Pediatric Flatfoot Research Articles

AVALIAÇÃO DA TÉCNICA DE ARTRORRISE SUBTALAR NO TRATAMENTO DO PÉ PLANO VALGO FLEXÍVEL PEDIÁTRICO: UMA REVISÃO DE LITERATURA

Introduction: Flexible flatfoot is characterized by loss of the medial longitudinal arch and subtalar eversion and is a prevalent orthopedic condition among pediatric patients. Subtalar arthroereisis has emerged as an effective surgical option for the correction of this deformity, without the need for fusion of the subtalar joint or osteotomies. The aim of this study is analyze the available evidence on the efficacy and safety of subtalar arthroereisis in the treatment of flexible pediatric flatfoot. Methodology: This is an extended literature review study through bibliographic research using the terms subtalar, arthroereisis, and flexible flatfoot. The inclusion criteria included original articles published in the last 10 years. Results: Seven articles were selected to compose the review database. The studies addressed skeletally immature patients and evaluated the results of subtalar arthroereisis. Based on our articles, the results demonstrate a significant reduction in pain and adequate correction of deformities, regardless of the type of implant used – be it absorbable or non-absorbable. The procedure has a relatively low complication profile, which reinforces its reliability as a viable alternative for pediatric patients. The most common complications, such as implant loosening, incomplete correction, tarsal bone pain and screw breakage, were observed in a minority of cases. Conclusion: Subtalar arthroereisis presents an effective and safe surgical option for the treatment of flexible flatfoot foot in children.

Analysis of the Effect of Early Intensified Follow-Up on the Treatment of Pediatric Flatfoot With Subtalar Arthroereisis.

As children are a special group, the optimal management approach for pediatric patients with flatfoot after subtalar arthroereisis remains unclear. This study aims to explore the clinical effects of early intensified follow-up compared to conventional follow-up for such patients. We conducted a prospective study on 83 pediatric flatfoot patients from January 2019 to June 2022. Patients were divided into early intensive follow-up and routine follow-up groups. The study compared preoperative, 3 months postoperative, and 1-year postoperative Maryland Foot Function Scores, American Orthopedic Foot and Ankle Society (AOFAS) scores, and Visual Analogue Scale (VAS) scores, etc. At 3 months postoperatively, the early intensified follow-up group showed significantly higher Maryland Foot Score and surgery satisfaction compared to the conventional follow-up group. There were no statistical differences in other indicators at 3 months postoperatively, and all observed indicators at 1 year postoperatively. In conclusion, early intensive follow-up can accelerate the functional recovery process of pediatric flatfoot patients undergoing subtalar arthroereisis and improve surgical satisfaction. Increasing medical resource investment for enhanced postoperative management is valuable for such patients.

Postoperative Calcaneocuboid Joint Subluxation and Midtarsal Joint Changes in Pediatric Idiopathic Flexible Flatfoot Treated With Calcaneal Lengthening Osteotomy: A Midterm Follow-up Study.

Calcaneal lengthening osteotomy (CLO) is one of the main surgical options for treatment of pediatric idiopathic flexible flatfoot (FFF). Reportedly, calcaneocuboid (CC) joint subluxation occurs after CLO; however, its effect on the midfoot remains unclear. This study aimed to investigate the radiologic midterm results after CLO treatment in pediatric idiopathic FFF. We evaluated 23 pediatric patients with idiopathic FFF aged ≥8 years, who underwent CLO from 1999 to 2017 owing to moderate to severe flatfoot deformity (assessed by visual inspection). Patients aged between 8 and 14 years were included (mean follow-up: 6.3 years; range, 3.1-11.4 years). Anteroposterior and lateral weightbearing foot radiographs were assessed for radiologic parameters preoperatively and at the 3-month, 1-year, and final follow-ups postoperatively. All patients had immediate postoperative radiologic correction of the flatfoot deformity, and these improvements were maintained until the final follow-up. The mean allograft length inserted was 9 (range, 8-10) mm. There was increased CC joint subluxation after CLO, but it improved continuously until the final follow-up. A CC joint spur was newly noted in 1 case. There were 24 cases (24/39, 61.5%) of talonavicular (TN) joint spurs at the final follow-up, but 19 of these were already present on the preoperative radiographs (19/24, 79.2%). Further, the new-onset TN joint spurs were not associated with preoperative clinicoradiologic factors. In pediatric patients with idiopathic FFF receiving CLO treatment, preoperative radiologic angles improved. CC joint subluxation increased after surgery; however, it gradually reduced without evidence of CC joint arthritic changes over the time period studied in this cohort.

Do First Ray-Related Angles Change following Subtalar Arthroereisis in Pediatric Patients? A Radiographic Study.

Subtalar Arthroereisis (STA) is a surgical intervention for pediatric flexible flatfoot (PFF), primarily targeting hindfoot alignment by limiting excessive subtalar eversion. However, its effects on forefoot parameters remain underexplored. This study aims to investigate radiological changes following STA in pediatric patients. A retrospective analysis was conducted on consecutive patients treated with STA for PFF. First ray-related angles, including the Hallux Valgus Angle (HVA) and the Intermetatarsal Angle (IMA), alongside hindfoot radiological parameters such as the Meary, Calcaneal Pitch, and Costa Bartani angles, were assessed. Subgroup analysis by gender was performed, and correlations between demographic and preoperative radiological parameters were examined. Forty-one patients (81 feet) with an average age of 11.6 years were included, with a mean follow-up duration of 6.4 months. No significant differences were observed in first ray-related angles pre-and postoperatively, with the mean IMA changing from 7.97° to 7.18° and the mean HV angles changing from 9.51° to 8.66°. Noteworthy improvements were seen in flat foot angles, including the Meary, Calcaneal Pitch, and Costa Bartani angles, postoperatively. The age subgroup analysis revealed similar trends in IMA and HVA changes between Group A (who underwent surgery before peak growth) and Group B (who underwent surgery after peak growth). Higher preoperative angles tended to improve, while lower preoperative IMAs and HVAs tended to worsen postoperatively, all remaining within normal ranges. STA showed positive radiological outcomes for PFF treatment, while negligible changes in first ray-related angles were observed. The age subgroup analysis indicated similar trends regardless of operation timing. Higher preoperative angles tended to improve, while lower preoperative angles tended to worsen postoperatively, despite all falling within non-pathological ranges. Further research is warranted to confirm this correlation.

High Rate of Change of the Foot in Ecuadorian Children: The Need for Proper Shoe Design.

Physiological changes in the foot may be influenced by external factors such as shoe types or demographic parameters, leading to podiatric conditions in adulthood. The aim of this study was to assess the changes in morphological measurements of the feet of boys and girls during childhood and adolescence. A total of 1678 Ecuadorian children aged 8 to 17 years participated in the study. The length, width, and height of the foot were analyzed using a 3D scanner to obtain the arch height ratio for the diagnosis of pediatric flat foot. Statistical differences were observed for lengths, widths, and perimeters of the foot in boys aged 5 to 15-16 years and girls aged 5 to 12-13 years. Differences in the height of the navicular bone were found in all age groups, with changes from 2.8 to 4.1% in boys and from 1.3 to 1.5% in girls. The greatest differences between boys and girls of the same age were found at 14 years old onwards. The highest prevalence of flat foot was found in 8-year-old girls (64.9%) and in 12-year-old boys (82.5%). The feet of Ecuadorian children develop progressively during childhood and adolescence. Boys presented with longer and wider feet than girls of the same age. The highest prevalence of flat foot was found in 12-year-old boys and 8-year-old girls.

Dynamic Gait Analysis in Paediatric Flatfeet: Unveiling Biomechanical Insights for Diagnosis and Treatment.

Flatfeet in children are common, causing concern for parents due to potential symptoms. Technological advances, like 3D foot kinematic analysis, have revolutionized assessment. This review examined 3D assessments in paediatric idiopathic flexible flat feet (FFF). Searches focused on paediatric idiopathic FFF in PubMed, Web of Science, and SCOPUS. Inclusion criteria required 3D kinematic and/or kinetic analysis during posture or locomotion, excluding non-idiopathic cases, adult feet, and studies solely on pedobarography or radiographs. Twenty-four studies met the criteria. Kinematic and kinetic differences between FFF and typical feet during gait were outlined, with frontal plane deviations like hindfoot eversion and forefoot supination, alongside decreased second peak vertical GRF. Dynamic foot classification surpassed static assessments, revealing varied movement patterns within FFF. Associations between gait characteristics and clinical measures like pain symptoms and quality of life were explored. Interventions varied, with orthoses reducing ankle eversion and knee and hip abductor moments during gait, while arthroereisis normalized calcaneal alignment and hindfoot eversion. This review synthesises research on 3D kinematics and kinetics in paediatric idiopathic FFF, offering insights for intervention strategies and further research.

Distribution of plantar pressures under static conditions, in various areas of the pediatric flatfoot in sensitive period of development – pilot study

Background: Flatfoot can alter the foot's ability to uniformly distribute the body weight on the plantar areas, possibly leading to biomechanical imbalances in the entire body. The purpose of the study was to determine the correlation between flatfoot and plantar pressure distribution in static conditions. (2) Material and methods: The study included a group of 23 children with flat feet (7.43±0.58 years old), which analyzed the correlations between the Foot Posture Index 6 (FPI 6) values and the plantar pressure distribution values. The instruments used were the Foot Posture Index 6 (FPI 6- a quantitative anatomical assessment under static conditions) and the Podata (device for recording images in real time of the body weight distribution on the plantar support). (3) Results: The statistical results have indicated significant correlations of strong intensity between the flat foot and the plantar pressure distribution in the midfoot, but also that the flatfoot significantly influences the values of the plantar pressure distribution in the midfoot. (4) Conclusion: The data showed that flatfeet influence the values of the plantar pressure distribution in the mid-area of the sole.

Comparation of outcomes of iliac crest bone graft and accessory navicular bone graft in the Cotton osteotomy for pediatric and adolescent flexible flatfoot

Objective: To compare the outcomes between iliac crest and accessory navicular as different bone grafts in the Cotton osteotomy in the treatment of pediatric flexible flatfoot deformity. Methods: A retrospective cohort study. The clinical data of pediatric flexible flatfoot patients with symptomatic accessory navicular received operations from July 2018 to March 2022 in Beijing Tongren Hospital were retrospectively analyzed. All the patients were treated with Cotton osteotomy. According to the different sources of bone grafting in Cotton osteotomy, the patients were divided into iliac crest group and accessory navicular group. There were 12 patients (19 feet) in iliac crest group, including 9 males and 3 females with a median age M(Q1, Q3) of 11(11, 12) years and were followed-up for 36(6, 48) months. There were 9 patients (16 feet) in accessory navicular group, including 6 males and 3 females, with a median age M(Q1, Q3) of 11(11, 11) years and were followed-up for 12(6, 17) months. Radiographic evaluations were reviewed and compared between the two groups before surgical treatment and at final follow-up, included talo-1st metatarsal angle (T1MT), talonavicular coverage angle (TNCA), talocalcaneal angle (TCA) in weight bearing anteroposterior view, and Meary angle, calcaneal Pitch angle, Kite angle, cuneiform articular angle (CAA) in weight bearing lateral view, and hindfoot alignment angle (HAA) in calcaneal long axial view. Functional scores included American Orthopedic Foot and Ankle Society (AOFAS), visual analog scale (VAS), and Maryland scores were recorded and compared before and after the operation. The complications were also recorded. Results: Total of 21 patients were successfully followed in this study. The radiographic measurements in the two groups, such as T1MT, TNCA, Meary angle, Pitch angle, Kite angle, CAA, HAA, were all significantly improved at the last follow-up when compared with those before the surgery (all P<0.05); and the AOFAS, VAS, Maryland scores in both groups were all improved after the surgery (all P<0.05). There was a significant difference in CAA alteration (∆CAA) after the operation between the two groups, the ∆CAA in iliac crest group and the accessory navicular group was 6.0°±2.6° and 4.3°±1.3°, respectively (P=0.017). There was no significant differences in the improvement of other radiographic measurements between the two groups (all P>0.05). All the patients had a successful bone union. Two patients had donor site pain in the iliac crest group and were treated conservatively. Conclusion: Compared with iliac crest bone graft, accessory navicular bone graft could achieve comparable outcomes in radiographic measurements and functional scores in the treatment of pediatric flexible flatfoot with accessory navicular pain.

Mid-term assessment of subtalar arthroereisis with Talar-Fit implant in pediatric patients with flexible flatfoot and comparing the difference between different sizes and exploring the position of the inserted implant.

Subtalar arthroereisis (STA) has gained growing acceptance as a viable approach solution for the management of pediatric flexible flatfoot. However, STA still remains controversial. The purpose of this study is to assess the effect of STA using the Talar-Fit implant for treating pediatric flexible flatfoot. Specifically, the aims of the study are as follows: first, to present the mid-term outcomes of STA using the Talar-Fit implant; second, to compare the radiographic and clinical outcomes associated with varying sizes of Talar-Fit implant; and third, to analyze the optimal position of the inserted implants. A retrospective analysis was conducted on a cohort of 57 pediatric patients diagnosed with flexible flatfoot (77 feet) who underwent STA utilizing Talar-Fit between January 2014 and December 2021. The participants were categorized into five groups according to the size of the implant: Group 8, Group 9, Group 10, Group 11, and Group 12. The evaluation included the assessment of clinical function using the American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hind foot score, as well as the assessment of radiographic data such as the calcaneal pitch angle (CPA), lateral Meary angle (LMA), talar declination angle (TDA), and medial longitudinal arch angle (MLAA) were evaluated. Furthermore, the position of the inserted implants was also recorded, including angle, depth, and distance. The comparison of pre- and postoperation was conducted using the paired Student's t-test, whereas the analysis of differences among subgroups was performed using the Wilcoxon rank-sum test. A P-value < 0.05 is considered statistically significant. In total, 57 pediatric patients (77 feet) were successfully followed-up for an average period of 26.8 months. The overall AOFAS score significantly improved from 58.6 ± 10.9 to 85.2 ± 8.6 (P < 0.001). Furthermore, the LMA decreased from 20.3° ± 3.6° to 4.5° ± 1.3°, the CPA increased from 14.8° ± 1.6° to 23.6° ± 2.7°(P < 0.05), the TDA decreased from 40.2° ± 2.3° to 25.5° ± 3.2°(P < 0.05), and the MLAA decreased from 140.1° ± 2.8° to 121.4° ± 3.9°(P < 0.05). No statistically significant differences were observed among subgroups regarding the final outcomes. The improvements of CPA, TDA, and MLAA among different groups were significantly different; however, the adjusted P-values were all greater than 0.05. The implant were inserted at a mean angle of 89.5° ± 2.4°, a mean depth of 0.9 mm ± 2.1 mm, and a mean distance of 9.9 mm ± 0.9 mm. Eight patients experienced complications, including six cases of pain occurrence and two cases of implant dislocation. STA with Talar-Fit has demonstrated satisfactory mid-term outcomes. A Talar-Fit with a larger size may demonstrate a superior effect when compared with that of a smaller size. The implants were inserted in a similar position, indicating that the medial edge of the implant may be possible to transcend the midline of the talus neck.

Nonunion Rate of Evans Osteotomy Without Fixation Pediatric Flatfoot

Category: Hindfoot; Other Introduction/Purpose: The Evans osteotomy is a calcaneal lateral column lengthening procedure commonly used to correct flatfoot deformities. Currently, there is no consensus on whether fixation is needed when performing this osteotomy. Also, large sized grafts have been found to lead to degeneration of the calcaneocuboid joint. The aim of this study was to determine the nonunion rate of an unfixed Evans osteotomy with use of an allograft wedge performed in patients undergoing flexible flatfoot reconstruction and if addition of a medial calcaneal slide osteotomy will help limit graft size. Methods: We retrospectively reviewed 39 pediatric patients with idiopathic symptomatic flatfoot deformity who underwent 46 unfixed Evans osteotomies with allogenic bone graft for flatfoot reconstruction between March 2013 and September 2017, with a mean follow-up of 49 (range 9.9- 243.9) weeks. Hospital record, preoperative, follow-up radiographs and complications were reviewed. Results: Of the 46 feet, 42(91.3%) underwent an associated medial displacement calcaneal osteotomy. Mean graft wedge size was 7.2mm(SD 1.6). Mean time to union was 10.3weeks (range, 6.7-13.9)(Table 1). There were no nonunions. There was significant improvement in all radiographic parameters at final follow-up (Table 2). Postoperative calcaneocuboid subluxation occurred in 70% of feet, with no correlation with wedge size(r=0.01,p=0.53). Magnitude of calcaneocuboid subluxation was small and only significant at 6-months (p=0.02), with regression to no significance by 1-year(p=0.3). Mean change in calcaneocuboid subluxation at final follow-up was 1.07mm(SD 2.18), with postoperative subluxation diminishing over time(Table 3). No correlation was observed between wedge size and change in lateral column length (r=0.01,p=0.45). One patient had persistent sinus tarsi pain requiring arthroscopic debridement of fibrosis and graft prominence. Conclusion: An unfixed Evans osteotomy for symptomatic pediatric flatfoot deformity resulted in a significant improvement in the radiographic alignment and achieved 100% union rate with minimal calcaneocuboid subluxation at final follow-up. Performing adjunctive procedures allowed the Evans procedure to be routinely limited to less than 10 mm of lengthening. Mean graft size in our cohort was smaller than that reported by other studies. While calcaneocuboid subluxation was detectable in 70% of feet, it was small in magnitude and diminished with longer postoperative follow-up.

Is There a Benefit to Rigid Fixation in Calcaneal Lengthening Osteotomy in Painful Pediatric Idiopathic Flatfoot Deformity? Comparing Results of Kirschner Wire Versus Plate Fixation.

Flexible flatfoot (FF) is a common pediatric condition that is mostly asymptomatic, and surgical intervention is only considered when painful FF is refractory to conservative treatment. Calcaneal lengthening osteotomy (CLO) is one of the most commonly used procedures to address painful FF. Traditionally, Kirschner wires (K-wires) were used for fixation, but there has been a recent increase in the use of plates. We compared the clinical and radiographic outcomes of these 2 fixation methods. This single-center retrospective study included children aged 8 to 18 years with symptomatic FF that received CLO using K-wire or plate fixation. Primary outcomes include weight-bearing radiographic measurements and complications after surgery. Secondary outcomes included patient-reported outcomes. Statistical significance was held at 0.05. Among 102 feet (65 patients), 42 feet (41.2%) underwent K-wire and 60 feet (58.8%) underwent plate fixation. No differences in casting duration ( P =0.525) and time-to-radiographic healing ( P =0.17) were noted. Total complications were higher in the plate cohort (12 vs. 2, P =0.04) due to a higher rate of reoperations (16.7%) for hardware-related pain [10 vs. 0; odds ratio 17.74, 95% CI (1.01, 310.54), P <0.05], and infection rates were similar. Both interventions significantly improved ( P ≤ 0.001) aneteroposterior (AP) Talo-first metatarsal and calcaneal pitch angles. Irrespective of intervention, CLO significantly improved pain at 6 months and mobility scores at 12 months. Neither modality demonstrated superior pain or mobility scores at final follow-up. Both K-wire and plate fixations lead to similar radiographic and functional outcomes after CLO in painful, pediatric flatfeet. Compared with K-wire fixation, plates cause a 17.7-fold increased risk of reoperations for painful hardware, with 16.7% of plated cases requiring reoperation. Noting this, along with the higher costs associated with using plates, our study advocates for K-wire fixation for children undergoing CLO. Level III.

Efficacy of Personalized Foot Orthoses in Children with Flexible Flat Foot: Protocol for a Randomized Controlled Trial.

Pediatric flat foot (PFF) is a very frequent entity and a common concern for parents and health professionals. There is no established definition, diagnostic method, or clear treatment approach. There are multiple conservative and surgical treatments, the implantation of foot orthoses (FO) being the most used treatment. The evidence supporting FO is very thin. It is not clearly known what the effect of these is, nor when it is convenient to recommend them. The main objective of this protocol is to design a randomized controlled trial to determine if personalized FO, together with a specific exercise regimen, produce the same or better results regarding the signs and symptoms of PFF, compared to only specific exercises. In order to respond to the stated objectives, we have proposed a randomized controlled clinical trial, in which we intend to evaluate the efficacy of FO together with strengthening exercises, compared to a control group in which placebos will be implanted as FO treatment along with the same exercises as the experimental group. For this, four measurements will be taken throughout 18 months (pre-treatment, two during treatment and finally another post-treatment measurement). The combination of FO plus exercise is expected to improve the signs and symptoms (if present) of PFF compared to exercise alone and the placebo FO group. In addition, it is expected that in both conditions the biomechanics of the foot will improve compared to the initial measurements.

Pediatric Flatfoot: Is There a Need for Surgical Referral?

Pediatric foot deformities are a common finding, concerning up to 44% of preschool aged children. The absence of accepted international guidelines, as well as heterogeneity in definitions and measurements, makes management of pediatric flatfoot a challenge, and decisions surrounding specialized care referral confusing and biased. The objective of this narrative review is to provide guidance to primary care physicians treating these patients. A non-systematic review of the literature regarding the development, etiology, and clinical and radiographic assessment of flatfeet using the PubMed and Cochrane Library databases was performed. The exclusion criteria for the review were adult populations, papers detailing the outcome of a specific surgical procedure, and publications prior to 2001. The included articles showed great heterogeneity in definition and proposed management, which makes the study of pediatric flatfoot challenging. Flatfoot is a common finding in children under 10 years old, and should not be considered pathological unless stiffness or functional limitation are present. Surgical referral should be reserved to children with stiff or painful flatfoot, while simple observation is indicated for flexible, asymptomatic flatfeet.

Is Kidner procedure necessary during subtalar arthroereisis for pediatric flexible flatfoot that combined with symptomatic type 2 accessory navicular? A retrospective comparative study

BackgroundKidner procedure is thought to be able to eliminate the medial foot pain and contribute to restoring the medial longitudinal foot arch, making it particularly suitable for surgical treatment of pes planus that combined with symptomatic type 2 accessory navicular (AN). However, controversy remains, and the clinical evidence is still lacking. The aim of the current study is to verify the necessity of Kidner procedure during subtalar arthroereisis (STA) for pediatric flexible flatfoot (PFF) that combined with symptomatic type 2 AN. MethodsForty pediatric patients (72 feet) who had undergone STA for flexible flatfoot and were also diagnosed with symptomatic type 2 AN concomitantly were reviewed retrospectively and divided into two groups (STA + Kidner vs STA alone). The visual analog scale (VAS), the American Orthopaedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot Scale, the Oxford ankle foot questionnaire for children (OAFQC), and the radiographic parameters that quantifying pes planus were evaluated as primary outcomes. Secondary outcomes included the incidence of complications. ResultsThere were 35 feet in the STA + Kidner group and 37 feet in the STA alone group, with mean follow-up periods of 2.7 years and 2.1 years, respectively. The VAS, AOFAS, OAFQC scores and radiographic parameters presented no significant difference between the two groups both preoperatively and at final follow-up (P > 0.05 for each). The complications of STA surgery occurred equally in both groups, and Kidner procedure could lead to more incision problems (22.9% vs. 2.7%) and a longer time to return to activity. ConclusionKidner procedure may be unnecessary during surgical treatment of PFF that combined with painful type 2 AN. Correcting the PFF while leaving the AN alone has a high possibility of relieving the pain in the AN region, and tibialis posterior tendon (TPT) rerouting hardly aids in reconstruction of the medial foot arch. Level of EvidenceIII.

Pediatric and Adolescent Flatfoot: A Questionnaire Based Middle East and North Africa Study.

Flatfoot is commonly seen in the community and is a common cause of concern for parents because it could become symptomatic and lead to decreased quality of life. One of the most used management approaches is foot orthoses, although no clear evidence supports their use. We aimed to study flatfoot symptoms' prevalence, effect on activities of daily living, and the use and effectiveness of orthoses. This was a cross-sectional study that included five countries from the Middle East and North Africa region (Jordan, Palestine, Syria, Egypt, and Iraq). Data were collected using an online questionnaire directed toward parents of children aged 0 to 16 from September to December 2020. The demographic factors were expressed as frequencies (percentages) using standard descriptive statistical parameters, and Pearson's chi-square test was used to examine the relationship between study factors. 1256 participants were recruited using this online survey. The majority (29.6%) of children were diagnosed in the age group of 0 to 2. The abnormal appearance of the foot was the most common (78.7%) complaint. Overall, 54.2% of patients were prescribed orthoses, of which 36.8% noticed improvement in flatness and 37.6% reported relief of symptoms. This study demonstrated that most participants have no or minimal symptoms and that there is a mismatch between participants' expectations and the actual effectiveness of orthoses. Taking into consideration that there is no clear evidence to support the corrective effect of orthoses, we recommend that physicians prescribing them adhere more to their proper indications and spend more time and effort counseling and addressing patients' and parents' concerns about this developmental stage.

Comparativestudy between the calcaneo stop procedure and endorthesis in the management of pediatric symptomatic flexible flatfoot

Purpose The aim of the study was to compare the results of using the calcaneo stop procedure and endorthesis in the management of symptomatic flexible flatfoot (FFF) in pediatrics. Patients and methods This is a prospective randomized study using the closed envelope technique. It was conducted on 30 feet of 19 patients admitted in the National Institute of Neuromotor System. All cases presented with symptomatic flexible pes planovalgus. The current study started in May 2020 and ended in January 2022. Written detailed informed consents were obtained from parents. Inclusion criteria were age 7–14 years, symptomatic idiopathic FFF, failed conservative treatment, and no previous foot surgery. Exclusion criteria were children young than 7 years or older than 14 years, rigid flatfeet, asymptomatic FFF, patients with major congenital malformations, severe neurological disorders, patients with neuromuscular disorders, patients subjected to other foot surgery, and patients with traumatic flatfeet. The patients were randomly assigned into two groups: group 1 included 15 feet of nine patients (six bilateral and three unilateral) who underwent the calcaneo stop technique, and group 2 included 15 feet of 10 patients (five bilateral and five unilateral) who underwent endorthesis by subtalar fit implant. The mean age of group 1 was 9.90 ± 2.86 years (range, 7–14 years), whereas of group 2 was 9.70 ± 1.50 years (range, 8–14 years). There were 10 male patients (five underwent calcaneo stop and five endorthesis) and nine female patients (five underwent calcaneo stop and four endorthesis). The right foot was operated upon in 16 cases, and the left foot was operated upon in 14 cases. The average AOFAS preoperative score in group 1 was 68.7 ± 5.7 (range, 58–78), which was subdivided into 6.7% with good score and 86.3% with fair score, whereas in group 2, it was 70.13 ± 5.5 (range, 58–78), which was subdivided into 26.8% with good score and 73.2% with fair score. Results There were statistically significant improvements in both groups, with no difference in their outcomes. Both groups showed significantly improved hindfoot and midfoot motion and positioning. Hindfoot range of motion was preserved. Radiography also revealed significant improvements. Conclusion Both procedures are valid options for the surgical management of idiopathic symptomatic flatfoot in pediatric patients.

Flatfoot in Children: A Review of Literature (Point of View)

Flatfoot (pes planus) is described as a reduction or absence of the Medial Longitudinal Arch (MLA) of the foot, with or without additional deformities of the foot and ankle. It is a very common orthopedic manifestation in infants and children and usually resolves by adolescence. Flatfoot is usually flexible and painless with no functional compromise so that described as physiologic. In some rare cases flatfoot can become painful or rigid and may be a sign of pathology such as vertical talus or tarsal coalition. Although it is very common, there is no standard definition and no universally accepted classification system for pediatric flatfoot. Furthermore there are no large, prospective studies comparing the natural history of flatfoot in response to various treatments during the developmental period. Current literature suggests that it is safe and appropriate to simply observe an asymptomatic child with flatfoot. Painful flexible flatfoot may benefit from orthopedic intervention such as physical therapy, orthosis or sometimes a surgical procedure.
