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.

Purpose: The purpose of this study is to compare the treatment outcomes of distal chevron osteotomy with those of proximal metatarsal closing wedge osteotomy in patients with moderate severity hallux valgus. Materials and Methods: Forty-two patients (51 feet) who were underwent either distal chevron osteotomy (Group I, 22 patients, 27 feet) or proximal metatarsal closing wedge osteotomy (Group II, 20 patients, 24 feet) for the correction of moderate hallux valgus deformity were evaluated retrospectively. We assessed the radiographic results with several parameters including hallux valgus angle (HVA), intermetatarsal angle (IMA) and distal metatarsal articular angle (DMAA). And clinical results with modified AOFAS score at last follow-up. Results: There were no significant differences in IMA, HVA and DMAA between two groups preoperatively. We can achieve the good results with both procedures, but mean HVA and IMA of group II was significantly lower than those of group I. There was some loss of correction in group I at the last follow-up. There was no significant difference in clinical results according to modified AOFAS scoring between two groups at the last follow-up. Conclusion: The proximal metatarsal closing wedge osteotomy for the hallux valgus with moderate severity is better treatment option to achieve better radiographic correction and to prevent loss of correction or recurrence than distal chevron osteotomy.

Purpose: We are going to present a report from clinical and radiographic results of hallux valgus done only by soft-tissue procedure, when intermetatarsal joint is totally unfit under mild to moderate deformity. Materials and Methods: As a retrospective study, among all the patients who went under the surgery for hallux valgus, and of those who were possible to follow up,(excluding those whose intermetatarsal joint is fit) it was done over 28 cases (18 patients). the soft-tissue procedure was all done by Modified Mc Bride. Results: Hallux valgus angle and intermetatarsal angle each showed correction of $19.4^{\circ}$ and $5.2^{\circ}$, and from the final follow up, they were each decreased by $5.1^{\circ}$ and $1.5^{\circ}$. 21% (6case) were recurred, in one case, the intermetatarsal angle decreasing 120 and the other 5 case all decreased by $13^{\circ}$. Conclusion: when the intermetatarsal joint is unfit and there is no degenerative change, and, if the intermetatarsal angle is not large, moderate hallux valgus can show a good result, just by the distal soft-tissue procedure. a critical indication and a well through out preparation can reduce unneccessary surgeries.

Purpose: To study computerized measurements of angular parameters on 100% and 150% resized digital radiography of hallux valgus deformity Materials and Methods: 30 digital radiography of standing foot anteroposterior view of hallux valgus patients were included. Two observers(A, B) independently measured hallux valgus angle (HVA), 1-2 intermetatarsal angle (IMA), and distal metatarsal articular angle (DMAA) in two times on both 100%-size and 150% magnified images respectively, using computerized measurement software tools. The results were interpreted with the statistical software program, Statistical Analysis System, version 9.2. Results: In repeated measurements of each observer, measurements on 150% magnified image showed no differences of all three parameters and with 100%-size image, there were differences of HVA (observer A) and 1-2 IMA (observer B) (p>0.05). When testing interobserver reliability, both observers showed differences in measurement of HVA and DMAA (p<0.05), but no differences in measurement of 1-2 IMA in both images. Within the 95% confidence interval, limits of error of measurements between two observers on HVA, IMA and DMAA were $2.7^{\circ}$ $1.4^{\circ}$ and $5.0^{\circ}$ respectively in 100%-size images, and $2.6^{\circ}$, $1.6^{\circ}$ and $4.7^{\circ}$ respectively in 150% magnified images. Conclusion: In computerized measurements for angular parameters of hallux valgus with digital radiography, 150% magnified images showed intraobserver reliability. Both 100% and 150% magnified images failed to show interobserver reliability. Measurement of 1-2 IMA in both 100% and 150% images showed less interobserver error.

The osteochondroma is a cartilage-capped exostosis resulting from an error in the regulation of normal chondrocyte proliferation and maturation that leads to a normal bone growth. Although exostoses are benign lesions, they are often associated with characteristic progressive skeletal deformities and may cause clinical symptoms. Surgery can prevent progression and provide correction for certain deformities. We experienced a rare case of solitary osteochondroma in a 21-year-old male which caused the valgus deformity of the ankle.

Osteoarthritis has been considered a disease of the elderly because it is uncommon before the age of 40 years and is seen in approximately 80% of United States citizens older than 65 years. general population on kuri city in korea revealed that prevalence of knee osteoarthritis is 10.2%, increasing with age. High level of physical activity in men and age, post-menopause and obesity in women can be risk factor. Osteoarthritis is no evidence that a acquired process initiated much earlier in life through mechanical, metabolic, genetic, or other origins. A high tibial osteotomy alters static lower extremity alignment thereby decreasing medial compartment loading. As well, conservative treatment strategies, such as knee braces and valgus heel wedges, affect lover limb mechanics and attempt to reduce medial compartment loading. It was hypothesized that valgus heel wedges and modified orthoses would shift the center of pressure laterally on the foot during level walking, reducing the moment arm of the adduction moment in the frontal plane, thereby resulting in a decrease in the knee adduction moment. In the 1980s, the effect of wearing a laterally wedged insole on osteoarthritic patients with a varus deformity of the knee was firsted, and since then, kinematic and kinetic analyses concerning this condition have mainly focused on a static standing position. Since the early 1990s, the beneficial effect of wearing a laterally wedged insole to treat osteoarthritis of the knee has also been reported in dynamic conditions, but these studies did not answer the question of the kinematic and kinetic mechanisms that resulted in the reduced symptoms in patents with knee osteoarthritis. therefore, the effect of wearing laterally wedged insole has not been sufficiently studied.

Purpose: Proximal metatarsal chevron osteotomy for hallux valgus is followed by significant amount of postoperative pain. Periarticular multimodal drug local injection can be an option for pain control. This study was attempted to evaluate the efficacy of the morphine as multimodal drug and to confirm the effect of periarticular multimodal drug local injection on controlling early postoperative pain. Materials and Methods: Between March 2012 and June 2012, 22 patients received proximal metatarsal chevron osteotomy for the correction of hallux valgus deformity. 10 patients (Group A) received periarticular injection of the test solution made with morphine, ropivacaine, ephinephrine and ketorolac. 12 patients (Group B) received periarticular injection of the test solution without morphine. The visual analog scale (VAS) was checked at 2, 4, 6, 8 hours, 1 day and 2 days each after surgery. Results: The VAS score at postoperative 2 hours to 1 day between two groups showed no significant difference, but the VAS score at postoperative 2 days was significantly higher in Group A compared to the VAS score of group B. The amount of additional pain control (tramadol HCL) between two groups showed no significant difference for 3 days after surgery. Conclusion: Periarticular multimodal drug local injection was effective in reducing pain after hallux valgus surgery regardless of mixing with morphine.

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).
