Chronic Adaptations of the Ulnar Nerve in Professional Baseball Pitchers: Ulnar Nerve Adaptations in Pitchers.

Context: Screening programs to identify negative ulnar nerve adaptations in throwing athletes can help minimize injury risk and individualize treatment programs prior to the onset of symptoms. However, it is currently unclear how the ulnar nerve structurally adapts chronically in professional baseball pitchers. Objective: To compare ulnar nerve ultrasound structural characteristics between the throwing (dominant) and non-throwing control (non-dominant) elbows in professional pitchers, with a secondary purpose of comparing ultrasound structural characteristics between subluxating and non-subluxating ulnar nerves.

Association of Antihypertensive and Statin Medication Usage With Postoperative Stiffness After Arthroscopic Rotator Cuff Repair: A Retrospective Cohort Study.

Background: Angiotensin-converting enzyme inhibitors (ACEi), angiotensin receptor blockers (ARB), and statins may be able to modulate postoperative stiffness, a major cause of morbidity after arthroscopic rotator cuff repair (aRCR).

Purpose: To determine whether there is an association between ACEi, ARB, or statin usage and stiffness after aRCR.

Study Design: Cohort study; Level of evidence, 3.

Tibial Tubercle Trochlear Groove Distance Does Not Correlate With Patellar Tendon Length in Patients Who Underwent Anterior Cruciate Ligament Reconstruction.

Purpose: To examine the relationship between tibial tubercle-trochlear groove (TT-TG) distance and patellar tendon length.

Methods: All healthy athletes who underwent anterior cruciate ligament reconstruction who had a magnetic resonance imaging (MRI) study of the knee on file between July 2018 and June 2019 at a single institution were retrospectively reviewed. Exclusion criteria included patients without an MRI study of the knee on file or with an MRI of insufficient quality precluding reliable calculation of TT-TG and patellar tendon length.

Physical Examination Versus Ultrasonography for Detection of Ulnar Nerve Subluxation in Professional Baseball Pitchers.

Background: Despite the importance of accurately detecting ulnar nerve subluxation in vulnerable athletes, few studies have compared the performance of physical examination and ultrasound in this population.

Purpose/hypothesis: The purpose of this study was to compare the diagnostic validity of physical examination versus ultrasound in detecting ulnar nerve subluxation at the cubital tunnel of the elbow in professional baseball pitchers. It was hypothesized that ultrasound would more sensitively detect ulnar nerve subluxation.

Prevalence of bilateral ulnar nerve subluxation among professional baseball pitchers.

Background: Radiographic and physical examination findings of ulnar nerve instability have been recognized in overhead throwing athletes, despite the fact that some of these abnormalities may be asymptomatic and represent adaptive changes. While recommendations for screening and early detection have been made that can adversely impact an athletes' career, the presence of bilateral ulnar nerve subluxation and its relationship with medial elbow symptoms has not been characterized in professional overhead throwing athletes.

Purpose: To characterize the prevalence of bilateral ulnar nerve subluxation among professional baseball pitchers.

Differences in the Severity and Location of Patellofemoral Cartilage Damage Between Instability Patients With and Without Patella Alta.

Background: Patella alta is a risk factor for recurrent patellar instability. Differences in chondral injury in patients with patellar instability between patella alta and patella norma have not been evaluated.

Purpose: To analyze whether preoperative cartilage damage differs in severity and location between patellar instability patients with and without patella alta.

Bankart Repair With or Without Concomitant Remplissage Results in Similar Shoulder Motion and Postoperative Outcomes in the Treatment of Shoulder Instability.

Purpose: To compare the results of patients who underwent Bankart repair with or without concomitant remplissage for treatment of shoulder instability.

Methods: All patients who underwent shoulder stabilization for shoulder instability from 2014 to 2019 were evaluated. Patients who underwent remplissage were matched to those patients who received no remplissage based on sex, age, body mass index, and date of surgery.

Increased rates of subjective shoulder instability after Bankart repair with remplissage compared to Latarjet surgery.

Hypothesis And Background: Controversy exists as to the ideal management of young active patients with subcritical glenoid bone loss and an off-track Hill-Sachs lesion, and the Latarjet and arthroscopic Bankart with remplissage are effective surgical options. The purpose of this study was to compare rates of recurrent instability and reoperation, as well as patient-reported outcome measures, between Latarjet and arthroscopic Bankart repair with remplissage surgery patients. The authors hypothesized that there would be no difference in rates of recurrent instability, reoperation, and postoperative outcomes between patients who underwent Latarjet surgery and patients who underwent Bankart repair with concomitant remplissage postoperatively.

Four-year outcomes for endoscopic sleeve gastroplasty from a single centre in India.

Background: Bariatric endoscopy has emerged for non-surgical treatment of obesity, providing a treatment option for weight loss and associated comorbidities. Outcomes of endoscopic sleeve gastroplasty (ESG) of 12 months have been published by our team and there is a need for longer follow-up period understanding the effects of ESG techniques.

Methods: This study was a retrospective review of all NBA players who were placed on the injury report during the preseason and first 4 weeks of the regular season as well as playoffs from the 2017-2018 through 2020-2021 NBA seasons. The data were compiled using publicly available injury reports.

Simulation of Onset of the Capillary Surface Wave in the Ultrasonic Atomizer.

The novel drug delivery system refers to the formulations and technologies for transporting a pharmaceutical compound in the body as it is needed to safely achieve its desired therapeutic effects. In this study, the onset vibrational amplitude of capillary surface waves for ultrasonic atomization spray is explained based on Faraday instability. Using ultrasonic frequency, the vibrational amplitude approached a critical point, and the liquid surface broke up into tiny drops.
