An orthosis that provides hinging action between two shell parts that are on opposite sides of a skeletal joint of a limb is provided with joint components on the medial and lateral sides of the skeletal joint. A spherical bearing connection between two parts of each of the joint components is used. The spherical connection is such that the pivot axes of the medial and lateral joint component do not have to be precisely coaxial when hinging due to the accommodation by the spherical bearing. Also, in fabricating an orthosis, a dummy joint component is used in the molding process, or, for metal frame fabrication and repair, the joint is plugged in neutral alignment during the fabrication process.
