Endoscopic ACL reconstruction using bone-patellar tendon-bone has been considered the gold standard in the field of reconstructive ACL surgery. Technically, graft must be placed at isometric point. But it is difficult to evaluate the placement of graft postoperatively. The purpose of this study is to determine the radiological ideal position of graft by comparing postoperative results with the graft placement. Seventy cases of endoscopic ACL reconstruction were reviewed and classified according to the femoral and tibial graft position on radiologic imaging. The femoral graft position was classified in relation to angle of graft on anterior position view and distance from posterior margin of graft to the inner surface of posterior cortex on lateral view. The tibial graft position was classified in relation to intercondylar eminence on anterior posterior view and lateral view. Knee score (modified Marshall, Lysholum), manual anterior instability test (Lachman test, Pivot shift test) and arthrometer measurement were checked to evaluate postoperative results in each case. The results of this study implicate that knee joint in which femoral graft was oriented at direction of 11 o clock centring around 68 degree respect to tibial joint and placed within 3mm from posterior cortex showed higher knee score and lesser laxity. In cases of tibial side, the graft oriented to intercondylar eminence (AP view) and placed anterior to intercondylar eminence (lateral view) showed higher knee score and lesser laxity.

The authors reviewed serial chest films of 113 patients of spontaneous pneumothorax which were treated byclosed tube thoracotomy during the period from May, 1979 till July, 1982 in CNUH. The resuls are as follows; 1.Male was more frequently affected than female, and the sex ratio was 3.5:1. 2. 71.1 per cent of patients were over31 years of age. 3. Of the 113 cases, 51.3 per cent were on the right, 48.7 per cent on the left. 4. The mostcommon underlying pulmonary disease was pulmonary tuberculosis(39.8), the next was belb or bullar (17.7%), and thelast was pneumonia(8.8%). 5. Pneumothorax was the most common type in pulmonary tuberculosis(66.7%), andpyopneumothorax in pneumonia(80.0%). 6. Among 103 cases in complete re-expansion of collapsed lung after closedthe thoracotomy, 39.5 per cent was expanded completely within 1 week in presence of visceral and/or parietalpleural thickening, and 86.2 per cent in none of it. According to the degree of pneumothorax, the more severedegree of pneumothorax, the more delay in re-expansion times. 7. Most common chest finding after re-expansion ofcollapsed lung was pleural thickening(51.4%).

A relationship between preceding acute paralytic poliomyelitis and the later development of motor neuron disease has only occasionally been suggested since it was first postulated by Charcot in 1875. The authors recently experienced a 20-year-old male who was considered to have postpoliomyelitis muscular atrophy. We report this case in view of its rarity and necessity of differential diagnosis from other neuromuscular disorders. Clinical presentation included slowly progressive muscle wasting of left thigh for 4 years, mild weakness of left arm and both thigh, intermittent fasciculation, and previous history of acute paralytic poliomyelitis. Electromyographic findings showed fibrillation potentials, positive sharp waves, fasciculations, giant motor unit potentials and reduced interference patterns. Muscle biopsy revealed scattered small angulated fibers, individual myofiber degeneration and mild inflammatory cell infiltration.

BACKGROUND: To evaluate the changing pattern of liver abscess treatment, we did a retrospective analysis of 80 patients with liver abscess, treated surgically and medically at the Department of Surgery and Internal Medicine, Wonkwang University Hospital from January 1985 to December, 1995. RESULTS: Among 80cases of liver abscess, 59 cases(76%) were pyogenic abscess and 21 cases(24%) were amebic abscess. The liver abscess was more commonly located in the right lobe. In the 59cases of pyogenic liver abscess, etiologic factors were biliary stones with cholangitis(19 cases), cholecystitis(6 cases), hepatobiliary cancer(4 cases), diabetes mellitus(3 cases). All 21 cases of amebic abscess were treated with percutaneous catheter drainage and metronidazole administration; 20 cases were treated successfully and 1 case died of sepsis. Among the 59 cases of pyogenic liver abscess, 38 cases were treated with percutaneous catheter drainage; 30 cases were successful, but 8 cases were not. Operations were performed in 21 cases because of underlying intraabdominal conditions requiring surgical correction( 19cases) and panperitonitis due to rupture of liver abscess(2cases). CONCLUSION: In the treatment of amebic abscss, percutaneous catheter drainage and metanidazole adminstration should be considered first. Percutaneous catheter drainage and antibiotic treatment tend to increase more than surgical treatment in the pyogenic liver abscess therapy. The liver abscess is no more surgical indication, unless it is associated with underlying intraabdominal conditions requiring surgical correction and panperitonitis due to rupture of liver abscess.

The authors studied the diagnostic usefulness of the Topographic analysis of EEG, using Topography ststem 700 (San-ei), in evaluation of supratentorial focal cerebral lesions of 27 patients with various etiology, comparing with visual anslysis of EEG. Focal cerebral lesions, which were proven with brain C-T, were 11 cases of cerebral infarction, 6 of intracranial hematoma, 6 of cerebral gliolysis and 4 of others. The topography system displays the spatial distribution of activity in the classic delta, theta, alpha and beta frequency and computed mapping of EEG displays equipotential maps of square of roots of power spectra over each frequency band. For visual analysis of slow waves and background activity changes, Mayo classification system of EEG abnormality was used and for visual evaluation of topographic display, above system was also applied with some modification in order to compare with the data of visual analysis of conventional EEG. The results of the study were as follows; 1. While visual analysis of conventional anlysis of EEGs showed abnormality only in 13 cases (48.1%) of 27, topographic analysis showed abnormality in 22 cases (81.5%). Topographic analysis was more sensitive than than visual analysis of the EEG and topographic analysis was thought to be more sensitive in assessment of local slow waves as well as minor changes, especially slight asymmetry, of background EEG activity. 2. Topographic analysis showed higher concor dance rate (55.6%) to the brain C-T finding in lateralization of supratentorial focal cerbral lesion than that (44.4%) of visual analysis of the conventional EEG.

Gardner's syndrome is a familial disease consisting of gastrointestinal adenomatous polyposis, osteomas of the mandible, skull, and long bones, and a variety of sol tissue lesions, including sebaceous cysts, fibromas, lipomas, and desmoid tumors. The colon is the most common site for polyposis, but the stomach, duodenum, small bowel, and periampullary area may also be involved. The diagnostic evaluation, malignant potential, and management is identical to that for familial adenomatous polyposis. The extracolonic manifestations of Gardner's syndrome are frequent and varied. Gardner's syndrome is inherited as autosomal dominant traits. Authors experienced one case that is a 32 year old female patient who had colonic and duodenal multiple polyposis, desmoid tumor in abdominal wall and right mesocolon and odontoma on mandible.

The radiologic findings of lumbosacral spine and measurement of lumbosacral angle were analysed in 238 with backache and 102 without backache which were visited at Chungnam National University from March 1980 to July 1981.The measurement of lumbosacral angle was based on a method of Fergson. The results obtained were as follows; 1. The age group of 18 to 29 years was most common in backache group and the male was affected more frequently than the female with the ratio of 1.9 to 1. 2. In patients with backache, the overall mean lumbosacral angles were 44.2±2.6 degrees in male and 35.8±2.0 degrees in female. In patients without backache, in control group, the overall mean lumbosacral angles were 32.6±0.7 degrees in male and 33.4±1.4degrees in female. 3. In control group, difference of means between male and female was about 1degrees in patients with backache, the overall mean lumbosacral angles were increased about 12degrees in male and 2degrees in female than control group. In patients with and without backache, no significant difference of lumbosacral angle between the 4 age groups was present. 4. In backache group, increased lordosis was more common and increased lumbosacral angle than the decreased lordosis. 5. In backache group, lumbosacral angle of abnormal radiologic findings in lumbosacral spine was significantly increased than control group. 6. In patients with backache, radiologic findings and its lumboscral angles were alumbosacral anomaly 56 cases (23.5%): 46.9 degrees, increased lumbar lordosis 46 cases (19.2%): 48.1 degrees, osteoarthritis 44 cases(18.5%) : 40.8 degrees, decreased lumbar lordosis 30 cases (12.6%): 29.9 degrees, in order, And these radiologic findings were similar with many other authors.

Arthroscopic synovectomy has some limitations for adequate posterior visualization, and it is difficult to establish the posterior portal because of potential damage to neurovascular structures. The purpose of this study is to introduce a newly designed arthroscopic technique passing through posterior septum and to review the arthroscopic synovectomy using transposterior septal portal in the knee. Routine arthroscopic examination of the knee joint is performed using standard anterolateral and anteromedial portals. Posterior arthroscopic technique is divided into four steps. The first step is to make a posteromedial portal. The second step is to make a posterolateral portal. The third step is to make a hole at the posterior septum and to examine the posterolateral compartment. The fourth step is to examine the posteromedial compartment by switching the arthroscope to the posterolateral portal in the same manner. This technique provides complete visualization of the posterior compartment of the knee joint including the posterior aspect of the medial and lateral femoral condyles, posterior horn of both menisci, the posterior cruciate ligament(PCL), the meniscofemoral ligament, posterior aspect of the popliteal tendon, and the posterior capsule. We reviewed 47 cases(of 43 patients) of arthroscopic synovectomy using anterolateral, anteromedial and transposterior septal portal. The results were assessed with follow up of at least 1 year using the criteria of pain, synovitis, effusion, and range of motion. In 15 case rheumatoid arthritis, we had good result in 14 cases, but 1 case of recurrence was noted at 2 months after surgery. Non specific synovitis, 11 cases, had the similar result of rheumatoid arthritis. In 9 cases with hemophilic arthritis, pain and effusion were improved, but range of motion was improved minimally. In 2 cases with gouty arthritis, 2 cases with tuberculous arthritis, and I case with pigmented villonodular synovitis(PVNS), range of motion was rather reduced. It is considered that arthroscopic technique using transposterior septal portal is safe procedure without damaging the PCL, posterior capsule, neurovascular structures, and very efficient method in removing hypertrophied synovium or debris of persistent synovitis or arthritis of the knee joint and helpful in removing encapsulated loose bodies located behind the PCL.

The requirements of orthodontic wire should include chemical stability, non-discoloration and non-corrosion in oral environment. Ability to be soldered, ease of fabrication and elasticity should be also considered. The purpose of this study was to compare and analyze the physical properties of Tru-chrome. The results were as follows: 1. Tru-chrome wire and E.S.S. wire were SUS 304 which was 18 Cr-8Ni austenite stainless steel. There was not significant difference in each composition between two wires. 2. There were not significant differences in ultimate tensile strength, yield strength, elongation and modulus of elasticity between Tru-chrome and E.S.S. wires. 3. There was not significant difference between flexure modulus of elasticity of Tru-chrome and E.S.S. wires. 4. Micro-hardness value of E.S.S. wire was more than that of Tru-chrome wire and they were softened significantly by solution heat reatment. 5. Micro-structure of Tru-chrome and E.S.S, wires showed fibrous interlocking grains, and an austenite structure after solution heat treatment. 6. There was significant difference between corrosion rate of Tru-chrome and E.S.S wires.
