Embodiments of this application relate to the use of porous coating implants to repair soft tissue injuries. Implant frames are coated with a porous coating, such as a titanium porous coating, for example, on both the bone-facing and the soft tissue-facing sides of the implant. The implant may then be sandwiched between the bone and soft tissue so that the bone grows into one side, and the soft tissue grows into the other side.

A spinal bone graft includes one or more cortical bone portions forming a first unit. The first unit includes an engagement surface for contacting bone, and a mating surface. The mating surface forms at least one first undercut. The bone graft also includes one or more cortical bone portions forming a second unit. The second unit includes an engagement surface for contacting bone, and a mating surface. The mating surface forms either at least one second undercut, or at least one connector. In the former, at least one connector is received in each of the first and second undercuts to interconnect the first and second units. In the latter, the at least one connector of the second unit is received in the first undercut of the first unit to interconnect the first unit and second unit.

An annuloplasty implant comprises a plurality of individual wires, each extending in a longitudinal direction of the implant between first and second opposite ends of the implant. A locking unit arranged at at least one of the ends comprises a locking structure connected to the plurality of individual wires, thereby collecting said plurality of individual wires together at at least one of the ends. The locking structure is configured to allow a relative movement between at least two of the plurality of individual wires inside the locking structure.

A flexible bone implant includes a proximal stem having a proximal end, a distal end, and a proximal conduit extending from the proximal end to the distal end of the proximal stem, whereby the proximal conduit is open at both the proximal and distal ends of the proximal stem. The implant includes a distal stem having a proximal end, a distal end, and a distal conduit extending from the proximal end to the distal end of the distal stem, whereby the distal conduit is open at both the proximal and distal ends of the distal stem. The implant includes a flexible hinge interconnecting the distal end of the proximal stem with the proximal end of the distal stem for allowing the proximal and distal stems to flex relative to one another. A proximal stem protective tube is disposed within the proximal conduit of the proximal stem and has a length that matches the length of the proximal conduit, and a distal stem protective tube is disposed within the distal conduit of the distal stem and has a length that matches the length of the distal conduit. The proximal stem, the distal stem and the flexible hinge comprise a unitary structure made of a polymer material.

The present application is generally directed to implantable systems, devices and related methods pertaining to spinal surgery. In particular, the present application discloses a frame and spacer system for inserting into a disc space. The frame and spacer system is of low profile. The frame can receive different fixation devices, including threaded and non-threaded fixation devices.

Bone implants, including methods of use and assembly. The bone implants, which are optionally composite implants, generally include a distal anchoring region and a growth region that is proximal to the distal anchoring region. The distal anchoring region can have one or more distal surface features that adapt the distal anchoring region for anchoring into iliac bone. The growth region can have one or more growth features that adapt the growth region to facilitate at least one of bony on-growth, in-growth, or through-growth. The implants may be positioned along a posterior sacral alar-iliac (SAI) trajectory. The implants may be coupled to one or more bone stabilizing constructs, such as rod elements thereof.

A medical implant includes a body and a porous structure attached to the body. A boss integral with the body extends outwardly from a surface of the body. The porous structure has a surface that cooperates with the boss of the body to prevent pullout of the body from the porous structure. In fabricating the medical implant, the body and the porous structure are formed separately and subsequently secured together.

Particular aspects provide novel devices for bone tissue engineering, comprising a metal or metal-based composite member/material comprising an interior macroporous structure in which porosity may vary from 0-90% (v), the member comprising a surface region having a surface pore size, porosity, and composition designed to encourage cell growth and adhesion thereon, to provide a device suitable for bone tissue engineering in a recipient subject. In certain aspects, the device further comprises a gradient of pore size, porosity, and material composition extending from the surface region throughout the interior of the device, wherein the gradient transition is continuous, discontinuous or seamless and the growth of cells extending from the surface region inward is promoted.
