Multicenter Study Clinical TrialAngular-stable locked intramedullary nailing of two-part surgical neck fractures of the proximal part of the humerus. A multicenter retrospective observational study.
The ideal fixation technique for the treatment of proximal humeral fractures remains unclear. In the present study, we evaluated the experience of three surgeons with the treatment of two-part surgical neck fractures with angular-stable intramedullary fixation. ⋯ Patients who were managed with locked angular-stable intramedullary nailing of two-part surgical neck proximal humeral fractures via an articular entry point had reliable fracture-healing, favorable clinical outcomes, and little residual shoulder pain.

Comparative StudyA population-based comparison of the incidence of adverse outcomes after simultaneous-bilateral and staged-bilateral total knee arthroplasty.
It is unclear whether simultaneous-bilateral total knee arthroplasty is as safe as staged-bilateral arthroplasty is. We are aware of no randomized trials comparing the safety of these surgical strategies. The purpose of this study was to retrospectively compare these two strategies, with use of an intention-to-treat approach for the staged-bilateral arthroplasty cohort. ⋯ Simultaneous-bilateral total knee arthroplasty was associated with a clinically important reduction in the incidence of periprosthetic joint infection and malfunction within one year after arthroplasty, but it was associated with a moderately higher risk of an adverse cardiovascular outcome within thirty days. If patients who are at higher risk for cardiovascular complications can be identified, simultaneous-bilateral knee arthroplasty may be the preferred surgical strategy for the remaining lower-risk patients.

Comparative StudyVariations in the use of internal fixation for distal radial fracture in the United States medicare population.
Distal radial fractures affect an estimated 80,000 elderly Americans each year. Although the use of internal fixation for the treatment of distal radial fractures is becoming increasingly common, there have been no population-based studies to explore the dissemination of this technique. The aims of our study were to determine the current use of internal fixation for the treatment of distal radial fractures in the Medicare population and to examine regional variations and other factors that influence use of this treatment. We hypothesized that internal fixation of distal radial fractures would be used less commonly in male and black populations compared with other populations because the prevalence of osteoporosis is lower in these populations, and that use of internal fixation would be correlated with the percentage of the patients who were treated by a hand surgeon in a particular region. ⋯ The use of internal fixation for the treatment of a distal radial fracture differs widely among geographical regions and patient populations. Such variations highlight the need for improved comparative-effectiveness data to guide the treatment of this fracture.

Orthopaedic resident and program director opinions of resident duty hours: a national survey.
The Accreditation Council for Graduate Medical Education (ACGME) established national guidelines for resident duty hours in July 2003. Following an Institute of Medicine report in December 2008, the ACGME recommended further restrictions on resident duty hours that went into effect in July 2011. We conducted a national survey to assess the opinions of orthopaedic residents and of directors of residency and fellowship programs in the U.S. regarding the 2003 and 2011 ACGME resident duty-hour regulations and the effects of these regulations on resident education and patient care. ⋯ This national survey indicated significant differences between the opinions of orthopaedic residents and program (residency and fellowship) directors regarding the 2003 ACGME resident duty-hour regulations and the effects of these regulations on resident education and patient care. However, both residents and program directors agreed that the further reductions in duty hours in the 2011 rules may be detrimental to resident education and patient care.
