Abstract

This external fixator for the correction and reduction of bone fragments comprises a bar (1) fastened to a biocompression system (5), on which bar and system are disposed the supports (2, 3) for fastening the pins inserted into the bones, the components of which supports are movable in accordance with the arrows A, B, C and D. The member (6) permits the longitudinal displacement of the clip (2) in the direction of the arrow E, while the biocompression system (5) makes a reciprocating movement in accordance with the arrow F. A damping member (90, 290) cooperates with means for regulating the force applied which are disposed outside the bar. Graduated markings (99, 283) indicate the value of the force applied.
