed that the shape of the glenoid rather than its spatial position bears significance in this study population. A wide and high rotator interval advances anterior shoulder dislocation in these patients.
