Fig. 2From: Mechanical wear analysis helps understand a mechanism of failure in retrieved magnetically controlled growing rods: a retrieval studyPlain radiographs of two MAGEC rods with intact (a) and damaged (b) internal mechanism. In the first rod (a), the connection of internal mechanism was intact (circle) and the internal driving screw was within the actuator case (box). In the second rod (b), the internal mechanism was disconnected (circle) and the internal driving screw was beyond the actuator case (box)Back to article page
