PURPOSE OF THE STUDY Accurate radiographic measurements are crucial in treating hallux valgus (HV). This three-dimensional deformity should not be evaluated from one joint on one plane. However, in practice, surgeons measure the deformity only on transverse dorsoplantar radiographs. We determined the amount of error associated with positioning the foot incorrectly on radiographs. MATERIAL AND METHODS To simulate incorrect positions of the foot in radiographic evaluation, we designed an angled device that can move in transverse and frontal plane...

The development of the human foot is crucial for motor learning in children and adolescents as it ensures the basic requirements for bipedal locomotion and stable standing. Although there is an ongoing debate of the advantages and disadvantages of early and permanent footwear use, the influence of regular barefootness on foot characteristics in different stages of child development has not been extensively evaluated. A multicenter epidemiological study was conducted to compare the foot morphology between habitually barefoot children and adolescents (N = 810) to age-, sex- and ethnicity-matched counterparts that are used to wearing shoes...

BACKGROUND: A high incidence of dorsomedial cutaneous nerve (DMCN) damage in hallux valgus surgery has been reported. Identification of the vein around 1st metatarsal head is reported to be helpful to reduce the DMCN damage during surgery. The near-infrared (NIR) vascular imaging system, the VeinViewer(®) Flex, projects the vein onto the skin. The purpose of this study was to investigate the difference of the vein course between normal and hallux valgus foot using the VeinViewer(®) Flex, and to validate that the DMCN was accompanied with its vein...

BACKGROUND: Limited data are available comparing the results of lateral sesamoidectomy and medial sesamoidectomy for the treatment of fractures recalcitrant to nonoperative treatment interventions. The hypothesis of this study was that sesamoidectomy for either lateral or medial sesamoid fractures would not change radiographic alignment of the first ray given the use of identical reconstruction of the plantar plate, intersesamoid ligament, and plantar ligament complex at the time of surgery...

INTRODUCTION: Some clinicians advocate stretching to prevent muscle cramps. It is unknown if static or proprioceptive neuromuscular facilitation (PNF) stretching increases cramp threshold frequency (TFc ), a quantitative measure of cramp susceptibility. METHODS: Fifteen individuals completed this randomized, counterbalanced, cross-over study. We measured passive hallux ROM and then performed three minutes of either static stretching, PNF stretching (hold-relax-with agonist contraction), or no stretching...

Ward M Glasoe, Michael W Rodriguez, Kara E Pioske
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)...

BACKGROUND: High-heeled shoes (high heels) are frequently worn by many women and form an important part of female gender identity. Issues of explicit and implicit compulsion to wear high heels have been noted. Previous studies and reviews have provided evidence that high heels are detrimental to health. However, the evidence base remains fragmented and no review has covered both the epidemiological and biomechanical literature. In addition, no review has considered the psychosexual benefits that offer essential context in understanding the public health challenge of high heels...

We report a case of an 18-year-old woman, with bilateral acute inflammatory pain on the hip area, during the premenstrual period, and progressive increase in volume and rigidity of both hips. Bilateral exuberant soft tissue calcifications were present on the radiographic exams, and the patient also presented with bilateral short-length hallux valgus. A heterozygous mutation in the protein kinase domain of ACVR1 gene was found, allowing the diagnosis of fibrodysplasia ossificans progressive. Due to the relation between the disease flares and the premenstrual period, the patient was put into a chemically induced amenorrhea, with no new inflammatory crises since...

BACKGROUND: Postoperative transfer metatarsalgia is a common complication after hallux valgus surgeries. Shortening of the first metatarsal is traditionally thought to be the primary cause of it. However, we speculate the abnormal loading pattern during gait is the real reason. This study is to determine specific differences in the loading patterns between reconstructive hallux valgus (HV) feet with and without postoperative transfer metatarsalgia, so as to find risky loading characteristics of this complication...

The irreducible dislocation of the hallux interphalangeal joint is an infrequent condition and only a few cases have been described. It presents as dorsal dislocation with interposition of the sesamoid bone, which has the possibility of being radiologically undetectable. We present the case of a 29 year-old patient who, after a sports trauma sustained a hallux interphalangeal dislocation that went unnoticed for eight days. Since, closed reduction was not possible, as occurred in several cases reported in the literature, open reduction was performed through a dorsal incision...

PURPOSE: We report 3- to 8-year follow-up results for the first tarsometatarsal joint derotational arthrodesis. METHODS: A total of 70 patients (88 feet) with symptomatic flexible hallux valgus were operated between 2003 and 2009. In all, 66 patients (94.3%) with 84 (95.5%) feet were enrolled in retrospective analysis; of those, 58 (87.9%) patients with 76 (90.5%) feet were followed for a mean of 5.1 (range: 3.0-8.3) years. Preoperative, 6 week postoperative, and late follow-up weightbearing radiographs were evaluated along with clinical examination and questionnaires...

BACKGROUND AND AIMS: Many kinds of insoles and pads are commonly used as a conservative treatment of metatarsalgia. However, earlier studies of insole treatment provide contradictory results, and the natural progression of metatarsalgia is still unknown. The aims of this study were to (1) determine whether simple custom-made metatarsal pad insoles reduce pain and improve functional ability, (2) find out patients' satisfaction with padding treatment, and (3) investigate predisposing factors for metatarsalgia...

REVIEW
Naohiro Shibuya, Thomas S Roukis, Daniel C Jupiter
The hypermobility theory of the first ray is the reason for the popularization of procedures such as the modified Lapidus procedure involving arthrodesis of the first tarsal-metatarsal joint for correction of hallux valgus deformity. Although many studies have involved motion of the first ray in hallux valgus patients, the presence and clinical significance of hypermobility in the first ray remains controversial. We performed a systematic review and meta-analysis to evaluate the difference in the first ray range of motion between patients with or without hallux valgus deformity...

The purpose of this study was to determine the intra and inter-assessor repeatability of a modified Rizzoli Foot Model for analysing the foot kinematics of ballet dancers. Six university-level ballet dancers performed the movements; parallel stance, turnout plié, turnout stance, turnout rise and flex-point-flex. The three-dimensional (3D) position of individual reflective markers and marker triads was used to model the movement of the dancers' tibia, entire foot, hindfoot, midfoot, forefoot and hallux. Intra and inter-assessor reliability demonstrated excellent (ICC ≥ 0...

BACKGROUND: The Footscan® platform system is one of the most commonly used clinical tools for the measurement of the foot pressure. The present study was designed to assess the repeatability of the system and identify the range of loading parameters observed in the normal foot. METHODS: Measurements were collected from 32 healthy participants, 15 females and 17 males, twice at an interval of 1 week. Peak pressure (PP), contact time (CT), contact area (CA), pressure-time integral (PTI), and maximum force (MaF) were recorded; these parameters were investigated in 10 areas of the foot: medial heel, lateral heel, midfoot, first to fifth metatarsals, hallux, and toes 2-5...

BACKGROUND: Although accumulative evidence exists that support the applicability of multi-segmental foot models (MFMs) in evaluating foot motion in various pathologic conditions, little is known of the effect of aging on inter-segmental foot motion. The objective of this study was to evaluate differences in inter-segmental motion of the foot between older and younger adult healthy females during gait using a MFM with 15-marker set. METHODS: One hundred symptom-free females, who had no radiographic evidence of osteoarthritis, were evaluated using MFM with 15-marker set...
