Zeynab Soltanzadeh, Saeed Shaikhzadeh Najar, M Haghpanahi, M R Mohajeri-Tehrani
A major purpose of investigating the plantar pressure in patients with pain or those at risk for skin injury is to reduce the pressure below metatarsal heads, specially first and second metatarsal heads. The aim of this article is to evaluate the effects of the socks structures on the changes in plantar dynamic pressure. In this study, seven socks types with different structures for the sole area were produced. The Gaitview(®) AFA-50 system, a force plate, was used to measure the plantar dynamic pressure of 10 participants...

Paolo Taboga, Alena M Grabowski
BACKGROUND: Prosthetic stiffness likely affects the walking biomechanics of toddlers and children with leg amputations, but the actual stiffness values for prostheses are not reported by manufacturers or in standardized testing procedures. AIM: We measured axial (kA) and torsional (kT) stiffness from four brands of pediatric prosthetic feet (Trulife, Kingsley Mfg. Co., TRS Incorporated, and College Park Industries) over a range of foot sizes. METHODS: We applied forces and torques onto prostheses with a materials testing machine that replicated those exhibited in vivo by using the kinetics measured from four non-amputee toddlers (2-3years) during walking...

BACKGROUND: Many factors are considered predictors of recurrence after hallux valgus (HV) surgery, including preoperative distal metatarsal articular angle (DMAA). The restoration of the bone and joint alignment would be more important than realigning the cartilaginous surface of the metatarsal head. Therefore, is DMAA correction essential for a good clinical and radiological results after HV surgery? This study aims to illustrate the results of percutaneous forefoot surgery (PFS) for correction of HV deformity without DMAA correction...

John J Fraser, Mark A Feger, Jay Hertel
Lateral ankle sprains (LAS) and chronic ankle instability (CAI) are common musculoskeletal injuries that are a result of inversion injury during sport. The midfoot and forefoot is frequently injured during a LAS, is often overlooked during clinical examination, and maybe contributory to the development of CAI. The purpose of part two of this clinical commentary and current concept review is to increase clinician's awareness of the contribution of midfoot and forefoot impairment to functional limitation and disability of individuals who experience LAS and CAI and to facilitate future research in this area...

OBJECTIVE: Cold allodynia occurs as a major symptom of neuropathic pain states. It remains poorly treated with current analgesics. Ciguatoxins (CTXs), ichthyosarcotoxins that cause ciguatera, produce a large peripheral sensitization to dynamic cold stimuli in Aδ-fibers by activating sodium channels without producing heat or mechanical allodynia. We used CTXs as surrogate model of cold allodynia to dissect the framework of cold allodynia activated central pain pathways. METHODS: Reversible cold allodynia was induced in healthy male volunteers by shallow intracutaneous injection of low nM concentrations of CTX into the dorsal skin of the forefoot...

INTRODUCTION: High energy injuries to the midfoot and forefoot are highly morbid injury groups that are relatively unstudied in the literature. Patients sustaining injuries of this region are challenging to counsel at the time of injury because so little is known about the short and long term results of these injuries. The purpose of this study was to investigate injury specific factors that were predictive of amputation in patients sustaining high energy midfoot and forefoot injuries...

Hao Wu, Jia-Gen Sheng, Chang-Qing Zhang
BACKGROUND: Although there are many surgical treatments for covering the skin defect of the fore-mid foot, how to reconstruct the weight-bearing region remains a challenge. The weight-bearing region of the sole needs to withstand the pressure and shearing stresses of walking, so the plantar skin is anatomically different from other skins in the areas of texture, thickness, subcutaneous tissue, etc. Medial plantar flaps that are harvested from the instep region are regarded as the first choice for weight-bearing region reconstruction because of their excellent functional and aesthetic long-term result...

BACKGROUND: Pedobarography offers dynamic information about the foot, but the interpretation of its large data is challenging. In a prior study it was shown that attention can be restricted to pedobarographic midfoot load data. We aim to verify this observation in ankle osteoarthritic and contralateral feet. METHODS: We assessed both feet of 120 patients with end-stage ankle osteoarthritis (OA) and 35 healthy volunteers with AOFAS-score and dynamic pedobarography in barefoot condition...

Clubfoot, known as congenital talipes equinovarus, is one of the complex paediatric foot deformity with the incidence of 1 in every 1000 live births. It consists of four complex foot abnormalities such as forefoot adductus, midfoot cavus, and hindfoot varus and ankle equinus. There are a number of surgical techniques (soft tissue releases, arthrodesis) used to correct clubfoot. However currently the conservative management (manipulation, serial casting, and braces) of clubfoot is considered as the best choice and it is widely accepted among orthopaedists...
