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.

摘要： An external fixation connection rod that allows for rapid and gradual length adjustment. In some embodiments, the fixation connection rod includes an inner sleeve received within a telescopic rod to allow for rapid adjustment of an overall length of the fixation connection rod. In some embodiments, the fixation connection rod includes an adjustment mechanism to allow for gradual adjustment of the overall length of the fixation connection rod by lengthening or shortening a threaded elongated member within the inner sleeve, and the adjustment mechanism includes a first rotation member, a second rotation member, and a spring. Distal translation of the first rotation member relative to the second rotation member allows the adjustment mechanism to move from a first, locked position to a second, unlocked position, allowing the first rotation member and the second rotation member to rotate about the inner sleeve and the threaded elongated member during gradual adjustment.

摘要： A wire tensioner tip for use with a wire fixation bolt. First and second wires may be anchored to and tensioned across an external fixator frame with first and second wire tensioners. The first and second wires may be anchored at first anchor locations with first and second wire fixation bolts. First and second wire tensioner tips may engage with third and fourth wire fixation bolts, thereby preventing the third and fourth wire fixation bolts from rotating. The first and second wires may be tensioned to a desired tension with the first and second wire tensioners at the same time to prevent over-tensioning or under-tensioning. The first and second wires may be anchored at second anchor locations with third and fourth wire fixation bolts. By engaging the wire fixator bolts with the wire tensioning tips, fewer tools are required and one medical professional can tension two wires at once.
