  • Publication number: 20170164992
    Abstract: The instrumentation makes it possible to implant in a long bone, such as the humerus, the femur or the tibia, an implant, such as an osteosynthesis nail or a prosthetic rod, defining a longitudinal axis and including, in alignment along the longitudinal axis, two opposite terminal parts and a running part that separates the two terminal parts from one another. The instrumentation comprises a targeting ancillary tool that is adapted to target one and/or the other of the terminal parts of the implant, if applicable percutaneously, along at least one targeting axis that is transverse, or even perpendicular, to the longitudinal axis. The targeting ancillary tool is designed to be fastened laterally to the running part of the implant so as to position the targeting ancillary tool and the implant relative to one another in a predetermined configuration.

  • Publication number: 20160331555
    Abstract: Methods of implanting a prosthesis to repair a joint include displacing a first bone from the joint formed by an intersection between the first bone and a second bone. An end portion of the first bone is resected to define a resected end. A concavity is formed into the resected end using a shaping tool. The bone is compacted to form a support layer lining the concavity. The prosthesis is implanted in the concavity against the support layer without attaching the prosthesis to the support layer. The joint is reformed with the prosthesis such that the prosthesis remains unattached to the support layer and the first and second bones articulate about the prosthesis.

  • Publication number: 20160242933
    Abstract: A patient specific glenoid guide is provided to facilitate properly aligned implantation of a glenoid prosthesis into a patient. The guide shape is designed preoperatively based on the unique configuration of the scapula of the patient. The guide orientation is chosen preoperatively based on one or more of the bone structure of the patient, the wear pattern of the patient's glenoid cavity, the anchoring means of the glenoid prosthesis, or other aspects.

  • Publication number: 20150374502
    Abstract: A glenoid component for coupling to a scapula of a subject includes a body. The body includes an articulation surface adapted to articulate with a humeral component, and the body further includes a distal surface adapted to face the glenoid of the scapula. The distal surface includes a base surface portion adapted to face a first portion of the glenoid. The distal surface further includes an augmented surface portion adapted to face a second portion of the glenoid. The base surface portion and the augmented surface portion define an obtuse angle therebetween.

  • Publication number: 20150265411
    Abstract: Embodiments of the present invention include a convertible prosthesis that is capable of conversion from a humeral head replacement to a reverse reconstruction without any removal of parts integrated into the patient's bony anatomy (e.g. implant stems). A desired overall implant inclination angle may be achieved by matching various implant stems with various reverse inserts, thus permitting a resection surface to be matched with an implant stem selection while also permitting a desired overall implant inclination angle to be achieved through the selection of an appropriate insert.
