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.

- an elongated body comprising a first and a second hollow tubular shaft;
- 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 having 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;
- said first and second shafts of the strut being realized by a synthetic radiolucent plastic material;
- a clamp element provided in proximity of overlapping ends of the first and second shaft for providing a fast gripping action stopping the telescopic sliding of one shaft inside the other shaft;
- a manually operated fixation element acting on the clamp element for exerting said fast gripping action
- a sleeve provided around the central portion of the strut where the first and second shaft overlap;
- a clamp band around said sleeve and including opposite and facing gripping portions, said gripping portions being connected by a threaded connector.

摘要： The present disclosure relates to an improved orthopaedic external fixation system with removable rails or skates and comprising: at least a distal foot fixation element; at least a pair of rails or skates removably connected to the foot fixation element; at least a load sensor associated to at least one of the rails or skates; an electronic apparatus coupled to the load sensor and receiving an electric signal from the load sensor; an electronic controller coupled to the apparatus and issuing at least a flag signal upon detection of a threshold pressure force on said at least one of said rails or skates. This electronic controller may be mounted on the orthopaedic system or may be a structurally independent host device including a controller that is in signal communication with the load sensors.
