Toward the beginning of the twenty-first century, the world experiences the dramatic changes in politics, economics and culture, and it is evident that the Korean medical field will not be able to survive provided it doesn't prepare ourselves to adapt to those changes. The Korean Medical Society held a forum for the active operation of the medical society, inviting several leading affiliated societies, to meet the needs of the times. This review describes the summary of the presentation that the authors made on behalf of the Korean Radiological Society in the forum, including the organization, current status of academic activity, current status of international communication, and problems encountered in the internationalization of the Korean Radiological Society.

Specific bone signal abnormalities of MRI of patient with knee injury, although plain radiographs are normal, suggest that ACL injury may be present. Twenty eight MRI examinations in which ACL injury were present, were retrospectively reviewed and were correlated with bone signal changes. The results obtained were as follows; 1. Of twenty eight ACL injuries seen with MR imaging, bone signal abnormality was present at the lateral femoral condyle (LFC) in 8 patients (29%), at the posterolateral tibial plateau in 10patients (36%) and at both sites in 5 patients (18%). 2. In acute knee injury, all seven patients with complete ACL tear had bone signal abnormalities at MRI and of all seven patients, six patients showed bone signal abnormalities at lateral femoral condylar or posterolateral tibial plateau. 3. In conclusion, bone signal abnormalities at posterolateral tibia or lateral femoral condyle are present in almost cases of acute complete ACL tear. Therefore the bone signal abnormalities suggest that there may be ACL injury.

Radilogic findings in 30 patients with intestinal tubeculosis and 10 patients with intestinal Behcet'sdiseases, who had been diagnosed at seoul National University Hospital during the recent 5 years, were analysedretrospectively to evaluate the radiologic differential diagnosis of the two diseases. Intestinal tuberculosisseverely involved the cecum, the ileocecal valve, the distal ileum and colons, but Behcet's disease mainlyinvolved th distal ileum and infrequently the ileocecal valve and the cecum. The ulcers in tuberculosis wereusually multiple small barium collected areas among psuedopolyps on the contrary, those in Behcet's disease weremultiple, discrete, well marginated, geographic, ring-like deep penetrating or collar-button shaped. Intestinaltuberculosis tended to involved long segments of intestines, with severer mucosal irregularity and deformity ofthe ileocecal valve and the ascending colon in comparison with Behcet's disease. Mesenteric and/or peritonealinvolvment were accompanied in 1/3 cases of intestinal tuberculosis,a nd active pulmonary tuberculosis or pleuraleffusion also in 1/3 cases of intestinal tuberculosis.

Differential diagnosis of vertebral lesion by simple radiography is not so easy whether the lesion is benign or malignant. The purpose of this study is to evaluate that the magnetic resonance imaging characteristics can differentiate benign or malignant vertebral lesions. In this study, thirty-nine cases of signal change within the vertebral body by MRI was reviewed retrospectively and the followings are the summary of the results. It is difficult to differenciate benign or malignant lesions, only based on MRI signal changes or vertebral lesion patterns. But those cases of pedicle involvement, complete replacement of bone marrow in T1image and associated soft tissue mass or cord compression are strongly suggest the possibility of malignancy and need further study.

The carpal tunnel syndroms is the most common peripheral nerve entrapment syndrome. The typical symptom is pain, numbness and paresthesia in the median nerve territory of the hand and progressive thenar atrophy. When the symptom is mild and its duration is short, conservative treatment such as splinting or local steroid injection is considered, but when neurological deficit is promiment and conservative treatment is not effective, surgical decompression is indicated.Authors reviewed 15 patients (23 cases) of carpal tunnel syndrome treated with surgical decomression at the Department of Orthopedic Surgery, Kyung-pook National University Hospital from March 1983 to October 1988. The follow up results are as follows; 1. Preoperatively, Tinel sign was present in 17 cases. Phalen test was positive in 17 cases. Sensory disturbance was present in 8 cases. Thenar muscle atrophy was present in 19 cases. Motor weakness was present in 13 cases. 2. Preoperatively, delay of motor conduction velocity of median nerve was noted in 15 cases (65.2%) and sensory nerve conduction velocity in 20 cases (86.9%). Denervation findings such as fibrillation or sharp waves were seen in 15 cases (65.2%). 3. The operative findings were as follows; Synovial hypertrophy in 12 cases, hypertrophy of transcarpal ligament in 4 cases, pseudoneuroma in 3 cases, ganglion in 2 cases, neurilemmoma in 1 case, gout in 1 case. 4. As the operative findings, median nerve had evidence of compression beneath the transcarpal ligament, consisting of flattening. narrowing and decreased epineurial vascularity. 5. External neurolysis was performed in all cases. 6. In case of long duration and severe thenar atrophy, internal neurolysis would be recommendable. 7. Fllow up period was ranged from 7 months to 6 years. 8. 19 cases (82.6%) were excellent or good results.

To compare the results of the chemonucleolysis and the automated percutaneous lumbar discectomy(APLD) for symptomatic lumbar disc herniation, retrospective study of 19 chemonucleolysis and 20 APLD was done from July, 1984 to February, 1993. Number of male patients was 23 and female 16. The patients ranged in age from 14 to 56 years. L4-5 was the most commonly involved level comprising 73.6%, and 2 level involvement was 20.5%. Clinical results were evaluated according to Mcnab s criteria. Excellent and Good result were 31.6% and 47.3% in chemonucleolysis with an average follow up period of 6.2 years, and those were 35% and 45% respectively in APLD with an average follow up period of 18.7 months. Among 19 chemonucleolysis, there were loss of disc height in 8, and lateral recess stenosis in 1. Among 20 APLD, there were loss of disc height in 2, and nerve root irritation symptoms in 2. Chemonucleolysis and APLD have a low morbidity, can be performed under the local anesthesia and are simple, rapid and less traumatic procedure.

Flexor tendon grafting is a well-proved procedure for the restoration of tendon defects in the hand. The results are not entirely predictable, it offers a good expectation of successful outcome. Authors have performed the tendon graft in thirteen cases of flexor tendon injury of the hand during the period from September '79 to January '82 and evaluated the results. The followings were the results obtained. 1. Male was eleven, female was two. Age distribution is from 4 to 38 years. 2. Injured fingers were thumb 6, index 2, middle finger 4 and little finger 1 cases. The site of the primary injury was on area of Bunnell's Zone II in all cases. 3. Time interval from tendon injury to flexor tendon graft was 6 weeks to 19 months (average 5.6 months). 4. The results of tendon grafts rated as excellent 2 cases and good 3 cases in preoperative Good group; excellent 1, good 3 and fair 1 in “Scar” group; fair 1 and 1 poor in “Joint” group; fair 1 in “Salvage” group. In the thumbs, the results were better than in the fingers. 5. Degrading the postoperative results were flexion contracture in 3 cases, lack of flexion ROM in 2 cases and bowstringing in 2 cases. 6. Pinch power of the finger where tendon graft was performed was 52% of that of the opposite healthy finger. 7. As complication, bowstringing was observed in 2 cases and recurvatum deformity of the PIP joint in one case.
