US Patent 10130391 External fixation struts

Dynamization struts and methods of use are provided. A dynamization strut may comprise a sleeve, a shaft, a biasing member, and a bushing. The sleeve may comprise an inner recess with a first and second section. The shaft may comprise an interior section to be disposed within the inner recess of the sleeve. The biasing member may be disposed around the interior section of the shaft, and sized to fit within the first section of the inner recess of the sleeve. The bushing may be secured against a portion of the shaft. Rotation of the bushing may provide for compressive movement of the biasing member relative to the sleeve and shaft. Compression of the biasing member may occur without a corresponding change in a total length of the dynamization strut. Rather, changes in the length of the strut may occur as a result of external compressive forces acting upon it.
