목 적 : 상완골 간부 분쇄 골절의 치료에서 최소 절개를 통한 관혈적 정복 및 교합성 골수강내 금속정 고정술의 치료 결과를 금속판 내고정술과 비교하고자 한다. 대상 및 방법 : 1997년 3월부터 2001년 12월까지 상완골 간부 골절로 금속판 내고정술을 시행한 14례와 상완골 간부 분쇄골절에 대해 최소 절개를 통한 관혈적 정복 및 교합성 골수강내 금속정 고정술을 이용하여 수술을 시행한 18례이고, 최고 9개월 이상 추시하였으며 임상적 및 방사선학적 결과를 분석하였다. American Shoulder and Elbow Surgeon's (ASES) shoulder score를 기준으로 기능적 평가를 하였고, visual analous scales에 따라 통증의 정도 (zero : no pain ~ 10 : extreme pain) 를 평가하였다. 결 과 : 골절 유합은, 금속판 내고정술의 경우 14례중 12례(85.7%)에서 골유합을 얻었고 골유합 시기는 평균 13.2주 이었다. 최소 절개를 통한 관혈적 정복 및 교합성 골수강내 금속정 고정술을 이용하여 수술을 시행한 18례중 17례(94.4%)에서 골유합을 얻었고 평균 골유합 시기는 평균 12.4주 이었다. ASES shoulder score에 따른 기능적 점수는 금속판 내고정술의 경우 평균 44점, 최소 절개를 통한 관혈적 정복 및 교합성 골수강내 금속정 고정술을 시행한 경우 평균 47점 이었다. 통증의 정도는 금속판 내고정술의 경우 평균 1.8, 최소 절개를 통한 관혈적 정복 및 교합성 골수강내 금속정 고정술을 시행한 경우 평균 1.4 이었다. 결 론 : 상완골 간부 분쇄골절에 대한 최소 절개를 통한 관혈적 정복 및 교합성 골수강내 금속정 고정술은 견고하고 정확한 골절의 정복이 가능하고 술후 방사선학적 및 기능적 결과가 다른 수술방법에 비해 결과가 좋은 것으로 사료되었다. Purpose : We compared the functional and radiological results after the minimal open reduction and interlocking IM nailing and LC-DCP plate internal fixation for the comminuted humeral shaft fractures. Materials and Methods : Fourteen plates(LC-DCP) and eighteen interlocking IM nail (AO unreamed IM nail) were applied after open reduction for 21 comminuted fractures of the humeral shaft between March 1997 and December 2001. They were followed up for a minimum 9 months after surgery and the radiological and functional results were evaluated. Results : The average fracture healing time was 13.2 weeks and union rate was 85.7% for plate internal fixation. The average fracture healing time was 12.4 weeks and union rate was 94,4% for interlocking IM nail. The average functional scores according to American Shoulder and Elbow Surgeon's (ASES) shoulder score(Total 52 points_ was 44 points for plate internal fixation and 47 point for interlocking IM nailing respectively. Conclusion : Minimal open reduction and interlocking IM nailing is better method with good functional and radiological results than plate internal fixation for the comminuted humeral shaft fractures.

Purpose: The diabetic charcot neuroarthropathy of ankle is an infrequent site (around 5%), but is definitely the location that, because of the instability and progressive deformity it involves, cause ulceration in a high percentage of patients, and this can then become a reason for amputation. However, the treatment of this disastrous disease is still challenging. We analyzed the clinical and radiological results of ankle arthrodesis by our fixation method in Charcot neuroarthropathy. Materials and Methods: Seven cases that were diagnosed as charcot neuroarthropathy of ankle arthrodesis were followed for more than 16 months postoperatively. Mean age was 57 years, and the mean follow-up period was 27 months. Anterior approach was used in arthrodesis, and internal fixation by 3 or more cannulated screws and hybrid type external fixation were used. Auto iliac bone for grafting was combined in all cases. External fixator was kept for 3 months without weight-bearing. Then, boots brace was applied for more 3 months allowing partial weight-bearing. Four cases had minor complications such as pin site infection. Preoperative and postoperative AOFAS score, time to fusion and postoperative complications were checked. Results: Postoperative fusion was completed in all cases, and the mean time to fusion was 3.4 months. No postoperative complication was checked. At the last follow-up, the mean AOFAS score had increased from 54 points to 72 points. Patient's satisfaction was over 80%. Conclusion: Satisfactory results were obtained after ankle arthrodesis using internal and hybrid type external fixation combined with auto iliac bone graft in charcot neuroarthropathy with minor complications.

특집1: 『아가 I』을 중심으로 살펴 본 이상근의 예술가곡

한경진 민족음악학회 2010 음악과 민족 Vol.39 No.-

In his thesis issued in 1955, he revealed his philosophy and view of music including Korean art songs. He mentioned the importance of the selection of text, research on Korean texts, and exploration of compositional technique over not just Korean music but also Western music. This article aims to research his art songs focusing on “Aga I, II (1969, 1988)” which shows his musical identity very well and concrete aspects of musical idioms used in his vocal works. Each voice and piano part in “Aga I, II” is generally based on different sound background. While melodies in the voice part have relatively tonal background, chord progressions in the piano part are characterized by coloristic, nonfunctional harmony. Various combinations of these two parts contribute to produce unique and effective sound in his songs. Also, the relationship of the voice part to the piano is not the same as the traditional one. The piano is not just an accompaniment but also takes a very active role in his songs. The piano frequently leads the voice and consists of an exploration and elaboration of thematic materials. Furthermore, the composer attempted to explore possibilities of determination and transformation of musical materials through various compositional techniques in all genres of his works. Whereas the influence of French Impressionism, particularly that of Debussy, were noticeable in the works of his early period, he has created his identity through in his works thereafter. He was keen to use Korean material in his vocal works and made successful results on many stages through extreme elaboration of sounds.

The purpose of this study was to investigate changes of isokinetic muscle strength proprioceptive function as exercise time duration after ankle taping in baseball players. For this study, thirty highschool baseball players whose had no ankle injuries were volunteered, and all subjects were randomly divided into two groups (TG -taping group, n=15 and CG - control group, n=15). Dominant side ankles of all subjects in TG were taped by closed basketweave technique before exercise. For exercise stimulation, 10, 20, 30 and 40 minutes of running exercise was carried out on the treadmill (10km/h, 0%) with 48 hours intervals. Cybex 770 Model(Lumex, U.S.A) was used to measure isokinetic muscle strengths at 30°/sec and 120°/sec angular velocity, and then peak torque % body weight and average power % body weight were collected to analyze. To measure proprioceptive function, hop test and Romberg test were conducted. To analyze the datas, repeated measured two way ANCOVA and T-test were used and significance was set at p<.05 for all tests. The results are as follows; 1) Isokinetic muscle strengths of plantar flexor were significantly decreased by taping(p<.01). 2) Power of dorsi flexor, plantar flexor and eversor were significantly decreased by taping(p<.05). 3) The distance of hop test after exercise were significantly increased compared to before exercise in TG, and the distance of hop test at 20 min after exercise were significantly increased compared to before exercise in CG. 4) The duration of Romberg test of all measurements were significantly decreased in TG compared to CG. The duration of Romberg test at 10 min after exercise were significantly increased compared to before exercise and then significantly decreased at 20 min after exercise and these at 10 min after exercise were significantly increased compared to 20 and 30 min after exercise in TG. In conclusion, taping on ankle can have an negative effect on ankle muscle strength, power, proprioceptive function and when baseball players need taping, exercise duration should be considered.

A 3-year-old, 26 kg, castrated male Chow Chow was presented for assessment of weight-bearing lameness of the left hind limb. The patient had a history of triple pelvic osteotomy on the left side to correct hip dysplasia 2 years prior to his presentation of clinical signs and underwent total hip replacement on the right coxofemoral joint 1 year later. Upon physical examination, pain and crepitus were noted on the left hip joint during extension. Radiological examination revealed coxofemoral joint subluxation and moderate degenerative bone changes on the left hip joint and pelvic axis, which relates to acetabular angles that were changed after triple pelvic osteotomy (TPO). Preoperative computed tomography was used for 3-dimensional printing to establish an accurate surgical plan. The changed angles of the acetabulum after TPO were evaluated, and rehearsal surgery was performed using a 3-demensional printing bone model. Three months after the THR surgery, the function of the affected limb had improved, with no lameness. Complications, such as luxation and implant failure, were not observed until 6 months after the operation. Accurate evaluation of acetabulum angles and rehearsal surgery using a 3D-printed bone model is effective for total hip replacement after unsuccessful TPO.

The purpose of this article to evaluate the availability of the rectus femoris flap in Korean subjects. Material and Methods is that Cadaveric dissections were done on 51 femoral triangles of 26 cadevers. We measured the length of the direct head of rectus femoris from anterior superior iliac spine to patella upper pole, ASIS to lateral border of femoral nerve, and entry point of femoral nerve and vessel branches to rectus. Usually, there were three terminal branches to rectus femoris from the femoral nerve. The entry point of the first branch was at the proximal $17.5{\sim}31.4%$ portion of the rectus femoris. The second and the third branch entered at the proximal $22.5{\sim}40.7%$ and $26.3{\sim}42.3%$, respectively. The vessel entry was at $20.2{\sim}37.3%$. The length from ASIS to femoral nerve was $3.5{\sim}8.5\;cm$. Among the 51 rectus femoris muscles, 44 had one nutrient artery, and 7 had 2 nutrient arteries. The nutrient artery originated from the descending branch of the lateral femoral circumflex artery in 18(40.9%) cases, directly from the lateral femoral circumflex artery in 8(18.0%) cases, and from proximal(6 cases, 13.6%) and distal(12 cases, 27.3%) portion of the deep femoral artery. The average length of the nutrient artery was 29.8 mm and the width was 2.14 mm. The point where it meets the main feeding artery of the rectus femoris was $9.0{\sim}15.0\;cm$ from the ASIS. In all cases, the main artery's entrance was proximal to the first nerve branch. Conclusion is that rectus femoris has available data for functional flap.
