Anatomically customized and mobilizing external support, method for manufacture

Abstract

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.

1 . An anatomically personalized and mobilizing external support between a first and a second bone group, which support comprises:
 at least one first external modular auxiliary frame, which is configured to be attached to the first bone group using invasive attachment means,   at least one second external modular auxiliary frame, which is configured to be attached to the second bone group,   at least one external modular auxiliary joint, which is fitted between the first and the second auxiliary frame, which at least one external modular auxiliary joint is configured to permit:
 rotation about a rotational centre point on a path having a radius as well as 
 sliding of the rotational centre point and 
 the alteration of the radius of the path, 
   at least one personalized adapter component, which is arranged to connect the auxiliary joint to the auxiliary frame and which at least one external modular auxiliary joint is made by additive manufacturing or machining.   
     
     
         2 . The anatomically personalized and mobilizing external support according to  claim 1 , wherein in the auxiliary frames there are measurement points, which are arranged to receive the measuring head of a coordinate measuring device. 
     
     
         3 . The anatomically personalized and mobilizing external support according to  claim 1 , wherein the at least one external modular auxiliary joint is adjustable in such a way that the angle between the at least one external modular auxiliary joint and the movement of a patient's joint between the first and second bone group can be adjusted. 
     
     
         4 . The anatomically personalized and mobilizing external support according to  claim 1 , wherein the external support comprises bone screws or cables or both as invasive attachment means for fixing the at least one first external modular auxiliary frame and the at least one second external modular auxiliary frame to the first and second bone group, respectively.
