Peripheral Nerve Blocks Are Associated With Decreased Early Medical Complications, Dislocations, and Opioid Consumption Following Total Hip Arthroplasty.

Background: Peripheral nerve blocks (PNBs) may be utilized for postoperative pain control following total hip arthroplasty (THA). The purpose of this study was to evaluate the association between PNBs and postoperative complication rates, healthcare utilization, and opioid consumption following elective THA.

Methods: Opioid-naive patients who received PNBs on the same day as undergoing THA for degenerative etiologies were identified from a large national database and matched 1:5 to a control cohort using propensity scoring.

Posterolateral Corner Reconstruction: A Systematic Review and Meta-analysis of Biomechanical Studies.

Background: Surgical reconstruction is the standard treatment for injuries to the posterolateral corner (PLC) of the knee and can be performed using either a fibular-based or combined tibiofibular-based technique. Although some comparative studies have been performed, there is no consensus regarding the reconstructive approach that confers optimal biomechanical properties of the PLC.

Purpose: To perform a systematic review and meta-analysis to evaluate the biomechanical properties of the knee after PLC reconstruction with fibular-based and tibiofibular-based techniques.

Real-World Social Reward Processes are Linked to Momentary Positive Affect in Adolescent Girls.

Positive peer interactions are critical for adolescent development and well-being. Showing little interest in interacting socially with peers and/or extracting little reward from positive peer interactions can be markers of social anhedonia, which impacts many youths, especially girls, with social anxiety and depressive disorders. Reduced interest or reward in peer interactions may contribute to social anxiety and depression in girls through effects on positive affect (PA), though associations between social anhedonia and momentary PA have yet to be tested.

The Role of Neural Sensitivity to Social Evaluation in Understanding "for Whom" Social Media Use May Impact Emotional Health During Adolescence.

There is much interest in the role of social media (SM) in the current mental health crisis among teens. In this review, we focus on the question of "for whom" SM experiences have the strongest impact on emotional health, considering neural sensitivity to social evaluation as a potential vulnerability factor that makes youth more susceptible to the effects of SM. We first present behavioral evidence showing that sensitivity to social evaluation moderates the link between SM use and emotional health in youth.

Physical and mental demand during direct anterior total hip arthroplasty: Comparison of robotic-assisted and conventional techniques.

Introduction: The adoption of new techniques, such as the direct anterior (DA) approach, and technologies, such as robotic assistance, in total hip arthroplasty (THA) has the potential to alleviate the intraoperative physical and mental demand that surgeons experience. Therefore, the aim of this study is to compare the physical and mental demand of surgeons performing conventional DA THA with fluoroscopy and robotic-assisted DA THA without fluoroscopy.

Methods: Two orthopaedic surgeons completed bilateral DA THA's on six cadaveric specimens.
