title: Blind zone determination of the femoral head.
abstract: An easily learned and applied method of accurately determining the blind zone of the femoral head is presented. This method is based on a geometric analysis of individual pins relative to the subchondral plate as apparent on mutually perpendicular roentgenograms. This method can be used with fluoroscopy or plain radiographs for intraoperative or postoperative evaluation.
