摘要 |
The present invention relates to a method for determining the position of a point F1 of a femur (2) with respect to a point T1 of a tibia (1), such that the distance between F1 and T1 is substantially constant. This method resorts to a system for three-dimensional location of triplets of transmitter elements comprising, in particular, a pointer which can be located by this system and comprises the steps consisting in linking a first triplet (14) with the tibia; pointing with the pointer (20) to the position of the point T1 and locating this position with respect to that of the first triplet; pointing with the pointer to the positions of a set of second points (Fi) located in a region (A) of the femur where the invariant point may lie; calculating the distances (Di) between the point T1 and each of the points Fi; moving the tibia with respect to the femur and calculating the variations in the said distances; and selecting the point F1 for which the said distance is invariant. <IMAGE> |
