Abstract: A dynamization device includes a first module and a second module. The first and second modules are each rigidly affixed to and mated together by one or more deformable rings. Each of the first and second modules includes an inner column positioned within the one or more deformable rings. The mated first and second modules form a first displacement gap between the inner column of the first module and the inner column of the second module. The first displacement gap extends along the longitudinal axis between adjacent deformable rings of the one or more deformable rings.

Abstract: An external fixation strut includes an elongated body including first and second tubular shafts. Opposite connectors are respectively coupled to one of the shafts and include a ball and socket joint. One shaft has an internal diameter slightly larger than the external diameter of the other to host the other shaft in a slidably and telescopic manner. The shafts of the strut are a synthetic radiolucent plastic material. A clamp element is in proximity of overlapping ends of the shafts for fast gripping action stopping the sliding of one shaft inside the other. A fixation element is manually operated and acts on the clamp element. A sleeve is provided around the central portion of the strut where the shafts overlap. The clamp element is a clamp band around the sleeve and includes opposite and facing gripping portions. The gripping portions are connected by a threaded connector of the fixation element.

Abstract: Dynamization tabs and methods of use are provided. Dynamization tabs may be used with an external fixation ring or other fixator device as part of a therapeutic treatment of bone fractures or malformations. The device forms a connection between one or more fixation struts and an external fixation ring so as to introduce controllable amounts of movement or dynamization to the arrangement of the struts and the fixator. By introducing controlled amounts of dynamization, therapeutic benefits can be derived in the enhanced, accelerated bone formation, mineralization and remodeling of the underlying bone. Dynamization tabs may comprise a strut connector, a mechanical biasing or dynamizing device, and a ring connector. Many different forms for introducing controlled amounts of dynamization are disclosed.

Abstract: Dynamization devices and methods of use are provided. A dynamization device may comprise first and second modules that are mated together in a substantially cylindrical shape. The outer surface of the first and second modules are connected to deformable rings that may be deformed when a longitudinal force is applied to the first and second modules. The deformation of the rings creates a longitudinal mechanical bias in the device to return it to its original shape. The strength, spring coefficient, and size of the dynamization device can be adjusted depending upon the particular needs of the application.
