What are some other mechanical considerations to consider with hybrid frames?

True circular ESF frames are built with three or four threaded rods spanning the length of the involved bone and supporting the ring in several places. Hybrid frames often mimic a Type I-a or Type I-b frame and only support the ring at one or two locations. With 35mm, 45mm or occasionally 50mm rings, a single support may result in a stable frame. When larger rings are used or unstable scenarios are encountered, it is mandatory to use struts or additional sidebars to stabilize the ring in two or more locations.
