Joint socket and joint endoprosthesis
The invention relates to a joint socket for a joint endoprosthesis, in particular in the form of a hip joint socket for a hip joint endoprosthesis. The joint socket has the form or substantially the form of a section of a hollow-spherical shell. The joint socket comprises a socket wall, in which socket wall at least one through-opening is formed. The through-opening is closed with a closure element. The closure element is formed as one piece with the socket wall. At least one predetermined breaking point is formed between the closure element and the socket wall. The at least one predetermined breaking point is irreversibly destroyable for removing the closure element from the socket wall. The joint socket comprises at least one connecting device for force- and/or form-fittingly connecting the closure element removed from the socket wall to the socket wall in a connecting position.
Glenoid implant and method of use thereof
A glenoid implant that is 3D-printed or machined from ceramic and/or metal as a substitute for an autograft or allograft in a surgical repair. Structural supports composed of metal are designed in the interior of the implant for support during implantation and post-operation. The remainder of the volume of the implant is composed of a material having optimal pore structure for rapid bone integration and healing.
Fusion cage with integrated fixation and insertion features
A surgical implant system includes an implant and a fixation member for securing the implant to tissue. The implant and the fixation member together comprise a single monolithic structure. The implant includes an insertion instrument. The implant, the fixation member, and the insertion instrument together comprise a single monolithic structure and are constructed from a single material. The implant is monolithically connected to the fixation member at a first frangible connection and is monolithically connected to the insertion instrument at a second frangible connection. Each of the frangible connections can be broken when force is applied.
Intervertebral Spacer for TLIF Implant Procedure
An intervertebral spacer is disclosed having a main body and an articulating component that is pivotally mounted within an opening of the main body. The intervertebral spacer is designed to be manufactured using an additive manufacturing process without the use of any frangible support material between a main body of the intervertebral spacer and an articulating component of the intervertebral spacer. To this end, an article of manufacture is provided in which supports are formed prior to forming intervertebral spacer. The supports are configured to support the main body and the articulating component such that they can be separately, but simultaneously manufactured using an additive manufacturing process atop the supports, without the need for any frangible support material therebetween.
Counter-Torque Revisable Stemless Shoulder Implant
A base member of a prosthetic stemless shoulder implant may include a proximal collar, a central anchor, and at least one peripheral anchor. The proximal collar may have a proximal surface and a distal bone-engaging surface opposite the proximal surface. The central anchor may extend distally from the bone-engaging surface and define an opening extending from the bone-engaging surface into the central anchor for receiving a humeral head component of the prosthetic stemless shoulder implant. The at least one peripheral anchor may be positioned radially outwardly of the central anchor and extend distally from the bone-engaging surface. The peripheral anchor may be frangibly connected to the proximal collar.
METHOD AND APPARATUS FOR MINIMALLY INVASIVE INSERTION OF INTERVERTEBRAL IMPLANTS
A dilation introducer for orthopedic surgery is provided for minimally invasive access for insertion of an intervertebral implant. The dilation introducer may be used to provide an access position through Kambin's triangle from a posterolateral approach. A first dilator tube with a first longitudinal axis is provided. A second dilator tube may be introduced over the first, advanced along a second longitudinal axis parallel to but offset from the first. A third dilator tube may be introduced over the second, advanced along a third longitudinal axis parallel to but offset from both the first and the second. An access cannula may be introduced over the third dilator tube. With the first, second, and third dilator tubes removed, surgical instruments may pass through the access cannula to operate on an intervertebral disc and/or insert an intervertebral implant.
Bone implant augment method and apparatus
The strength of bone implant attached to a bone is improved by using hybrid inserts which have stems and wings having bone ingrowth surface features and caps having outer surfaces of cured polymethyl methacrylate (PMMA). The stems and wings of the hybrid inserts are inserted into living bone and the bone implant is attached to the hybrid inserts with PMMA cement. Over time, the bone grows into the bone ingrowth surface features. The bone ingrowth strengthens the bonding of the hybrid inserts and the bone implant with the bone over time. The hybrid inserts increase the shear, tensile and torque strength of the bone implants. Bone inserts that do not have ingrowth surface features loosen over time.
AUGMENT INSERT, SHOULDER PROSTHESIS AND KIT COMPRISING THE AUGMENT INSERT
This augment insert (200), comprises a coupling member (204) for securing the augment insert to a glenoid component (103) of a shoulder prosthesis (101), and a body (202), comprising a first side (206), configured to bear against a scapular side (107) of the glenoid component when the augment insert is secured to the glenoid component by means of the coupling member; and a second side, opposed to the first side and configured to bear against or be adjacent to a scapula of a patient. According to the invention, the body (202) comprises at least one breakable portion (230), extending from the first side (206) to the second side and configured to be broken off the body. The aperture (234) is provided for accommodating an engaging member (111) of the glenoid component (103), said engaging member protruding from a scapular surface (127) of the scapular side (107) of the glenoid component (103) and being configured for securing the shoulder prosthesis to the scapula.

An access cannula may be introduced over the third dilator tube. With the first, second, and third dilator tubes removed, surgical instruments may pass through the access cannula to operate on an intervertebral disc and/or insert an intervertebral implant.
