The present disclosure includes fixation devices, such as an orthopedic screw or implant, that comprises one or more porous elements or fenestrations to aid in osteo-integration of the fixation device. The fixation device may be additively manufactured using biocompatible materials such that the solid and porous aspects of the screw are fused together into a single construct. In yet another aspect, the fixation device comprises at least a portion or section incorporating a porous structure, which enables bony ingrowth through the porous section/portion of the screw, and thereby facilitates biocompatibility and improve mechanical characteristics. Methods for using the fixation device are also described herein.

An intervertebral implant for being implanted between adjacent vertebrae is provided. The implant includes a generally elongate implant body having a length extending between opposite longitudinal ends thereof, a superior face and an inferior face. The superior face and inferior face include cortical teeth adjacent to the implant body longitudinal ends. Additionally, the superior and inferior faces include longitudinally central teeth intermediate the cortical teeth and have bone engaging ends. The central teeth have a sharper configuration than that of the cortical teeth bone engaging ends for biting into the softer central bone material of the vertebrae. The cortical teeth are arranged in a first density per unit area and the central teeth are arranged in a second density per unit area that is less than the first density.

A system and method for further improving upon an ability of a surgeon to reduce or eliminate impaction forces when installing or assembling a prosthesis. An implant includes a surface treatment for aiding operations with the implant. For example, some surface treatments provide an asymmetry in installation versus removal to bias the associated implant deeper into an installation site.

A bioactive filamentary structure includes a sheath coated with a mixture of synthetic bone graft particles and a polymer solution forming a scaffold structure. In forming such a structure, synthetic bone graft particles and a polymer solution are applied around a filamentary structure. A polymer is precipitated from the polymer solution such that the synthetic bone graft particles and the polymer coat the filamentary structure and the polymer is adhered to the synthetic bone graft particles to retain the graft particles.

An orthopaedic implant includes an implant body having a first surface, a second surface opposite the first surface, and a cavity formed therein that extends through the first surface and the second surface. The implant body has a third surface with at least one first opening formed therethrough to the cavity. The at least one first opening includes an outer portion having an outer diameter and an inner portion having an inner diameter. The implant includes a load bearing member including a porous material held within the cavity. The outer portion of the at least one first opening is configured to couple to a tool for receiving, from the tool, a material agent, and the inner portion of the at least one first opening is configured to couple to a plug for preventing the material agent from exiting the porous material via the at least one first opening.

A two-part joint replacement device for replacing damaged soft joint tissue, such as a meniscus or cartilage tissue. In one form, the device may include a free floating soft joint tissue replacement component comprising a first tissue-interface surface shaped to engage a first anatomical (bone and/or cartilage) structure of a joint having damaged soft tissue. The device may also include a free floating rigid base component comprising a second tissue-interface surface shaped to engage a second anatomical (bone and/or cartilage) structure of the joint. The free floating soft joint tissue replacement component may be shaped to slidably interface with the rigid base component. In another form, the free floating soft joint tissue replacement component and the rigid base component are fixed together.

Core for a spacer, including a main body that comprises a plurality of through openings, adapted to be secured in a corresponding residual bone bed of a previous implant; the main body being adapted to be covered with a layer (S) of a coating material or a material including acrylic bone cement added or that can be added with one or a plurality of pharmaceutical products or active and/or therapeutic substances.

A biological tissue rootage face (30) capable of closely bonding to a biological tissue (H, S) is composed of a biocompatible material and has numerous fingertip-shaped microvilli (41). The microvilli (41) have tip diameters in the order of nanometers. An implant (1) has the biological tissue rootage face (30) on a surface (11, 24) configured to root into a biological tissue (H, S). In a method for forming the biological tissue rootage face (30), a surface of a biocompatible material is subjected to laser nonthermal processing carried out by emitting a laser beam in air, to form numerous fingertip-shaped microvilli (41). The laser beam is a laser beam of an ultrashort pulse laser.

Arcuate fixation members with varying configurations and/or features are provided, along with additional components for use therewith in provided fixation systems and intervertebral implant systems. The arcuate fixation members may be of varying lengths, cross sectional geometries, and/or cross sectional areas, and may be configured with various features such as heads configured to accept other fixation system components, tabs to allow arcuate fixation member-in-arcuate fixation member or fixation anchor-in-arcuate fixation member configurations. Applications of fixation systems and intervertebral implants systems utilizing arcuate fixation members are particularly suitable when a linear line-of-approach for delivering fixation members is undesirable.

Provided herein are meniscus implant compositions, as well as method for making and using the same. The subject meniscus implants find use in repairing and/or replacing damaged or diseased meniscal tissue in a mammalian subject.
