Fluoroscopy Versus Imageless Optical Navigation in Direct Anterior Approach Total Hip Arthroplasty.

Background: Utilization of the direct anterior approach (DAA) for total hip arthroplasty (THA) has risen in popularity. Accurate implant placement is a critical factor that influences patient outcomes. The goal of this study was to compare the accuracy and precision of fluoroscopy with imageless optical navigation in DAA THA.

The organizational and financial viability of an orthopedic trauma service.

Background: This study was designed to explore the effect of establishing an Orthopedic Trauma Service (OTS) on departmental revenue within an academic orthopedic department. The effect of the OTS on physician and resident perceptions of job satisfaction, education, and quality of patient care were also evaluated.

Methods: A proforma financial analysis was undertaken using an optimization model to predict the potential financial performance of an OTS before its implementation.

Disequilibrium between admitted and discharged hospitalized patients affects emergency department length of stay.

Study Objective: Most patients are admitted to the hospital through the emergency department (ED), and ED waiting times partly reflect the availability of inpatient beds. We test whether the balance between daily hospital admissions and discharges affects next-day ED length of stay.

Methods: We conducted a cross-sectional study of hospitals in metropolitan Toronto, served by a single emergency medical services provider in a publicly funded system.

Proximal femoral allograft treatment of Vancouver type-B3 periprosthetic femoral fractures after total hip arthroplasty. Surgical technique.

Background: Periprosthetic femoral fractures following total hip arthroplasty are becoming more prevalent. When a fracture occurs in a femur with substantial proximal bone deficiency, the surgical options for revision are limited. One option includes the use of a proximal femoral allograft.

Intracerebral haemorrhage in previously healthy adults following aerobic and anaerobic exercise.

Primary Objective: Intracerebral haemorrhage (ICH) without demonstrated tissue pathology in previously healthy adults has not been previously linked to anaerobic or aerobic exercise. The possible mechanisms and risk factors for ICH that may be found in a young, "healthy" adult are described.

Research Design: Case reports of two patients who suffered a frontal lobe ICH following aerobic and anaerobic exercise are presented.
