A revision knee system has a unique polymeric tibial bearing monobloc defining both a superior condylar articular bearing surface and an inferior tibial bearing face. The inferior tibial bearing face bears directly on tibial cut surface so as to withstand compressive loading force applied to the superior condylar articular bearing surface thereof. The bearing component comprises a polymeric keel extending from the inferior bearing face which engages a higher strength metallic stem inferiorly with respect to the inferior bearing face and which may be configured to engage the stem in a structurally resilient manner despite the lower material strength of polymer as compared to metal.

A medical method of affixing an element to a surface of dentine, tooth enamel, bone tissue, or corresponding substitute material. The method includes the steps of: providing an attachment composition, the attachment composition having a mixture of: a thermoplastic component; and a hardenable (for example curable) component. The hardenable component is different from the thermoplastic component. The method further includes the steps of: positioning the attachment composition relative to the surface of dentine, tooth enamel, bone tissue, or corresponding substitute material; and activating the attachment composition to attach to the surface or to attach to the element positioned relative to the surface. The step of activating the attachment composition includes activating the attachment composition by means of mechanical vibration.

Reduced bone fracture fixation devices and methods for using the same are provided. Aspects of the reduced bone fracture fixation devices include a body dimensioned to be positioned in a reduced bone fracture, wherein the body has a wedge shape configuration sufficient to exert a force on bone of the reduced bone fracture and maintain reduction of the reduced bone fracture. The devices, kits and methods of the invention find use in a variety of applications, such as in applications in which it is desired to repair a reduced bone fracture.

A method for promoting spine fusion inside intersomatic cages, comprising placing a fusion cage between two vertebral bodies, and injecting a bone cement paste inside said fusion cage, said bone cement paste containing a powder component comprising -tricalcium phosphate (-TCP) particles having an average size greater than or equal to 9 m, and a liquid component comprising blood.

A modular medical implant allowing the targeted injection of a liquid or pasty material into a bone cavity. This implant is produced with four types of modules provided with a lumen and of variable lengths, including: either a male securing principle, referred to as proximal modules, or a female securing principle, referred to as distal modules, or a male securing principle and a female securing principle, referred to as intermediate modules and perforated intermediate modules, that can be secured in a predetermined order and number in order to position the perforated intermediate modules at suitable levels to allow an injection product to be conveyed to and diffused at the targeted locations, via the perforations, while producing the required length of the implant. The implant is intended, in general, for surgical operations and, in particular, for interventional radiology.

The invention relates to a glenoid (shoulder socket) implant prosthesis, a humeral implant prosthesis, devices for implanting glenoid and humeral implant prostheses, and less invasive methods of their use for the treatment of an injured or damaged shoulder.

A mould adapted to be introduced into a joint of a human patient for resurfacing at least one carrying contacting surface of said joint is provided. The mould is adapted to receive material for resurfacing at least one carrying contacting surface of said joint. The mould is further adapted to be resorbed by the human body or melt after having served its purpose.

Certain embodiments of the invention relate to a surgical procedure resulting in the fusion of transverse processes. The disclosure herein presents novel approaches for accessing transverse processes of the spine, novel methods for the delivery of fusion material for the fusion of said transverse processes, and novel tools to facilitate the procedure. Certain embodiments of the invention include a graft delivery assembly, which has a delivery shaft, delivery sheath, and at least one curved rod. Bony material is position with a graft delivery assembly, in which retraction of the delivery shaft or sheath places the bone fusion material to the fusion site. The graft delivery assembly further includes features to decorticate and prepare the bone surface for fusion.

A device in the form of a kit for mixing and injecting a bone cement is described, in which a mixing unit and a transfer unit are two units distinct from and independent of each other, with no element in common, and are designed to be connected alternately, that is to say successively, to the same end of a hollow cylindrical body or mixing body of a main module, before this main module is connected to an injection unit via its other end.

A method and system for femoral condylar resection arthroplasty of the knee, which preserves the undamaged meniscus, whether by arthroscopy or arthrotomy, and only replaces the damaged area of the femoral condyle. In one embodiment, only the distal femoral condyle is replaced and the posterior femoral condyle remains intact. In another embodiment, both the distal and posterior femoral condyle are replaced. The method and system include placing an intercondylar insert between articular surfaces of a distal femoral condyle and a tibial plateau with the knee in extension. The method and system also includes a box retractor having four right angle blades, two for medial structures and two for lateral structures. The blades are at two depths, shallow and deep. The components of the system are preferably of plastic material. The method and system preserve the meniscus on top of the tibial plateau.
