A spinal implant (e.g. interbody spacer) with one or more apertures for the containment of bone graft or bone graft substitute. The implant may be packed with graft material prior to or subsequent to implantation. The implant has an integrated mechanism to reduce the volume of the bone graft aperture thereby compressing or repositioning graft material.

A variable angle blade augment including an augment component and a blade component. The blade component includes a buttress portion and a neck portion, with the neck portion having a body segment and a face segment that is contoured for mating engagement with an outer surface of the acetabular shell. The augment component has a first opening sized and shaped to receive insertion of the body segment, and which is also sized to accommodate selective adjustment of, when the body segment is positioned in the first opening, linear and angular orientations of the blade component relative to the augment component. Additionally, the body segment has a length that is sized to facilitate direct contact of the face segment with the acetabular shell when the variable angle blade augment is in an assembled configuration. Further, cement can be injected into the internal cavity to unitize the connection between the acetabular shell and the blade component.

The invention relates to an artificial hip joint implant (1), having a hip head (2), a femur neck (3) and a femur shaft (4) connected thereto, wherein the femur shaft (4) has an upper part (41) facing the shaft attachment (3) and a lower part (42), and the upper part (41) is connected to the lower part (42) by a length-adjusting device (51, 52, 6).

A variable angle blade augment including an augment section and a separate plate or blade segment. According to some embodiments, a first connector of the blade segment and a socket capture mechanism of the augment section provide a ball and socket type joint. Additionally, the socket capture mechanism may be structured to allow for linear displacement of the first connector relative to at least one axis of the socket capture mechanism. By allowing for at least pivotal and linear relative displacement of the augment section and the blade segment, the variable angle blade augment may improve the ability to optimally position a buttress augment against a prosthetic acetabular shell. Moreover, the variable angle blade augment may provide the ability to utilize components of an implantable medical device after stabilizing the components to a bone structure of a patient.

Disclosed is an implantable artificial intervertebral disc joint replacement device for implantation between adjacent vertebral bodies. The device allows selective positioning of a disc implant element and comprises translatable surfaces, a mechanism for translation, a means for bone attachment, and an integrated disc implant. The device can be used in the lumbar, thoracic, and cervical regions of the spine in single or multi-level configurations. When implanted in a patient, the device includes an upper (cranial) component and a lower (caudal) component attached to the vertebral body above and below the replaced intervertebral disc respectively, with the joint implant integrated into the translatable surfaces. Following implantation, precise positioning of the joint implant within the intervertebral space with respect to the spinal axis is then adjusted based upon the particular anatomical and functional needs of the individual patient to satisfy spinal range of motion and stability requirements.

An arthroplasty plate and method of use to repair a fractured end of a bone are described. The arthroplasty plate comprises a fixation plate arranged to be secured to a surface of a bone and a connector assembly comprising a barrel extending from the fixation plate and having a bore which opens through the fixation plate. A connector rod is arranged to slide within the bore of the barrel. An articulation component comprises a bearing surface coupled to or arranged to couple to an end of the connector rod which extends from the barrel away from the fixation plate. The connector assembly incorporates an adjustment mechanism arranged to cause the connector rod to slide into or out of the barrel and a locking mechanism arranged to lock the position of the connector rod within the barrel to rigidly space the articulation component apart from the fixation plate.

The present disclosure is directed to a modular shoulder prosthesis measuring device having an adjustable radial offset provided by relative rotation of an adapter interdisposed between the stem and the head. Specifically, the interface configuration between the stem and the adapter, as well as between the adapter and the head are designed such that relative positioning of these components provides a continuous adjustment in the radial offset. Indicia are provided to precisely determine the magnitude and direction of the adjustment being made.

Prostheses, systems, and methods are provided for replacement of natural facet joints between adjacent vertebrae using polyaxial attachment mechanisms for securing the prostheses to the vertebrae. A cephalad prosthesis attached to a superior adjacent vertebra replaces the inferior half of a natural facet joint. A caudal prosthesis attached to an inferior adjacent vertebra replaces the superior half of a natural facet joint. Both the cephalad and caudal prostheses are configured with artificial facet joint structures that include articulating surfaces that cooperate and form an artificial articular configuration. The polyaxial attachment mechanism permits adjustment of the position of the artificial facet joint structure along more than one axis at or after the time the cephalad or caudal prosthesis is attached to a vertebra.

An expandable fusion device is capable of being installed inside an intervertebral disc space to maintain normal disc spacing and restore spinal stability, thereby facilitating an intervertebral fusion. The fusion device may include a body portion, a first endplate, and a second endplate, the first and second endplates capable of being moved in a direction away from the body portion into an expanded configuration or capable of being moved towards the body portion into an unexpanded configuration. The fusion device is capable of being deployed and installed in both configurations.

A trial insert having a first member having an engagement channel extending from a bottom surface towards a top surface and along a first direction that extends from a first end to a second end. The trial insert has a second member having an engagement member extending away from a top surface and along a second direction that extends from a first end to a second end, where the engagement member is received within the engagement channel, and where the first member is translatable relative to the second member along a longitudinal axis of the trial insert.
