Systems for treating and/or preventing fractures include at least one needle sized and configured to be placed into target bone and at least one implantable pin configured to be releasably held in a first needle of the at least one needle. The systems also include at least one delivery device of injectable material configured to couple to the first needle while the first implantable pin is held in the first needle whereby the at least one delivery device and a respective needle cooperate to serially provide an external column of the injectable material about the at least one implantable pin.

A system and method for improving installation of a prosthesis, particularly an acetabular cup. The system and method may include implementation of a constant velocity relative motion between a prosthesis and an installation site. For example, an installation system may be fixed relative to the installation site, with the prosthesis fixed into an initial position. The prosthesis is moved at constant speed (i.e., with minimal if any acceleration or applied impulses) relative to the installation site. That is, one or both of the prosthesis or the installation site may be in motion. Resistive forces to installation of a prosthesis may thus be reduced by maintaining the prosthesis constantly in motion relative to the installation site. Securing a processing/implanting tool directly to the installation site may offer advantages.

Proposed is a modular augment, and, more specifically, a modular augment in which an additional unit is separably coupled to a center unit so as to selectively couple the additional unit to the center unit according to the degree of a patient's bone loss so that the degree of bone reinforcement can be easily adjusted, and thus a manufacturer is capable of covering various types of patients even though the types of units are minimized, thereby reducing manufacturing costs, the number of products to be prepared for surgery by a user such as a hospital is remarkably reduced, thereby preventing the unnecessary costs and facilitating inventory management, and a patient can receive an optimal augment that is appropriate for the patient' condition.

A membrane having at least one strip of a shape memory material and the at least one strip is sandwiched between a first layer and a second layer. A method for guiding bone regeneration which excludes the use of a tenting screw is also disclosed. The membrane may be useful for gradual displacing of the soft tissue covering bones. The gap developing between the bone and the displaced soft tissue may be filled with regenerated bone. The membrane allows the regenerated bone to form while the soft tissue heals. The membrane and method may be useful in dentistry for treating vertical bone defects. The membrane and method may also be useful for regenerating soft tissue between the bone and the displaced soft tissue.

Devices and methods for in situ drawing, filtering and seeding cells from the marrow of surrounding bone into a fusion cage without any of the challenges mentioned above. Various implants and devices with aspiration ports that enable in-situ harvesting and mixing of stem cells. These devices may include spinal fusion cages, long bone spacers, lateral grafts and joint replacement devices. Each device utilizes at least one aspiration port for harvesting of stem cell-containing marrow via aspiration from adjacent bony elements.

An intermediate body is for a bone implant for replacement of an osseous area. The intermediate body has a base body and a seat which extends axially in the base body and is surrounded by a wall of the base body. The intermediate body is designed to receive and surround an end portion of an intramedullary implant part. A clamp device is assigned to the seat. A clamp component is arranged on the wall of the base body surrounding the seat. In order to clamp, the end portion is inserted beforehand into the seat relative to the wall of the base body. The wall then surrounds the seat and the inserted end portion is movable towards the seat and in the process clamps the end portion in the seat. An implant arrangement is provided with the intermediate body.
