Abstract: In a distraction apparatus for plastic reconstruction of hand, having a proximal support made as a cramp-shaped plate carrying two fixing pins, a distal support carrying distraction pins, and two distraction threaded rods on which the proximal support and the distal support are fitted, according to the invention, the fixing pins are arranged in a plane square with the planes of the cramp-shaped plate, while the distal support is made as a bar having perforations, wherein additional distraction threaded rods are fitted, the distraction pins being held with their distal ends to the proximal ends of the additional distraction threaded rods.

Abstract: In a compression-distraction apparatus for osteosynthesis, including at least two supporting units (1), each incorporating at least two fixing pins (3) fitted in pin holders (2) which are made as a bolt (4) carrying plates (8) having open slots (10) for the pins (3) to fit and a set of spacer shims (9) and are fitted on a threaded rod (6) with a possibility of moving lengthwise its axis, according to the invention, the bolt (4) of the pin holder (2) has an axial hole (5) through which the main threaded rod (6) is free to pass, and the plates (8) and the spacer shims (9) are shaped as washers set on the bolt (4), the open slots (10) for the pins (3) to fit are made on the end surfaces of the plates (8) and pass along the chord of their circumference on the far side of hole (12) in the washer, and the pins (3) are curved and locked in place in the pin holder (2) in a criss-cross manner.

Abstract: A drive of a compression-distraction apparatus, comprising a lead screw whose thread is mated with an opening of a ratchet wheel placed in a housing, a pawl interacting with teeth of the wheel and connected to a load-bearing element manufactured from an alloy possessing plastic memory. The load-bearing element has a rectilinear shape and is essentially a tie-rod whose one end is rigidly secured to the housing while the other end is coupled to a resilient member and the pawl, said load-bearing element being further provided with an electric heater connected to the housing.
