A stent is disclosed that has an elongated body composed of a bioabsorbable polymer having a proximal end, a distal end, two open spiral channels formed on the exterior surface of the body to provide fluid communication between the proximal end and the distal end. The stent also has a central lumen open at the proximal and distal ends of the stent for the passage of a guide wire. A method for using the stent and a kit containing the stent are also disclosed.

A combination of a first assembly for guiding resection of a femur and tibia of a knee joint and a second assembly including femoral and tibial knee components. The combination of the first assembly and the second assembly provides optimal placement and positioning of the femoral and tibial knee components to achieve near-normal knee kinematics and tension. The preparation for and placement of the prosthetic knee components provides medial-pivoting kinematics mimicking that of the natural knee thereby promoting improved outcome for the patient.

A system and method for improving upon an ability of a surgeon to repair traumatic bone injury using new materials, components, and structures. A structure may be used as an implant or a component of an external fixator for a fractured long bone with that structure having anisotropic and viscoelastic properties, such as through additive manufacturing techniques.

Systems and methods are provided for implant design and manufacturing to optimize the bone-implant interface. The implant design and methodology may include accounting for the anatomy of a bone of a subject to address optimize the bone-implant interface considerations for the subject. Implants or components may be asymmetrically designed to better match the associated anatomy as well as optimize the bone-implant interface, such as by quantifying bone density and matching material properties of the implant or coatings of the implant. Information derived from the methodology can be used to guide the design of the implant resulting in an asymmetric design that optimizes the bone-implant interface.

Devices, systems, and methods for bone stabilization, especially proximal humeral stabilization. The stabilization system may include a bone plate having an elongated portion extending along a longitudinal axis and an enlarged head portion extending from the elongated portion. The stabilization system may include an intramedullary nail having an upper portion and a lower portion extending from the upper portion, the upper portion and the lower portion including a plurality of holes. A plurality of fasteners may be configured to extend through one or more of the plurality of through holes in the bone plate and/or one or more of the plurality of holes in the intramedullary nail and into the bone. The plate and nail may each be used alone or in combination together to stabilize a fracture in a long bone, such as a humerus.

A bone fusion implant is provided for treating conditions of Proximal Interphalangeal (PIP), Distal interphalangeal (DIP), and metatarsophalangeal (MTP) foot joints. The bone fusion implant may be a cortical bone allograft sized to fuse the foot joint to be treated. A proximal portion of the implant may be pressed into a hole drilled in a proximal bone portion of the foot joint, and a distal portion of the implant may be pressed into a hole drilled in a distal bone portion of the foot joint. Ramps on the proximal and distal portions facilitate press-fitting the implant into the holes in the bone portions. Side ramps ensure that the bone fusion implant remains substantially aligned with the foot joint while the distal portion is pressed into the hole into the distal bone portion. Grooves on the ramps alleviate pressure and ease inserting the implant into the holes in the bone portions.

A fibular nail for repairing distal fibular fractures is provided that does not require a transfibular-transtibial interlocking screw for stabilization. The nail provides transverse apertures permitting fixation of the proximal and distal portions of a fractured fibula to the nail. The nail has apertures for securing the fibula to the nail on the proximal side of a fracture and on the distal side of a fracture. Optionally, the nail may be connected to the tibia for stabilization.

In one embodiment, the present invention includes an intramedullary osteosynthesis or arthrodesis implant including a central body, a first pair of legs extending from the central body to a pair of leg tips, and a second pair of legs extending from the central body, in a direction opposite the first pair of legs, to a pair of leg tips such that the central body, first pair of legs and second pair of legs are positioned alongside a longitudinal axis.
