Posterior tibial tendon dysfunction is often coupled with various degrees of hindfoot valgus and equinus. Preoperative planning is essential to appropriate procedure choice and surgical efficiency. The purpose of the present study was to assess the anatomy at the harvest site for flexor digitorum longus tendon transfer, specifically at the master knot of Henry. Thirty fresh-frozen below-the-knee cadavers were used for dissection. A standard anatomic approach was performed for posterior tibial tendon debridement and flexor digitorum longus tendon transfer...

BACKGROUND: Several studies have identified the association between ambient temperature and mortality; however, several features of temperature behavior and their impacts on health remain unresolved. We obtain daily counts of nonaccidental all-cause mortality data in the elderly (65 + years) and corresponding meteorological data for Melbourne, Australia during 1999 to 2006. We then characterize the temporal behavior of ambient temperature development by quantifying the rates of temperature change during periods designated by pre-specified windows ranging from 1 to 30 days...

: Ankle fractures are a common injury treated by orthopaedic surgeons. The distal tibiofibular syndesmosis can be injured during these fractures as well as in isolation. They pose a significant challenge with regard to the diagnosis of instability as well as evaluating reduction after fixation. Multiple studies have demonstrated that traditional radiographic analysis fails to accurately identify syndesmotic diastasis, instability, or malreduction. Ankle arthroscopy has been proposed as an alternative way to evaluate the syndesmosis...

: First metatarsophalangeal joint arthritis can stem from a biomechanical imbalance as in hallux abducto valgus, metabolic arthritidies such as rheumatoid or gout, and even in posttraumatic cases. Advanced arthritis in the foot and ankle can often become debilitating. Surgical intervention is often necessary. Revision of failed first metatarsophalangeal joint arthroplasty is often in the setting of bony erosion and lysis, cystic changes, and loss of bone stock. In this article, we describe first metatarsophalangeal distraction arthrodesis technique using tricortical calcaneus autograft with the aim of simplifying donor site graft harvesting and decreasing donor site morbidity while attaining successful osseous union...

In this qualitative study, the process of developing a politicized identity around diet was explored through a social psychological lens. Applying one of the most influencial models of group identity development proposed by Cross (1978) in which an "encounter" experience spurs an awakening into a politicized identity, we asked 36 participants who followed alternative diets due to political reasons to describe their unique encounter experiences that brought them to their politicized awakening. Their self-identified diets included pescetarian, vegetarian, vegan, raw, non-GMO/organic, and reduced meat consumption...

BACKGROUND: The "tibiofibular line" is a new axial computed tomography parameter for assessing syndesmosis reduction, which references the flat anterolateral surface of the fibula and anterolateral tibial tubercle. These same bony landmarks are easily visualized via a lateral approach to the fibula. This cadaveric study assessed the practical aspects of measuring the tibiofibular line intraoperatively. METHODS: Three observers simulated the tibiofibular line using operative rulers in 3 measurement series utilizing 10 cadaveric specimens: intact syndesmosis, syndesmosis reduction, and fixation after application of lateral plate and screws to the fibula, and post syndesmosis reduction and fixation without plate and screws...

OBJECTIVES: Research has shown greater mobility limitations among women than men. We aimed to examine (a) gender differences in the use of canes for mobility and (b) what factors contribute to these differences under the frameworks of the disablement model and the Theory of Planned Behavior. METHOD: Using National Health and Aging Trends Study data, we estimated hierarchical logistic regression models to predict the likelihood of cane use among older adults who completed performance-based measures (n = 5,503)...

PURPOSE: To quantitatively assess the advantages of energy-layer specific dynamic collimation system (DCS) versus a per-field fixed aperture for spot scanning proton therapy (SSPT). METHODS: Five brain cancer patients previously planned and treated with SSPT were replanned using an in-house treatment planning system capable of modeling collimated and uncollimated proton beamlets. The uncollimated plans, which served as a baseline for comparison, reproduced the target coverage and organ-at-risk sparing of the clinically delivered plans...

: Total ankle replacement (TAR) is a viable alternative to ankle fusion in certain patients with end-stage ankle arthritis. Despite the importance of understanding alignment and movement of the prosthesis, there is no standardized radiographic method for evaluating the position and movement of the INBONE 2 prosthesis. The aims of this study were to describe a radiographic measurement protocol for INBONE 2 for clinical practice and research while determining the interobserver and intraobserver reliability using standard weightbearing radiographs...

Total ankle replacement studies have focused on reporting complications that are directly observed clinically or radiographically, including wound problems, technical errors, implant loosening, subsidence, infection, bone fractures, and heterotopic ossification. However, patients can still experience unresolved pain even when these problems have been ruled out. We initiated a study to more clearly define the relative risk of injury to the anatomic structures in the posterior ankle during total ankle replacement using a third-generation implant system...

The mammalian brain has evolved in close synchrony with the natural environment; consequently, trends toward disengagement from natural environments in today's industrialized societies may compromise adaptive neural responses and lead to psychiatric illness. Investigations of rodents housed in enriched environments indicate enhanced neurobiological complexity; yet, the origin of these stimuli, natural vs. manufactured, has not been sufficiently explored. In the current study, groups of rats were exposed to one of three environments: (1) a standard environment with only food and water, (2) an artificial-enriched environment with manufactured stimuli and (3) a natural-enriched environment with natural stimuli...

BACKGROUND: Among patients with systemic sclerosis (SSc), early recognition of potentially life-threatening organ involvement is critical. Because prompt recognition of early signs of organ involvement can dramatically alter a patient׳s outcome, it is crucial that patients and primary care providers (PCPs) recognize these symptoms. We conducted a survey of patients with SSc regarding their perceptions of the quality of their primary care, and whether or not they perceive the quality of their primary care to be impaired by their scleroderma diagnosis...
