Abstract
Apparatus for the fixation of bone fractures and the correction of congenital deformities uses an improved adjustment device that allows selective rotation or lateral translation of one external fixation ring with respect to other external fixation rings. The adjustment device attaches to a pair of first and second tie rod sections and shifts the first tie rod section with respect to the second tie rod section during adjustment. The adjustment device has a lateral slot that defines the path of movement for one of the translating tie rod sections. A travelling block connected to the moving tie rod section tracks the slot during use.
