A spinal implant comprises an implant body extending between an anterior surface and a posterior surface. The implant body includes a first vertebral engaging surface and a second vertebral engaging surface. The implant body includes an outer surface that defines an oblique surface. A wall is connectable with the implant body and translatable relative to the oblique surface. Systems and methods are disclosed.

Systems and methods and augments for supporting an acetabular shell at a hip bone. An example system of modular augments can include first and second augments, each having a body extending from a respective first end portion to a respective second end portion. The first augment second end portion can include a first coupling element and the second augment first end portion can include a second coupling element. Together the first and second coupling elements can form a coupling mechanism to join the first and second augments together. In some examples, the coupling mechanism can include a bulbous tip portion and a recess to receive and retain the bulbous tip portion.

A spinal implant includes an implant body extending between an anterior surface and a posterior surface. The implant body includes a first vertebral engaging surface and a second vertebral engaging surface. The implant body defines a cavity. A plate is connectable with the implant body via a coupling member adjacent the cavity and is translatable relative thereto. The coupling member has a portion including a frangible torque limit. The plate defines at least one opening oriented to implant a fastener with tissue. Systems, spinal constructs, surgical instruments and methods are disclosed.

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.

The present application relates to an endoprosthesis, including a first member which is connected to a patient's bone; a second member which is adjustably coupled to the first member by a coupling device; wherein the coupling device is configured to generate a movement of the second member relative to the first member. The present application also relates to an artificial joint including such an endoprosthesis and to an endoprosthesis placement system including such an endoprosthesis or artificial joint and a projection device which is configured to project visible light markings, acquired from pre-operational and/or intra-operational patient data, onto the patient and/or the endoprosthesis, thus enabling visible alignment markings of the endoprosthesis to be aligned with respect to projected visible light markings so as to allow a proper adjustment of the endoprosthesis.

An assembly for attachment to a first implant component has a size and shape of a second implant component to be implanted together with the first implant component. The assembly includes a first body and a second body removably connected to the first body. In a temporary configuration, the first and second bodies are prevented from separating while the first and second bodies permit relative movement therebetween. A modular kit includes a plurality of the first bodies each having a different size or shape, and a plurality of the second bodies each having a different size or shape. A method of assembling the assembly includes removably connecting the first body to the second body, such that the first and second bodies are prevented from separating while permitting relative movement therebetween, and positioning the assembly on the first implant component.

An assembly for attachment to a first implant component has a size and shape of a second implant component to be implanted together with the first implant component. The assembly includes a first body including a plug having a projection, and a second body including a recess having an internal surface defining at least one indentation. In a temporary configuration, when the plug is disposed within the recess and the projection is disposed at least partially within one of the at least one indentations, the first and second bodies are removably connected such that the first and second bodies are prevented from separating. A method of assembling the assembly includes removably connecting the plug of the first body into the recess of the second body by locating the projection within an indentation, such that the bodies are prevented from separating, and positioning the assembly on the first implant component.

Disclosed is an expandable interbody fusion implant that is configured to have an initial configuration having a first footprint width suitable for being inserted into an intervertebral space and an expanded configuration having a second footprint width that is greater than the first footprint width. The implant may include a first body member and a second body member that is pivotally coupled to the first body member. The implant may be expanded using an inflatable balloon. The implant may be expanded bilaterally such that both body members rotate relative to the other or the implant may be expanded unilaterally such that one of the body members rotates relative to the other.

The application is directed to devices and methods where one or more magnetic or magnetizable implants provides therapeutic benefits to a patient. The implant may be useful for expanding the range of motion of joints or dynamically providing different responses to changing conditions in the body where the implant is placed. An electromagnet is placed on or in a bone on one side of a joint, and another electromagnet or magnetically active material is placed on or in a bone on the opposing side of the joint. The electromagnet may be continuously energized to relieve pressure in the joint space, or may be energized in response to forces applied to the joint.
