Subtalar repositional arthrodesis for adult acquired Flatfoot : Adult acquired Flatfoot
Clinical Orthopaedics and Related Research, 1999Co-Authors: Heidi M. Stephens, Arthur K. Walling, J. D. Solmen, C. J. TanksonAbstract:Arthrodesis of the subtalar joint is well recognized treatment option for moderate or severe Flatfoot associated with adult acquired Flatfoot secondary to posterior tibial tendon dysfunction. The success of the subtalar arthrodesis is dependent on restoration of normal bony relationships in the hindfoot and midfoot. For this reason, a distinction is made between a repositional arthrodesis and the traditional in situ type of arthrodesis. An in vitro study of the adult acquired Flatfoot identifies an anteroposterior subluxation of the subtalar articulation that can be corrected durably and reliably through a repositional talocalcaneal arthrodesis. Intraoperative reduction techniques are useful in obtaining reduction of the peritalar subluxation. There are certain clinical features that help identify patients with Flatfoot deformities who are good candidates for subtalar fusion. As the pathoanatomy of the Flatfoot deformity is better elucidated, treatment techniques are modified to better address the key elements of the deformity. A repositional subtalar arthrodesis was shown to produce excellent correction in a moderate to severe in vitro Flatfoot example in the authors' clinical series.

Operative treatment of Flatfoot with talocalcaneal coalition.
Clinical orthopaedics and related research, 2003Co-Authors: Sandro Giannini, Francesco Ceccarelli, Francesca Vannini, Elena BaldiAbstract:Rigid Flatfoot or peroneal spastic Flatfoot often is associated with a congenital fibrous, cartilaginous, or osseous union of two tarsal bones or more, potentially causing great difficulties in its treatment. Since 1996, 12 patients (14 feet) with painful Flatfoot and restricted motion of the hindfoot attributable to talocalcaneal coalition, were treated by resection of the coalition and subtalar arthroereisis by a bioreabsorbable implant. The results were evaluated by the ankle hindfoot clinical rating system of the American Orthopaedic Foot and Ankle Society. These clinical results also were evaluated statistically. Radiographs and computed tomography scans were taken preoperatively and postoperatively. Eight (57.1% of patients) had excellent results, three (21.4% of patients) had good results, and three (21.4% of patients) had fair results. No poor results, or subjective or objective complications were reported. On the basis of these early results, arthroereisis by implanting a bioreabsorbable device after removal of the tarsal coalition, seems to be an effective procedure for the treatment of symptomatic Flatfoot associated with talocalcaneal coalitions: correcting the relationship between talus and calcaneus, restoring the alignment of the hindfoot, and reducing pain.

An investigation of the factors affecting Flatfoot in children with delayed motor development
Research in developmental disabilities, 2014Co-Authors: Kun Chung Chen, Chih Jung Yeh, Li Chen Tung, Jeng Feng Yang, Chien Hung Tung, Chun-hou WangAbstract:This study investigated the prevalence of Flatfoot in children with delayed motor development and the relevant factors affecting it. In total, 121 preschool-aged children aged 3-6 with delayed motor development (male: 81; female: 40) were enrolled in the motor-developmentally delayed children group, and 4 times that number, a total of 484 children (male: 324; female: 160), of gender- and age-matched normal developmental children were used as a control group for further analyses. The age was from 3.0 to 6.9 years old for the participants. The judgment criterion of Flatfoot was the Chippaux-Smirak index >62.70%, in footprint measurement. The results showed that the prevalence of Flatfoot in children with motor developmental delay was higher than that in normal developmental children, approximately 58.7%, and that it decreased with age from 62.8% of 3-year-olds to 50.0% of 6-year-olds. The results also showed that motor-developmentally delayed children with Flatfoot are at about 1.5 times the risk of normal developmental children (odds ratio=1.511, p=0.005). In addition, the prevalence of Flatfoot is relatively higher in overweight children with delayed motor development, and that in obese children is even as high as 95.8% (23/24). Children with both excessive joint laxity and delayed development are more likely to suffer from Flatfoot. The findings of this study can serve as a reference for clinical workers to deal with foot issues in children with delayed motor development.

Change in Flatfoot of preschool-aged children: a 1-year follow-up study
European journal of pediatrics, 2012Co-Authors: Kun Chung Chen, Chih Jung Yeh, Li Chen Tung, Jeng Feng Yang, Jing Fu Kuo, Chun-hou WangAbstract:The main purpose of this study is to investigate the changes in the signs of Flatfoot of preschool-aged children in a 1-year follow-up study. This study performed follow-up on a total of 580 preschool-aged children (boys, 297 children; girls, 283 children) with a median age of 54 (range 36–71 months), and the average follow-up period was 11.8 months. This study used the Chippaux–Smirak index (CSI) of footprint as the assessment tool, and CSI > 62.70 % was used as the standard for determining whether preschool-aged children suffered from Flatfoot. The results showed that the signs of Flatfoot of preschool-aged children improved with increasing age. At the 1-year follow-up, the average CSI was 5.1 % lower, and the proportion of children with Flatfoot was 14 % lower. The follow-up on the change in the signs of Flatfoot showed that 37.6 % of the children originally with Flatfoot had improved to normal, verifying that Flatfoot indeed improves with increasing age. However, the results also showed that 9.9 % of the children who originally had normal feet had developed Flatfoot with increasing age, which deserves subsequent investigation. The results of the follow-up also showed that children who were relatively younger, male, obese, and experiencing excessive joint laxity were more likely to experience the signs of Flatfoot. Conclusion: The 1-year follow-up found that some preschool-aged children with Flatfoot may develop normal feet, while children with normal feet may begin to experience the signs. Relevant factors affecting Flatfoot in preschool-aged children continue to require further clarification.

Relevant factors influencing Flatfoot in preschool-aged children
European journal of pediatrics, 2010Co-Authors: Kun Chung Chen, Chih Jung Yeh, Li Chen Tung, Jeng Feng Yang, Shun Fa Yang, Chun-hou WangAbstract:The aim of this study was to discuss the influence of age, gender, obesity status, joint laxity, and the W-sitting habit on Flatfoot in preschool-aged children. A total of 1,598 children (833 boys and 765 girls) between 3 and 6 years of age from kindergartens in the central area of Taiwan were studied. The children were divided into a normal group (n = 733), a unilateral Flatfoot group (n = 266), and a bilateral Flatfoot group (n = 599), and a multinomial logistic regression model was used to analyze the data. The prevalence of Flatfoot decreased significantly with increasing age: 54.5% of 3-year-old but only 21% for 6-year-old children had bilateral Flatfoot. In the bilateral Flatfoot group, the risk decreased with increased age, increased with increasing weight beyond the normal range, and was higher for boys than girls. Age and obesity status were not significantly influential in the unilateral Flatfoot group. Children with higher joint laxity and a habit of W-sitting also experienced higher risk in both Flatfoot groups. In conclusion, this study demonstrates a significant association of age, gender, obesity status, joint laxity, and the W-sitting habit with the bilateral Flatfoot in preschool-aged children. Children with unilateral Flatfoot differ from those with normal feet and bilateral Flatfoot. It is suggested that the unilateral Flatfoot deserves special attention in future studies.
