The influence of posterior acromial morphology on outcomes and return to pushups in young patients undergoing arthroscopic posterior capsulolabral repair.

Background: Prior evidence has identified specific posterior acromial morphology as significantly associated with unidirectional posterior shoulder instability. The purpose of this study is to determine the influence of posterior acromial morphology on the outcomes of arthroscopic posterior capsulolabral repair (APCLR) for unidirectional posterior shoulder instability. Additionally, we sought to determine the influence of posterior acromial morphology on the rate and time to return to pushups following APCLR.

A High Rate of Return to Running Is Seen After Both Arthroscopic and Open Shoulder Surgery.

Purpose: To determine the percentage of patients who report the ability to run 1 mile at various time points after arthroscopic and open shoulder surgery.

Methods: We performed a retrospective review of prospectively collected data for all active-duty military patients aged 18 to 45 years who underwent shoulder surgery at a single institution over a 2-year period. The rehabilitation protocol discouraged running before 3 months, but all patients were able to return to unrestricted running at 3 months postoperatively.

The Iatrogenic Injury Potential of Self-adherent, Elastic Bandages in Finger Injuries.

Background: The use of a self-adherent, elastic bandage is a practical way to dress finger injuries. Multiple reports describe iatrogenic injuries from elastic bandages, ranging from skin necrosis to finger gangrene, necessitating amputations. This study investigated whether elastic bandages can compromise digital perfusion by occluding arterial blood flow in healthy volunteers and evaluated the utility of pulse oximetry as a monitoring tool for digital perfusion.

Prosthetic Hip Dislocations in Direct Anterior Versus Posterior Approach in Patients With Instrumented Lumbar Fusion.

Background: Instrumented posterior lumbar spinal fusion (IPLSF) has been demonstrated to contribute to instability following total hip arthroplasty (THA). It is unclear whether a supine direct anterior (DA) approach reduces the risk of instability.

Methods: A retrospective review of 1,773 patients who underwent THA through either a DA approach or a posterior approach at our institution over a 7-year period was performed.

Rate and time to return to shooting following arthroscopic and open shoulder surgery.

Background: There is limited information on return to shooting following shoulder surgery. The purpose of this study is to determine the rate and timing for resuming shooting a rifle following shoulder surgery.

Methods: We performed a retrospective review of prospectively collected data.

Formal Orthopaedic Surgery "Boot Camp" Curriculum to Optimize Performance on Acting Internships.

Orthopaedic surgery is one of the most competitive residency specialties in the National Residency Matching Program. To improve the odds of matching, senior medical students applying in the field participate in orthopaedic surgery away rotations with programs across the country. Students who do well on these rotations have a higher likelihood of matching because clinical performance is a principal criterion used by admissions committees to rank applicants.

Novel Technique for Osteosynthesis of Tongue-Type Calcaneus Fractures in Osteoporotic Bone: A Case Report.

Case: A 75-year-old woman with osteoporosis sustained a low-energy mechanism tongue-type calcaneus fracture. Index surgical fixation with conventionally described cannulated screws was complicated by early screw pull-out despite concomitant Achilles lengthening procedure. Using a novel technique, revision fixation was performed using a 5.

High Resiliency Linked to Short-Term Patient Reported Outcomes and Return to Duty Following Arthroscopic Knee Surgery.

Introduction: Resilience is a psychometric construct of a patient's ability to recover from adversity and has been used to predict outcomes but its use in orthopedics has been limited. The purpose of this study was to examine the association between resilience and outcomes.

Materials And Methods: We performed a retrospective analysis of prospectively collected data of patient who underwent sports knee surgery at a single institution performed by 6 orthopedic surgeons from January 2017 to December 2017.

Refuting the lipstick sign.

Background: Arthroscopic examination of the tendon has been described as the "gold standard" for diagnosis of tendinitis of the long head of the biceps (LHB). An arthroscopic finding of an inflamed and hyperemic LHB within the bicipital groove has been described as the "lipstick sign." Studies evaluating direct visualization in diagnosis of LHB tendinitis are lacking.

Development of a low-volume, highly sensitive microimmunoassay using computational fluid dynamics-driven multiobjective optimization.

Immunoassays are one of the most versatile and widely performed biochemical assays and, given their selectivity and specificity, are used in both clinical and research settings. However, the high cost of reagents and relatively large sample volumes constrain the integration of immunoassays into many applications. Scaling the assay down within microfluidic devices can alleviate issues associated with reagent and sample consumption.

The influence of oxytocin administration on responses to infant faces and potential moderation by OXTR genotype.

Rationale: Oxytocin is a neuropeptide that is associated with increases in social affiliative behaviors, particularly toward infants. However, no previous study has investigated healthy adults' responses to infant faces following oxytocin administration. In addition, given that preliminary evidence suggests that a single-nucleotide polymorphism of the oxytocin receptor (OXTR) gene, rs53576, may influence behaviors associated with parental sensitivity, we assessed whether such responses vary according to OXTR rs53576 genotype.

Reduced amygdala-orbitofrontal connectivity during moral judgments in youths with disruptive behavior disorders and psychopathic traits.

We used functional magnetic resonance imaging (fMRI) to investigate dysfunction in the amygdala and orbitofrontal cortex in adolescents with disruptive behavior disorders and psychopathic traits during a moral judgment task. Fourteen adolescents with psychopathic traits and 14 healthy controls were assessed using fMRI while they categorized illegal and legal behaviors in a moral judgment implicit association task. fMRI data were then analyzed using random-effects analysis of variance and functional connectivity.

Serotonin transporter genotype (5-HTTLPR) predicts utilitarian moral judgments.

Background: The psychological and neurobiological processes underlying moral judgment have been the focus of extensive recent research. Here we show that serotonin transporter (5-HTTLPR) genotype predicts responses to moral dilemmas featuring foreseen harm to an innocent.

Methodology/principal Findings: Participants in this study judged the acceptability of actions that would unintentionally or intentionally harm an innocent victim in order to save others' lives.

Oxytocin improves specific recognition of positive facial expressions.

Background: Oxytocin is a neuropeptide that is associated with increased trust. Perceptions of trustworthiness are associated with detection of positive facial affect, which suggests that oxytocin may enhance the recognition of positive facial affect. The present study tests this hypothesis.

The neural substrates of action identification.

Mentalization is the process by which an observer views a target as possessing higher cognitive faculties such as goals, intentions and desires. Mentalization can be assessed using action identification paradigms, in which observers choose mentalistic (goals-focused) or mechanistic (action-focused) descriptions of targets' actions. Neural structures that play key roles in inferring goals and intentions from others' observed or imagined actions include temporo-parietal junction, ventral premotor cortex and extrastriate body area.

Larger than life: humans' nonverbal status cues alter perceived size.

Background: Social dominance and physical size are closely linked. Nonverbal dominance displays in many non-human species are known to increase the displayer's apparent size. Humans also employ a variety of nonverbal cues that increase apparent status, but it is not yet known whether these cues function via a similar mechanism: by increasing the displayer's apparent size.
