목적: 수술적 치료를 시행한 관절내 종골 골절의 전반적인 임상 양상과 술 후 최소 2년 이상 추시 결과를 분석하고, 술 후 1년째와 2년 이상 추시 결과를 비교하고자 하였다. 대상 및 방법: 1997년 3월부터 2002년 5월까지 관절을 침범한 전위된 종골 골절로 수술적 치료를 시행 후 최소 2년 이상 경과 추시가 가능하였던 39예 (34명)를 대상으로 Creighton-Nebraska 기능평가를 이용 전반적 술 후 결과를 분석하였고, 술 후 1년과 2년 이상 추시 결과를 비교 분석하였다. 결과: 골절 양상은 Sanders 분류상 II형이 13예 (33.3%), III형 (51.3%), IV형 (15.4%)의 분포를 보였다. 술 후 평균 추시 기간은 35개월 (범위: 24~87개월)이었고, Creighton-Nebraska 평가는 최종 추시상 76.0점 (범위: 30~100점)으로 1년 추시 평균인 67.1 점(범위: 22~95점)에 비해 유의하게 향상되었다 (p<0.05). 결론: 수술적 치료를 시행한 관절내 종골 골절에 대하여 술 후 2년 이상 주시 결과는 술 후 1년째 결과에 비해 유의하게 향상된 비교적 양호한 임상적 결과를 보여 종골 골절 수술 후의 경과는 최소 2년 이상의 시점에서 평가함이 바람직하다고 생각한다. Purpose: To evaluate the overall clinical features and postoperative functional results of the intra-articular calcaneal fractures at more than 2 years follow-up, and also to compare the results at postoperative 1 year with the results at more than 2-year follow-up. Materials and Methods: The study is based on 39 intra-articular calcaneal fractures (34 patients) that underwent surgical treatment from March 1997 to May 2002 with at least 2 years follow-up. The overall postoperative results were evaluated with Creighton-Nebraska functional scale. The comparison of results at postoperative 1 year was also performed with results at more than 2-year follow-up. Results: By Sanders classifications, there were 13 type II fractures (33.3%), 20 type III (51.3%), and 6 type IV fractures (15.4%). Average follow-up period was 35 months (range: 24~87 months) and at final follow-up of more than 2 years, Creighton-Nebraska score was average 76.0 (range: 30 ~ 100) which significantly improved from postoperative 1-year results of 67.1 (range: 22 ~ 95) (p<0.05). Conclusion: The clinical outcome at more than 2 years after surgical treatment of intra-articular calcaneal fractures was quite promising, which significantly improved compared to 1-year results. Therefore, we concluded that functional results of calcaneal fractures should be evaluated at least 2 years after the treatment.

목적: Y형 금속판을 이용한 상완골 과간 골절의 치료에 있어서 치료의 결과와 그에 영향을 미칠 수 있는 요인을 조사하였다. 대상 및 방법: Y-형 금속판을 이용하여 고정한 상완골 과간 골절 환자 중 1년 이상 추시가 가능하였던 17예를 대상으로 하였다. C1형이 9예, C2형이 4예, C3형이 4예였다. 11예에서 다른 부위의 동반 골절이 있었다. 평균 연령은 48.8세였으며, 평균 추시 기간은 33개월이었다. 평가는 Cassebaum 분류 (Cassebaum`s classification for elbow range of motion)와 Mayo Elbow Performance Score (MEPS)를 사용하였다. 결과: 주관절의 운동 범위는 평균 105도 (50∼150도)로 회복되었다. Cassebaum 분류에서 매우 우수 7예, 우수 1예, 보통 4예, 불량이 5예였으며, MEPS에서는 매우 우수 7예, 우수 7예, 보통 2예, 불량이 1예였다. MEPS상 보통 및 불량으로 평가된 3예 중 C3형이 2예였다. 수술 후 결과에 큰 영향을 미칠 만한 합병증은 없었다. 결론: 상완골 과간 골절에서 Y-형 금속판을 이용한 고정은, 환자의 선택이 적절히 이루어진다면 좋은 치료 방법이 될 수 있을 것으로 생각된다. 결과의 영향을 미치는 요인으로는 골절의 관절내 분쇄 정도라 생각되며 고 에너지 손상 여부 및 연령도 결과에 다소 영향을 미칠 것으로 생각된다. Purpose: To evaluate the results of the treatment of intercondylar fractures of the humerus using Y-plate. Materials and Methods: The subjects were 17 patients with intercondylar fracture of humerus who were treated using the Y-plate. Nine cases were C1 type, 4 were C2 type, and the remaining 4 were C3 type. 11 subjects had accompanying fractures of another part of the body. The average age was 48.8. The average follow up period was 33 months. We used Mayo Elbow Performance Score and Risborough-Radin`s rating score for each patient as the methods of rating. Results: The average range of motion of the elbow was 105 degrees (50∼150 degrees). According to Cassebaum`s classification for elbow range of motion, 7 cases were rated very good, 1 cases were good, 4 cases were fair, and 1 cases were poor. According to Mayo Elbow Performance Score, 7 were excellent, 7 were good, 2 fair, and 1 poor. Of the 3 patients who were fair or poor in Mayo Elbow Performance Score, 2 were type C3 fractures, and all 3 had major accompanying fractures. No significant postoperative complications developed in all cases. Conclusion: The fixation with Y-plate can still be a relatively good modality of treatment for interconylar fractures of the humerus in selected cases, in spite of the known mechanical weakness of the Y-plate. The patients with severe intra-articular comminution showed relatively poor results. And we think that the age of the patient and the energy of the injury have more or less influence on the results of treatment.

금형소재용 동합금의 미세조직 및 기계적 성질에 미치는 첨가원소의 영향

N/A Effects of Si and Ni addition on the microstructure and mechanical properties of the Cu-12wt.%Al-5wt.%Fe-1wt.%Mn alloy have been investigated experimentally. Microstructure of the as-cast specimen is found to be refined markedly by additions of Ni and Si. By the addition of Ni, volume fraction of the k phase is increased, but volume fraction of the y phase is decreased. Hardness is increased with the addition of Ni, due to increasing of k phase which is harder than y phase. However, Charpy impact value is not significally decreased possibly due to the formation of isolate k phase. (Received February 19, 1998)

The purpose of this work is to investigate .the effects of reduction ratios and temperature during hot rolling on the mechanical properties of Zr-Nb alloys. Based on the results of prior research work, Zr-1Nb-0.5Sn-0.5Mo-0.1Fe was selected as a basic alloy. The selected alloy was hot rolled with 25% and 50% reduction ratios at 700℃, 800 and 900℃. and microstructure, mechanical properties and texture were evaluated. From the results of DTA, it was found that β phase started to tranform into α phase at 960-950℃, and all the β phase transformed into α phase above 650-660℃. Also Kearns number, tensile strength and elongation increased with increasing reduction ratios of hot rolling. With increased hot rolling temperature, tensile strength increased. but elongation and Kearns number decreased.

Zr 계 합금의 기계적 성질과 재결정 온도에 미치는 Mo 의 영향

The purpose of this work is to investigate the effects of Mo content after cold rolling on the mechanical properties and recrystallization in Zr alloys. Based on the results of prior research work, Zr-1Nb-0.5Sn-xMo-0.1Fe was selected. The alloys were cold rolled with 50% reduction ratio. These alloys were recrystallized, after microstructure, mechanical properties and texture were evaluated. With increasing Mo content, Kearns number and the elongation decreased, but tensile strength increased. Also, with increasing Mo content, recrystallization temperature was retarded and grain size was refined. These facts were due to the effect of precipitation, solid solution of Molybdenum.

In the D-penicillamine induced myasthenia gravis, ptosis and diplopia may occur usually six to seven months after starting therapy. Muscular weakness is usually improved two to three months after discointinuing D-penicillamine without any treatment. The pathogenesis of drug induced myasthenia is not clear. The antiacetylcholine receptor antibody is noticed to be increased presumably due to altered immunological reactivity. The patient was a 52-year-old woman who had had rheumatoid arthritis for 5years. After four months of D-penicillamine therapy (500mg/day), she began to be suffered from diplopia and left ptosis. A tensilon test was positive. HLA DR1 was positive. Electromyographic finding was normal. No antibody to acetylcholine receptor was detected. Four months after cessation of D-penicillamine therapy symptoms and signs disappered without any treatment. We experienced a case of rhematoid arthritis with D-penicillamine induced myasthenia gravis in a 52-year-old female and report this with a review of literature.
