Faculty, Staff and Student Publications

Background: Differences in rotational range of motion (ROM) compared to humeral retrotorsion (HRT)-corrected rotational ROM exist in healthy baseball athletes, but it is unclear whether these differences exist in a pathological population.

Purpose/hypothesis: The purpose of this study was to determine if there are disparities between objectively measured differences in ROM and HRT-corrected deficits in injured baseball players. It was hypothesized that disparities would exist between (1) the side-to-side difference in glenohumeral external rotation (GER) and the HRT-corrected glenohumeral external rotation deficit (GERD) and (2) the side-to-side difference in glenohumeral internal rotation (GIR) and the HRT-corrected glenohumeral internal rotation deficit …

Structure And Function Are Not The Same: The Case For Restoring Mechanoreceptor Continuity Following Anterior Cruciate Ligament Injury, Jillian E Beveridge, Payam Zandiyeh, Brett D Owens, Ata M Kiapour, Braden C Fleming

Faculty, Staff and Student Publications

Anterior cruciate ligament (ACL) injury, particularly in increasingly young and active adolescents, continues to pose a clinical challenge with re-injury rates reported as high as 30%. Evidence also suggests that current standard-of-care ACL reconstruction (ACLR) does not mitigate post-traumatic osteoarthritis (PTOA) risk. Bridge- enhanced ACL restoration (BEAR) is a recently developed and tested ACL surgery that promotes primary healing of the native ACL with excellent early results. BEAR has shown to reduce signs of early PTOA compared to ACLR in an animal model. Here, we describe a theoretical framework related to re-innervation that can clarify why the outcomes of ACLR …

Multiple myeloma (MM) is a hematologic malignancy characterized by uncontrolled proliferation of plasma cells in the bone marrow. MM patients with aggressive progression have poor survival, emphasizing the urgent need for identifying new therapeutic targets. Here, we show that the leukocyte immunoglobulin-like receptor B1 (LILRB1), a transmembrane receptor conducting negative immune response, is a top-ranked gene associated with poor prognosis in MM patients. LILRB1 deficiency inhibits MM progression in vivo by enhancing the ferroptosis of MM cells. Mechanistic studies reveal that LILRB1 forms a complex with the low-density lipoprotein receptor (LDLR) and LDLR adapter protein 1 (LDLRAP1) to facilitate LDL/cholesterol …

Vertebral Hu Value And The Pectoral Muscle Index Based On Chest Ct Can Be Used To Opportunistically Screen For Osteoporosis, Xiong-Yi Wang, Sheng Pan, Wei-Feng Liu, Yi-Ke Wang, Si-Min Yun, You-Jia Xu

Faculty, Staff and Student Publications

BACKGROUND: Existing studies have shown that computed tomography (CT) attenuation and skeletal muscle tissue are strongly associated with osteoporosis; however, few studies have examined whether vertebral HU values and the pectoral muscle index (PMI) measured at the level of the 4th thoracic vertebra (T4) are strongly associated with bone mineral density (BMD). In this study, we demonstrate that vertebral HU values and the PMI based on chest CT can be used to opportunistically screen for osteoporosis and reduce fracture risk through prompt treatment.

METHODS: We retrospectively evaluated 1000 patients who underwent chest CT and DXA scans from August 2020-2022. The …

Spinal metastases can result in severe neurologic compromise and decreased overall survival. Despite treatment advances, local disease progression is frequent, highlighting the need for novel therapies. Tumor treating fields (TTFields) impair tumor cell replication and are influenced by properties of surrounding tissue. We hypothesized that bone's dielectric properties will enhance TTFields-mediated suppression of tumor growth in spinal metastasis models. Computational modeling of TTFields intensity was performed following surgical resection of a spinal metastasis and demonstrated enhanced TTFields intensity within the resected vertebral body. Additionally, luciferase-tagged human KRIB osteosarcoma and A549 lung adenocarcinoma cell lines were cultured in demineralized bone grafts …

Anterior Cruciate Ligament Hybrid Remnant Preservation Reconstruction Demonstrates Similar Outcomes As Traditional Reconstruction After 6 Months: A Randomized Control Trial, Joshua P. Castle, Eleftherios L. Halkias, Brittaney Pratt, Ashley Frei, Matthew A. Gasparro, Vasilios Moutzouros

Medical Student Research Symposium

Background

The anterior cruciate ligament (ACL) is often debrided during reconstruction (ACLR) to improve visualization. However, remnant ACL tissue contains nerve fibers and including remnant tissue in ACLR could provide benefit. Therefore, a technique was developed that preserves the tibial remnant and incorporates it into ACLR: Hybrid Remnant Preservation Reconstruction (HRPR) ACLR. This study compares HRPR-ACLR to traditional reconstruction by comparing patient reported outcomes and complications.

Methods

Patients presenting to one surgeon's clinic with an ACL injury are screened. Exclusion criteria are patient age<14 years, multi-ligament injury, chronic tears, and revision ACLR. Patients are consented and randomized to HRPR or traditional ACLR. Demographics, patient-reported outcomes, range of motion (ROM) and complications were collected.

Results

Thirty-three patients were included, 20 HRPR and 13 controls. No demographic differences were noted. PROMIS-PF, …

Osteosarcoma(OS) is a highly aggressive bone cancer for which treatment has remained essentially unchanged for decades. Although OS is characterized by extensive genomic heterogeneity and instability, RB1 and TP53 have been shown to be the most commonly inactivated tumor suppressors in OS. We previously generated a mouse model with a double knockout (DKO) of Rb1 and Trp53 within cells of the osteoblastic lineage, which largely recapitulates human OS with nearly complete penetrance. SKP2 is a repression target of pRb and serves as a substrate recruiting subunit of the SCFSKP2 complex. In addition, SKP2 plays a central role in regulating the …

Belzutifan, Hif-2Α Inhibitor, And Clear Cell Renal Cell Carcinoma With Somatic Von-Hippel-Lindau Loss-Of-Function Mutation, Kok Hoe Chan, Ningjing Li, Ran Lador, Mark Amsbaugh, Anneliese Gonzalez, Putao Cen

Faculty, Staff and Student Publications

The Von-Hippel-Lindau (VHL) gene, acting as a tumor suppressor, plays a crucial role in the tumorigenesis of clear cell renal cell carcinoma (ccRCC). Approximately 90% of individuals with advanced ccRCC exhibit somatic mutations in the VHL gene. Belzutifan, orally administered small-molecule inhibitor of hypoxia-induced factor-2α, has demonstrated promising efficacy in solid tumors associated with germline loss-of-function mutations in VHL, including ccRCC. However, its impact on cases with somatic or sporadic VHL mutations remains unclear. Here, we present 2 cases where belzutifan monotherapy was employed in patients with advanced ccRCC and somatic loss-of-function mutations in VHL. Both patients exhibited a swift …

The Impact Of Local Physiology On The Corrosion Of Orthopedic Alloys, Madison Nicole Brown

Theses and Dissertations (ETD)

Introduction. Total knee arthroplasty (TKA) is used in the treatment of end-stage osteoarthritis of the knee. It is one of the most common elective surgeries performed with predictions expecting significant increases in the number of procedures performed over the next decade. However, the patient satisfaction rate after TKA is as low as 80%. Cobalt-chromium-molybdenum (CoCrMo) is regularly used for TKA protheses due to the alloy’s mechanical strength, biocompatibility, and corrosion resistance. The corrosion resistance of this alloy relies on a passive oxide layer. This oxide layer can be impacted by phagocytic cells which can leave pits and craters on implant …

Biomechanical Outcomes Of Distinct Tka Surgical Alignments And Implant Designs, Alexis Kathleen Nelson-Tranum

Theses and Dissertations (ETD)

Introduction. Total knee arthroplasty (TKA) has advanced over the past two decades from traditional post-operative neutral alignment methods with an overall goal of implant longevity to ones that are more personalized to better replicate individual native knee kinematics. Personalizing TKA knee kinematics to better replicate a patient’s native knee kinematics has evolved in response to a reported 20% dissatisfaction by patients with their TKA. These personalization advancements include innovations in surgical alignment techniques include the kinematic alignment (KA) and joint line obliquity (JLO) restoration, in contrast to the mechanical alignment (MA) technique that places everyone into the same mold. Additionally, …

The Hidden Impact Of Orthopedic Surgeries: Examining The Psychological Consequences, Emily R Erwin, Keisha S Ray, Shuyang Han

Faculty, Staff and Student Publications

Orthopedic surgery is commonly considered "quality of life care," as most orthopedic procedures have been shown to provide excellent pain relief and successful surgical outcomes for patients. Although orthopedic surgeries continue to improve patients' functional outcomes through modern surgical techniques and preoperative psychological screening, variation in patient function persists in current studies. Sub-optimal function in patients has been shown to be associated with emotional health burdens, such as anxiety and depression. Previous research has found that preoperative psychological conditions could negatively affect patients' functional outcomes. However, these studies were limited in that they did not examine novel psychological repercussions in …

Femoral Neck Fracture Management In The Young Patient: A Case Review, Luis Berrios, Kevin J. Orellana, Michael Lago, Frank Gerold

Research Colloquium

Introduction:The optimal management of femoral neck fractures in the young patient remains controversial. Although there are universally accepted principles, there remains some variability in the optimal timing of surgery and method of fixation. In general, surgery should be performed on an urgent or emergent basis when feasible to decrease peri-operative complications, length of stay, and most importantly the ultimate likelihood of avascular necrosis. However, it is important to note that the preference toward a specific method of fixation remains heterogeneous among orthopedic surgeons.(1)

The purpose of this study is to present our preferred technique for treatment of displaced femoral …

A Review Of The Role Of Tendon Stem Cells In Tendon-Bone Regeneration, Junjie Chen, Chuanfeng Jiang, Lu Yin, Yingqi Liu, Yue He, Sen Li, Huarui Shen

Faculty, Staff and Student Publications

Tendon-bone injuries are a prevalent health concern associated with sports and other physically demanding activities. These injuries have a limited innate healing ability, often leading to the formation of scar tissue rather than the regeneration of healthy tendon tissue. This scar tissue results from excessive fibrosis during the early healing process and often leads to reduced tendon function and an increased risk of reinjury. Traditionally, surgical reconstruction has been the primary treatment for tendon-bone injuries. However, restoring the natural structure and mechanical properties of tendons after surgical reconstruction presents a considerable challenge. Recently, the potential of stem cell therapy has …
