Hallux valgus is a complex deformity which contains static subluxation of the first metatarsophalangeal joint with lateral deviation of the great toe and medial deviation of the first metatarsal bone. Among the several parameters, radiographic indices are the important ones in the choice of the treatment method. Even though, the normal values of the western peoples are already estabilished, there was no standard values for Korean who has different genetics, and cultural background, till now. So, we tried to estimate the noraml values of the HVA (hallux valgus angle ), IMA ( Intermetatarsal angle) and DMAA (Distal Metatarsal Articular surface Angle) in a normal adult. Fifty normal adult (each 25 male and female) were chosen and took 100 cases of foot radiograph and radiologic indices of the hallux valgus were measured. Average age at the investigation was 34.5 years old. The average HVA is $13.3^{\circ}$, IMA is $8.5^{\circ}$ and DMAA is $34.6^{\circ}$.

Purpose: To investigate the relationship between radiographic parameters of the forefoot and plantar pressure in patients with hallux valgus. Materials and Methods: Plantar pressures of 21 patients with hallux valgus were examined with EMED-ST system. The data were compared with the parameters on the simple weightbearing dorsoplantar radiographs of the feet. The radiographic parameters that were measured were hallux valgus angle, 1-2 intermetatarsal angle, relative lengths of the metatarsals which were measured with the methods described by Maestro et al. and Okuda et al. Results: Statistically significant correlation was found between peak pressures under 2, 3 metatarsal heads and the relative lengths of 2, 3 metatarsals which were measured with the method described by Maestro et al. However they could explain only 13% of the pressures under the 2, 3 metatarsal heads by multivariate analysis. Conclusion: These results suggest that we cannot predict the plantar pressures under the foot with the parameters on the simple weightbearing dorsoplantar radiographs of the feet.

Hallux valgus is a hereditary deformity whose natural history is influenced by intrinsic and extrinsic factors. The deformity is infrequently noticed in newborns and infants because of its trivial nature that does not draw attention. Because in childhood and adolescence this deformity usually does not lead to functional disability, it is seldom treated actively. Opinions differ concerning the causal relationship of these deformities and appropriate treatment. It is clear, however, that the deviated great toe continues to deform, and leads to a chain of anatomical and functional changes. Thus, the advantages of the immediate treatment is obvious, especially in infancy, when the foot is supple. We are reporting one case of congenital hallux valgus with brief review of literature.

Recurrence is a common complication following hallux valgus surgery. The postoperative recurrence rates have been reported to be between 2.7% and 16%. Reoperation is considered only for the recurrent deformities with intractable pain. The success of reoperation depends on identifying and addressing the cause of the recurrence appropriately. The surgical principle of reoperation for a recurrent hallux valgus is similar to that of the primary surgery, but arthrodesis and proximal metatarsal osteotomies with greater correcting power are adopted more frequently.

The aim of this study was to observe the effects of kinesiotaping and joint mobilization on the metatarsophalangeal joint angle and pain in hallux valgus patients Twenty-one female hallux valgus patients in their 20s were divided into two groups, a Kinesiotaping group (KT, n=10) and another group with the addition of joint mobilization (KTJM, n=11). After undergoing 6 weeks of intervention, the change in the metatarsophalangeal joint and pain were measured. Metatarsophalangeal joint angle was significantly increased both the KT and the KTMJ group after intervention. In the change of pain, both the KT and KTJM groups on an individual basis also experienced a significant decrease in pain, though comparison between the two groups failed to represent a significant difference. These findings suggest that Kinesiotatping and joint mobilization increased the joint angle and reduced pain.

Hallux valgus with metatarsus adductus is difficult to treat and has a higher risk of recurrence after correction. Some treatments for hallux valgus with metatarsus adductus have been reported, but these are extensive procedures with a risk of complications associated with the shortening and malposition of the lesser metatarsals. The technique described here is easier to perform and has several advantages over the previously reported techniques.

Recurrent deformity following hallux valgus surgery can be technically challenging to treat. In cases of revision surgery, a surgical technique with greater corrective power is often chosen compared to the primary surgery. Therefore, minimally invasive surgery is not commonly performed. On the other hand, minimally invasive surgery minimizes soft tissue damage and allows for greater correction of deformity compared to traditional open approaches. This paper reports four cases of recurrent hallux valgus treated with a minimally invasive distal transverse metatarsal osteotomy - Akin osteotomy (MITA), resulting in significant improvements in the clinical and radiographic outcomes.

Purpose: "Hallux valgus" is a common disease encountered in clinical practice and is accompanied by foot deformities. Conservative treatment is commonly used in the early stages of hallux valgus. On the other hand, surgical treatment often becomes necessary as the deformity progresses. Surgical treatments involve various osteotomy methods or joint fusion procedures combined with soft tissue release, and outcomes from these surgical treatments are generally favorable. This study compared two soft tissue release techniques in the hallux region. Materials and Methods: This study conducted a retrospective cohort study on 48 participants who underwent surgical treatment for hallux valgus at a single institution from March 1, 2018, to March 31, 2023. A scarf osteotomy was performed in all cases, and the "Modified Mcbride procedure" or "Trans-articular approach" was done for soft tissue release. Hallux valgus angle (HVA), intermetatarsal angle (IMA), and the degree of subluxation of the lateral sesamoid were measured through simple foot radiographs taken before surgery and one year after surgery. Results: In the Modified Mcbride procedure group, HVA, IMA, and the sesamoid position grade decreased from 34.94° to 9.98°, 15.64° to 5.44°, and 2.47 to 0.44, respectively. In the trans-articular approach group, HVA, IMA, and the sesamoid position grade decreased from 33.42° to 7.34°, 15.06° to 6.03°, and 2.17 to 0.58, respectively. There was no significant difference in these changes between the preoperative and one-year postoperative measurements for both techniques (p-value>0.05). Conclusion: A radiological assessment of soft tissue release through the Modified Mcbride procedure and trans-articular approach in hallux valgus did not show significant differences. Therefore, both surgical techniques can be considered in the distal soft tissue release for a hallux valgus correction.

Purpose: We compared the result of a proximal metatarsal closed wedge osteotomy and soft tissue procedure with a modified chevron osteotomy and soft tissue procedure in the treatment of hallux valgus. Materials and Methods: Between March 1999 and February 2003, we performed proximal metatarsal closed wedge osteotomy and soft tissue procedure on 17 feet (12 patients), and modified chevron osteotomy and soft tissue procedure on 12 feet (9 patients). Results: According to Mayo clinic forefoot scoring system (FFSS), group 1, with proximal metatarsal closed wedge osteotomy, shows 67.2 points postoperatively and group 2, with modified chevron osteotomy, shows 68.5 points postoperatively. In group 1, the average correction of hallux valgus angle and intermetatarsal angle was 20.8 degrees and 4.8 degrees, respectively. In group 2, the average correction of hallux valgus angle and intermetatarsal angle was 19.9 degrees and 4.7 degrees, respectively. The average shortening was 3.15 mm in group 1 and 1.38 mm in group 2. Conclusion: We obtained relatively good clinical and radiographic result in this study. The effect on shortening of the first metatarsal was greater in the proximal metatarsal closed wedge osteotomy than modified chevron osteotomy, but the metatarsal shortening did not related with metatarsalgia. So, both techniques seems optimal surgical treatment for hallux valgus deformity.

Purpose: In this study, we introduced a newly developed technique of operation for hallux valgus. We used a single dorsal incision to correct major components of Bunion in stead of two or three incisions, which had been used by most of surgeons for long time. Materials and Methods: Between 2003 and 2005, 27 feet with hallux valgus deformity were operated through single dorsal incision. 10 out of 17 patients underwent operation on both feet, 5 patient underwent operation on left feet, remaining 2 underwent operation on right. There were 16 women and 1 man. Average age of patients was 45 (range, 21-59). Post operatively all feet were evaluated by physical examination, Maryland Foot score profile, radiographic measurements and complication. Results: Maryland foot score profile increased from preoperative 67/100 to postoperative 95/100. Most patients satisfied pain relieve and cosmesis. Average preoperative intermetatarsal angle was 15 degrees, which were decreased to 9 degrees after operation and average preoperative hallux valgus angle was 32 degrees, which were decreased to 12 degrees after operation. Conclusion: According to our experience, the single dorsal incision technic for correction of moderate to severe hallux valgus deformities was rather safe and easily performed without noticeable complication with almost same results as multiple incisions technics. We highly recommend this technic to be tried by foot surgeons without hesitation.
