Abstract: The apparatus comprises a base in slots of which two posts are removably mounted. One post is provided for supporting an orthopedic support in form of a shoe and the other post for supporting a set of two cradle splints. The cradle splints are pivotably coupled together by means of a hinge joint. A mechanism is provided for permitting adjustment of the mutual distance between the cradle splints as well as of their mutual angle of inclination. One cradle splint supports the calf and the other the thigh of a patient. The set of two cradle splints may be further adjusted at a given distance above the base and the angle of inclination of the cradle splint supporting the calf may be adjusted with respect to the plane of the base. The orthopedic support may be angularly adjusted in the plane of the sole and in a sagittal plane perpendicular thereof. Extension pieces may be provided in the case of extension of the leg. The apparatus has a great number of applications in the field of orthopedy.
