ABSTRACT:
A hip joint for orthopedic orthesis comprising a pelvic attachment to which the tops of two arms are articulated, and in which the arms are adapted to be rigidly coupled to the top of respective thigh-leg-foot braces and are provided with respective hip locking devices that can be disengaged manually to allow the patient to sit; two bushes having substantially vertical axes are fixed laterally to the pelvic attachment and two shafts are articulated to the bushes; the arms are articulated to the shafts in a downward region about substantially horizontal axes; the arms are provided with elements for kinematic connection to the bushes, so that each torsion of the shaft with respect to the bush is matched by a rotation of the arm with respect to the shaft; and the arms are connected by motion transmission elements adapted to complementarily transmit the rotation-torsion movements from one arm to the other.
