Abstract: | The role of the image intensifier has become an essential one in orthopaedic surgery for the intra-operative assessment of fracture reduction and implant placement. One of the commonest procedures in the orthopaedic theatre is the Dynamic Hip Screw (DHS) procedure. The DHS is designed to provide strong and stable internal fixation of a variety of fractures of the proximal femur with minimal soft tissue irritation Since Image Intensifier screening is commonly utilised in orthopaedic theatres there has been concern regarding the cumulative radiation dose to surgeons and theatre personnel due to high levels of screening times achieved in certain procedures. This research study was designed to correlate the level of experience of surgeons & radiographers and screening times during dynamic hip screw procedures. The aim is to ensure that screening time and radiation dose to patients and health care professionals in the orthopaedic theatre at St. Luke's Hospital are kept to a minimum. The investigation involved a non- experimental retrospective study performed on a sample of 76 patients who underwent a dynamic hip screw procedure. The researcher collected the data in the form of a structured checklist. From the results it was found that screening time and dose have a linear correlation to each other i.e. the higher the screening time, the higher is the dose. As expected more experienced radiographers had lower screening times when compared to junior radiographers. However, overall results showed that this difference is not statistically significant. There was no apparent difference between the various surgeons involved in the study that suggested that the screening time is effected by the surgeon. However, it was found that there was a positive relationship between screening time and complications during the operation. The major the complications the longer was the screening time. It was also confirmed from this study that radiation dose has a strong positive correlation to patient thickness. The thicker the patient the higher is the radiation dose. Since the data collected was mostly quantitative, some statistics could be worked out to make sense of the data collected from the structured checklist transforming it into information and this manipulation made it possible to draw out light on the research questions asked, confirm literature findings and suggest some recommendations. |
