STUDY DESIGN: Retrospective cohort study.

PURPOSE: Our goal was to determine which radiographic images are most essential for degenerative spondylolisthesis (DS) classification and instability detection.

OVERVIEW OF LITERATURE: The heterogeneity in DS requires multiple imaging views to evaluate vertebral translation, disc space, slip angle, and instability. However, there are several restrictions on frequently used imaging perspectives such as flexion-extension and upright radiography.

METHODS: We assessed baseline neutral upright, standing flexion, seated lateral radiographs, and magnetic resonance imaging (MRI) for patients identified with spondylolisthesis from January 2021 to May 2022 by a single spine surgeon. DS was classified by Meyerding and …

Long-Term Bilateral Neuromuscular Function And Knee Osteoarthritis After Anterior Cruciate Ligament Reconstruction, Payam Zandiyeh, Lauren R Parola, Meggin Q Costa, Madalyn J Hague, Janine Molino, Braden C Fleming, Jillian E Beveridge

Faculty, Staff and Student Publications

Neuromuscular function is thought to contribute to posttraumatic osteoarthritis (PTOA) risk in anterior cruciate ligament (ACL)-reconstructed (ACLR) patients, but sensitive and easy-to-use tools are needed to discern whether complex muscle activation strategies are beneficial or maladaptive. Using an electromyography (EMG) signal analysis technique coupled with a machine learning approach, we sought to: (1) identify whether ACLR muscle activity patterns differed from those of healthy controls, and (2) explore which combination of patient outcome measures (thigh muscle girth, knee laxity, hop distance, and activity level) predicted the extent of osteoarthritic changes via magnetic resonance imaging (MRI) in ACLR patients. Eleven ACLR …

Enough Is Enough: Salvage Procedures In Severe Periprosthetic Joint Infection, Yves Gramlich, Javad Parvizi

Rothman Institute Papers

Background

In severe cases of periprosthetic joint infection involving negative host-dependent factors, individual-based decisions between a curative therapy vs. salvage procedure are necessary. We aimed to review salvage procedures in severe periprosthetic joint infection cases, where a gold standard of a curative two-stage exchange can no longer be achieved. The options of knee arthrodesis, amputation, persistent fistula (stable drainage), or a debridement, antibiotics, and implant retention procedure in late-onset cases are discussed, including lifelong antibiotic suppression alone.

Methods

We focused on known salvage procedures for severe periprosthetic joint infection of the hip and knee, such as amputation, arthrodesis, antibiotic …

Republication Of "Uses Of Braces And Orthotics For Conservative Management Of Foot And Ankle Disorders"., Osama Elattar, Tyler Smith, Adam Ferguson, Daniel Farber, Keith Wapner

Orthopedic Surgery Resident Research

Nonsurgical management is almost always considered the first-line treatment for the vast majority of foot and ankle pathologies. Foot orthoses, shoe modifications, and therapeutic footwear are considered essential tools for successful conservative management of different foot and ankle disorders. Orthopedic foot and ankle surgeons should have a meticulous understanding of the lower extremity biomechanics as well as the pathoanatomy and the sequelae of diseases affecting the foot and/or ankle. This is essential to the understanding of the desired effects of the different inserts, orthotics, shoe modifications, or braces that may be prescribed for these conditions. In this article, we will …

Multiple Sterile Withdrawals From Iohexol Bottles Does Not Increase Contamination Risk, Caroline Purtill, Manraj Dhesi, Daniel Haber, Nicholas D'Antonio, Noreen J. Hickok, Jeremy I. Simon

Department of Orthopaedic Surgery Faculty Papers

BACKGROUND: There is a global shortage of iohexol contrast media, commonly used in epidural injections, as a result of lockdown and decreased production due to COVID-19. Iohexol bottles are designated for single use, which, depending on the vials available, often leads to wasting up to 95% of this limited resource. However, avoiding multiple withdrawals may be unnecessary if withdrawing multiple times using sterile technique does not increase the risk for contamination.

OBJECTIVES: The purpose of our study is to determine whether multiple withdrawals from iohexol injection bottles using a sterile technique poses a greater risk of introducing contaminants than a …

Primary Retrograde Tibiotalocalcaneal Nailing In An Elderly Osteoporotic Patient With Ankle Fracture: A Case Report., Nolan P Schmitz, Daniel R Gaines, Jignesh N Patel

Surgery Articles

INTRODUCTION: Ankle fractures are a common orthopedic injury traditionally treated with open reduction and internal fixation or conservative management. One complication introduced with open reduction and internal fixation is the requirement for non or partial weight bearing in the post-operative period. This requirement poses a unique challenge for patients who may not comply with these weight-bearing restrictions. This case is the first known article that specifically illustrates the validity and effectiveness of retrograde tibiotalocalcaneal (TTC) nailing for patients who are unlikely to follow weight-bearing restrictions.

CASE REPORT: An 83-year-old Caucasian female with idiopathic mild mental retardation and Alzheimer's presented with …

Diagnosis Of Periprosthetic Joint Infection: The Utility Of Biomarkers In 2023, Mehmet Kursat Yilmaz, Ahmad Abbaszadeh, Saad Tarabichi, Ibrahim Azboy, Javad Parvizi

Rothman Institute Papers

Periprosthetic joint infection (PJI) is a rare yet devastating complication following total joint arthroplasty (TJA). Early and accurate diagnosis of PJI is paramount in order to maximize the chances of successful treatment. However, we are yet to identify a single “gold standard” test for the diagnosis of PJI. As a result, the diagnosis of PJI is often challenging. Currently, the 2018 ICM definition of PJI is the only validated diagnostic criteria available. This article will review the importance of serum and synovial biomarkers in the diagnosis of PJI. In addition, it will provide a brief overview of the emerging modalities …

Principles Of Arthroscopic - Assisted Open Reduction Internal Fixation In The Management Of Displaced Articular Fractures, Nathan Sherman, Matthew Miller, Michael D. Feldman

Western Journal of Orthopaedics

The primary objective of fracture fixation is to obtain anatomic reduction with stable fixation while minimizing damage to the surrounding structures. Displaced articular fractures represent a surgical challenge, but anatomic alignment with restoration of the articular surface is the gold standard of management. Using open techniques, intra-articular visualization can require large dissections and added soft-tissue insult. However, arthroscopic-assisted open reduction internal fixation (AAORIF) may represent a less invasive means of articular fracture management in appropriate patients with select fractures. The general principles of AAORIF are modified from basic arthroscopic principles, including positioning, portal placement, fluid management, visualization, soft-tissue management, and …

Let’S Focus On The Fibrosis: Targeting Ccn2 In Dupuytren’S Disease, Alex G. Lambi, Ryan Dahlberg, Tomas Holy, Joseph T. Tarr, Deana Mercer, Steven N. Popoff, Mary F. Barbe

Western Journal of Orthopaedics

Dupuytren’s disease is a progressive, benign fibroproliferative disorder of the hands that can lead to debilitating hand contractures. Once symptomatic, treatment involves either surgical intervention, specifically fasciectomy or percutaneous needle aponeurotomy, or enzymatic degradation with clostridial collagenase. Currently, collagenase is the only pharmacotherapy that has been approved for the treatment of Dupuytren’s contracture. There is a need for a pharmacotherapeutic that can be administered to limit disease progression and prevent recurrence after treatment. Targeting the underlying fibrotic pathophysiology is critical. The authors propose a novel target to be considered in Dupuytren’s disease – cell communication network factor 2/connective tissue growth …

Complex Lisfranc Injury In A Professional Bull Rider, Elizabeth Eichman, Stephan Sierra, Matthew Ferguson

Western Journal of Orthopaedics

American bull riding is one of the most dangerous sports in the world, with a high prevalence of injury. Due to the high-velocity trauma that is common in this sport, injuries occur frequently and are often classified as severe despite the use of protective equipment. While Lisfranc fracture-dislocations are somewhat common in elite athletes, open Lisfranc fractures are much less common. Consequently, there are little data concerning recovery and return to sport. This case demonstrates an uncommon presentation of open Lisfranc fracture dislocation and first metatarsophalangeal dislocation in a professional bull rider who was able to return to sport at …

Perioperative Nutritional Considerations In Orthopaedic Surgery: A Review Of The Literature, William Curtis, Timothy Choi, Aamir Ahmad, Christopher Shultz

Western Journal of Orthopaedics

Macronutrients and micronutrients play an essential role in the surgical process, beginning in preoperative preparation and extending well into postoperative recovery. It is important that orthopaedic surgeons and their patients understand the physiological impact of the surgical stress response and the ways in which adequate perioperative nutrition can help combat its negative effects. Throughout this article, the authors discuss the important roles of macronutrients, such as carbohydrates, protein, and fatty acids, and that of micronutrients, including zinc and vitamins C, D, A, and E, in the perioperative period. The authors aim to explain the physiological effects of surgery on nutrition …

Treatment Of An Unusual Infection Following Anterior Cruciate Ligament Reconstruction, Daniel Warren, David Michaeli, Benjamin Estrada, James Slauterbeck

Western Journal of Orthopaedics

The authors present an uncommon complication of pediatric anterior cruciate ligament (ACL) reconstruction involving a rare organism in the setting of multiple patient-specific factors that altered treatment. Management of postoperative mycobacterial infections requires thorough knowledge of the side effects of each medication used. Prolonged use of a fluoroquinolone in the setting of ACL reconstruction graft healing introduces the risk of injury to the graft, and tactful patient counseling must be employed to help diminish this risk. The potential for ototoxicity secondary to extended aminoglycoside use is especially worrisome and should be monitored. This plan required careful balancing of several important …

Pelvic Ring Injury Secondary To Traumatic Vaginal Delivery: A Case For Early Surgical Fixation, Tyler J. Chavez, Taylor P. Gurnea, Hernan Lebensohn, Johnathan P. Jensen, Samer Kakish

Western Journal of Orthopaedics

During the gestational period, the body undergoes a normal physiologic widening of the pubic symphysis in preparation for childbirth. Although exceedingly rare, despite increased laxity, the pelvic ring remains at risk of serious injury during delivery. The current body of literature on this topic includes only a few case reports without clear guidance on the acute management of non-physiologic pubic symphysis widening and pelvic ring injuries following childbirth. The authors present a case of a 31-year-old pregnant woman (G2P0101) who sustained an APC2 (OTA B2.3) pelvic ring injury during vaginal delivery requiring open reduction and internal fixation for failure to …

Reconstruction Of Charcot Foot Deformity Using Circular External Fixators And Fusion: A Case Report, M Bryant Transtrum, Allen Wang, Diego Sanchez, Joshua Tadlock, Ahmed Thabet, Amr Abdelgawad

Western Journal of Orthopaedics

Charcot neuroarthropathy is a complication of the joints in patients with peripheral neuropathy, characterized by massive hyperemia, bone resorption, and joint destruction. The complex deformities that can result may lead to subsequent ulcers, osteomyelitis, and eventually limb amputation. Concurrent soft-tissue pathologies, such as ulcers and infections, complicate operative management. Thus, deformity correction may be necessary for wound healing before final fixation. In this case report, the authors describe a 48-year-old man who presented with a severe Charcot deformity of the foot and accompanying non-healing diabetic foot ulcer overlying the talar head. The authors elected to proceed with staged reconstruction, starting …

Differences In Ct Scan Measurements Of Femoral Neck Shaft Angle And Acetabular Version Among Sex, Age, And Ethnicity From A Large Cadaveric Database, Bryce N. Clinger, Scott Plaster, River S. Fine, Justin R. Marshall, Dustin L. Richter

Western Journal of Orthopaedics

Background: Management of proximal femur and acetabular pathologies, such as femoroacetabular impingement, hip osteoarthritis, or hip fractures, requires an understanding of the patient’s anatomy for accurate diagnosis and treatment. Variability in femoral neckshaft angle (FNA) and acetabular version (AV) has been shown, but little insight into differences between ages, ethnicities, and sexes has been evaluated. Methods: Two hundred and fifty cadaveric specimens from the New Mexico Decedent Image Database were evenly divided by sex and among five ethnic groups (Asian American, Black/African American, Hispanic, Native American, White). Using multiplanar reconstruction, thincut computed tomography scans were reviewed by three independent observers. …
