CT provides a valuable new perspective in assessing abnormalities of the thorax. In patients with amediastinal mass or widening detected by plain chest radiography, a definite diagnosis is sometimes possible whichwould not obtainable by conventional radiological technique. Clinical staging of bronchogenic carcinoma can beachieved by CT better than any other radiologic method. In fifty patients with histologically or angiographically confirmed disease of the thorax,an analysis of chest radiography and chest CT manifestations was made, and theresults were as follows; 1. 27 patients with mediastinal mass detected by chest radiography, a definite diagnosiswas possible in 10 patients (36%), who were 6 with teratodermoid, 1 with thymic cyst, 3 with aneurysm. In allpatients, the extent and localization of mediastinal mass could be established more precisely than by the chestradiography. 2. In 15 patients wtih bronchogenic carcinoma, 9 patients (60%) showed hilar adenopathy ormediastinal adenopathy which could not be noted on the chest radiography. 3. Main CT findings of braonchogeniccarcinoma were peripheral lung mass, spiculated or lobulated margin, adhesion to pleura or chest wall, andatelectasis or chronic pneumonia. 4. Commonly observed CT findings of teratodermoid were well capsulated mass,calcification, fat density , and multi-loculation. 5. Commonly observed CT findings of thymoma were homogenousmass, round contour, partially preserved mediastinal fat. CT was superior in evaluation of mediastinum and in the detemination of the extent of known bronchogenic carcinoma.

The major blood supply to the femoral head is probably damaged by the fracture of the femoral neck especially when it is a displaced fracture. Complications such as delayed or nonuion of the fracture and avascular necrosis of the femoral head are common. Revascularization after reduction and internal fixation appears to be a slow process and in many patients late segmental collapse occurs. Various techniques have been proposed to restore the blood supply or to improve the circulation to the femoral head. Hereby we performed internal fixation and an autogenous muscle-bone pedicle graft composed of the quadriceps femoris muscle in 3 cases of old, neglected displaced femoral neck fracture. The results seemed to be good in regard to bony union in all 3 cases but it would be needed further follow up study for developing of any avascular necrosis.

62 cases of the fracture of the pelvis admitted to the orthpedic department of Wonju Christian Hospital during past 5 years from 1975 to 1979 were reviewed and clinical results were obtained as follows: 1. Males were frequent than females and almost 3rd to 4th decades of life. 2. The causes of injury were traffic accident, coal minor accident, and falling. 3. Stable type is the most common in this series and among the unstable types, lateral compression type is the most common and then straddle type and vertical shear type. 4. The most common complication is uro-genital injury. 5. The residual complications at the end of treatment remained in some cases, Arthritis of sacroiliac joint, Impotence, Urethral stricture, Low back pain, etc. 6. All of the cases were treated conservatively and their results were somewhat good except 4 cases. 7. Surgical treatment would be considered, if necessory, to decrease the complications and reduce hospital days.

In the past, arthrodesjs was a widely used procedure but in recent times, with the development of replacement arthroplasty, decreased in tuberculosis and polio. etc, it is not commonly used by orthopedic surgeons. However, for those in the young age group, people employed in hard labor and patients with acute inflammatory disease, arthrodesis is through to be more appropriate than replacement arthroplasty. From January 1980 to December 1985, 20 cases of arthrodesis of the knee joint were carried out. The results were follows.; 1. Methods of arthrodesis used were Charnley compression arthrodesis in 10 cases, Hoffman compression arthrodesis in 2 cases, cross pinning in 3 cases and and cross pinning with patella graft in 5 cases. 2. Bone union was seen in all 12 cases of compression arthrodesis at an average of 21.3 weeks while bone union was seen in 7 out of 8 cases of non-compression arthrodesis at an average 25 weeks. 3. Among the 20 cases, complication were pseudoarthrthrosis in one case, pin tract infection in 2 cases and skin necrosis in 5 cases. 4. Inconclusion of the above results, bone union was carried out in 19 cases out of total 20 cases, and compression arthrodesis showed faster bone union at an average of 3.7 weeks earlier than non-compression arthrodesis.

The simultaneous occurrence of a renal cell carcinoma and a urothelial carcinoma in the same kidney is uncommon. Here we report the case of a 79-year-old woman with ipsilateral synchronous renal cell carcinoma and urothelial carcinoma. She was referred to our hospital for gross hematuria and right flank pain. A computed tomography scan showed a 15x20 mm enhanced lesion on the upper calyx and a 12x15 mm mass on the lateral aspect of the right kidney. We thus suspected a renal pelvis tumor and performed right hand assisted laparoscopic nephroureterectomy with bladder cuff excision (HALSNU). Gross findings were multiple, pale yellowish papillary masses on the upper and lower major calices, of which the largest one measured 16x20 mm. A separated solid mass measuring 12x16 mm was also noted on the anterior midportion of the kidney. The former was a urothelial carcinoma and the latter was a chromophobe renal cell carcinoma. We present a rare case of a chromophobe renal cell carcinoma and a urothelial carcinoma in the same kidney.

Clinical study was done on 119 patients with atrial fibrillation in the aspect of underlying diseases, particulary. The results were as follow : 1) In the underlying diseases of atrial finbrillation, rheumatic heart disease, hepertension and ischemic heart disease were common, which occupied 27.8%, 22.7% and and 15.1%, respectly. No apparent underlying disease was found in 21.0%, but in the transient atrial fibrillation, no apparent underlying disease in 42.9%. 2) There were no significant correlations between the ventricular rate, amplitude of f wave and underlying diseases of atrial fibrillation. 3) Complications were found in 29.4% of all cases, such as congestive heart failure(22.7%), embolism(6.7%). Otherwise, atrial fibrillation without underying cardiovascular diseases, congestive heart failure was found only(7.7%).

Recent development and advances in arthroscopic surgical techniques for Anterior Cruciate Ligament(ACL) reconstruction have led to the single-incision techniques. Several potential pitfalls in the classic single-incision techniques were found and it has become necessary to develop a new, simpler method to overcome these problems. Seventy-five cases of arthroscope-assisted ACL reconstruction were prospectively studied. The radiologic results were compared between the group in which femoral tunnel preparation was performed by the tibia tunnel(classic technique, 35 cases) and the group in which the anteromedial portal was employed(modified technique, 40 cases). Significantly better results were obtained at the angle formed by the bone graft and the interference screw, the angle between the femoral tunnel axis and the anatomic axis of the femur, and the angle between the femoral tunnel axis and tibial tunnel axis in the modified technique(P<0.05). This study presents a modified arthroscope-assisted ACL reconstruction technique that uses the anteromedial portal for femoral tunnel preparation and insertion of interference screw. In the modified ACL reconstruction technique, the femoral tunnel preparation and femoral graft fixation were accomplished in the same direction and the femoral tunnel preparation was performed regardless of the tibial tunnel preparation, this allows the surgeon to handle the arthroscope freely and advance more posteriorly to get a better view of the posterior cortex.
