An arthrodesis nail and nail adapter system having multiple coupling positions includes a bent arthrodesis nail and a nail adapter. The nail has multiple evenly spaced notches. The nail adapter has multiple evenly spaced protrusions corresponding to the notches. An arthrodesis nail adapter and target arm system having multiple coupling positions includes a nail adapter and a target arm. The nail adapter has a predetermined coupling orientation with a bent arthrodesis nail. The target arm has multiple coupling positions with the nail adapter. The arthrodesis nail and nail adapter system allows rotation of the bent nail for reduction of ankle deformity.

A method of joining adjacent bone includes providing a medical device having a first implant portion, a second implant portion attached to the first implant portion, and a driver assembly having an instrument adapted to form an opening in bone. The driver assembly is integrally connected to and removably attached to the second implant portion at a connection, distal from the first implant portion. The driver assembly further has a wire driver extending therefrom, distal from the first implant portion. The method further includes inserting the wire driver into a wire driver tool; placing the first implant portion against a first bone structure; inserting the first implant portion into the first bone structure; removing the second implant portion from the driver assembly; using the driver assembly to form an opening in a second bone structure, adjacent to the first bone structure; and inserting the second implant portion into the opening.

This disclosure describes exemplary screw and intramedullary devices that are better able to bring bone fragments into close proximity with each other, generate a compressive load, and maintain that compressive load for a prolonged period of time while healing occurs. The devices are made of a shape memory material.

Arthroplasty implant systems and procedures are disclosed herein. In an embodiment, an arthroplasty implant of an arthroplasty system includes a shape memory material connecting member attached to two points of fixation of the arthroplasty implant.

Fixation guide devices and methods for positioning and inserting an intramedullary nail are disclosed. The fixation guide devices include a frame with a first end and a second end, a compression device removably coupled to the first end of the frame, and the intramedullary nail secured to a nail attachment apparatus of the frame. An intramedullary nail including a body with a fastening end, a closed end, and at least two openings is also disclosed. A compression device includes a compression member, a knob, and a bolt secured in the knob and rotatably engaging the compression member is also disclosed. An alignment guide is disclosed and includes a base member, an alignment member, and a fixation guide. A method of inserting an intramedullary nail into two bones for fixation of the two bones is also disclosed.

Instruments, implants, bone plates, systems and methods for correcting bone deformities and fractures in the lower extremity are disclosed. Specifically, targeting instruments, implants, bone plates, systems and methods used for correcting bone deformities and/or fractures in the foot are disclosed.

A stent is disclosed that has an elongated body having a proximal end, a distal end, at least one open spiral channel 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.

The current invention features a rod screw for medical application that can be configured and used to fixate fracture of bones varying in shape and dimension, and treating maladies such as scoliosis, and securing an implanted device, to tissue such as bone. This is achieved by designing a flexible rod screw with a mechanism to lock the configuration in a rigid state. In an embodiment, a bone-fracture fixation device, such as a rod screw, includes a flexible body, a plurality of flexible members, and first and second interfaces. The flexible members are disposed longitudinally within the flexible body, such that the flexible body is rigid when the flexible members are fixed into position. And the first and second interfaces are respectively coupled to the flexible body, each of at least one of the first and second interfaces including a respective at least one hole each configured to receive a respective attachment member configured to engage a bone.

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.

An intramedullary pin includes a main body having a proximal boundary and a distal boundary; a curved extension having a degree of curvature of at least 1°, the curved extension being in direct contact with the distal boundary; a distal cap having a cylindrical portion and a rounded portion, the cylindrical portion being in direct contact with the curved extension; a grip element having at least one contour, the grip element being in direct contact with the proximal boundary; and a proximal cap having a flat surface, the proximal cap being in direct contact with the grip element. Also disclosed is a clamp that includes a handle, two blades, a pivot, and a plurality of grasping elements including a notch, at least one protrusion, and a groove, where one or more grasping elements have a contour that is structurally complementary to the grip element in the intramedullary pin. A method of immobilizing a bone fracture using the intramedullary pin and/or clamp is also disclosed.
