The invention concerns an anatomically personalized and mobilizing external support configured to be arranged to support a physical joint between a first and a second bone group, which support comprises at least one first external auxiliary frame, which is configured to be attached to the first bone group using invasive attachment means, at least one second external auxiliary frame, which is configured to be attached to the second bone group using invasive attachment means, and at least one external auxiliary joint, which is fitted between the first and the second auxiliary frame. The external support is configured to permit a rotation of the second external auxiliary frame relative to the first external auxiliary frame about a rotational axis, sliding of the rotational axis relative to the first external auxiliary frame in a first direction, and sliding of the rotational axis or at least a portion of the second external auxiliary frame relative to the first external auxiliary frame in a second direction, which differs from the first direction.

Anatomically personalized and mobilizing external support and method for controlling a path of an external auxiliary frame

The present invention relates to an anatomically personalized and mobilizing external support, a method for manufacturing is, as well as the use of a component of an invasively attached external support in determining the path of the joint being supported. In the method according to the invention, the kinetic dynamics of the joint are measured with the aid of a component of an external support invasively attached to two bone groups, on the basis of which an external support is arranged between the bone groups.
