摘要:
A resorbable, flexible implant in the form of a continuous macro-porous sheet (42) is disclosed. The implant (42) is adapted to protect biological tissue defects, especially bone defects (49) in the mammalian skeletal system, from the interposition of adjacent soft tissues (57) during in vivo repair. The membrane (42) has pores (46) with diameters from 20 microns to 3000 microns. This porosity is such that vasculature (61) and connective tissue cells derived from the adjacent soft tissues (57) including the periosteum (64) can proliferate through the membrane (42) into the bone defect (49). The thickness of the sheet (42) is such that the sheet (42) has both sufficient flexibility to allow the sheet (42) to be shaped to conform to the configuration of a skeletal region (55) to be repaired and sufficient tensile strength to allow the sheet (42) to be so shaped without damage to the sheet (42). The sheet (42) provides enough inherent mechanical strength to withstand pressure from adjacent musculature and does not collapse.

Anchoring devices, intervertebral implants and intervertebral systems are disclosed. In preferred configurations, these various objects share the feature of comprising or cooperating with an anchoring device (1) having a body comprising at least one curved plate (10) elongated along a longitudinal axis (L), designed to be inserted through a passage (21) crossing at least a part of implant (2), in order to penetrate into at least one vertebral endplate and attach implant (2) onto this vertebral endplate by means of at least one stop retaining the implant, characterized in that the curvature of said body is oriented in the width of plate.
摘要:
An acetabular prosthetic device (10) comprising at least one acetabular augment (14) coupled to an acetabular cup (16) by an augment coupling element (32) to secure the acetabular prosthetic device (10) in place wherein the acetabular cup (16) comprises a shell (18) having at least one groove (28) formed on the outer surface (26) thereof to slidably receive the augment coupling element (32) therein and the acetabular augment (14) comprises an augment body (34) configured to engage the shell (18) and the ilia bone (IB) such that the augment coupling element (32) is moved along the groove (28) to position the acetabular body (34) to engage both the shell (18) and ilia bone (IB) to secure the acetabular prosthetic device (10) in place.
摘要:
A device for processing vertebral members having a spacer (10), a delivery device (80), and a deployer (7). The spacer (10) includes at least first and second members (20, 30) with the first (20) having at least one angled section (25, 26) and a contact surface (27, 28), a second member (30) having at least one angled section and a contact surface. The delivery device (80) is attached to at least one of the first (20) and second members (30). The first and second members (20, 30) being movable relative to one another for the angled sections to contact and expand the height of the device. The device is positionable between a first closed orientation having a first height, a second open orientation having a second height greater than the first height, and gradations therebetween. Methods of spacing vertebral members using the spacer are also disclosed.
摘要:
A method of manufacturing a composite interbody device is provided, comprising: assembling superior and inferior endplates: wherein the surface features increase surface area of the bone interface layer, to optimize contact with bone at an implant site; and forming a porous core interface layer on the central barrier layer opposite the bone interface layer; diffusion bonding under heat and pressure the core interface layer with the central barrier layer and the bone interface layer coating the bone interface side with hydroxyapatite; placing the inferior and superior endplates in a mold, on each side of a core cavity, with the core interface layers facing the core cavity and the bone interface sides facing away from the cavity; and injection-molding molten plastic into the core cavity, to form a plastic core between the endplates and bonded with core interface sides of the core interface layers; wherein molten plastic extrudes into pores of the core interface layers, to bond with the endplates.
摘要:
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.
摘要:
A joint prosthesis system, specifically a shoulder prosthesis, for shoulder replacement, revision and repair. The implants provide fixation into the best bone available to a surgeon. The implants are used in a superior-inferior and anterior-posterior construct forming a type of cross or X-shape. The implants allow for interchangeability of the articulating component as well as rotational orientation. The systems will allow for augments to accommodate bone loss. The implants may allow for additional security using screws or anchors inserted into the scapula.
摘要:
The subject matter of the invention is a tool (12) for a spinal implant, with a rod-like lever-rotator (42) and a handle (44) attached thereto, wherein the lever-rotator (42) has a number of teeth (46) distributed over the circumference at the distal end thereof and wherein each tooth (46) is aligned coaxially. Developing a tool such that the spinal implant can be implanted and distracted in a simple and precise fashion is achieved by virtue of the fact that each tooth (46) is embodied to be so long that it can simultaneously engage into a corresponding wall tooth (28) of a first lever receptacle (26) and into a corresponding wall tooth (32) of a second lever receptacle (30) of the spinal implant (10).
摘要:
A system for sizing a prosthetic implant within a knee joint, the system comprising a femoral portion couplable to a distal end of a femur; a tibial portion couplable to a proximal end of a tibia; a sensor housing couplable to or integrated with the femoral portion or the tibial portion and including one or more force or pressure sensors, the one or more sensors configured to measure a force or a pressure produced within the knee joint, the force or pressure generated, at least in part, by soft tissue adjacent to the knee joint; and a plurality of shims configured to engage the femoral portion or the tibial portion and adjust the force or pressure produced, at least in part, by the soft tissue adjacent to the knee joint.
