The authors have studied 60 cases of back pain with respect to diagnostic accuracy of myelography with metrizamide from January, 1983 to Decembar, 1984 at the Department of Orthopaedic Surgery, College of Medicine, Kyung Hee University. The results were as followes; 1. Of the 60 cases, 57 cases (95%) showed excellent and good findings of myelography. 2. In case of the marginal clearance of the nerve-sleeve in myelography, the excellent finding was 93.3%.3. The side effect of myelography was slight and 44% of all patients complained of headache, which disappeared within 24 hours after onset in 92% of them. 4. The accuracy rate of myelography with metrizamide was 89. 2%.

Tuberous sclerosis is a complex neurocutaneous disease inherited as an autosomal dominant pattern, which is characterized by facial angio-fibroma, mental retardation and seizures. Many cases have been reported in the literatures, but familial cases are relatively rare. We present 9 cases of tuberous sclerois occuring througb 3 generations, which are 3 cases of angiofibroma, mental retardation and seizures, 2 cases of facial angiofibroma and seizures, 1 case of mental retardation and seizures and 3 cases who showed facial angiofibroma only. Two brothers in this family reveald icthyosis vulgaris without tuberous sclerosis.

Osteosarcoma is the most common primary malignant tumor in the orthopaedic field. Recently, the management of osteosarcoma was evolved in many aspects and the improved results were reported in many articles. The purpose of this study is to evaluate the changes of clinical findings and management modalities in osteosarcoma since 1980. We reviewed 127 osteosarcomas managed from 1980 to 1992. The Enneking surgical stage was as follows; stage I 12 cases, stage II 98 cases and stage III 17 cases. They were subclassified into classic(97 cases), parosteal(12 cases), telangiectatic(5 cases), secondary(4 cases), periosteal(2 cases), gnathic(2 cases), high grade surface(1 cases) and undetermined(4 cases). The disease-free survival rate was evaluated for the patients of stage II classic osteosarcomas treated with amputation(27 cases) or limb-salvage operation(23 cases), and average follow up period of them was 49 months. In 27 cases of amputation adjuvant chemotherapy was administered in 23 cases. And in 23 patients treated with limb-salvage operation, neoadjuvant and adjuvant chemotherapy were done in 19 cases and only adjuvant chemotherapy in 2 cases. The clinical changes since 1980 were as follows: (1) The mean duration from symptom onset to diagnosis was decreased gradually from 6.5 months(1980) to 3.1 months(1992). (2) The proportion of curative surgery was increased from 40%(1980) to 87%(1992) in stage I and II. (3) The proportion of limb-salvage operation was rapidly increased upto 88% since 1985. The 5 year disease-free survival rate of stage II classic osteosarcoma was 36% with amputation and 67% with limb-salvage operation.

The posterior cruciate ligament is the primary static restraint to posterior translation of the tibia and provides proprioception within the knee. The goals of treatment in the injuries of PCL are restoration of normal tibiofemoral stability and reduction of long term osteoarthrosis of the knee. The purpose of this study is to cornpare functional outcome, muscle power, and posterior stability between conservative treatment and reconstruction with autogenous RPTB augmented with Kennedy LAD in PCL injuries. Twenty-seven patients with PCL rupture who have been treated from November 1990 to May 1996 were reviewed. The patiens were divided into conservative group and reconstruction group. Conservative treatment was done in 15 patients and reconstruction by autogenous bone patellar tendon bone with Kennedy LAD was performed in 12 patients. All patients were evaluated with posterior stress x-ray films, KT-2000 knee ligament arthrometer, Cybex 340 isokinetic dynamometer, subjective Cincinnati symptom rating scale and Lysholm knee score, complication. The results were as follows; 1. Mild and moderate posterior instability was remained in spite of BPTB graft and need more stable fixation technique and vigorous rehabilitation program. 2. At the angular velocity of 90 degree/sec and 180 degree/sec, the muscle strenth of quadriceps was decreased after PCL injury in both group in the test of Cybex 340 isokinetic exercises. The power of hamstrings were not changed after PCL injuries. 3. Average Lysholm knee score was 89 points in reconstruction group and 78 points in conservative group and average Cincinnati symptom-rating scale was 8.4 points in reconstruction group and 7.1 points in conservative group. More satisfied functional results and subjective symptoms were revealed in the reconstruction group and statiscal significancy (p<0.05) was showed when comparing conservative group with reconstruction poup. 4. Good clinical results did not always coincidence with lesser posterior instability and clinical results were influenced by associated injury of the knee. The more combined ligament injury of the knee, the worse clinical results.

Takayasu,s arteritis is a systemic disease characterized by occlusion of aorta and its major branches because of a panaortitis with thickening of the adventitia. Coronary artery narrowing is due to extension of inflammations that occur in aorta. Angina pectoris may be the first symptom of the disease if the coronary arteries are the initial site of severe arterial narrowing. We present a case of bilateral coronary ostial stenosis where Takayasu,s arteritis was pathologically proved as an etiology. The patient was taken coronary ostial angioplasty with good result.

In the 88 cases of biliary disease, which was proven in Seoul Red Cross Hospital from Jan. 1980 to Dec. 1981,comparative studies were made with oral and IV cholecystocholangiographic findings and ultrasonographic findings.The resuslts were ; 1. In the 18 cases of GB stones, there are 17 cases (94.4%) of positive findings incholecysto-cholangiography with detection of stone in 7 cases (38.9%), while in sonographic study, 16 cases(88.9%) are shown positive findings with detection of stones in 11 cases (61.1%). 2. In the 17 cases of acalculouscholecystitis, the diagnostic accuracy is 88.2% in cholecystocholangiography and 64.7% in sonography. 3. In the 7cases of CBD stones, all cases are shown positive findings in cholecystocholangiography with detection of stone inonly one case (14.3%), while 6 cases (85.7%) of positive findings are shown in sonography with detection stone inall cases. 4. I.V. cholanagiography is more accurate diagnsotic procedure rather than oral GB study in the casesof poor or non-functioning GB. 5. Sonography is the choice of procedure in the diagnosis of stones, while in thecases of colecystitis, cholecystocholangiography is more useful diagnostic procedure.
