    摘要: A system for fixation of bone, including a bone plate with an opening comprising threads made of a first material and a fastener with a head at least partially comprising a polymeric material that is softer than the first material. In some embodiments, when the fastener is inserted into the first opening, the threads of the first opening form threads in the polymeric material on the head of the fastener and secure the fastener in place at one of a plurality of possible angles within the first opening. The first opening additionally accepts a fastener with a substantially spherical head for compression of a fracture, or a fastener with a threaded head that engages with the threads of the threaded opening. In some embodiments the first opening includes a substantially frustoconical-shaped top portion. In other embodiments there may be a second opening that is either non-threaded or comprises a plurality of protruding fins.

    摘要: A system (1010, 1110) for identifying a landmark is disclosed. The system includes a field generator (1016, 1116) for generating a magnetic field, an orthopaedic implant (1030, 1130) located within the magnetic field, the implant having at least one landmark (1028, 1128), a removable probe (1029, 1129) with a first magnetic sensor (1026, 1126), a landmark identifier (1016, 1116) with a second magnetic sensor (1020, 1120) and a processor (1012, 1112) for comparing sensor data from the first and second sensor and using the set distance to calculate the position of the landmark identifier relative to the at least one landmark. The system allows for blind targeting of one or more landmarks.

    摘要: A medicament containment device (106) is provided containing a medicament (114) and is associated with an implant, such as an orthopaedic implant (102). The medicament containment device (106) can degrade upon exposure to energy, such as energy (112) from an energy source (110). The orthopaedic implant (102), including the medicament containment device is implanted or inserted into an environment (100) such as a patient's body. The energy source (110) can be used outside the patient's body, but in proximity to the orthopaedic implant (102), to apply energy (112) to the medicament containment device (106). Upon exposure to the energy (112), the medicament containment device (106) can degrade and release the medicament (114) into the environment (100). The medicament (114) can kill and/or disrupt bacterial cells (108) or other infectious cells that form in proximity to the orthopaedic implant (102).
