Abstract:
The main objective of this study is to evaluate the radiation dose incurred by
medical staff and patients during orthopedic procedures, namely dynamic hip screw
(DHS), dynamic cannulated screw (DCS) and closed intramedullary nailing (IMN).
The entrance skin dose (ESD) for both staff and patients at different anatomic
locations was measured using lithium fluoride (LiF: Mg, P,Cu GR: 200)
thermoluminescence dosimeters (TLDs) and TLD reader (Fimel-France). The
ambient dose around C-arm machine was also measured using CONYII ionization
chamber. The mean values of fluoroscopic exposure factors for the procedures were
71±7 kVp, 1.3±0.6 mA and 0.68±0.13 min. The mean ESD was 0.26 and 7.9 mGy
for staff and patient, respectively. On the average, the ESD for staff at specific
anatomic locations was 0.15 ±0.02 (lens), 0.064 ± 0.01 (thyroid), 0.20±0.06 (chest),
0.23±0.2 (right hand) and 0.19±0.04 mGy for the left leg. The results revealed that
staff and patients received higher radiation doses during DHS relative to DCS
procedures; and that the orthopedist hands were most exposed than other organs.
