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 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.

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： A connecting rod for an external fixation device may include a telescopic housing having an axial bore, an inner sleeve slidably disposed within the axial bore of the telescopic housing, a fastener operable to releasably couple the inner sleeve and the telescopic housing, an elongated member coupled to the inner sleeve, and two joints. One joint may be coupled to a proximal end of the telescopic housing, and include a rotatable member and a connecting member coupled to the rotatable member, such that the connecting member is operable to receive a connecting element from an external fixation ring. The other joint may be coupled to a distal end of the elongated member, and include a rotatable member and a connecting member coupled to the rotatable member. Each joint may also include a rotatable member housing with one or more sidewall grooves that limit rotation of the respective rotatable members.
