ABSTRACT:
By virtue of its modular construction, this external fixator makes it possible to position the pins (21 to 25) in the bone fragments (11 to 13) taking account of anatomical criteria. The pins are at least indirectly integral with universal joints (36 to 38) with balls (46 to 48) permitting the orientation of the pins relative to connecting bars 503 and 504. The external fixator additionally comprises connecting pieces for articulation between the connecting bars (501 to 507), such as the articulation (7), the telescopic connecting piece (8) and orientable connecting pieces (97 to 99). After the onset of osseous consolidation, some of the connecting bars and their connecting pieces can be removed, it being possible for the bars (501,502) to be withdrawn from the vices (65, 66).
