Janic Aebi, Monika Horisberger, Arno Frigg
BACKGROUND: Depending on the direction of the subtalar joint, a foot deformity generally tends towards pronation (pes planovalgus) or supination (pes cavovarus). However, the combination of hindfoot varus and flat midfoot/forefoot (pes planovarus) is an exception to this rule. Pes planovarus has so far only been referred to in connection with Müller-Weiss disease and congenital disease. We diagnosed pes planovarus in otherwise healthy patients without these diseases. METHODS: Forty patients with 54 symptomatic feet who were treated between August 2012 and July 2016 were included (mean age, 44...

OBJECTIVES: The literature lacks comparative data regarding foot segmental mobility in rearfoot (RFS) and midfoot striking (MFS) patterns. The aim of the study is to quantify the foot segmental mobility during distinct subphases of stance in presence of both striking patterns. METHODS: Twelve participants were instructed to run barefoot at a constant speed of 3.3m/s on a 10-m walkway, while adopting a RFS and a MFS pattern. Multi-segment foot mobility during the impact phase, the absorption phase and the generation phase was subsequently calculated and compared between both conditions...

OBJECTIVES: Advances in drug therapy for rheumatoid arthritis (RA) have been encouraging us to preserve the metatarsopharangeal (MTP) joint in correction of forefoot deformities, and original metatarsal shortening offset osteotomy was recommended as one of the conventional surgical options for forefoot deformities in RA cases. The objective of this study was to evaluate short- to mid-term outcomes of modified metatarsal shortening offset osteotomy. METHODS: A retrospective observational study was completed for 80 RA cases (mean follow-up period: 3...

BACKGROUND: Patellofemoral pain (PFP) is a prevalent, often recalcitrant and multifactorial knee pain condition. One method to optimize treatment outcome is to tailor treatments to the patient's presenting characteristics. Foot orthoses and hip exercises are two such treatments for PFP with proven efficacy yet target different ends of the lower limb with different proposed mechanisms of effect. These treatments have not been compared head-to-head, so there is a dearth of evidence for which to use clinically...

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...

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...

Tarsometatarsal (TMT) arthritis is characterized by instability and pain in the foot. The commonest cause is post-traumatic arthritis. A Lisfranc injury involves the articulation between the medial cuneiform and the base of the second metatarsal, which is considered a keystone to midfoot integrity. Neglected or undertreated injury to the Lisfranc joint complex leads to secondary arthritis and significant disability. We present a case of a young male patient with a two-year-old neglected Lisfranc joint injury and secondary osteoarthritis of the first, second, and fourth TMT joints, which we treated surgically with arthrodesis using screws, with a good functional outcome on final follow-up...

The Lisfranc fracture-dislocation of the foot is uncommon and diagnosis is often missed. The Lisfranc joint involves the articulation between medial cuneiform and base of the second metatarsal and is considered a keystone to structural integrity to the midfoot. The articulation has a stabilization effect on longitudinal and transverse arches of the foot. A neglected or untreated injury to the Lisfranc joint can lead to secondary arthritis and significant morbidity and disability. We present a case of a neglected Lisfranc fracture-dislocation in a 28-year-old female patient who presented 3 months after injury...

Foot and ankle fractures represent 12% of all pediatric fractures. Malleolar fractures are the most frequent injuries of the lower limbs. Hindfoot and midfoot fractures are rare, but inadequate treatment for these fractures may results in compartment syndrome, three-dimensional deformities, avascular necrosis and early post-traumatic arthritis, which have a significant impact on overall foot and ankle function. Therefore, the challenges in treating these injuries in children are to achieve adequate diagnosis and precise treatment, while avoiding complications...

Substantial progress has been made in the operative treatment of Lisfranc fractures, however, the prognosis remains poor. We hypothesized that Lisfranc injuries change the postural control and muscle strength of the lower limb. Both are suggested to correlate with the clinical outcome and quality of life. 17 consecutive patients suffering from a Lisfranc fracture dislocation were registered, underwent open reduction and internal fixation and were followed-up for 50.5±25.7months (Mean±SDM). Biomechanical analysis of muscle strength capacities, postural control and plantar pressure distribution was assessed >6 month postoperatively...

BACKGROUND: Plantar pressure leads to stress on plantar tissue and can be seen as risk factor for metatarsal stress fractures or plantar ulcers and is associated with prolonged and complicated recurrence of existing tissue damages. A clear demarcation of a systematic raise of body load regarding its effect on plantar pressure has not been described. OBJECTIVE: Assessing plantar pressure in different conditions of body weight, comparing data to initial body weight...

BACKGROUND: During pregnancy, physical and hormonal modifications occur. Morphologic alterations of the feet are found. These observations can induce alterations in plantar pressure. This study sought to investigate plantar pressures during gait in the last 4 months of pregnancy and in the postpartum period. A comparison with nulliparous women was conducted to investigate plantar pressure modifications during pregnancy. METHODS: Fifty-eight women in the last 4 months of pregnancy, nine postpartum women, and 23 healthy nonpregnant women (control group) performed gait trials on an electronic walkway at preferred speeds...

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...

It has been suggested that foot type consider not only foot structure (high, normal, low arch), but also function (over-pronation, normal, over-supination) and flexibility (reduced, normal, excessive). Therefore, this study used canonical regression analyses to assess which variables of foot structure, function, and flexibility can accurately discriminate between clinical foot type classifications. The feet of 61 asymptomatic, healthy adults (18-77 years) were classified as cavus (N=24), rectus (N=54), or planus (N=44) using standard clinical measures...

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: Patellofemoral pain (PFP) is a multifactorial and often persistent knee condition. One strategy to enhance patient outcomes is using clinically assessable patient characteristics to predict the outcome and match a specific treatment to an individual. AIM: A systematic review was conducted to determine which baseline patient characteristics were (1) associated with patient outcome (prognosis); or (2) modified patient outcome from a specific treatment (treatment effect modifiers)...

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...

OBJECTIVES: Lisfranc injuries are relatively uncommon midfoot injuries disproportionately affecting young, active males. Previous studies in civilian populations have reported relatively good results with operative treatment. However, treatment results have not been specifically examined in military personnel, who may have higher physical demands than the general population. The purpose of this study was to examine rates of return to military duty following surgical treatment of isolated Lisfranc injuries...
