EXTERNAL FIXATION APPARATUS FOR INTRA-OPERATIONAL REPOSITION AND STABILIZATION OF POSITION OF POST-TRAUMATIC BONE FRACTURES

摘要

FIELD: medicine; orthopedics; traumatic surgery.;SUBSTANCE: apparatus has support rings and connecting rods. Connecting rods are made to be threaded or telescopic. Adjusting nuts are screwed up onto connecting rods. Support rings are made dismountable; they have openings for connecting rods for shifting support rings along connecting rods up and down. Apparatus also has 4 wedge-shaped bushing for any connecting rod. Wedge-shaped are made in five sizes to have slant of one plane in relation other for 3, 5, 7, 10 and 13°. Openings for connecting rods are made with diameter being 30-40% bigger than diameter of connecting rods. Wedge-shaped bushings and adjusting nuts are made of hexahedral bars. Wedge-shaped bushings are provided with recesses in walls at higher sides from up to down for width being equal to value of diameter of connecting rods to put wedge-shaped bushings aside connecting rods. There is no need for additional arm pieces, cantilever adaptors, nuts and bolts.;EFFECT: ability of side shifts of rings one relatively others.
