Disclosed herein are electromagnetic enhanced spinal implants inserted into the disc space via a minimally invasive surgical approach. The spinal implants can include one or more internal coils that generate a magnetic field to enhance bone growth. The device can be powered by an external transmitter. The transmitter will provide a minimum voltage and power output that will allow stimulation of the internal coil.

An intervertebral implant for implantation in an intervertebral space between vertebrae. The implant includes a body extending from an upper surface to a lower surface. The body has a front end, a rear end and a pair of spaced apart first and second side walls extending between the front and rear walls such that an internal chamber is defined within the front and rear ends and the first and second walls. The body defines an outer perimeter and an inner perimeter extending about the internal chamber. At least one of the side walls is defined by an integral porous structure.

A tibial insert includes an articular surface and a bottom surface opposite the articular surface. The bottom surface includes one or more bone-conserving features. In some embodiments, the bottom surface may be curved to match a curvature of the articular surface such that a thickness of the tibial insert is relatively constant. In other embodiments, the bottom surface may be relatively planar but include a protrusion extending from a planar base surface to maintain a minimum thickness of the tibial insert. The described features may be incorporated in a uni-compartmental tibial prosthesis, a bi-compartmental tibial prosthesis, or a total knee prosthesis.

The present invention relates to compressed bone-based products and methods to make the same. The maintained compressed state of the product serves to enhance the product's inherent osteoconductivity.

A method, system and devices for the reconstruction of ribbon shaped ligaments following the anatomical native insertion sites of the ligaments in the corresponding bones is described. The reconstruction of the anterior cruciate ligament of the human knee is depicted. The system includes a device for positioning and creating bone-tunnels, the preparation of grafts and the fixation thereof. The devices intended for bone tunnel creation take into account the ribbon-shaped nature of the ligament and can be adjusted to patient specific anatomy and take into consideration the various typologies of the ligament insertion sites. The method and devices for graft preparation are construed to reflect the anatomy of ligaments under consideration as close as possible to native ligaments by imitating the ribbon-like nature of native ligaments. The presented fixation methods follow this principle and are intended to support the ribbon-like nature of the grafts and are intended to support in-growth of the grafts. Furthermore, accessories supporting preparation of the grafts are presented.

A spinal implant includes a hollow body having a distal end, a proximal end, and a pair of lateral walls extending from the distal end to the proximal end, the lateral walls having a concave-shaped cross-section and having concave, non-threaded interior surfaces for defining an at least partially cylindrical internal space between the lateral walls. The hollow body has upper and lower faces that are inclined relative to one another, whereby a distance between the upper and lower faces decreases from a first lateral side of the hollow body to a second lateral side of the hollow body opposite the first lateral side. The implant includes an anchoring member having bone anchoring projections that is inserted into the hollow body. The anchoring member is rotatable for enabling the anchoring member to be screwed into the internal space of the hollow body.

Intervertebral endoprosthesis discs suitable for surgical implantation between two vertebrae having and methods thereof. The prosthetic disc may have an endoprosthesis body including an anterior region and a posterior region designed to be positioned between a first vertebra and a second vertebra with a first and second movable insert positioned rotatably in anterior cavities and is rotatable to adjust the fasteners.

An intersomatic prosthesis with lateral introduction with a prosthesis body symmetrical along a sagittal plane is provided. The intersomatic prosthesis includes a convex anterior lateral wall along an anterior radius of curvature and a convex posterior lateral wall along a posterior radius of curvature larger than the anterior radius of curvature, a right end wall and a left end wall, and a lower bearing wall and an upper bearing wall open onto an inner space. The lower bearing wall has a central lower portion provided with lower teeth having lower bearing tips defining a lower bearing surface which is planar, and the upper bearing wall has a central upper portion provided with upper teeth having upper bearing tips defining an upper bearing surface which is convex.

Unicondylar tibia implant devices having a bone-facing, distal side that can be detailed with cement fixation features and may include any of or a plurality of grooves, pegs, fins, rails, cavities, and/or coating whereby the geometry of the implant device improves implant-to-cement or cement-to-bone fixation characteristics exceeding that of a traditional flat surface. The implant device may also include a proximal side facing away from the bone-facing, distal side and having a geometry that provides either articulation with (cartilage and meniscal substituting) or receipt of a secondary device coupleable to the implant device on the distal side of the secondary device that features an away-from-bone facing articulating feature. Additionally, the geometry of the implant device in anterior-posterior and medial-lateral directions, among other directions, provides a variety of improvements relative to currently available devices.
