Degenerative arthritis of the knee joint is one of the main causes of disability in middle-aged persons. This paper is planned by the necessity of objective information upon changes of tibio-femoral angle according to weight bearing in patients with degenerative arthritis of the knee joint. The authors studied the tibio-femoral angle in 29 cases of degenerative arthritis of the knee ranging fmm 5th to 6th decades of age, and compared with 27 cases of the control group, in the Dept. of Orthopedic Surgery, S.N.U.H. fmm Mar. 1983 to May 1984. The following observations were obtained: 1. In patients with degenerative arthritis of the knee, changes of the tibio-femoral angle according to weight bearing were +2.2±1.94 in 5th decade, +2.3±2.02 in 6th decade. 2. Compared to control group, the degenerative arthritis group showed a significant varization with weight bearing. 3. It was seemed that the weight bearing radiography is essential in diagnosis and treatment of degenerative arthritis of the knee joint.

PURPOSE: The differentiation between renal cell carcinoma(RCC) and transitional cell carcinoma(TCC) is important due to the different methods of treatment and prognosis. But occasionally it is difficult to draw a distinction between the two diseases when renal parenchyme and renal collecting systems are invaded simultaneously. MATERIAL AND METHOD: We reviewed CT scans of 37 cases of renal cell carcinoma and 12 cases of transitional cell carcinoma which showed involvement of renal parenchyma and renal sinus fat on CT. Retrospective analysis was performed by 3 abdominal radiologists. Check points were renalcontour bulging or reniform shape, location of mass center, intact parenchyme overlying the tumor, cystic change, calcification, LN metastasis, vessel invasion, and perirenal extention. RESULT:There were renal contour bulging due to the tumor mass in 33 out of 37 cases of renal cellcarcinima, wherea and nine of 12 cases of transitional cell carcinoma maintained the reniform appearance. This is significant statiscal difference between the two(p<0.005). Center of all TCCs were located in the renal sinus, and 24 out of 35 cases of RCC were located in the cortex(p<0.005). Thirty-six out of 37 cases of RCC lost the overlying parenchyma, whereas 4 out of 9 cases of well enhanced TCC had intact overlying parenchyma(p<0.005) RCC showed uptic change within the tumor mags in 31 cases which was significanity higher than the 4 cases in TCC(p<0.05). CONCLUSION: CT findings of renal cell carcinoma are contour bulging, peripheral location, obliteration of parenchyma, and cystic change. Findings of transitional cell carcinoma are reniform appearance, central location within the kidney, intact overlying parenchyma, and rare cystic change.

One may sometimes complicated with non-union of the tibia with intact fibula or comparatively early united fibular fracture during the cause of treatment of crural fractures. So that the fibula is to strut the tibial fragment preventing effective contact. Several authors have sporadically reported the removal of a portion of fibula may increase potential compression force across the tibial fracture site and promote bony union of non-delayed union of the tibia. Partial fibulectomy was performed in 9 patients with established nonunion of the tibia at National Medical Center from 1975 to 1982. The results were as follows: 1. Healing occurred in 8 of the 9 cases, and average time to union was 7.4months after fibulectomy. 2. In one case performed B-K amputation due to intractable infection after partial fibulectomy. 3. The average shortening of the involved lower limb was about 1.9cm. 4. All cases did not have significant symptoms at the fibulectomy site after union. 5. Partial fibulectomy proved to be a relatively effective method for the treatment of nonunion of the tibia.

The tibiofemoral angle is widely used for the diagnosis and treatment of knee problems, especially in degenerative joint disease of the knee. Among the various methods of measurement of tibiofemoral angle, Bauers method is being used most frequently. But measurement by Bauers method has seemed to show wide individual differences. Therefore we designed a ruler which can be used very easily for the measurement of the tibiofemoral angle with little differences between persons who measure the angle. To testify the advantages of our method, we selected 4 orthopedic surgeons and let them measure the tibiofemoral angles of 60 knees of 30 patients by Bauers method and by our method using the ruler. And 20 orthopedic surgeons measured tibiofemoval angles of 2 left knees by Bauers method and by our method using the ruler. The values of the tibiofemoral angle by two methods were compared and analyzed statistically. There was no significant differences between mean values. But, the tibiofemoral angles by our new method showed little differences among measurers. (P < 0.05)

The menisci or semilunar cartilages of the knee provide the function of mechanical lubrication and they are particularly important in allowing rotational movements of the knee joint. The study was carried out on 123 Korean adult knees for measurement of the menisci and observation of surrounding ligamentous structures through anatomical dissection of formalin embalmed cadavers. Detection of abnormal meniscal lesions was also included in this study. The following results were obtained: 1. A-P diameter, transverse diameter, maximal width and thickness were measured in 123 knees of 62 cadavers. 2. Among 62 cadavers,' the anterior menisco-femoral ligament was present in 11 subjects (17.7%), the posterior menisco-femoral ligament in 59 (95.2%), and the transverse ligament in 36 (58.0%). 3. Discoid lateral meniscus was found in 5 knees (4.1%), and tear was associated in 3 of them. 4. Meniscus tear was found in 13 knees (10.6%), and the site of tear was medial in 9 knees and lateral in 4 including 3 torn discoid menisci. The oblique pattern of tear was most common.

Most loci associated with type 2 diabetes mellitus (T2DM) discovered to date are within noncoding regions of unknown functional significance. By contrast, exonic regions have advantages for biological interpretation.

The bone mineral densities of 60 middle school boys were measured with dual photon absorptiometry to define the influence of Taekwon-Do. They were divided into Taekwon-Do and control group, each comprising 30 boys. The bone mineral densities of the head, trunk, pelvis, both upper and lower extremities, and body total were measured. The results were as follows. 1. The BMD of head was 1.668 ± 0.153 in Taekwon-Do and 1.554 ± 0.153 0.167 in control. It was significantly increased in aekwon-Do(p <0.05). 2. The BMD of trunk was 0.378 ± 0.153 0.044 in Taekwon-Do and 0.353 ± 0.153 0.053 in control. There was no significant difference(p >0.05). 3. The BMD of pelvis was 1.648 ± 0.153 0.112 in Taekwon-Do and 1.444 ± 0.153 0.215 in control. It was significantly increased in Taekwon-Do(p <0.005). 4. The BMD of right and left legs were 1.597 ± 0.153 0.118 and 1.579 ± 0.153 0.125 in Taekwon-Do and 1.425 ± 0.153 0.115 and 1.421 ± 0.153 0.113 in control group respectively. They were significantly increased in Taekwon-Do(p <0.005). 5. The BMD of right and left arms were 1.184 ± 0.153 0.090 and 1.178 ± 0.153 0.115 in Taekwon-Do and 1.056 ± 0.153 0.095 and 1.066 ± 0.153 0.097 in control group respectively. They were significantly increased in Taekwon-Do(p.<0.005). 6. The total body BMD was 0.932 ± 0.153 0.068 in Taekwon-Do and 0.846 ± 0.065 in control. It is significantly increased in Taekwon-Do(p<0.005). In conclusion, Taekwon-Do increases the total bone mineral density and the mineral densities of the head, pelvis and extremities but not that of trunk. It is thought that continued practice of Taekwon-Do throughout adult life might prevent the senile osteoporosis
