BACKGROUND: Forefoot structure is important to understand some foot problems such as hallux valgus and metatarsalgia. Ultrasonography (US) is a highly portable, noninvasive, low cost, and fast imaging method, especially when compared to magnetic resonance imaging (MRI), computed tomography (CT), and radiography. As the use of US for evaluating forefoot bony structure has not been validated, except for the presence of synovitis, erosions and bursitis within the forefoot in people with inflammatory arthritis, the purpose of this study was to determine whether US is a reliable method for evaluating forefoot structure...

BACKGROUND: A high proportion of flexor digitorum longus attachment is found at the posteromedial border of the tibia, which is the most common location of medial tibial stress syndrome (MTSS). Therefore, plantar flexion strength of the lesser toes could be related to MTSS; however, the relationship between MTSS and muscle strength of the hallux and lesser toes is not yet evaluated due to the lack of quantitative methods. This study investigated the muscle strength characteristics in runners with a history of MTSS by using a newly developed device to measure the muscle strength of the hallux, lesser toes, and ankle...

Distal osteotomies, like the Chevron osteotomy, is indicated for mild to moderate hallux valgus deformities. Splayfoot, painful pseudoexostosis, and transfer metatasalgia are observed in the clinical examination. Radiographic examination should be done with weight bearing in two planes. Preoperatively the intermetatarsal (IM), hallux valgus, and distal metatarsal articular (DMAA) angles should be measured. The operative technique is based on soft tissue and bony correction. Modifications of the osteotomy allow a shortening, lengthening, or neutral correction of the first metatarsal...

Hallux valgus is one of the most common deformities of the lower extremity. Multiple etiologies have been discussed, and various techniques have been described. The SCARF osteotomy is indicated for moderate to severe hallux valgus deformities. The technique historically used by carpenters allows immediate postoperative weight bearing and also entails the possibility to correct the distal metatarsal articular angle by rotation of the osteotomy. The SCARF osteotomy has also been successfully used in revision surgeries...

Sayed Ali, Nicole L Griffin, Whitney Ellis, Andrew J Meyr
It is important to have a full appreciation of lower-extremity anatomical relationships before undertaking diabetic foot surgery. We sought to evaluate the potential for communication of the flexor hallucis longus (FHL) tendon with other pedal tendons and plantar foot compartments at the master knot of Henry and to provide cadaveric images and computed tomographic (CT) scans of such communications. Computed tomography and subsequent anatomical dissection were performed on embalmed cadaveric limbs. Initially, 5 to 10 mL (1:4 dilution) of iohexol and normal saline was injected into the FHL sheath as it coursed between the two hallux sesamoids...

This prospective, observational study explored the need for pain-related unscheduled contact with healthcare services after outpatient surgery. We hypothesised that 10% of outpatients would have pain-related unscheduled contact with healthcare services, and that the incidence would differ depending on the type of surgical procedure. In total, 905 patients who had undergone one of five common outpatient surgical procedures (knee or shoulder arthroscopy, surgical correction of hallux valgus, laparoscopic cholecystectomy or laparoscopic gynaecological procedures) completed an electronic questionnaire one week and eight weeks after surgery...

BACKGROUND: Bipartite hallucal sesamoids are often found in patients with hallux valgus. However, it is unknown whether bipartite hallucal sesamoids affect the results of hallux valgus surgery or not. The purpose of the present study was to evaluate the outcomes of chevron osteotomy for hallux valgus with and without bipartite hallucal sesamoid. METHODS: A total of 152 patients (168 feet) treated with distal or proximal chevron osteotomy for hallux valgus constituted the study cohort...

Pes planovalgus (flatfoot) is a common deformity among children with cerebral palsy. The Milwaukee Foot Model (MFM), a multi-segmental kinematic foot model, which uses radiography to align the underlying bony anatomy with reflective surface markers, was used to evaluate 20 pediatric participants (30feet) with planovalgus secondary to cerebral palsy prior to surgery. Three-dimensional kinematics of the tibia, hindfoot, forefoot, and hallux segments are reported and compared to an age-matched control set of typically-developing children...

Toshinori Kurashige, Seiichi Suzuki
Coalition of the hallux sesamoids is an extremely rare condition. To our knowledge, only 1 case report has been published. We report a case of severe hallux valgus deformities with coalitions of the hallux sesamoids. The coalitions themselves were asymptomatic; however, this severe hallux valgus deformity needed to be surgically treated. The hallux sesamoids in both feet appeared to be fused and heart shaped on anteroposterior radiographs and dumbbell shaped on axial radiographs. It is known that postoperative incomplete reduction of the medial sesamoids can be a risk factor for the recurrence of hallux valgus...

M Thomas, M Jordan
Severe symptomatic hallux valgus deformities are usually not treatable with conservative methods in the long-term. Surgical treatment currently aims for mechanical restitution of the first ray with preserved mobility of the first metatarsophalangeal (MTP 1) joint and with low risk of recurrence after surgery. Keeping these aims in mind the surgical methods consist of osteotomy at the proximal part of the first metatarsal bone with a high potential for correction of the deformity. Surgical interventions at the midshaft level of the first metatarsal are only useful if the anatomical shape of the metatarsal shows a wide shaft, which allows a large shift in the osteotomy...

Oliver D Stone, Robbie Ray, Colin E Thomson, J N Alastair Gibson
BACKGROUND: The optimal operative management of hallux rigidus is still a matter for debate among surgeons. Despite arthrodesis widely considered to be the gold standard treatment, many surgeons advocate arthroplasty as a suitable alternative. There are, however, few long-term or high-quality studies evaluating these modalities. We present the 15-year follow-up of a randomized controlled trial. METHODS: This data is the follow-up to the original study published in 2005...

#12
Cameron Kia, Ryu Yoshida, Mark Cote, Jessica DiVenere, Lauren E Geaney
BACKGROUND: Proximal opening wedge osteotomy (POWO) is an established procedure for moderate to severe hallux valgus. A common concern of this procedure is that it results in lengthening of the first metatarsal, which could cause increased intra-articular pressure of the first metatarsophalangeal joint (MTP) and may ultimately lead to arthritis because of these altered mechanics. The purpose of this study was to use a cadaveric model to compare intra-articular pressures and articulating contact properties of the MTP joint following either scarf osteotomy or POWO...

R A Fuhrmann, W Rippel, A Traub
In hallux valgus syndrome conservative measures can only be applied to relieve the symptoms. Insoles, orthoses, and toe alignment splints cannot improve forefoot deformity. However, symptoms due to increased local pressure can be alleviated with orthotic devices. After surgically realigning the hallux, splints are helpful to retain joint congruency and assure proper toe position during soft tissue healing.

The tarso-metatarsal 1 joint (TMT-I) arthrodesis is a treatment option or moderate to severe hallux valgus (HV) deformities. Instability of the TMT1 joint is still a debatable indication. Using stable osteosynthesis techniques allows early postoperative weight bearing. Plantar plating combined with a lag screw is the biomechanical most stable construct. An additional intermetatarsal screw can improve the horizontal stability. Clinical results are good and radiological parameters stay constant, even in the long term...

Clinical and radiological examination of the foot are mandatory before surgical correction of the forefoot. The clinical examination includes leg axis, position of the hind foot, deformity of the first ray as well as skin conditions, pulse status and possible sensitive deficits. A shortening of the gastrocnemius muscle can be identified using the Silfverskiöld test. Discomfort in the midfoot can indicate pathologies of the tarsometatarsal joint and the same applies for osteophyte infiltration around the Lisfranc joint line, whereby the second tarsometatarsal joint often shows more advanced degenerative arthritis than the first tarsometatarsal joint...

Diabetes and its associated complications are realized as one of the most challenging medical conditions threatening more than 29 million people only in the USA. The forecasts suggest a suffering of more than half a billion worldwide by 2030. Amid all diabetic complications, diabetic foot ulcer (DFU) has attracted much scientific investigations to lead to a better management of this disease. In this paper, a system thinking methodology is adopted to investigate the dynamic nature of the ulceration. The causal loop diagram as a tool is utilized to illustrate the well-researched relations and interrelations between causes of the DFU...

The hallux valgus represents combined bony and soft tissue pathology. In addition to known bony surgical procedures, addressing the soft tissue with regard to the anatomical structures, the surgical technique and the extent of correction are discussed.The goal of the operation is the restoration of the physiological balance between the active and passive stabilizing factors of the MTP-I-joint. The joint capsule, the ligaments and the tendons of the first ray act directly as stabilizing structures, whereas the hind foot and the position of the upper ankle have an indirect influence on the MTP-I-joint...

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...
