ABSTRACT:
The external splint for the treatment of fractures of the long bones of limbs is composed of a tubular body which encloses a cylindrical cavity and has one end prismatically engaged in a seat of a box-like element, which is elongated transversely to the axis of the tubular body. The box-like element is coupled to the tubular body by means of a screw which is rotatably supported in the box-like element and is screwed in a threaded hole defined in the end along the axis of the seat. The screw is cannulated to allow the accommodation of a strain-gauge for monitoring the behavior of the splint. A support for supporting the nail-holder clamps are applied to the box-like element and to the tubular body so that it is possible to adjust them according to a total of three degrees of freedom.
