Alcohol is a well-known analgesic, although excessive alcohol use can lead to hyperalgesia and heightened negative affect. This cross-sectional study examined associations between alcohol use, self-reported pain, and negative affective symptoms in two distinct cohorts of patients vulnerable to chronic pain: individuals undergoing total knee arthroplasty (TKA) surgery and a cohort of people with HIV (PWH). Participants were enrolled in two clinical studies: a retrospective study of patients undergoing TKA and a longitudinal study of PWH, the New Orleans Alcohol Use in HIV (NOAH) cohort. Based on the Alcohol Use Disorders Identification Test – Consumption (AUDIT-C) score, participants in both …

The Influence Of Perioperative Education On Postoperative Digestive Restoration, Christian Cedeno

Doctor of Nursing Practice Scholarly Project

The human body often needs encouragement to return to its natural state of functioning following intraoperative and postoperative drug therapy. Anesthesia can sedate the gastrointestinal tract and frequently requires medical and physical interventions to allow the body to return to full functionality. There are several methods thought to be beneficial in overcoming of this condition, and some have proven their significance more so than other methods. This project seeks to measure the power-of-knowledge methodology via a chart review of individuals specifically educated on what they can expect in the postoperative phase of care compared to those that receive routine education. …

Comparison Of Gluteal Muscle Central Activation In Individuals With And Without Patellofemoral Pain, Michael Carpio, John S. Donohue, Jacob P. Kissman

UNLV Theses, Dissertations, Professional Papers, and Capstones

Purpose/Hypothesis: Individuals with patellofemoral pain (PFP) often present with knee valgus during weight-bearing activities. Weakness in the gluteal muscles is thought to contribute to this condition, but recent studies suggest that hip weakness might be a secondary problem in this population. Central nervous system adaptations have been noted in persons with PFP, which can lead to altered muscle function, faulty movement patterns, and poor function. Experimentally, central activation can be quantified by a central activation ratio (CAR) via superimposed burst (SIB) during a maximum voluntary isometric contraction (MVIC) where the ratio of volitionally activated motor units to total motor units …

Can Flywheel Training Serve As A Viable Intervention For Dynamic Strength Index Based Programs?, Jeffrey Ruiz

Doctorate in Kinesiology

The purpose of this case series was to examine the effects that flywheel training had on a person’s dynamic strength index in comparison to concurrent training (DSI). It has been shown that with strength training alone there can be an overall decrease in the DSI, due to an increase the IMTP peak force and no significant change in the CMJ performance (Comfort et al., 2018). Flywheel training’s effect on the DSI specifically have not been previously examined. It was hypothesized that a regimented flywheel training intervention will demonstrate an

Sirt6 Deficiency Promotes Senescence And Age-Associated Intervertebral Disc Degeneration In Mice, Pranay Ramteke, Bahiyah Watson, Mallory Toci, Victoria Tran, Shira N Johnston, Maria Tsingas, Ruteja Barve, Ramkrishna Mitra, Richard Loeser, John Collins, Makarand Risbud

Department of Orthopaedic Surgery Faculty Papers

Intervertebral disc degeneration is a major risk factor contributing to chronic low back and neck pain. While the etiological factors for disc degeneration vary, age is still one of the most important risk factors. Recent studies have shown the promising role of SIRT6 in mammalian aging and skeletal tissue health, however its role in the intervertebral disc health remains unexplored. We investigated the contribution of SIRT6 to disc health by studying the age-dependent spinal phenotype of mice with conditional deletion of Sirt6 in the disc (Acan^CreERT2; Sirt6^fl/fl). Histological studies showed a degenerative phenotype in knockout mice …

Efficacy Of Platelet Rich Plasma On Thumb Basal Joint Osteoarthritis: A Narrative Review, Vrushank Shah, Alexander King

Rowan-Virtua Research Day

Platelet-rich plasma (PRP) has emerged as a potential treatment for carpometacarpal (CMC) joint osteoarthritis, with studies suggesting it may offer more durable symptom relief compared to corticosteroids. A comprehensive review of four studies, including two randomized controlled trials (RCTs), a retrospective study, and a pilot study, revealed that both PRP and corticosteroid injections led to short-term improvements in pain and function. However, PRP demonstrated significantly better long-term outcomes, with VAS scores decreasing from 75 to 20 in the PRP group at 12 months, compared to a modest reduction from 70 to 65 in the corticosteroid group. Additionally, PRP showed a …

The Relationship Between Running Cadence And Stress Fractures In Competitive Distance Runners, Jason A. Richwall

Rowan-Virtua Research Day

Running is one of the most popular sports and forms of exercise worldwide. Stress fractures are a common and potentially season-ending injury among competitive distance runners, with recurrence rates as high as 22%. Biomechanical factors, including running cadence, have been implicated in injury risk, but their precise role remains an area of active investigation. This literature review examines the relationship between cadence and stress fractures, drawing data from both observational and experimental studies. Observational studies suggest that low cadence and rearfoot striking are associated with increased risk of bone stress injuries. Experimental studies reinforce these findings, demonstrating that increased cadence …

Second-Site Periprosthetic Joint Infection After Subsequent Primary Hip Or Knee Arthroplasty, Daniel Nikolaidis, Devin Young, Andrew Steffensmeier, Robert Runner, Mark Karadsheh

Posters

Periprosthetic joint infections (PJI) can arise anytime in the lifetime of a patient. Therefore, patients who have multiple prosthetic joints are at risk for developing multiple PJIs. Polyarticular PJI can be classified as either synchronous or metachronous. Synchronous PJIs present simultaneously in two or more joints. Metachronous PJIs (MPJI) occur in two or more joints after a disease-free period. Incidence of MPJI varies in the literature from 8-20%.1

Known risk factors associated with MPJI include Rheumatoid Arthritis, sepsis or SIRS, infection with MRSA, ≥3 revision arthroplasties, longer length of stay in the hospital, and an index TKA PJI.2

Metachronous Periprosthetic Joint Infection In Patients With Multiple Arthroplasties At Index Infection, Devin Young, Daniel Nikolaidis, Andrew Steffensmeier, Robert Runner, Mark Karadsheh

Posters

Periprosthetic joint infection (PJI) is a devastating complication of one of the most successful surgeries in medicine. About 1% to 2% of patients will develop PJI after primary total hip arthroplasty (THA) or primary total knee arthroplasty (TKA) [1]. The 5-year patient survival rate of THA PJI is estimated to be worse than that of common cancers, such as breast cancer [2]. The burden of this disease is likely to increase exponentially as the population ages and the number of patients undergoing total joint arthroplasties increases in the future [3].

Most devastating is what Murray et al deem as metachronous …

The Use Of Intramedullary Screw For Fixation Of Distal Ulnar Fractures, Adam Lencer, John Pignataro, Justin Le, Joyce Daniel Suarez, Michael Rivlin

Rowan-Virtua Research Day

Background

Distal ulna fractures frequently accompany distal radius fractures but are often underappreciated in both clinical and research contexts. While conservative management is frequently employed, particularly following volar locking plate (VLP) fixation of the radius, certain indications, such as distal radioulnar joint (DRUJ) instability, comminution, or high-energy trauma, may necessitate surgical fixation. This study evaluates patient-reported outcomes among patients with distal radius fractures treated operatively, comparing those with and without concomitant distal ulna fractures, and further stratifying based on the method of ulna fixation.

Methods

This retrospective review included 477 patients treated operatively for distal radius fractures by a single …

A Twist Of Fate: A Case Of Spiral Humerus Fracture After Arm Wrestling, Alec Mirchandani, James Espinosa, Alan Lucerna

Rowan-Virtua Research Day

Fractures of the humerus are relatively uncommon, with spiral fractures typically resulting from rotational forces. This case report describes a 25-year-old male who sustained a right-sided spiral humerus fracture during an arm-wrestling match. The diagnosis was confirmed through radiographic imaging, and the fracture was successfully managed with closed reduction and posterior long arm splinting. This case highlights the importance of recognizing less common mechanisms of injury, like arm wrestling, in the context of humeral fractures. It also emphasizes the effective non-operative treatment of such fractures in young, healthy individuals.

Rothman Institute Papers

Study DesignReliability study.ObjectivesThe radiographic diagnosis of non-union is not standardized. Prior authors have suggested using a cutoff of < 1 mm interspinous process motion (ISPM) on flexion-extension radiographs, but the ability of practicing surgeons to make these measurements reliably is not clear.Methods29 practicing spine surgeons measured ISPM on 19 levels of ACDF from 9 patients. Surgeons relied on these measurements to report on fusion status. Inter-observer correlation co-efficients (ICC), standard error (SEM) and the minimum detectable difference (MD) of these measurements were calculated. We screened for clerical errors by checking measurements more than one standard deviation from the group mean.ResultsThe ICC for ISPM was .76 (.64; .88) with a SEM of 1 mm and a MD of 2.76 mm. Agreement on fusion status was moderate, with an ICC of .6 (.44; .76). After screening for and removing clerical errors, the ICC improved to .82 (.71; .91), SEM improved to .83 mm, and MD improved to 2.29 mm. Six reviewers had an ICC >.9. The ICC from these high performing reviewers was .94 (.9; .97), SEM was .45 mm, and MD was 1.26 mm.ConclusionsThe MD of 2.29 mm in our study group was not precise enough to support a cutoff of < 1 mm ISPM as the sole measurement technique in screening for non-union after ACDF, and there was only moderate agreement amongst surgeons on fusion status based on dynamic radiographs. More stringent techniques are necessary to avoid mis-diagnosing non-union in clinical studies. Future studies should consider auditing measurements to identify clerical errors.

Musculoskeletal Changes In Pregnancy: Implications For Long-Term Bone & Joint Health, Jaylyn Thompson, Clarence Julian Clark Ii, Nayarith Lopez, Aziza Ndaw

Rowan-Virtua Research Day

Pregnancy and lactation represent significant physiological challenges to maternal skeletal health, with substantial implications for both short and long-term musculoskeletal integrity. Research emphasizes that lactation induces notable skeletal adaptations, with up to 10% bone mineral density loss occurring in trabecular-rich regions such as the spine and hip (1,5). While most women experience substantial recovery post-weaning, the research indicates that recovery patterns vary significantly, with some women experiencing incomplete restoration of bone mass, potentially compromising long-term skeletal strength (3).

The underlying mechanisms driving these changes are primarily hormonal, with elevated parathyroid hormone-related protein (PTHrP) and decreased estrogen levels during lactation facilitating …
