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： A clamp applicable to both temporary and definitive orthopaedic external fixation systems comprising a first coupling element having a pair of opposite jaws defining one or more seats to house a first component of the orthopaedic external fixation system. A second coupling element comprises a pair of opposite jaws defining one or more seats to house a second component of the orthopaedic external fixation system. An interconnection pin passes through and connects the first and second coupling elements along an axis of rotation. A fastening means is arranged to bring the clamp from a slack configuration. The first and second coupling elements are relatively rotatable along the axis of rotation to a locked configuration, and are relatively rotatable with each other. These fastening means include manually operable temporary fastening means to temporarily lock the clamp, and definitive fastening means operable with a fastening tool, to definitively lock the clamp.

摘要： An intramedullary nail for a fractured elongated bone, comprising a cannulated rod having proximal and distal ends; an outside tubular sleeve for coaxially hosting and guiding the rod; and at least a pair of shape memory elements hosted in corresponding seats at the distal end of the rod. Each shape memory element can be retractably housed in its seat in a first configuration, allowing insertion of the nail into the bone, and can project from a sleeve opening in another configuration. Pairs of transversal holes are provided in proximal portions of the rod and the sleeve. The distal pair of shape memory elements lie on an offset plane to the plane of the proximal holes and are kept in their corresponding seats by a distal cover fixed to the rod. This improves the stability of the nail in the medullary canal.
