Abstract:
1. A ligament-tensioning device for activation of a ligament and/or capsule system in the implantation of a joint implant, said device comprising: a distal bearing plate adapted to bear against a distal skeletal part; first and second proximal bearing plates, each of which at least partially overlaps said distal bearing plate when in a first in-use position, and adapted to bear against a proximal skeletal part; a displacer for relative displacement of said proximal bearing plates away from the distal bearing plate so as to increase their spacing from the distal bearing plate; and releasable locking devices each structured to selectively lock the distal bearing plate to a corresponding one of the first and second proximal bearing plates; wherein each releasable locking device has a first position that is engaged with both the distal bearing plate and the corresponding one of the first and second proximal bearing plates to maintain an initial distance therebetween; wherein each releasable locking device has a second position that is disengaged from one of the distal bearing plate and the corresponding one of the first and second proximal bearing plates to permit relative displacement of the corresponding one of the first and second proximal bearing plates away from the distal bearing plate to an increased distance therebetween; and wherein components of said ligament-tensioning device including the distal bearing plate, the first and second proximal bearing plates, and the displacer are dimensioned such that they can be accommodated between portions of the distal and proximal skeletal parts adjacent to the joint such that a joint capsule can be closed again while the components of the ligament-tensioning device are positioned in the joint capsule.
