Abstract:
We undertook this study to determine the amount of scattered radiation received by the primary surgeon, assistant and patient during dynamic hip screw fixation for proximal femoral fractures. Data was collected from fifty patients. Five registrars were included as operating surgeon and four senior house officers as assistant surgeon. Radiation was monitored by thermo luminescent dosimeters placed on the surgeon and assistant. The approximate distance of surgeon and assistant from the operative site was measured. A dosimeter on the unaffected hip of patients measured the radiation to the patient. The results show that the surgeon's dominant hand receives the highest dose of radiation and radiation exposure is dependent on the experience of the operator. Our study concludes that exposure to radiation during this procedure is well below the toxic levels; however greater awareness is needed for harmful effects of exposure to long term low dose radiation.

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
