摘要： A method of making a landmark identifier by forming elements at locations in a mounting structure that possesses a first dimension stable autoclavable material. The method secures electromagnetic induction coils at orientations in the elements; forms a hole through the mounting structure; and secures a coupling member to the mounting structure. The coupling member has a through hole that is aligned with the hole formed through the mounting structure when the coupling member is secured to the mounting structure. In addition the coupling member comprising a second dimension stable autoclavable material; covering the mounting structure and the electromagnetic induction coils.

摘要： A controlled removable fracture-reducing assembly (10) for reducing a bone fracture. According to one embodiment of the present invention, a controlled removable fracture reducing assembly (10) includes an implant (12), a reducer (14), a buttress (16), and a locking device (18) that engage a proximal bone fragment (2) and a distal bone fragment (4). The implant (12) is secured to the distal bone fragment (4) by the locking device (18). The buttress (16) engages the implant (12) through an opening (30). The reducer (14) contains a compressing screw (24) that applies a force (60) on the buttress (16), reducing the fracture. According to another embodiment of the invention, the reducer (114) contains a cam mechanism (124) which applies a force (186) on the buttress (116), which does not engage the implant (112), that pushes the proximal bone fragment (102) to reduce the fracture. According to another embodiment of the invention, the reducer (214) is a jacking mechanism that pushes the proximal bone fragment (202) while pulling the implant (212) and distal fragment (204) to reduce the fracture.

摘要： A multi-layer, fiber-reinforced composite orthopaedic fixation device having a design selected based on a desired characteristic of the orthopaedic fixation device. The design may be selected according to a model of the device, the model defining design constraints, and the design may comprise a pattern of the fiber angle for each layer. The selection of a design may be analyzed using finite element analysis to determine whether the design will comprise the desired characteristic.

摘要： Systems, devices and methods are disclosed for limiting compression of a fracture imposed by a lag screw of a fixation system that includes a fixation device, a lag screw and a compression screw. The disclosed devices, systems and methods prevent over-compression of a fracture by a lag screw caused by over rotation of the compression screw. Specifically, implementations of a lag screw driver and a compression screw driver are provided whereby an engagement between the lag screw driver and compression screw driver prevents any further lateral movement of the lag screw, thereby providing a complete stop to further advancement of the lag screw and any additional compression.

摘要： Treating fractures using one or both of an implant, such as an intramedullary nail, and a fastening assembly, such as a lag screw and compression screw assembly. The implant in some embodiments has a proximal section with a transverse aperture having a non-circular cross-section that may be shaped to selectively constrain the fastening assembly within the transverse aperture. Two or more components of the fastening assembly may be received to slide, in a controlled way, in the transverse aperture of the implant, and to cooperate to resist a force moment applied thereto. Without the presence of one of the components, such as the lag screw, another component, such as the compression screw may not resist a force moment applied thereto. In some implementations, an engaging member and a compression device of the fastening assembly are configured so that the compression device interacts with a portion of the implant and a portion of the engaging member to enable controlled movement between first and second bone fragments. This configuration is useful for, among other things, compressing a fracture.

摘要： 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 ).
