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.

Abstract: A device of performing osteosynthesis includes an osteosynthesis element, e.g., a bone plate, having an upper face, a lower face and an opening with a central axis linking the upper and lower faces. The opening receives a multi-axial pivotable insert for a longitudinal bone fixing element, such as a bone screw. The insert has a central passage with a longitudinal axis for housing the bone fixing element. The insert may be configured as a helical spring with an external sheath surface and an internal sheath surface that defines the central passage. When placed in the through hole, the insert is rotationally fixed relative to its longitudinal axis, but remains pivotally adjustable within the through hole relative to the osteosynthesis element.
