Recent work in magnetically actuated microscale robots for biomedical or microfluidic applications has resulted magnetic actuation systems that can remotely command precise five-degree-of-freedom control of devices. This paper presents a new type system, which uses an array rotating permanent magnets to generate the same level over untethered devices with potential increased field and gradient strength minimal heat generation. In contrast previous permanent-magnet systems, system proposed...

A new system was implemented by the Association of American Medical Colleges called preference signaling program for 2022 to 2023 orthopaedic surgery residency match. Applicants were able signal 30 programs indicate high interest in a specific program. The purpose this study address how important an application cycle.A five-question survey sent participating Electronic Residency Application Service cycle. Contact information gathered through Accreditation Council Graduate Education website...

Recent work in magnetically-actuated micro-scale robots for biomedical or microfluidic applications has resulted electromagnetic actuation systems which can command precise five-degree-of-freedom control of simple magnetic devices at the sub-millimeter scale remote environments. This paper presents a new type system uses an array large, rotatable, permanent magnets to generate same level over untethered micro-robotic with potential increased field and gradient strength minimal heat...

Abstract: Glenohumeral bone loss is frequently observed in cases of recurrent anterior and posterior shoulder instability represents a risk factor for failure nonoperative treatment. Patients with suspected glenoid or humeral the setting should be evaluated thorough history physical examination, as well advanced imaging including computed tomography (CT) and/or magnetic resonance (MRI). In both instability, magnitude location determined, relationship between track (GT) any defects. While...

Resident work hours have been a recurring source of concern and controversy for many years. From the Spartan origins Halsted generic model surgical service at Johns Hopkins in 1897 to present, there major tensions between educational needs learners workload demands patient care, resulting, times, classic labor-management confrontations about conditions.The first systematic reports resident began emerge late 1960s early 1970s. In 1979, American Medical Association conducted its national,...

Background Surgical fixation of midshaft clavicle fractures with a single 3.5 mm superior clavicular plate has been associated high rate hardware removal due to symptomatic hardware. Because this, dual-plating techniques lower-profile implants have proposed. However, systems disadvantages, including increased cost and surgical morbidity. The aim this study was define the for all fractures.Methods We retrospectively reviewed information on patients from 2014 2018 at level 1 trauma institution...

Parvimonas micra is a bacterium normal to oral and gastrointestinal flora that has been implicated in cases of discitis, osteomyelitis, prosthetic joint infections, often involving dental procedures or periodontal disease. It an extremely rare cause infection outside these circumstances. We describe case septic arthritis the native hip due P. micra.

Introduction: Orthopaedic surgery has consistently been one of the most competitive specialties in US residency selection process. This is due part to steady upward trend average applications received per program and submitted applicant, which growing concern. With implementation Preference Signaling Program, total number now dropped for first time many years, indicating signaling may improve application The hypothesis that led a decrease sent by applicants programs. Methods: A 7-question...

Supracondylar humerus fractures are common injuries encountered by orthopaedic surgeons.  Closed reduction and percutaneous pin fixation is classically considered the standard of care treatment for these injuries, as this method minimizes trauma to soft tissues, associated with few complications, have a high rate success.  However, loss fixation, when occurring, can lead devastating cosmetic, functional, neurological complications.  We present case study displaced...
