Previous studies have successfully used the longitudinal arch angle (LAA) to assess foot posture, but the measurement consistency and ability of the LAA to predict dynamic foot posture during activity in a variety of foot types have not been evaluated. The purpose of this study was to determine the reliability of the LAA as well as if the clinical method of assessing the LAA could be used to predict the LAA at midstance during walking for supinated, normal, and pronated foot types. The Arch Height Ratio was used to select 35 participants with 12 supinated, 46 normal, and 12 pronated feet...

In this report we present two cases of gunshot injury related midfoot defects, reconstructed with a chimeric partial scapula and latissimus dorsi muscle flap and short perforator-based skin flap. The first case, a 14 years old male, had 10 × 8 cm medial plantar and 6 × 4 cm dorsal foot defects and the second case, a 55 years old female, had only 8 × 6 cm dorsal foot defect. In both cases the defects were associated with fractures, one with lateral cuneiform and cuboid with 90% bone loss and the other with navicular bone, respectively...

Osteoarticular TB around the tarsal navicular is a chronic, uncommon condition affecting the midfoot, which causes significant morbidity to the patient. Tuberculosis around the tarsal navicular is rarely described in the literature. A series of three cases - two involving the talo-navicular joint and one involving the naviculo-cuneiform joint is described. Biopsy was used in all the cases for achieving diagnosis. All patients had good to fair outcome following medical management with anti-tubercular therapy...

The scaphoid is biomechanically and clinically of great importance for function of the wrist. In the literature, its anatomy and biomechanics are clearly underrepresented as well as underestimated. In the following review the scaphoid will be presented in more detail, according to recent information and findings. Not only will the origin of the name and the history of previous names, such as cotyloid or navicular, be introduced, but also for the first time in medical literature the significant phylogeny and ontogeny of the scaphoid will be shown...

PURPOSE: The optimal management of undisplaced scaphoid fractures remains controversial. A systematic review was conducted to assess the outcomes of acute, undisplaced scaphoid fractures managed with cast immobilization versus percutaneous or miniopen screw fixation in terms of time to return to work (RTW), time to union, and morbidity. METHODS: PubMed MEDLINE, Ovid MEDLINE, EMBASE, SCOPUS, and Cochrane electronic databases were searched over the period 1974 to 2015...

Positron emission tomography (PET) is a highly sensitive, noninvasive imaging technique for quantifying biological functions of tissues. However, at the time of this study, PET imaging applications had not been reported in the horse. The aim of this exploratory study was to determine whether a portable high-resolution PET scanner could be used to image the equine distal limb. Images of the front feet and fetlocks of three research horses, with known lesions localized to the distal front limbs, were acquired under general anesthesia after administration of (18) F-fluorodeoxyglucose ((18) F-FDG), with doses ranging from 1...

In-vitro and invasive in-vivo studies have reported relatively independent motion in the medial and lateral forefoot segments during gait. However, most current surface-based models have not defined medial and lateral forefoot or midfoot segments. The purpose of the current study was to determine the reliability of a seven segment foot model that includes medial and lateral midfoot and forefoot segments during walking gait. Three-dimensional positions of marker clusters located on the leg and six foot segments were tracked as ten participants completed five walking trials...

BACKGROUND: An osteochondral lesion of the navicular bone in the foot is rare. Differentiation from a stress fracture is difficult, since both lesions usually present as vague pain in the midfoot in active young adults. However, the typical location differs. SPECT-CT allows an etiological diagnosis to be made. As management differs for the two lesions, a correct diagnosis is important. CASE DESCRIPTION: A 19-year-old male athlete had pain in the dorsal right midfoot on weight-bearing...

This study is to draw attention to a relatively common anatomical anomaly and its possible operative treatment in dancers. The accessory navicular, or os tibiale externum, is an accessory bone on the medial side of the navicular of the foot at the insertion of the posterior tibial tendon (PTT). It can cause obvious hyperpronation, medial foot pain, and a limited and painful relevé in dancers. To the best of our knowledge, this is the first report on the operative treatment of the accessory navicular exclusively in dancers...

Synovitis is usually observed before loss of articular function in rheumatoid arthritis (RA). In addition to the synovium and according to the "Inside-Outside" theory, bone compartment is also involved in RA pathogenesis. Then, we investigated time dependent articular bone loss and prediction of early bone loss to late arthritis severity on the rat adjuvant-induced arthritis (AIA) model. Lewis female rats were longitudinally monitored from arthritis induction (day 0), with early (day 10) and late (day 17) steps...

Sexual estimation is fundamental to reconstruct the biological profile of individuals, but postdepositional factors can alter the resistance of the bones, thereby preventing accurate diagnosis especially when the skull and the pelvis are absent. Navicular bones are usually well preserved in archeological and forensic contexts and can a good alternative to discriminate sex. On the basis of these aspects, the present investigation analyzed the sexual dimorphism in 231 pairs of navicular bones from documented contemporary collections from Spain...

Erosive bony lesions are radiographic findings where localized bone resorption and cortical line breakage occurs. One less common cause of bone erosions is arteriovenous malformations (AVMs). This should always be included in the differentials for foot pain.A 33-year-old gentleman presented with a 5-year history of chronic left foot pain. Clinical examination was unremarkable. Magnetic resonance imaging (MRI) and computerized tomography demonstrated erosive bone changes in the navicular, the intermediate and lateral cuneiforms bones and their corresponding metatarsal bases...

BACKGROUND: Positional MRI (pMRI) allows for three-dimensional visual assessment of navicular position. In this exploratory pilot study pMRI was validated against a stretch sensor device, which measures movement of the medial plantar arch. We hypothesized that a combined pMRI measure incorporating both vertical and medial displacement of the navicular bone induced by loading would be correlated with corresponding stretch sensor measurements. METHODS: 10 voluntary participants were included in the study...

Sterilized allografts may be less resistant to collapse and prone to nonunion leading to loss of correction in open wedge osteotomies. These adverse events usually occur at early time points (i.e., < 9 months postoperatively). The goal of this study was to compare sterilized allografts to autologous grafts in respect to secondary loss of hindfoot alignment and graft incorporation after lateral calcaneal lengthening osteotomies.Fifty patients (22 F/ 28 M, age: 16-69 years) who had undergone 50 lateral calcaneal lengthening osteotomies for adult flatfoot deformity were included in this retrospective study...

The longitudinal arch is a unique characteristic of the human foot, yet the timing and pattern of its evolution remain controversial, in part due to the disagreement among researchers over which skeletal traits are the best indicators of its presence or absence. The small size of the human navicular tuberosity has previously been linked to the presence of a longitudinal arch, implying that the large tuberosity of early hominins such as Australopithecus afarensis reflects a flat foot. However, this hypothesis is at odds with other evidence of pedal form and function, such as metatarsal, tarsal, and footprint morphology, which show that a longitudinal arch was probably present in A...

The tarsal bones articulate with each other and demonstrate complicated kinematic characteristics. The in vivo motions of these tarsal joints during normal gait are still unclear. Seven healthy subjects were recruited and fourteen feet in total were tested in the current study. Three dimensional models of the tarsal bones were first created using CT scanning. Corresponding local 3D coordinate systems of each tarsal bone was subsequently established for 6DOF motion decompositions. The fluoroscopy system captured the lateral fluoroscopic images of the targeted tarsal region whilst the subject was walking...

OBJECTIVE: To assess a classification system for midfoot injury that was based on the characteristics of the foot malunion and to evaluate the suggested treatment strategies. METHODS: This retrospective review of data from patients with posttraumatic midfoot malunion categorized each foot deformity into one of three types based on the foot arch and then separated these categories into one of three subtypes based on the forefoot deformity. According to the types of malunion, fascio-cutaneous flap, osteotomy, joint arthrodesis or realignment was used to correct the deformity...
