BACKGROUND: It is usually accepted that acquired flatfoot deformity after injury is usually due to partial or complete tear of the posterior tibial tendon (PTT), with secondary failure of the other structures which maintain the medial longitudinal arch, such as the plantar calcaneo-navicular (SPRING) ligament. It is unusual to find an isolated Spring Ligament (SL) tear, with an intact TP tendon. METHODS: The medial arch reconstruction technique of an isolated SL tear in 5 patients is presented discussed in this paper...

BACKGROUND: Foot orthoses are frequently used in sports for the treatment of overuse complaints with sufficient evidence available for certain foot-related overuse pathologies like plantar fasciitis, rheumatoid arthritis and foot pain (e.g., metatarsalgia). One important aim is to reduce plantar pressure under prominent areas like metatarsal heads. For the forefoot region, mainly two common strategies exist: metatarsal pad (MP) and forefoot cushioning (FC). The aim of this study was to evaluate which of these orthosis concepts is superior in reducing plantar pressure in the forefoot during running...

OBJECTIVE: Medial longitudinal Arch Height is synonymous with classifying foot type and conversely foot function. Detailed knowledge of foot anthropometry is essential in the development of ergonomically sound footwear. Current Footwear design incorporates a direct proportionate scaling of instep dimensions with those of foot length. The objective of this paper is to investigate if a direct proportional relationship exists between human arch height parameters and foot length in subjects with normal foot posture...

In Charcot's osteoarthropathy stabilization of the medial column of the foot was introduced in order to establish a stable foot and reduce the risk for amputation. This study was performed to analyze postoperative complications, define risk factors for those and develop strategies for prevention. Since bolt dislocation takes place frequently, it was aimed to predict an appropriate time point for bolt removal under the condition that osseous healing has occurred. Fourteen consecutive patients with neuroosteoarthropathy of the foot and arch collapse were treated with open reduction and stabilization using midfoot fusion bolt and lateral lag screws...

BACKGROUND: Different characteristics of foot morphology are commonly accompanied by altering lower extremity biomechanical characteristics and foot function. Clarifying what factors affect foot morphology is helpful in understanding the basis of foot deformity and foot dysfunction. OBJECTIVE: The aim of this study was to investigate characteristics of foot morphology and whether related factors such as gender, age, body mass index (BMI) and bilateral asymmetry have an impact on foot morphology...

Pes planus is a condition that can cause pain along the innerfoot due to the absence or abnormal depression of the longitudinal arch. There are few studies available that compare therapy modalities used in these patients. In our study, those treated with conservative therapies - internal and external shoe modifications and pes planus exercises - were compared clinically and pedobarographyically. 60 pes planus patients were included in the study. In the first group; internal modification was performed by placing a medial longitudinal arch support inside the shoe...

Haglund's deformity was first described by Patrick Haglund in 1927. It is also known as retrocalcaneal exostosis, Mulholland deformity, and 'pump bump.' It is a very common clinical condition, but still poorly understood. Haglund's deformity is an abnormality of the bone and soft tissues in the foot. An enlargement of the bony section of the heel (where the Achilles tendon is inserted) triggers this condition. The soft tissue near the back of the heel can become irritated when the large, bony lump rubs against rigid shoes...

BACKGROUND: Debate exists regarding the effect of triple fusion on the development of osteoarthritis (OA) of the ankle joint. The midterm outcome after triple arthrodesis and the prevalence of OA following triple arthrodesis are reported in this study. The role of alignment in the development of OA was investigated. METHODS: Seventy five patients (87 feet) were evaluated in 2003 and of these, 48 patients (55 feet) were available for second evaluation in 2008. X-rays of the ankles and feet were made prior to surgery, in 2003 and in 2008, and the level of osteoarthritis (OA) was graded with the Kellgren and Lawrence score...

OBJECTIVE: To investigate foot biomechanics characteristic of patients with type 2 diabetes mellitus. METHODS: This study was conducted among 303 patients with type 2 diabetes. The whole foot was divided into 10 regions, namely the first toe (T1); the second to fifth toes (T2-5); the first, second, third, fourth, and fifth metatarsals (M1, M2, M3, M4, and M5, respectively); midfoot (MF), and the heel medial (HM). Foot arch index, foot angle and maximum peak pressure (MPP) of the 10 regions were measured using a Footscan gait system...

The spring (plantar calcaneonavicular) ligament complex connects the calcaneus and navicular bone of the foot and serves as the primary static stabilizer of the medial longitudinal arch of the foot. In this article, we describe the normal anatomy of the spring ligament complex, illustrate 3T magnetic resonance imaging appearances in its normal and abnormal states, and discuss the pathological associations with relevant case examples.

We compared patterns of intraepidermal nerve fibers and mechanoreceptors from affected and unaffected plantar skin from patients with pachyonychia congenita (PC) and control subjects. Plantar biopsies from 10 genetically confirmed patients with PC (with a mutation in KRT6A) were performed at the ball of the foot (affected skin) and the arch (unaffected) and were compared to biopsies from corresponding locations in 10 control subjects. Tissue was processed to visualize intraepidermal nerve fibers (IENF) (PGP9...

BACKGROUND: This study investigated the effect of Vibram FiveFingers Bikila minimalist shoes on intrinsic foot musculature. We hypothesized that a gradual transition into minimalist shoes will increase the thickness of the abductor hallucis muscle. METHODS: Forty-one individuals were divided into four groups: control (traditional shod) (n = 9), restricted walking in Vibram FiveFingers (n = 11), running in Vibram FiveFingers (n = 10), and unlimited walking in Vibram FiveFingers (n = 11)...

BACKGROUND: Over 1 in 3 older people with diabetes sustain a fall each year. Postural instability has been identified as independent risk factor for falls within people with Diabetic Peripheral Neuropathy (DPN). People with DPN, at increased risk of falls, are routinely required to wear offloading insoles, yet the impact of these insoles on postural stability and postural control is unknown. The aim of this study was to evaluate the effect of a standard offloading insole and its constituent parts on the balance in people with DPN...

: High- (HA) and low-arched athletes (LA) experience distinct injury patterns. These injuries are the result of the interaction of structure and biomechanics. A suggested mechanism of patellofemoral pain pertains to frontal plane knee moments which may be exaggerated in LA athletes. We hypothesize that LA athletes will exhibit greater peak knee abduction moments than high-arched athletes. METHODS: Twenty healthy female recreational athletes (10HA and 10LA) performed five over-ground barefoot walking and five barefoot running trials at a self-selected velocity while three-dimensional kinematics and ground reaction forces were recorded...

Previous studies have successfully used the longitudinal arch angle (LAA) to assess foot posture, but the measurement consistency and ability of the LAA to predict dynamic foot posture during activity in a variety of foot types have not been evaluated. The purpose of this study was to determine the reliability of the LAA as well as if the clinical method of assessing the LAA could be used to predict the LAA at midstance during walking for supinated, normal, and pronated foot types. The Arch Height Ratio was used to select 35 participants with 12 supinated, 46 normal, and 12 pronated feet...

The pronators and supinators play a key role in the medio-lateral stability of the ankle joint complex (i.e. talo-crural and subtalar joints). We hypothesized that each shank muscle has a specific activation pattern determined by its anatomical course around the axes of the subtalar and talo-crural joints. A secondary objective was to examine the effect of foot posture on these activation patterns. Forty-nine young adults (25 normal-arched feet, 24 flat-arched feet) performed maximum voluntary isometric contractions against manual resistance in four movement directions: plantarflexion (PF), dorsiflexion (DF), pronation (PRO) and supination (SUP)...

A 77-year-old male with subacute right foot ischemia was treated with endovascular therapy to relieve total thrombosis of the pedal arch extending from the dorsalis pedis of the anterior tibial artery into the posterior tibial artery, plantar segment. Because the procedure was only partially successful, rivaroxaban was used for thrombolytic treatment resulting in improvement of the patient's ischemic pain and avoidance of gangrenous progression and surgical amputation. This is the first report describing successful recanalization of pedal arch arterial thrombosis using rivaroxaban in a patient after suboptimal results of endovascular therapy...

CONTEXT: The intrinsic foot muscles maintain the medial longitudinal arch and aid in force distribution and postural control during gait. Impaired intrinsic foot-muscle function has been linked to various foot conditions. Several rehabilitative exercises have been proposed to improve it; however, literature that identifies which individual muscles are activated during specific intrinsic foot-muscle exercises is lacking. OBJECTIVE: To describe changes in activation of the intrinsic plantar foot muscles after 4 exercises as measured with T2 magnetic resonance imaging (MRI)...

Plantar load can be considered as a measure of the foot ability to transmit forces at the foot/ground, or foot/footwear interface during ambulatory activities via the lower limb kinematic chain. While morphological and functional measures have been shown to be correlated with plantar load, no exhaustive data are currently available on the possible relationships between range of motion of foot joints and plantar load regional parameters. Joints' kinematics from a validated multi-segmental foot model were recorded together with plantar pressure parameters in 21 normal-arched healthy subjects during three barefoot walking trials...

INTRODUCTION AND OBJECTIVES: Healthy feet are important for overall health and well-being. Previous studies of older subjects showed that those with a lowered arch had an increased odds of having foot deformities, pain, and hyperpronation in gait. (1-3) No investigation to date has comprehensively characterized foot biomechanics in a large sample of healthy active young subjects. METHODS: Foot structure, function, and arch height flexibility (AHF) were measured in 1,052 incoming cadets to the United States Military Academy...
