An articulated coupling or joint (10) for orthopedic braces or orthoses comprises a pair of bars or uprights (14, 15), a proximal end of each of these being rotatingly mounted around an axis defined by its rotation pin (25), this proximal end of the bars or uprights being toothed and engaging with a common grooved cylindrical cursor (20) translatable along an additional axis, the other distal end of the respective bars (14, 15) being fixable to a portion of the body of the patient to be treated. Each bar or upright (14, 15) is mounted on a respective element (12, 13) on which the respective rotation pin (25) is mounted and which itself is rotatingly mounted on an additional pin (18) coaxial with the additional axis; moreover, the additional pin (18) is mounted on a platform (11), a surface of which rests against the body of a patient to be treated, the two bars (14, 15) thus being able to simultaneously rotate both around their own primary centres of rotation represented by their rotation pins (25) and around a common centre of rotation represented by the additional pin (18).
