BACKGROUND Reoperation rates following open reduction and internal fixation (ORIF) of midshaft clavicle fractures have been described, but reported rates of nonunion, malunion, infection, and implant removal have varied. We sought to establish baseline rates of, and risk factors for, reoperations following clavicle ORIF in a large population cohort. (More)
BACKGROUND Evidence regarding the risk of end-stage osteoarthritis following cruciate ligament reconstruction is based upon small sample sizes and radiographic, rather than clinical, criteria. The goals of this study were to determine the risk of knee arthroplasty, a surrogate for end-stage osteoarthritis, following cruciate ligament reconstruction, and to(More)
BACKGROUND There is a lack of high-quality population-based literature describing the epidemiology of primary anterior shoulder dislocation. PURPOSE To (1) calculate the incidence density rate (IDR) of primary anterior shoulder dislocation requiring closed reduction (CR; "index event") in the general population and demographic subgroups, and (2) determine(More)
PURPOSE Shoulder instability frequently recurs in young patients without operative treatment. Both open and arthroscopic approaches to shoulder stabilization with labral repair and capsulorrhaphy have been described and are routinely used. Multiple trials have been conducted to compare these approaches, with multiple meta-analyses performed to synthesize(More)
BACKGROUND The rate of total shoulder arthroplasty (TSA) is rising, which has an impact on health care expenditure. One avenue to mitigate cost is outpatient TSA. There are currently no published reports of this practice. In this study, we determine the 30-day adverse event and readmission rates after outpatient TSA and compare these rates with inpatient(More)
OBJECTIVES Our main purpose was to investigate any relationship between noise exposure levels in the workplace, degree of hearing loss (HL), and the relative risk of accident (OR of single or multiple events). METHODS We conducted a retrospective study of 52 982 male workers aged 16-64 years with long-standing exposures to occupational noise over a 5-year(More)
There is accumulating epidemiological evidence that exposure to some solvents, metals, asphyxiants and other substances in humans is associated with an increased risk of acquiring hearing loss. Furthermore, simultaneous and successive exposure to certain chemicals along with noise can increase the susceptibility to noise-induced hearing loss. There are no(More)
PURPOSE The purpose of this systematic review was to synthesize the available Level I and Level II literature on platelet-rich plasma (PRP) as a therapeutic intervention in the management of symptomatic knee osteoarthritis (OA). METHODS A systematic review of Medline, Embase, Cochrane Central Register of Controlled Trials, PubMed, and(More)
INTRODUCTION The epidemiology of paediatric supracondylar fracture (SCF) fixation has not been evaluated at a population level. The purpose of this study was to: (1) determine the incidence density rate (IDR) of SCF fixation and (2) determine the rate of and risk factors for re-operation. METHODS Using administrative databases, all patients who underwent(More)
BACKGROUND Pseudoxanthoma elasticum (PXE) is a genetic multisystem disorder characterized by calcified dystrophic elastic fibres in skin, retina and arteries. Much of the earlier literature on pregnancy in PXE contained reports of severe complications, leading some healthcare providers to advise women with PXE against becoming pregnant and some women with(More)
