Research Symposium

Background: The Rio Grande Valley (RGV) is a developing clinical research region characterized by its distinctive demographic profile that offers an opportunity to investigate diverse health issues. This pilot investigation seeks to identify the characteristics of patients diagnosed with bone metastasis and primary malignant bone neoplasia (PMBN) in the RGV. The main objective was to evaluate the demographic and clinical characteristics linked to bone metastases and PMBN in patients from the Rio Grande Valley. We hypothesized that older age and higher BMI individuals would have greater frequency of metastatic lesions compared to PMBN.

Methods: Data was gathered from the …

Demographic And Clinical Characteristics Of Patients With Benign Bone Tumors: Evidence Of Bimodal Age Distribution In A Hispanic Population, Blake C. Martin, Mohammad Khalil, Juan Lopez Alvarenga

Research Symposium

Background: As far as researchers know, there’s no way to prevent BBTs from forming. Although these tumors generally do not metastasize, they can still be dangerous as they may grow and compress healthy tissues and lead to poor outcomes. The principal objective was to evaluate the demographic and clinical characteristics linked to BBTs in individuals from the Rio Grande Valley. We hypothesized that older age, males, and higher BMI individuals would have greater frequency of BBTs.

Methods: This was a retrospective chart review and IRB approval was obtained prior to starting this study. We obtained medical charts for individuals who …

Characterizing Fracture Distribution By Sex, Age, And Body Region: Insights From A Regional Population Study, Blake C. Martin, Jared Hensley, Juan Lopez Alvarenga

Research Symposium

Background: This Rio Grande Valley (RGV) region of South Texas is a unique region that is impoverished and medically underserved. We conducted this study in order to further the knowledge of orthopedics in this unique, medically underserved community. We sought to determine if certain body regions, based on sex and age, were at increased risk for fracture in this population. We hypothesized that females would have increased fracture frequency at older ages while males would have increased fracture frequency at all other ages. We also hypothesized that femur and forearm fractures would be increased in females compared to males.

Methods …

Bone And Joint Infections: A Retrospective Chart Review Of The Medically Underserved Rio Grande Valley, Blake C. Martin, Chloe Harris, Manoj Peiris

Research Symposium

Background: The Rio Grande Valley (RGV) is a demographically unique region that is impoverished and medically underserved. Because of its unique patient population, this community may be at increased risk for bone and joint infections and the morbidity and mortality that follows. The goal of this study was to analyze individuals with osteomyelitis, septic arthritis, and periprosthetic joint infections and determine which infectious bone or joint conditions are most prevalent in the Rio Grande Valley and determine if there were any demographic disparities between the various types of bone and joint infections and healthy individuals. We hypothesized that age and …

Association Of Joint Disease With Demographic Factors In Clinical Populations Of The Rio Grande Valley, Blake C. Martin, Devian D. Baez, Juan C. Lopez-Alvarenga

Research Symposium

Background: The Rio Grande Valley (RGV) is a medically underserved, demographically unique population that warrants the exploration of various conditions, including joint conditions, such as osteoarthritis (OA), rheumatoid arthritis (RA), gout, ankylosing spondylitis (AS), psoriatic arthritis (PA), juvenile idiopathic arthritis (JIA), and septic arthritis (SA). We sought to determine the demographic disparities between the different types of common joint conditions in this community. We hypothesized that OA would follow national trends and be the most common joint condition in the Rio Grande Valley. We hypothesized that the demographics between the various joint conditions would vary depending on age, sex, BMI, …

Gut-Spine Connection: Unexplored Pathways To Improving Outcomes In Spinal Health And Disease, Anesu K. Murambadoro, Julia Saifetiarova, Priya Kale, Victor A. Bob-Yellowe, Paul Bonilla, Aun A. Bangash, Isabella Ortigoza, Anjana Ganesh, Mohammed S. Razzaque

Research Symposium

Introduction: Lumbar spinal fusion is among the most expensive procedures in the Medicare system, with costs exceeding $33 billion annually. Improving recovery outcomes for these procedures is critical, and emerging research suggests that microbiome-targeted therapies could play a key role. There is growing evidence linking spinal health with gut microbiota alterations, particularly through the gut-spine axis, which involves the gut-disc, gut-bone, and gut-immune interactions. This bidirectional relationship between gut microbiota and spinal health offers a novel approach for understanding recovery mechanisms. Additionally, magnesium deficiency, which is prevalent, may exacerbate both gut dysbiosis and poor bone health, contributing to chronic skeletal …

Evaluating Industry Relationships And Transparency: Insights From Orthopedic Surgeons In The Cms Open Payments Database, Anesu K. Murambadoro, Mario Keko, Edward Rodriguez, John J. Wixted

Research Symposium

Introduction: Industry payments to physicians may risk introducing bias into patient care. The Open Payments (OP) database, established by Physician Payments Sunshine Act, reports these payments to promote transparency. Orthopedic surgeons receive the highest industry payments especially in the category of royalties/licensing, prompting questions about conflicts of interest and whether the database accurately reflects the status across the specialty. We hypothesize that the OP database underrepresents the relationships that orthopedic surgeons have with industry. We seek to assess the validity of reported industry payments, particularly in the categories of royalties and licensing payments to determine how to improve transparency and …

Spine Surgery In South Texas: The Impact Of Rurality On Surgeon Demographics And Access To Care, Anesu K. Murambadoro, Kevin Garcia Valdez, Patrick De La Torre Schutz, Allison J. Mcadams, Anjali Rose Binoy, Kelsey Baker

Research Symposium

Introduction: Female representation in spine surgery remains low, with only 4% of orthopedic spine surgeons and 9% of neurosurgeons identifying as female. Studies have shown that factors such as societal perceptions, limited support for family planning, and a lack of mentorship deter women from pursuing surgical careers. We hypothesize that representation may be further impacted in US-Border regions. Specifically, over 90% of Texas' 32 border counties lack sufficient primary care services, including specialty care such as orthopedic surgery and neurosurgery, leading residents to seek care outside the region. Here, we sought to evaluate the demographics of spine surgeons (orthopedic and …

Can Oral Caffeine Decrease Postoperative Opioid Consumption Following Posterior Spinal Fusion In Adolescent Idiopathic Scoliosis? A Randomized Placebo-Controlled Trial., Anne E. Stuedemann, Richard M. Schwend, K Aaron Shaw, Nicolette Saddler, Michon Huston, Michael Benvenuti, Julia Leamon, Ashley K. Sherman, John Anderson

Manuscripts, Articles, Book Chapters and Other Papers

BACKGROUND: Current studies have examined the efficacy of opioid-sparing analgesics primarily in adult surgical populations, while fewer guide pediatric postoperative pain treatment. Caffeine exerts most of its biological effects by binding to adenosine receptors, which are important for modifying pain and inflammation. Caffeine's ability to modulate pain following posterior spinal fusion (PSF) for adolescent idiopathic scoliosis (AIS) has not been previously assessed.

METHODS: The hospital investigational drug study (IDS) pharmacy provided either a treatment dose or placebo dose of caffeine to be given to the patient and was also in charge of randomization for the study.

RESULTS: There were 24 …

Post-surgical spinal infection occurs in up to 20 % of patients, despite aggressive peri-operative antibiotic treatments. To improve prophylaxis, we have designed and evaluated an ultrasound-activated prophylactic antibiotic release system to combat post-surgical bacterial survival. Polylactic acid (PLA) clips (1 cm³) were 3D-printed with an interior reservoir (0.8 cm³) for carrying drug payload, specifically vancomycin (VAN). Under IACUC approval, clips were surgically implanted into the spines of sheep (n = 9) and swine (n = 2) by removing the spinous process at several levels of the lumbar spine. In the sheep, clips were insonated and the …

A Narrative Review Of Barriers To Utilization Of Surgical Risk Assessment Calculators, Jacob Lahti, Kaiya A. Noe, Abigail Veenstra, Sarah Gallitto, Victoria I. De Leon, Thomas C. Varkey, Nimit Agarwal

Annual Research Symposium

Over the last several decades, it has become the desire of surgical and medical teams to decrease risk levels involved for patients undergoing surgery. However, despite the advent of risk assessment calculators to help physicians obtain more accurate and objective judgements for postoperative complications, these tools are underutilized in standard clinical practices in comparison to other methods of risk assessment. This is likely due at least in part to certain barriers that decrease their functionality and ease of use. This review discusses the major barriers to the utilization of current risk calculators so as to allow for a better understanding …

Subtalar Dislocation With Isolated Talonavicular Dislocation – A Unique Case, Yaser J. Rahim, Naveen J. Pattisapu, Maxwell C. Alley

The Lahey Journal

Subtalar joint dislocations are infrequent injuries of the foot involving interruption of the articulations in the subtalar joint complex. These injuries involve dislocation of the talocalcaneal and talonavicular joints simultaneously with or without associated fractures. Subtalar joint dislocations are classified as medial or lateral, with medial dislocations occurring more commonly. Medial subtalar dislocations are generally not associated with other injuries whereas lateral subtalar dislocations are more frequently accompanied by fractures of talus, calcaneus or navicular. Prompt recognition of this dislocation and other injuries prevent negative sequelae associated with delayed treatment, and patients typically have a good outcome and return to …

Early Surgical Decompression For The Treatment Of Hourglass-Like Constriction Of The Posterior Interosseus Nerve, Nathan Redlich, Matan Ozery, Adam Haydel, Charles Cush, Rasheed Ahmad

School of Medicine Faculty Publications

Posterior interosseous nerve (PIN) syndrome refers to a rare compressive neuropathy of the PIN resulting in motor dysfunction of the forearm extensor compartment. Often, surgical exploration will reveal extrinsic structures that mechanically compress the nerve. Less frequently, PIN syndrome has been reported with a visible hourglass-like constriction and no identifiable causative adjacent structures. In our report, we describe an adolescent patient with PIN syndrome and associated hourglass-like constriction of the PIN. For diagnosis, we used physical examination, preoperative imaging, nerve studies, and intraoperative findings. To monitor recovery, we performed serial neurological examinations and documented patient-reported functional outcomes. The patient underwent …

Osteogenesis imperfecta (OI) is a multisystem disorder most often caused by pathogenic variants in genes that encode type I collagen. Type I collagen is abundant not only in bone but also in multiple tissues including skin, tendons, cornea, blood vessels, and heart. Thus, OI can be expected to affect cardiovascular system, and there are numerous reports of cardiovascular disease (CVD) in people with OI. However, there is no consensus on how CVD in OI should be assessed or managed. To fill this gap, a multidisciplinary group was convened to develop clinical guidance. The work included a systematic review of the …
