AbstractA bone clamp for insertion into a surgical incision perpendicular to a bone fracture has a ratchet mechanism. The bone clamp includes a scissor portion and a clamping portion. The scissor portion includes a pair of scissor arms, pivotally connected to one another, each having a finger loop at one end. Cooperating components of the ratchet mechanism are carried on each scissor arm, permitting a stepwise reduction in distance between the loops and between terminal ends of the scissor arms through the pivotal connection while preventing separation of the loops. The clamping portion includes a first elongated member pivotally connected at one of its ends to the terminal end of one of the scissor arms with a gripping point at another end. A second elongated member is pivotally connected to the terminal end of the other scissor arm. The first and second elongated members are slidably mounted to one another along their longitudinal axes. A hooked portion is disposed at the free end of the second elongated clamp member, terminating in a gripping point in alignment with, and opposing, the gripping point of the first elongated member. By mounting a pair of bone clamps in accordance with the invention side by side on a slide bar, with at least one of the bone clamps slidably mounted and securable at desired locations along the slide bar, fractured bone segments may be approximated.
