Patent number: 8821503Abstract: The ancillary tool according to the invention comprises a handle for manipulating an acetabulum provided, in its distal part, with a head for gripping the acetabulum and, in its proximal part, with a surface for application of a force of impaction. The tool further comprises at least one added endpiece adapted to be removably connected to the distal end of the handle. This endpiece defines both a face for wedging the acetabulum and an opposite face for interaction of the endpiece with the head of the handle, these faces both being borne by a radially deformable supple ring. The invention is particularly applicable to the positioning of an acetabular prosthesis in an anatomical or prosthetic cavity of a patient's hip.Type: GrantFiled: June 24, 2008Date of Patent: September 2, 2014Assignee: Tornier SASInventors: Alain Tornier, Jean-Pierre Berger, Patrick Reynaud, Arnaud Godeneche, Christophe Hulet, Jean-Claude Panisset, Philippe Deroche, Jean Puget, Andre Ferreira

Publication number: 20130060341Abstract: This glenoidal component for a shoulder prosthesis comprises a base which may be immobilized on the glenoid cavity of a shoulder, and an element provided to be mounted on this base and forming a convex surface of articulation centred on an axis of symmetry. This axis of symmetry is non perpendicular to a rear face of the base intended to abut against the glenoid cavity, this making it possible to compensate a defect in parallelism between the resectioned surface of the glenoid cavity and the axis of the patient's spinal column. A surgeon can select the component most adapted to the orientation of the resectioned surface from a set of components in which the axes of symmetry of the components are oriented differently with respect to their rear faces.Type: ApplicationFiled: October 30, 2012Publication date: March 7, 2013Applicant: TORNIER SASInventor: TORNIER SAS

Patent number: 8118875Abstract: An orthopedic device for ball and socket joint reconstruction. The anchor stem is adapted to be anchored in a medullary canal. A proximal portion of the anchor stem includes a threaded hole oriented along a longitudinal axis thereof. Metaphyseal portion includes a proximal end with recess and a longitudinal bore in fluid communication with the recess, and a distal end adapted to interface with the proximal portion of the anchor stem. An anti-rotation structure is preferably located at an interface of the anchoring stem to the metaphyseal portion to prevent rotation of the anchor stem relative to the metaphyseal portion around the longitudinal axis. A fastener is provided to extend through the longitudinal bore and to engage with the threaded hole on the anchor stem to fix the metaphyseal portion to the anchoring stem. The locking assembly is located in the recess and mechanically couples the head of the fastener to the metaphyseal portion to limit rotation of the fastener relative to the metaphyseal portion.Type: GrantFiled: September 18, 2008Date of Patent: February 21, 2012Assignee: Tornier SASInventor: Vincent Rollet

Patent number: 8080063Abstract: A glenoid component for a shoulder prosthesis adapted to be mounted in a glenoid cavity of a shoulder. An elongated keel adapted to engage with the glenoid cavity is attached to the internal surface of the base. The keel extends along a longitudinal axis of the base. The keel includes various configurations of transverse members extending away from the longitudinal axis. The surgeon selects a glenoid component with a keel and transverse member configuration that is anatomically optimized for the patient. Glenoid components properly optimized provide mechanical strength and stability superior to prior art devices. The glenoid components disclosed herein are particularly well suited for use in an anatomical total shoulder prosthesis, but may are also suited to partial shoulder prostheses and reverse shoulder prostheses.Type: GrantFiled: April 13, 2007Date of Patent: December 20, 2011Assignee: Tornier SASInventors: Lucile Ferrand, Irene Ferrari, Yves-Alain Ratron

Patent number: 7993346Abstract: A method for implanting a malleolar implant in an ankle joint. A spacer block is positioned between a lower portion of a tibia and an upper portion of an astragalus in the ankle joint. A guide attached to the spacer block is positioned opposite an outer surface of a fibular malleolus. A bore aligned with the guide is formed through the fibular malleolus. The spacer block is removed from between the tibia and the astragalus. A shank of the malleolar implant is engaged with the bore from an inner surface of the fibular malleolus. The shank is advanced into the bore so an inner surface of a head of the malleolar implant engages the inner surface of the fibular malleolus.Type: GrantFiled: October 27, 2008Date of Patent: August 9, 2011Assignee: Tornier SASInventors: Alain Tornier, Michel Bonnin, Jean-Alain Colombier, Thierry Judet
