The purpose of this study is to assess the radiographic effects of normal person with contact laterally wedged insoles with strapping of varying elevations. Eight person who were randomized into group according to their birth dates and wedge elevation, participants wore contact laterally wedged insoles with strapping with elevation of 9, 15, 21mm. Standing radiographs were used to analyze the femorotibial angle for each subject, The result of repeated measures ANOVA's reveled that laterally wedged insoles with strapping of varying elevations produced significantly the femorotibial angle. The degree of change in femorotibial angle with the insole with strapping was effected by the tilt of the lateral wedge(P<0.05). We suggest that these results may be beneficial for manufacturing foot orthotic devices, such as wedged insoles, to control medial and later compartment forces in the knee varus-valgus deformity.

Forefoot disorders are often seen in clinical practice. Forefoot deformity and pain can deteriorate gait function and decrease quality of life. This review presents common forefoot disorders and conservative treatment using an insole or orthosis. Metatarsalgia is a painful foot condition affecting the metatarsal (MT) region of the foot. A MT pad, MT bar, or forefoot cushion can be used to alleviate MT pain. Hallux valgus is a deformity characterized by medial deviation of the first MT and lateral deviation of the hallux. A toe spreader, valgus splint, and bunion shield are commonly applied to patients with hallux valgus. Hallux limitus and hallux rigidus refer to painful limitations of dorsiflexion of the first metatarsophalangeal joint. A kinetic wedge foot orthosis or rocker sole can help relieve symptoms from hallux limitus or rigidus. Hammer, claw, and mallet toes are sagittal plane deformities of the lesser toes. Toe sleeve or padding can be applied over high-pressure areas in the proximal or distal interphalangeal joints or under the MT heads. An MT off-loading insole can also be used to alleviate symptoms following lesser toe deformities. Morton's neuroma is a benign neuroma of an intermetatarsal plantar nerve that leads to a painful condition affecting the MT area. The MT bar, the plantar pad, or a more cushioned insole would be useful. In addition, patients with any of the above various forefoot disorders should avoid tight-fitting or high-heeled shoes. Applying an insole or orthosis and wearing proper shoes can be beneficial for managing forefoot disorders.

Background : Klippel-Trenaunay-Weber syndrome (KTS) is a rare congenital medical condition characterized by complex vascular malformation. KTS consists of a classic triad of capillary malformation (hemangioma), venous malformations and bone or soft tissue hypertrophy causing limb asymmetry. The aim of this report is to describe management for gait disturbance and foot pain in a Patient with KTS using custom-made total contact insole. Case presentation : A 32-year-old man with KTS presented with a 3-year history of gait disturbance on hard surface due to right first toe pain and Achilles tendon tightness. The patient had soft tissue hypertrophy, varicose veins and port-wine stains over the right lower limb associated with KTS. True leg length discrepancy was 2 cm. We prescribed custom-made total contact insole to protect his deformed foot and correct leg length discrepancy. The insole of right side included wedge shaped heel lift and the insole of left side included full length lift to add extra support on unaffected side. Also, we provided compression stocking and physiotherapy including manual lymphatic drainage for lymphedema and stretching exercise for tightness in right lower extremity. At 3 years follow-up, postural alignment including pelvic obliquity was improved using a custom-made total contact insole. The degree of scoliosis and foot pain were also reduced. Conclusion : An individualized and multidisciplinary approach is essential regarding the complexity of comorbidities in patients with KTS. For patients with KTS, orthotic management should be considered to prevent and correct deformities related to KTS. Active orthotic management, compression stocking and physiotherapy can enhance the quality of life and function in patients.

This study was conducted on male college students with pronated foot to measure the foot pressure by having them wear three kinds of mid-sole wedge ($0^{\circ}$, $5^{\circ}$, $10^{\circ}$). Maximum force, foot contact area, mean pressure and peak pressure were measured using a foot pressure distribution measuring instrument. And the surface of the foot sole was divided into 10 areas. Regarding maximum force, there were statistically significant difference in the area 3 of the middle foot(p<.05). Regarding the foot contact area, it appeared broad in the outside area(1, 3, 5) of the foot according to mid-sole wedge, and there was statistically significant difference in the area 1 of the rear foot(p<.05) and the area 3 of the middle foot(p<.05). Mean pressure by foot area decreased in the inside of the foot according to mid-sole wedge, and there was statistically significant difference in the area 2 of the rear foot(p<.05) and the area 3 of the middle foot(p<.05). Regarding the peak pressure by foot area, the pressure roughly decreased in the inside area(2, 4, 7) of the foot according to mid-sole wedge, and there was statistically significant difference in the area 1(p<.05), 2(p<.05) of the rear foot and the area 3 of the middle foot(p<.05).
