ABSTRACT:
An external fixator for osteosynthesis features application to the fixation of fractures of small bones such as those of the hand or foot. A small central unit contains two ball joints which are releasably clamped via a single actuation. Bone fasteners, such as bone pins or bone screws are releasably clamped, via a single actuation at each of two clamping units, and each of the clamping units is adjustably clamped to a carrier rod within a wide range of selected positions, which extends to the smallest of offsets from the central double-ball joint unit, by reason of the fact that the ball of each ball joint is the inner end of one of the respective carrier rods.
