Severely Deformed Extraarticular Fractures Of The Scapula: A Review, Sean B. Kuehn

UNM Orthopaedic Research Journal

Nonoperative treatment of severely deformed fractures of the scapula was historically common. However, the findings of newer research have challenged the notion that conservatively managing these fractures results in the most successful outcomes. In an attempt to possibly reveal important indicators for surgical treatment, I reviewed studies on scapula fractures involving scapular anatomy; associated injuries; technological advances that have helped with fracture evaluation; and treatment outcomes between nonsurgical and surgical methods. Although a universally accepted classification scheme of scapula fractures does not exist, use of 3D reconstruction with computed tomography can help define the level and category of fracture deformity. …

Treatment Of Full Circumferential Segmental Bone Loss Of The Tibia Resulting From Acute Traumatic Injuries And Complications: A Review, Gregory C. Strohmeyer

UNM Orthopaedic Research Journal

Full circumferential segmental bone loss of the tibia presents a challenge to orthopaedic surgeons. These open fractures often involve extensive soft-tissue damage, which can contribute to poor long-term outcomes even if the tibia is successfully reconstructed. Although amputation was historically used to treat full circumferential segmental bone loss of the tibia because of the severity of the injury, the development of new reconstruction procedures has provided the option of limb salvage techniques. I reviewed studies on treatment of traumatic tibia bone loss, focusing particularly on full circumferential bone loss of greater than 3 cm. Treatment options included amputation, allograft replacement, …

Open Reduction And Internal Fixation For Treatment Of Proximal Humerus Fractures: A Review, Heather K. Woodin

UNM Orthopaedic Research Journal

Fractures of the proximal humerus are common in older patients, and the incidence of these fractures in the United States is expected to notably increase with the aging population. Nonoperative procedures have been preferred in elderly patients with stable fracture patterns to avoid complications associated with osteoporotic bone. However, more complex and unstable fracture patterns often necessitate operative techniques to allow for more anatomical healing. Although proximal humerus fractures have been thoroughly examined, systemized, and studied, no clear method to choosing an appropriate surgical treatment or candidate has been accepted. I reviewed the role of the following factors on successful …

Third Extensor Compartment Disruption And The Biomechanics Of Thumb Extension, Christina Salas, Drew K. Newhoff, Zainab Cheema, Allison A. Richards, Deana M. Mercer, Amanda K. Medoro, Ahmed M. Afifi, Moheb S. Moneim, John M. Veitch

UNM Orthopaedic Research Journal

Background: Procedures involving release of the third dorsal wrist compartment have been thought to transpose the extensor pollicis longus (EPL) tendon from its anatomical position. Few studies, however, have reported on the effects this might have on function and mechanics of the thumb. We analyzed the impacts of intact extensor retinaculum, release of the third dorsal compartment, and removal of Lister’s tubercle on thumb extension.

Methods: A total of 15 fresh-frozen cadaveric upper extremities (eight male, seven female; mean age, 52 years; range, 38-59 years) were used. For each specimen, three phases of testing were analyzed: the extensor retinaculum was …

Nonunion After Hybrid Plating With Locking And Nonlocking Screws In Radius And Ulna Shaft Fractures: Report Of Two Cases, Zainab Cheema, Nathan E. Huff, Deana M. Mercer

UNM Orthopaedic Research Journal

Conventional compression plating has been found effective in treating forearm diaphyseal fractures, providing stability as well as resistance to axial, torsional, and bending forces. Locked plating has provided stability without frictional force between the bone-plate interface, which may help preserve periosteal blood supply, and is useful in treating metaphyseal, comminuted, and osteoporotic fractures. Hybrid plating has been used in an attempt to combine the strengths of these two techniques; however, in the context of simple forearm diaphyseal fractures with healthy bone, its effectiveness is only theoretical. We describe two patients in whom open reduction and internal fixation with hybrid plating …

Isolated Traumatic Subscapularis Tear In A 12-Year-Old Male Gymnast: A Case Report, Katherine J. Gavin, Gehron P. Treme

UNM Orthopaedic Research Journal

Isolated avulsion fractures of the lesser tuberosity are rarely encountered in younger and older populations. However, because the tendon of the subscapularis insertion is stronger in skeletally immature individuals, isolated tears to the tendon occur more commonly in adults than children and adolescents. Most studies have been limited to case reports that mainly describe traumatic subscapularis tears in adolescent athlete-patients. We present a 12-year-old male gymnast who reported to our clinic with pain and weakness in the right shoulder at 2 months after the initial injury. We performed open repair with suture anchor fixation for treatment of an isolated subscapularis …

Carpal Tunnel Syndrome Associated With A Palmaris Profundus Tendon: A Case Report, Andrea B. Lese, Kristin M. Loker, Moheb S. Moneim

UNM Orthopaedic Research Journal

Carpal tunnel syndrome (CTS) is often found in adults and may be associated with rare anatomical abnormalities in the hand, such as the presence of a palmaris profundus tendon. Although the muscle was originally thought to be a variant of the palmaris longus muscle, some case studies have described both structures during operative treatment with open carpal tunnel release. We present a case of a 51-year-old woman who underwent open carpal tunnel release to treat CTS of the right hand. Preoperatively, results of electrodiagnostic tests and clinical examinations, respectively, were normal and equivocal. Intraoperatively, a palmaris profundus tendon was found …

Severe Ischemia Of The Finger After Use Of Compressive Self-Adherent Wrap: Report Of Two Cases, Andrea B. Lese, Elizabeth A. Mikola, Deana M. Mercer

UNM Orthopaedic Research Journal

Use of Coban compressive self-adherent wraps (3M, St Paul, MN) has been found helpful in treating various conditions and injuries of the extremities, including lymphedema, edema in burned hands, and sprains or strains. However, the availability and easy application of the wrap have resulted in its common usage with or without adequate instructions. We report two cases in which severe pain and ischemia developed after this bandage was circumferentially applied to a finger to stop bleeding from a simple laceration. One patient required amputation at the level of the proximal interphalangeal joint; the other had resolution of venous congestion symptoms …

Surgical Treatment Of Chronic Dislocation Of A Posterior Tibial Tendon In A Collegiate Athlete: A Case Report, Tony G. Pedri, Richard A. Miller

UNM Orthopaedic Research Journal

Traumatic dislocation of the posterior tibial tendon (PTT) is a rare and often misdiagnosed injury. The limited number of cases, ambiguous results of initial imaging studies, and presence of symptoms similar to medial ankle sprains can contribute to unsuccessful long-term treatment. Current studies, although limited, report high rates of failure in nonoperative compared with operative treatment. We describe a 21-year-old male baseball player who experienced pain and mild swelling in his ankle after falling while running at full speed. After 5 months of continuous pain in the medial ankle, the patient was referred to our clinic and underwent suture anchor …

Unicameral Bone Cyst Of The Pelvis In A 13-Yearold Boy Treated With Cannulated Screw Decompression After Open Curettage And Grafting: A Case Report, Reilly J. Kuehn, David H. Chafey

UNM Orthopaedic Research Journal

Although studied for more than a century, the cause of unicameral bone cyst (UBC) remains uncertain. UBC of the pelvis in younger patients has been particularly problematic because its rarity often results in misdiagnosis and improper treatment. Surgical treatment has typically involved percutaneous or open curettage and bone grafting; however, some studies have described the use of a continuous decompression device to address high recurrence rates of the lesion. We present a 13-year-old male patient in whom, after two unsuccessful operations, open curettage and grafting and insertion of a cannulated screw led to resolution of pain caused by a large, …

Scaphoid Stress Fracture In A 65-Year-Old Man With Low Bone Mineral Density: A Case Report, Dean W. Smith

UNM Orthopaedic Research Journal

Although commonly reported in women and less commonly in younger athletes, no studies have reported stress fractures of the scaphoid in older, sedentary men. Because of its rarity, osteoporosis in older men is often unrecognized and only diagnosed after the fracture. I describe a previously sedentary 65-year-old man who presented to my clinic with pain in the right wrist after his first day of intense physical activity and underwent 8 weeks of splinting and bracing for treatment of a fracture of the waist of the scaphoid. Ten weeks after the pain began, a computed tomography image revealed healing of the …

An Analysis Of The Effects Of The Carbohydrate Intake And Hydration On Feeling Of Exertion Throughout A Marathon, Kristine M. Baumann, Kaitlyn Proulx

All Electronic Theses and Dissertations

The popularity of marathon running has grown exponentially since the 1970s (Noakes, 2003). This major gain in popularity has led to an increased interest in hydration and nutrition for marathon runners (Tucker et al 2009). The effects of dietary factors such as carbohydrates (CHO) and water on endurance has been extensively studied related to performance, but few studies have examined nutrition’s effect on feelings of exertion. The current study aimed to determine how the in-race nutrition and hydration habits of marathon runners affect their feelings of exertion throughout a 26.2-mile race. Individuals running Grandma’s Marathon in Duluth, MN on June …

The Effect Of Education On Folic Acid In Women On Childbearing Age And Low Socioeconomic Status, Macey I. Bentley, Anna R. Goetsch, Courtney L. Perpich

All Electronic Theses and Dissertations

The purpose of this study was to investigate the effect of education to women of lower socioeconomic status about the importance of folic acid use before and during pregnancy. Previous research has shown the significance of folic acid in preventing neural tube defects; however, research has shown that women of lower socioeconomic status are not equipped with proper education regarding folic acid usage periconceptionally. An educational session was provided to three women’s shelters regarding folic acid, and questionnaires were used to gauge knowledge on folic acid before and after the sessions. The statistical analysis was consistent with our hypothesis in …

Concussion Education In High School Athletes, Nathan A. Birno, Larson Davick, Kyle Oostra

All Electronic Theses and Dissertations

This paper examines concussion education in high school athletes. Specifically, it examines how educationally beneficial a concussion presentation is for high school athletes. The study examined eighteen-year-old participants from two Minnesota high schools participating in Minnesota State High School League (MSHSL) sanctioned spring sports. A presentation on concussion definitions, signs/symptoms, and adverse effects was presented to the participants. A pre and posttest questionnaire was used to evaluate participants’ baseline knowledge on concussion related topics and their knowledge gained after hearing the presentation. Data was analyzed via a comparison of the mean score differences using a paired t-test of within group …

Oncology Providers’ Opinions On Preventative Recommendations For Patients With Brca1 Or Brca2 Breast Cancer Mutations, Rebecca L. Crissman, Kathleen Dunsmore

All Electronic Theses and Dissertations

BRCA1 and BRCA2 gene mutations have been identified as increasing an individual’s risk for developing breast cancer. Genetic testing for these genes has become increasingly more common. However, once genetic testing has established that an individual has either a BRCA1 or BRCA2 mutation, there is no set guideline for preventative measures. The purpose of this study is to gain the opinions of oncology healthcare providers on their recommendation for preventative treatment in women who have been diagnosed with the mutation at varying ages. A web-based survey was emailed to oncology healthcare providers from Minnesota Oncology in Minnesota and Allegheny Health …

Attitudes And Utilization Of Tissue Plasminogen Activator Involving Telemedicine, Karin K. Filip, Brittany R. Kelly, Stacy M. Underhill

All Electronic Theses and Dissertations

Tissue plasminogen activator (tPA) is used to treat acute ischemic stroke and is widely accepted as standard practice in the medical community. Literature shows that providers are hesitant to use this therapy due to the associated risks. Supporting literature shows that tPA is highly effective if administered within a three hour window, when adhering to strict protocols and guidelines for patient qualification. Telestroke programs have been shown to improve the time from stroke onset to administration of tPA by allowing a neurologist to be present during the decision making process. The aim of the study was to examine attitudes of …

Comparison Of Oral And Printed Health Literacy Tools In Hypertension Education For Low-Income Patients, Andrew D. Forsgren, Annie Heggestad, Charles Ruegemer

All Electronic Theses and Dissertations

Hypertension is a prevalent health concern in today’s society, especially among individuals of low-income economic status. An increased risk for heart disease has long been correlated to hypertension, and this risk increases further as the population ages. Patient education is crucial for prevention and management of diseases such as hypertension; therefore it is necessary to develop effective education tools. This is particularly true among high-risk groups such as low-income populations. This study compared the efficacy of printed educational materials versus orally presented educational materials in terms of improving patient knowledge regarding hypertension. Subjects were randomly assigned to either the printed …

Chemically Self-Assembled Antibody Nanorings: A Novel Approach To Bispecific Design For Cancer Therapeutics, Kari A. Gabrielse

All Electronic Theses and Dissertations

Targeted antibody therapeutics are currently being developed for treatment of a wide variety of cancers. By extending the scope of targeted antibody therapeutics into a bispecific design, it has been shown that simultaneous targeting of the CD3 T cell receptor and cancer cell receptors is possible. While great success has been achieved with the use of bispecific agents, many of these agents are genetically fused antibody fragments that can only target one type of cancerous receptor. Here we describe a simple and straightforward method of spontaneously assembling bispecific antibody therapeutics. Using fusion proteins consisting of two dihydrofolate reductase proteins and …

Health Disparities On American Indian Reservations: Can Mid-Level Practitioners Make A Difference?, David Evard Johnston

Efforts have been made through the Indian Health Service (IHS) to improve the AI/AN state of health, but healthcare disparities remain. Purpose: The purpose of this study was to assist in identifying options in reducing healthcare disparities on American Indian reservations in South Dakota. The need for recruitment of additional physicians and mid-level practitioners (also known as mid-level providers or advanced practice providers) was assessed, as well as the potential for mid-level practitioners to meet that need. Methods: A …

Prevalence Of Non-Conventional And Folk Medicine Usage Among Hmong In St. Paul, Minnesota, Matthew T. Vang

All Electronic Theses and Dissertations

Hmong Americans have been identified to utilize various modes of medicine including: folk/herbal remedies, spiritual/shamanistic rituals, and adapted treatments from countries like Thailand or Laos. However, there is a lack of studies that measured the prevalence of these medications among the Hmong community in Saint Paul, Minnesota. A questionnaire was distributed at a Saint Paul, Minnesota Hmong market to explore the prevalence of Hmong medicine usage. Demographical information was also collected to help determine any relationships that might exist between certain socio-cultural factors and Hmong medicine usage. The study had a total of 54 participants. Of the 54 participants, twenty-eight …

Inhibitory Behavioral Control: A Stochastic Dynamic Causal Modeling Study Comparing Cocaine Dependent Subjects And Controls, Liangsuo Ma, Joel L. Steinberg, Kathryn A. Cunningham, Scott D. Lane, James M. Bjork, Harshini Neelakantan, Amanda E. Price, Ponnada A. Narayana, Thomas R. Kosten, Antoine Bechara, F. Gerard Moeller

Radiology Publications

Cocaine dependence is associated with increased impulsivity in humans. Both cocaine dependence and impulsive behavior are under the regulatory control of cortico-striatal networks. One behavioral laboratory measure of impulsivity is response inhibition (ability to withhold a prepotent response) in which altered patterns of regional brain activation during executive tasks in service of normal performance are frequently found in cocaine dependent (CD) subjects studied with functional magnetic resonance imaging (fMRI). However, little is known about aberrations in specific directional neuronal connectivity in CD subjects. The present study employed fMRI-based dynamic causal modeling (DCM) to study the effective (directional) neuronal connectivity associated …

Imitation By Combination: Preschool Age Children Evidence Summative Imitation In A Novel Problem-Solving Task., Francys Subiaul, Edward Krajkowski, Elizabeth E Price, Alexander Etz

Pediatrics Faculty Publications

Children are exceptional, even 'super,' imitators but comparatively poor independent problem-solvers or innovators. Yet, imitation and innovation are both necessary components of cumulative cultural evolution. Here, we explored the relationship between imitation and innovation by assessing children's ability to generate a solution to a novel problem by imitating two different action sequences demonstrated by two different models, an example of imitation by combination, which we refer to as "summative imitation." Children (N = 181) from 3 to 5 years of age and across three experiments were tested in a baseline condition or in one of six demonstration conditions, varying in …

Principles Of Using Cold Atmospheric Plasma Stimulated Media For Cancer Treatment, Dayun Yan, Annie Talbot, Niki Nourmohammadi, Xiaoqian Cheng, Jerome Canady, Jonathan H. Sherman, Michael Keidar

Neurological Surgery Faculty Publications

To date, the significant anti-cancer capacity of cold atmospheric plasma (CAP) on dozens of cancer cell lines has been demonstrated in vitro and in mice models. Conventionally, CAP was directly applied to irradiate cancer cells or tumor tissue. Over past three years, the CAP irradiated media was also found to kill cancer cells as effectively as the direct CAP treatment. As a novel strategy, using the CAP stimulated (CAPs) media has become a promising anti-cancer tool. In this study, we demonstrated several principles to optimize the anti-cancer capacity of the CAPs media on glioblastoma cells and breast cancer cells. Specifically, …
