Provided is a variable lordotic expanding implant with a centralized graft deployment delivery channel (tube) with (or without) an expanding footprint mesh component which is deployed by graft material injection.

Various embodiments of intervertebral implants, anchoring devices for intervertebral implants, and implantation instrumentation are provided, along with various embodiments of methods for using one or more of the devices. Some embodiments of an anchoring device have a body comprising at least one curve and a rigid plate elongated along a longitudinal axis so that its front end enters at least one vertebra while its rear end remains in the passage of an implant. In some embodiments, the plate comprises at least one longitudinal slot separating at least one posterior portion of the plate into two branches, with at least one branch comprising at least one withdrawal stop configured to retain the device in the implant.

A separate nub component between the plate and an intervertebral fusion cage, wherein the nub is attached to the plate. The nub lessens the undesired pivotal movement of the plate. It is believed that when the nub fits snugly between the endplates of the adjacent vertebral bodies, it acts as a stop against the undesired pivotal movement of the plate.

An expandable implant is disclosed. The expandable implant includes a base member having a top surface and a bottom surface opposite the top surface, and an adjustable member adjustably coupled to the base member and movable between a first, collapsed position, and a second, expanded position. The adjustable member has a top surface and a bottom surface opposite the top surface. The top surface of the adjustable member and the bottom surface of the base member form a first angle while the adjustable member is in the first, collapsed position, and the top surface of the adjustable member and the bottom surface of the base member form a second angle while the adjustable member is in the second, expanded position. The first angle is different from the second angle.

Various embodiments disclosed herein relate to stemmed and stemless humeral anchors for use in shoulder arthroplasty procedures. For example, the humeral anchor can include a first end, a second end, and an interior surface extending between the first end and the second end. The interior surface can be disposed about a recess disposed between the first end and the second end. The recess can be configured to secure a coupling of a shoulder articular body directly to the interior surface.

An expandable implant includes an upper plate configured to receive a first anchoring member, an upper support mechanically coupled to the upper plate, a lower plate configured to receive a second anchoring member, and a lower support mechanically coupled to the lower plate. The implant further includes a control member including a shaft and configured to control movement between the upper support and the lower support, a front portion configured engage the upper support and the lower support and further configured to receive the head of the control member, and a rear portion configured engage the upper support and the lower support and further configured to engage a portion of the shaft, wherein turning the control member causes the front portion to move in a direction towards the rear portion, such that the upper support moves relative to the lower support in a direction away from the lower support.

The invention relates to a modular humeral prosthesis for an inverse shoulder prosthesis, comprising an anatomical shaft (1) and a separable epiphyseal head (2) which may be angularly orientated by rotation about the longitudinal axis (XX) of the anatomical shaft. The anatomical shaft and the epiphyseal head comprise complementary angular indexing means (11, 28) for relative rotational fixation.

An expandable interbody implant adapted for insertion at least into a disc space, between two adjacent vertebrae of a spine. An upper member and a lower member are pivotally connected at least by a drive link. A bone graft storage portion packed with a selected volume of bone growth material. A translational wall is provided between the bone graft storage portion and a trailing end of the implant. An actuator engages the bone graft storage portion, pushing it forward into engagement with the drive link, which pivots upward, moving the upper member upward away from the lower member. Upward movement of the upper member raises the translational wall to a position to assist in retention of the selected volume bone graft material within the hollow portion of the bone graft storage portion. Upward rotation of the drive link brings a face thereof into contact with a front of the bone graft storage portion, thereby retaining near constant volume of the bone graft material.

An expandable implant includes a top support configured to engage a first portion of vertebral bone, a bottom support configured to engage a second portion of vertebral bone, and a control assembly coupled to the top support and the bottom support and configured to control relative movement between the top support and the bottom support. The control assembly includes a control member including a head and a body portion. The head includes a recess and the body portion includes at least one access port in fluid communication with the recess to enable delivery of fluid to an interior of the implant via the recess and at least one access port.

A semi-condylar artificial knee joint includes a femoral prosthesis and a tibial prosthesis, and the cross-section of the tibial prosthesis is of a kidney-like type. The tibial prosthesis is disposed at one side of the tibial plateau intercondylar eminence and is located below the femoral prosthesis. The artificial knee joint further includes a locating pin for fixing the tibial prosthesis. The bottom surface of the tibial prosthesis is provided with a prosthetic notch, and below the tibial prosthesis is provided with a tibial notch. The prosthetic notch corresponds to the tibial notch, and together forming a limiting hole for accommodating the locating pin. The cooperation between the locating pin and the limiting hole can ensure relative position stability and balance between the tibial prosthesis and the tibial plateau intercondylar eminence.
