- Kinematic differences between neutral and flat feet with and without symptoms as measured by the Oxford foot model. [Journal Article]
- GPGait Posture 2018 Oct 13; 67:213-218
- CONCLUSIONS: The results suggest that foot motion in the transverse plane is closely associated with the presence of symptoms in flat feet and that this is accompanied by changes in the kinematics of the ankle, knee, and hip.

This study aimed to find the correlation between conventional Arch Index (AI) measurements and our prototype of a simplified insole-based plantar pressure measurement system and to find out the effective plantar pressure sensor position. Twenty-one subjects participated in this study, which was divided into two groups: 10 subjects with flatfoot and 11 subjects with normal foot. Five force sensitive resistance sensors were used on this prototype using Arduino as the data acquisition device. Two types of trials, namely static and dynamic, were conducted to validate our system against the ink-type AI measurement as a golden standard. The results showed that in the static trial, there was a high linear correlation with the medial arch sensor configuration, while in the dynamic trial, there was a high linear correlation in the medial arch sensor configuration and sensor 5 configuration. This study showed that both static and dynamic tests using the self-developed device could effectively determine most of the flatfoot subjects and suggests that in the future, it can be applied in clinical applications because of its advantages when compared to the expensive-high tech graphic input board and conventional tools, like ink-type based measurements.
- Long-Term Results of the "Horseman" Procedure for Severe Idiopathic Flatfoot in Children: A Retrospective Analysis of 41 Consecutive Cases With Mean 8.9 Year Duration of Follow-Up. [Journal Article]

The "horseman" procedure is a surgical technique used to correct the talocalcaneal joint displacement of severe idiopathic flatfoot in children while maintaining the reduction with a temporary talocalcaneal screw. While this technique has been used since the early 1960s, very little has been reported on its results. Our objectives were to estimate the correction, functional results, and postoperative complications of the "horseman" procedure. We conducted a retrospective study on 23 consecutive patients (41 cases) who underwent the "horseman" procedure for a talocalcaneal joint displacement. Mean follow-up was 8.9 (range 1 to 28) years, and 8 patients (12 feet) had reached bone maturity at last follow-up. Mean age at surgery was 6.6 (range 4 to 9.5) years. At last follow-up, all the patients were asymptomatic except 2 [8.7%] (4 [9.8%] cases). The talocalcaneal divergence on anteroposterior and lateral radiographic views was reduced by 8.9° and 11.4°, respectively, after the surgery, and the correction was maintained with loss of 0.7° and 2.9°, respectively, at final follow-up. The talonavicular coverage angle was reduced by 25° without loss of correction at last follow-up. The calcaneal pitch angle did not change after the surgery. Mean American Orthopedic Foot and Ankle Society score increased from 88.7 of 100 (63 of 100 to 93 of 100) preoperatively to 99 of 100 (97 to 100 of 100) at last follow-up. No major complication occurred. The "horseman" procedure allows an immediate and lasting correction of severe idiopathic flatfoot in children.
- Validation of normalized truncated navicular height as a clinical assessment measure of static foot posture to determine flatfoot in children and adolescents: A cross sectional study. [Journal Article]

- CONCLUSIONS: NTNH is a valid and diagnostically accurate clinical measure of static foot posture in children and adolescents.
- Acute effect of foot orthoses on frequency domain of ground reaction forces in male children with flexible flatfeet during walking. [Journal Article]
- FFoot (Edinb) 2018 May 29; 37:77-84
- CONCLUSIONS: Foot orthoses decreased medio-lateral ground reaction force frequency in the non-dominant limb, but have little effect on other ground reaction frequency components. Decreased frequency phenomena due to foot orthoses in children with flatfeet suggest an attenuation of ground reaction forces during walking. Frequency domain analysis thus offered new insights on the gait improvements associated with using foot orthoses.

Posterior tibial tendon dysfunction (PTTD) is a progressive disorder and a common cause of adult acquired flatfoot deformity, and forefoot varus is a frequent component in advanced cases. The author proposes peroneus brevis-to-longus transfer as an additional step to correct the forefoot varus component of stage II-A posterior tibial tendon dysfunction. We have performed this dynamic correction of forefoot varus in 12 patients at our institution, and observed promising clinical and radiographic improvement. It is a soft tissue procedure that avoids additional incisions and represents a favorable alternative to more demanding techniques, such as osteotomy or arthrodesis.

- FAFoot Ankle Surg 2018 Sep 12
- CONCLUSIONS: There is increased mobility in the medial longitudinal arch joints in stage II posterior tibial tendon dysfunction flatfoot and the medial arch angle change under loading causes displacement not only at hindfoot joints but also involve midfoot and forefoot joint.
