The purpose of this study was to investigate the effect of donning of a hard insole in patients with hallux valgus. Fourteen subjects were selected from patient with foot pain at Lee Chang-Heon Foot Clinic from August 4, 2000 to September 15, 2000. The hallux valgus angle and the first-second intermetatarsal angle were radiographically measured before and after donning the hard insole. Based on these two kinds of angles, a mild hallux valgus deformity group was characterized by the hallux valgus angle of less than 20 degrees, and a moderate hallux valgus deformity group was characterized by the hallux valgus angle of 20 to 40 degrees. After three weeks with the hard insole donned, the foot angles of the patients with hallux valgus were measured again. The data were analyzed by Wilcoxon signed ranks test, and the following results were obtained: 1) After the trial, both mild hallux valgus deformity group and moderate hallux valgus deformity group demonstrated that the hallux valgus angles were significantly decreased. 2) After the trial, mild hallux valgus deformity group demonstrated that the first-second intermetatarsal angle was significantly decreased. 3) After the trial, moderate hallux valgus deformity group demonstrated that the first-second intermetatarsal angle was not significantly decreased. The above findings revealed that according to donning hard insole, the hallux valgus angles of mild and moderate hallux valgus deformity groups and the first-second intermetatarsal angle of mild hallux valgus deformity group were significantly decreased. The results of this study have some limitation for generalization due to the limited number of subjects. Further studies are needed to evaluate the effect of hard insole on hallux valgus with more precise laboratory equipments and measurements in patients with hallux valgus.

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.

Purpose: The aim of this study was to investigate the radiological characteristics of the osteoarthritis of the second metatarsophalangeal (MTP) and tarsometatarsal (TMT) joint. Materials and Methods: Between January 2002 and August 2010, 27 patients (33 feet) who had second metatarsal osteoarthritis (OA) were reviewed retrospectively. Group 1 was 14 patients (17 feet) with second MTP joint OA. Group 2 was 13 patients (16 feet) with second TMT joint OA. Group 3 was 24 patients (25 feet) had hallux valgus without second metatarsal (MT) OA as control. Weight bearing foot anteroposterior (AP) and lateral view were checked, and measured hallux valgus angle, metatarsus adductus angle (MAA), second MT functional length, first and second MT length by Hardy & Clapham method on AP view, angle of second MT with horizontal plane, calcaneal pitch, talo-first MT on lateral view. Results: On weight bearing foot AP view, second MT functional length of group 1, 2, 3 was 2.4 mm, -0.1 mm, 0.7 mm and MAA of group 1, 2, 3 was $17.7^{\circ}$, $17.7^{\circ}$, $14.5^{\circ}$. Second MT functional length of group 1 was longer than control group and it was statistically significant. MAA was significant different between group 1-3 and group 2-3. Angle of second MT with horizontal plane of group 2 was smaller than control group and it was statistically significant. Other radiographic parameters have no statistical significance. Conclusion: Group 1 has long functional length of second MT and group 2 has small angle of second MT with horizontal plane.

Purpose: The aim of the current study is to report on the clinical and radiographic results after calcaneo-stop procedure in Korean children with symptomatic flexible flatfoot. Materials and Methods: Twenty-two children suffering pain along the medial aspect of midfoot with flexible flatfoot whose symptoms did not improve with conservative measures and therefore underwent calcaneo-stop procedure were identified retrospectively. Clinically, American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot scale and visual analogue scale (VAS) were evaluated. Radiographically, standing anteroposterior and lateral radiographs of the foot and Saltzman's alignment views were taken and talonavicular coverage angle, lateral talo-first metatarsal angle, and hindfoot alignment angles were measured and analyzed. Results: Clinically, AOFAS ankle-hindfoot scale improved from $70.3{\pm}5.6$ to $97.3{\pm}2.5$ and VAS improved from $6.4{\pm}1.6$ to $0.2{\pm}0.4$. Radiographically, talonavicular coverage angle improved from $28.3^{\circ}{\pm}12.3^{\circ}$ to $10.9^{\circ}{\pm}8.1^{\circ}$, lateral talo-first metatarsal angle improved from $-19.3^{\circ}{\pm}9.0^{\circ}$ to $-2.4^{\circ}{\pm}8.1^{\circ}$, and hindfoot alignment angle improved from valgus $11.9^{\circ}{\pm}10.0^{\circ}$ to $3.5^{\circ}{\pm}4.3^{\circ}$ at minimum 2-year follow-up. No complications occurred postoperatively. Conclusion: Calcaneo-stop procedure is a simple and very effective procedure for management of pediatric symptomatic flexible flatfoot that does not respond to conservative treatment.

Background: We developed a modified proximal scarf osteotomy technique for moderate to severe hallux valgus in an attempt to obtain better correction of the deformity. In addition, we compared the clinical and radiographic results of this modified technique with those of the classic scarf osteotomy reported in other studies. Methods: Between December 2004 and July 2009, 44 cases of modified proximal scarf osteotomy was performed in 35 patients with moderate hallux valgus. The American Orthopedic Foot and Ankle Society (AOFAS) score, visual analogue scale (VAS) score, range of motion of the first metatarsophalangeal joint, and radiographic results were evaluated. Results: The mean hallux valgus angle and the mean first intermetatarsal angle improved from an average of $32.2^{\circ}$ and $14.3^{\circ}$, respectively, to an average of $12.5^{\circ}$ and $8.6^{\circ}$, respectively. The distal metatarsal articular angle improved from an average of $18.7^{\circ}$ to $12.4^{\circ}$. The preoperative mean AOFAS and VAS scores were 47 points and 7 points, respectively, which improved to 86 points and 1 point, respectively, at the final follow-up. Limited range of motion occurred in two cases postoperatively. The height of the first metatarsal-cuneiform joint, which was an average of 15.9 mm preoperatively, did not change. The first metatarsal-talus angle increased from an average of $4.1^{\circ}$ to $7.1^{\circ}$. Conclusions: The modified proximal scarf osteotomy for the treatment of moderate hallux valgus showed similar results with the classic scarf osteotomy with regard to changes in the first intermetatarsal angle and postoperative satisfaction. Therefore, we suggest the modified proximal scarf osteotomy be considered as well as other proximal osteotomy in the treatment of moderate to severe hallux valgus.

Purpose: To determine the radiographic changes in forefoot geometry with weight-bearing. Materials and Methods: The forefoot radiographs of 100 normal Korean adults, 50 male and 50 female volunteers, were evaluated both in nonweight-bearing and weight-bearing. The mean age was 27 years with range of 21-39 years. Those with normal feet were selected from volunteers having no history of foot problems or other musculoskeletal diseases. Results: The changes of measured angle between phalanges and metatarsals with weight-bearing were as follows; Hallux valgus angle was noted to increase in 20% of the feet, decrease in 59%, and remained unchange in 21%. Intermetatarsal angle $1{\sim}2$ was noted to increase in 76% of the feet, decrease in 3%, and remained unchange in 21%. Intermetatarsal angle $1{\sim}5$ was noted to increase in 95% and remained unchange in 5%. Shift in medial sesamoid on weight-bearing was also not consistent. Lateral shift was noted in 27%, no shift in 66%, medial shift in 7%. Conclusion: The generalized concept that the angles between bones and shift of medial sesamoid in the forefoot will change consistently with weightbearing was not found.

This study was initiated to investigate suitability of men's dress shoe sizes made for young men. Experiments were performed on 172 men for 19 to 29 years of age. Nine dimensions were measured from the subject's right foot and 11 dimensions were measrued from the outline of the foot. The data were analyzed for six different groups. The subjects were grouped by their dress shoe size or the ratio of the foot width to foot length. The result of the experiments lead to the following conclusions: 1. Foot length, metatarsal width and heel width were significantly different among the small, medium and large dress shoe size groups. 2. No significant differences in front foot angle and the inside metatarsal width were found among the above three groups. 3. The difference between wearing shoe size and the foot length was larger for the subjects with wide foot shape.
