Abstract: A motor-driven orthopaedic frame for the therapeutic exercise of the lower extremity of a patient has a chassis on which a carriage is slidable and which has a calf support portion and a foot support portion which can be pivoted about an axis transverse to the free sliding direction of the carriage on the latter. A threaded spindle serves to drive these supports about the respective axis for extension and flexure of the lower leg.

Abstract: A bed for immobile patients includes a height-adjustable bed frame mounted on a sub-structure provided with at least two spaced apart and connected with one another pivotable sectors driven by a flexible element passing through a plurality of rollers and fixed to extremeties of at least one sector and with a rail having a form of an arcuate of U-shaped depression running along at least one side of each sector and receiving guiding elements rotatably mounted on stands juxtaposed with the sectors.

Abstract: A motion exerciser for the lower leg of a patient engages only the lower leg and has a tray receiving the calf of the lower leg connected by describing elements to a frame which is inclined upwardly away from the patient. A motor-driven carrying element is reciprocatable along the tray and is pivotally connected to the lower leg support at whose opposite end from the tray a footrest is provided which can be moved back and forth on the lower leg support against the force of a pair of springs. A display is provided for the force generated against the footrest.

Abstract: A positioning device for use with an extension and repositioning apparatus for the orientation of an extremity comprises a support cradle for the extremity and a connection element. The support cradle is formed of a lower post fastened to the extension and repositioning apparatus. The support cradle is further formed of a laterally projecting support arm and a raised mounting arm essentially parallel to the post. The connection element is couplable to the support cradle by releasable pin connections to secure a limb. The support cradle and connection element may be formed of sterilizable, X-ray transparent plastic material.

Abstract: The invention relates to an auxiliary table for operations for the extension and repositioning of an extremity in preparation for the nailing of bones or the like. The table has a frame movable on rollers, that has a longitudinal member with a proximal and a distal transverse beam. A mount is fastened on the proximal transverse beam. On the distal transverse beam, two pivotable arms with adjustable extension rods are mounted. In order to make possible free access to the location of the fracture by the operator and the video recording apparatus, the mount (19) is vertically movably supported on a free-standing support column (11) integral with the frame (12, 13, 14). Free-standing posts (17, 18) are fastened on the lateral ends of the distal transverse beam (14) of the frame on which arms (20, 30) are supported.
