Purpose: Recurrence is one of the most common complications after primary correction for hallux valgus deformities. The purpose of this study was to evaluate the usefulness of Scarf osteotomy with axial decompression in the treatment of recurrent hallux valgus. Materials and Methods: From April 2006 to April 2011, 14 cases (12 patients) of recurrent hallux valgus were managed with shortening Scarf osteotomy. Preoperative and postoperative radiographs were reviewed for the measurement of the hallux valgus angle (HVA), intermetatarsal angle (IMA), and the amount of the $1^{st}$ metatarsal shortening. Clinical outcomes including the visual analogue scale (VAS), the AOFAS score, and the range of motion [ROM] of the 1st metatarsophalangeal (MTP) joint were evaluated. Results: The mean HVA decreased from 27.9 degrees to 5.2 and the mean IMA decreased from 12.9 to 3.4. The mean VAS improved from 5.3 to 0.3 and the mean AOFAS score improved from 41 to 90. The mean amount of the 1st metatarsal shortening was 3.4 mm (2-5). The mean ROM of the $1^{st}$ MTP joint improved from 22 degrees (15-35) to 68 (55-75). Conclusion: Scarf osteotomy associated with axial decompression can be a useful revision procedure for the treatment of recurrent hallux valgus deformity.

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: We described our experience with subungual exostosis in the foot for which we used different surgical technique according as location and size of lesion and revealed excellent results. Materials and Methods: We experienced 12 cases of subungual exostosis that were treated surgically and followed them more than one year between October 1995 and July 2003. There were nine females and three males. The average age of patients at surgery was 13.4 years. Duration of symptoms was 20.3 months on average. The lesion involved the hallux in nine cases; eight dorsomedial and one dorsolateral aspect of distal phalangeal bone. It involved the second, the third, and the fifth toe in one each; all central aspect of dorsum of distal phalanx. We used surgical technique that involves approaching the exostosis under the nail to preserve nail coverage for lesion in the hallux. The nails were extracted totally but preserved nail bed as much as possible in other toes. Results were based on appearance of the regenerated nail and presence of recurrence. Excellent results were those in which the nail appeared nearly normal and there was no clinical or radiographic evidence of recurrence. Good results were associated with a minor nail deformity such as ridging, and no evidence of recurrence. Fair results had obvious nail deformity or a minimal asymptomatic recurrence that was discernable only on radiograph. Poor results were associated with a clinically evident symptomatic recurrence. Results: When the lesion involved hallux, there were six excellent and two good results, and one poor result. All cases that involved other toes revealed good results. Conclusion: We suggest that different surgical technique might be applied according as location and size of the lesion to achieve satisfactory results for subungual exostosis in the foot.

Purpose: To evaluate the short-term results of medial displacement calcaneal osteotomy without flexor digitorum longus transfer for flexible flatfoot deformity. Materials and Methods: Twenty four patients (25 feet) who had undergone medial displacement calcaneal osteotomy without flexor digitorum longus transfer for flexible flatfoot between July 2004 and May 2007 were included. The mean age was 43.6 years (16~78 years). The mean follow-up was 26 months (14~50 months). Clinical outcomes were assessed using American Orthopaedic Foot and Ankle Society (AOFAS) score and visual analogue scale (VAS). Six radiographic parameters were measured from weightbearing radiographs to assess the difference between preoperative and postoperative radiographs. Results: The mean AOFAS score improved from 57.9 points preoperatively to 89.2 points at latest follow-up (p=0.000). The mean VAS improved from 62 points preoperatively to 23 points at latest follow-up (p=0.000). The mean talonavicular coverage angle on anteroposterior (AP) view changed from 20.2 degrees to 16.0 degrees (p=0.002). The mean calcaneal pitch angle on lateral view changed from 12.6 degrees preoperatively to 14.5 degrees at latest follow-up (p=0.001). Regarding these radiographic parameters, the difference between interobserver measurements was larger than that between pre- and post-operative measurements. The calcaneus was transferred medially by average 11.8 mm (p=0.003), which was 27.9% of the width of calcaneal tuberosity (p=0.000). The mean talo-first metatarsal angle on AP and lateral views, and navicular height on lateral view were not significantly changed. Conclusion: Medial displacement calcaneal osteotomy without flexor digitorum longus transfer for flexible flatfoot could lead to improve the clinical outcomes, although the restoration of medial longitudinal arch was not clinically significant.
Purpose: To study the reliability of intra- and interobserver reliability in angular measurement of hallux valgus deformity by assessing hallux valgus angle (HVA) and the 1st to 2nd intermetatarsal angle (1-2 IMA) through using computerized system. Materials and Methods: 20 cases of moderate to severe hallux valgus patients were included in this study. With the standing anteroposterior view of foot, the HVA and 1-2 IMA were calculated by computerized measurement system of Infinity cooperation, called ${\pi}$-view, with its software tools. Using the statistical software program, SPSS (version 12th), we interpreted the results which were measured by two independent observers. Results: In the intraobserver measurement, the HVA of observer A showed reliability ($32.5^{\circ}{\pm}6.9$ and $33.1^{\circ}{\pm}6.8$)(p<0.05). 1-2 IMA in observer A was not regarded as reliable ($16.9^{\circ}{\pm}2.8$ and $17.1^{\circ}{\pm}2.8$)(p>0.05). In the results of observer B, HVAs were measured as $35.7^{\circ}{\pm}7.6$ and $36.2^{\circ}{\pm}7.7$, and were not reliable (p>0.05). 1-2 IMA in observer B was not reliable as well ($17.0^{\circ}{\pm}0.8$ and $20.8^{\circ}{\pm}1.5$)(p>0.05). In the interobservers' measurements, the first and the second results of HVA were $3.2^{\circ}{\pm}3.6$ and $3.1^{\circ}{\pm}3.1$, reliable within the 95% confidence interval (p<0.05). 1-2 IMAs were $0.1^{\circ}{\pm}1.9$ and $3.73^{\circ}{\pm}1.3$, which were not reliable (p>0.05). Conclusion: In the angular measurement of the hallux valgus by computerized system, the HVA and 1-2 IMA showed less error range in the interobserver's results, compared with the previous studies about the manual measurement. However, our results failed to show the statistical reliability of intra- and interobserver's measuring. Therefore, even the computerized angular measurements in the severity of hallux valgus require development of the measuring methods and software tools.

Purpose: This study compared the functional and cosmetic treatment outcomes of intramedullary nailing (IM nail) and minimally invasive plate osteosynthesis (MIPO) for distal tibia shaft fractures. Materials and Methods: Forty-eight patients with distal tibia shaft fractures (distal 1/3 of the diaphysis, AO/OTA [AO Foundation/Orthopaedic Trauma Association]) 43 managed by an IM nail (n=30) or MIPO (n=18) who had minimum one-year follow-up were enrolled in this study. The radiological, functional, and cosmetic outcomes in the two groups were compared retrospectively. Results: All patients achieved bone union. The mean bone union time of the IM nail and MIPO groups was 18.5 and 22.6 weeks, respectively (p=0.078). One patient in the MIPO group showed posterior angulation and valgus deformity of more than five degrees. The mean American Orthopaedic Foot and Ankle Society (AOFAS) functional scores were similar: 83.3 in the IM nail group and 84.6 in the MIPO group (p=0.289). The most salient difference was the cosmetic result of the surgical scar. The length of the scars around the ankle in the IM nail group was significantly smaller than the MIPO group (2.6 cm vs. 10.6 cm; p=0.035). The patient satisfaction survey of surgical scars revealed a significantly higher satisfaction rate in the IM nail group than in the MIPO group (93% vs. 44%; p<0.001). Conclusion: This study showed that both treatment methods for distal tibia shaft fractures have similar therapeutic efficacy regarding the radiological and functional outcomes. On the other hand, the IM nail technique showed superior cosmetic outcomes than the MIPO technique. IM nails may be more recommended in patients with high demand for cosmetic results.

Purpose: A rheumatoid forefoot deformity includes severe hallux valgus and claw toe of the four lateral toes. The authors intended to analyze the mid-term results of the modified Hoffman procedure for a rheumatoid forefoot deformity. Materials and Methods: Twenty-two feet of eighteen patients were followed up for more than two years after the modified Hoffman procedure. The mean age was 54.7 years, and the mean follow-up period was three years and four months. Clinically visual analogue scale (VAS) and American Orthopaedic Foot and Ankle Society (AOFAS) MP-IP score were analyzed preoperatively and postoperatively. The postoperative complications, the satisfaction of patients, and the presence of plantar callosity were also analyzed. Radiographically, the hallux valgus angle, the 1st intermetatarsal angle, the 1st interphalangeal angle, the 1st interphalangeal joint arthritic change after the operation, and the dorsiflexion angle and the time to union of the 1st metatarsophalangeal joint were analyzed. Results: Clinically, the VAS and AOFAS score were respectively improved from 7.1 points and 30.3 points preoperatively to 1.5 points and 83.1 points postoperatively (p<0.001). All patients were satisfied with the results. Plantar callosity disappeared in all cases. Radiographically, the mean hallux valgus angle, the 1st intermetatarsal angle, and the 1st interphalangeal angle changed from 52.8°, 13.3°, and 7.5° preoperatively to 16.2°, 8.7°, and 14.6° postoperatively (p<0.001). The mean dorsiflexion angle of the 1st metatarsophalangeal joint was 17.2° postoperatively. The mean time to radiographic union of the 1st metatarsophalangeal joint was 11.1 weeks. There were two cock-up deformities of the lesser toe, one wound problem, and two hallux interphalangeal joint arthritis as a complication. There were no cases of nonunion of the 1st metatarsophalangeal joint. Conclusion: The modified Hoffman procedure appears to be a safe and satisfactory procedure for a rheumatoid forefoot deformity.

Purpose: The authors evaluated the differences between K-wires and Bold screw for fixing the proximal metatarsal chevron osteotomy of moderate and severe hallux valgus. Materials and Methods: There were 59 patients (81 feet) who were moderate and severe degree hallux valgus according to the classification of Mann. They all got the proximal chevron osteotomy when correcting the deformity. All patients were followed up at least 6 months. We divided the patients into 2 groups, K-wires fixed group as A, Bold screw fixed group as B. Group A were 42 patients (63 feet) and Group B were 18 patients (19 feet). Among the Group B, 2 feet who were failed to fix the oetotomy site with Bold screw, were fixed with K-wires during operation. We measured the AOFAS score preoperatively, postoperatively and at final follow-up, VAS score at 2 weeks after the operation. Also preoperative, postoperative and follow-up hallux valgus angle (HVA) and intermetatarsal angle (IMA) were measured for each patients. Results: Mean follow up period was 1.34 year (range: 6 months-6.16 years). Mean VAS score of group A was $3.21{\pm}1.7$ and group B $1.76{\pm}1.0$. Preoperative mean AOFAS score of group A was $45.61{\pm}8.3$, group B $44.41{\pm}8.9$, the final mean score of group A was $88.87{\pm}8.3$ and group B $92.47{\pm}4.4$. Preoperative mean HVA was $30.82{\pm}6.6$ degrees in group A and $32.88{\pm}14.5$ degrees in group B, the final mean angle of group A was $14.89{\pm}8.3$ degrees and group B $17{\pm}4.4$ degrees. The preoperative mean IMA of group A was $13.69{\pm}3.6 $degrees and group B $12.35{\pm}5.2$, the final mean angle of group A was $9.26{\pm}3.6$ degrees and group B $12.35{\pm}5.8$ degrees. Conclusion: There were no statistical differences in radiologic and clinical results (p>0.05) but, group B exceeded group A in VAS score (p=0.0007) and had no statistical significance in terms of reduction angle loss (p=0.06). Early returning to normal life activity may be possible for patients using Bold screws.
The purpose of this study was to privide basic data for footwear development according to walking mechanics by comparing gait cycle difference between barefoot walking and walking shoes. The walking period was measured in 30 normal adult women with no foot deformity and abnormality. The first subject walked in sneakers and measured the cycle. And then, the subjects walked barefoot and the period was measured to obtain data. The data were taken form corresponding paired T-test. The results were as follows: In barefoot walking, the stance phase left side(p <.001), right side(p <.005), the loading response left side(p <.009), right side(p <.002) ), the pre-swing left side(p <.002), right side (p <.011), the double stance phase(p <.004) were increased and the mid-stance left side (p <.016), right side(p. 001), the swing phase left side(p<.001) was decreased. This suggests that barefoot walking increases the input of various senses of the foot, which makes stable walking possible. It is necessary to improve shoes based on the walking cycle in the future.
Purpose: Preshaped Locking compression plate(LCP) has holes with fixed angle between screw and plate and have advantage firm fixation because it has stability of angular and axial deformity. We evaluated usefulness of LCP after open reduction and internal fixation in distal fibular fracture. Materials and Methods: Between December 2011 and May 2012, 23 patients with fracture of distal fibula were followed up at least 12 months underwent open reduction and internal fixation with LCP. There were 15 males and 8 females with a mean age 39.8(20~69) years. According to Danis-Weber classification, there were 20 cases of type B and 3 cases of type C. There were 13 cases of isolated lateral malleolus fractures, 1 case of bimalleolar fracture, 6 cases of trimalleolar fractures and 3 cases of distal tibia fractures with proximal fibula fracture. Intraoperatively, we assessed whether preshaped LCP fit lateral margin of distal fibula or not and evaluated quality of reduction and postoperative complications. The cases were analyzed by radiological bone union time and clinical results according to the criteria of Meyer Results: Of all cases, complete bone union was achieved and average radiological bone union time was 7.3(6~12) weeks. The clinical results were excellent in 18 cases(78%), good in 5 cases(22%). There were 5 cases of plate with 3 holes, 13 cases of plate with 4 holes, 2 cases of plate with 5 holes, 1 case of plate with 6 holes and 2 cases of plate with 7 holes. The average number of screws at proximal fragement was 2.5 and at distal fragment was 3.5. In 14 cases (60.8 %), we needed re-bending of plate because the distance between plate and lateral cortical margin of distal fibula was more than 5 mm at anteroposterior X-ray after reduction. All cases have anatomical reduction and there were no complications of wound infections. There were no complaint about hardware irritation. Conclusion: At fractures of distal fibula,preshaped LCP had a excellent stability although far cortex was not fixed with screw and bending of plate. And there are less complications of hardware irritation and wound problems. But, Some complement would be needed because there were no complete fitting between precontour of LCP and lateral cortical margin of distal fibula.
