Purpose: The purpose of this study was to evaluate pressure distribution on the foot with the use of custom made foot orthosis and evaluate influential factors in young people using custom orthosis. Materials and Methods: 22 individuals comprised of young males and females were evaluated by radiograph, pedobarograph, and satisfaction rate and VAS score. The data was analyzed statistically to find influential factors for satisfaction after wearing the foot orthosis. Results: Around 50% of participants were satisfied in wearing the custom made foot orthosis. Initial VAS score of satisfaction of $36.2{\pm}19.7$ improved to $73.1{\pm}15.6$ after application of foot orthosis. There was a statistically significant difference. Talo-second metatarsal angle on AP radiograph after orthosis application was significantly related to satisfaction. On analysis of pedobarograph data, total contact area was increased and weight distribution was transferred medially on ambulation with the orthosis applied. Conclusion: Before designing the foot orthosis, individual foot factors such as foot anatomy and foot pressure distribution should be evaluated for foot comfort and better patient satisfaction.

Purpose: The purpose of this study was to evaluate the result of open wedge osteotomy at the anterior calcaneus with iliac bone graft (Evans procedure) for symptomatic flexible flatfeet in children. Materials and Methods: A retrospective study was conducted between October 1995 and September 2002. Six cases in 3 patients who had symptomatic flexible flatfeet was included. Follow-up averaged 39.5 months. We evaluated the patients' satisfaction by Mann and Reynolds scorring and compared the radiographic results between preoperative and final radiography. Results: The satisfaction outcomes at the last follow-up were excellent in five and good in one. The mean lateral talo-first metatarsal angle was improved from $-20^{\circ}$ to $-3^{\circ}$. The mean calcaneal inclination angle was improved from $8.5^{\circ}$ to $20.8^{\circ}$. The talo-navicular coverage angle was improved from $47.5^{\circ}$ to $7.5^{\circ}$. In one case, we found the subluxation of calcaneocuboidal jont in postoperative radiography. Conclusion: Open wedge osteotomy at the anterior calcaneus for symptomatic flexible flatfeet in children was considered as one of the effective treatment methods.

Purpose: This study examined the dynamic peak plantar pressure under the foot areas in those with a functional leg length inequality. Methods: The dynamic peak plantar pressure under the foot areas in an experimental group with a functional leg length inequality (n=20) and a control group (n=20) was assessed a using the Mat-Scan system (Tekscan, USA). The peak plantar pressure under the hallux, 1st, 2nd, 3-4th and 5th metatarsal head (MTH), mid foot, and heel was measured while the subject was walking on the Mat-Scan system. Results: The experimental group had significantly higher peak plantar pressure under all foot areas when the dynamic peak plantar pressure in the short leg and long leg sides was compared. The control group had a significantly higher peak plantar pressure under the 1st, 2nd, 3-4th, and 5th MTH when the dynamic peak plantar pressure in the short leg and long leg sides were compared. The experimental group showed a significantly larger difference in the dynamic peak plantar pressure under the hallux, 1st, 2nd, 3-4th and 5th MTH, mid foot and heel than the control group. Conclusion: A functional leg length inequality leads to an increase in the weight distribution and dynamic peak plantar pressure in the side of the short leg.

In industrial designing of ready-to-wear shoes, one important factor to consider is that the population has diverse fooot shapes as well as foot length. The general shape of a foot could be represented by "foot ratio", i.e. the ratio of width to length. In this study, we measured several dey aspects of young Korean men's foot, and compared the results with their shoe sizes and general foot shapes. To this end, 172 male subjects were categorized according to their shoe size (small, medium, large) or foot ratio (wide, narrow, intermediate). The statistics of this survey indicated that the people with narrow foot shap have significantly greater foot length compared with the one having wide foot shape. Conversely, subjects having wide foot shape manifested significantly greater foot and ankle girth as well as significantly greater foot breadth. However, different foot shape groups showed no significant differences in heel width, heel ankle girth, instep height, and malleolus height. On the other hand, subjects wearing larger shoe size showed significantly larger foot measurements except instep and ankle heights, whereas subjects with shoe sizes 260 and below measured significantly more narrow heel and lateral metatarsal breadths. The deviation between foot length and dress shoe size(length) was greater in groups with wide foot shape and in groups wearing large shoe sizes. The results of this survey indicated that the subjects with wide foot shape apparently choose a size or two larger shoes for them as a compromise for a better breadth fit.eadth fit.

Objects：The purpose of this study is to investigate the values of foot pressure of the stance phase during a gait cycle in hemiplegic gait. Method：42 patients who had a stroke and 42 healthy adults were evaluated by the RSscan system to analyze the stance phase of hemiplegic gait. The stance phase was evaluated as plantar foor pressure. Results：1) Foot plantar pressure of toe area, affected side and less affected side showed low distribution of the plantar foot pressure which is lower than plantar foot pressure of normal adults(p<0.05). 2) Foot plantar pressure of metatarsal area, showed significantly differences among hemiplesic patient's affected side and less affected side and distribution of plantar foot pressure of normal adults(p<0.05). 3) Foot plantar pressure of heel area, hemiplesic patients' affected side and less affected side showed lower distribution of the plantar foot pressure than plantar foot pressure of normal adults(p<0.05). Conclusion：The results of this study suggest that not only affected side but also less affected side in hemiplegic patients showed significantly differences in distribution of the plantar foot pressure of normal adults.

The forefoot reconstruction is a challenging field for plastic surgeons. Weight bearing tolerability and stability are important factor of choosing reconstruction methods, but cosmetic aspect has to be considered. 51 year old man visited our clinic with extensive degloving injury on right forefoot by roller. The soft tissue defect started from metatarsal area to the toe tip including nails. We harvested the anterolateral thigh flap and transferred it to the forefoot defect area with nerve coaptation. The flap was successful without skin necrosis or other complications. Secondary flap debulking surgery was performed after ten months from initial operation. Patient was satisfied with functional and cosmetic outcomes. The patient was able to wear shoes and walk with adequate sensory recovery. As there is few report about reconstruction of forefoot soft tissue defects, we report a unique case of the anterolateral thigh innervated free flap reconstruction in degloving injury.

A 2-year-old, 440 kg, thoroughbred gelding showed a lameness grade of 3 out of 5, as well as swelling and heating on the proximal interphalangeal joint (PIPJ). Periarticular new bones due to the arthritis were observed on performing radiography and ultrasonography. PIPJ arthrodesis was performed under general anesthesia. With the PIPJ open, the articular cartilage was removed by using curette, chisel, and mallet. Arthrodesis was performed with a PIP plate and two additional transarticular cortex screws inserted in lag fashion. A cast was placed over the limb distal from the proximal metatarsal bone. At 6 months after surgery, complete union of the PIPJ was confirmed by radiography, and the incision site was well closed. Based on the outcome, a PIP plate with two additional transarticular cortex screws inserted in lag fashion is recommended as a method for treating osteoarthritis of the PIPJ in horses.

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.
