Implants, device, systems and methods for replacing an articulation surface in a joint, for example, a reverse glenoid implant with a baseplate, a central screw, a peripheral screw, a modular taper, and a post. Methods for implanting the glenoid implant are also disclosed.

An acetabular joint prosthesis may be designed to replace an acetabular articular surface. The prosthesis can include an acetabular cup, an augment, and an augment-securing mechanism configured to secure the augment to the cup. The mechanism can be reconfigured between an unlocked configuration in which a slider is slidable along a guide feature and a locked configuration in which the slider or guide feature is in an expanded form such that the slider is fixed in place relative to the guide feature. An unlocked configuration may include the augment-securing mechanism allowing rotation between the augment and the cup, with the augment being securable to the augment in multiple rotational positions. Also, the prosthesis may be configured to facilitate actuation between the unlocked and locked configurations, including moving an instrument to the prosthesis in an access direction that is substantially perpendicular to a rim of the cup.

This disclosure includes apparatus and methods to attach an orthopedic device to a bone. The method can comprise locating a baseplate on a glenoid of a patient, the base plate including at least a first fastener bore, creating a first post hole in the glenoid for locating a first fixation post, the first fixation post including a quasi-spherical head and a porous metal sleeve, and driving the first fixation post through the first fastener bore and into the first post hole. The porous metal sleeve can engage the first post hole and the quasi-spherical head can contact at least the first wall of the first fastener bore to removeably lock the quasi-spherical head to the baseplate. Driving the first fixation post can create an initial compression between the baseplate and the glenoid. The porous metal sleeve can receive bone ingrowth to maintain the initial compression.

A prosthetic system that includes a prosthetic implant and a support structure secured to an inner surface of a cavity of a bone is disclosed. The support structure defines a channel that extends through the length of the support structure. The prosthetic implant is received in the channel, and a portion of the prosthetic implant is secured to an inner surface of the support structure by an adhesive. The support structure may comprise a pair of partially hemispherical components arranged in spaced apart relationship thereby defining the channel between the pair of components.

A method of implanting a prosthetic stemless shoulder implant may include making an incision into a patient's shoulder area of a patient and passing a cutting instrument through a rotator cuff interval of the patient. A central portion of the native humeral head may be resected and removed so that a central void remains. The same or another cutting instrument may be inserted through the rotator cuff interval and into the central void. Medial and lateral portions of the native humeral head adjacent the central void may be resected and removed. A base of a prosthesis may be implanted into a proximal portion of the humerus after passing the base through the rotator cuff interval, and two humeral head portions may be inserted through the rotator cuff interval and coupled to the base and to one another.

System, including apparatus and methods, for ankle fusion using a device for separating a first bone and a second bone of an ankle region. In some embodiments, the device may comprise an expandable spacer including first and second bone-contacting surface regions facing away from one another and configured to be abutted with the first and second bones, respectively. A distance between the first and second bone-contacting surface regions may be adjustable to change the separation of the first and second bones. The first bone-contacting surface region may correspond to a portion of a sphere and may be configured to be disposed at least partially in a concavity formed surgically in the first bone. The expandable spacer offers improved control over the length of the lower limb and the orientation of the foot during ankle fusion surgery.

An implantable prosthetic hip system generally includes acetabular components, femoral components, and tooling for implanting the components. The acetabular components include an acetabular socket and a bushing received within the acetabular socket. The acetabular socket defines a reamer with cutters for preparing the acetabulum. The femoral components generally include a cutter cap, a head cover, and a screw. Tooling includes a cutting bit that is used to cut a flat on the femoral head. The cutter cap is advanced in a cutting action onto the femoral head to remove the sides of the head and the cutter cap is also implanted on the femoral head. The head cover is positioned on the cutter cap, and retained with a coupling screw. The acetabular socket and the head cover are assembled with a bushing therebetween. Methods of implantation are also provided.

A method of performing joint arthroplasty includes accessing a surface on a bone and supporting a stop with the accessed surface. The method includes positioning an instrument at least partially within the stop, the instrument having a body and a punch, the punch including a portion thereof having a shape similar to a shape of a stem of an implant, and rotating the stop with respect to the accessed surface based upon an indicia on one of the body and the stop so as to position the punch rotationally with respect to the accessed surface at a first orientation. The method further includes moving the body axially with respect to the stop to form a cavity in the bone with the punch at the first rotational orientation, the formed cavity having a shape similar to the stem of the implant, and implanting the stem of the implant into the cavity.
