  • Device and method for determining at least one characteristic point of joint to be orthopedically measured
    Patent number: 7837635
    Abstract: A device determines at least one characteristic point of a joint which joins together two limbs and is to be measured orthopedically comprising a first coupling element which may be positioned on a first limb adjoining the joint, a second coupling element which may be moved relative to the first coupling element and may be positioned on a second limb adjoining the joint, and a measuring device for determining the position of the first coupling element relative to the second coupling element. The measuring device has at least one reference point rigidly connected to one of the first and second coupling elements, and a reference point detection device rigidly connected to the respective other of the first and second coupling elements. During a movement of the first and second limbs with respect to one another the reference point detection device determines the at least one characteristic point.
