Musculoskeletal anatomy is widely known to have components that stray from the norm in the form of variant muscle and tendon presence, absence, origin, insertion, and bifurcation. Although these variant muscles and tendons might be deemed incidental and insignificant findings by most, they can be important contributors to pathologic physiology or, more importantly, an option for effective treatment. In the present case report, we describe a patient with phocomelia and Müllerian abnormalities secondary to in utero thalidomide exposure...

A three-dimensional foot finite element model with actual geometry and non-linear behavior of tendons is presented. The model is intended for analysis of the lower limb tendon forces effect in the inner foot structure. The geometry of the model was obtained from computational tomographies and magnetic resonance images. Tendon tissue was characterized with the first order Ogden material model based on experimental data from human foot tendons. Kinetic data was employed to set the load conditions. After model validation, a force sensitivity study of the five major foot extrinsic tendons was conducted to evaluate the function of each tendon...

Diabetic foot ulcers may result in loss of an extremity and may even lead to mortality. The use of comprehensive foot care programs which include early screening and evaluation of problems, foot care education, preventive therapy and referral to specialists has been shown to reduce amputation rates by 49-85 [percent]. A 51-year-old woman with Type 2 diabetes under surveillance for nine months was referred from the emergency department. She presented with an entirely inflamed right foot with ulcer covering two-thirds proximal of the foot for 30 days' duration...

BACKGROUND: First metatarsal protrusion distance (MPD) has been commonly studied as a characteristic of hallux valgus deformity. To date, the majority of investigations have used radiographic methods, with most reporting first metatarsal (ray) protrusion to be associated with deformity. As an alternative, this study used a three dimensional (3D) image acquisition and data analysis method to quantify MPD. METHODS: Magnetic resonance images were acquired in weightbearing on 29 women (19 with hallux valgus; 10 controls)...

We encountered a rare case of a periosteal ganglion cyst at the plantar aspect of the metatarsal that induced a stress fracture in a 77-year-old female. The clinical manifestation of the plantar ganglion cyst of the foot was not evident because of its location deep beneath the plantar fascia. A pressure cortical indentation was detected at the metatarsal neck on the initial radiographs. Magnetic resonance imaging showed a stress fracture of the metatarsal with a ganglion cyst. The stress fracture was thought to have resulted from several factors, including structural weakness due to bony absorption from the ganglion cyst, osteoporosis that induced a fragility fracture, and a load-induced fatigue fracture...

INTRODUCTION: Spinal bronchogenic cysts are rare findings, with only four cases of lumbar bronchogenic cysts reported in the literature. All of these bronchogenic cysts involved the conus medullaris. We present the first case of a lumbar bronchogenic cyst and arachnoid cyst arising from the cauda equina in a 68-year-old male. Uniquely, this bronchogenic cyst also contained components of an arachnoid cyst. METHODS: Magnetic resonance imaging (MRI) demonstrated a compressive cystic lesion at the level of the L3 vertebra splaying the cauda equina...

Verrucous hemangioma is an uncommon congenital vascular malformation, which may clinically masquerade angiokeratoma, lymphangioma circumscriptum, or malignant melanoma. Differentiation is essential owing to varied therapeutic and prognostic implications. We present a rare case of multiple verrucous hemangiomas in a teenage girl who presented with multiple warty lesions over the dorsal aspect of the left foot since birth. Magnetic resonance imaging (MRI) scan was suggestive of a vascular malformation, and skin biopsy showed ectatic blood vessels extending from the papillary dermis into the subcutaneous tissue, diagnostic of verrucous hemangioma...

A 24-year-old woman fell while ice climbing and landed on her left foot. Radiographs were taken and read as noncontributory. Eight days after the injury, the patient was still unable to bear weight due to significant pain, so she self-referred to physical therapy. Following evaluation, she was referred to primary care for further imaging to rule out fracture. The physician ordered magnetic resonance imaging, which revealed a left mildly displaced fracture of the intra-articular lateral process of the talus...

BACKGROUND: The most common cause of degeneration of the posterior tibial tendon is a congenital valgus deformity of the calcaneus. Other associated pathologies are forefoot supination, forefoot abduction and shortening of the gastrocnemius muscle. DIAGNOSTICS: Loaded x‑rays of the foot in three planes as well as the hindfoot alignment view enable evaluation of the axis of the foot under static loading conditions. The posterior tibial tendon can be imaged with ultrasound and magnetic resonance imaging (MRI)...

Although postcontrast imaging has been used for many years in musculoskeletal imaging, dynamic contrast enhanced (DCE) MRI is not routinely used in many centers around the world. Unlike conventional contrast-enhanced sequences, DCE-MRI allows the evaluation of the temporal pattern of enhancement in the musculoskeletal system, perhaps best known for its use in oncologic applications (such as differentiating benign from malignant tumors, evaluating for treatment response after neoadjuvant chemotherapy, and differentiating postsurgical changes from residual tumor)...

The mechanism underlying brain region organization for motor control in humans remains poorly understood. In this functional magnetic resonance imaging (fMRI) study, right-handed volunteers were tasked to maintain unilateral foot movements on the right and left sides as consistently as possible. We aimed to identify the similarities and differences between brain motor networks of the two conditions. We recruited 18 right-handed healthy volunteers aged 25 ± 2.3 years and used a whole-body 3T system for magnetic resonance (MR) scanning...

Pathological abnormality of the peroneal tendons is an under-appreciated source of lateral hindfoot pain and dysfunction that can be difficult to distinguish from lateral ankle ligament injuries.Enclosed within the lateral compartment of the leg, the peroneal tendons are the primary evertors of the foot and function as lateral ankle stabilisers.Pathology of the tendons falls into three broad categories: tendinitis and tenosynovitis, tendon subluxation and dislocation, and tendon splits and tears. These can be associated with ankle instability, hindfoot deformity and anomalous anatomy such as a low lying peroneus brevis or peroneus quartus...

Aquaporin-4 (AQP4) is the predominant water channel in mammalian CNS where it is localized at the perivascular astrocytic foot processes abutting brain microvessels. Several lines of evidence suggest that AQP4 is involved in important homeostatic functions and that mislocalization of the perivascular pool of AQP4 is implicated in several different brain disorders. A recent study suggests that the differential susceptibility of midbrain dopaminergic neurons to the parkinsonogenic toxin 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) depends on the expression of AQP4...

OBJECTIVE: Diagnosing bone infection in the diabetic foot is challenging and often requires several diagnostic procedures, including advanced imaging. We compared the diagnostic performances of MRI, radiolabeled white blood cell (WBC) scintigraphy (either with (99m)Tc-hexamethylpropyleneamineoxime [HMPAO] or (111)In-oxine), and [(18)F]fluorodeoxyglucose positron emission tomography ((18)F-FDG-PET)/computed tomography. RESEARCH DESIGN AND METHODS: We searched Medline and Embase as of August 2016 for studies of diagnostic tests on patients known or suspected to have diabetes and a foot infection...

Calcaneus osteomyelitis is a rare infection in newborns. Invasive procedures, prematurity and low birth wight are some causative factors. The clinical signs may be mild. We report a neonate with calcaneous osteomyelitis which was secondary to a Guthrie test sample. She was admitted to hospital with swelling, redness and increased temperature on her heel. Superficial tissue ultrasound showed fluid collection with heavy content was observed on the posterior of the right foot. Puncture and drainage was performed and methicillin-susceptible Staphylococcus aureus was isolated from the drainage culture...

Gait imagery and gait observation can boost the recovery of locomotion dysfunctions; yet, a neurologically justified rationale for their clinical application is lacking as much as a direct comparison of their neural correlates. Using functional magnetic resonance imaging, we measured the neural correlates of explicit motor imagery of gait during observation of in-motion videos shot in a park with a steady cam (Virtual Walking task). In a 2 × 2 factorial design, we assessed the modulatory effect of gait observation and of foot movement execution on the neural correlates of the Virtual Walking task: in half of the trials, the participants were asked to mentally imitate a human model shown while walking along the same route (mental imitation condition); moreover, for half of all the trials, the participants also performed rhythmic ankle dorsiflexion as a proxy for stepping movements...

BACKGROUND: Functional magnetic resonance imaging (fMRI) is a promising method for quantifying brain recovery and investigating the intervention-induced changes in corticomotor excitability after stroke. This study aimed to evaluate cortical reorganization subsequent to virtual reality-enhanced treadmill (VRET) training in subacute stroke survivors. METHODS: Eight participants with ischemic stroke underwent VRET for 5 sections per week and for 3 weeks. fMRI was conducted to quantify the activity of selected brain regions when the subject performed ankle dorsiflexion...

BACKGROUND: Disease-related foot pathology is recognised to have a significant impact on mobility and functional capacity in the majority of patients with rheumatoid arthritis (RA). The forefoot is widely affected and the metatarsophalangeal (MTP) joints are the most common site of symptoms. The plantar plates are the fibrocartilaginous distal attachments of the plantar fascia inserting into the five proximal phalanges. Together with the transverse metatarsal ligament they prevent splaying of the forefoot and subluxation of the MTP joints...
