The management of supracondylar fractures of the femur remains controversial. Most studies over the past twenty years have attempted to compare the results of non-surgical with those of surgical methods. Until a few years ago, conservative treatment was considered superior to internal fixation of supracondylar fractures of the femur. However, the development of new fixation devices and techniques have, according to several investigations, improved the results of the treatment of these fractures. The following clinical results were shown by analysis of 96 cases of supracondylar fractures of the femur treated in the Department of Orthopedic Surgery, Yonsei University, College of Medicine during the past 10 years from Jan. 1971 to Dec. 1980. 1. The prevalent age distribution was between 21 and 50 years of age (79.1%), and the ratio between males and females was 3.4:1. The most common cause of injury was car accidents (51.0%). 2. A classification of supracondylar fractures was unicondylar, simple supracondylar and intercondylar. Intercondylar which was subdivided into Type I, II-A, II-B, III according to Neer's classification. 3. Fifty nine patients (61.4%) were associated with injuries of other parts and the most frequent associated fracture was tibial fracture and the most common associated soft tissue injury was cerebral concussion or contusion. 4. The methods of treatment: conservative management by using skeletal traction for 34 cases, surgical treatment by open reduction and internal fixation for 58 cases and A-K amputation for 4 cases due to populiteral artery injury. 5. Fifty nine cases were suitable for result analysis. The satisfactory result of surgical treatment was 63.4% and conservative treatment was 50.0% respectively. The factors affecting the final results were Type of fracture, severity of injury, and rigid internal fixation. 6. The main complications of the supracondylar fractures of the femur were delayed union (10.2%), infection (10.2%), and traumatic arthritis (13.3%). 7. Finally, the results of treatment depend largely on anatomical reduction, rigid fixation, early joint motion.

Two cases of ureteral fibrous polyp showing serpiginous filling defect on IVP are presented with characteristic radiologic features; easy flow of contrast medium around polyp. Prolapsed polyp in urinary bladder, and less ureteral obstruction or renal damage than in epithelial lesions. These rediologic findings enable to differentiation of ureteral fibrous polyps from malignant tumor, which is helpful for determining therapeutic approach.

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.

PURPOSE: To evaluate the pattern of distant lymph node metastasis in colorectal carcinoma and its correlation with distant organ metastasis. MATERIALS AND METHODS: We retrospectively reviewed abdominal CT scans of 46 patients with pathologically proven colorectal carcinoma. RESULTS: The incidence of distant lymphadenopathy in colorectal carcinoma was 30.4%(14/46). The most commonly involved distant lymph node was the left paraortic lymph node below the renal hilum(9/25). The most common type of distant lymphadenopathy was solitary type(7/14) and all of these lymphadenopathies were noted in the left paraortic lymph node below the renal hilum. Six cases of left sided colorectal carcinoma showed left paraortic lymphadenopathy with solitary type. The incidence of distant organ metastasis was 17. 4%(8/46) and markedly increased if distant lymphadenopathy was multiple and confluent, or confluent type(5/7). CONCLUSION: The incidence of distant lymphadenopathy in colorectal carcinoma was not high and the most common lymphadenopathy was the left paraaortic lymph node with solitary type below the renal hilum. The possibility of distant organ metastasis was high if distant lymphadenopathy was multiple and confluent, or confluent type.

On 2,372 ophthalmic patients that received ocular examination and treatment by the author's medical service intended for doctor less farming and island villages, analyses were done according to disease entity, age, sex and district. The results were as follows: 1. Of the 2,372 patients, male was 384 (25.4%) and female 1,129 (74.6% and total 1,513 in farming districts, male 356 (41.4%) and female 503 (58.6%) and total 859 in island districts. Female far outnumbered male. 2. The most common ocular disease is pterygium (458 of 1,513, 30.3%) in farming districts and chronic catarrhal conjunctivitis (249 of 859, 29.0%) in island districts. 3. Of the pterygium patients, male was 77 (16.8%) and female 381 (83.2%) of 458 (30.3%) in farming districts, male 37 (30.3%) and female 85 (69.7%) of 122 (14.2%) in island districts. There was predominantly high incidence in farming districts, female and the age groups of the fifth and sixth decade. 4. In the nasolaorimal duct obstruction patients, male was 16(17.2%) and female 77(82.8%) of 93 (6.1%) in farming districts, male 12 (27.3%) and female 32 (72.7%) of 44 (5.l%) in island districts. There was no significant difference of the incidence in both districts, but mostly they were female and the age group from the fifth to seventh decade. 5. Of the cataract patients, male was 20 (24.7%) and female 61 (75.3%) of 81 (5.4%) in farming districts, male 10 (38.5%) and female 16 (61.5%) of 26 (3.0%) in island districts. There showed significant high incidence over age 50. 6. In the glaucoma patients, male was 3 (33.3%) and female 6 (66.7%) of 9 (0.6%) in farming districts, male 2 (40.0%) and female 3 (60.0%) of 5 (0.6%) in island districts. 7. Of the trachoma patients, male was 2 (28.6%) and female 5 (71.4%) of 7 (0.5%) in farming districts, male 24 (42.9%) and female 32 (57.1%) of 56 (6.5%) in island districts. Island districts and female were more predominant. 8. Of the 694 cases that required operation, only 287 (41.4%) received surgical procedures and on concerning to pterygium which was the majority, operations were done in 208 (35.9%) of cases.

The CT digital radiography is a new accurate technique for measuring the long bone length. Authors performed acomparative study on accuracy, time and film consumption and radiation dose between conventional spot scanogramand CT scanogram. We used two femur and two tibia specimen for materials, the Somatom II(Siemens) for CTscanogram, and Rad Check(Voctoreen) for radiation dosimetery. There was no significant difference in accuracybetween direct measurement, conventional scanogram and CT scanogram(lesser than 1% difference). The examinationtime of conventional scanogram was about 35 minutes, CT was 15 minutes, and the film consumption of spot scanogramwas 3 of 14x17'' size, but the CT scanogram need only one 8x10'' film for completion of study. The radiation doseof hip, knee and ankle joint were 220 mRad, 365 mRad, respectively, in spot scanogram, but it was lesser than 5mRad in all joints in CT scanogram. The advantages of the CT scanogram are simple, rapid and reduced radiation.
