Abstract: A fracture fixation system 10, 20, 30, 40, 50, 58, 70 for a fractured bone having at least two bone fragments is disclosed. The fracture fixation system 10, 20, 30, 40, 50, 58, 70 includes an orthopaedic implant 11, 21, 31, 41, 51, 60, 71, an engaging member 12, 22, 32, 43, 45, 52, 62, 72 adapted to gain purchase in at least one bone fragment, and means for applying a force to the engaging member such that the at least two bone fragments are placed in compression and prevented from rotating relative to the orthopaedic implant. The engaging member 12, 22, 32, 43, 45, 52, 62, 72 is disposed relative to the orthopaedic implant 11, 21, 31, 41, 51, 60, 71. The orthopaedic implant 11, 21, 31, 41, 51, 60, 71 may take the form of an intramedullary device, a compression plate, or a deployable material.

Abstract: Systems (10, 110, 1010, 1110) for identifying landmarks (31, 131, 1028, 1128) on orthopedic implants (30, 130, 1024, 1124) are disclosed. The systems (10, 110, 1010, 1110) include a field generator (16, 116, 1016, 1116) for generating a magnetic field and an orthopedic implant (30, 130, 1024, 1124) located within the magnetic field. The implant (30, 130, 1024, 1124) includes at least one landmark (31, 131, 1028, 1128), an optional removable probe (1029, 1129) and a first magnetic sensor (32, 132, 1026, 1126).

Abstract: An instrument for reduction of a bone fracture is disclosed. The instrument includes an orthopaedic surgical implant (112), an implant member (190, 200, 270), and a driving member (180, 210, 260). The implant member (190, 200, 270) has a bone engagement portion (195, 203, 275) and a driven portion (197, 208, 278). The driving member (180, 210, 260) cooperates with the driven portion (197, 208, 278) to move the implant member (190, 200, 270) and reduce the fracture. Also disclosed is a sliding compression orthopaedic implant (300). The implant (300) comprises a first implant member (310), said first implant member (310) having a transverse hole (311); and a second implant member (312) connected to said transverse hole (311), said second implant member (312) having a shank (314), and said shank (314) having a bone engagement portion (316) at a first end portion (318) and a sliding compression member (320) at a second end portion (322).
