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: Hallux valgus (HV) is a common foot deformity that causes pain in the first metatarsophalangeal joint. Distal metatarsal osteotomies are commonly performed as a treatment. This retrospective study compared the clinical and radiological results of bioabsorbable magnesium (Mg) versus titanium (Ti) screw fixation for modified distal chevron osteotomy in HV. Materials and Methods: Forty-nine patients, who underwent modified distal chevron osteotomy for HV in 2018 and 2019, were reviewed retrospectively. Bioabsorbable Mg screw fixation was applied in 20 patients (22 feet), and a traditional Ti compression screw was applied in 29 patients (40 feet). The patients were followed up for at least six months. The clinical results were evaluated using the American Orthopaedic Foot and Ankle Society hallux metatarsophalangeal-interphalangeal (AOFAS-MTP-IP) scale and a visual analogue scale (VAS). The hallux valgus angle (HVA), intermetatarsal angle (IMA), and distal metatarsal articular angle (DMAA) were measured before, after surgery, and at the six months follow-up. Results: The AOFAS-MTP-IP scale and VAS points were improved in both groups, with no significant difference between them. At the six-month follow-up, HVA, IMA, and DMAA were similar. Bone union was confirmed in both groups, and there were no significant major complications in both groups. Four people in the Ti screw group underwent implant removal surgery. Conclusion: Bioabsorbable Mg screws showed comparable clinical, radiologic results to Ti standard screws six months after distal modified chevron osteotomy. These screws are an alternative fixation material that can be used safely and avoid the need for implant removal operations.

Purpose: Previous studies reported changes in the first metatarsophalangeal (MTP) joint angle in relation with and without weight bearing, but it is unclear whether sesamoid bone of the great toe changes in weight bearing conditions particularly in subjects with hallux valgus (HV). To investigate how weight bearing conditions can affect the position of the medial sesamoid bone (MSB), first MTP joint angle, and second intermetatarsal angle (IMA) in the recruited subjects. Methods: Subjects were recruited 24 with HV and 21 without HV in study. X-rays were taken in the weight bearing and non-weight bearing conditions. The distance of the MSB, first MTP joint angle, and second IMA were measured from the radiographs. Data were analyzed by paired and Independent t-test. The statistical significance level was p<0.05. Results: In both groups, the first MTP joint angles and the distance of the MSB were significantly smaller, while the second IMA was significantly greater in the weight bearing condition. The difference in the distance of the MSB between the two postures was significantly greater in the group with HV. Conclusion: Weight bearing can affect the first MTP joint angle, second IMA, and position of the MSB; the change in the position of the MSB in weight bearing was greater in the group with hallux valgus. The difference in these variables between weight bearing and non-weight bearing conditions may be considered when measuring HV.

Purpose: This study aimed to compare the impact of proprioceptive neuromuscular facilitation leg patterns emphasizing hallux abduction (PNF-LPHA) on the intrinsic foot muscles of participants with hallux valgus (HV) using the toe-spread-out exercise (TSO). Methods: The present study recruited 12 individuals with HV. All the participants voluntarily agreed to participate in the study after hearing explanations of its purpose and process. All participants performed the TSO, PNF-LPHA 1, and PNF-LPHA 2. The participants' abductor hallucis (AbH), adductor hallucis (AdH), extensor hallucis longus (EHL), and flexor hallucis brevis (FHB) activity was measured, and the ratio of AbH:AdH was measured during the three interventions using electromyography. Additionally, the participants' AbH thickness was measured by ultrasonography. An intraclass correlation coefficient (ICC) was used to verify the intra-rater reliability of ultrasonography at rest and during contraction. Results: The intra-rater reliability was excellent at rest and during contraction ($ICC_{3,1}=0.90$ and $ICC_{3,1}=0.83$, respectively). There were no statistically significant differences in the activity of the AbH, the ratio of AbH: AdH, and the thickness of AbH between the TSO and PNF-LPHA2 groups. Additionally, EHL activity was significantly higher in the PNF-LPHA2 group than in the TSOgroup. Conclusion: PNF-LPHA 2 can be recommended as a method to optimize AbH and EHL activity, the ratio of AbH:AdH, and the thickness of AbH in individuals with HV.

Avascular necrosis of the first metatarsal head is uncommon. It is most often seen following a distal metatarsal osteotomy for hallux valgus. Although many cases may be subclinical, it is a powerful cause of failure of bunion surgery. Avascular necrosis of the first metatarsal head results in a series of events that begins with phases of avascularity; revascularization, with or without collapse; and reossification. Collapse may result in degenerative change of the metatarsophalangeal joint. We have recently experienced a case of avascular necrosis of the first metatarsal head.

Hallux valgus, or a 'bunion', is a deformity characterized by lateral deviation of the big toe. Surgery is indicated when conservative treatments have failed to result in improvement of symptoms. Operative techniques include simple bunionectomy, distal soft tissue procedure, phalangeal osteotomy, metatarsal osteotomy (distal, shaft, or proximal), arthrodesis (metatarsophalangeal or tarsometatarsal), or resection arthroplasty. Good results are expected when the selection of operative technique is based on the correct treatment principle.

Occurrence of pseudoaneurysm in the foot and ankle is rare, and is usually caused by traumatic injury or by iatrogenic intervention. Iatrogenic pseudoaneurysms in the foot and ankle have been observed after rearfoot and ankle fusions, ankle arthroscopy, endoscopic and open plantar fasciotomy, tibial osteotomy with limb lengthening, midfoot amputation, and Lapidus procedure. We report on a patient who developed a pseudoaneurysm of the dorsal metatarsal artery following correction of hallux valgus. The patient underwent proximal chevron osteotomy and Akin phalangeal osteotomy. The feeding artery was ligated and the pseudoaneurysm was excised.

23 hallux valgus patients were evaluated with clinical examinations and plantar pressure distribution measurements. A masking method for detailed plantar pressure distribution analyses was suggested. With higher grade of hallux valgus, pressure, contact length & area, and impulse on metartasus were significantly increased. Localized pressure concentration is very important in foot diseases and appropriate plantar pressure distributions should be considered on any shoe design.

Small osteophytes are frequently encountered in the foot and ankle, and not to be confused with true osteochondromas, which are relatively uncommon in this region. Osteochondromas are the most common benign osseous neoplasm, occurs in the metaphysis of the long bone. It is rarely found in bones of the foot. Treatment of the osteochondroma is usually conservative, unless symptoms usually pain, are progressive rapid growth, and malignant transformation is suspected. We experienced a rare case of hallux rigidus with osteochondroma of the hallucal proximal phalanx which cause pain and corn of the plantar.
