Overweight patients undergoing hip fracture surgery experience higher intra-operative radiation exposure, specifically in dose area product, irrespective of screening time. This highlights a need for radiation safety awareness for surgical staff.
Area of Science:
- Orthopedic Surgery
- Radiology
- Patient Safety
Background:
- Intra-operative radiation exposure is a concern in orthopedic procedures.
- Body Mass Index (BMI) may influence radiation dose during surgery.
Purpose of the Study:
- To investigate the correlation between patient BMI and intra-operative radiation exposure during femoral neck fracture fixation.
Main Methods:
- Retrospective review of 81 patients undergoing sliding hip screw fixation.
- Data collected included BMI, screening time, Dose Area Product (DAP), ASA grade, surgeon seniority, and fracture complexity.
Main Results:
- A significant positive correlation was found between Dose Area Product (DAP) and BMI.
- No significant relationship was observed between screening time and BMI.
- Overweight patients showed increased simulated stochastic risks and higher radiation doses.
Conclusions:
- Increased BMI is associated with higher radiation doses (DAP) during femoral neck fracture surgery.
- Surgeons, theatre staff, and radiographers must be aware of and mitigate increased radiation risks for overweight patients.
- While individual patient risk may be low, staff exposure is a significant concern.

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...
