The three-dimensional lattice structures disclosed herein have applications including use in medical implants. Some examples of the lattice structure are structural in that they can be used to provide structural support or mechanical spacing. In some examples, the lattice can be configured as a scaffold to support bone or tissue growth. Some examples can use a repeating modified rhombic dodecahedron or radial dodeca-rhombus unit cell. The lattice structures are also capable of providing a lattice structure with anisotropic properties to better suit the lattice for its intended purpose.

The present invention pertains to the field of biomaterials for covering and protecting bone grafts/biomaterials, and relates more specifically to a titanium mesh covered with a biocompatible polypropylene film that aims to increase bone volume using biomaterials or using grafts in their most varied forms, such as autogenous bone (bone from the individual), allogenous bone (bone from other individuals of the same species), and xenogenous bone (bone from individuals of a different species) for the subsequent installation of osteointegrated implants. When the claimed mesh protected with a polypropylene film is used, with the film blocking the holes, the materials used to increase the volume do not pass through the holes of the mesh, as they are blocked by the polypropylene film, making these meshes 100% waterproof. This makes it easy to remove the mesh and, as there is no penetration of material through the holes, the implants are installed over a large amount of bone tissue. When using the titanium mesh with the polypropylene film, in contrast to when it does not have this protection, it does not need to be completely covered by surgical flaps, facilitating the surgical technique and thus avoiding post-operative complications due to exposure that often occurs with unprotected meshes. In addition, it is advantageous that the mesh can be kept intentionally exposed to the mouth environment, placed over the materials used to achieve bone volume augmentation, regardless of the materials used underneath it, whether grafts or biomaterials (synthetic materials). This brings greater comfort to the patient, as it provides a post-operative period with very low morbidity and a rapid recovery.

An implant includes a body including a substrate and a bone interfacing lattice disposed on the substrate. The bone interfacing lattice includes at least two layers of elongate curved structural members. In addition, the at least two layers of elongate curved structural members include a first layer adjacent the substrate and a second layer adjacent the first layer. Also, the first layer has a first deformability and the second layer has a second deformability, wherein the second deformability is greater than the first deformability. Further, one or more of the elongate curved structural members may have a spiraling geometry.

Systems, devices, and methods for providing orthopedic augments having recessed pockets that receive a fixation material. The orthopedic augments include an outer surface that interfaces with a patient's tissue or bone, and an inner surface that interfaces with an implant, the inner surface defining a recessed pocket configured to receive a fixation material, a rim around at least a portion of the recessed pocket, and a port in the rim, wherein the recessed pocket extends along the inner surface in at least a direction laterally from the port.

An implant for use in spinal surgery comprises a resilient element having an inflatable cavity. It is formed of a biologically compatible material and is arranged for placement between end plates of adjacent vertebra. The implant may also include a wound disc replacement element. A method of performing spinal surgery on a patient comprises securely mounting a patient onto a patient support table; imaging a spinal region of the patient; building up a three-dimensional image file of the spinal region of the patient; storing the image file; and utilizing the image file for planning and carrying out computer controlled spinal surgery on the patient utilizing the implant. A computer-controlled surgical implant system comprises a steerable endosurgical implanting assembly operative to install the implant at a desired location in a patient; and a computerized controlled, which operates the steerable endosurgical implanting assembly.

A method of performing a computer-assisted surgical procedure on the spine of a patient comprising the steps of: planning, on a computer, a surgical procedure based on at least one of two- and three-dimensional images of the patient's spine; affixing a robotic assembly over an operative region of the patient; determining, with a computer in communication with the robotic assembly, a desired trajectory of a surgical tool along at least one of an access path and an implant path towards the surgical target site; and placing at least a portion of the surgical tool through the aperture along said desired trajectory along at least one of said access path and said implant path towards the surgical target site.

A dynamic porous coating for an orthopedic implant, wherein the dynamic porous coating is adapted to apply an expansive force against adjacent bone so as to fill gaps between the dynamic porous coating and adjacent bone and to create an interference fit between the orthopedic implant and the adjacent bone.

A guidewire insertion tool includes a sidewall defining a passageway having a first open end and a second open end and a neck therebetween. The passageway tapers from the first and second open ends to the neck. The sidewall has a slit extending longitudinally along the sidewall. A tab is adjacent one of the first or second open ends for removing the tool from a guidewire through the slit.

A woven retention device, lattice device and woven patch device that are configured to receive a fastener in a bone hole can be configured to impede biofilm formation. The devices can be made of woven filaments that outline apertures of varying sizes and shapes and can serve as an interface between a fastener and the bone material. The devices can be configured to allow for optimal bone growth while at the same time minimizing the likelihood that biofilm forms thereon. The devices can be made of materials that facilitate soft tissue fixation, and screw-activated expansion.
