BACKGROUND: Along with significant case transmission, hospitalizations, and mortality experienced during the global severe acute respiratory syndrome coronavirus 2 pandemic, there existed a disruption in the delivery of health care across multiple specialties. We studied the effect of the pandemic on inpatients with diabetic foot problems in a Level I trauma center in central Ohio.

METHODS: A retrospective chart review of patients necessitating a consultation by the foot and ankle surgery service were reviewed from the first 8 months of 2020. A total of 270 patients met the inclusion criteria and were divided into prepandemic (n = 120) and pandemic …

Challenging The Endovascular Era: Open Bypass From Distal Sfa To Pta Using Ipsilateral Reversed Saphenous Vein For Critical Limb Ischemia, Suraj Pai, Suresh Pai, Sanya Mukhida, Aditya Nair

Manipal Journal of Medical Sciences

Open surgical revascularization remains a vital option in select patients with critical limb ischemia (CLI), especially when endovascular interventions are not feasible. We present a case of a 69 -year-old diabetic male with Rutherford class 5 CLI, initially planned for above-knee amputation due to extensive arterial occlusion and severe rest pain. The disease was attributed to his very significant smoking history which was stopped only recently. His CT Angiogram study revealed occlusion of distal superficial femoral artery with suboptimal distal reformation. Given the absence of endovascular options, he underwent successful open bypass from the distal superficial femoral artery (SFA) to …

Home-Based Electrical Stimulation To Accelerate Wound Healing-A Double-Blinded Randomized Control Trial, Alejandro Zulbaran-Rojas, Catherine Park, Nesreen El-Refaei, Brian Lepow, Bijan Najafi

School of Podiatric Medicine Publications

People with diabetic foot frequently exhibit gait and balance dysfunction. Recent advances in wearable inertial measurement units (IMUs) enable to assess some of the gait and balance dysfunction associated with diabetic foot (i.e., digital biomarkers of gait and balance). However, there is no review to inform digital biomarkers of gait and balance dysfunction related to diabetic foot, measurable by wearable IMUs (e.g., what gait and balance parameters can wearable IMUs collect? Are the measurements repeatable?). Accordingly, we conducted a web-based, mini review using PubMed. Our search was limited to human subjects and English-written papers published in peer-reviewed journals. We identified …

Middle Cuneiform Stress Fracture In A Postal Worker: A Case Report, Stephanie N. Campbell, Jacob M. Jones, Raul Aviles, Loren K. Spencer, John J. Anderson

School of Podiatric Medicine Publications

This report is to supplement the limited nature of isolated cuneiform fractures. Cuneiform fractures are identified as “low risk stress fracture” but with delayed diagnosis may cause prolonged treatment due to continued foot pain. Delayed diagnosis may be due to low sensitivity on radiographic exam and/or low suspicion clinically due to the rare involvement of isolated cuneiform fractures.

Joint Angle Variability Is Altered In Patients With Peripheral Artery Disease After Six Months Of Exercise Intervention, Farahnaz Fallahtafti, Zahra Salamifar, Mahdi Hassan, Hafizur Rahman, Iraklis Pipinos, Sara A. Myers

School of Podiatric Medicine Publications

Supervised exercise therapy (SET) is a conservative non-operative treatment strategy for improving walking performance in patients with peripheral artery disease (PAD). Gait variability is altered in patients with PAD, but the effect of SET on gait variability is unknown. Forty-three claudicating patients with PAD underwent gait analysis before and immediately after a 6-month SET program. Nonlinear gait variability was assessed using sample entropy, and the largest Lyapunov exponent of the ankle, knee, and hip joint angle time series. Linear mean and variability of the range of motion time series for these three joint angles were also calculated. Two-factor repeated measure …

Articles that involved Charcot arthropathy, case reports, small case series, review articles, commentaries, nonhuman studies, and non-English articles were excluded. The Quality Assessment of Diagnostic Accuracy Studies (QUADAS-2) tool was used to rate the bias of each study. A meta-analysis was performed using random-effects and inverse variance methods. The search yielded 1192 …

Surgical Treatment Of Multiple Deforming Xanthomas Of The Foot And Ankle With Complete Excision And Rotational Skin Flaps: A Case Report, Qanita Ali, Rachelle Randall, Lawrence M. Fallat

Articles

Xanthomas are cholesterol rich nodular dermal lesions characterized by lipid-laden macrophages that accumulate in skin and tendons.1 These lesions are frequently associated with hyperlipidemia disorders characterized by impaired cholesterol metabolism and accelerated atherosclerotic plaque development.2 Until recently, xanthomas were considered mere cosmetic lesions, however extensive evidence has shown that the presence of xanthomas signify increased cardiovascular risk and reduced average lifespan.3 Treatment centers around lipid lowering agents and rarely are these masses large enough to require surgical resection, thus there is very little literature discussing proper surgical excision.4, 5 We present a rare case of a 65 year old female …

Covid-19 And Incidence Of Necrotizing Fasciitis: A Case Study, Tehreem Sajjad, Carmen Johnson, Janet Baatile-Ajrouche

Posters

COVID-19 manifests as a flu-like respiratory infection affecting multiple organ systems. Symptoms range from mild viral illness to severe acute respiratory infection. There is no definitive relationship between COVID-19 and cellulitis, inflammatory myositis, vasculitis, or necrotizing fasciitis. It is interesting to note that angiotensin-converting enzyme 2 (Receptor for SARS-CoV-2) is present on endothelial cells in multiple organs, including dermal blood vessels and arterial smooth muscle cells. There are several theories that have formed to explain the relationship between COVID-19 and a necrotizing fasciitis infection. This study presents one unique case of an unvaccinated COVID+ patient and the necrotizing fasciitis infection …

A Case Series Of Three Patients With Rare Pantalar Dislocation, Marissa Mogavero, Andrew Robitaille, Lawrence M. Fallat

Articles

Total talar dislocations are rare, significant surgical challenges for foot and ankle surgeons. These dislocations can be very difficult to manually close-reduce, requiring immediate surgical intervention secondary to arterial impingement, pain and risk of skin necrosis attributable to skin tenting. In this case series, we report on three patients who presented to the emergency room following a traumatic ankle injury. Ankle radiographs and computed tomography (CT) scans were obtained, revealing pantalar dislocations. Closed reduction utilizing Charnley’s principles was attempted in the emergency room through manual accentuation of the deformity, traction and reduction. Closed reduction was unsuccessful in all three patients …

Effect Of Sensory Neuropathy On The Predictive Value Of Inflammatory Biomarkers For Osteomyelitis In Diabetic And Nondiabetic Patients With Foot Infections, Easton Ryan, Junho Ahn, Dane K. Wukich, Javier La Fontaine, Andrew Crisologo, Matthew Malone, Orhan Oz, Lawrence A. Lavery

School of Podiatric Medicine Publications

Objective: To investigate the predictive value of erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) in persons with and without diabetes with osteomyelitis (OM).

Methods: We evaluated 455 patients in a retrospective cohort study of patients admitted to the hospital with diabetic foot OM (n = 177), diabetic foot soft-tissue infections (STIs) (n = 176), nondiabetic OM (n = 51), and nondiabetic STIs (n = 51). Infection diagnosis was determined through bone culture, histopathologic examination for OM, and/or imaging (magnetic resonance imaging/single-photon emission computed tomography) for STI. The optimal cutoff values of ESR and CRP in predicting OM were determined …

A Rare Benign Soft-Tissue Chondroma In The Plantar Foot: A Case Report, Ashley Mariano, Lawrence M. Fallat

Articles

Extraskeletal chondromas are rare, benign cartilaginous neoplasms that are usually found in adults and often present as a slow growing solitary mass. We present a case of a 78-year-old male who initially presented with a painful hyperkeratotic lesion to the plantar aspect of his right foot resembling a porokeratosis. He noted increased pain when bearing weight. Initial radiographs revealed no osseous pathology, bone spurs or foreign bodies that correlated with the area of pain. Due to failed conservative treatment that consisted of regular debridement, surgical excision of the lesion was performed which revealed a large underlying hard nodule. The nodular …

Tibiotalocalcaneal Fusion With Bulk Femoral Head Allograft In A Patient With A Rare, Trauma Induced, Rigid, Cavovarus Foot Deformity, Josh Carroll, Joseph Wolf, Lawrence M. Fallat

Articles

Tibiotalocalcaneal (TTC) arthrodesis with bulk femoral head allograft is a commonly performed limb salvage procedure when dealing with complex deformity. However, little has been reported in patients who receive tibiotalocalcaneal arthrodesis with femoral head allografts for a rigid cavovarus foot type. The purpose of this case report was to examine the outcomes of a tibiotalocalcaneal arthrodesis with a femoral head allograft in a diabetic patient with a trauma induced rigid cavovarus deformity who had complete lateral dislocation of the talar body. The secondary purpose was to highlight the preservation of limb length in the surgical extremity when utilizing a tibiotalocalcaneal …

Perceived Instability, Pain, And Psychological Factors Predict Function And Disability In Individuals With Chronic Ankle Instability, Ashley M.B. Suttmiller, Julie M. Cavallario, Shelby E. Baez, Jessica C. Martinez, Ryan S. Mccann

Rehabilitation Sciences Faculty Publications

Context:

Chronic ankle instability (CAI) is associated with residual instability, pain, decreased function, and increased disablement. Injury-related fear has been associated with CAI, although its relationship to other impairments is unclear. The Fear-Avoidance Model is a theoretical framework hypothesizing a relationship between injury-related fear, chronic pain, pain catastrophizing, and disability. It has been useful in understanding fear's influence in other musculoskeletal conditions but has yet to be studied in those with CAI.

Objective:

To explore relationships between instability, pain catastrophizing, injury-related fear, pain, ankle function, and global disability in individuals with CAI.

Design:

Cross-Sectional Study

Allogenic Fibular Bone Graft Reconstruction With Complete Regeneration Of The Lateral Malleolus After En Bloc Resection Of A Distal Fibular Aneurysmal Bone Cyst: A Case Report, Kalli E. Mortenson, Lawrence M. Fallat

Articles

Aneurysmal bone cysts are expansile lytic lesions that most commonly affect the metaphysis of long tubular bones. These lesions are locally aggressive and predominately occur within the first two decades of life. Currently the most widely used surgical treatment involves intralesional curettage of the affected bone. However, there have been several reports of high recurrence rates with this technique. We present a case of a 12 year old female who presented with an aneurysmal bone cyst of the lateral malleolus of the right ankle. The patient underwent multiple surgeries and ultimately had complete surgical resection of the cystic lesion and …

The Phoenix Sign: Is It Due To Vasodilation? Blinded Prospective Comparing The Effects Of Papaverine To Lidocaine Without Epinephrine, Julia Aguirre

Symposium of Student Scholars

A neurological phenomenon has been observed clinically that when after a small amount of 1% lidocaine (usually less than .5cc’s) has been infiltrated adjacent to the Common Fibular (Peroneal) nerve under sonographic guidance, in patients with drop foot, or significantly weakened motor potentials of the lower extremity dorsiflexors (Extensor Hallucis Longus (EHL), Tibialis Anterior (TA), and Extensor Digitorum Longus (EDL)), the patient will regain partial or full dorsiflexion temporarily during the effect of this nerve block. This has been named the Phoenix Sign, in reference to ancient Greek folklore, as the non-functioning nerve (like the bird) becomes functional due to …

The Epidemiology, Evaluation, And Assessment Of Lateral Ankle Sprains In Athletes, G. Javier Cavazos Jr., Lawrence B. Harkless

School of Medicine Publications

Approximately 30,000 ankle injuries occur every day in the United States. With the incidence estimated at more than 3 million a year and at a rate of 2.15/1,000 in the U.S. alone, medical specialists and other healthcare providers caring for the foot and ankle must take notice. Despite the millions of ankle injuries sustained annually, the true incidence may be underestimated, as fewer than half of individuals with ankle sprains seek medical attention from healthcare professionals. The economic burden associated with the evaluation, diagnosis, and treatment is close to $4 billion annually. Ankle sprains account for half of all sports …

Cadaveric Endoscopic Gastrocnemius Recession Procedures To Identify Vital Anatomical Structures And Limit Intraoperative And Post-Operative Complications, Austin Combs

Undergraduate Distinction Papers

Gastrocnemius equinus contracture plays a role in a multitude of patient pathologies, conditions, and deformities seen in podiatric medicine (Barrett, 2011). Equinus deformity is associated with over 96% of the biomechanically-related foot and ankle pathologies including hallux valgus, metatarsalgia, capsulitis, pes planus, plantar fasciitis, tendonitis, and others (Deheer, 2015). These pathologies are linked with a decreased range of motion in the ankle joint specifically in dorsiflexion. Corrective approaches can be taken to reduce pathology if the patient presents prior to any major deformity. The aim of this study is to better define the location of the small saphenous vein and …

Streptococcus Pneumoniae, S. Mitis, And S. Oralis Produce A Phosphatidylglycerol-Dependent, Ltas-Independent Glycerophosphate-Linked Glycolipid, Yahan Wei, Luke R. Joyce, Ashley M. Wall, Ziqiang Guan, Kelli L. Palmer

School of Podiatric Medicine Publications

Lipoteichoic acid (LTA) is a Gram-positive bacterial cell surface polymer that participates in host-microbe interactions. It was previously reported that the major human pathogen Streptococcus pneumoniae and the closely related oral commensals S. mitis and S. oralis produce type IV LTAs. Herein, using liquid chromatography/mass spectrometry-based lipidomic analysis, we found that in addition to type IV LTA biosynthetic precursors, S. mitis, S. oralis, and S. pneumoniae also produce glycerophosphate (Gro-P)-linked dihexosyl (DH)-diacylglycerol (DAG), which is a biosynthetic precursor of type I LTA. cdsA and pgsA mutants produce DHDAG but lack (Gro-P)-DHDAG, indicating that the Gro-P moiety is derived from phosphatidylglycerol …

Lumbopelvic Stability And Trunk Muscle Contractility Of Individuals With Chronic Ankle Instability, Ryan S. Mccann, Kelly Johnson, Ashley M.B. Suttmiller

Rehabilitation Sciences Faculty Publications

BACKGROUND: Chronic ankle instability (CAI) results in hip neuromuscular impairments that can perpetuate dysfunction through reduced lumbopelvic stability and subsequent malpositioning of the lower body during functional movement. Lumbopelvic stability might be further impaired through changes in trunk muscular contractility. However, lumbopelvic stability and trunk muscle morphology have not been compared between individuals with and without CAI.

PURPOSE: To compare lumbopelvic stability and trunk muscle contractility between individuals with and without chronic ankle instability (CAI) and determine if lumbopelvic stability and trunk muscle contractility are associated with self-reported function.

STUDY DESIGN: Case-control study.

METHODS: Ten individuals with CAI, 10 …
