Purpose: The purpose of this study is to evaluate the sequential changes of clinical and radiographic results after proximal chevron osteotomy in patients with moderate to severe hallux valgus. Materials and Methods: Between January 2008 and December 2009, 93 patients (117 feet) were treated with proximal chevron osteotomy and distal soft tissue procedure for symptomatic moderate to severe hallux valgus deformity. The mean age of patients was 51 years (range, 19 to 71) and the mean duration of follow-up was 27.5 months (range, 24 to 35). Clinical results were evaluated using visual analogue scale (VAS) and American Orthopaedic Foot and Ankle Society (AOFAS) score preoperatively, at 3, 6, and 12 months after surgery, and at the last follow-up. Radiographic parameters including hallux valgus angle, intermetatarsal angle, and sesamoid position were evaluated preoperatively, immediately postoperatively, at 6 weeks, at 3, 6, and 12 months after surgery, and at the last follow-up. Results: VAS and AOFAS score showed significant improvement until 12 months after surgery. Hallux valgus angle and sesamoid position stabilized at 12 months after surgery and intermetatarsal angle stabilized at 6 months after surgery. Conclusion: Clinical and radiographic results were stabilized beyond 12 months after proximal chevron osteotomy in patients with moderate to severe hallux valgus.

Hallux valgus is a deformity that causes pain in the first metatarsophalangeal joint. Surgical methods are quite diverse and a range of osteotomies are used at the proximal and distal part of the metatarsal bone and proximal phalange. Fixation methods, such as plate, screw, K-wire, and others have been used in various ways. The fixation device is often removed with various side effects due to the fixation devices. In the case of instruments that are absorbed in vivo, these procedures are not necessary to remove and there is an advantage of not performing the second operation. Three patients were treated, in which a proximal chevron osteotomy was used with a bioabsorbable screw (K-$MET^{TM}$; U&I Corporation).

Purpose: To treat hallux valgus in old age patients with chevron metatarsal osteotomy and to see the subsequent clinical and radiological outcomes. Materials and Methods: 23 cases of 18 hallux valgus patients of age 60 years or older who received proximal or distal corrective osteotomy from April 2007 to August 2009 and were followed up for at least 1 year were included in the study. The mean age at operation was 65 years (range, 60~81 years), and the mean follow-up period was 2 years and 6 months (range, 1 year~3 years 6 months). Clinical outcome was assessed with the American Orthopaedic Foot and Ankle Society (AOFAS) score, complications, satisfaction rate, as well as measurements and comparison of pre- and postoperative hallux valgus angles, the 1st~2nd intermetatarsal angle, and the position of hallucal medial sesamoid bone. Results: The AOFAS score was improved from preoperative average of 35.1 (range, 13-47) to average 85.1 at last follow-up (range, 75-100). Patients were satisfied about the operation in 21 cases (91.3%). Preoperative hallux valgus angle was $31.7^{\circ}$ on average (range, $19.1^{\circ}-48.9^{\circ}$), and $4.9^{\circ}$ on average at last follow-up (range, $0.3^{\circ}-21.2^{\circ}$). The 1st~2nd intermetatarsal angle was $14.4^{\circ}$on average (range, $8.7^{\circ}-25.7^{\circ}$) and $3.1^{\circ}$ on average at last follow-up (range, $0.6^{\circ}-7.5^{\circ}$). The hallucal medial sesamoid bone position was improved from preoperative average 3.5 (range, 3-4) to postoperative average 1.0 (range, 0-2). Conclusion: Proximal and distal metatarsal osteotomy treatment yielded good clinical and radiological outcomes in old age hallux valgus patients.

Purpose: The purpose of this study is to evaluate the characteristics of hallux valgus with severe hallux valgus angle (HVA) and moderate intermetatarsal angle (IMA) after proximal chevron osteotomy. Materials and Methods: Between January 2008 and December 2010, 41 patients (48 feet) were treated with proximal chevron osteotomy and distal soft tissue procedure for symptomatic severe hallux valgus deformity ($HVA{\geq}40^{\circ}$). Patients were divided into two groups, group M (IMA< $18^{\circ}$) and group S ($IMA{\geq}18^{\circ}$). Mean age of patients was 55.7 years (34~70 years) in group M and 60.0 years (44~78 years) in group S. Mean duration of follow-up was 20.4 months (12~41 months) in group M and 18.5 months (12~35 months) in group S. Radiographic parameters, including HVA, IMA, sesamoid position, metatarsus adductus angle (MAA), and distal metatarsal articular angle (DMAA), were compared between groups. Clinical results were assessed using American Orthopaedic Foot and Ankle Society (AOFAS) score and visual analogue scale (VAS). Recurrence rate at the last follow-up was compared between group M and group S. Results: Preoperative HVA and grade of sesamoid position did not differ between the groups. However, immediate postoperative HVA and grade of sesamoid position were significantly larger in group M. Preoperative MAA and DMAA were significantly larger in group M. No significant difference in AOFAS score and VAS was observed between the groups at the last follow-up. Ten of the 27 feet (37.0%) in group M and two of the 21 feet (9.5%) in group S showed hallux valgus recurrence at the last follow-up. Group M showed a significantly higher recurrence rate than group S. Conclusion: Recurrence rate for severe hallux valgus with moderate IMA is higher than that of severe hallux valgus with severe IMA.

Purpose: The purpose of this study was to figure out the appropriate and systemic insurance charge for the hallux valgus operations. Materials and Methods: 5 Hospitals for hallux valgus operations were analyzed how they have been charging the national health insurance corporation for their operation fees and how to use the estimated guide and authoritive interpretation through the guide book of health insurance medical treatment grant expense and the guide book of Health insurance medical treatment. Results: There are nothing for guiding principle of hallux valgus operations in both books but a guide of Mcbride operation which is approved 'JA-93-KA and JA-31' for operation fee. So majority of hospitals have charged operation fee depending on their own interpretations they like. According to the guide books, there was a authoritive interpretation that simultaneous operation of osteotomy and tendon transfer for cerebral palsy and flat foot can be eatimated as 'osteotomy+JA-93-NA'. Conclusion: Distal soft tissue procedure should be approved as 'JA-93-NAx100%+JA-31x50%' according to the the estimated guide and authoritive interpretation if transected adductor hllucis is transfered to first metatarsal head. So distal chevron osteotomy could be 'JA-30-1-RAx100%+JA-31x50%', proximal metatarsal osteotomy could be 'JA- 93-NAx100%+JA-31-50%+JA-30-1-RAx50%', first metatarsocuneiform joint arthrodesis could be 'JA-93-NAx100%+ JA-31x50%+JA-73-RAx50%'.

Purpose: This study evaluated the clinical and radiological results after reinforcement of the weakened medial joint capsule using Internal Brace (Arthrex) for treating severe hallux valgus. Materials and Methods: This study reviewed 56 cases of 50 patients that were followed-up postoperatively for at least 12 months, from September 2017 until August 2018. An extended distal chevron osteotomy combined with a distal soft-tissue release was performed by a single surgeon to treat severe hallux valgus. Internal Brace was applied in 12 cases (group A) who had weakened medial joint capsules, and capsulorrhaphy was performed in 44 cases (group B), and these two groups were compared postoperatively for the clinical and radiological results. The postoperative complications were also investigated. Results: No significant differences at 1-year follow-up on the Manchester-Oxford Foot Questionnaire and the patients' satisfaction scores were found between the two groups (p=0.905 and p=0.668, respectively). For the radiology, the changes of the values between before surgery and at 1-year follow-up according to the group showed no significant differences in the hallux valgus angle, intermetatarsal angle, and the hallux interphalangeal angle (p=0.986, p=0.516, p=0.754, respectively). Recurrence of hallux valgus was reported in two cases in group A, and in three cases in group B. Transfer metatarsalgia occurred in 4 cases in group B. Conclusion: Based on these results, we recommend the capsule reinforcing technique using Internal Brace as a successful operative option for treating a weakened medial capsule in patients with severe hallux valgus.

Purpose: This study aimed to report the current trends in the management of the hallux valgus (HV) deformity over the last few decades through a survey of the Korean Foot and Ankle Society (KFAS) members. Materials and Methods: A web-based questionnaire containing 34 questions was sent to all KFAS members in September 2021. The questions were mainly related to the preferred techniques and clinical experience in correction in patients with an HV deformity. Answers with a prevalence of ≥50% of respondents were considered a tendency. Results: One hundred and nine (19.8%) of the 550 members responded to the survey. The most common symptom for determining surgical treatment was bunion pain (68.8%), and different surgical techniques were selected according to the following radiological parameters: HV angle 30 to 40 degrees and intermetatarsal angle 15 to 20 degrees. The two procedures most preferred by the respondents were distal chevron osteotomy (55.0%), and proximal chevron osteotomy (21.1%). In an average of 71.6% of respondents, Arkin osteotomy was performed simultaneously during HV surgery. HV accompanied by an overriding deformity of the second toe was most often addressed with a combination of second metatarsal osteotomy and soft tissue rebalancing procedure (35.8%). After HV surgery, the recurrence rate of HV deformity was found to be 12.2% on average and the surgeons who had performed minimally invasive surgery (MIS) for HV comprised 34.9% of the total respondents. Conclusion: This study provides updated information on the current trends in the management of the HV deformity in Korea. Both consensus and variation in the approach to patients with HV were identified by this survey study. Although MIS for HV has increased, it appears the consensus for selecting this method has not yet been established.
