The apparatus is composed of a traction mechanism (5) and an imaging mechanism (10) and is mounted on an operating table (1). There are two x-ray tubes (13, 15) and two image intensifiers (14, 16) suitable positioned in two different planes on a bearing arm (11) in the imaging mechanism (10) in order obtain proper anterior, posterior and lateral x-ray image of the fractured area. Vertical x-ray tube (13) and vertical image intensifier (14) are positioned in order to obtain anterior-posterior hip image at vertical (coronal) plane. Horizontal x-ray tube (15) and horizontal image intensifier (16) are positioned in order to obtain lateral hip image at horizontal (sagittal) plane. Following detracting fractured parts from each other through the traction mechanism (5); positions of the implants (screw-wire-stud etc.) to be advanced to the bones are determined by using the imaging mechanism (10). |
