Abstract:

An assembly tool comprises in an assembled configuration a proximal implant fastener, a distal implant fastener, and a compression member. The assembly tool is operable to hold in the assembled configuration a proximal implant partially engageable with a distal implant during implantation and axial impaction. Axial impaction is exerted through the compression member of the assembly tool. The assembly tool is also operable to securely lock the tapers of proximal and distal implants after impaction by rotating the compression member.

Abstract:

An implant for a hip can include a lateral augment adapted to be coupled to a lateral side of a femoral body implant. The lateral augment can include a body portion having a first surface, a second surface opposite the first surface, and a protrusion extending from the second surface. The protrusion can have a shape adapted to mate with a complimentary shaped recess formed in the lateral side of the femoral body implant. An aperture can be positioned in the body portion and extend through the protrusion. A fastener can be received through the aperture and adapted to be threadably secured to the lateral bore. The fastener can be configured to have a length sufficient to pass through a portion of a greater trochanter for securing the portion of the greater trochanter and the lateral augment to the femoral body implant.

International Classification:

A61B 17/88

US Classification:

606100

Abstract:

A method of implanting a modular implant having a proximal implant and a distal implant into an anatomic site includes sequentially assembling a plurality of components of an assembly tool on to the proximal and distal implants and holding corresponding tapers of the proximal and distal implants separated by a selected separation distance by the assembly tool. The method also includes impacting the proximal and distal implants to an anatomic depth without changing the separation distance by impacting the assembly tool, and actuating the assembly tool to lock the corresponding tapers of the proximal and distal implants without removing the assembly tool.

Assignee:

The Regents of the University of Michigan - Ann Arbor MI

International Classification:

A61B 1732

US Classification:

606 79

Abstract:

A surgical method and apparatus and cannulated scalpel for use therein are provided. In particular, the cannulated scalpel is used during surgical procedures to make an incision through intervening tissue about a guide pin having an end for engaging a target tissue, such as bone. The scalpel includes a hollow, elongated shaft adapted to slide over the guide pin and a head mounted at one end of the shaft. The head has at least one leading cutting edge that is adapted to cut along a plane through the intervening tissue as the shaft slides over the guide pin toward the target tissue engaging end of the guide pin. The scalpel can then be removed from the incision along the plane, preferably with the aid of a trailing guide edge. Following removal of the scalpel, a driving tool, such as a power surgical drill, can be introduced to drive a cannulated fastener along the guide pin and through the incision to embed the fastener in the target tissue and provide fixation of the target tissue.

Abstract:

Methods and apparatuses including apparatuses that can be used in a unicompartmental knee replacement procedure, a bicompartmental knee replacement procedure comprised of two unicompartmental knee replacements, a knee replacement procedure that utilizes a single femoral component and two unicompartmental tibial components, and other types of knee replacement procedures are disclosed. According to one example, an apparatus for guiding a tibial bone cut during knee replacement surgery is disclosed. The apparatus can comprise a mounting portion and a cutting portion. The mounting portion can be configured to couple with an alignment mechanism. The cutting portion can be connected to the mounting portion and can define a capture for a proximal cut. The cutting portion can have an aperture disposed adjacent a first end of the capture.

Abstract:

Therapeutic polymeric materials, therapeutic polymeric materials containing medical implants and methods for making the same, and related materials are described. Methods of making medical implants containing additives antibiotics, therapeutic polymers, and materials used therewith also are described. Methods of spatially controlling additive/antibiotic concentrations, non-homogenous distribution of therapeutic agents in polymeric materials and therapeutic medical implants containing layered constructs of polymeric materials are provided. Therapeutic medical implants containing incorporated therapeutic agents in the polymeric materials, for example, antibiotics into polymeric total joint implants, are useful for delivery of the therapeutic agents into the surrounding mediums.
