Abstract:
1. A ligament-tensioning device for activating the ligament and/or capsule apparatus during implantation of a joint implant, having a base member comprising a first claw with a distal bearing surface, which is adapted to bear on a first bone, and a second claw, which is adapted to bear with a proximal bearing surface on a second bone, wherein the second claw is of a two-part construction having a distal part and a proximal part, wherein the distal part is displaceable relative to the proximal part to enable displacement of the second claw in an anteroposterior direction and/or mediolateral direction parallel to the first claw, wherein displacement of the second claw in a craniocaudal direction is enabled by a parallel displacement device, a projection comprising catches that are formed on the proximal part of the second claw being guided in a guide, a locking device being movably engageable in the catches, and the locking device possessing the form of a tilting or rocking arm which is pivotable about an axis.
