PURPOSE: There is a paucity of evidence on the biomechanical effects of foot taping and foot orthoses in realistic conditions. This study aimed to determine the immediate effect and relationships between changes in multisegment foot biomechanics with foot taping and customized foot orthoses in adults with flat-arched feet. METHODS: Multisegment foot biomechanics were measured in 18 adults with flat-arched feet (age 25.1 ± 2.8 yr; height 1.73 ± .13 m, body mass 70...

BACKGROUND: Fusion of the first metatarsophalangeal joint (1st MTPJ) is a common surgical procedure used to treat a variety of diseases and deformities of the forefoot. Fixation methods vary and typically fusion rates are good. OBJECTIVES: The objectives of the study are to demonstrate whether there is any advantage to using locking as opposed to non-locking plates for 1st MTPJ fusion. Additionally the study aims to determine whether there is any difference in non-union rates according to gender...

OBJECTIVES: This study evaluates the influence of ligamentous laxity on the foot from observation of clinical signs and quantification of certain joint ranges. METHODS: The sample consisted of 400 subjects - 200 in the non-lax control group (ages 32.49 ± 11.06 years) and 200 in the lax group (ages 29.82 ± 9.41 years). The Beighton criteria were applied to each subject to diagnose laxity or non-laxity after noting their gender, age, and 2 joint ranges and 2 clinical signs for both feet...

BACKGROUND: Adequate sagittal plane motion of the first metatarsalphalangeal joint (1st MTPJ) is important during normal gait and goniometric measurement is commonly used as a diagnostic and outcome assessment tool. We aimed to determine the intra and inter-rater reliability together with the concurrent validity of a universal plastic goniometer (UG) and a smartphone applicationlication (Dr G) for the measurement of dorsiflexion at the 1st MTPJ. METHODS: Measurement of joint position and passive range of motion of the 1st MTPJ dorsiflexion was compared using a UG and DrG goniometer...

Acquired hallux varus secondary to traumatic disruption of the lateral joint structures of the 1st MTPJ is uncommon and has only been reported in the literature once previously.(4) We present a case of traumatic hallux varus that is unique since the deformity is dynamic in nature. In our patient the hallux remained reduced on standing weight bearing films, and luxated only during fluoroscopic stress testing. We also describe our surgical correction where a soft tissue anchor alone was utilized to stabilize the joint through repair of the lateral capsule and collateral ligament...

BACKGROUND: Persons with intellectual disabilities frequently have podiatric conditions. Limited information exists on their prevalence in international cohorts of Special Olympics (SO) athletes. Findings from multiple United States (US) venues are compared to those from athletes screened at the 2011 Special Olympics World Summer Games in Athens, Greece (ATHENS). METHODS: Data from Fit Feet screenings from 2096 ATHENS participants was compared to 7192 US participants...

Certain styles of children's shoes reduce 1st metatarsophalangeal joint (MTPJ) and midfoot motion during propulsion of walking. However, no studies have investigated if the splinting effect of shoes on children's 1st MTPJ and midfoot motion occurs during running. This study investigated the effect of sports shoes on multi-segment foot kinematics of children during propulsion of walking and running. Twenty children walked and ran at a self-selected velocity while barefoot and shod in a random order. Reflective markers were used to quantify sagittal plane motion of the 1st MTPJ and three-dimensional motion of the midfoot and ankle...

OBJECTIVES: To estimate the population prevalence of symptomatic radiographic osteoarthritis (OA) affecting the 1st metatarsophalangeal joint (MTPJ), 1st and 2nd cuneometatarsal joints (CMJs), navicular first cuneiform joint (NCJ) and talonavicular joint (TNJ) in community-dwelling older adults. METHODS: 9334 adults aged ≥50 years registered with four general practices were mailed a health survey. Responders reporting foot pain within the last 12 months were invited to undergo weight-bearing dorso-plantar and lateral radiographs of both feet...

BACKGROUND: The aim of this study is to investigate the amount of pressure reduction for different padding and insole materials commonly used in the podiatry clinic. METHODS: Plantar pressure were taken for 5 subjects without insoles fitted (BF) in their daily sports shoes, and thereafter with 4 pairs of simple insoles (6.4 mm thick) each as follow: SRP - Slow Recovery Poron, P - Poron, PPF - Poron+Plastazote (firm) and PPS - Poron+Plastazote (soft). In addition, subjects were also tested with semi-compressed felt (SCF) padding with a 1st metatarsophalangeal joint (MTPJ) aperture cut-out bilaterally...

BACKGROUND: Hallux rigidus (HR) is a common condition with history and physical examination used to help evaluate pathology, grade clinical changes and to inform treatment. METHOD: A cross-sectional study was undertaken to evaluate the demographics of and clinical parameters encountered in HR. In 110 subjects (180 feet) aged 18-70 years (mean 52 years) a standardized history and physical examination was undertaken. Clinical parameters associated with HR were evaluated...

BACKGROUND: Evidence regarding the efficacy of the MOJE ceramic press fit total joint replacement for the first metatarso-phalangeal joint (MTPJ) is lacking. OBJECTIVES: Our aim was to assess the clinical outcome for the MOJE arthroplasty in a single surgeon series using objective and subjective assessment tools. METHODS: A retrospective outcome study of 24 implants was performed in 22 patients undergoing first MTPJ replacement for osteoarthritis from 2004 to 2006...

The differential diagnosis for monoarticular arthritis is extensive. Patient omissions from the history can compound this broad diagnostic dilemma. A case report is presented of a 32-year-old female with an eight-month history of isolated right first metatarsophalangeal joint (MTPJ) pain, after exhaustive, non-specific diagnostic evaluation. An open biopsy was performed, and a 3.5 cm wooden foreign body, believed to be the result of an injury 18 years prior, was excised from the 1st MTP. Open biopsy may be required as an important part of the workup for definitive diagnosis of a foreign body synovitis...

The accessory extensor tendon of the first metatarsophalangeal joint (1st MTPJ) was evaluated in 32 cadaver feet. Eighty-one percent of feet possessed an accessory tendon to the 1st MTPJ. Of those feet possessing an accessory tendon to the 1st MTPJ, approximately 92% originated from the extensor hallucis longus muscle-tendon unit, while approximately 8% originated from the tibialis anterior muscle-tendon unit. All accessory tendons inserted onto the dorsal/dorsomedial capsule of the 1st MTPJ. Accessory tendons were found to be bilateral in the majority (87...

The 1 metatarsal double osteotomy is described as an effective procedure for the treatment of severe adolescent hallux valgus (AHV) with low recurrence and complication rates. No study to date has evaluated the functional clinical outcome after 1st metatarsal double osteotomy. The purpose of this paper is to report the results at our institution in the treatment of severe AHV with 1st metatarsal double osteotomy. We performed a review of all patients (N = 9, 14 feet) treated at our institution with 1st metatarsal double osteotomy...
