Abstract

Abstract A multi-purpose surgical table and method of use is disclosed, the table having particular use in conjunction with a mobile Xray image intensification unit. The table provides an open area free of obstructions for the image intensifier of the image intensification unit to be located beneath the patient, permitting lateral and anterior-posterior views of an injured extremity or trunk of the body without change of position of the patient from an initial supine position on the table, without change in position of the table, and without change in the initial set position of the image intensification unit on the floor. The table has a sacral rest extending distally of a support pedestal. The sacral rest is substantially transparent to X-rays and free of any obstruction directly underneath. A perineal post substantially transparent to X-rays is mounted on the sacral rest. A leg support for the leg to be treated pivots vertically and horizontally about a pivot point coinciding with the anatomical axis of the hip joint of the injured leg. The leg support extends alongside the outer length of the leg at a sufficient height from the floor on which the table is resting to allow the image intensifier in its lowest position for anteriorposterior viewing and yet give sufficient clearance for the face of the image intensifier to be positioned closely adjacent or against the skin of the leg of the patient for both anteriorposterior and lateral viewing without movement of the patient or the table. In addition to obtaining the two standard views of the hip, shaft of the thigh bone, bones of the knee, lower leg and ankle, the table has additional features which allow the two standard views (anterior-posterior and lateral) of the head, neck, spinal column, pelvis, shoulder joint and arm to be obtained without movement of the patient from an initial supine position and without movement of the table. The table, in addition, provides a unique non obstructing way of obtaining abduction, adduction and flexion-extension on anatomic centers at the shoulder of an injured arm or at the hip of the injured or well leg, and means of holding the legs in any degree of such movement. The table also provides a means of obtaining flexion-extension of the knee on its anatomic center. The table is also useful for diagnosis, reduction of fractures, vascular surgery and other techniques.
