BACKGROUND: Arthrodesis of the first metatarsophalangeal (MTP1) joint is an intervention often used in patients with severe MTP1 joint osteoarthritis and relieves pain in approximately 80% of these patients. The kinematic effects and compensatory mechanism of the foot for restoring a more normal gait pattern after this intervention are unknown. The aim of this study was to clarify this compensatory mechanism, in which it was hypothesized that the hindfoot and forefoot would be responsible for compensation after an arthrodesis of the MTP1 joint...

BACKGROUND: Resection of the medial eminence in hallux valgus surgery is common. True hypertrophy of the medial eminence in hallux valgus is debated. No studies have compared metatarsal head width in patients with hallux valgus and control patients. METHODS: We reviewed 43 radiographs with hallux valgus and 27 without hallux valgus. We measured medial eminence width, first metatarsal head width, and first metatarsal shaft width in patients with and without radiographic hallux valgus...

BACKGROUND: This study was designed to measure transverse forces between the 1st and 2nd metatarsals after reducing the intermetatarsal angle (IMA) in normal and hallux valgus (HV) feet, during non weight-bearing and weight-bearing phases of gait. METHODS: Four cadaver feet, three normal and one with hallux valgus, were used. A new suture button device (CyclaPlex™) composed of screw-type buttons connected with a wire was implanted at the mid-shaft of the 1st and 2nd metatarsals of all the feet...

PURPOSE: Our aim was to identify the incidence and distribution of sesamoid bones plantar to the metatarsophalangeal (MTP) joints in adults, and to evaluate patterns of coincidence among these sesamoid bones. METHODS: We conducted a retrospective review of 7949 plain radiographs obtained from patients evaluated for foot trauma or symptomology. Associations between the distributions of MTP sesamoid bones as well as the association of age, sex, and laterality with identified prevalence, distribution, and coincidence were evaluated using Spearman's correlation coefficient...

BACKGROUND: In 1993, Chitayat et al., reported a newborn with hyperphalangism, facial anomalies, and bronchomalacia. We identified three additional families with similar findings. Features include bilateral accessory phalanx resulting in shortened index fingers; hallux valgus; distinctive face; respiratory compromise. OBJECTIVES: To identify the genetic aetiology of Chitayat syndrome and identify a unifying cause for this specific form of hyperphalangism. METHODS: Through ongoing collaboration, we had collected patients with strikingly-similar phenotype...

We compared the effect of two different positions of a sciatic nerve catheter within the popliteal fossa on local anaesthetic consumption and postoperative analgesia in patients undergoing day-case hallux valgus repair. Eighty-four patients were randomly allocated to receive a sciatic nerve catheter either between the tibial and peroneal components (sciatic group) or medial to the tibial nerve (tibial group). The primary endpoint was postoperative local anaesthetic consumption, while secondary endpoints were pain scores, number of occasions where sleep was disturbed by pain and incidence of insensate limb and foot drop at 24 h and 48 h postoperatively...

BACKGROUND: Multi-segment Foot Models (MFM) have increased in use for both clinical and research applications; however, little is known about the gender differences of inter-segmental motions within the foot and ankle during gait. The objectives of this study were to analyze the gender differences of inter-segmental foot motion during gait in healthy young adults using a MFM with a 15-marker set. METHODS: One hundred healthy adults (50 males, 50 females) between 20 and 35 years of age who had normal function and no radiographic abnormality, were evaluated...

A variety of surgical procedures exist for repair of both traumatic and degenerative osseous and soft-tissue pathologic conditions involving the foot and ankle. It is necessary for the radiologist to be familiar with these surgical procedures, so as to assess structural integrity, evaluate for complicating features, and avoid diagnostic pitfalls. Adequate interpretation of postoperative changes often requires access to surgical documentation to evaluate not only the surgery itself but the expected timeline for resolution of normal postoperative changes versus progressive disease...

BACKGROUND: Symptomatic Hallux valgus can be treated with metatarsal osteotomy combined with proximal phalangeal osteotomy, however this might not be sufficient to treat severe HV deformities. METHODS: Fifteen feet in eleven female patients treated with double first metatarsal and proximal phalanx osteotomies without lateral release were prospectively studied and outcome measures including radiological angles and validated patient reported outcome scores collected...

BACKGROUND: The medial sural artery perforator (MSAP) flap shows advantages for reconstruction in the foot and ankle, where bulk is a liability. We evaluated the versatility of this flap and provide further evidence on its use for covering small-to-moderate size defects by comparing the outcome depending on the region of reconstruction. METHODS: Twenty-two patients with variable defects of 4 × 4 to 18 × 7 cm underwent MSAP flap reconstruction. Final outcomes of all patients were evaluated 12-months postoperatively using the AOFAS ankle-hindfoot, midfoot and hallux scale for clinical-functional evaluation, and the SF-36 health survey for quality-of-life measurement...

: Hallux valgus is the most common disorder of the hallux and often results in pain, functional disability, and impaired gait patterns. The goals of surgical management are to correct the deformity while improving patients' pain and function. Traditional treatment of moderate to severe hallux valgus deformities consist of proximal osteotomy and/or arthrodesis given their powerful corrective ability. Despite their corrective power, proximal osteotomies are more technically demanding, have a higher rate of complications, and require a more restricted post-operative recovery...

BACKGROUND: Foot ailments are common among schoolchildren, some of which may be attributed to wearing ill-fitting footwear. As schoolchildren often participate in athletic activity, they are doubly vulnerable to foot ailments, and are particularly vulnerable to conditions such as hallux valgus, Achilles tendonitis, athlete's foot, corns and calluses. Thus, there is an acute need for the design and manufacture of ergonomic footwear for this target group. While research on appropriate footwear for children has been carried out in relation to child populations in other societies, research on the circumstances of Sri Lankan schoolchildren is lacking...

BACKGROUND: Operative correction of a symptomatic hallux valgus interphalangeus (HVI) deformity is often achieved with an osteotomy at the proximal end of the proximal phalanx (Akin osteotomy). However, the apex of the typical HVI deformity (center of rotation angle) is at the interphalangeal joint of the hallux. This study was done to evaluate the results of performing a medial closing wedge osteotomy at the distal end of the proximal phalanx. METHODS: Thirty-three patients (33 feet) underwent an osteotomy at the distal end of the proximal phalanx for correction of HVI...

BACKGROUND: Scarf osteotomy has been used in hallux valgus surgery due to its large fixation surface for screws and low postoperative complications. However, screws may cause skin irritation from their head, which may require an additional surgical procedure to remove. METHODS: This study included 115 patients (106 females and 9 males, 115 feet) who underwent hallux valgus correction with a scarf osteotomy using bioabsorbable screws between September 2010 and September 2012...

BACKGROUND: Corticosteroid injections have been used for a variety of foot and ankle pathologies over the years, and our aim was to evaluate the efficacy and safety of them in our clinic. MATERIALS AND METHODS: We performed a retrospective review of notes and a telephone questionnaire on the clinical outcome of all patients who underwent a corticosteroid injection of the foot or ankle in a year. All procedures were performed in an outpatient setting by a consultant musculoskeletal radiologist using either ultrasound or X-ray guidance and had a minimum of 2 years of follow-up...

BACKGROUND: Percutaneous surgery to correct deformities of the forefoot presents the advantages of using a minimal incision, which involves less soft tissue damage and less risk of wound complications. For severe deformities, percutaneous techniques have not been proven as effective. We propose a technique for the treatment of severe hallux valgus. METHODS: In a sample of 52 feet operated on 48 patients, we performed a double percutaneous osteotomy (closure proximal osteotomy and a distal Akin) or triple when a Reverdin-Isham osteotomy was added...

BACKGROUND: We aimed to compare the postoperative height of the second metatarsal head relative to the first metatarsal head using axial radiographs among 3 different commonly used osteotomy techniques: proximal chevron metatarsal osteotomy (PCMO), scarf osteotomy, and distal chevron metatarsal osteotomy (DCMO). METHODS: We retrospectively reviewed the radiographs and clinical findings of the patients with painful callosities under the second metatarsal head, complicated by hallux valgus, who underwent isolated PCMO, scarf osteotomy, or DCMO from February 2005 to January 2015...

In early theropod dinosaurs-the ancestors of birds-the hallux (digit 1) had an elevated position within the foot and had lost the proximal portion of its metatarsal. It no longer articulated with the ankle, but was attached at about mid-length of metatarsal 2 (mt2). In adult birds, the hallux is articulated closer to the distal end of mt2 at ground level with the other digits. However, on chick embryonic day 7, its position is as in early theropods at half-length of mt2. The adult distal location is acquired during embryonic days 8-10...
