Intra-Articular Osteoid Osteoma Of The Elbow: A Case Report, Catherine M. Westbom, John E. Nolan, Nathan T. Morrell

Western Journal of Orthopaedics

A 24-year-old woman, with 5 years of left elbow pain, was given a preliminary diagnosis of focal pigmented villonodular synovitis based on magnetic resonance imaging. She underwent arthroscopic debridement and was found to have an intra-articular bony mass. Histopathology was consistent with an intra-articular osteoid osteoma. The mass was removed arthroscopically with excellent symptomatic improvement. There was no recurrence of symptoms at 1 year follow-up.

Arthroscopic Management Of Focal Pigmented Villonodular Synovitis In The Scaphotrapeziotrapezoidal Joint, John E. Nolan, Brian W. Gross, Nathan T. Morrell

Western Journal of Orthopaedics

A 43-year-old man presented with persistent wrist pain and loss of range of motion after nonoperative therapy. Magnetic resonance imaging showed features consistent with pigmented villonodular synovitis (PVNS) of the scaphotrapeziotrapezoidal joint. He underwent arthroscopic excision and synovectomy. At 2 years postoperatively, he had no symptomatic recurrence. This case shows the importance of considering PVNS for chronic pain of small joints, and it highlights the viability for arthroscopic synovectomy as a treatment option.

Predicting Running Ability After Lower Extremity Amputation: A Review, Rebecca Dutton

Western Journal of Orthopaedics

The ability to ambulate with a prosthesis after lower extremity limb loss is an important determinant of functional independence and quality of life. Some individuals may be capable of achieving higher levels of mobility (eg, running) that can further improve function, physical health, and mental health. Thus, a fundamental understanding of the variables that help predict ambulation ability after lower limb loss is important. Particular attention should be given to modifiable predictors, as interventions directed at these conditions can help facilitate optimal mobility and function. This article reviews various factors that influence the ability

Malreductions Following Intramedullary Nail Fixation Of Femur Shaft Fractures, Jory Wasserburger, Christopher Kurnik, Thomas A. Decoster

Western Journal of Orthopaedics

Femur shaft fractures are common injuries frequently treated with intramedullary fixation. Although satisfactory alignment is usually achieved, malreductions can happen in sagittal and coronal planes, as well as along the longitude axis. The causes of malposition with femoral nailing include fracture location, comminution, and suboptimal technique. We identify the most common patterns of malreduction of nailed femu

Cost Analyses Of Nonoperative Treatment Of Sports-Medicine Conditions Are Lacking, Casey Slattery, Jai Yao, Amy Cizik, Mia S. Hagen

Western Journal of Orthopaedics

The purpose of this study was to qualitatively review existing studies that examined cost data within sports medicine. A literature search was conducted for all economic studies related to sports-medicine conditions from 2000 to 2017 within the United States. Area of analysis, data source utilized, and the type of collected cost data was identified. There were 29 studies that met criteria, with the majority of studies (60%) focused on rotator cuff repair and anterior cruciate ligament reconstruction. Substantial variability in data source, practice setting, data metrics, and reported measures makes interpretation of existing reports challenging. Greater diversity in topics and …

Can The Contralateral Knee Effectively Estimate Pre-Injury Patellar Height? A Control Study, Benjamin Albertson, Andrew Ockuly, Ian Fletcher, Daniel Wascher

Western Journal of Orthopaedics

Introduction: Patellar height abnormalities have been associated with patellar instability, which is common among adolescents and young adults. Pre-injury patellar height is often unknown in patients with a patellar instability episode. The purpose of this study was to determine whether patellar height of one knee could effectively estimate patellar height of the contralateral knee in control patients between the ages of 13 and 25 years. Methods: A retrospective chart review was conducted to identify 40 patients who obtained bilateral knee radiographs with no prior surgical intervention or diagnosis of injury to the extensor mechanism. CatonDeschamps Index (CDI) was measured by …

The Vulcan Sign: A Radiographic And Clinical Indicator Of Plantar Plate And Collatoeral Ligament Injury, Katherine Gavin

Western Journal of Orthopaedics

Introduction: There is no consensus on terminology used to describe the radiographic and clinical findings commonly encountered in second metatarsophalangeal (MTP) instability. We propose the use of a consensus term, the Vulcan sign, to describe the deformity commonly seen in second MTP instability and verify its utility as an adjunct in the diagnosis and treatment of plantar plate and collateral ligament pathology. Methods: We retrospectively evaluated preoperative anteroposterior weight-bearing x-rays of 156 feet of patients who underwent operative intervention for second MTP instability and the presence of a Vulcan sign at the second webspace, defined as more than 50% medial …

The Importance Of The Screening Anteroposterior Pelvis Radiograph In Trauma Patients: A Level-1 Trauma Center's Experience With Traumatic Hip Dislocations, Ansab Khwaja, Brad Askam, Matt Morin, Aditya Manoharan

Western Journal of Orthopaedics

Background: Advanced Trauma Life Support guidelines strongly recommend obtaining anteroposterior (AP) pelvis radiographs when evaluating patients with traumatic injuries. Recently, there has been a trend at our institution to forego AP pelvis radiographs, and to obtain computed tomography (CT) scans as the initial imaging modality of the pelvis instead. Lifesaving interventions, such as the application of a pelvic binder, can be delayed due to the time it takes to complete a primary survey and a CT scan. This study aims to evaluate the effects of bypassing an AP pelvis radiograph on the management of acute traumatic dislocations of the hip. …

Inter- And Intra-Observer Differences In Proximal Fifth Metatarsal Fractures, Benjamin Packard, Kathryn Yeagar, Richard A. Miller, Katherine Gavin

Western Journal of Orthopaedics

Introduction: Proximal fifth metatarsal fractures are common. When using the Lawrence and Botte Classification for these injuries, they are classified as type 1, 2, and 3. Identifying the zone of injury is crucial to guide treatment. The authors hypothesize that interand intra-observer reliability of these fractures is low. Methods: Anteroposterior (AP), lateral, and oblique x-rays of 60 patients with isolated fifth metatarsal base fractures were reviewed. Five physicians evaluated the radiographs and classified the fractures as type 1,2, or 3. Each of the three radiographic views were examined separately. Results were then analyzed for inter- and intra-observer reliability. Results: Sixty …

Quantifying Coverage Of A Distal Radius Volar Plate Using A Novel Pronator Quadratus Rotational Muscle Flap Technique, Christina Salas, Leslie Neher, Joshua Romero, Camille Aubin-Lemay

Western Journal of Orthopaedics

Background: Flexor tenosynovitis and tendon rupture are rare, yet serious complications after treatment of a fractured distal radius with a volar plate. The highest incidents of rupture are associated with the plate on or distal to the watershed line of the radius. While studies have shown that reattachment of the pronator quadratus (PQ) following plating does not lead to improved measures in grip strength or range of motion, it may reduce the incidence of these complications. Reattachment of the PQ after a standard approach does not often capture the distal edge of the plate. We report results of a new …

Aspetic Nonunion Of Long Bones In Children: A Report Of Twelve Cases, Rami Khalifa, Amr Abdelgawad, Ahmed M. Thabet

Western Journal of Orthopaedics

Background: There are very few reports in the literature that directly address nonunion in children. The current study aimed to present a series of long bones nonunion in children following fractures and corrective osteotomies. Methods: This was a retrospective study that included pediatric patients diagnosed with nonunion following long bone fractures or corrective osteotomies. Patients with nonunion following femoral neck or lateral humeral condyle fractures were excluded. The clinical and radiological records were retrospectively analyzed. Results: Eight patients developed nonunion after fractures, while four patients had nonunion after corrective osteotomies. The mean age at the time of surgical procedure for …

The Versatility Of Taylor Spatial Frame In Treating Comple Posttraumatic Deformities Of The Lower Extremity, Rami Khalifa, Amr Abdelgawad, Ahmed M. Thabet

Western Journal of Orthopaedics

Background: The Taylor Spatial Frame (TSF) is a multiplanar external fixator with a computerized web-based program to provide accurate fractures reduction and deformity correction. This study aimed to evaluate our results after the treatment of complex lower extremity injuries with the external fixators including TSF. Methods: This retrospective case series included eight patients with complex lower extremity injuries treated with TSF. The medical records and radiographs were reviewed. The ASAMI score was used as an outcome measure. Statistical analysis used Microsoft Excel descriptive statistics. No inferential statistical tests were done owing to the small sample size. Results: The mean age …

Nuclear Morphology And The Biology Of Cancer Cells, Edgar G. Fischer

Pathology Research and Scholarship

BACKGROUND: For more than a century, diagnostic pathologists have used morphologic abnormalities of the nucleus as essential diagnostic features to distinguish benign from malignant cells. These features include nuclear enlargement and increased nuclear-to-cytoplasmic ratio, nuclear membrane irregularities, hyperchromasia, and abnormal chromatin distribution. As our knowledge about the genetic and epigenetic abnormalities of cancer cells has increased in recent decades, the pathophysiologic mechanisms that underlie these morphologic abnormalities remain incompletely understood.

SUMMARY: This review attempts to summarize biologic abnormalities in malignant cells related to these morphologic changes. The molecular anatomy of the nuclear envelope in normal and malignant cells is discussed …

Albuquerque Journal Interviews Maryam Ahranjani, Many Want Police Out Of Schools Across Nm, Maryam Ahranjani, Shelby Perea

Faculty Scholarship

In Albuquerque, University of New Mexico School of Law associate professor Maryam Ahranjani and Hope Pendleton, a board member of the Black Law Student Association at UNM, are saying now is the time to remove officers from schools.

“There’s a lot of unfortunate downstream negative repercussions for children from having police officers in schools,” Ahranjani said.

Pendleton and Ahranjani helped write a letter to APS Superintendent Raquel Reedy and her leadership team that says funds earmarked for the APS Police Department would be better spent addressing this counselor-to-student ratio and investing in other personnel.

Molecular Interplay Between Dormant Bone Marrow-Resident Cells (Bmrcs) And Ctcs In Breast Cancer., Debasish Boral, S Ray Kenney, Dario Marchetti, Haowen N. Liu

Pathology Research and Scholarship

Despite widespread knowledge that bone marrow-resident breast cancer cells (BMRCs) affect tumor progression, signaling mechanisms of BMRCs implicated in maintaining long-term dormancy have not been characterized. To overcome these hurdles, we developed a new experimental model of clinical dormancy employing patient-isolated Circulating Tumor Cells (de novo CTCs) and their injection in xenografts with subsequent tumor monitoring and CTC characterization (ex vivo CTCs). We hypothesized that significant distinctions exist between signaling pathways of bone marrow-homing vs metastasis-competent CTCs upon transplantation in xenografts. Comparative transcriptomic analyses of ex vivo vs de novo CTCs identified increased mTOR signaling-a critical pathway frequently dysregulated in …

(SīˈTĭng) Detroit: Vision And Dispossession In A Midwest Bordertown, Matthew J. Irwin

American Studies ETDs

This dissertation examines the relationality of dispossession, racialization, and migration in Detroit, connecting the neoliberal rationality of (re)development to its foundations in Indigenous dispossession and racialized labor. “(Sīˈtĭng) Detroit” understands Detroit as a bordertown, where “the border” is the organizing structure and condition for the operation of settler colonialism in Detroit. From the international boundary to the county line, the border is the on-the-ground, everyday method for controlling space, disciplining populations, and limiting mobility for racialized subjects. To examine possession and belonging in a Black city on an international border, this dissertation introduces a “(sīˈtĭng)” — a methodology for locating …
