A femoral orthopaedic prosthesis includes a metallic core extending from a proximal end to a distal tip. The metallic core includes a neck that is positioned at the proximal end and is configured to receive a prosthetic femoral ball. An elongated stem extends distally from the neck to the distal tip. The stem includes a proximal section extending distally from the neck, and a distal section that extends proximally from the distal tip. The elongated stem also includes a pair of spaced-apart beams that connect the proximal section to the distal section. An aperture is defined in the stem between the pair of spaced apart beams.

A method of manufacturing a femoral stem for a hip implant includes forming a femoral neck extending from a proximal end of the femoral stem towards a distal end of the femoral stem, forming an upper section connected to and extending from the femoral neck towards the distal end of the femoral stem, and forming a lower section connected to and extending from the upper section to the distal end of the femoral stem. Further, a method for designing a femoral stem for a hip implant includes generating a customized femoral stem model to match an information of a patient, generating at least one proximal-distal solid rib in the upper section, calculating density and stress distributions for an open lattice and for a closed lattice, and selecting a unit cell type and a pore size for the open lattice and the closed lattice to match a density and/or a stiffness of the patient's femur.

An orthopedic system for delivery of a therapeutic agent to a bone includes an elongate stem adapted to be inserted into an intramedullary canal, an inlet configured to receive the therapeutic agent, and one or more outlets configured to deliver the therapeutic agent to the bone. The elongate stem may comprise one or more protrusions to engage the bone, and one or more channels extending longitudinally therein, fluidly coupled to the inlet. The therapeutic agent flows from the inlet through the one or more channels and exits into the intramedullary canal through the one or more outlets. The system may be configured to allow one or more dimensions of the system to be adjusted to accommodate the anatomy of a patient.

Systems, methods, and apparatuses are provided for delivering reduced pressure to a subcutaneous tissue site, such as a bone tissue site. In one instance, a manifold for providing reduced pressure to a subcutaneous tissue includes a longitudinal manifold body formed with at least one purging lumen and a reduced-pressure lumen. The manifold further includes a plurality of manifolding surface features or slits formed on the second, tissue-facing side of the longitudinal manifold body and a plurality of apertures formed in the longitudinal manifold body on the second, tissue-facing side. The plurality of apertures fluidly couple the reduced-pressure lumen and the manifolding surface features or slits. The manifold further includes an end cap fluidly coupling the reduced-pressure lumen and the at least one purging lumen. Other systems, apparatuses, and methods are presented.

A reduced pressure delivery system for applying reduced pressure tissue treatment to a tissue site is provided. The system includes a manifold delivery tube and a balloon having an inner space. The balloon is capable of assuming collapsed and expanded positions. The system further includes a manifold having a plurality of flow channels. The manifold is disposed within the inner space of the balloon. A sharp tip is configured to be delivered within the manifold delivery tube to puncture the balloon.

Embodiments of an implant assembly for hip replacement surgery is disclosed. In one embodiment, the implant assembly includes a femoral component comprising a stem member configured to extend into a femur of a patient and a locking member configured to extend through the femoral component to affix the stem member to the femur.

The improved endoprosthetic device surface treatment encourages soft tissue attachment thereto. A porous mesh surface treatment creates on an outer surface of the endoprosthetic device a three-dimensional surface structure similar to cancellous bone. Suture attachment features are provided at various locations around the treated surface structure to initially affix a vascularized soft tissue to the treated surface. As the patient heals the soft tissue grows and infiltrates the porous mesh surface to achieve an attachment strength substantially equal to the surrounding tissue.

An artificial hip joint stem is used to replace the damaged femoral head or acetabulum and includes a stem body having a head fixing part, which fixes a head, and an operating space horizontally opened at the upper side thereof. A head insertion hole connects to the operating space. A screw part is inserted into the head insertion hole. An operation converting part is inserted into the operating space to vertically move by the screw part when the operation converting part is connected to the screw part. A fixing bracket is inserted into the operating space such that the screw part is fixed to rotate without changing the depth thereof. A variable operating part is inserted into a supporting surface of the stem body to adjust a horizontal width by means of the operation converting part. A movable pin fixes the variable operating part to the operation converting part.

A femoral orthopaedic prosthesis includes a metallic core extending from a proximal end to a distal tip. The metallic core includes a neck that is positioned at the proximal end and is configured to receive a prosthetic femoral ball. An elongated stem extends distally from the neck to the distal tip. The stem includes a proximal section extending distally from the neck, and a distal section that extends proximally from the distal tip. The elongated stem also includes a pair of spaced-apart beams that connect the proximal section to the distal section. An aperture is defined in the stem between the pair of spaced apart beams.
