ABSTRACT:
A clamping coupling for fixing bone screws, pins or the like incorporates a rotary joint between the bone-screw fixing region of the coupling and a ball-joint connection region of the coupling, whereby an extended range of angular adaptability and fixation are achievable, as compared to the more limited range of angular articulation achieved by the ball-joint action alone.
