  • Purpose: The purpose of our study is the comparison of radiological and clinical outcomes between modified distal chevron osteotomy and proximal metatarsal osteotomy for the patients who had moderate to severe hallux valgus deformity. Materials and Methods: In this retrospective study, we included 54 patients (65 feets) who underwent the operation of moderate to severe hallux valgus in our hospital from May 2007 to August 2010. Our study compares two groups. For Group 1, a modified distal chevron osteotmy and a distal soft tissue procedure were done and for Group 2, a proximal metatarsal osteotmy and a distal soft tissue procedure were done. The group 1 were 29 feets; the group 2 were 36 feets, and the average follow up was 9 months. Results: The radiological results show that the hallux valgus angle and the first-second intermetatarsal angle were significantly decreased in two groups. In each parameter, the correction of the hallux valgus angle was $19.1^{\circ}$ (Group 1) and $24.3^{\circ}$ (Group 2), the correction of the first-second intermetatarsal angle was $9.6^{\circ}$ (Group 1) and $10.3^{\circ}$ (Group 2). Shortening of the first metatarsal length was 0.87 mm (Group 1) and 0.77 mm (Group 2). There are no significant clinical results (American Orthopaedic Foot and Ankle Society score, AOFAS score) in two groups. Conclusion: It is thought that a modified distal chevron osteotomy and a distal soft tissue procedure are a considerable operative treatment of moderate to severe hallux valgus deformity because of the similar cilinical results, more simple operative techniques, and less complications than a proximal metatarsal osteotomy.

  • The purpose of this study is to analyze the immediate effects of five toed shoes on foot structure. Subjects consisted of 26 college-aged women with pes planus. X-ray analysis of student feet were performed both barefooted and with five toed shoes. Dependent variables were hallux valgus angle, calcaneal inclination angle, 1st metatarsal declination angle, and intermetartarsal angle. Independent t-test was used for statistical analysis along with SAS. Overall, there were statistically significant changes of test subject's dependent variables when wearing five toed shoes. Specifically, the hallux valgus angle decreased, the calcaneal inclination angle and 1st metatarsal inclination angle increased, and intermetatasal angles both increased and decreased, shifting towards normal range. In every case the dependent variables shifted towards a more normal range while subjects wore five toed shoes. This study only examined the immediate corrective effects of five toed shoes on foot structure, but long-term studies are needed to understand the prolonged effects of five toed shoes on foot structure.

  • Purpose: In this study, we tried to develop the technique of osteotomy for hallux valgus. The new modified technique of osteotomy was accomplished with even more greater stability, accurate correction of the deformity and more effective than 'chevron' osteotomy in terms of correction of the deformity. Materials and Methods: Between March 1998 and December 2001, 55 cases of new modified osteotomy for hallux valgus were performed for 39 patients, 16 of whom underwent operation of both feet. Operations were made for 34 women and 5 men whose average age was 46 years old (range, $20{\sim}71$ years). Average follow up period was three years (range, $2{\sim}5$ years), and during the follow up, the patients underwent physical examination and assessment with use of the American Orthpaedic Foot and Ankle Society's hallux-metatarso-phalangealinterphalangeal scale and standard foot radiographic measurements. Results: 37 patients (53 cases) out of 39 patients (55 cases) had no pain, good cosmesis, and all of the patients were satisfied with the results of the operation. Two had occasional mild discomfort. The average score according to the hallux-metatarso-phallangeal-interphalangeal scale was 93.2 points (range, $78{\sim}100$ points). The average preoperative intermetatarsal angle was $14.4^{\circ}$, which was decreased to $7.9^{\circ}$ after the osteotomy with an average correction of $6.5^{\circ}$ and The average preoperative hallux valgus angle was $34.1^{\circ}$, which was decreased to $11.1^{\circ}$ after the osteotomy with an average correction of $23^{\circ}$. This new modified technique would prevent the angulation or shortening at the osteotomy site and it was also even more stable at osteotomy site, and could do even more effective and accurate correction of the deformity than conventional Chevron osteotomy. Conclusion: New modified chevron osteotomy for the treatment of symptomatic hallux valgus was done in 55 cases, and the results were satisfactory in all cases. This method was more stable at the osteotomy site than conventional Chevron osteotomy and was also possible to do more accurate and more effective correction of the deformity. It was also easy to control the distal fragment of first metatarsal bone.

  • The purposes of this study were to investigate the relationship between anthropometric data of foot and other body sizes. to categorize the foot shape of elementary school boys and to find out determinant factors related the foot that enable us to deduce the foot shape and size for the design of more comfortable shoes. Subjects of this study were 249 elementary school boys of age ranged from 6 to 11 residing Seoul and lncheon area. Anthropometric sizes were measured with the direct measurement method using Martin scales and the indirect measurement method using digital photos. Pearson's correlation, factor analysis. cluster analysis. analysis of variance, post-hoc test, and cross tabs were performed for statistical analysis of the data by SPSS program. From the investigation on the relationship between foot-related items and body items, most items of foot measure were significantly related to body size items. However, angle of the foot did not related to other body sizes although other height items and mass items of the foot did have relationships with other body sizes. Results of ANOVA indicated there were significant differences in foot-related items except for items of foot angle and all body anthropometric items by subjects' age. This implicates big toe angle, little toe angle and foot ratio factors are required in sizing shoes besides foot length. On the basis of cluster analysis using factor scores. three different foot shapes were categorized. Type 1 was large and wide foot, Type 2 was small and narrow foot with large toe angle. and Type 3 was medium foot with no deformity on big toe. These three groups show significant differences in almost all measurement items. However, Rorher index and foot angle didn't show any significant differences among groups. This implicates the foot shape can be a determinant of shoe size.

  • The purpose are to assess the efficacy of a contact lateral-wedged insole with strapping on the femorotibial angle in patients with varus deformity osteoarthritis of the knee after treatment period. 25 outpatients with knee osteoarthritis (OA) were randomized to be treated with a contact lateral-wedge insole with strapping. Standing radiographs were used to analyze the femorotibial angle for each subject. The result of repeated two-way ANOVA's reveled that a contact lateral-wedged insole with strapping produced significantly differences in the femorotibial angle between groups after treatment period (P<0.05). and repeated one-way ANOVA's reveled that it produced significantly differences in the femorotibial angle between experimental groups after treatment period (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.

  • We report the case of 57-year-old woman diagnosed with Charcot-Marie-Tooth (CMT) disease and lumbar disk herniation (LDH). She had left leg weakness and foot numbness, foot deformity (muscle atrophy, high arch, and clawed toes). The lumbar spine MRI showed LDH at L4-5. Additionally, electrophysiology results were consistent with chronic peripheral motor-sensory polyneuropathy (axonopathy). In genetic testing, 17p11.2-p12 duplication/deletions characteristic of CMT disease were observed. We confirmed the patient's diagnosis as CMT disease and used conservative treatment.

  • It is important to train lower limb muscle strength using a tilting table to recover the lower extremity function of hemiplegia patients. It is known that the foot deformity and poor posture of hemiplegia patients can reduce the effectiveness of lower limb rehabilitation training. In this study, we developed a sensor system that can measure the foot pressure distribution of the patients for the load control of the lower extremity during lower limb rehabilitation training and it can be substituted for conventional high-cost technologies.

  • Purpose: To evaluate the radiological and clinical effects of early weightbearing after distal reverse oblique osteotomy of bunionette. Materials and Methods: Between 2009 and 2015, 52 patients who underwent surgical treatment at our hospital for bunionette deformity with a minimum follow up of one year were included in the study. Postoperatively, foot cast was applied and full weightbearing was permitted in 28 patients. And short leg splint was applied with only partial weightbearing using crutches allowed in 24 patients. Clinical scores were evaluated. Radiologically, the 4th~5th intermetatarsal angle (IMA), and 5th metatarsophalangeal angle (MPA) were analyzed preoperatively and at the final follow up visit. Results: The visual analogue scale and American Orthopaedic Foot and Ankle Society scores improved in the partial weightbearing group and full weightbearing group, but without significant differences. The average 4th~5th IMA and average 5th MPA correction also did not showed significant differences between the partial weightbearing group and full weightbearing group. Moreover, the full weightbearing group did not encourage non-union rate compared with the partial weightbearing group. Conclusion: Effective bone union may be achieved through early weightbearing, resulting in better clinical outcomes. It is considered that early weightbearing did not have any effect on the changes of IMA and bone union.
