Abstract
An orthopedic brace for the reduction of long-bone fractures, which includes telescopic components (7, 8) which are made of an X-ray transparent material and form two transverse plates (9 and 10) at their opposite ends. A locking device (11) is composed of a slide (12) working in conjunction with two chucks (13 and 14) fitted to the periphery of the plates and position-adjusting devices for each flange are made up of three threaded rods (40) angularly equidistant, individually adjustable as to length and mounted in the corresponding plate by means of three ball-and-socket joints.

External holding and reducing brace for bone fractures, of the type comprising an elongated support (6) made up of two telescopic components (7, 8), a device (11) for adjusting and locking those telescopic components, two end flanges (23, 24) fitted to the opposite ends of those components by means of position-adjusting devices (25, 26) and movable pins (1, 2) gripped by the flanges to point in a direction different from that if axis x--x' of the elongated support and designed to be screwed from outside the limb into the fractured bone (4) and on either side of the line of fracture (5), characterized by the fact that:
- the telescopic components (7, 8) are made of an X-ray transparent material and form two transverse plates (9 and 10) at their opposite ends;
- the locking device (11) is composed of a slide (12) working in conjunction with two chucks (13 and 14) adapted to the periphery of the plates;
- the position-adjusting devices, for each flange, are made up of three threaded rods (40), angularly equidistant, individually adjustable in length and mounted by means of three ball-and-socket joints in the corresponding plate.
An external holding and reducing brace for a bone fracture in a limb, comprising:
- an elongated support having first and second telescopic components;
- means for adjusting and locking said first and second telescopic components;
- a first end flange cooperatively connected to said first telescopic component;
- a second end flange cooperatively connected to said second telescopic component;
- means for positioning and adjusting said end flanges relative to said telescopic components, said positioning and adjusting means for each said end flange including a plurality of rods pivotably connected to said telescopic component and means for individually adjusting the locking mechanisms in length to alter the angular relationship of said end flange relative to said telescopic components;
- and
- a plurality of first movable pins and a plurality of second movable pins gripped by said first and second end flanges, respectively, to point in a direction different from that of the longitudinal axis of said elongated support, said movable pins adapted to be screwed from outside the limb into the fractured bone on either side of the bone fracture.
An external holding and reducing brace for a bone fracture in a limb, comprising:
- an elongated support having first and second telescopic components which are made of an X-ray transparent material, said elongate support including first and second transverse plates at opposite ends of said elongate support, said first transverse plate attached to said first telescopic component and said second transverse plate attached to said second telescopic component;
- means for adjusting and locking said first and second telescopic components;
- a first end flange cooperatively connected to said first telescopic component;
- a second end flange cooperatively connected to said second telescopic component;
- means for positioning and adjusting said end flanges relative to said telescopic components, said positioning and adjusting means for each said end flange including three threaded rods pivotably connected to said elongate support by ball-and- socket joints and individually adjustable to alter the angular relationship of said end flange relative to said telescopic components;
- and
- a plurality of first movable pins and a plurality of second movable pins gripped by said first and second end flanges, respectively, to point in a direction different from that of the longitudinal axis of said elongated support, said movable pins adapted to be screwed from outside the limb into the fractured bone on either side of the bone fracture.
