Purpose: The purpose of this study was to evaluate the radiological and clinical results of modified scarf osteotomy for hallux valgus with lesser metatarsalgia. Materials and Methods: Total 19 patients (24 feet) were reviewed by medical records and radiographs. All patients were female and the mean age at the time of operation was 46.4 years. The mean follow-up time was 14.8 months. We modified original scarf osteotomy by adding the procedure of closing wedge osteotomy at the medial side of distal fragment for achieving of the supination of the first metatarsal head. Additionally, Akin osteotomy of the first proximal phalanx was done in 16 patients (20 feet) and no lesser metatarsal operation was done. First-second intermetatarsal, hallux valgus and distal metatarsal articular angles were analyzed radiologically before and after the operation. And 3-dimensional CT was used to evaluate the supination of the first metatarsal head. Clinical results were assessed by American Orthopaedic Foot and Ankle Society (AOFAS) score and persistence of lesser metatarsalgia. Results: First-second intermetatarsal and hallux valgus angles were reduced from the mean pre-operative values of $14.2^{\circ}$ and $32.5^{\circ}$ to $8^{\circ}$ and $12.5^{\circ}$, respectively, 12 months after the operation. And the supination of the first metatarsal head was confirmed by 3-dimensional CT. The mean AOFAS score improved from 41.4 points pre-operatively to 87.2 points at follow-up. Lesser metatarsalgia still remained in 2 patients (2 feet). Conclusion: Modified scarf osteotomy would be an effective surgical procedure, especially, for achieving downward displacement and supination of the first metatarsal head in hallux valgus with lesser metatarsalgia.

Purpose: The authors intended to analyze the operative results of mild to moderate hallux valgus treated with distal chevron metatarsal osteotomy. Materials and Methods: Twenty six feet of twenty three patients were followed for more than 1 year after the distal chevron metatarsal osteotomy. Biplanar osteotomy with wedge resection was done when the distal metatarsal articular angle (DMAA) was increased. The mean age was 39 years, and the mean follow up period was 27 months. Clinically preoperative and postoperative AOFAS hallux MP-IP scale and satisfaction after the surgery were analyzed. Radiologically hallux valgus angle, the 1st intermetatarsal angle, DMAA and sesamoid position before and after the operation were analyzed. Results: Distal chevron osteotomy was done in 15 cases and biplanar osteotomy was done in 11 cases. Clinically AOFAS scale was increased from 65.3 points preoperatively to 92.2 points postoperatively. Two patients were not satisfied with the results. Radiologically hallux valgus angle was decreased from $21.9^{\circ}$ preoperatively to $8.5^{\circ}$ postoperatively. The first intermetatarsal angle was decreased from $11.8^{\circ}$ preoperatively to $6.7^{\circ}$ postoperatively. DMAA was decreased from $11.8^{\circ}$ preoperatively to $5.5^{\circ}$ postoperatively. There was one case of minor wound infection. Conclusion: Distal chevron metatarsal osteotomy appears to be safe and satisfactory procedure for mild to moderate hallux valgus.

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.

Background In postaxial polysyndactyly of the foot, the choice of which toe to excise is controversial. It is often treated by resection of the fifth toe to save the lateral neurovascular bundles of the sixth toe. However, the sixth toe is often short and laterally deviated, which may require wedge osteotomy, potentially shortening the phalanx and compromising circulation. This study outlines an individualized method to spare the length and axis of the fifth toe in polysyndactyly with a short and deviated sixth toe. Methods We retrospectively analyzed 38 patients who underwent surgery between 2006 and 2019. The fifth toe was spared in 18 cases, and the sixth toe in 20 cases. The ratios of the forefoot width, angle difference, and toe length were compared between the affected and unaffected sides postoperatively. Complications and subjective judgments on cosmetic results were recorded and compared. Results No significant between-group differences were observed for sex, age at surgery, or the follow-up period. The forefoot width ratio did not significantly differ between the groups. However, the angle difference and toe length ratios showed significantly better results in the fifth toe-spared group than in the sixth toe-spared group (P<0.05 and P<0.01, respectively). There were no cases of impaired circulation, and subjective evaluations revealed satisfactory results in the fifth toe-spared group. Conclusions In cases with short and deviated sixth toes, sparing the fifth toe is an effective method of cosmetic treatment. The surgical results were satisfactory, with an improved appearance and no residual deformities.

Ankle arthrodesis was performed on a 55-year-old male patient with an active lifestyle who developed severe arthritis in the left ankle. Over the follow-up period, high tibial valgization osteotomy was conducted for painful medial knee joint arthritis with genu varum deformity to correct overall lower limb alignment from varus to valgus with respect to the fused ankle. This study was conducted to investigate how hindfoot alignment would change when the overall alignment of the lower limb shifted from varus to valgus with the ipsilateral ankle in a fused state. Conclusively, while no intrinsic changes in the hindfoot alignment were observed following the alteration of lower limb alignment, the hindfoot naturally adjusted to valgus deviation in response to limb valgus realignment. Moreover, symptoms changed in line with this adjustment. Given the absence of similar case studies or reports, a review of relevant literature is included to contribute to knowledge of this subject.

PURPOSE: This study researched the effects of different types of high heels on the muscles surrounding the cervical spine, the thoracic spine, and the lumbar spine by analyzing muscle activation of the paraspinal muscles during walking while wearing high heels. The high heels were all of the same height: 8cm. METHODS: The 28 subjects in this experiment were females in their 20s with a foot size of 225-230mm. To measure the muscle activation of the paraspinal muscles, EMG electrodes were attached on the paraspinal muscles around C6, T7, and L5. The muscle activation during walking while wearing 8cm high wedge heels, setback heels, and french heels was measured. The measurements were performed 3 times each and the mean value of the result was used for analysis. Two kinds of velocity were used in this study. One of the velocity was 2.5 m/s. The other was 3.5 m/s. RESULTS: The muscle activation of paraspinal muscles increased significantly according to increase of walking velocity. But there was no significant difference according to the heel types. CONCLUSION: In view of the results, the height of heels and the velocity of walking are more convincing variables than the width of the heels on the muscle activation of paraspinal muscles. So wearing high heels is not recommended for those who have pain or functional problem of cervical and lumbar vertebrae.

Even though there were no clear definitions of the short game and short game distance, short game capability is crucial for a good golf score. Generally, chip shot and pitch shot are regarded as two principal components of the short game. Chip shot is a short, low trajectory shot played to the green or from trouble back into play. Pitch shot is a high trajectory shot of short length. Biomechanical studies were conducted usually to analyze full swing and putting motions. The purpose of the study was to reveal the kinematical differences between professional golfers' 30 yard $53^{\circ}wedge$ chip shot and $56^{\circ}wedge$ pitch shot motions. Fifteen male professional golfers were recruited for the study. Kinematical data were collected by the 60 Hz three-dimensional motion analysis system. Statistical comparisons were made by paired t-test, ANOVA, and Duncan of the SPSS 12.0K with the $\alpha$ value of .05. Results show that both the left hand and the ball were placed left of the center of the left and right foot at address. The left hand position of the chip shot was significantly left side of that of the pitch shot. But the ball position of the pitch shot was significantly right side of that of the chip shot. All body segments aligned to the left of the target line, open, at address. Except shoulder, there were no significant pelvis, knee, and feet alignment differences between chip shot and pitch shot. These differences at address seem for the ball height control. Pitch shot swing motions(the shoulder and pelvis rotation and the club head travel distance) were significantly bigger than those of the chip shot. Club head velocity of the pitch shot was significantly faster than that of the chip shot at the moment of impact. This was for the same shot length control with different lofted clubs. Swing motion differences seem mainly caused by the same shot length control with different ball height control.
