TIBIA TRIAL JIG FOR ARTIFICIAL KNEE ARTICULATION REPLACEMENT

摘要

PROBLEM TO BE SOLVED: To provide a trial jig by which adjustment of the tension level at an articulation and determination of the thickness of an insert can be securely performed in a short time in artificil knee articulation replacement. SOLUTION: This tibia trial jig 10 is set on an ablation part of the tibia to determine the thickness of an insert and is equipped with a base 11 set on the ablation part of the tibia, a movable part 17 vertically movably supported on the base 11 via vertical moving mechanism 19, and a pin 24 (gauge for measurement) to measure the distance from the upper end face of the base 11 to the upper end,face of the movable part 17 by a scale formed on the side face to determin the thickness of above insert insert.
