An acetabular liner having a closed first end, an open second end, and a liner wall having a distal peripheral edge. The acetabular liner wall can include an interior surface, an exterior surface configured to be received within an acetabular shell, a first cutout through the liner wall, a second cutout parallel to the first cutout and through the liner wall, and a third cutout in the interior surface partially through the liner wall, the third cutout extending between the first and second cutouts, and at least one movable tab extending from the peripheral edge inwardly towards an axial center of the liner and having sidewalls defined by one of the sets of cutouts, the tab comprising at least one projection on an exterior surface of the tab configured to removably secure to a portion of an acetabular shell.

A bone graft containment device includes a plurality of cage segments connected to one another along a longitudinal axis, each of the cage segments connected to an adjacent one of the cage segments via a connection which permits movement of the cage segments relative to one another so that the bone graft containment device is deformable to a desired configuration for placement within a target space of a bone, each cage segment extending along from a first end to a second end and including a channel extending therethrough so that channels of the plurality of cage segments, in an initial configuration, are aligned along the longitudinal axis, the channels configured to be packed with a bone graft material.

An elbow prosthesis according to the present teachings can include a stem structure and an articulating component. The stem structure can be operable to be positioned in a bone of a joint. The stem structure can include a stem portion that is operable to be positioned in the bone and a C-shaped body portion having a first retaining mechanism formed thereon. The articulating component can have a second retaining mechanism formed thereon. One of the first and second retaining mechanisms can comprise an extension portion and a first anti-rotation portion. The other retaining mechanism can comprise a receiving portion and a second anti-rotation portion. The articulating component can be advanced from an insertion position to an assembled position, such that the first and second mechanisms cooperatively interlock to inhibit translation and rotation of the articulating component relative to the C-shaped body portion of the stem structure.

A humeral head implant system includes a head component including a first articulating surface, a second bottom surface extending from the first spherical articulating surface, a first cavity extending a first distance into the head component from the second bottom surface, and a second cavity extending into the head component along a cavity axis. The head component defines a head axis extending through a center of the first articulating surface parallel to the cavity axis. A base component defines a slot extending from a first width to a second width. An insert component includes an insert body, a first engagement feature, and a slot engagement feature. The first engagement feature is received in the second cavity along the cavity axis. The insert body has an insert thickness less than the first distance, and the slot engagement feature slides into the slot in a direction transverse to the cavity axis.

An insert for use in a knee prosthesis is disclosed. In one embodiment, the insert includes a medial compartment and a lateral compartment. The medial compartment includes a top surface having a concave surface or curve with a more posterior sulcus and increased anterior lip. The lateral compartment includes a top surface having at least a segment or portion with a convex surface or curve. Thus arranged, the insert is arranged and configured to provide improved stability for varying grades of PCL deficiencies compared to existing inserts that have a mid-line sulcus and lateral convexity. In addition, the insert provides improved lateral posterior translation compared to existing designs with a concave or flat lateral articulation that lack a lateral posterior convexity.

A surgical implant and a surgical kit. The surgical implant has a body portion comprising a first hole formed in an exterior surface of the body portion, a second hole adjacent the first hole, and at least one through-hole within the body portion and extending entirely thought a depth of the body portion extending entirely thought a depth of the body portion. The implant has a central opening abutting the body portion and extending through the body portion. The first hole has a first sidewall and a first cavity in the body portion, the second hole has a second sidewall and a second cavity in the body portion, and the first cavity and the second cavity have an interconnected opening there between. The surgical kit includes the surgical implant and an intervertebral insertion device.

A method of implanting a medical implant includes resecting a long bone along a shaft of the bone so as to form a resected surface and remove a metaphysis of the bone. A tapered bore is reamed through the resected surface of the long bone and into an intramedullary canal thereof. A tapered portion of a stem of a medical implant is fully seated within the tapered bore so as to form a press-fit between the tapered portion of the stem and the long bone and so that a collar disposed at an end of the stem is offset from the resected surface so as to form a gap between the resected surface and the collar.

This invention corresponds to a prosthesis for total or hip resurfacing replacement, which comprises a prosthetic femoral head made of highly cross-linked polyethylene, with a diameter ranging from 38 mm to 64 mm, to articulate with a cup or acetabular component made of metal. When the invention applies to total hip replacement, the polyethylene head includes a metal core, which contains inside the female counterpart (14) to mate with the male counterpart (13) of a Morse taper, located at the upper end of the femoral component. The use of this type of head for total hip replacement, articulated with an ultra-polished acetabular cup, reduces the risk of dislocation, transmits less angular and torque forces to the Morse taper than large metal heads, and avoids the problems related to the metal-metal bearing or with the use of large metal heads with thin polyethylene. When the invention relates to hip resurfacing replacement, the highly cross-linked polyethylene femoral head has a lower polyethylene extension or stem with or without internal metal reinforcement (151) or a metal stem integrated into a metal-back (152). Using these types of heads for hip resurfacing replacement heads eliminates the problems associated with metal-on-metal resurfacing replacements.

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 spinal implant for placement between vertebral bodies includes a first member for engaging one of the vertebral bodies, a second member for engaging an opposing one of the vertebral bodies, and at least one extendable support element for inducing movement of the entire first member away from the second member. The first member is connected to the second member such that the first member moves away from the second member by a larger distance at a first end of the implant than at a second end of the implant. A connecting member may connect the first and second members together at the second end of the implant. The connecting member may include one or more rotatable linkages, or the connecting member may be an extension of one of the first and second members slidably received within a track defined within the other of the first and second members.
