title: Reduced radiation exposure in orthopaedic surgery. Experience with video disc recording in nailing of fractured hips.
abstract: Radiation exposure from conventional fluoroscopy and from video disc recording was estimated during routine nailing of hip fractures. Mean fluoroscopic time with conventional fluoroscopy was 385 +/- 168 s. and with video disc recording 24 +/- 9 s. The time required for the X-ray system to form one television image, as well as the actual radiation exposure, were measured on a phantom under conditions that simulated hip nailing. Radiation exposure was 90% less with video disc recording than with conventional fluoroscopy. The use of a video disc recorder in orthopaedic operations requiring radiographic control is strongly advocated.
