An intramedullary nail implant for positioning in a bone having a head and a shaft defining an intramedullary canal. The implant includes a distal portion having a shaft extending along a central axis and configured for positioning within the intramedullary canal. A proximal portion extends proximally from the distal portion. The proximal portion defines a contact surface which extends at least in part medially of the central axis such that it is configured to extend within a medial portion of the bone head. A method of implanting the nail is also provided.

Implantable devices for fixation of curved bone such as the pelvic ring pubic symphysis and acetabulum, and methods for the use of the devices are disclosed. The implantable devices are convertible between a flexible state and a rigid state, and include an elongate structure having a proximal bone interface, a main body, and a distal bone interface. In a flexible state, the devices may be inserted along, and conform to a curved pathway, and in the rigid state, the devices may support the mechanical loads required to fixate a fracture.

Implant guides, devices, systems and methods for implants to correct bone deformities and fractures in the lower extremity are disclosed. Specifically, implant guides, devices, systems and methods used for implants to correct bone deformities and/or fractures in the foot and ankle are disclosed.

Disclosed is an intramedullary nail comprising a shaft having a length, a constant diameter, an exterior bone contacting surface, a leading (or distal) end and a trailing (or proximal) end, wherein the leading end is progressively tapered and comprises a well or cup, adapted to receive the tip of a standard K-wire, the trailing end comprises a driving fitting adapted for attachment to a driving tool for insertion of the nail into the prepared bone, the trailing end may optionally include an internal thread that can be used to secure the nail to a drill guide which can also function as an insertion handle, and the nail's shaft may also optionally be equipped with threaded and/or unthreaded cross-drilled holes for insertion of unicortical locking screws and bone screws, respectively, once the nail is placed as desired.

A bone fixation device configured to fix one or more bone segments is provided.

Knee arthroplasty instrument systems directly reference and align with the anterior distal femoral cortex and the mechanical axis of the leg. The anterior femoral resection is aligned in the same plane as the anterior distal femoral cortex. The center of the femoral head, the medial/lateral center of the distal femur, the medial/lateral center of the proximal tibia, and the second toe, medial/lateral center of the ankle, or anterior tibial spine are all aligned to the mechanical axis of the leg. Methods of using the instrument systems are disclosed.

A tether for an implantable bone device, the tether including a retention portion for holding the implantable bone device in place, wherein the retention portion comprises a recess configured to receive a protruding proximate end of the device when the device is positioned inside a bone, wherein the recess is open at a first end and closed at a second end; and a fastening portion for affixing the tether to the bone, wherein the fastening portion comprises one or more through fastener openings, wherein each through fastener opening is configured to receive a bone fastener, wherein the fastening portion is adjustable, and wherein the fastening portion is shaped to be less thick that a height of the retention portion.

This disclosure provides an apparatus and method for manufacturing a arthroscopic intra-articular pin aimer is provided. The arthroscopic intra-articular pin aimer is arthroscopic intra-articular pin aimer meant to guide and change direction of arthroscopic, intra-articular pins used to drill within a joint. The arthroscopic intra-articular pin aimer includes a partial loop formed to capture an intra-articular device entered into a joint; an extension neck connected to the partial loop; and a handle connected to the extension neck.

An intramedullary nail implant for positioning in a bone having a head and a shaft defining an intramedullary canal. The implant includes a distal portion having a shaft extending along a central axis and configured for positioning within the intramedullary canal. A proximal portion extends proximally from the distal portion. The proximal portion defines a contact surface which extends at least in part medially of the central axis such that it is configured to extend within a medial portion of the bone head. A method of implanting the nail is also provided.

A method of treating a bone fracture includes taking a first 2D image of an implant and a reference body with an imaging device; creating a 3D orientation of the reference body and the implant based on the 2D image; determining an actual axis of delivery of a bone screw through an opening extending through the implant; determining an optimal axis of delivery of the bone screw through the opening such that the optimal axis of delivery guides the bone screw toward a medically optimal location; and moving the implant such that the optimal axis of delivery and the actual axis of delivery coincide.
