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 relates to a programmable wrench for automatically adjusting the length of external fixation struts, the programmable wrench comprising: a mechanical connector meant to releasably engage with the external fixation strut thus enabling transmission of at least an adjustment torque from the programmable wrench to the external fixation strut; and an electrical connector meant to releasably connect with the external fixation thus enabling at least a data transmission from the external fixation strut to the programmable wrench. The mechanical connector and the electrical connector may be integrated in a common port and may be jointly engaged and disengaged with the external fixation strut.

摘要： The present disclosure relates to external fixation struts and systems utilizing the external fixation struts. The struts include an elongated body comprising a first and a second hollow tubular shaft and include opposite connectors respectively coupled to an end portion of the first or the second shaft and each including a ball and socket joint. One shaft may have an internal diameter that is slightly larger than the external diameter than the other shaft to host internally the other shaft in a slidably and telescopic manner. A clamp element may provide a fast gripping action stopping the telescopic sliding of one shaft inside the other shaft. Each ball and socket joint connector may be structured to allow an angular movement of the corresponding connector with a spherical angle up to at least 90°.

摘要： An orthopedic spring hinge and associated external fixation systems for the treatment of anatomical joint dysfunctions, and more particularly, to a spring hinge comprising a first base member, a second base member, a flexible first spring having a first longitudinal axis extending from the first base member to the second base member, and a flexible second spring spaced apart from the first spring and having a second longitudinal axis extending from the first base member to the second base member. The spring hinge is configured to have a maximum bending resistance in a first plane extending between the first spring and the second spring and a minimum bending resistance in a second plane orthogonal to the first plane.
