#1
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...

BACKGROUND: Foot compartment syndrome (FCS) has been reported to cause neuropathic pain, claw or hammer toes, and motor and sensory disturbances. The optimal treatment of FCS is controversial. The purpose of this study was to determine if foot fasciotomies improve patient outcomes in high-energy, combat-related lower extremity trauma. METHODS: Medical records of patients with documented FCS from May 2007 to January 2009 were retrospectively reviewed. Consecutive, matched control patients were identified based on similar hindfoot, mid-foot and/or forefoot injuries who did not undergo foot fasciotomy during the same period...

BACKGROUND: Moderate to severe midfoot-forefoot varus deformities are commonly found in several conditions. However, few techniques are available to correct these deformities. So, we evaluated the clinical and radiological outcomes of patients who underwent midfoot derotational osteotomy to achieve plantigrade foot. METHODS: From 2006 to 2014, 6 patients (7 feet) underwent midfoot derotational osteotomy. A visual analog scale (VAS) pain and the American Orthopedic Foot & Ankle Society (AOFAS) functional score were evaluated...

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...

Objective: Foot and ankle exercise has been advocated as a preventative approach in reducing the risk of foot ulceration. However, knowledge about the appropriate types and intensity of exercise program for diabetic foot ulcer prevention is still limited. The current study aimed to examine the effects of an eight-week mini-trampoline exercise on improving foot mobility, plantar pressure and sensation of diabetic neuropathic feet. Methods: Twenty-one people with diabetic peripheral neuropathy who had impaired sensation perception were divided into two groups...

OBJECTIVES: Recent investigations have revealed lower vertical loading rates and knee energy absorption amongst experienced barefoot runners relative to those who rear-foot strike (RFS). Although this has led to an adoption of barefoot running amongst many recreational shoe runners, recent investigations indicate that the experienced barefoot pattern is not immediately realized. Therefore, the purpose this investigation was to quantify changes in lower-extremity dynamics and clinical outcomes measures for habitually shod runners who perform a transition to barefoot running...

Myoepitheliomas of soft tissue are rare tumors with variable morphologic, immunohistochemical and molecular profiles and therefore are diagnostically challenging for pathologists. We report a case in a 60-year-old male with a painless slowly growing 3cm mass on left medial forefoot. Core biopsy of the mass showed a neoplastic proliferation of plasmacytoid tumor cells, consistent with myoepithelioma of soft tissue. Immunohistochemical stains demonstrated positivity of the tumor cells for cytokeratin AE1/AE3, CK18, S-100 protein and myosin heavy chain (SMMS-1), supporting the diagnosis...

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...

Pedobarographic gait analysis is a useful tool for the determination of loading distributions and alterations on the lower extremity and their reflection on the foot sole after many orthopaedic surgical applications. To date, there have been no studies evaluating the relationship between component alignment and changes of pedobarographic gait analysis in total knee arthroplasty (TKA). We aimed to investigate the effects of TKA and prosthetic alignment on the distribution of pedobarographic parameters. Quantitative gait patterns of 47 patients were prospectively evaluated by using pedobarography 1 week before surgery and at the seventh month, on average, postoperatively...

A 50-year-old lady presented with a right foot mass and pain for 1year. Magnetic resonance imaging showed a 3.9×3.2×5cm mass on plantar side of the forefoot deep to the major flexor tendons and plantar aponeurosis and inferior to 1st-4th metatarsals. The mass extended dorsally through the intermetatarsal space to the foot dorsum. Ultrasound guided biopsy was performed, which confirmed it was a fibroma. This case was further complicated by pathological fracture of the 3rd metatarsal. It was resected through a dorsal incision and surgical dislocation of the 2nd and 3rd tarsometatarsal joints...

A 53-year-old woman presented with painful swelling of the right forefoot presenting clinically as a metatarsal stress fracture. Radiographs showed destructive changes, and diagnostic imaging revealed an aggressive neoplasm. The lesion was biopsied, and the pathologic diagnosis was metastatic melanoma. A thorough physical examination and advanced imaging did not reveal a primary tumor. Ray resection was performed with en bloc resection of the neoplasm. The patient continues to receive long-term immune stimulation chemotherapy 34 months after the ray resection...

Transmetatarsal amputation remains the standard treatment for the unsalvageable diabetic forefoot; however, this operation is often complicated by wound dehiscence, ulceration, and the need for additional surgery and tendon balancing. The technique described in the present report provides an uncomplicated suturing method for closure of a standard transmetatarsal amputation. A drill hole is created through the first, second, and fourth metatarsals, which facilitates added stability to the plantar flap of the residual metatarsals...

Anti-pronation orthoses, like medially posted insoles (MPI), have traditionally been used to treat various of lower limb problems. Yet, we know surprisingly little about their effects on overall foot motion and lower limb mechanics across walking and running, which represent highly different loading conditions. To address this issue, multi-segment foot and lower limb mechanics was examined among 11 overpronating men with normal (NORM) and MPI insoles during walking (self-selected speed 1.70±0.19m/s vs 1.72±0...

Indoor slippers with a strap across the dorsal forefoot are popular with older women. However, their influence on the foot motion has not been reported. This study evaluated the range of movement in the knee and ankle joints during walking and changes in trunk displacement during sit-to-stand when ten healthy older women worn two types of slippers and in their barefeet. Comparing to barefeet, walking in slippers results in significantly increases in the knee flexion angle in the swing phase. However, there is nonsignificant difference in the ankle angle in any phase across all conditions...

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...

AIMS: Morton's neuroma is common condition of the forefoot, but its aetiology remains unclear. Our aim was to evaluate the relationship between the width of the forefoot and the development of a Morton's neuroma. PATIENTS AND METHODS: Between January 2013 and May 2016, a total of 84 consecutive patients (17 men, 67 women) with a unilateral Morton's neuroma were enrolled into the study. The involved and uninvolved feet of each patient were compared. A control group of patients with symptoms from the foot, but without a neuroma who were matched for age, gender, affected side, and web space location, were enrolled...

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...

Ultrasound (US) imaging offers significant potential in diagnosis of plantar fascia (PF) injury and monitoring treatment. In particular US imaging has been shown to be reliable in foot and ankle assessment and offers a real-time effective imaging technique that is able to reliably confirm structural changes, such as thickening, and identify changes in the internal echo structure associated with diseased or damaged tissue. Despite the advantages of US imaging, images are difficult to interpret during medical assessment...
