Kyle Patrick, Luke Donovan
In-shoe plantar pressure systems are commonly used in clinical and research settings to assess foot function during functional tasks. Recently, Tekscan® has updated their F-Scan® in-shoe plantar pressure system; however, this system's test-retest reliability has not been established. Therefore, the purpose of this study was to determine the test-retest reliability of the F-Scan® 7 system in recreationally active individuals during treadmill walking. Seventeen healthy adults completed 2 sessions of treadmill walking...

BACKGROUND: The 3-dimensional nature of adult acquired flatfoot deformity can be challenging to characterize using radiographs. We tested the hypothesis that measurements on weight-bearing (WB) cone-beam computed tomography (CT) images were more useful for demonstrating the severity of the deformity than non-weight-bearing (NWB) measurements. METHODS: We prospectively enrolled 12 men and 8 women (mean age, 52 years; range, 20 to 88 years) with flexible adult acquired flatfoot deformity...

INTRODUCTION: Flexible flatfoot is common amongst children, although treatment is rarely indicated. The calcaneo-stop procedure has been reported to be effective in short-term studies. We aim to evaluate the long-term outcomes of the calcaneo-stop procedure in the treatment of flexible flatfoot in children. MATERIAL AND METHODS: Twenty-six calcaneo-stop procedures performed between 1995 and 2006 on 13 patients were evaluated clinically and using photopodoscopy, and the FAOS questionnaire was applied for both feet...

Primary synovial chondromatosis is a benign neoplastic process, occurring mostly in large joints, more rarely in tendon sheaths, and extremely uncommonly in bursae. We describe a patient with primary synovial chondromatosis arising in the fourth intermetatarsal bursa. Knowledge of the bursal anatomy of the forefoot, and of characteristic imaging findings and the pathogenesis of synovial chondromatosis, is essential in including this uncommon entity in the differential when occurring in unusual locations.

BACKGROUND: No criteria, including pre-amputation vascular diagnostic thresholds, have been established to reliably predict healing versus non-healing following minor lower extremity amputations. Thus, the goal of our study was to identify clinical factors, including non-invasive vascular laboratory measures, associated with wound healing following toe, forefoot, and midfoot amputations. METHODS: We retrospectively examined records of patients receiving elective toe, forefoot, or midfoot amputation at our institution over a 5-year span (2010-2015)...

The foot is rarely the focus of osteoid osteoma, and only a few of those cases are related to the fifth metatarsal. The present case demonstrates that atypical symptoms with suspicious findings on plain radiographs that are not associated with trauma must be analyzed carefully to determine the nature of the lesion and perform the precise treatment to obtain and sustain the cure. A 29-year-old man presented to the outpatient clinic with a 2-year history of chronic pain in the lateral aspect of his left forefoot...

BACKGROUND: Congenital vertical talus is a rare foot anomaly characterized by a prominent calcaneus and rigid forefoot dorsiflexion. While congenital vertical talus has been associated with anomalies such as trisomy 18, myelomeningocele and arthrogryposis, postnatal series have reported cases of isolated congenital vertical talus. OBJECTIVE: The purpose of our study was to determine the incidence of isolated congenital vertical talus prenatally and identify the most common anomalies associated with this finding...

Wen-Ming Chen, Sung-Jae Lee, Peter Vee Sin Lee
Use of finite element (FE) foot model as a clinical diagnostics tool is likely to improve the specificity of foot injury predictions in the diabetic population. Here we proposed a novel workflow for rapid construction of foot FE model incorporating realistic geometry of metatarsals encapsulated into lumped forefoot's soft tissues. Custom algorithms were implemented to perform unsupervised segmentation and mesh generation to directly convert CT data into a usable FE model. The automatically generated model provided higher efficiency and comparable numerical accuracy when compared to the model constructed using a traditional solid-based mesh process...

BACKGROUND: Orthoses are commonly prescribed to children with cerebral palsy (CP) in order to provide foot correction and to improve ambulatory function. Immediate effects of ankle foot orthosis (AFOs) have been investigated, but long term kinematic effects are lacking clinical evidence. OBJECTIVE: To determine changes in pediatric patients with Cerebral Palsy's 3D ankle and foot segment motion between initial, and follow up visits (18 month average time differences) in both barefoot gait and gait with their ankle foot orthotic (AFO)...

Treatment of idiopathic clubfoot has shifted from extensive surgical release to conservative Ponseti method; however, randomized prospective trials to compare both methods are lacking. The goal of this study was to compare the long-term results of Ponseti method with those of surgery in terms of morphology, function, X-rays, overall health and gait. In 2001, a single center, prospective, randomized, and controlled trial with a parallel design was started. Twenty-four feet of 15 patients were randomly assigned to two groups: 12 feet each to a Ponseti and surgical group...

INTRODUCTION: Infected diabetic foot ulcers are the leading cause of lower limb amputation. This study evaluated the ability of in-shoe exoskeletons to redirect forces outside of body and through an exoskeleton as an effective means of offloading plantar pressure, the major contributing factor of ulceration. METHODS: We compared pressure in the forefoot and hind-foot of participants (n = 5) shod with novel exoskeleton footwear. Plantar pressure readings were taken during a 6-m walk at participant's self-selected speed, and five strides were averaged...

BACKGROUND: The effects of age and speed on foot and ankle kinematics in gait studies using foot models are not fully understood, whereas this can have significant influence. We analyzed these variables with the 4-segment Oxford foot model. METHODS: Twenty-one healthy subjects (aged 20-65 years) were recruited for gait analysis. The effect of speed on foot and ankle kinematics was assessed by comparing results during slow walking and fast walking. To assess the effect of age, a group of 13 healthy young adults (aged 20-24 years) were compared with a group of 8 older adults (aged 53-65 years)...

BACKGROUND: Due to the high incidence of forefoot ulcerations with associated osteomyelitis, there has been an increased demand for partial ray amputations. In order to ensure complete removal of infected metatarsal bone, a clean margin amount is chosen based on the surgeon's intraoperative visual subjective evaluation. The margin is resected and sent to pathology. Currently the literature shows positive proximal margin rates of 35-40%. The purpose of this study was to reduce the rate of positive proximal margins by effectively resecting all infected bone using pre-operative MRI measurements with an added resection margin...
