BACKGROUND Children with lower-limb-length discrepancy require repeated radiographic assessment for monitoring and as a guide for management. The need for accurate assessment of length and alignment is balanced by the need to minimize radiation exposure. We compared the accuracy, reliability, and radiation dose of EOS, a novel low-dose upright biplanar(More)
PURPOSE The objective of this systematic review was to determine the efficacy of anatomic Bankart repair in patients with a first-time shoulder dislocation compared with either arthroscopic lavage or traditional sling immobilization. METHODS We searched the Cochrane Central Register of Controlled Trials, Medline, Embase, CINAHL, Web of Science, LILACS,(More)
OBJECTIVE Most of the evidence regarding complications following total hip arthroplasty (THA) and total knee arthroplasty (TKA) is based on studies of patients with osteoarthritis (OA), with little being known about outcomes in patients with rheumatoid arthritis (RA). The objective of the present study was to review the current evidence regarding rates of(More)
STUDY DESIGN Observational. OBJECTIVE The objectives of this study were to determine the range of clinical magnification error in lateral spinal digital radiographs, and to determine the effect of body mass index (BMI) on this error. SUMMARY OF BACKGROUND DATA The magnification error in plain radiographs is often estimated at 15% to 30%. The variability(More)
BACKGROUND There is increasing evidence that a significant proportion of randomized trials in medicine, and recently in orthopaedics, do not go on to publication. PURPOSE The objectives of this study were (1) to determine publication rates of randomized controlled trials in sports medicine that have been registered with (CTG) and (2) to(More)
STUDY DESIGN Clinical case series. OBJECTIVE The primary objective of this study was to evaluate the clinical accuracy of computer-assisted two-dimensional fluoroscopy (2D-CAS) for the percutaneous placement of lumbosacral pedicle screws. SUMMARY OF BACKGROUND DATA Loss of visual anatomic landmarks and reduced tactile feedback increases the risk of(More)
BACKGROUND Because individuals with osteoarthritis (OA) avoid physical activities that exacerbate symptoms, potentially increasing risk for cardiovascular disease (CVD) and death, we assessed the relationship between OA disability and these outcomes. METHODS In a population cohort aged 55+ years with at least moderately severe symptomatic hip and/or knee(More)
BACKGROUND The rates of total joint arthroplasty (TJA) of the hip and knee have increased in North America over the last decade. While initially designed for elderly patients (>70 years of age), several reports suggest that an increasing number of younger patients are undergoing joint replacements. This suggests that more people are meeting the indication(More)
OBJECTIVE Most of the evidence regarding complications following total hip arthroplasty (THA) and total knee arthroplasty (TKA) are based on patients with osteoarthritis (OA); less is known about outcomes in rheumatoid arthritis (RA). Using a validated algorithm for identifying patients with RA, we undertook this study to compare the rates of complications(More)
OBJECTIVE To examine whether total joint arthroplasty of the hip and knee reduces the risk for serious cardiovascular events in patients with moderate-severe osteoarthritis. DESIGN Propensity score matched landmark analysis. SETTING Ontario, Canada. PARTICIPANTS 2200 adults with hip or knee osteoarthritis aged 55 or more at recruitment (1996-98) and(More)
