In order to study the foot deformity hallux valgus, the rate of which is currently increasing, 235 patients who were diagnosed with hallux valgus and treated in an orthopedic hospital in Seoul had their feet calibrated before and after surgery using 3d radio-scans. Data from 209 cases was analyzed and scored numerically. We scored 10 items for length, 4 for width, 3 for angle, and 2 for height, for a total of 20 items. Each individual's feet showed great variation in most of the items and significant differences after surgery, especially in regards to length and height, which increased after surgery. Angle, width, and length of the distal parts of the toes decreased after surgery. Based on the results of our analysis, we conclude that surgery brings about significant changes in structure and measurement of feet. This research confirmed that there is significant variation in foot form and individual differences based on lesion size and location and, thus, it is difficult for hallux valgus patients to find ready-made shoes that fit them properly. Foot changes before and after operation for hallux valgus were analyzed and the results quantified; our results should be considered during product design by shoe companies whose target is adult women.

The purpose of this study was to evaluate the effect of joint mobilization and manual stretching exercises in patients with hallux valgus. Twenty-three participants were divided into two groups; joint mobilization (n=11) and manual stretching exercises (n=12). The subjects participated in the experiment for 15minutes, three times a week, four weeks. The joint mobilization (Grade III, Maitland) was performed to experimental group for a minute and then rested for 10 seconds for each set. The manual stretching was performed to control group with three exercise session (preparatory and finishing exercises, agonist contraction exercises, agonist contraction and hold-relax exercises). In the results of the study, intragroup comparison of the deformity angles (DA) was shown to decrease from $15.18^{\circ}$ to $13.09^{\circ}$ in the joint mobilization group (p<.05) and from $19.00^{\circ}$ to $16.83^{\circ}$ in the stretching exercises group (p<.05). However, left static foot pressure (LSFP), right static foot pressure (RSFP), left dynamic foot pressure (LDFP) and right dynamic foot pressure (RDFP) did not significantly increase or decrease after the experiment. Intergroup differences also were not statistically significant in all variables (p>.05). The current study suggests that JM and MSE are effective in decreasing the DA in patients with hallux valgus.

Purpose: We wanted to evaluate the relating factors for deformities of the foot after tibial fracture and the outcome of respective surgical treatment. Materials and Methods: We studied thirty-two patients (thirty-five feet) who had foot deformities after tibia fracture. The age, gender, shape, location, concurrent soft tissue injury and operative treatment of tibial fracture were analysed and outcome of the surgical treatment was investigated. Results: Deformities of the foot mostly occurred in open fractures of Gustilo type 3 or closed fracture with severe soft tissue injury. Variable surgical treatments such as simple release, lengthening, Z-plasty and osteotomy were performed. The AOFAS ankle-hind foot scale was improved from average of 37.3 points preoperatively to an average of 77.2 points at the last follow up. The Maryland foot score was from 42.9 to 90.2 and AOFAS Lesser Toe Metatarso-phalangeal interphalangeal scale was from 42.9 to 90.5. Radiological correction was also improved from 21.9 degrees to 7.9 degrees (Meary angle), from 112.2 to 138.5 (Hibb's angle) and from 33.8 to 25.9 (Calcaneal pitch). Conclusion: We proposed that great care should be taken of treatment for the tibial fracture and early detection and proper management of the foot deformities are crucial.

Purpose: A flatfoot that fails to form a longitudinal foot arch is a common lower limb deformity in children. This study evaluated the structural and functional effects of the insole for pediatric flexible flat foot (PFFF). Materials and Methods: Twenty-nine PFFF patients (20 boys and 9 girls, 58 feet) with bilateral symptomatic flatfoot deformities between February 2017 and May 2019 were included in this study. Sixteen patients (32 cases, study group) were treated with a pressured based 3-dimensional printing insole, and 13 patients (26 cases, control group) were followed up regularly without any treatment. Flatfoot was diagnosed by a lateral talo-first metatarsal angle of more than 4° in convex downward and talocalcaneal angles of more than 30° and a calcaneal pitch of less than 20°. The foot pressures, including the midfoot pressure, total foot pressure, and the ratio of the midfoot pressure to the total foot pressure, were evaluated by pedobarography. The clinical scores were assessed using the visual analogue scale (VAS), American Orthopaedic Foot and Ankle Society (AOFAS), and Pediatrics Outcomes Data Collection Instrument (PODCI) scores. Results: The mean age of the study group was 9.16 years, and the mean age of the control group was 7.73 years. The mean follow-up period was 16 months. The change in the lateral talocalcaneal angle was -4.664°±1.239° in the study group and -0.484°±1.513° in the control group. A significant difference in the amount of change of the lateral talocalcaneal angle was observed between the two groups (p=0.034). The midfoot pressures were similar in the two groups. Conclusion: Pressure based customized 3-dimensional printing insole in PFFF may have some effect on the hindfoot bony alignment, but it does not affect the changes in midfoot pressure.

Purpose: The aim of this study was to evaluate the radiological and clinical outcomes of scarf osteotomy for hallux valgus (HV) deformity in elderly patient with osteoporosis. Materials and Methods: A total of 58 elderly patients (mean age, 72.6 years) underwent scarf osteotomy for HV deformity between 2008 and 2015. The mean follow-up period was 24.4 months. Of the 58 patients, 42 were diagnosed with osteoporosis and 16 were diagnosed as normal. The radiological and clinical outcomes were assessed preoperatively, postoperatively, and at final follow-up, including HV angle, intermetatarsal (IM) angle, American Orthopaedic Foot and Ankle Society (AOFAS) score, patient satisfaction, visual analogue scale (VAS), and complication. Results: There was no significant difference in HV angle and IM angle between the osteoporosis group and normal bone mineral densitometry group at all time points, preoperative, postoperative, and final follow-up. Moreover, there was no statistically significant difference between the two groups with respect to the AOFAS score and VAS evaluations. In the osteoporosis group, the mean HV angle improved from $36.7^{\circ}$ preoperatively to $11.3^{\circ}$ at the time of final follow-up, and the mean IM angle improved from $13.2^{\circ}$ to $5.7^{\circ}$. The mean AOFAS score improved from 52.6 preoperatively to 89.1 at the time of final follow-up. With respect to satisfaction, 83.4% of patients were very satisfied or satisfied. There were no serious complications, and all cases showed complete union at the osteotomy site. Conclusion: We believed that scarf osteotomy is a safe, effective procedure for the correction of elderly patients with osteoporosis.

Purpose: The purpose of this study was to evaluate the clinical and radiographic results of the parallel-shaped modified Scarf osteotomy which is performed the Scarf osteotomy parallel to the shaft of the 1st metatarsal bone for hallux valgus deformities. Materials and Methods: We retrospectively reviewed 43 patients who had been treated by the parallel-shaped modified Scarf osteotomy for hallux valgus deformities between January 2006 and March 2011. We evaluated the results after this Scarf osteotomy with respect American Orthopaedic Foot & Ankle Society (AOFAS) scores, radiologic results by comparing intermetatarsal angle between 1stand 2nd metatarsal bones and hallux valgus angle. Results: We checked out the pre-operational and post-operational radiologic evaluation of intermetatarsal angle and hallux valgus angle between 1st and 2nd metatarsal bones. The mean AOFAS scores improved from 63.5 to 88.5. At final follow up, The hallux valgus angle improved from $31.4^{\circ}$ (16-52) to $9.0^{\circ}$ (3-13) and the intermetatarsal angle improved from $18.6^{\circ}$ (12-30) to $9.3^{\circ}$ (6-12) postoperatively. There was no case of major complications included recurrence of valgus deformity, correction or fixation failure and stress fractures. Conclusion: Our results suggest the our parallel-shaped modified Scarf osteotomy produces improved AOFAS scores, and effective correction of hallux valgus deformities. Our Scarf technique of osteotomy which is performed in parallel to the metatarsal bone minimizes the need for skill while more reliable and obtaining good correction and avoids associated complications.

Purpose: Tibiotalocalcaneal arthrodesis has been used as a treatment option for severe deformity including Charcot arthropathy, avascular necrosis of the talus, and severe osteoarthritis of the ankle and subtalar joint. The purpose of this study was to evaluate the result of the surgical outcome of tibiotalocalcaneal arthrodesis using a retrograde intramedullary nail. Materials and Methods: Tibiotalocalcaneal arthrodesis using a retrograde intramedullary nail was performed by one surgeon in 36 cases. Clinical and radiological finding was evaluated using assessment of fusion time, 5th metatarsal-tibial angle, possibility of postoperative complication, visual analogue scale for pain and American Orthopaedic Foot and Ankle Society (AOFAS) score. Results: Union was achieved in 33 cases at an average of 23 weeks (11~29 weeks). There were 3 cases of nonunion and 1 case of reoperation. Nail-tibial angle tended to be larger in nonunion cases. AOFAS score showed significantly poor outcome at malalignment (${\geq}5^{\circ}$), negative value of 5th metatarsal-tibial angle. Conclusion: Tibiotalocalcaneal arthrodesis using a retrograde intramedullary nail is considered a useful treatment option for severe destruction and deformity involving ankle and subtalar joint.

Purpose: We evaluated the result of operative treatment of the hallux valgus in male patients. Materails and Methods: Total 11 cases (10 patients) of the hallux valgus deformity that treated with operation were evaluated. Following Mann's radiological classification system, there was 1 cases of mild, 8 cases of moderate, and 2 cases of severe. Preoperative, postoperative, postoperative 3 months and postoperative 6 months follow up standing radiographs were used as radiologic evaluation. And we evaluated radiological outcomes by hallux valgus angle (HVA), first-second intermetatarsal angle (IMA), distal metatarsal articular angle (DMAA), proximal phalangeal articular angle (PPAA) and clinical outcomes by hallux-metatarsophalangeal scale of American Orthopaedic Foot and Ankle Society (AOFAS) score. Result: Radiologically, the mean preoperative HVA $37^{\circ}$ and IMA $13.7^{\circ}$ were improved postoperatively as HVA $11.9^{\circ}$ and IMA $4.7^{\circ}$, and the mean preoperative DMMA $29.4^{\circ}$ and PPAA $8.6$ were improved postoperatively DMMA $13.9^{\circ}$ and PPAA $7^{\circ}$. But, postoperative 6 months follow up HVA, IMA, DMMA and PPAA was increased at $14.2^{\circ}$, $6.3^{\circ}$, $16.1^{\circ}$ and $8.3^{\circ}$. Average AOFAS score were improved from 61.2 points to 75.2 points. Conclusion: In our study, operative treatment of hallux valgus in male patients with proximal metatarsal osteotomy and distal soft tissue procedure showed good results but it was necessary to pay attention to increase aspect of follow up radiologic measurements.

Purpose: To determine the clinical and radiographic results of arthroereisis using the $Kalix^{(R)}$ implant (Newdeal, Lyon, France) for the treatment of flexible flatfoot deformity. Materials and Methods: From February 2005 to February 2007, we performed the subtalar arthroereisis on 8 patients (9 feet) of symptomatic flexible flat feet after more than 6 months of conservative treatment. Average age was 14.5 years ($11{\sim}29$ years) old. We checked the functional status with AOFAS functional score pre-operatively and at final follow-up. Radiologically, we took weight bearing anterior to posterior and lateral view of the feet, and measured the talo-first metatarsal angle, calcaneal pitch angle in pre-operatively and at final follow-up. Results: Mean follow up period was 34.4 months. Average AOFAS score improved from preoperatively 65.6 to postoperatively 94.8. Average lateral talo-first metatarsal angle reduced from $12.8^{\circ}$ preoperatively to $1.6^{\circ}$ at final follow-up. Average anterior to posterior talo-first metatarsal angle was reduced from $15.1^{\circ}$ preoperatively to $8.3^{\circ}$ at final follow-up. Average calcaneal pitch angle was increased from $9.5^{\circ}$ preoperatively to $12.0^{\circ}$ at final follow-up. Conclusions: Subtalar arthroereisis with Kalix$K^{(R)}$ implant can be considered to be one of treatment options symptomatic flatfoot deformity patients.
