Publication number: 20230270557Abstract: A method for securing a stemless humeral includes positioning the stemless humeral anchoring component to the humerus such that a lateral anchoring wing extends in a direction of a lateral side of the humerus into a lateral region and two medial anchoring wings face a medial side of the humerus in a medial region. The lateral region has a lower bone density relative to the medial region. The stemless humeral anchoring component is positioned eccentrically such that the anchoring stud and the two medial anchoring wings are anchored in the medial region. The stemless humeral anchoring component is secured in resected proximal epiphyseal and metaphyseal portions of the humerus without reaching a diaphyseal portion of the humerus.Type: ApplicationFiled: May 8, 2023Publication date: August 31, 2023Applicant: SHOULDER FRIENDS INSTITUTEInventors: Yves LEFEBVRE, Stephane AUDEBERT, Johannes BARTH, Christophe CHAROUSSET, Jerome GARRET, David GALLINET, Arnaud GODENECHE, Jacques GUERY, Thierry JOUDET

Patent number: 11471293Abstract: A glenoidal implant for a shoulder prosthesis includes an articular body having two opposite faces which are an articulation face suitable for cooperating with an articulation head of a humeral implant, and an anchoring face from which at least one anchoring stud protrudes for an anchoring in the glenoid cavity including a main anchoring stud at least partially covered with a porous or rough surface coating promoting an osseointegration. The main anchoring stud is provided internally with a central hole extending along a central axis of symmetry of the main anchoring stud and provided to allow guiding a trephine.Type: GrantFiled: May 28, 2020Date of Patent: October 18, 2022Assignee: SHOULDER FRIENDS INSTITUTEInventors: Stephane Audebert, Johannes Barth, Christophe Charousset, Jerome Garret, David Gallinet, Arnaud Godeneche, Jacques Guery, Thierry Joudet, Yves Lefebvre

Patent number: 11439513Abstract: A glenoid implant for an inverted shoulder prosthesis includes a base, a glenosphere having a central orifice and mounted on the base by mutual wedging between conical bearing surfaces, a main anchoring screw crossing the base and including an anchor rod having a tapped end segment, and an inner hole having a threaded intermediate portion, and a tip portion. A locking screw crosses the central orifice and includes a proximal head and a locking rod having an end segment intended to slide in the tip portion of the inner hole and a tapped intermediate segment intended to cooperate by screwing with the intermediate portion of the inner hole to lock the mutual wedging of the conical bearing surfaces, the proximal head abutting on an annular bearing surface in the central orifice.Type: GrantFiled: May 28, 2020Date of Patent: September 13, 2022Assignee: SHOULDER FRIENDS INSTITUTEInventors: Yves Lefebvre, Stephane Audebert, Johannes Barth, Christophe Charousset, Jerome Garret, Arnaud Godeneche, Jacques Guery, Thierry Joudet, David Gallinet

Patent number: 11426283Abstract: A modular humeral implant for an inverted shoulder prosthesis includes a humeral stem having, on the one hand, a diaphyseal keel of elongate shape, extending along a diaphyseal axis and shaped to be engaged in a medullary cavity of a humerus, and, on the other hand, a metaphyseal portion. A humeral spacer is mounted on the metaphyseal portion of the humeral stem and has a lower face facing the metaphyseal portion, the lower face having a peripheral portion projecting laterally from the metaphyseal portion and covered at least partially with a porous or rough metal surface coating promoting an osseointegration. A humeral insert is fastened on the humeral spacer and has a hemispherical cup shaped to receive a glenosphere of a glenoid implant.Type: GrantFiled: May 28, 2020Date of Patent: August 30, 2022Assignee: SHOULDER FRIENDS INSTITUTEInventors: Yves Lefebvre, Stephane Audebert, Johannes Barth, Christophe Charousset, Jerome Garret, David Gallinet, Arnaud Godeneche, Jacques Guery, Thierry Joudet

Patent number: 11253276Abstract: A guide for positioning an orthopaedic guide pin on a bone structure includes a base having an upper face, a lower face intended to bear against the bone structure, and a through-hole for the pin, said guide including several bearing members able to move in guide holes formed in the base, wherein each bearing member has a lower end facing the lower face and is able to be moved selectively between a retracted position inside the guide hole and at least one deployed position in which the bearing member protrudes from the lower face so as to have a salient lower end intended to bear against the bone structure in order to allow the base to be inclined.Type: GrantFiled: March 22, 2021Date of Patent: February 22, 2022Assignee: SHOULDER FRIENDS INSTITUTEInventors: Yves Lefebvre, Stephane Audebert, Johannes Barth, Christophe Charousset, Jerome Garret, David Gallinet, Arnaud Godeneche, Jacques Guery, Thierry Joudet

Patent number: 11246711Abstract: An integral humeral stem includes a diaphyseal portion which has, orthogonal to a diaphyseal axis, an octagonal cross-section with convex rounded angles, and a metaphyseal portion in the form of a flared corolla which extends the diaphyseal portion up to a proximal face, which has, orthogonal to a central axis, an octagonal cross-section with convex rounded angles so that the humeral stem has a peripheral surface provided with eight lateral facets and eight rounded fillets which continuously extend from the diaphyseal portion to the metaphyseal portion. On the metaphyseal portion, the rounded fillets progressively widen and the lateral facets progressively narrow from the diaphyseal portion in the direction of the proximal face.Type: GrantFiled: May 28, 2020Date of Patent: February 15, 2022Assignee: SHOULDER FRIENDS INSTITUTEInventors: Yves Lefebvre, Stephane Audebert, Johannes Barth, Christophe Charousset, Jerome Garret, David Gallinet, Jacques Guery, Thierry Joudet, Arnaud Godeneche

Publication number: 20200289277Abstract: A stemless humeral anchoring component for a shoulder prosthesis humeral implant includes an anchoring stud secured to anchoring wings extending radially along the periphery of the anchoring stud. The anchoring wings include a lateral anchoring wing and two medial anchoring wings angularly spaced by an angle between 110 and 130 degrees. The lateral anchoring wing has a radially measured length greater than the radially measured lengths of the medial anchoring wings.Type: ApplicationFiled: May 28, 2020Publication date: September 17, 2020Applicant: SHOULDER FRIENDS INSTITUTEInventors: Yves LEFEBVRE, Stephane AUDEBERT, Johannes BARTH, Christophe CHAROUSSET, Jerome GARRET, David GALLINET, Arnaud GODENECHE, Jacques GUERY, Thierry JOUDET
