720 Dynamic Hip Screw vs Short Intra Medullary Nail - Which Is Safer for the Surgeon: A Retrospective Comparison of Radiation Exposure

Abstract Aim Dynamic hip screws (DHS) and short intra medullary (IM) nails are fixation methods used for neck of femur (NOF) fractures. Both require fluoroscopic assistance within the operating theatre, therefore exposing surgeon patient to ionising radiation. There is minimal literature investigating radiation exposure. Aims this study compare doses in each procedure estimate a normalised dose. Method Retrospective data analysis was carried out patients who underwent fluoroscopically assisted surgical management NOF fractures using DHS IM nail over 3-year-period. Data sourced electronic operative records Sectra PACS imaging software. Radiation dose parameters collected were cumulative milligrays (mGy), area product (DAP) (Gy.cm2) time exposure minutes seconds. Statistical performed SPSS statistical Results A total 56 treated with DHS, 46 (Short TFNA - Synthes). 79% cases extra capsular versus 100% nails. Cumulative group demonstrated mean 6.007mGy, compared 1.153mGy nail. Mean times 1:39 1:32 Conclusions Our showed difference significantly less when DHS. Additional should be considered safety hazard surgeon, theatre staff patients.
