An implant having a unitary body includes an intramedullary portion and an extramedullary portion. The intramedullary portion is sized and structured to be received within an intramedullary canal of a first bone and defines a longitudinal axis. The extramedullary portion includes a surface defining an axis that is disposed at an angle with respect to the longitudinal axis. An aperture defined along the extramedullary portion is sized and configured to receive a fastener therein for coupling the extramedullary portion of the implant to a second bone.

A medical implant system is described for inhibiting infection associated with a joint prosthesis implant. An inventive system includes an implant body made of a biocompatible material which has a metal component disposed on an external surface of the implant body. A current is allowed to flow to the metal component, stimulating release of metal ions toxic to microbes, such as bacteria, protozoa, fungi, and viruses. One detailed system is completely surgically implantable in the patient such that no part of the system is external to the patient while the system is in use. In addition, externally controlled devices are provided which allow for modulation of implanted components.

A biodegradable in vivo supporting device is disclosed. In one embodiment, a coated stent device includes a biodegradable metal alloy scaffold made from a magnesium alloy, iron alloy, zinc alloy, or combination thereof, and the metal scaffold comprises a plurality of metal struts. The metal struts are at least partially covered with a biodegradable polymer coating. A method for making and a method for using a biodegradable in vivo supporting device are also disclosed.

Provided are an orthopedic repair scaffold, a preparation method thereof and use thereof. The orthopedic repair scaffold is a three-dimensional porous scaffold. A material of the orthopedic repair scaffold comprises the following components in mass percentage: 80%-95% of a biodegradable polymer and 5%-20% of a biodegradable nanoparticle, where the biodegradable nanoparticle is a nanoparticle of manganese compound. The preparation method of the orthopedic repair scaffold comprises: preparing a homogeneous solution comprising a biodegradable polymer and a biodegradable nanoparticle according to the mass percentage; preparing the homogeneous solution through a curing molding process into a molded three-dimensional porous scaffold; and freeze-drying the molded three-dimensional porous scaffold to obtain the orthopedic repair scaffold. The orthopedic repair scaffold can better promote healing of a bone injury and has an excellent mechanical performance and a good medical imaging function.
