Publication number: 20190209343Abstract: The invention relates to a method for the removal of a bone insert, for example a bone insert for a shoulder prosthesis, comprising: forming a hole of predefined diameter inside a proximal bone portion from which said bone insert is to be removed; inserting inside said hole an operating end of an instrument provided with a cutting element, wherein said cutting element is moveable to project through a side opening in said operating end, transversely with respect to a longitudinal axis of the instrument; deep-cutting by the cutting element a distal base of said bone insert, wherein said instrument is pushed and is rotated through 360 degrees around its longitudinal axis; removing the instrument from said hole; inserting and fixing a pin element inside said hole; perimetrally milling the bone insert at a predefined second diameter, by centering a milling cutter on said pin element; removing the bone insert and the pin element attached thereto.Type: ApplicationFiled: March 12, 2019Publication date: July 11, 2019Inventors: MICHELE PRESSACCO, SIMONE URSELLA, CHRISTOPH FIEDLER, PAUL D. PATERSON

Patent number: 10258484Abstract: The invention relates to an instrument and a corresponding surgical method for the removal of a bone insert, for example for a shoulder prosthesis. The instrument is of the type comprising: a stem-like body (40) extending along a longitudinal axis (x-x) and provided with a proximal grip and a distal operating head (15) slidably associated with the stem-like body (40) for movement towards and away from each other; a cutting element (30) inside said operating head; and an end tip (16) protruding coaxially from said operating head. The following is also provided: a pushing mechanism (8), inserted inside said operating head and acting on said cutting element so as to displace it angularly from a rest position, where it is concealingly housed inside said end tip, to an operative position where it projects through a side opening in the end tip; said cutting element having an end extending substantially in a direction transverse to said longitudinal axis when in the operative position.Type: GrantFiled: June 12, 2014Date of Patent: April 16, 2019Assignee: LimaCorporate S.P.A.Inventors: Michele Pressacco, Simone Ursella, Christoph Fiedler, Paul D.

Patent number: 9867710Abstract: A modular humeral prosthesis suitable for implant in a humeral seating of a humerus comprises an articulation component, a distal joint element able to be inserted into said humeral seating along an insertion axis, and an adapter body provided with a support positionable in the humeral seating and that has a coupling seating to connect said articulation component and provided with a connection unit inserted into said support to connect said distal joint element to said adapter body in a releasable manner. The connection unit comprises a clamping element associated in a selectively releasable manner to the distal joint element and the support has a through coupling seating configured to receive and position said clamping element inside it, and also configured to allow the insertion and extraction of said distal joint element through said support without removing said support from the humeral seating.Type: GrantFiled: June 6, 2014Date of Patent: January 16, 2018Assignee: LIMACORPORATE S.P.A.Inventors: Paolo Dalla Pria, Michele Pressacco, Simone Ursella
