    摘要: 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.

    摘要: 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.

    摘要: 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.

    摘要: The present disclosure relates to an external fixation apparatus comprising a strut having a longitudinal axis defined therein, the strut comprising a strut housing having a housing adjustment aperture, an adjustment sleeve slidably disposed within the strut housing, and a fastener that releasably couples the strut housing with the adjustment sleeve. An embodiment of the adjustment sleeve comprises a first and a second bore extending from a top towards a bottom surface of the adjustment sleeve, a first sleeve member with a proximal end, a distal end, and an axial bore, and a second sleeve member adjoining the first sleeve member. In an embodiment, the second sleeve member comprises a body and a beveled end that is slidably disposed within the axial bore of the first sleeve member. The adjustment sleeve further comprises a biasing mechanism between the first sleeve member and the second sleeve member.

    摘要: The present disclosure provides an external fixation strut for an external fixation device having a ball joints that can be attached to the outer or inner surface of the ring and locked to increase overall stability of the external fixation device. Some embodiments of the fixation strut include a first ball joint coupled to a first end portion of a strut housing, the strut housing having an axial bore defined therethrough. A second ball joint is coupled to a second end portion of an elongated member. The elongated member is coupled to an adjustment mechanism, which is coupled to an upper end portion of an adjustment sleeve. The adjustment sleeve is slidably disposed in the axial bore of the strut housing, and is used to effect coarse strut length adjustments. Gradual strut adjustments are effected by translating the elongated member.
