Objective : The purpose of this study was to investigate mean plantar foot pressure, maximum plantar pressure and ground reaction force, and center migration path of pressure according to the type of trekking shoes for the development of shoes. Method : Subjects of the study averaged $22.10{\pm}2.05years$ of age. Their average height was $169.27{\pm}7.62cm$ and their average weight was $64.34{\pm}10.22kg$. The method of this study was administered measuring 50 steps, at once, 3 times at a speed of 4 km/h and using the data of 30 steps. Pedar-X system measured the mean foot pressure, maximum foot pressure, mean maximum force, and center migration path of pressure by subjects' position while walking. Statistical analysis was performed by SPSS 23.0 using a paired t-test. Results : Results of the study showed Nestfit trekking shoes lower foot pressure of both feet in mean foot pressure and maximum foot pressure. Nestfit trekking shoes showed high ground reaction force (p<.001) in the midfoot, and low mean ground reaction force in the rearfoot. The center migration path of pressure showed the Nestfit trekking shoes were more stable than flat insole trekking shoes. Conclusion : It can be concluded that wearing Nestfit trekking shoes spreads pressure efficiently and induces walking stability because Nestfit trekking shoes spread the pressure of the forefoot and rearfoot to the midfoot and the center migration path of pressure shows regularly.

Purpose: Open fractures of the foot and ankle require prompt repair of the wound due to the complexity of anatomy, insufficiency of soft tissues and inadequate blood supply. Early flaps and skin grafts are used for this purpose yet general condition of the patient as well as local wound environment often precludes such treatment options. Vacuum- Assisted Closure (VAC) is recently being used in such cases. This study was done to validate the use of VAC together with silver antimicrobial dressing materials in contaminated open fracture wounds. Materials and Methods: We have selected 10 patients with Gustillo-Anderson type III open fractures of the foot & ankle treated with VAC and silver antimicrobial dressing materials from March 2007 to January 2008. The relationship between duration of treatment with wound size, contamination, and degree of soft tissue damage was analyzed. Results: The average age of patients was 36.6 years. The average amount of VAC application time was 23.4 days. Silver dressing materials were used for 16.8 days. Average wound healing time was 51.9 days. Statistically significant relationship was found between wound size, VAC application time and silver dressing material application time. No complications such as osteomyelitis were found after treatment. Conclusion: VAC technique is recently being used in open fractures with wide skin and soft tissue defects, producing good results. A wide array of dressing materials such as silver dressing is in development. We have incorporated the VAC technique together with silver dressing materials in the treatment of open fractures and achieved complication free results.

Purpose: To investigate the results of surgical treatment of the symptomatic accessory navicular in adolescent. Materials and Methods: 11 patients who were 11-16 years old with symptomatic accessory navicular were identified between 2001 and 2009. Six cases were diagnosed after trauma and 8 cases were diagnosed by accident with painful bony protrusion on medial aspect of foot. In cases after at least 3 months of ineffective conservative treatment, patients were treated by resection of accessory navicular and reattachment of tibialis posterior tendon to the apex of the medial longitudinal arch using periosteum and ligamentous soft tissue without transposition of its course. And then short leg cast was applied for correction of the flat foot (if it is combined) which was molded into the longitudinal arch with the talonavicular joint released and foot inverted during about 6 weeks. Results: All were type II accessory navicular without tibialis posterior tendon lesions. In most cases pain was improved, results were excellent in seven and good in four. Calcaneal pitch angle and talus-first metatarsal angle was improved about $4.64^{\circ}$ and $5.79^{\circ}$ in average. Conclusion: Symptomatic accessory navicular in adolescent might not be associated with the tibialis posterior tendon lesions. The surgical treatment composed of excision of the accessory navicular with simple replication of the tibialis posterior tendon without altering its course led to good results in most cases. The procedure has a low rate of complications. And it is easy to be performed with a good satisfaction.

The Work-Related Musculoskeletal Disorders (WMSDs) can be occurred by various factors such as repetition, forceful exertions and awkward postures. Especially, occurrences of the WMSDs on the waist and lower limb are reported in workplaces, demanded standing postures for a long time, in service and manufacturing industry. The static and standing postures without movement for a long time increase work loads to the lower limb and the waist. Accordingly, anti-fatigue mat or anti-fatigue insole is used as a preventing device of the WMSDs. However anti-fatigue mats are limited in space and movement. In this study, multi-elastic insoles are designed and shown the effects of the workload reduction for a long time under the standing work. The foot pressures and EMG (Electromyography) are measured at 0 hour and after 2 hours by 6 health students in their twenties. The 6 prototype insoles are designed with three elastic (Low, Medium and High). These insoles are compared with no insole (insole type 7) as control group. The EMG measurement was conducted to waist (erector spinae muscle), thigh (vastus lateralis muscle) and calf (gastrocnemius muscle). The foot pressure is analyzed by mean pressure value and the EMG analysis is investigated through MF (Median Frequency), MPF (Mean Power Frequency) and ZCR (Zero Crossing Rate). The results of the foot pressure show that the multi-elastic insoles had smaller foot pressure value than that of no-insole. Moreover, Insole 2 and Insole 3 have the smallest increasing rate in foot pressure. The EMG results show that the multi-elastic insoles had smaller EMG shift value than that of no-insole in 2 hour, and then shift value shows the smallest value in Insole 2. Therefore, this study presents that the multi-elastic insoles have reducing effects of the work load for a long time standing work in both side of foot pressure and EMG.

Purpose: The purpose of this study was to investigate treatment types and the status of referral to home care services for patients with diabetic foot. Methods: A retrospective survey was conducted by reviewing medical records from January to December in 2008 at a university hospital. The subjects were 76 patients at the age of 20 years or older who were admitted, had home care services, or received outpatient care for diabetic foot. The data were analyzed using descriptive statistics. Results: Among the total of 9,317 patients diagnosed with diabetes, 5.03% (n=469) had diabetic foot. Admission (81.6%) was the most frequently used treatment type followed by outpatient care only (7.9%) and hemodialysis only (10.5%). Of the 76 admission cases, 44.9% received post-discharge care at outpatient clinics, 20.5% had both outpatient and home care services, and 16.7% were transferred to other hospitals. Readmission rate after discharge was 15.6% for one year. Conclusion: This study suggests referral to home care services should be encouraged to provide effective follow-up care to patients with diabetic foot after discharge from a hospital.

Objective : A study and development of Korean Bobsleigh athletes's shoe which considers their physical condition has yet to be completed. So this study examines the effects of running shoes used by athletes based on plantar pressure and sprint time in order to provide raw data for the development of bobsleigh shoes suitable for Koreans. Method : The study selected seven bobsleigh athletes as subjects and selected three pairs of spiked running shoes from three companies, which will be referred to as Company N (Type A), Company A (Type B), and Company M (Type C). To analyze sprint time and plantar pressure for each shoe, the subject of the study were instructed to wear the selected shoes and to drag a sled at maximum sprint for 15 meters for 15 meters for in each condition that would be in real bobsleigh competitions. Results : The average sprint intervals for each athlete in each pair of shoes revealed Type C produce the fastest sprint in the order of Type C < Type A< Type B. Shoe Type C also had the largest contact area in order of Type C > Type B > Type A (p<.01). None of the three shoe types seem to yield a distinct advantage in terms of maximum average pressure or maximum pressure. Conclusion : In the future, functional analysis should be carried out by comparing the material properties, hardness, and toe spring of shoes based on the Type C shoe from Company M in order to develop bobsleigh shoes suitable for Koreans.

Purpose: To evaluate and compare the outcome between interlocking IM nailing and LCP fixation in the treatment of distal metaphyseal tibial fracture. Materials and Methods: From January 2000 to December 2007, 17 patient were treated by interlocking IM nail and 13 patient were treated by LCP fixation for distal metaphyseal tibial fracture. Results: According to AO classification, there were 2 type A1 fracture (12%), 6 type A2 fracture (36%), 3 type A3 fracture (18%), 4 type B1 fracture (24%), 1 type B3 fracture (6%), 1 type C1 fracture (6%) in interlocking IM nailing group and 1 type A2 fracture (7.7%), 2 type A3 fracture (15.4%), 3 type B1 fracture (23%), 3 type B2 fracture (23%), 3 type C1 fracture (23%), 1 type C2 fracture (7.7%) in LCP fixation group. The clinical functional outcome (according to AOFAS score) is 75.6 point in IM nailing group and 81.5 point in LCP fixation group. In IM nailing group, 65% of patient showed satisfactory result and In LCP fixation group, 77% of patient showed satisfactory result. Conclusion: There is no difference on clinical results between IM nailing and MIPPO (minimal invasive percutaneous plate osteosynthesis) group in the treatment of distal tibia fracture. But MIPPO group have higher subjective satisfactory score and less complication rate. The weakness of our study is a small case number and limited follow-up and we believe a better designed prospective study will be needed.
