This study identifies the foot shapes of elderly women by classifying foot type according to the 3D shape of the foot and 2D sole type analyzing individual characteristics. The subjects were 295 elderly women over 60 years of age who live in Gwangju. A foot scanner (K&I Technology $Nexcan^{(R)}$) was used to obtain three-dimensional shapes of feet and a flat bad scanner (HP Scanjet G2410) was used to obtain the two-dimensional shapes of soles. The anthropometric measuring items consisted of 59 items estimated on the right foot of each subject. Data were analyzed by various statistical methods such as factor analysis, ANOVA and cluster analysis using the SPSS 19.0 statistical program. To classify the side type of elderly women's feet, three-dimensional measurement data were analyzed for the 27 measurement items using factor analysis and 6 factors were extracted (inside height and side gradient, ankle thickness, toe height and midfoot size, lateral malleolus height, instep, and heel height and gradient). A cluster analysis resulted in three types: 36.5% belonged to Type 1 (high forefoot and high midfoot), 31.1% belonged to Type 2 (high forefoot and low midfoot), and 32.4% belonged to Type 3 (low forefoot and high midfoot). The distribution was relatively even. For the sole, 8 factors were extracted (ball width and medial foot protrusion, lateral foot protrusion, forefoot and hindfoot length ratio, ball gradient, heel size, toe breadth, lateral ball length, and foot length) and a cluster analysis resulted in three Types (Type H, Type D, and Type A). The largest proportion (42.7%) belonged to Type H, which is the same as the elderly men's case.

The purpose of this study was to determine the fundamental foot measurement data that is essential for a shoes size system of women in their 20~30s according to a survey of Korean hand-made shoes companies. This research on the current situation of shoes companies was done by interviewing and surveying employees of these companies. The subjects for this study were 407 women in their 20s~30s who lived in a metropolitan area, and who wanted to enhance their foot health and prevent injury with a proper shoes size system. They were measured with the 3D scan method in use of 6th Size Korea. The result of this study showed that there is considerable dissatisfaction related to women's shoes and the current foot size system using foot length. The Korean hand-made shoes companies assessed here did not use the KS system, but they recognized the necessity of measuring the foot width and circumference, understanding that doing so properly can decrease the return and repair rate. And current target age for shoes bye the hand-made shoes companies was reported to be approximately 5 years. There were significant results according to ANOVA, factor and cluster analyses according to the age range pertaining to the foot length, circumference and height. Each element was significantly correlated with user's satisfaction. There were 5 factors and 3 clusters represented, and foot circumstance and width were as important as foot length with a range of 5 years.

Tibialis anterior (TA) muscle originates from the lateral surface of tibia and its tendon attaches to the medial cuneiform and base of the first metatarsal. The TA muscle is responsible for both dorsiflexion and inversion of the foot. We present a case of bilateral TA muscle variations that diverge slightly from the current classification systems of this muscle. Recognizing variations such as these may be important for anatomists, surgeons, podiatrists, and physicians. Following routine dissection, an accessory tendon of the TA muscle was found on both sides. Accessory tendons of the extensor hallucis longus and extensor hallucis brevis joined to form a common tendon on both sides. We believe that this unique case will help further the classification systems for the tendons of the TA and also be informative for clinical anatomists as well as physicians treating patients with pathology in this region.

Purpose: This study attempted to determine intra-rater reliability and inter-rater reliability for measurement of foot form using the FPI-6 (Foot Posture Index) in patients with hemiplegia caused by stroke. Methods: Twenty two stroke patients were recruited into the research and their foot posture was evaluated using the FPI. Two raters assessed 6 items sequentially in accordance with the FPI-6 manual. This procedure involved asking the subject to take several steps in-place, prior to settling into a comfortable stance position with double limb support. Subjects were instructed to stand still with their arms by their sides and look straight ahead. FPI-6 values ranged from -2 to +2 for each of the six criteria and from -12 to +12 for the total score, indicating a position for each foot either along the supinated (negative score) to pronated (more than +6) continuum of foot posture. Results: The results showed that intra-rater reliability and inter-rater reliability for a total FPI-6 score was high: 0.807-0.888. An almost perfect agreement between the two raters was identified in the foot's morphological classification (Somer's D=0.712; p<0.05). Intra-percentage agreement was high (88.6%). Conclusion: The FPI-6 is a quick, simple, and reliable clinical tool with demonstrated good to excellent intra-rater reliability and good inter-rater reliability when used in assessment of the stroke patient's foot.

This study identifies the foot side shapes of elderly men by classifying foot types according to 3D foot shapes and analyzing individual characteristics. The subjects were 284 elderly men over 60 years of age who lived in Gwangju and did not have foot related diseases. They were measured with a scanner (Nexcan$^{(R)}$ of K&I Technology) to obtain three dimensional feet shapes. Anthropometric measuring items consisted of 28 items estimated on the right foot of each subject. 3D scan data were analyzed by various statistical methods such as factor analysis, ANOVA and cluster analysis using the statistical program SPSS 19.0. A total of 7 factors were extracted through a factor analysis and these factors represent 77.56% of total variance. The 8 factors were: inside height and side gradient, ankle thickness, size from foot center to ankle, lateral malleolus height, forefoot height, instep and heel height and gradient. A total of 3 clusters (as foot type) were categorized using 7 factor scores by cluster analysis. Type 1 was classified as high forefoot and low midfoot compared to the length. Type 2 was classified as low forefoot and high midfoot, and type 3 was classified as low forefoot and low midfoot.

Purpose: To propose a new comprehensive classification system of intraarticular calcaneal fracture based on CT images. Materials and methods: Fourty intraarticular calcaneal fractures which were treated operatively were evaluated retrospectively. We classified fracture types according to severity of comminution on the posterior facet and calcaneocuboid joint by CT images. And we evaluated postoperative results of each fracture types in terms of the quality of fixation and reduction by the postoperative plain radiograghs. Results: By the classification of the posterior facet, 18 cases were P-I, 15 were P-II, and 7 were P-III. Among the P-I cases, 7 were P-IA, 9 were P-IL, 1 was P-IM and 2 were P-IT. According to the classification of calcaneocuboid joint, II cases were C-I, 18 were C-II and 11 were C-III. Qualities of fixation were excellent in 27 cases (67.5%), fair in 9(22.5%) and poor in 4(10%). Qualities of reduction were excellent 23 cases(57.5%), fair in 11(27.5%) and poor in 6(15%). Conclusion: Our new classification system based on the CT images could provide informations about the fracture configuration and severity of comminution around calcaneocuboid joint as well as the posterior facet. And the high grade fractures such as type P-III are need to be taken care of fixation of articular surfaces.

Purpose: The purpose of this study was to evaluate the questions pertaining to the foot and ankle on the Korean Orthopedic In-Training Examination (KOITE) between 2012 and 2016. Materials and Methods: Questions regarding the foot and ankle on KOITE during the five-year period (2012~2016) were analyzed. Number of foot and ankle questions, topics, taxonomic classification, imaging modalities, and cited references related to each question were analyzed. Results: The average number of foot and ankle questions was 35, accounting for 7.0% (35/500) of all KOITE questions. All questions were categorized into three topic areas: disease (51.4%, 18/35), trauma (31.4%, 11/35), and basics (17.1%, 6/35). Taxonomy 3 (decision-making type questions) was the most common (42.9%, 15/35). References that are commonly used for each question were Campbell's Operative Orthopedics (100%, 35/35) and the textbook of The Korean Orthopaedic Association (74.3%, 26/35). Conclusion: This analysis can be valuable to not only orthopaedic surgery residents to improve their knowledge of orthopedics, but also to instructors for optimizing their education programs.

Purpose: To evaluate the incidence and risk factors of ipsilateral reamputation after lower limb amputation in the patient with diabetic foot lesions. Materials and Methods: Between May 2005 and June 2009, 88 patients who underwent lower limb amputation were analyzed. Group 1 consisted of 73 patients who didn't have a ipsilateral reamputation after lower limb amputation and group 2 consisted of 15 patients who underwent reamputation. We compared several factors between two groups, such as age, gender, BMI, ABI, Wagner classification, wound culture, site of amputation, vascular surgery, the period of diabetes mellitus, chronic renal failure. Results: Fifteen (17%) of 88 patients had a ipsilateral limb reamputation and 13 patients (87%) of them underwent reamputation within 6 months. When we compared the two groups, average age was 59.3 (range, 48-74 years); 62.9(range, 44-78 years). Age was significantly associated with reamputation rate (p=0.02) and no reamputation after initial amputation above ankle joint was found. Other factors did not show statistically difference between both groups. Conclusion: There were no significant difference between diabetic limb amputation and reamputation group in our concerned risk factors except age and amputation level. There should be careful consideration when determine level of amputation in diabetic foot lesions especially in elder patients.

Purpose: The purpose of this study was to evaluate the effect of hyperbaric oxygen therapy(HBOT) and the resultant amputation rate in the treatment of diabetic foot ulcer. Material and methods: From 2000 Jan. to 2002 April, thirty two diabetic foot patients were admitted for treatment of foot ulcers and infection. Of the thirty two cases, thirteen patients received HBOT and nineteen did not. The results were analyzed by amputation rate and healing time. All were classified according to the Wagner classification. Results: Of the HBOT treated group, three(23%) patients underwent amputation: two below knee and one metatarsophalangeal disarticulations. Of the non-treated group, eleven(58%) patients underwent amputation, : four below knee and seven metatarsophalangeal disarticulations. The healing times, based on hospital days were average 16, 38, 43 days in the HBOT treated group and average 20, 50, 35 days in the non treated group respectively in Wagner grade II, III, IV. Conclusions: HBOT might be effective in decreasing amputation rate and hospital stay in diabetic patients with severe foot ulcers.
