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 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.

A bone fracture internal fixator for repairing a bone fracture of a femoral neck that allows load to be applied to the associated bone parts evenly, and increases the connecting strength between the femoral head and femoral shaft while minimizing the risk of the femoral head being torn apart by the inner connecting member by increasing the diameter of the inner fixing member. The central axial line of the femoral head is offset from the central axial line of the intramedullary nail placed in the medullary cavity of the femoral shaft. In order to bring the inner fixing member such as a lag screw configured to be inserted through the femoral neck close to the central axial line of the femoral neck, the central axial line of the through hole for receiving the inner fixing member is offset from the central axial line of the intramedullary nail.

In one embodiment, an intramedullary nail has a nail body that has a proximal end and a distal end that are offset from one another such that the body is elongate from the proximal end to the distal end. The body has an outer surface, and an inner surface. The inner surface defines a cannulation that extends into the proximal end towards the distal end. The body defines a proximal bone-anchor hole that extends into the outer surface and entirely through the nail, and a distal bone-anchor hole that extends into the outer surface and entirely through the intramedullary nail at a location between the proximal bone-anchor hole and the distal end. The nail also defines an access hole extends into the outer surface between the leading portion and the trailing portion. The access hole terminates at the cannulation and is in communication with the cannulation.

A compressive intramedullary rod includes first and second concentric shafts configured to engage with each other in a telescopic manner along a longitudinal axis, through a screw mechanism integrated in the first concentric shaft. The screw mechanism includes a bolt in an upper portion for mounting onto the first concentric shaft, and an externally threaded rod in a lower portion for engaging with an internally threaded first channel of the second concentric shaft. The second concentric shaft includes a second channel extending along corresponding length, and the externally threaded rod portion includes a third channel extending along corresponding length. Further, the second channel fully aligns with the third channel, when first and second concentric shafts engage in a telescopic manner upon rotation of the screw mechanism. The first and second concentric shafts include first and second set of guide holes for coupling to proximal and distal fragments of bone.

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.

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.

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.

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.

Disclosed is a medical device having a first implant portion having a proximal end, a second implant portion connected to the first implant portion, the second implant portion having a distal end, and a driver assembly removably connected to the distal end, the driver assembly comprising a drill connected to the distal end at a connection.
