Autologous matrix-induced chondrogenesis (AMIC) has gained popularity in the treatment of osteochondral lesions of the talus. Previous studies have presented promising short-term results for AMIC talar osteochondral lesion repair, a 1-step technique using a collagen type I/III bilayer matrix. The aim of the present study was to investigate the mid-term effects. The 5-year results of a prospective cohort study are presented. All patients underwent an open AMIC procedure for a talar osteochondral lesion. Data analysis included general demographic data, preoperative magnetic resonance imaging findings, intraoperative details, and German version of the Foot Function Index (FFI-D) scores preoperatively and at 1 and 5 years after surgery...

Foot involvement is common in juvenile idiopathic arthritis (JIA) but is often unrecognized and difficult to treat. This study was done to assess clinical and radiological involvement of the feet and its impact on function in Indian children with enthesitis-related arthritis (ERA). We enrolled consecutive children with ERA with disease duration of less than 5 years. All patients underwent clinical examination of the feet and filled the juvenile arthritis foot index (JAFI) questionnaire. Ultrasound (US) of foot joints and entheses and extremity magnetic resonance imaging (MRI) scan of one foot were done...

The present report illustrates a very rare case report of a foreign body granuloma of the foot associated with a 2-year period of a retained spongeous rubber foreign body after a penetrating injury. Because it appeared almost 2 years after the injury, the history of trauma was minimized, the foreign body had migrated from the plantar to the dorsal side of the foot, and the radiographic appearance resembled a malignant process, it was difficult to rule out the possibility of a malignant tumor. This case shows the weakness of magnetic resonance imaging in detecting spongeous rubber in the body...

Glomus tumors are painful benign neoplasms. They commonly present in the hand and are mostly solitary lesions. We report a rare case of multiple glomus tumors in the lower leg. Moreover, 1 of the tumors was in the tarsal tunnel. Resection of the tumors resulted in the early diagnosis of glomus tumors and complete symptom relief. Because of its rarity, diagnosing an extradigital glomus tumor is difficult. Recognition of glomus tumors allows for an early diagnosis and resection, and preoperative magnetic resonance imaging helps in the detection of multiple lesions...

Arthroereisis of the subtalar joint is a common surgical technique in Europe for the management of flexible flatfoot in the pediatric population. In most cases, it is performed using a calcaneo-stop metallic screw. Despite the good clinical results, screw removal is always advised after 2 to 3 years. The use of a bioabsorbable screw might overcome the need for a second operation to remove a nonabsorbable device. We report the results of a biodegradable calcaneo-stop screw at a minimum of 4 years of follow-up...

We determined and compared the effectiveness of low-level laser therapy (LLLT), therapeutic ultrasound (US) therapy, and extracorporeal shock wave therapy (ESWT) using magnetic resonance imaging (MRI). We performed a randomized, prospective, comparative clinical study. A total of 60 patients with a diagnosis of chronic plantar fasciitis were divided randomly into 3 treatment groups: group 1 underwent 15 sessions of LLLT (8 J/cm(2); 830 nm); group 2 underwent 15 sessions of continuous US (1 mHz; 2 W/cm(2)); and group 3 underwent 3 sessions of ESWT (2000 shocks)...

PURPOSE: The purposes of this study are to characterize magneto-endosymbiont (ME) labeling of mammalian cells and to discern the subcellular fate of these living contrast agents. MEs are novel magnetic resonance imaging (MRI) contrast agents that are being used for cell tracking studies. Understanding the fate of MEs in host cells is valuable for designing in vivo cell tracking experiments. PROCEDURES: The ME's surface epitopes, contrast-producing paramagnetic magnetosomal iron, and genome were studied using immunocytochemistry (ICC), Fe and MRI contrast measurements, and quantitative polymerase chain reaction (qPCR), respectively...

INTRODUCTION: Mycetoma is a chronic granulomatous infection. It is caused by actinomycetes or fungi. It is common in tropical countries and males. Predisposing conditions include malnutrition, poor hygiene, history of trauma, wounds on barefeet, and systemic infections. Eumycotic mycetoma commonly involves lower extremities whereas actinomycosis affects the cervicofacial, thoracic, and abdominal regions. Mycetoma presents with a chronic indurated ulcerated plague with swelling and yellowish discharge of sulfur granules...

Primary somatosensory cortex (S1) processes somatosensory information and is composed of multiple subregions. In particular, tactile information from the skin is encoded in three subregions, namely Brodmann areas (BAs) 3b, 1 and 2, with each area representing a complete map of the contralateral body. Although, much is known about the somatotopic organization of the hand in human S1, less research has been carried out regarding the somatotopic maps of the foot and leg in S1. Moreover, a latero-medial S1 organization along the superior part of the postcentral gyrus has been reported when moving from hip to toes, yet to date there is no study investigating leg/foot maps within the different subregions of S1...

PURPOSE: Magneto-endosymbionts (MEs) show promise as living magnetic resonance imaging (MRI) contrast agents for in vivo cell tracking. Here we characterize the biomedical imaging properties of ME contrast agents, in vitro and in vivo. PROCEDURES: By adapting and engineering magnetotactic bacteria to the intracellular niche, we are creating magneto-endosymbionts (MEs) that offer advantages relative to passive iron-based contrast agents (superparamagnetic iron oxides, SPIOs) for cell tracking...

We present a retrospective review of 8 patients (6 women and 2 men, with an age range of 46-80 years; mean age, 60.2 years) in whom sonography was used to diagnose a calcaneal stress fracture. Sonography was performed because of a clinical suspicion of soft tissue injuries. Two patients were first assessed by standard radiography; for the remaining patients, sonography was the first imaging technique used. Patients were subsequently examined by magnetic resonance imaging, except for 1 patient in whom the diagnosis was made only on a clinical-sonographic correlation...

Foot foreign body granulomas can mimic malignancies, especially when the history and unusual location pose a diagnostic dilemma. We report the case of a 33-year-old male with delayed-onset progressive swelling over the foot dorsum after a sharp injury through the plantar aspect of the foot. The unusual presentation and radiolucency warranted further radiologic evaluation, which revealed a benign foot swelling. An excision biopsy and histopathologic examination revealed a rubber body granuloma. No recurrence of the granuloma was noted during the 11-month follow-up period after removal of the offending agent...

Myelomeningocele (MMC) is a costly lifetime disease with many comorbidities, including sensory and motor lower limb disability, bladder/bowel dysfunction, scoliosis, club foot, and hydrocephalus. MMC treatment options have changed over time because routine use of fetal ultrasonography and MRI has provided prenatal diagnosis and the potential for fetal surgery. There is still no consensus on how to treat the MMC diagnoses prenatally, mainly related to the infrastructure required to operate on pregnant patients...

Diabetes patients display gait alterations compared to controls including a higher metabolic cost of walking. This study aimed to investigate whether differences in external moment arm (ExtMA) and effective mechanical advantage (EMA) at the ankle in diabetes patients could partly explain the increased cost of walking compared to controls. Thirty one non-diabetic controls (Ctrl); 22 diabetes patients without peripheral neuropathy (DM) and 14 patients with moderate/severe diabetic peripheral neuropathy (DPN) underwent gait analysis using a motion analysis system and force plates...

OBJECTIVE: Foot osteoarthritis (OA) is very common but underinvestigated musculoskeletal condition and there is little consensus as to common magnetic resonance imaging (MRI) features. The aim of this study was to develop a preliminary foot OA MRI score (FOAMRIS) and evaluate its reliability. METHODS: This preliminary semiquantitative score included the hindfoot, midfoot, and metatarsophalangeal joints. Joints were scored for joint space narrowing (JSN; 0-3), osteophytes (0-3), joint effusion/synovitis, and bone cysts (present/absent)...

The complex anatomy and function of the foot and ankle can make it difficult to determine the cause of symptoms in patients with foot and ankle pathology. Following initial clinical and radiographic assessment, additional imaging with magnetic resonance imaging may be required, which is often seen as the modality of choice. Although sensitive to pathological changes in bone metabolism and vascularity, technetium-99m (Tc-99m) bone scintigraphy often lacks the specificity and resolution required to evaluate the structures of the foot and ankle...

Evaluation of the correlation between disease activity and joint involvement was assessed by MRI in the clinically dominant foot of patients with RA. We conducted a cross-sectional descriptive study of 55 patients with RA, who were subjected to clinical evaluation and MRI assessment. Imaging of the clinically dominant foot was performed, and both the Disease Activity Score 28 (DAS28-CRP) and the Health Assessment Questionnaire-Disability Index (HAQ-DI) were measured. The majority of patients classified as in clinical remission presented some degree of inflammatory activity upon MRI evaluation...

BACKGROUND: Corpora amylacea (CA) are accumulations of polyglucosan bodies typically found in astrocytic foot processes, and rarely, can mimic neoplasm. CA accumulation has also been associated with seizure disorders. We report the first case of a histologically confirmed intracranial, intraparenchymal CA lesion mimicking a low-grade glioma and manifesting as a seizure. CASE DESCRIPTION: A 43-year-old man presented after a general tonic-clonic (GTC) seizure. Brain magnetic resonance imaging (MRI) revealed a small lesion in the right mesial temporal lobe with radiologic features of a low-grade glioma...
