摘要:
An implant device identifiable after implantation is provided. The implant device includes a spinal interbody implant including an implant body including at least one orientation marker rod. Each of the at least one orientation marker rod has a series of physical encodings discernible by an imaging system. The physical encodings encode a respective set of data.
摘要:
A radiolucent intervertebral prosthesis is implanted in an environment that has been prepared in a manner which enhances radiopacity of the prosthesis and/or the environment. A liquid, powder, or other fluid radiopaque (RO) material, such as iohexol, is introduced into an implantation site, either by directly introducing the material into the site and/or by applying the material to a surface of the implant. The presence of the RO material in the implantation site provides contrast with the material of radiolucent prosthesis while the implantation site is being radiographically imaged, e.g. during fluoroscopic visualization while the prosthesis is being implanted. During implantation, the RO material helps the physician view and manipulate the implant, and after the implantation is complete, the RO material will be resorbed or otherwise lost from the implantation site so that the area returns to a radiolucent condition to facilitate subsequent radiographic imaging when needed.

An orthopedic implant system includes a wedge implant. The implant includes a body having an upper surface extending generally in a first plane. The upper surface has a first plurality of longitudinal grooves and a second plurality of transverse grooves extending therealong. Portions of the upper surface extend between adjacent longitudinal grooves and transverse grooves form individual peaks. A lower surface extends generally in a second plane, parallel to the first plane. The lower surface has a third plurality of longitudinal grooves and a fourth plurality of transverse grooves extending therealong. Portions of the lower surface extend between adjacent longitudinal grooves and transverse grooves form individual peaks.
摘要:
A spinal implant comprises an implant body extending between an anterior surface and a posterior surface and includes a first vertebral engaging surface and a second vertebral engaging surface. The implant body includes an inner surface that defines at least one cavity that is oriented to implant a fastener oblique relative to a lateral axis of a subject body and adjacent an intervertebral space of the subject body. The implant body includes an oblique surface that defines at least one opening disposed in substantial alignment with the at least one cavity. Systems and methods are disclosed.

Intervertebral fusion implant cages (10) and methods of fabrication are described herein. The cages (10) may be used to assist with fusing together adjacent vertebrae when a displaced or damaged spinal disc is surgically removed. The cages include windows that allow the bone graft to grow from one vertebra through the cage and into the adjacent vertebra (e.g., cervical vertebrae). The cages include a number of features which enhance its performance during use.
摘要:
An implant includes a first plate and a second plate, a first wedge member and a second wedge member spaced from the first wedge member that couple the first and second plates together. The first and second wedge members configured to translate along the first and second plates from a first contracted configuration into a second separated configuration. The implant includes an actuation member coupled to the first wedge member and the second wedge member. The actuating member defines a flange extending toward the first and second plates. The actuation member configured to move the first and second wedge members from the first contracted configuration into the second separated configuration so that the first and second plates separate from each other
摘要:
An assembly for replacing a vertebral disc. The assembly includes an implant and a device for positioning the implant between two adjacent vertebrae. The implant includes a body having an internal compartment enclosed by an outer wall, and a skeleton coupled to the body. The device includes a cannula, a container coupled to the cannula, the container having a first end and a second end, a plunger threadingly coupled to the cannula and to the first end of the container, and a conduit coupled to the second end of the container and in fluid communication with the body of the implant. The implant is positioned within the cannula in an undeployed state and is deployed within a vertebral disc to receive a biological fluid in a second state.
摘要:
A low friction resurfacing implant system including a first implant component (20) having a first bearing surface (26) and a first engagement surface (24). The first engagement surface is located opposite the first bearing surface. The first implant component has a leading edge and a trailing edge. The first implant component includes teeth (22) that extend from the first engagement surface. The teeth are arranged in a plurality of rows. The teeth in adjacent rows are offset from each other.
摘要:
A spinal implant comprises a first member defining a longitudinal axis and including a wall that defines an axial cavity and at least one lateral opening configured for disposal of an instrument. A second member is configured for disposal with the axial cavity and includes a wall having an axial surface disposed along a thickness thereof. The axial surface defines at least a portion of an axial opening and includes a plurality of gear teeth disposed therealong. The instrument is engageable with the teeth to axially translate the second member relative to the first member. Systems and methods of use are disclosed.
摘要:
The present disclosure relates to a spinal implant (lOOC). The spinal implant may be used for lateral insertion into an intervertebral disc space. For example, the spinal implant may include a spacer body (102) to which a plate (106) is fixed. The intervertebral spacer body may include a pair of opposite sides (104) having a pyramid-shaped teeth (118) to fuse to bone. The plate defines at least one upper and lower borehole (110F1, 110F2) that each receives a screw (108). Each screw attaches the plate to a vertebral body between which the intervertebral spacer body is inserted. The boreholes may include locking threads (112) that are adapted to lock the screws into place by engaging complementary locking threads of head of the screw.
