Rigid flatfoot

OBJECTIVE: To examine the changes in the cross-sectional area (CSA) ratio of the ankle invertors and evertors following rigid foot orthosis (RFO) application in children with symptomatic flexible flatfoot and to determine the correlation between the degree of change in CSA ratio and pain-severity after RFO application. METHODS: We included 24 children with symptomatic flexible flatfoot without comorbidities and measured the CSAs of tibialis anterior (TA), tibialis posterior (TP), and peroneus longus (PL) using ultrasonography, resting calcaneal stance position (RCSP) angle, calcaneal pitch (CP), Meary's angle, talonavicular coverage angle, and talocalcaneal angle using radiography, and foot function index (FFI) at baseline and 12 months after RFO application...

INTRODUCTION: Bluman et al., flatfoot classification is based on posterior tibial tendon (PTT) dysfunction leading to a chronological appearance of several foot deformities. An expert consensus recently proposed a new classification named Progressive Collapsing Foot Deformity (PCFD) in which the focus was shifted to five different independent foot and ankle deformities and their flexibility or rigidity. The aim of this study was to compare Bluman and PCFD classifications. We hypothesize that both classifications will be reliable and that the PCFD classification will allow a larger distribution of the different types of foot deformity...

Tarsal coalition is determined by an absence of segmentation between one or more foot bones. The main symptom is activity-related foot pain, usually dorsolateral for calcaneonavicular coalitions and medial for talocalcaneal ones. At presentation, a symptomatic tarsal coalition must be treated conservatively for at least 6 months. If the conservative treatment fails and the foot is still painful, resection is the treatment of choice. Advantage of surgery is to restore mobility and reduce the risk of subsequent degenerative arthritis...

BACKGROUND: In progressive collapsing foot deformity (PCFD), hind- and midfoot deformities can be hard to characterize based on weightbearing plain radiography. Semiautomated 3-dimensional (3D) measurements derived from weightbearing computed tomography (WBCT) scans may provide a more accurate deformity assessment. In the present study, automated 3D measurements based on WBCT were used to compare hindfoot alignment of healthy individuals to patients with PCFD. METHODS: The WBCT scans of 20 patients treated at our institution with either a flexible (N = 10) or rigid (N = 10) PCFD were compared with the WBCT scans of a control group of 30 healthy individuals...

Arthrodesis of the hindfoot is typically used for the correction of severe and arthritic progressive collapsing foot deformity. Concomitant bony or soft tissue procedures may be helpful in patients with congenital abnormalities including the ball-and-socket ankle or congenital vertical talus. Dysplasia of the hindfoot bones may be more common than previously recognized, and corrective procedures or alterations in technique may need to be performed during hindfoot arthrodesis to account for bony deformity. Intraarticular osteotomies, extraarticular osteotomies, tendon lengthening, and tendon transfer procedures may be used in specific instances to aid in deformity correction and improve overall function...

BACKGROUND: Flexible flatfoot (FFF) is a very common condition in children, characterized by the loss of the medial arch and by an increase in the support base with valgus of the hindfoot. Arthroereisis (AR) procedures are widely performed corrective surgeries and are classified as subtalar AR and calcaneo-stop (CS). AIM: We investigated the literature published in the last 5 years with the aim of providing an update on the evidence related to AR treatment in FFF patients...

BACKGROUND: Foot orthoses are commonly used to correct for foot alterations and especially address excessive foot pronation in individuals with flatfeet. In recent years, 3D printing has taken a key place in orthotic manufacturing processes as it offers more options and can be patient specific. Hence, the purpose of this study was to evaluate whether stiffness of 3D printed foot orthoses and a newly designed rearfoot posting have an effect on lower limb kinematics and kinetics in individuals with flatfeet...

Flatfoot is commonly encountered in the paediatric population and describes a spectrum of clinical and radiological presentations which encompass both normally developing and pathological feet. Flatfoot can be categorised as flexible or rigid, a distinction which has important implications when considering the potential underlying aetiology and treatment options, and therefore imaging is an important component of the diagnostic workup. Weight-bearing plain radiographs are established initial investigations, although the significance of a number of the commonly derived quantitative parameters in children remains unclear...

Introduction: Tarsal coalitions in the general population are low, possibly due to the asymptomatic nature. In the symptomatic group, however, the presentation is usually during adolescence or early adulthood. The occurrence of a triple tarsal coalition is extremely rare, especially if not associated with a syndrome. Case Report: We report a case that has the unique configuration of talocalcaneal, talonavicular, and calcaneocuboid coalitions with a planovalgus foot...

AIMS: Passively correctible, adult-acquired flatfoot deformities (AAFD) are treated with joint-sparing procedures. Questions remain as to the efficacy of such procedures when clinical deformities are severe. In severe deformities, a primary fusion may lead to predictable outcomes, but risks nonunion. We evaluated pre- and postsurgical flexible AAFD patients undergoing joint-sparing or fusion procedures, comparing reoperation and complication rates. METHODS: We identified patients with flexible AAFD between January 1, 2001 and 2016...

Middle facet tarsal coalition is one of the commonly seen tarsal coalitions in clinical practice that can cause pain and associated flatfoot deformity. Excision of the coalition is one of the treatment options for symptomatic cases. Although symptoms may subside in children following a period of immobilization, resection should be considered as a treatment alternative for children and adolescents because of the potential for restoration of subtalar joint movement. The indications for excision of the coalition are not consistently reported in the literature, and the procedure is not always easy to perform...

BACKGROUND: The management of painful rigid flatfoot (RFF) with talocalcaneal coalition (TCC) is controversial. We aimed to compare operative and nonoperative treatment in children with RFF and TCC. METHODS: We retrospectively reviewed medical records and radiographs of children with RFF and TTC treated between 2005 and 2015. The nonoperative treatment consisted of manipulation under anesthesia, cast immobilization and shoe insert after cast removal. The operative treatment consisted of combined TCC resection, graft interposition and subtalar arthroereisis...

To analyze the efficacy of arthrodesis combined with osteotomy applied to subtalar, calcaneocuboid, and talonavicular joints for the treatment of adult rigid flatfoot.This retrospective study included 29 adult patients with rigid flatfoot who underwent triple arthrodesis combined with osteotomy from January 2015 to December 2017. All patients suffered from stage III of adult acquired flatfoot. Patients returned for a clinical and radiologic follow-up evaluation at an average of 19.5 (range, 15-27) months postoperatively...

Adult acquired flatfoot deformity (AAFD) is a common disorder that typically affects middle-aged and elderly women, resulting in foot pain, malalignment, and loss of function. The disorder is initiated most commonly by degeneration of the posterior tibialis tendon (PTT), which normally functions to maintain the talonavicular joint at the apex of the three arches of the foot. PTT degeneration encompasses tenosynovitis, tendinosis, tendon elongation, and tendon tearing. The malaligned foot is initially flexible but becomes rigid and constant as the disorder progresses...

Congenital vertical talus is an uncommon rigid flatfoot deformity present at birth, producing pain and disability if untreated. This study reports results and complications in a series of walking children affected by neglected congenital vertical talus treated by one-stage release through a double surgical approach in a hospital sited in the Tanzanian rural outback. Between 2009 and 2014, nine consecutive congenital vertical talus were observed in five patients (three males and two females) aged between 2 and 4 years...

BACKGROUND: Treatments of adult acquired flatfoot deformity in early stages (I-IIa-IIb) are focused on strengthening tendons, in isolation or combined with osteotomies, but in stage III, rigidity of foot deformity requires more restrictive procedures such as hindfoot joint arthrodesis. Few experimental studies have assessed the biomechanical effects of these treatments, because of the difficulty of measuring these parameters in cadavers. Our objective was to quantify the biomechanical stress caused by both isolated hindfoot arthrodesis and triple arthrodesis on the main tissues that support the plantar arch...

Müller-Weiss disease (MWD) is a dysplasia of the tarsal navicular. The shifting of the talar head laterally over the calcaneus drives the subtalar joint into varus. Failure to identify patients with paradoxic flatfoot varus may lead to the incorrect diagnosis and management. Conservative treatment with the use of rigid insoles with medial arch support and a lateral heel wedge is effective in most patients. Dwyer calcaneal osteotomy combined with lateral displacement seems to be a satisfactory treatment for patients who had failed to respond to conservative measures and a good alternative to the different types of perinavicular fusions...

CASE: Congenital vertical talus (CVT) is a rare rigid flatfoot disorder with a rocker-bottom flatfoot appearance. It is characterized by hindfoot valgus and equinus, with associated midfoot dorsiflexion and forefoot abduction. We describe a patient who was born with dysmorphic features and subsequently was diagnosed with Beals contractural arachnodactyly. After the diagnosis of bilateral CVT was made, it was treated with a single-stage open reduction. There was a unilateral recurrence, which was treated with revision surgery...

Rigid flatfoot deformity is a debilitating condition that can be managed by triple arthrodesis surgery. Triple arthrodesis has the potential to restore health-related quality of life, but it is also associated with several complications. Few studies have examined the 30-day readmission rates after triple arthrodesis. The objective of this study was to investigate risk factors for 30-day all-cause readmissions after triple arthrodesis. The nationwide readmission database was queried from 2013. By using International Classification of Disease, Ninth Revision, procedure codes, all triple arthrodesis procedures were identified...
