Title:
【発明の名称】自然の膝と自然の臀部の領域との間のトルクを再構成するためのシステム
Document Type and Number:
Japanese Patent JP2001524344
Kind Code:
A
Abstract:
The system includes a nail jig which is initially secured by means of fixing nails (38), after production of a stable three-point mounting of plates and legs extending from the nail jig, on the femur (10) in the vicinity of the condyles of the knee joint. The nail jig can then be removed from the femur (10), leaving the fixing nails (38) in the femoral bone. A saw jig (40) with the same basic shape as the nail jig and with identical holes for the fixing nails (28) can be placed on the fixing nails which were left in the femur (10). Precise allocation of boring pairs by both the nail and saw jig enables twist to be transferred to the artificial knee joint system at a ratio of 1:1 according to the predetermined size of the part of the femur to be implanted. In order to compensate for the incline in the frontal resection surface which is attached at a slant, the system is provided with a compensating wedge (46) which is inserted between the striking plate (32) and the lateral condyle (39'). The compensating wedge angle is similar to the angle of the horizontal resection surface in relation to the axis of the gap in the knee.
