A femoral gauge for sizing a femoral head implant and locating osteophytes or structural abnormalities comprising a gauge portion, the gauge portion having a concave gauge surface and an opposing back surface, the gauge surface defined by a pair of opposing lengthwise sides and a pair of widthwise sides, the gauge surface having a substantially spherical contour, the spherical contour sized for selection of a correspondingly sized femoral head implant, and a handle portion extending from the gauge portion, the handle portion positioned and configured for use in positioning the gauge surface. A plurality of different sized gauges can be provided. Areas of potential infringement can be located by rotating the femoral gauge around the juncture of the natural or implant femoral head and the natural femoral neck. Areas of impingement are removed until the femoral gauge can be rotated around the juncture without lifting off of the femoral head. |
