<p>Figures (1 and 2) show a bone fixator having clamps (10A, 10B) for bone pins (11) connected by means (12) including a ball-and-socket joint (13, 14) having at least one setscrew (15) in the socket wall (17) to dig into the ball (13) for setting up a fracture, but with the intention of being releasable for re-setting of the clamps at a later stage; also having the advantage of being more convenient for use in high ambient temperatures or in poor lighting conditions that previously disclosed fixators using hardenable resin filler to secure the ball joint. Three setscrews (15) in the socket wall (17) are preferred.</p> |
