摘要： An implant insertion assembly including an insertion handle extending from a proximal end to a distal end, the distal end including a recessed portion, an outer wall of the recessed portion having a first shape about a perimeter thereof and including an engagement mechanism. The implant insertion assembly also includes an implant extending from a distal end to a proximal end including an opening configured to receive the recessed portion of the insertion handle, the opening having a second shape configured to mechanically interlock with the outer wall of the recessed portion when the recessed portion is inserted therein to transmit torque from the insertion handle to the implant, the proximal end including a receiving structure in a wall thereof, the receiving structure being positioned and oriented to receive the engagement mechanism to removably lock the insertion handle to the implant in the axial direction.

摘要： Intramedullary fixation assemblies (4, 8) and intramedullary fixation devices (1, 24) can be used in orthopaedic surgery for the fixation of bone fractures. Also disclosed is an insertion device (30) for inserting an intramedullary fixation device, and a method of fixing a bone fracture. The fixation devices are preferably for addressing fractures of the distal radius, and are preferably styloid nails. The styloid nails preferably have a head portion that can accept up to three bone screws; one of the bone screws is designed to extend across a fracture line between a proximal and a distal bone fragment while the other bone screws are designed to be retained in the distal bone fragment.

摘要： In one embodiment, an intramedullary nail has a body that includes proximal and distal ends and an inner surface that defines at least one locking hole that extends into an outer surface of the body so as to receive a bone anchor to lock the nail in a medullary canal of a bone. The body has a first biocompatible material that defines at least a portion of the outer surface. The nail has a second material that is different from, and at least partially encapsulated in, the first material. The second material can produce at least one of an electrical current and a magnetic field, and is supported by the nail body such that a position of the at least one bone-anchor locking hole can be detected based on the at least one of the electrical current and the magnetic field.
