Purpose. The consequences of infection in orthopedic oncology patients are well known. Methicillin sensitive- and resistant Staphylococcus aureus (MSSA and MRSA, respectively) are common infecting organisms which may colonize patients pre-operatively. The prevalence of colonization in orthopedic oncology patients is unknown. We sought to prospectively establish the prevalence of MSSA and MRSA colonization in an orthopedic oncology patient population. Method. Beginning in September 2009, all oncology patients of a single surgical service were prospectively screened pre-operatively for MSSA and MRSA colonization using PCR nasal swabs as part of an infection control protocol. Patients identified as carriers underwent decolonization treatment peri-operatively. Results. One hundred thirty-nine oncology patients underwent 143 independent procedures with orthopedics as the primary service from September 1, 2009 August 31, 2010. MSSA/MRSA screening capture rate was 93%. Prevalence of MSSA colonization was 22% and MRSA colonization was 3.8%. MSSA colonization was not associated with malignant diagnosis (p=1.0), or recent chemo- or radiotherapy treatment (p>0.50 for both). All MRSA colonized patients had undergone inpatient oncology treatment or had occupational exposure to MRSA in the last year. Post-operative infection developed in 4/124 patients with type I surgical incisions (3.2%). Infecting organisms were coagulase negative Staphylococcus (n=2), MSSA (n=1), and Streptococcus (n=1). Conclusion. MSSA colonization rates in orthopedic oncology patients are similar to reported population values. MRSA colonization rates are low. Patient diagnosis or adjuvant treatments do not appear to influence colonization rates. MRSA colonization was only seen in patients with inpatient or occupational exposure to MRSA

Abstract. INTRODUCTION. With increasing use of fluoroscopy in Orthopaedic theatres in recent years, the occupational radiation exposure to the surgeons and the theatre staff has increased significantly. Thyroid is one of the most radio-sensitive tissues in the body, but there is a clear lack of awareness among theatre staff of risks of radiation to thyroid. METHODS. We prospectively reviewed the use of thyroid shield by the theatre staff in the orthopaedic theatre for two weeks period. We also recorded the number of fluoroscopic images taken and total radiation dosage for each case. RESULTS. Our results showed that of 249 staff in the theatres of which, only 35 people (14.2%) wore thyroid shields during fluoroscopy, whereas 100% were complaint with body protection shield. We noticed that only 30% of the surgeons, 40% of the scrub nurses and 5% anaesthetist use this, while 95% of the radiographers uses thyroid protection in theatre. Average total radiation during upper-limb procedures was 1.25 cGy, during lower-limb procedures it was 43.48 cGy. Total radiations were very high particularly during lower-limb nailing procedures (80.98 cGy). CONCLUSION. Extensive use of fluoroscopy has a stochastic effect (accumulative effect) on thyroid gland particularly, if the dose in higher than 65 cGy. Despite its availability, only 14% people use the thyroid protection shield. We must emphasise the use of thyroid protection shield to the Orthopaedic surgeons, particularly during lower-limb procedures

Aims

The use of fluoroscopy in orthopaedic surgery creates risk of radiation exposure to surgeons. Appropriate personal protective equipment (PPE) can help mitigate this. The primary aim of this study was to assess if current radiation protection in orthopaedic trauma is safe. The secondary aims were to describe normative data of radiation exposure during common orthopaedic procedures, evaluate ways to improve any deficits in protection, and validate the use of electronic personal dosimeters (EPDs) in assessing radiation dose in orthopaedic surgery.
