[Comparative investigations on the stability of fracture fixations with different fixateurs externes (author's...

Short oblique fractures of the tibiae were stabilized with two-dimensional (frame spanner), three-dimensional and various V-shaped fixateurs externes, applied at the ventral-medial side. The stability of all these different types of fracture fixations was tested with and without an additional lag screw. Under a torsional load the stability of the area of osteotomy was measured. The three-dimensional fixateur externe and the V-shaped fixateur externe yielded the best results. The use of an additional lag screw produced a greater and significant (p less than 0,01) improvement.
