The aim of the current study was to understand the importance of the joint alignment following triple arthrodesis by analysing the contact characteristics in a normal and arthritic ankle joint using a patient-specific numerical model developed using open source software. The alignment of the hindfoot with respect to tibia is calculated from CT scans and the ankle joint model was numerically analysed for neutral, valgus and varus positions in both normal and arthritic conditions. The contact area, the magnitude and distribution of the contact pressure on the articular surface of the talar dome was evaluated using a cell-centred Finite Volume Method implemented in open-source software OpenFOAM. It was found that all positions of the hindfoot predict higher lateral pressures during heel strike. The varus position predicts the maximum increase in lateral pressures. Comparing the valgus and neutral positions, although the neutral position predicts 9.1 % higher increase in lateral pressures during heel strike than valgus, it predicts 33.6 % decrease in pressures during heel-rise and the distribution is more medial during toe-off. In the case of arthritic ankle, it could be observed that the neutral and varus hindfoot fusion positions result in a concentrated increase of lateral pressures in heel strike and flat-foot. In the case of toe-off, the neutral alignment results in an increase of 62.3 % in the contact pressures compared to the arthritic pressure of the unfused foot and is 20.8 % higher than the valgus alignment. The study helps to conclude that the fusion is more beneficial at the neutral position of the hindfoot for the patient specific ankle. However, the 5° valgus position of hindfoot alignment could be more beneficial in the arthritic ankle. Patient-specific approach to the placement of the hindfoot with the help of numerical analysis could help address the issue of ankle degradation following arthrodesis.

INTRODUCTION AND OBJECTIVE
Subtalar arthroereisis is a procedure commonly performed in children with flat feet. The procedure is performed when conservative treatment did not have the desired effect,or when the patient's abnormal symptoms are very severe and make it difficult for them to function normally in daily life. The aim of this study was to assess whether subtalar arthroereisis and physiotherapy improve the quality of life among children with flat feet.
MATERIAL AND METHODS
The study comprised 79 patients (140 operated feet) diagnosed with a flat foot defect who underwent a subtalar arthroereisis procedure. A self-administered questionnaire and a shortened version of the standardised WHOQOL-BREF questionnaire were used in the research.
RESULTS
The study confirmed that the patients' quality of life after surgery was high in all the areas regarding the somatic, psychological, social and environmental domains. In the group of children assessed 13-24 months after surgery. it was also found that rapid fatigue after exercise (30% ± 9%) and Achilles tendon contracture (7% ± 4%) were significantly reduced. The results of the study confirmed that subtalar arthroereisis contributes to a decreased demand for orthoses in children (9% ± 6%) and for orthopaedic footwear (11% ± 5%) than before surgery.
CONCLUSIONS
The employment of subtalars arthroereisis has a positive effect on the quality of life of children with flat feet. The surgery contributes to a reduction in pain and other abnormal symptoms that are associated with flat feet. In addition, physiotherapy performed after the procedure had a positive effect on the healing process and contributed to the improvement of the children's quality of life.

Medial displacement calcaneal osteotomy (MDCO) is the standard procedure for flatfoot. We investigated the effect of MDCO on the foot using a finite element analysis. Foot models were created from computed tomography data of 8 patients with flat feet. MDCO was performed on each model with bone translation distance of 4, 8, and 12 mm. The morphological changes, plantar pressures, and stress percentage on the talocrural and subtalar joints were evaluated before and after surgery. Morphological evaluation showed improvement in the medial longitudinal arch. The stress percentage of plantar pressure in the medial area decreased, and the stress percentage of plantar pressure in the mid- and lateral forefoot area increased. At the talocrural joint, the medial and middle stress percentage increased, while the lateral and posterior stress percentage decreased. In the subtalar joint, the stress percentage in the middle subtalar joint increased and that in the posterior subtalar joint decreased. Within the posterior subtalar joint, the anterior and medial stress percentage increased, while the posterior and lateral stress percentage decreased. Preoperative simulation using the finite element analysis may be useful in understanding postoperative morphological changes and loading conditions to perform patient-specific surgery.

BACKGROUND
Flatfoot (pes planus) is a decrease or loss of longitudinal medial arch height. The cause of symptomatic flatfoot occurring in adolescents is still unclear. In this study, the relationship between adolescent pes planus and foot bone shape was investigated. For this purpose, the volume and superficial area data of the foot bones of adolescent individuals with flatfoot deformity and individuals without any foot deformity were compared.
METHODS
Between September 2022 and June 2023, 30 individuals with adolescent pes planus with a medial arch angle greater than 145 degrees and 30 individuals without any foot deformity were included in the study. Computed tomography (CT) images of the participants' feet were obtained with a General Electric brand IQ model 32 detector CT device with a section thickness of 0.625 mm in accordance with the bone protocol. Using the 3D Slicer program on CT images, foot bones were segmented and the volume and surface area ratios of each foot bone were determined.
RESULTS
Cuneiforme mediale and cuneiforme intermediale volume ratios in individuals with flatfoot deformity decreased by 14% and 24%, respectively, compared with the control group (P<0.05). Cuneiforme mediale and cuneiforme intermediale superficial area ratios were found to be 10% and 30% lower in the flatfoot group compared with the control group, respectively (P<0.05). There was no difference in the volume and superficial area ratios of other foot bones between the groups (P>0.05).
CONCLUSIONS
The study results suggest that symptomatic adolescent flatfoot deformity may be associated with developmental anomalies of the os cuneiforme mediale and os cuneiforme intermedium.

Observational Study
The aim of this study was to investigate the effect of pes planus level on counter movement jump (CMJ) performance parameters in amateur female and male volleyball players. In this context, amateur volleyball players aged between 18 and 23 years actively playing in the university school volleyball team were included in the study. Pes planus levels of the participants were analyzed using the navicular drop test (NDT). My Jump Lab application was used for CMJ measurement. Within the scope of CMJ, the participants' jump height, force, relative force, power, relative power, average speed, take-off speed, impulse, and flying time were analyzed. According to the linear regression results between NDT and CMJ parameters, force in males (t = 12.93, P = .049) and average speed in females (t = -3.52, P = .017) were significantly associated with NDT. NDT was similar in men and women (P > .05). However, all CMJ parameters were highly different between genders (P < .001). In the correlation analysis between sport age and physical characteristics and CMJ parameters; height (r = .386, P = .046), weight (r = .569, P = .002), leg length (r = .389, P = .045), foot length (r =. 558, P = .005), foot width (r = .478, P = .018), force (r = .407, P = .039), impulse (r = .460, P = .018) parameters, and sport age. The results suggest that the average speed in females and force in males both significantly influenced NDT, highlighting the significance of both factors in predicting NDT scores. Moreover, all CMJ measures showed significant variations between genders, although the NDT scores did not. Furthermore, the correlation analysis demonstrated a strong correlation between a number of physical attributes and CMJ parameters, highlighting the multifaceted nature of athletic performance and indicating the possible impact of these attributes on CMJ results.

OBJECTIVE
Childhood flatfoot and overweight can affect children's quality of life and influence their development, increasing the risk of musculoskeletal problems in adulthood. There is evidence linking overweight to the development of childhood flatfoot. The aim of the study was to assess the relationship between the weight status of school children and their foot posture and to determine whether there are differences between both sexes.
METHODS
A cross-sectional study (2021) in a sample of schoolchildren (n=296, 153 boys and 143 girls, mean age 8.5±2.7) from Colegio San Agustín in Zaragoza was carried out. Foot posture was assessed according to the foot postural index, and weight status was obtained using the body mass index according to the criteria of the International Obesity Task Force. The correlation between weight status and foot posture was analyzed using Spearman's coefficient. The Chi-square test was used to determine the differences between the variables according to sex.
RESULTS
Weight status showed no correlation with foot posture in boys (right foot p=0.095; left foot p=0.067) and girls (right foot p=-0.04; left foot p=0.008). Boys had a higher prevalence of flat feet than girls (boys foot posture index=8; girls foot posture index=7; right foot p<0.036; left foot p<0.009). Boys had higher prevalence of overweight than girls (28.75; 18.18, p<0.027).
CONCLUSIONS
Weight status has no effect on foot posture. The male gender could predispose to the development of flat feet and overweight in childhood.

BACKGROUND
Posterior Tibial Tendon Dysfunction (PTTD) is commonly seen within musculoskeletal care. The condition's prevalence and management is poorly understood. This study aims to demonstrate current practice by multi-professional clinicians across the United Kingdom within the National Health Service.
METHODS
A national (UK) cross-sectional online survey was conducted among multi-professionals who treat PTTD within their NHS practice. The survey covered assessment, management and evaluation. This was shared via social media and professional groups.
RESULTS
Two hundred thirteen surveys were completed, with 153 matching the eligibility criteria. The main respondents were Physiotherapists (48%) and Podiatrists (38%). Ultrasound scanning was used most frequently when considering initial imaging (67%). Many different treatment modalities were used, but a core set of education/advice, foot orthoses, and foot specific as well as general exercise were most commonly chosen. Outcome measures routinely used were pain scale (96/269) and single leg heel raise (84/269), but patient reported outcome measures were not routinely used. The most frequent reason to escalate care was failure to manage symptoms with conservative management (106/123; 86.2%), followed by fixed deformity (10/123; 8.2%).
CONCLUSIONS
This survey provides evidence on current non-surgical management for PTTD from UK NHS practice. It provides a valuable marker for clinicians to use to compare their own practice and can be used in further research as a comparator.

Review
BACKGROUND
Deviation of the foot from the normal posture affects the function of the foot and lower limb and causes lower limb injuries in normal people and athletes. Flat feet or flatfoot deformity are usually associated with pain in the foot area and a decrease in the normal function of the foot, which can negatively affect the sports ability of athletes. Therefore, we aimed to investigate the abnormality of flat feet from training, exercise to therapeutic interventions.
METHODS
Articles were identified by searching five databases: PubMed, Scopus, Google Scholar, Science Direct, and Gate & Pasteur from 2000 to 2022. The keywords were selected specifically and correctly and all the researches and articles related to the title of the article were searched and found. This research was also searched in Persian databases that this database, included: Irandoc, Mag Iran and Noormagz.
RESULTS
Finally, 30 studies met the criteria for entering this study, selected and used to conduct this study.
CONCLUSION
By using the results obtained in the research, which include corrective exercises and therapeutic interventions, especially the use of orthoses and various medical insoles, it is possible to help in the treatment and improvement of this anomaly.

Nicolaides-Baraitser syndrome (NCBRS) is a rare autosomal dominant genetic condition that is characterized by severe intellectual disability, dysmorphic facial features, short stature, sparse hair, and early onset seizures. This diagnosis is established by suggestive clinical findings and the identification of a heterozygous SMARCA2 pathogenic variant by molecular genetic testing. There are not, however, consensus clinical diagnostic criteria for this condition as there are so few documented cases. Here, we present a case of prenatally diagnosed caudal regression with sacral agenesis and congenital vertical talus (rocker bottom feet) that was ultimately found to have a de novo SMARCA2 pathogenic variant. The patient had an amniocentesis with normal karyotype and microarray followed by failed direct rapid whole exome sequencing (WES) due to maternal cell contamination. She elected for termination of the pregnancy based on the clinical prognosis of the ultrasound findings; WES revealed a pathogenic variant after her termination. We believe this is the first case of these findings associated with NCBRS. If any future cases of either finding are found in association with a SMARCA2 genetic variant, caudal regression and rocker bottom feet should be included in the spectrum of physical traits associated with this pathogenic variant.

Flatfoot is a structural and functional deformity of the foot that might change ground reaction force variables of gait. Evaluating the components of ground reaction force in three dimensions during gait is considered clinically important. This study aimed to investigate the components of ground reaction force, impulse, and loading rate during gait in people with flexible and rigid flatfoot compared to healthy subjects. 20 young women with flatfoot in two experimental groups (10 with rigid flatfoot and 10 with flexible flatfoot) and 10 healthy women in the control group participated in this study. Ground reaction force components during gait were measured using two force plates. The peak of ground reaction forces, impulse, and loading rate were then extracted. Data were processed and analyzed using MATLAB and SPSS software. One-way ANOVA with a significant level (P˂0.05) was used for statistical analysis. The results showed that peak braking force was higher in the rigid flatfoot group than in the control group (p = 0.016) and the flexible flatfoot group (p = 0.003). The posterior force loading rate was significantly higher in the rigid flatfoot group than in the flexible flatfoot group (P = 0.04). There was no significant difference in vertical loading rate between groups (P˃0.05). Since the maximal posterior ground reaction force was higher in the subjects with rigid flatfoot than in those with flexible flatfoot and healthy subjects, the increase in posterior ground reaction force is associated with an increase in anterior shear force at the knee.
