摘要: A method of producing a bioactive surface on a medical device configured for cementless implantation is disclosed. The method can include treating a titanium metal or titanium alloy medical device, optionally having a titanium metal or titanium alloy porous coating, with a series of steps to obtain the bioactive surface having a nanofibrous network of titanate overlaid with hydroxyapatite particles or film. The steps can include treating the medical device with an acidic solution to obtain an activated surface; oxidizing the activated surface using plasma electrolytic oxidation to obtain an oxide layer having bioactive elements, compounds, or phases; treating the oxide layer with an alkaline solution to obtain the bioactive surface; and treating the bioactive surface with an iodine containing compound to obtain an antibacterial and bioactive surface.

摘要: To provide a bioimplant capable of controlling a rate of an antibacterial agent and an antibiotic to be eluted from the coating film. An evanescent coating film made of a calcium phosphate-based material having crystallinity of 10% to 90% is formed at a predetermined area of the bioimplant and an antibacterial agent or an antibiotic is contained in the coating film to suppress adhesion of bacteria.

摘要: An orthopedic implant having a metal surface and a calcium phosphate layer disposed on at least part of the metal surface is described. The calcium phosphate layer has an average crystallite size of less than about 100 nm in at least one direction and dissolves for more than 2 hours in vitro. The calcium phosphate layer is substantially free of carbonate. The coating, which is formed on a sodium titanate surface, has increased shear strength and tensile strength. The coating is formed by a solution deposited hydroxyapatite process under inert conditions. The pH of the solution varies by less than 0.1 pH unit/hour during coating formation.

摘要: The present disclosure relates to bone graft substitute formulations with a liquid weight to powder weight ratio (L/P) of about 0.35 to about 0.40. The formulations disclosed herein have significantly longer set times than formulations with lower L/P ratios, and yet the cement resulting from the formulations disclosed herein have comparable dissolution rates to those of formulations having a lower L/P. The present disclosure also relates to kits for making the bone graft substitute formulations and methods of treating bone defects with said formulations.

摘要: In the present disclosure, an artificial joint stem includes a base and a coating film located on the base. The base includes a first region, a second region, and a third region located in sequence. The coating film contains a calcium phosphate-based material and an antimicrobial material. The coating film is located across the first region and the second region, and the third region is exposed from the coating film. The surface of the coating film located in the first region has a larger surface roughness than the surface of the base in the third region.

摘要: An implant and/or an implant component is made available, having a main body which, at least on a surface, contains or consists of an electrically conductive material, and having a layer of calcium hydroxide applied to the electrically conductive material of the main body. The implant or the implant component is characterized in that the layer of calcium hydroxide contains calcium phosphate, specifically in a percentage by weight that is less than the percentage by weight of calcium hydroxide in this layer. A method for making available the implant according to the invention or the implant component according to the invention is also proposed. The implant made available and the implant component made available are characterized in that they have a local and temporary antimicrobial action, prevent formation of antibiotic-resistant microorganisms, act on bone substance in a manner that promotes growth, and produce no adverse side effects in the body.

摘要: An adjustable spinal fusion intervertebral implant including upper and lower body portions each having proximal and distal surfaces at proximal and distal ends thereof. The implant can include a proximal wedge member disposed at the proximal ends of the respective ones of the upper and lower body portions, and a distal wedge member disposed at the distal ends of the respective ones of the upper and lower body portions. First and second linkages can connect the upper and lower body portions. Rotation of an actuator shaft can cause the distal and proximal wedge members to be drawn together such that longitudinal movement of the distal wedge member against the distal surfaces and the longitudinal movement of the proximal wedge member against the proximal surfaces causes separation of the upper and lower body portions.
