Supracondylar fracture of the femur can be treated by a wide variety of methods. Although satisfactory results have been achieved with either open and closed treatment, less certain results are obtained for the elderly who have pre-existing osteoarthritis and osteoporosis. Particularly, elderly patients who have preexisting osteoarthritis are at increased risk of posttraumatic arthritis, stiff knee, persistent pain. Primary total knee arthroplasty(TKA) might obviate many of these potential problems and help to return the high-risk patient to an ambulatory functional status immediately. There are few reports about this study. The purpose of this study is to evaluate the results treated by simultaneous internal fixation and TKA for the supracondylar fracture in the elderly who have osteoarthritis of the knee joint. From 1994 to 1998, eight primary TKAs using posterior cruciate sparing PFC knee(Press Fit Condylar, Johnson & Johnson, Raynham, U.S.A) were performed after internal fixation for the supracondylar fracture of the femur with Judet plate or condylar buttress plate by conventional means. Patella was not resurfaced in all knees. According to the M ller classification of the supracondylar fracture of the femur 5 fractures were type A, 2 in type B, 1 in type C. Five patients were female, 3 patients were male. The ages ranged from 66 to 81, with an average of 74 years. Patients were followed for at least 1 year(average 3 years). The mean interval between the injury and operation was 2 weeks(range, 1 week to 4 weeks). Active knee joint exercise was encouraged in a hinge brace under the postoperative pain control. Partial weight bearing was permitted at the postoperative 4 to 6 weeks using crutches. Full weight bearing was allowed after union of the fracture. Fractures were united in all patients and the average duration of bony union was 16 weeks. The average amount of flexion and average flexion contracture for the all patients at the most recent follow-up were 96 degrees (range, 45 to 120 degrees) and 7 degrees (range, zero to 20 degrees), respectively. Using the knee rating score advocated by the American Knee Society, the average postoperative score was 87 for pain and 80 for function. We concluded that simultaneous internal fixation and TKA for supracondylar fracture of the femur in elderly patients who have advanced knee osteoarthritis may provide satisfactory pain relief and function with acceptable morbidity.

Malignant peritoneal mesothelioma is a rare neoplasm that arises from the mesothelium of a serosal cavity and is a rapidly fatal disease with a median survival of 4 to 12 months for untreated cases. Recently, we experienced a case with malignant peritoneal mesothelioma who was suspected hepatocelluar carcioma by abdominal CT scan and was confirmed by biopsy including immunohistochemical stain(calretinin) after surgery. We performed tumor excisions and wedge resection of the liver(segment Ⅷ)and inserted Tencoff catheter in abdominal cavity at 25th day of post-operation. We treated with intraperitoneal paclitaxel(25mg/m^(2)/day for 5 days) six courses monthly. She was well tolerable and is still living without any evidence of recurrence for 14th month of post-operation.

Omental infarction, the end result of impaired perfusion to the greater omentum, is a rare benign self-limiting clinical entity. The main clinical symptom is non-specific localized abdominal pain with a moderately raised white blood cell and erythrocyte sedimentation rate. These findings often mimic an abdominal surgical emergency. This condition is often misdiagnosed as acute appendicitis or cholecystitis. The characteristic feature of CT scan and ultrasonography provide non-invasive diagnosis in most patients with omental infarction. We report a case of patient whose CT scan showed the characteristic finding of omental infarction. The patient was improved spontaneously only with conservative care.

Multiple fractures of the long bone shaft are not uncommon. There has been much controversies concerning over the method of its treatments due to their frequent complication rate. A randomized, prospective study of Ender nailing for multiple fracture of the long bone shaft of thirty-five cases in twenty-five patients was undertaken at the department of orthopaedic surgery, from January 1989 to Febrary 1995. The results are follows: The average age of the patients was 36-year-old and 20 patients were male and the most common cause was traffic accident. Among 35 cases, comminuted fractures were 10 cases and segmental fractures were 4 and others are transverse, short oblique fractures. Average interval from injury to operation was 2 days. Average bone union time. 1) Humerus : 11 week. 2) Femur : 20 week. 3) Tibia : 18 week. The most common complications were nail migration and superficial infection. The non-union developted in one case. From the result, Ender nailing is one of good treatment modality in open long bone fracture of grade Ⅰ, Ⅱ and selected grade Ⅲa, which provides low risk of complication and allows early weight bearing and ambulation without periosteal stripping in the long bone shaft fracture.

저자들은 1988년 3월부터 1994년 9월까지 진구성 방전십자인대 손상에 대하여 관절경하에서 슬개골-건-골을 이용하여 재건술을 시행한 환자중 1년이상 추시가 가능했던 30례의 환자를 대상으로 결과를 분석하여 다음과 같은 결과를 얻었다. 1) 남자가 많았고 30대가 가장 많았다. 2) 가장 많은 손상 원인은 교통사고였으며 17명의 환자에서 동반손상이 있었다. 3) 수상후 수술까지의 기간은 평균 9개월이었고 3개월부터 18개월까지 고른 분포를 보였다. 4) 가장 많은 동반손상은 내측부 인대 파열이었고 다음은 내측부 반월판 손상이었다. 5) 환자의 임상적 평가는 Lysholm knee scoring scale을 사용하였다. Two tunnel군에서는 최종 평가시 79%에서 양호 이상의 소견을 보였고, One tunnel 군에서는 81%에서 양호 이상의 소견을 보였다. 6) 10명의 환자에서 추시관절경을 시행하였으며 관절경 소견상 이식거늬의 생착과정을 확인할 수 있었다. 저자들은 관절경하에서 슬개골-건-골을 이용한 선방 십자인대 재건술을 시행하여 양호한 결과를 얻었고 향후 장기 추시가 필요할 것으로 사료되며 두 가지 수술 방법에 따른 뚜렷한 차이는 없었다. 또한 추시 관절경 검사는 이식건의 성숙 과정을 관찰하고 환자의 재활치료에 방침을 정하기 위해 필요하리라고 사료된다. Recent Arthroscopic ACL reconstruction methods have been developed as a technical solution to achieve proper positioning of the graft. In this study, ACL tear were treated with BTB autograft using either arthroscopic two tunnel method or one tunnel method. We analyzed the 30 cases who had taken the reconstruction surgery of ACL from March 1988 to September 1994. The results were as follows. In the two tunnel group, 79%(15 patients) were estimated as exellent or good result and 81%(9 patients) in the One tunnel group. Follow-up arthroscopy was perfomed to observe the maturation process of the graft in 10 cases. There was no clinical differences between two groups.

The arthroscopic surgery is an increasingly accepted procedure for the treatment of symptomatic arthritic knee. Authors reviewed the operative results of arthroscopic surgery in 35 knee joints of 27 patients from 1993 to 1997. 1. The average age of patients was 64 years old and the primary diagnosis was degenerative osteoarthritis in all patients. 2. Preoperative symptomes and signs were pain(98%), tenderness(85%), swelling(85%), decreased range of motion(71%) and effusion(55%). 3. The operative procedures were irrigation and synovectomy(20%), abrasion arthroplasty(57%), partial menisectomy and abrasion arthroplasty(23%). 4. The symptoms and signs were improved postoperatively: according to Nine point scale, the good results were recorded at postoperative 6 months and follow-up 2 years in nearly all patients. 5. The complications were minimal. Authors concluded that arthroscopic surgery is considered as a reliable method in the treatment of degenerative osteoarthritis of the knee but not as a curable method, needing a long term observation.

This paper proposes a double resonant high frequency inverter which reduces the distribution of the switching current. The analysis of the proposed circuit is generally described by using the normalized parameters. Also, the principle of the basic operation and the characteristics of driving were estimated by the switching frequency and the load parameters. And the data for the design were got by the characteristic values obtained from the characteristic estimation. At the same time the example of the design method was proposed. In addition, Comparing the theoretical waveforms to the experimental waveforms certified the operating characteristics of the proposed Inverter. It is certain that the proposed circuit will be used and expanded in the high frequency power supplies like induction heating systems.

페그인터페론과 리바비린 병합요법은 만성 C형 간염의 일차 치료법이다. 저자들은 만성 C형 간염 환자에서 페그인터페론 과 리바비린 병합 요법 중에 발생한 벨마비 1예를 경험하였기에 문헌고찰과 함께 보고하는 바이다. 환자는 5년 전부터 만성 C형 간염을 앓아온 48세 남자이며, PEG-IFN α-2a 135μgm 피하주사 주1회와 하루 1200㎎의 리바비린을 투여하였다. 치료시작 후 9개월째 환자는 오른쪽 안면의 근력약화를 호소하였으며 벨마비로 진단되었다. 페그인터페론과 리바비린 병합요법을 지속하면서 관찰하였다. 환자의 벨마비는 페그인터페론 치료를 중단하지 않았음에도 3개월후 증상이 회복되고 이후 벨마비 재발 없이 현재 경과관찰 중이다. 만성 C형 간염에서 페그인터페론과 리바비린 병합 요법시 벨마비의 발생 가능성을 염두에 두어야 하겠다. A Case of Bell's Palsy Associated with Combination Therapy of Pegylated Interferon Alfa-2a (PEG-IFN) and Ribavirin for Chronic Hepatitis C Virus Infection Pegylated interferon alfa(PEG-IFN α) and ribavirin therapy is the first line treatment for chronic hepatitis C. Mild complications of the therapy are common, but more serious complications are rare. We report here a case of Bell's palsy that occurred in a patient with chronic hepatitis C virus infection during combination therapy of PEG-IFN α-2a and ribavirin. The patient was 49-year-old man with chronic hepatitis C (genotype 1b) for 8 years. He had compensated liver cirrhosis with splenomegaly. Therapy with PEG-IFN α- 2a 135mcg/week and ribavirin 1200mg/day was initiated. After 9 months of the therapy, the patient showed a loss of muscular tone on the right side of his face. A diagnosis of Bell's palsy was made. The Bell's palsy resolved over 3 months despite continuation of the combination therapy.

An experimental study was designed to investigate the effects of 10-weeks exercise on the bone mineral density (BMD) in women (ages 55 to 74). The subjects were placed into two age groups; middle aged group(n=19, 62.2±2.5 yrs) old group(n=16, 69±2.3 yrs). All subjects completed the bone mineral density test ( Radius and Ulna) by computed tomography both prior to and immediately following 12-weeks program. Both experimental groups participated in an 12-week exercise program consisting of three 80-min supervised exercise bouts a week. A pairs T-test was used to examine differences between pre-and post-test scores in the bone mineral density, depending on each age group. First the significant improvement (1.7%) appeared on BMD in all subjects together after 10-weeks exercise. Specifically, the middle aged group showed statistically significant increase(1.2%) between pre-and post-test scores in he bone mineral density after 10-weeks program. However, even though the improvement (2.2%) of BMD in the older group was not significant in statistics, the improvement(2.2%) of BMD in the older group is bigger than the improvement (1.2%) of BMD in the middle aged group. Therefore, the results suggest that improvements in BMD may be affected by acute exercise and may support the affective beneficence of exercise for older populations.
