A Mssic Study Reveals Non- Modifiable Risk Factors Were Associated With Post-Operative Hematoma Following Acdf, Richard Easton, Matthew Lipphardt, Matthew Easton, Nicholas Papakonstantinou, Lonni Schultz, Hsueh-Han Yeh, Cecile Pestano

Posters

Introduction

Post-operative hematoma (POH) following anterior cervical discectomy (ACDF) is uncommon . Although rare, POH is recognized as a potentially catastrophic post-operative complication . There is limited information as to who is vulnerable . From a large database, the authors sought to identify common modifiable and non-modifiable risk factors for developing POH and its associated clinical outcomes.

Materials and Methods

The Michigan Spine Surgery Improvement Collaborative (MSSIC) is a statewide quality improvement initiative . ACDF cases in MSSIC registry from 2014-2018 were identified . Patients who developed POH (POH) were compared to those who did not (non-POH) . Chi-square and …

Imaging-Based Modules For Musculoskeletal Anatomy & Pathology In Preclinical Medical Education, Ameen Suhrawardy, Tarek Almsaddi, Sarah Fried, Sayf Al-Katib, Drew Moore, Malli Barremkala

Posters

Many medical students report a lack of adequate orthopedic and musculoskeletal (MSK) teaching in the preclinical medical curriculum. As gross anatomy is emphasized in pre-clinical education, students may feel a disconnect from clinical anatomy proficiency. This project assesses the efficacy of a preclinical image-based module to teach MSK anatomy and pathology concepts to preclinical medical students.

The Routine Use And Cost Analysis Of Acid-Fast Bacilli And Fungal Cultures In Foot And Ankle Surgery: A Retrospective Study, Margaret Bohr, Robert Dean, Zein El-Zein, Megan Audet, Paul Fortin, Zachary Vaupel

Posters

Infection is a significant complication seen in orthopaedic surgery. In such cases, samples are sent to be cultured for aerobes, anaerobes, acid-fast bacilli (AFB) and fungi. AFB and fungi are generally slow-growing, difficult to culture, and rarely the pathogen, whereas aerobic and anaerobic cultures are routinely positive and guide antibiotic treatment. The goal of this study is to evaluate the value of routinely ordering AFB and fungal cultures in the setting of foot and ankle surgery.

Assessment Of Radiographic Features In Predicting Complete Quadriceps And Complete Patellar Tendon Ruptures In The Pre-Operative Setting, Mitchell Pfennig, Matthew Astolfi, Christopher Vasileff, Betina Hinckel

Posters

Acute patellar tendon or quadriceps tendon rupture is a severely debilitating injury resulting in complete loss of the knee extensor mechanism. Early diagnosis and prompt surgical repair are preferential in order to achieve good functional outcomes. In the setting of trauma and knee pain, plain film radiographs of the knee are obtained to rule out fractures. Patellar and quadriceps tendon rupture is primarily a clinical diagnosis but can benefit from additional imaging to differentiate between a partial and complete tear when there is uncertainty. Our goal is to assess the reliability and reproducibility of radiographic features in a population with …

Trends & Outcomes In Shoulder Arthroplasty: Comparing Anatomic, Reverse, & Hemiarthroplasty, James Gannon, Anthony Arveschoug, Leonardo M. Cavinatto

Posters

The field of shoulder replacement has evolved greatly since the inception of the reverse shoulder arthroplasty (RTSA) in 2004. With yearly gains of 32%, the RTSA now encompasses the largest portion of shoulder arthroplasty procedures. In contrast, the anatomic total shoulder arthroplasty (ATSA) and hemiarthroplasty (HA) have steadied or decreased. Surgical outcomes between these three procedures are mixed however. The purpose of this study was to characterize trends and outcomes between the RTSA, ATSA, and HA at a large-volume, single-institution center

Surveillance Of Dual-Mobility Hip Systems: Damage Mode And Clinical Data Analysis, Camilla Cascardo, Conner D. Ahlgren, Michael J. Maxwell, Tyler Vovos, Mark Karadsheh, Drew Moore

Posters

Hip instability following total hip arthroplasty (THA) is a prominent indication for revision surgery. Dual mobility (DM) implants are designed to increase stability, and trending use makes characterizing in vivo damage and clinical failure modes important. This study expounds upon micro- and macroscopic damage mode findings of Lombardo et al., including novel screw ring damage using an updated retrieval registry.

Phenotype Characterization Of Genetic Murine Mouse Models Of Developmental Dysplasia Of The Hip (Ddh), Stephanie Mrowczynski, Kevin Baker, Michael Newton

Posters

Developmental dysplasia of the hip (DDH) is a congenital hip alteration that changes the “ball in socket” movement of the leg inside the pelvis. Genome-wide association studies have identified CX3CR1 polymorphisms associated with increased risk of Developmental Dysplasia of the Hip. Mouse models of CX3CR1 knock-out (KO) mice show unilateral, bony discrepancies between the femur head and acetabulum in comparison to wild-type (WT) mice, as well as gait impairment similar to that of humans with osteoarthritis (which develops in DDH patients later in life). The primary goal of this project is to assess joint congruity in a CX3CR1 KO model …

Acute Post-Operative Pain Following Anterior Cruciate Ligament Reconstruction: A Comparison Of Patellar Tendon Vs Hamstring Autograft, Dustin J Randall, Denise Koueiter, Brandon Luczak, Kyle Anderson

Posters

INTRODUCTION
Choosing between a bone-patellar tendon-bone (BTB) or hamstring tendon (HS) graft for primary anterior cruciate ligament (ACL) reconstruction has long been a topic of debate and discrepancy in orthopaedic literature, with many factors contributing to the decision process. The purpose of this study is to analyze acute post-operative pain scores of patients who underwent ACL reconstruction and compare the results between BTB autograft and the HS autograft techniques.

Defining Functional Shoulder Range Of Motion In Middle-Aged To Elderly Populations To Guide Shoulder Surgical Treatment, Tyler Sargent, Justin Smith, Christie Smith, John Krauss, Michelle Jankowski, J Michael Wiater

Posters

INTRODUCTION
Functional range of motion (ROM) is defined as the minimal required mobility of a joint to complete activities of daily living (ADL). Defining functional ROM will allow surgeons to decide which aging patients would benefit from surgical intervention aimed at improving shoulder functionality.

Applying The Periprosthetic Joint Infection Consensus Definition To Ankle Implant-Associated And Infection-Suspected Procedures To Assess Diagnosis, Jackson Harley, Erin Baker, Corinn K. Gehrke, David Ciufo, Zachary M. Vaupel, Paul T. Fortin

Posters

INTRODUCTION
Periprosthetic joint infection (PJI) affects 2-3% of all total joint replacement cases. In 10-30% of these cases, the organism is unidentifiable, which may impact treatment planning and outcomes. In this study, suspected periprosthetic infections of foot and ankle procedures treated by four foot and ankle-trained orthopedic surgeons were retrospectively reviewed to determine culture status and applicability of the 2018 International Consensus Meeting on Orthopedic Infections (ICM) classification system.

Evaluating Taper Junction Fretting And Corrosion In Reverse Total Shoulder Arthroplasty, Ian R. Penvose, Erin A. Baker, J. Michael Wiater, Corinn K. Gehrke, Jonathan O Wright, Omar N. Khatib, Brett P Wiater

Posters

INTRODUCTION
Taper junction fretting and corrosion (F&C) has been identified in total hip arthroplasty (THA) as an implant failure mode. Studies have reported taper F&C in in anatomic total shoulder arthroplasty (ATSA) implants, but limited literature has described comparable analyses in reverse shoulder arthroplasty (RTSA) implants. In this study, taper junction F&C in retrieved RTSA implants was assessed and analyzed.
