Patent number: 9402636Abstract: A cutting guide for performing a bone osteotomy procedure is disclosed. The cutting guide includes a first arm having a first cutting guide surface formed therein, a second arm having a second cutting guide surface formed therein pivotably connected to the first arm and a distractor operatively connected to the first arm. The cutting guide is adapted to be affixed to the bone such that the first cutting guide surface is open to the second cutting guide surface. The first arm and second arm are rotatable with respect to each other such that manipulation of the distractor creates a force between the first arm and the second arm causing rotation of the first arm and second arm relative to each other. A method for using the cutting guide in a bone osteotomy procedure is also disclosed.Type: GrantFiled: December 8, 2014Date of Patent: August 2, 2016Assignee: Howmedica Osteonics Corp.Inventor: Carlos E.

Patent number: 9339280Abstract: The present invention relates to systems and methods for preparing the trochlear groove of a patient's femur to receive a prosthesis thereon. In the system, a combination drill-and-alignment guide includes at least a proximal and intermediate section, and preferably also includes a distal section. Guide holes for receiving guide pins therein are located in the proximal and distal sections of the guide. After the guide is positioned using at least one of several visual and/or tactile guide references in the system, the guides pins are placed through the guide holes of the guide and into bone. The guide may then be removed and replaced by cannulated reamers that are rotated and used to resect a predetermined amount of bone around the guide pins. A prosthesis having at least a portion of an outer surface that substantially matches the trochlear groove of the patient in a pre-degenerated state is then implanted on the resected bone.Type: GrantFiled: July 2, 2013Date of Patent: May 17, 2016Assignee: Stryker CorporationInventors: Carlos E.
