Shoulder arthroplasty systems and configurations for components thereof are described. For example, implant systems for a total should arthroplasty (TSA), hemi shoulder arthroplasty, and reverse should arthroplasty (RSA) are described. In addition, exemplary configurations for baseplates, glenoid components, glenosphere components, humeral components, humeral head components, humerosocket components, connectors, and adaptors, are described.

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.

Devices, systems, and methods for applying a bioactive coating to an exterior surface of an implant are disclosed. In some embodiments, the bioactive coating may be applied to the surfaces of the implant within the operating room at the time of implantation. In one embodiment, the implant may be a temporary spacer used to temporary replace an implant in a patient suffering from an infection. The temporary spacer being, for example, an antibacterial material for fighting the infection. In some embodiments, the method includes providing a mold of the implant, and providing the bioactive coating within the mold. The method may further include inserting the implant into the mold so that the exterior surface of the implant contacts the bioactive coating, and then removing the implant from the mold.

A femoral head arthroplasty system can comprise a femoral prosthesis comprising a mounting plate having a first side and an opposed second side. An adapter can extend from the second side of the mounting plate. An implant body can extend from the first side of the mounting plate. The implant body can extend from the mounting plate by a distance no greater than 90 mm. The femoral head arthroplasty system can further comprise a femoral head replacement having a generally spherical surface and comprising a recess that is shaped to complementarily receive the adapter of the femoral prosthesis.

A prosthesis for a synovial joint arthroplasty within a human body is provided. The prosthesis includes a first prosthetic component, the first prosthetic component including a first surface and the first prosthetic component being formed of a copolymer elastomer compound, the copolymer elastomer compound including a thermoplastic elastomer, a plurality of long glass fibers, the long glass fibers being randomly dispersed throughout the thermoplastic elastomer, a number of the plurality of long glass fibers protruding outward from the first surface of the first prosthetic component and a plurality of beads, the beads being randomly dispersed throughout the thermoplastic elastomer, a number of the plurality of beads protruding outward from the first surface of the first prosthetic component; a second prosthetic component, the second prosthetic component including a second surface, the second surface of the second prosthetic component positioned proximate the first surface of the first prosthetic component to engage the plurality of long glass fibers protruding from the first surface of the first prosthetic component and the plurality of beads protruding from the first surface of the first prosthetic component allowing the second surface of the second prosthetic component to slide relative to the first surface of first prosthetic component while contacting the plurality of long glass fibers protruding outward from the first surface of the first prosthetic component and the plurality of beads protruding outward from the first surface of the first prosthetic component, a gap, the gap created by the voids between the second surface of the second prosthetic component, the first surface of the first prosthetic component and the plurality of long glass fibers that protrude outward from the first surface of the first prosthetic component and between the second surface of the second prosthetic component, the first surface of the first prosthetic component and the plurality of beads that protrude outward from the first surface of the first prosthetic component, the gap further disposed between the first surface of the first prosthetic component and the second surface of the second prosthetic component to allow the passage of fluid between the first surface of the first prosthetic component and the second surface of the second prosthetic component, a first trough, the first trough formed as the plurality of long glass fibers protruding outward from the first surface are forced into the thermoplastic elastomer as the prosthesis is loaded, the first trough positioned proximate the plurality of long glass fibers and extending a perimeter of the plurality of long glass fib

The present disclosure in one aspect provides a surgical implant comprising an upper bone contacting surface comprising a plurality of irregularly shaped pores having an average pore size, where the pores are formed by a plurality of struts, a lower bone contacting surface comprising a plurality of irregularly shaped pores having an average pore size, wherein the pores are formed by a plurality of struts; and a central body comprising a plurality of irregularly shaped pores having an average pore size, wherein the pores are formed by a plurality of struts, wherein the average pore size on the upper and lower bone contacting surfaces is different than the average pore size on the central body.

An implant (1) for modifying the tissue deformation during bone healing between two bone fragments (5; 6), with a first end piece (2) that can be fastened to a first bone fragment (5) with a longitudinal axis L1, and a second end piece (3) that can be fastened to a second bone fragment (6) with a longitudinal axis L2, wherein the first and second end pieces (2; 3) are loosely meshed with one another by means of n1 parallel-connected tissue activators (4a; 4b) in each case to allow relative movement and the tissue activators (4a; 4b) are arranged to be perpendicular to the longitudinal axes L1 and L2 and preferably orthogonal thereto.
