Can fluoroscopy radiation exposure be measured in minimally invasive trauma surgery?

Repeated use of X-rays in orthopedic surgery poses the problem of irradiation of patient and caregivers. Seven common minimally invasive bone trauma surgical procedures requiring image intensifier use were investigated: percutaneous K-wire fixation of the wrist, minimally invasive fixation plating of the wrist, percutaneous intramedullary nailing of the tibia and of the femur, short and long trochanteric nail fixation of trochanteric and sub-trochanteric fracture, and percutaneous fixation of thoracolumbar fracture. The study analyzed three parameters: dose area product (DAP), radiation duration, and skin entrance dose (SED). Data were collected from 15 successive implementations of each procedure. The aim of the study was to establish a database for this kind of bone trauma surgery and a hierarchy of the X-ray doses delivered. Percutaneous spinal osteosynthesis involved the highest dose, followed in decreasing order by long trochanteric nailing, femoral nailing, short trochanteric nailing, tibial nailing, wrist K-wire fixation and frontal wrist plate osteosynthesis. One short trochanteric nail procedure delivered the same DAP as 13 wrist K-wire fixation procedures, and one spinal osteosynthesis was equivalent to 13 short trochanteric nail or 174 wrist K-wire procedures. The anatomic area X-rayed appeared to be the main radiation dose factor. A database was established, but actual patient and staff radiation levels remained unknown.
