The purpose of this study was to compare the ring lock type knee-ankle-foot orthosis (KAFO) with newly developed 4-bar linkage KAFO on the gait characteristics of persons with poliomyelitis clinically. This 4-bar linkage is the stance control type KAFO which provide the stability during stance phase and knee flexion during swing phase. Two subjects participated in this study voluntarily. We provided the customized 4-bar linkage KAFO then asked the subjects to walk in level surface and stairs under the two different KAFO conditions. The characteristics of gait in the persons with poliomyelitis were evaluated using a 3D motion analysis system and force plate. Additionally 6 minute walk test for physiological cost index were conducted using pulse oximeter to measure the energy consumption. In the results of this study, the differences of 4-bar linkage KAFO compared with ring lock type KAFO are as follows: (1) Walking speed, stride length, and step length on level increased in subjects, (2) The gait symmetry was improved by generated knee flexion and decreased pelvic external rotation on level and stairs walking, (3) Decreased vertical excursion of center of mass and pelvic elevation during swing phase was decreased on level, (4) Knee extension moment, hip flexion moment, hip and knee internal rotation moment of non-braced limb were decreased on level walking, (5) Walking speed in 6-minute walk test was increased and physiological cost index was decreased. These findings indicate that 4-bar linkage KAFO compared with ring lock type KAFO is effective in enhancing pattern, endurance, and energy consumption in level surface and stairs walking.

Purpose: We analysis the outcome and complications of treatment of lesser toe brachymetatarsia. Materials and Methods: We analysed 28 patients 35 cases of lesser toe brachymetatarsia. Mean post operative follow up period was 2 years 8 months. All of the patients were female and mean age at operation was 21 years old. 2 cases of third metatasal bone and 33 cases of fourth metatarsal bone were operated. 8 metatarsal bones were treated using one staged lengthening with tricortical bone graft and 27 metatarsal bones were treated using callotasis with monofixator. Results: The average amount of lengthening was 13.3mm(12mm-15mm) in one staged lengthening, while 14.4mm(4mm-23mm) in callotasis. Average percentile increase was 28.9%(26%-34%) in one staged lengthening and 32%(18%-46%) in callotasis. The average healing index of callotasis was 76 days/cm (41 days/cm-166 days/cm). Satisfied outcomes in 4 cases of 8 cases (50%) after one staged lengthening and 17 cases of 27 cases (63%) after callotasis. 6 complications in 4 cases were occurred after one staged lengthening; insufficient length gain in 3 cases, fracture on the junction of graft bone and metatarsal bone in 1 case, plantar bowing deformity in 1 case and bony fusion of metatarsophalangeal joint in 1 case. 17 complications in 10 patients were occurred after callotasis ; metatarsophalangeal joint stiffness in 8 cases, metatarsophalangeal joint subluxation in 2 cases, overlengthened metatarsal bone in 2 cases, tapering of callus in 1 case, fracture of callus in 1 case, premature consolidation of callus in 1 case, osteomyelitis of metataral head in 1 case and plantar bowing deformity in 1 case. Conclusion: Although one staged lengthening and gradual lengthening using callotasis are effective treatment for lesser toe brachymetatarsia, complications not rarely occured after lengthening. Insufficient lengthening are most common complication after one staged lengthening while metatarsophalangeal joint stiffness lire most common complication after callotasis.

Objectives: The purpose of this study is to collect and analyze the KCD codes applied to the treatment of 27 postpartum women who had been treated with Korean traditional medicine in a Korean medicine hospital, so that this study may be used as a basic data for setting the direction of postpartum Korean medical treatment research. Methods: It was approved by the Institutional Review Board (IRB) of ${\bigcirc}{\bigcirc}$ University medical center (IRB approval number : WSOH IRB H1708-02-01). Twenty-seven postpartum women who had been treated at ${\bigcirc}{\bigcirc}$ University medical center were received outpatient treatment for two weeks (from September 27, 2017 to January 5, 2018), and the KCD codes applied to the mothers were collected after obtaining the consent. On the day of registration of the study, the fertility, obstetric history and high-risk pregnancies were identified through an interview. Results: 1. The mean age of the 27 subjects was $33.33{\pm}3.99\;years$ old. Among the subjects, 17 mothers (63.0%) were high-risk pregnancy and 10 mothers (37.0%) were normal. 2. Among the 22 major disease categories, 8 categories were used. M code (musculoskeletal system) was used 243 times (70.85%), followed by R code (unclassified symptom) of 51 times (14.87%) and U code (special purpose code) of 23 times (6.71%). 3. The most commonly used code among the ten frequently used codes was M25.57 (joint pain, ankle and foot), a total of 47 times. Of the remaining nine codes, except for R60.1 (systemic edema) and U68.4 (The deficiency of yang in Bi), all codes were M codes (musculoskeletal system). 4. The M code (musculoskeletal system) was the most used major disease category in high-risk group, a total of 159 times. But in specific categories, the most commonly used code was R60.1 (systemic edema), a total of 28 times. 5. In normal group, the M code (musculoskeletal system) was the most used major disease category, a total of 84 times. Also, in specific categories, the most commonly used code was M25.57 (joint pain, ankle and foot), total 29 times. 6. The U code, corresponding to 'the diagnosis of childbirth and other obstetrical medical use', was used 23 times (6.71%), O code three times (0.87%) and Z code two times (0.58%), which was less than 10% of the total number of codes used. Conclusion: When analyzing KCD codes related to Korean medicine treatment for postpartum diseases, it is important to select the KCD codes that reflect the actual clinical state.

Purpose: The purpose of this study is to evaluate the efficacy of mesenchymal stem cell (MSC) isolation by the magnetic-activated cell sorting (MACS) method in tendon tissue-derived cells compared to the colony picking method for isolation of MSCs by picking colony-forming cells. Materials and Methods: Human tendon-derived cells were isolated by enzyme digestion using normal tendon tissues from three donors. We used the magnetic kit and well-known MSC markers (CD90 or CD105) to isolate MSCs in tendon-derived cells using MACS. Cloning cylinders were used to isolate colony-forming cells having MSC characteristics in tendon-derived cells. Colony-forming unit-fibroblast (CFU-F) assay was used to evaluate the self-renewal capacity of cells isolated using the colony picking method or MACS. For comparison of differentiation potentials into osteogenic or adipogenic lineage between two groups, alizarin red S and oil red O staining were performed at 14 days after induction of differentiation in vitro. Results: Flow cytometry results showed that early passage tendon-derived cells expressed CD44 in 99.13%, CD90 in 56.51%, and CD105 in 86.19%. In the CFU-F assay, CD90+ or CD105+ cells isolated with MACS showed larger colony formation in size than cells isolated using the colony picking method. We also observed that CD90+ or CD105+ cells were constantly differentiated into both osteogenic and adipogenic lineages in cells from all donors, whereas cells isolated using the colony picking method were heterogeneous in differentiation potentials to the osteogenic and adipogenic lineages. Conclusion: CD90+ or CD105+ cells isolated using MACS showed superior MSC characteristics in the self-renewal and multi-differentiation capacities compared with cells isolated using the colony picking method.

Purpose: This study examined the effects of beraprost sodium on digital infrared thermal images in patients with peripheral arterial disease caused by type 2 diabetes mellitus. Materials and Methods: Twenty-five diabetic patients with peripheral arterial disease were treated with beraprost sodium in a prospective, multicenter, cohort study from February 2013 to December 2014. Beraprost sodium ($40{\mu}g$) was administered orally 3 times daily ($120{\mu}g/day$) for 6 months. The visual analogue scale (VAS) and digital infrared thermal imaging (DITI) were performed to compare the blood flow improvement between before and after dosing. Results: Among the 25 patients included in the evaluation, 22 patients completed the study. A significant increase in body temperature was observed in the front and left side, particularly in the plantar side in DITI compared to that before and after administration. An increase in body temperature was observed at the frontal part from $28.1^{\circ}C{\pm}2.3^{\circ}C$ to $29.1^{\circ}C{\pm}2.1^{\circ}C$ (p=0.021), at the left side from $27.8^{\circ}C{\pm}2.4^{\circ}C$ to $28.6^{\circ}C{\pm}1.9^{\circ}C$ (p=0.028), at the plantar part at $24.0^{\circ}C{\pm}1.5^{\circ}C$, and at the plantar part at $27.1^{\circ}C{\pm}2.4^{\circ}C$ (p<0.01). The VAS decreased significantly from $5.4{\pm}1.3$ to $2.7{\pm}2.0$ after 6 months of treatment (p<0.01). Conclusion: Beraprost sodium is a safe and easy-to use oral medication for diabetes peripheral arterial disease. It can be expected to increase the blood flow and decrease the lower extremity pain statistically after being taken for 6 months.

Purpose: We try to retrospectively evaluated the amount of dorsal angulation angle of the first metatarsal commonly occurring as the complication of proximal dome osteotomy for hallux valgus. Materials and Methods: Between January 2004 and March 2004, 34 patients who underwent proximal dome osteotomy for moderate to severe hallux valgus. Two of 34 patients were male, and thirty-two were female. The average age was 57.6 years. We measured and compared hallux valgus angle, 1st-2nd intermetatarsal angle, dorsal angulation angle of 1st metatarsal on preoperative, postoperative, postoperative 3 weeks', postoperative 3 months' X-ray. Results: Osteotomy sites were completely united on plane X-ray in all cases. The hallux valgus angle averaged $41.2^{\circ}$ ($30{\sim}60^{\circ}$) at preoperative, $4.3^{\circ}$ ($-10{\sim}20^{\circ}$) at postoperative, $5.5^{\circ}$ ($-1{\sim}20^{\circ}$) at 3 weeks after operation, $7.8^{\circ}$ ($-2{\sim}20^{\circ}$) at 3 months after operation. The 1st-2nd intermetatarsal angle averaged $17.1^{\circ}$ ($12{\sim}24^{\circ}$) at preoperative, $6.3^{\circ}$ ($0{\sim}13^{\circ}$) at postoperative, $7.2^{\circ}$ ($0{\sim}15^{\circ}$) at 3 weeks after operation, $8.7^{\circ}$ ($0{\sim}18^{\circ}$) at 3 months after operation. The dorsal angulation angle averaged $0.4^{\circ}$ ($0{\sim}3^{\circ}$) at postoperative, $1.6^{\circ}$ ($0{\sim}7^{\circ}$) at 3 weeks after operation, $2.1^{\circ}$ ($0{\sim}8^{\circ}$) at 3 months after operation. There were no statistically correlation between increase of dorsal angulation angle of the distal segment of the first metatarsal and increase of hallux valgus angle or 1st-2nd intermetatarsal angle. Conclusion: Our results shows that the dorsal angulation of distal fragment occurring after the proximal dome osteotomy in the treatment of hallux valgus may be minimized with meticulous surgery and patient's education.

Purpose: The purpose of this study is to determine the correlation between the correction loss of hallux valgus angle and the severity of valgus angle of the second toe. Materials and Methods: We selected 312 cases from 268 surgical patients with hallux valgus deformity receiving distal chevron osteotomy. For a radiological evaluation, we analyzed the changes in the hallux valgus angles, first to second intermetatarsal angles, and valgus angle of the second toe post index operations. All patients were women; the mean age was 46 years. The mean follow-up period was 17 months. Results: The mean hallux valgus angle was $33.6^{\circ}$ preoperatively (range, $25.7^{\circ}{\sim}44.8^{\circ}$), $13.1^{\circ}$ (range, $8.4^{\circ}{\sim}16.4^{\circ}$) after 4 weeks of postoperative period, and $17.1^{\circ}$ (range, $9.4^{\circ}{\sim}28.5^{\circ}$) at their final follow-up. The mean valgus angle of the second toe was $8.4^{\circ}$ preoperatively (range, $2.0^{\circ}{\sim}25.8^{\circ}$) and $8.3^{\circ}$ (range, $1.7^{\circ}{\sim}24.9^{\circ}$) at the final follow-up. Preoperatively, there was a positive correlation between the valgus angle of the second toe and hallux valgus angle (r=0.747, p=0.001). The correction loss of hallux valgus angle had a significant correlation with the severity of valgus angle of the second toe (r=0.802, p=0.001). Conclusion: The existence of the second toe valgus deformity may present itself as a cause of correction loss of hallux valgus angle. The preoperative measurement of the second toe valgus angle may be a good predictor of correction loss; therefore, thorough preoperative warning on the possibility of correction loss should be conducted to maximize patient satisfaction after the procedure.
