BACKGROUND: Understanding the concept of kinematic coupling is essential when selecting the appropriate therapeutic strategy and grasping mechanisms for the occurrence of injuries. A previous study reported that kinematic coupling between the rearfoot and shank during running and walking were different. However, because foot mobility involves not only the rearfoot but also the midfoot or forefoot, kinematic coupling is likely to occur among the rearfoot, midfoot, and forefoot segments...

A 55-year-old man with poliomyelitis presented with a plantarflexed foot and painful ulceration of the sub-first metatarsophalangeal joint present for many years. A two-stage procedure was performed to bring the foot to 90°, perpendicular to the leg, and resolve the ulceration. The first stage corrected only soft-tissue components. It involved using a hydrosurgery system to debride and prepare the ulcer, a unilobed rotational skin plasty to close the ulcer, and a tendo Achillis lengthening to decrease forefoot pressure...

Background: Foot morphology has received increasing attention from both biomechanics researches and footwear manufacturers. Usually, the morphology of the foot is quantified by 2D footprints. However, footprint quantification ignores the foot's vertical dimension and hence, does not allow accurate quantification of complex 3D foot shape. Methods: The shape variation of healthy 3D feet in a population of 31 adult women and 31 adult men who live in Belgium was studied using geometric morphometric methods...

BACKGROUND: Third generation total talar prostheses (TTPs) are viable options for talar avascular necrosis (AVN) in the absence of neighboring joint pathology. The use of modern three-dimensional (3D) printing allows the production of custom implants that exactly mimic the patient's anatomy. The aim of this study is to determine the accuracy of 3D printing in reproducing a synthetic talus and, in doing so, restoring more normal anatomical relationships. We hypothesize that this mode of replication will restore and maintain normal radiographic alignment of the ankle, subtalar, and forefoot joints in the setting of talar AVN...

BACKGROUND: Tibialis posterior tendon transfer is performed when loss of dorsiflexion has to be compensated. We evaluated the circumtibial (CT), above-retinaculum transmembranous (TMAR), and under-retinaculum transmembranous (TMUR) transfer gliding resistance and foot kinematics in a cadaveric foot model during ankle range of motion (ROM). METHODS: Eight cadaveric foot-ankle distal tibia specimens were dissected free of soft tissues on the proximal end, applying an equivalent force to 50% of the stance phase to every tendon, except for the Achilles tendon...

BACKGROUND: Foot posture is a risk factor for some lower limb injuries, however the underlying mechanism is not well understood. Plantar pressure analysis is one technique to investigate the interaction between foot posture and biomechanical function of the lower limb. RESEARCH QUESTION: The aim of this review was to investigate the relationship between foot posture and plantar pressure during walking. METHODS: A systematic database search was conducted using MEDLINE, CINAHL, SPORTDiscus and Embase to identify studies that have assessed the relationship between foot posture and plantar pressure during walking...

BACKGROUND: The ideal treatment for comminuted intraarticular calcaneal fractures is still debated. Open reduction and internal fixation (ORIF) is the most popular surgical procedure; however, wound complications, implant choice, and infection remain major concerns. This study aimed to demonstrate the results of an innovative, minimally invasive surgical procedure, namely, a closed reduction technique using large-diameter Steinmann pins and percutaneous calcaneoplasty using injectable calcium sulfate cement (MIIG X3, Wright Medical Technology, Inc...

The Hereditary Spastic Paraplegias (HSP) are a group of heterogeneous disorders with a wide spectrum of underlying neural pathology, and hence HSP patients express a variety of gait abnormalities. Classification of these phenotypes may help in monitoring disease progression and personalizing therapies. This is currently managed by measuring values of some kinematic and spatio-temporal parameters at certain moments during the gait cycle, either in the doctor´s surgery room or after very precise measurements produced by instrumental gait analysis (IGA)...

There are currently no longitudinal data describing the pre- and postoperative postural regulation and stability of patients with anterior cruciate ligament (ACL) damage. Therefore, the aim of this study was to evaluate postural regulation and stability prior to and during rehabilitation following surgery of the ACL. Fifty-four physically active subjects (age: 30.5±10.9 years, 29 male subjects) were examined with the Interactive Balance System pre-, 6, and at 12 weeks following surgical reconstruction of the ACL using a hamstring tendon graft...

Fusion of the first metatarsophalangeal joint (MTPJ) is the reference standard surgery for significant hallux rigidus. A number of different techniques for first MTPJ fusion have been reported. We describe our technique of first MTPJ fusion using cup and cone reamers for joint surface preparation and 2 crossed cannulated screws for fixation. To the best of our knowledge, this is the single largest series using this technique. The present study reports on a single-surgeon, consecutive series of 166 consecutive cases in 147 patients who had undergone first MTPJ fusion...

OBJECTIVE: Ischemic heel ulcerations are generally thought to carry a poor prognosis for limb salvage. We hypothesized that patients undergoing infrapopliteal revascularization for heel wounds, either bypass or endovascular intervention, would have lower wound healing rates and amputation-free survival than patients with forefoot wounds. METHODS: A retrospective chart review was performed of patients who presented between 2006 and 2013 to our institution with ischemic foot wounds and infrapopliteal arterial disease and underwent either pedal bypass or endovascular tibial artery intervention...

INTRODUCTION: Since pregnant women may have potentially greater difficulty maintaining balance, their stability has been investigated by some researchers. However, there is no consensus considering the results. The purpose of our investigation was to compare all the experimental studies focusing on the analysis of gait that have been conducted over the last years to assess their methodological issues and changes induced by pregnancy. METHODS: The PRISMA Guidelines incorporating a risk of bias and strength of recommendations were used as a methodological template for this review...

The study sought to investigate whether an orthotic stiletto could modulate the pressure and comfort under the forefoot, arch and heel that stiletto wearers experience. Twenty-two women participated. We measured the peak pressure and pressure-time integral for orthotic stilettos with built-in metatarsal pad, heel cup and arch support; standard stilettos without inlays; and trainers. Comfort was recorded during 3x3 working days. The orthotic stiletto exhibited lower metatarsal head1 (MTH) and MTH2+3 and heel pressures than the standard stiletto (p < ...

CLINICAL ISSUE: Both benign and malignant tumours are encountered in the foot and ankle. Due to their rarity, however, diagnosis is often uncertain. Usual criteria such as tumour size, invasiveness or pain fail to differentiate benign from malignant neoplasias. STANDARD RADIOLOGICAL METHODS: Plain radiography and-due to the complex foot anatomy-CT are important in the diagnostic evaluation of primary bone tumours. In the case of soft tissue tumours, ultrasonography is used to identify ganglion cysts...

This study aimed to investigate the effects of varying midsole hardness on center of pressure (COP) and perceived stability during basketball-specific tasks, as well as the correlation between COP and perception measurements. Twenty male basketball players performed 45° cutting and lay-up while wearing basketball shoes with soft and hard midsoles. COP trajectories were obtained from the Pedar insole system. Stability perceptions at the forefoot and rearfoot were assessed using 150-mm visual analogue scales (VAS)...

Ankle power dominates forward propulsion of gait, but midfoot power generation is also important for successful push off. However, it is unclear if midfoot power generation increases or stays the same in response to propulsive activities that induce larger external loads and require greater ankle power. The purpose of this study was to examine ankle and midfoot power in healthy adults during progressively more demanding functional tasks. Multi-segment foot motion (tibia, calcaneus, forefoot) and ground reaction forces were recorded as participants (N=12) walked, ascended a standard step, and ascended a high step...

Infections of the skin and soft tissues (SSTI) are clinical entities with variable presentations, causes, and levels of clinical severity. They are frequent in emergency departments. The most common pathogen in the Western World is Staphylococcus aureus . SSTI may provide a hint to underlying pathologies such as diabetes and other states of immune compromise. Here we present a 41-year-old non-diabetic male patient with pain and swelling of the left forefoot but not any recent trauma. Microbiology identified streptococci...
