Abstract
A hip orthosis, provided with a trunk engaging part and an upper leg engaging part which are intercoupled by coupling means, wherein the coupling comprise at least one resilient element for operatively preventing an adducting movement of an upper leg engaged by the upper leg engaging part by means of spring force.
Claims27
A hip orthosis, comprising:
- a trunk engaging part;
- an upper leg engaging part;
- a coupling device intercoupling the trunk engaging part to the tipper leg engaging part, the coupling device having at least one resilient element for operatively preventing an adducting movement of an tipper leg engaged by the upper leg engaging part by a spring force,
- the coupling device comprising a connecting part connected to the upper leg engaging part and a coupling part connected to the trunk engaging part, wherein, during use, the connecting part is rotatable about a point of rotation with respect to the coupling part, wherein the point of rotation is defined as a virtual point of rotation;
- wherein the resilient element is defined as a leaf spring;
- wherein the at least one resilient element exerts a pressing force on a hip joint, such that a hip is pressed into a socket thereof under the influence of the pressing force.

A method for preventing the dislocation of a hip of a person, comprising the steps of
- attaching a trunk engaging part to the trunk of a wearer;
- attaching an tipper leg engaging part to the upper leg of a wearer;
- intercoupling the trunk engaging part with the upper leg engaging part by connecting a connecting part with the upper leg engaging part and connecting a coupling part with the trunk engaging part;
- operatively preventing an adducting movement of an upper leg engaged by the upper leg engaging part with a spring force provided by at least one resilient element having a leaf spring;
- responsive to movement of the person, rotating the connecting part about a point of rotation with respect to the coupling part, wherein said point of rotation is a virtual point of rotation;
- and
- preventing an inward movement of the associated tipper leg by a spring force;
- wherein the force is directed substantially such that the hip is pressed into its socket under the influence of that force.
