Ovarian torsion in children is an uncommon cause of acute abdominal pain but mandates early surgical management to prevent further adnexal damage. The clinical presentation mimics other pathologies, such as appendicitis. We sought to more completely characterize ovarian torsion with respect to pain and ancillary studies, such as urinalysis. We ...

The median orthopedic surgery wait time in Canada is 33.7 weeks, thus alternative treatments for pathologies such as lumbar disc herniations (LDH) are needed. We sought to determine whether transforaminal epidural steroid injections (TFESIs) alleviate or merely delay the need for surgery. We retrospectively reviewed the charts of patients with ...

In Canadian hospitals, which are typically financed by global annual budgets, overuse of operating rooms is a financial risk that is frequently managed by cancelling elective surgical procedures. It is uncertain how different scheduling rules affect the rate of elective surgery cancellations. We used discrete event simulation modelling to represent ...

Orthopedic surgeons depend on the intraoperative use of fluoroscopy to facilitate procedures across all subspecialties. The versatility of the C-arm fluoroscope allows acquisition of nearly any radiographic view. This versatility, however, creates the opportunity for difficulty in communication between surgeon and radiation technologist. Poor communication leads to delays, frustration and ...

Operating rooms (ORs) are estimated to generate up to one-third of hospital waste. At the London Health Sciences Centre, prosthetics and implants represent 17% of the institution's ecological footprint. To investigate waste production associated with total knee arthroplasties (TKAs), we performed a surgical waste audit to gauge the environmental impact ...

In patients with coronary disease and aneurysm, ventricular reconstruction with revascularization is a surgical option. Details of patient selection and optimal surgical technique are still debated.
