A delivery device includes a guide tool and an impact tool. The guide tool includes an elongate body formed with a longitudinal guide channel, whose inner perimeter is made to complement an outer contour of an implant. The elongate body is formed with a longitudinal impact-tool channel, whose inner perimeter is made to complement an outer contour of the impact tool.

Surgical methods and tibial implants for accommodating the anterior cruciate ligament during unicompartmental or bi-unicompartmental knee arthroplasty procedures.

The implant (1) includes at least two assembled components, at least a first component (3) is intended to be movable relative to at least a second component (2). The method includes the steps of: designing the implant (1) such that the second component (2) at least partially envelops the first component (3) and that at least one connecting bridge (4) connects the first component to the second component, each bridge (4) having a section such that it is frangible; making the implant (1) using a so-called 3D printing method, includes depositing on a platen, a layer of powdered fusible material, causing the particles of this layer of powder to fuse in locations corresponding to the shape which, at this layer, the first component (3, 23, 33, 53, 63) and/or the second component (2, 22, 32, 52, 62) and/or the at least one bridge (4, 24, 54, 64) have, depending on whether the first component, the second component and/or said bridge are present at the section the implant to be formed has at the layer; repeating these operations until the implant (1, 21, 31, 51, 61) is fully constructed, and eliminating the powder particles that are not fused.

An orthopedic prosthesis for use in a hip replacement surgery. The orthopedic prosthesis includes a metallic foam shell and a metallic core. The metallic core includes a neck configured to receive a femoral head component and a stem extending through the metallic foam shell.

The present invention provides methods of forming flexible implant devices and U-bridge implants that drive into curved trajectories to enhance implant fixation in bone. The curved drilling trajectories avoid regions of low bone mineral density, such that flexible implants and/or U-bridge implants driven into the curved drilling trajectories are anchored in regions of high bone mineral density to improve the stability of bone fixation. The flexible implants and U-bridge implants are suitable for several applications, including but not limited to spinal fixation, orthopedic bone fixation, and neurosurgery.

A fusion cage may include an upper endplate directly hinged to a lower endplate. The fusion cage may be adjustable to provide various angles between the endplates. An insert may be coupled between the endplates to lock the endplates at a selected angle. Fasteners may extend through the fusion cage into adjacent bone portions. An instrument may couple to an endplate so that the hinged-together endplates may be inserted between bone portions. The instrument may be used to adjust the angle between the endplates and to couple the insert between the endplates.

An implant having an upper support body and a lower support body that are coupled together by use of pinions integral to the upper support body and apertures integral to the lower support body. A dual directional driver is rotatably coupled to a forward spacer and a rear spacer, wherein the implant forms a compact arrangement for ease of insertion allowing a posterior surgical approach for placement of the spinal implant for interbody fusion allowing the implant to be inserted through a small incision and rotation of the dual directional driver will cause movement of the upper support body an equal distance from the lower support body to increase the implant in size in situ.
