James M Gerrard, Daniel R Bonanno
Increasing preferred step rate during running is a commonly used strategy in the management of running-related injuries. This study investigated the effect of different step rates on plantar pressures during running. Thirty-two healthy runners ran at a comfortable speed on a treadmill at five step rates (preferred, ±5%, and ±10%). For each step rate, plantar pressure data were collected using the pedar-X in-shoe system. Compared to running with a preferred step rate, a 10% increase in step rate significantly reduced peak pressure (144...

Stress fractures of the foot and ankle are a commonly encountered problem among athletes and individuals participating in a wide range of activities. This illustrated review, the second of two parts, discusses site-specific etiological factors, imaging appearances, treatment options, and differential considerations of stress fractures of the foot and ankle. The imaging and clinical management of stress fractures of the foot and ankle are highly dependent on the specific location of the fracture, mechanical forces acting upon the injured site, vascular supply of the injured bone, and the proportion of trabecular to cortical bone at the site of injury...

Three-dimensional (3-D) printing offers many potential advantages in designing and manufacturing plating systems for foot and ankle procedures that involve small, geometrically complex bony anatomy. Here, we describe the design and clinical use of a Ti-6Al-4V ELI bone plate (FastForward™ Bone Tether Plate, MedShape, Inc., Atlanta, GA) manufactured through 3-D printing processes. The plate protects the second metatarsal when tethering suture tape between the first and second metatarsals and is a part of a new procedure that corrects hallux valgus (bunion) deformities without relying on doing an osteotomy or fusion procedure...

BACKGROUND: Traumatic hallux valgus is an increasingly common injury in the athletic population and represents a unique variant of turf toe. Failure to appropriately recognize and treat these injuries can lead to continued pain, decreased performance, progressive deformities, and ultimately degeneration of the hallux metatarsophalangeal joint. Limited literature currently exists to assist in the diagnosis, management, and operative treatment. METHODS: Nineteen patients were reviewed in this series, including 12 National Football League, 6 college, and 1 high school player who was a college prospect...

BACKGROUND: Recurrent pain and deformity following forefoot surgery can cause significant patient disability. In patients with rheumatoid arthritis, first metatarsophalangeal (MTP) joint arthrodesis with lesser metatarsal head resections-termed the rheumatoid forefoot reconstruction-has been shown to be a reliable operation for pain relief and deformity correction. Limited data, however, have been published on outcomes of the same forefoot reconstruction operation in the nonrheumatoid patient...

Polydactyly is a phenotypically and genetically highly heterogeneous limb malformation with preaxial and postaxial subtypes and subtypes A and B. Most polydactyly entities are associated with GLI3 mutation. We report on 10 affected individuals from a large Pakistani kindred initially evaluated as a possible new condition. The phenotype is postaxial polydactyly types A and B associated with zygodactyly, postaxial webbing of toes and additional features not previously reported for isolated polydactyly such as camptodactyly, hypoplasia of third toe, and wide space between hallux and second toe...

The authors present a 43-year-old woman with a yellow, swollen toe nail of the right foot. This nail was lesioned 20 years before. The proximal nail fold of the right hallux was erythematous and indurated. The medial half of the nail was thickened and yellowish, sharply demarcated from the unaffected half. This aspect is typical for onychomatricoma.

Cannabis arteritis (CA) is a major and underdiagnosed cause of peripheral arterial disease in young patients. A 34-year-old man, daily smoker of 20 cigarettes and two cannabis cigarettes for 14 years, presented with a necrotic plaque of left hallux for 3 weeks. The Doppler ultrasound and angiography were compatible with severe Buerger's disease. Submitted to a revascularisation procedure and hypocoagulation with rivaroxaban. He had ceased smoking but maintained consumption of cannabis. Owing to the persistence of distal necrosis, amputation of the hallux was performed with good evolution...

More than 200 different surgical techniques exist for hallux valgus (HV). Some of them are designed for mild, moderate, or severe deformities depending on their correction power. Nevertheless, they all correct only the coronal and/or sagittal plane deformity. Just a handful of them correct the known axial malrotation that exists in most HV cases. This malrotation is one possible factor that could be the source of recurrence of an operated HV as it has been described. We describe a new technique which simultaneously corrects the metatarsal internal rotation and varus deformity by rotating the metatarsal through an oblique plane osteotomy...

The hallux valgus is a pathologic condition in the forefoot that often causes pain and functional limitations. Assessing all deformity components, such as the distal metatarsal articular angle (DMAA) is essential to hallux valgus treatment. Nevertheless, interobserver agreement of DMAA is poor on plain radiographs. The present study compared computed tomographic (CT) 3-dimensional (3D) reconstruction with plain radiographic measurements for measuring the DMAA. We included 43 consecutive patients (77 feet), diagnosed with hallux valgus at the orthopedic outpatient clinic at Hospital de Clínicas de Porto Alegre (Porto Alegre, Brazil) from April 2014 to June 2015 in our prospective study...

BACKGROUND: Taping is an effective temporary therapy for improving hallux valgus (HV) in adults. Although HV has been demonstrated to impair postural balance, there is a lack of information about how corrective taping affects balance and gait patterns in adults with HV deformity. METHODS: Eighteen middle-aged female patients (average age, 53.5 years) with HV were included. Corrective tape was applied to correct HV angulation. A series of balance and gait stability tests were performed before applying tape and 1 hour after the tape was applied with a Balance Master computerized posturography device...

INTRODUCTION: End stage hallux rigidus can be treated surgically by arthrodesis, excisional arthroplasty and implant arthroplasty. Evaluation of these techniques has focused on clinical indicators such as radiographic, complications and subjective examination. Little attention has been given to health related quality of life and the use of patient reported outcome measures is still infrequent. METHOD: An evaluation was undertaken in a community based podiatric surgery service...

We compared the outcomes of the distal oblique metatarsal (DOM) osteotomy, which is parallel to the articulation surface of the proximal phalanx, with those of the Chevron osteotomy and evaluated whether displacement and shortening of the first metatarsal have any effect on the incidence of metatarsalgia and patient satisfaction. Patients treated with the DOM osteotomy (n = 30) or distal Chevron osteotomy (n = 31) were evaluated retrospectively. The Chevron and DOM osteotomies both provided significant improvement in the first intermetatarsal angle (p < ...

Hallux valgus-the most common forefoot deformity-can cause both pain and decreased mobility. The development and progress of the hallux valgus is a multifactorial process. Different intrinsic and extrinsic causes are responsible. Various conservative and operative treatment options exist and have to been chosen regarding the stage of the disease. Conservative orthopedic measures may prevent a deterioration of hallux valgus only at an early stage of the disease. Concerning operative techniques, more than 150 different surgical procedures are described in the literature, which can be reduced to some common procedures...

The aim of this study was to design an algorithm to quantify the plantar force transference of children from ages 2-6. In total, 319 healthy children without abnormal gait patterns, foot deformities or injuries, able to walk independently, and with normal BMIs were recruited, and their plantar force distributions were measured. Their plantar areas were divided into ten parts: the hallux, toes #2-5, the first to fifth metatarsal heads (1st-5th MTH), the mid-foot (MF), medial heel (MH) and lateral heel (LH), in which a relative force-time integral (FTIrel) (%) was calculated...
