An osteosynthesis implant includes at least one coupling in the form of a swivel joint. Each swivel joint includes at least one planar or annular swivel element and two connecting arms that define a pivot axis. The coupling permits rotation about each pivot axis. The implant and coupling may be formed of unitary construction, or a separate coupling may be connectable to the implant. The coupling may receive a bone fastener such as a bone screw, or may be used in applications that require the coupling to directly support portions of the body such as spinal features.
