Surgical training in the UK is under increasing pressure with a high demand for service provision. This raises concerns about the resultant negative impact this is having on training opportunities for surgical trainees in theatre due to a high demand for surgical procedures to be performed expediently by consultants. This is due to the assumption that trainee take significantly longer time to operate in theatre and thus result in a slow progress of theatre lists. Our study evaluated the differences in operative time between orthopaedic trainees and orthopaedic consultants, as well as provide realistic timings for each stage encompassed within the entire duration a patient is in theatre. From our trauma unit electronic theatre database, we retrospectively collected data for six Joint Committee of Surgical Training (JCST) mandatory procedures. Information collected included patients' ASA grading, total surgical time and grade of surgeons. A total of 956 procedures were reviewed: 71.8% hip procedures, 14.2% intramedullary nail fixations and 14.2% ankle fixations. 46.2% and 53.8% of the procedures were performed by consultants and trainees as first surgeon, respectively. On average, consultants were found to be 13 minutes quicker in performing the hip procedures and this difference was found to be statically significant (p < 0.05). However, trainees were found to be quicker in performing intramedullary femoral nailings and simple ankle fixations, but consultant were faster at performing intramedullary tibial nailings and complex ankle fixations. However, the differences were not found to be statistically significant (p > 0.05).
Conventional culture techniques have poor sensitivity for detecting bacteria growing in biofilms, which can result in under-diagnosis of infections. Sonication of biofilm colonised orthopaedic biomaterials can render bacteria in biofilm more culturable, thereby improving diagnosis of orthopaedic implant infections. Prosthetic joint infection (PJI) is a potentially devastating complication in arthroplasty. Biofilm formation is central to PJI offering protection to the contained bacteria against host defence system and antimicrobials. Orthopaedic biomaterials generally have a proclivity to biofilm colonisation. Conventional culture technique has a low sensitivity for detecting bacteria in biofilm. Sonication can disrupt bacteria biofilms aggregations and dislodge them from colonised surfaces, rendering them culturable and consequently improve the diagnosis of otherwise culture-negative PJI. We investigated the effect of ultrasonication on biofilms adherent to poylmethylmethacrylate PMMA cement.Summary Statement
