A retractor for opening and holding open an incision to allow a surgeon ready access through the incision during an operation or the like. A plurality of substantially opposed flesh engaging blades for engaging the sides of a surgical incision are pivotally mounted on a body which is provided with an aperture for placement over the surgical incision. A trigger is operatively coupled to the plurality of flesh engaging blades to cause the blades to simultaneously diverge from one another to thereby open the surgical incision and to allow the surgeon access into the surgical incision through the aperture in the body.

Retractor

An extension is provided for being nonrotatably fixed to a lag screw that is to be anchored to the head of a femur or other bone in a manner so as to allow compression to be applied to a fracture. The extension extends outward of the bone when attached to the lag screw and when the lag screw is anchored to the bone to allow a compression plate to be easily positioned thereon. The cross-section of the extension is substantially the same as the cross-section of the lag screw to allow the compression plate to be easily and quickly passed onto the lag screw from the extension once the compression plate has been positioned on the extension.
