DEVICE FOR THE DETERMINATION OF REDUCTION PARAMETERS FOR THE SUBSEQUENT REDUCTION OF A FRACTURED BONE

摘要

The method for the determination of reduction parameters comprises: A)measuring points on the surfaces of the corresponding bones of interest at thepatient's left and right side of the body; B) establishing a plane of symmetrycontaining an anterior-posterior axis and a proximal-distal axis; C) a mirrorimage of the patient's non-fractured bone is generated symmetrically to theplane of symmetry; and D) the reduction parameters are then determined bycomparison of the coordinates of the points at the fractured bone with thecoordinates of the points within the mirror image. The device according to theinvention comprises: A) a cylindric or prismatic reference bar; B) clampsdisplaceable on and fastenable to the reference bar; C) screws or pinsscrewable into the bone transversely to the reference bar within the clamps;and D) an adjustable clamp to fasten a pin capable of being set with its tipto desired points on the surface of the bone.
