摘要： A non-opposed surgical reduction clamp 10 is provided which has a drill guide 40 integrally formed with a guide leg 20 of the reduction clamp 10. The reduction clamp 10 also includes a reference leg 50 pivotably connected to the guide leg 20 through a pivot 70. The reference leg 50 includes a sharpened tip 57 at a tip thereof which can penetrate into a surface of a bone somewhat to prevent slippage of the reference leg 50. The drill guide 40 has an inner cylindrical surface 44 to provide an alignment axis Z for location of bone fixation structures, such as K-wire, pins or screws for reattachment and fixation of fractured bone fragments. Alignment axis Z of the drill guide 40 is in a common plane with the sharpened tip 57 of the reference leg 50, but extends beyond the sharpened tip 57 of the reference leg 50. Ends of the reference leg 50 and guide leg 20 opposite the sharpened tip 57 and drill guide 40 are provided with handle loops 30, 60 and clamp tabs 32, 62 to allow the reduction clamp 10 to be easily manipulated by a surgeon and clamped into position. The reduction clamp 10 is particularly configured to provide for reattachment of a lower tip H of a tibia T and to reattach a lower end E of a fibula F within the ankle A of a human patient. Precise orientation of the bone fixation structures such as wire K is provided without requiring a fully opposed reduction clamp.
