Institutional Collective Action During COVID-19: Lessons in Local Economic Development.

At this point, little is known about local government responses to the economic crisis caused by COVID-19. This crisis is happening on Main Streets around the nation. This article examines how some local governments are taking collective action in partnership with other governments as well as with organizations at the local and regional levels.

Outcomes and predictors of mortality following periprosthethic proximal femoral fractures.

Background: Periprosthetic fractures are a well-documented, serious complication of joint arthroplasty, occurring in up to 11% of hip replacements. We examined periprosthetic femoral fractures over an 8 year period to determine the demographics, fracture pattern and management options and associated outcomes. Furthermore, we sought to determine which comorbidities resulted in increased risk of 12 month mortality after periprosthetic fractures about hip replacements Methods: A retrospective review of a prospective fracture database was conducted for the years 2007-2015.

An Imperfect Peace: Trends In Paramilitary Related Violence 20 Years After The Northern Ireland Ceasefires.

Background: The 1994 Northern Ireland ceasefire heralded a new beginning for the region after 30-years of violence. In the 20-years following the cessation of hostilities, paramilitary punishment attacks continue to occur in breach of the ceasefire. The aim of this study was to review trends in these attacks over the 20-years and their impact on orthopaedic services.

Factitious lymphoedema as a psychiatric condition mimicking reflex sympathetic dystrophy: a case report.

Introduction: Reflex sympathetic dystrophy can result in severe disability with only one in five patients able to fully resume prior activities. Therefore, it is important to diagnose this condition early and begin appropriate treatment. Factitious lymphoedema can mimic reflex sympathetic dystrophy and is caused by self-inflicted tourniquets, blows to the arm or repeated skin irritation.

Use of erythrocyte sedimentation rate and C-reactive protein level to diagnose infection before revision total knee arthroplasty. A prospective evaluation.

Background: Despite the widespread use of several diagnostic tests, there is still no perfect test for the diagnosis of infection at the site of a total knee arthroplasty. The purpose of this study was to evaluate the diagnostic test characteristics of the erythrocyte sedimentation rate and C-reactive protein level for the assessment of infection in patients presenting for revision total knee arthroplasty.

Methods: One hundred and fifty-one knees in 145 patients presenting for revision total knee arthroplasty were evaluated prospectively for the presence of infection with measurement of the erythrocyte sedimentation rate and the C-reactive protein level.

A biomechanical study comparing cortical onlay allograft struts and plates in the treatment of periprosthetic femoral fractures.

Background: Periprosthetic femoral fractures with well-fixed femoral components can be difficult to manage and internal fixation is usually necessary. This study was designed to determine the effect of cable plate, strut allograft and combined plate and strut allograft fixations of periprosthetic femoral fractures.

Methods: A transverse fracture at the level of the tip of the femoral stem was simulated in six cadaveric femurs.

Dislocation of the rotating platform after low contact stress total knee arthroplasty.

From a one-surgeon series of 2485 patients, we report on 10 patients with rotating platform dislocation after primary Low Contact Stress total knee arthroplasty. All dislocations occurred within 2 years of the index procedure. Of the 10 patients, nine required open reduction.

Migration of intrapelvic cement after total hip arthroplasty.

Intrapelvic extrusion of cement during total hip arthroplasty is a frequent occurrence. We report a case in which the intrapelvic cement mass broke free 3 years after the primary procedure and migrated proximally to lie against the posterior abdominal wall, resulting in intractable groin pain. The patient was relieved of pain after removal of the cement mass.
