<p>A stabilizer for treating broken bones constitutes a dynamic fixator for treatment of fractures in the neighbourhood of various bone joints. The stabilizer is constructed of a proximal assembly consisting of the connector (7) shiftable on rails (1, 2) by adjustment means (18) via spring elements (17). The rails (1, 2) are connected with the stabilizer joint (3) whose axis is coincident with the joint to be spanned. In the connector (7) there are formed openings for bone screws (14, 15, 16), introduced to the bones at right angles or at any other angle required for increased stability. Reposition is enabled by lateral shifting of bone screw (15) in oval opening (11) by means of adjusting screw (32). The distal assembly may be the same as the proximal assembly, or may take various forms depending on the joint to be spanned.</p> |
