Abstract
The present invention provides a method and device for restoring individual patient joint kinematics using minimally invasive surgical procedures. The instrumentation of the invention sculpts the articular surface of a first bone that normally articulates in a predetermined manner with a second bone. The instrumentation includes a bone sculpting tool and a mount for attaching the tool to the second bone. The implant system is comprised of implants that provide intraoperative surgical options for articular constraint and facilitate proper alignment and orientation of the joint to restore kinematics as defined by the individual patient anatomy.
Claims36
An apparatus for sculpting the articular surface of a first bone that normally articulates in a predetermined manner with a second bone, the apparatus comprising:
- a bone-sculpting tool;
- a mount attachable to the second bone for mounting the tool in position to sculpt the articular surface as the second bone is articulated in the predetermined manner with respect to the first bone.
An apparatus for sculpting the articular surface of a first bone that normally articulates in a predetermined manner with a second bone, the apparatus comprising:
- a plurality of bone-sculpting tools;
- and
- one or more mounts attachable to the second bone for mounting the tools in position to sculpt the articular surface as the second bone is articulated in the predetermined manner with respect to the first bone.
Method of sculpting the articular surface of a first bone that normally articulates with a second bone, comprising:
- a) providing a bone-sculpting tool and a mount,
- b) attaching the mount to the second bone with the tool in bone-sculpting engagement with the articular surface of the first bone, and
- c) sculpting the articular surface of the first bone by articulating one of the bones with respect to the other.
Method of sculpting the articular surface of a first bone that normally articulates in a predetermined manner with a second bone, comprising:
- a) providing a bone-sculpting tool and a mount, and an adjustable attachment for attaching the bone sculpting tool to the mount;
- b) attaching the mount to said second bone;
- and
- d) sculpting the articular surface of the first bone by articulating one of the bones with respect to the other.
A method of sculpting the articular surface of a first bone that articulates with a second bone, comprising attaching a bone-sculpting tool to the second bone with the tool in sculpting proximity to the articular surface of the first bone, and sculpting said articular surface by articulating the bones.
