Humeral head implant system
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.
System and method for repairing articular surfaces
A joint replacement system for repairing an articular surface of a first bone of a joint includes an anchor portion and an implant portion. The anchor portion includes an anchor to be secured to the bone, and an anchor fixation head including a bone-facing surface (BFS) extending radially outward from the anchor and an implant facing surface (IFS) extending from a periphery of the BFS. The implant portion is formed from a material (e.g., CoCr) more dense than the material of the anchor portion (e.g., Ti) and includes a fixation cavity to receive at least a portion of the anchor fixation head (AFH), the fixation cavity includes an anchor facing surface (AFS) configured to form a frictional connection with the IFS, and a load bearing surface having a contour for articulating against a cooperating articulating surface of a second bone of the joint.
EXPANDABLE INTERVERTEBRAL IMPLANT
An implant including first and second end plates, each of which defines at least one anterior ramped surface and at least one posterior ramped surface. A posterior actuator is positioned between the first and second end plates and has guiding ramp surfaces which correspond with the posterior ramped surfaces. An anterior actuator is positioned between the first and second end plates and guiding ramp surfaces which correspond with the anterior ramped surfaces. An actuator assembly extends between the posterior actuator and the anterior actuator and is configured to selectively move the posterior actuator and the anterior actuator simultaneously, move posterior actuator independently of the anterior actuator, or move the anterior actuator independently of the posterior actuator.
Modular polymer femoral components with metallic inserts
A system for converting a first joint prosthesis to a second joint prosthesis in-situ includes a plurality of inserts having a bone interface side and a component facing side and a plurality of articulating components having a cavity configured to receive at least one of the plurality of inserts. The plurality of inserts may be unicompartmental, bicompartmental, or tricompartmental. The inserts may be made of metal and may have a bone contacting surface made of a porous metal. The plurality of articulating components may be unicompartmental, bicompartmental, or tricompartmental. The articulating components may be sized and shaped to cover one or more of the plurality of bone interface components and span a distance therebetween. The articulating components may be made of a polymer.
Multi-piece intervertebral implants
Intervertebral implants for implanting into an intervertebral space are provided. The implants can comprise one or more layers that are operably attached to one another. An implant can comprise a first layer having a first mating surface that mates with a second mating surface of a second layer. The first mating surface and the second mating surface can have features that allow them to complement each other. The implants can include one or more bore holes for receiving a fixation member. The bore holes can be horizontal, vertical or diagonal. In some cases, the bore holes will be blind bore holes.
Foot prosthesis comprising a damping element
The present invention relates to a foot prosthesis (1, 61) comprising a heel (6, 71) and a tip (7, 62), both of which can bear on the ground, and an ankle support (2, 67), characterised in that the prosthesis also comprises at least one damping element (10, 76) designed to be at a distance from the ground.
Helicoil interference fixation system for attaching a graft ligament to a bone
A helicoil interference fixation system comprising: a helicoil comprising a helical body comprising a plurality of turns separated by spaces therebetween, the helical body terminating in a proximal end and a distal end, and at least one internal strut extending between at least two turns of the helical body; and an inserter for turning the helicoil, the inserter comprising at least one groove for receiving the at least one strut; the helicoil being mounted on the inserter such that the at least one strut of the helicoil is mounted in the at least one groove of the inserter, such that rotation of the inserter causes rotation of the helicoil.
Laser-produced porous structure
The present invention disclosed a method of producing a three-dimensional porous tissue in-growth structure. The method includes the steps of depositing a first layer of metal powder and scanning the first layer of metal powder with a laser beam to form a portion of a plurality of predetermined unit cells. Depositing at least one additional layer of metal powder onto a previous layer and repeating the step of scanning a laser beam for at least one of the additional layers in order to continuing forming the predetermined unit cells. The method further includes continuing the depositing and scanning steps to form a medical implant.
Modular endoprosthesis shaft system with rotation element
The invention relates to an endoprosthesis shaft system for elongate bones, comprising an anchoring part (10) and a shaft (1), which is formed from module elements that can be coupled by means of a plug-in connection (45), wherein a mutual rotation of the elements along the shaft (1) is adjustable and is blocked by means of an anti-rotation mechanism. In order to adjust the rotation, a rotation piece (5) is provided as a further module element, which has a self-contained rotation adjustment device (6) and a clamping device (7) as a mechanism for blocking the rotation. The rotation piece (5) comprises two end faces for the plug-in connection (45) and a sleeve (77). The invention provides, with the rotation piece, a particular module element for the shaft, which as a structural unit allows both an adjustment of the rotation and a blocking against undesired rotation in a self-contained unit.
ANGLED BASEPLATE FOR HUMERAL AND GLENOID ARTICULAR SURFACE IMPLANT SYSTEMS AND METHODS
The present disclosure provides a glenoid implant system for a reverse shoulder implant system that includes a glenoid implant having a center post, and also includes an angled baseplate comprising a bone facing surface to face an implant site prepared in a glenoid region of a patient, and an implant facing surface to face and engage the glenoid implant and receive the center post of the glenoid implant, wherein the implant facing surface being at an angle with respect to a centerline of the bone facing surface.
