  • Patent number: 9918854
    Abstract: A method of aligning implant components includes placing a first implant component in bone, followed by: coupling a first intermediate member to the first implant component; coupling a first alignment member to the first intermediate member; rotating the members as a unit to place the first intermediate member in an alignment position; removing the first alignment member from the first intermediate member; coupling a second alignment member to a second intermediate member; coupling the second intermediate member to the first intermediate member and rotating the second alignment member and the second intermediate member as a unit relative to the first intermediate member to provide a desired orientation of the second intermediate member. An alignment system for aligning first and second members includes a first alignment member having an offset channel dimensioned to receive the first member, and a second alignment member having a channel dimensioned to receive the second member.

  • Patent number: 9125699
    Abstract: Systems for reducing a fracture in a bone, comprising a bone plate and a polyaxial fastener. In some examples the head of the polyaxial fastener has a deformable portion. As a fastener is inserted into an opening of a bone plate, threads located within the opening deform the deformable portion to secure the fastener in place at a desired angle within the opening. The head of the fastener also includes a bottom portion that bears against a portion of the opening to move the bone plate relative to the underlying tissue. A securing member or other structure may be included at the interface of the head and the deformable portion to secure the deformable portion to the head. At least one flute may be included on the deformable portion that provides a lead-in for the threads within the opening to cut into the deformable portion.

  • Patent number: 8821491
    Abstract: An external fixation component includes a capture member defining opposing grooves on opposite lateral sides of the capture member for capture of an element of an orthopedic fixation system. The capture member includes a base and a head coupled to the base to define a component axis that extends through the base and through the head. The base and the head are coupled for relative lateral translation in opposing directions such that the element can be captured by the capture member in either of the opposing grooves.
