Alveolar soft part sarcoma is a clinically and morphologically distinct soft tissue tumor that was first defined and named by Christopherson et al in 1952. Since 1953, alveolar soft part sarcoma invading bone have been reported sporadically. We experienced a case of alveolar soft part sarcoma with metastasis to femoral shaft, which was treated by wide resection & vascularized fibular strut graft.

Various kinds of spinal instruments have been developed for the treatment of lumbar spinal disordors. Recently, the Graf instrument as soft stabilizer has been introduced in treating lumbar spinal disordors associated with instability. To determine the reliability of Graf instrument providung spinal stability we have analysed 19 cases of unstable lumbar degenerative disease treated with adequate decompression and Graf instrumentation between May 1991 and March 1992. There were 15 females and 4 males. Average age at operation was 50.8 years (Range, 35 to 70). Minimum follow up was 14 months. The main surgical indication was serious limitation of daily activity caused by intractable symptoms and signs with spinal instability. Clinical assesment based on authors modified criteria revealed satisfactory (Exellent/Good) in 16 cases (84.2%). The Graf instrument has many advantages over rigid implant such as enough stability without arthrodesis after extensive surgical decompression, rapid rehabilitation, less operative risk and preservation of spinal motion. These results suggests Graf instrument instead of rigid implant is highly recommendable in managing unstable lumbar disordors.

Superficial gastritis has been classified as a type of chronic gastritis, since a report of Schindler in GASTRLTIS, 1947. Howev~er, Benedict reported that superficial gastritis is only acute gastritis or shows normal mucosa histologically. The com mon endopical findings of chronic superficial gastritis were adherent mucus, edema, redness. The common redness which were encounterd are patchy redness and comb-like redness(Kammrotung). We studied the relationship between the redness of superficial gastritis and acute inflammatory changes histologically. Each case of superfieial gastritis was biopsied to redening and non-redening mucosa respectively. We collected 24 cases with 48 biopsy specimens. The results are as follows: Acute inflammatory changes were found only one case in redness and none in non-redness groups. There was no difference in acute inflammatory changes in two groups. The degree of mucosal atrophy were 62.5%, 66.7% in normal mucosa, 12.5%, 16.7~% in mild atrophy, 25%, 12.5% in moderate atrophy, 0%, 4.l% in severe atrophy with respect to redness and non-redness mucosa respectively. There was no difference in degree of mucosal atrophy in two groups. Mucosal atrophies were higher in older ages above 41 years old than below 40 and with increasing age, there was increasing tendency of mucosal atrophy. In conclusion, There was no relationships between mucosal redness and acute in flammatory changes histologically and also between mucosal redness and degree of atrophy.

We report CT and MR findings in tow cases of primary malignant melanoma of the vagina, one arising from cervicovaginal junction mimicking squamous cell carcinoma of the cervix and the other one recurring at vagina after resection. Two cases of malignant melanoma had high-attenuation on CT and high signal intensity on T1-weighted MR images and enhanced well after gadopentetate dimeglumine administration.

The spinal fusion is used for correcting malformations, stabilizing unstable segments, and suppressing the progression of disease, but it causes more load on the adjacent segment and as a result, the degenerative changes accelerate. Furthermore, the accelerated changes case spinal stenosis, degradation of nucleus pulposus, degenerative spondylolisthesis, acquired isthmus defect, and arthritis of articular facet, it rarely needs surgical treatment. The purpose of this study is to know the effect of the fusion level and range on the adjacent segment, to be a standard for determining the fusion range prior to operation, and to help to find the complication like degenerative changes by measuring the range of motion on the adjacent segment after the spinal fusion. Authors analyzed the result of 29 cases of posterolateral lumbar spinal fusion which were operated from February 1989 and January 1994. The intervertebral angle was measured on the flexion and extension lateral radiographs, and the calculated angular motion and sagittal plane rotation at follow-up periods were compared with those of preoperative values. The results were as follows; 1. Among the adjacent segm0ent, the increment of angular motion of superior adjacent segment was 2.6°(-5°~15°) which was higher than that of inferior one with 1.5°(-3°~7°) 2. The increment of angular motion of superior adjacent segment for 1 segment rather than 2 or 3 segments was more than two times with 3.9°(-2°~15°) 3. Regardless of level and range of fusion, the increment of angular motion was 3.0°(-2°~8°) on 4.5th lumbar segment which was increased mostly and 1.5°(-3°~7°) on 5th lumbar and 1st sacral segment which was increased leastly. 4. There were 3 cases showed instability at the superior adjacent segment and no cases showed instability at the inferior adjacent segment among all the cases showing stability prior to operations. In conclusion, the sagittal plane rotation was increased in adjacent segment after posterolateral spine fusion. So, we would recommend that the adjacent segment is very important to the decision of fusion extent and level.

The medial collateral ligament(MCL) of the knee is the well established secondary restraint to the anterior displacement of the knee joint. However, there has been no report about the estimation of the anterior displacement in combined ACL(anterior collateral ligament) and MCL injures according to period when they were treated with conservative measures. This prospective study evaluated the changes of anterior displacement over time in combined ACL/MCL injury as the MCL injury heals after initial conservative measures. 19 patients who had combined ACL/MCL injury were followed during twelve months after injury. All patient had a positive Lachman test and were evaluated the side to side differences on KT-2000 knee arthrometer(Medmetric, San Diego, California) testing under 20 Ibs anterior tibial loading at 30 degree knee flexion. The stability of the knee was assessed using KT-2000 knee arthrometer every 8 weeks with clinical examination prospectively. They were treated with CI (Combined instability) brace (Smith & Nephew, Carlsbad, California) as conservative measures. Overall, Initial side to side difference of the anterior displacement was averaged 5.21mm (range,4.0-7.0mm) and 3.30mm (range,2.0-5.5mm) finally. According to the classification of MCL injury, in Grade III groups, they had the greatest initial anterior displacement about 6.4mm, but tight- ened the most to 3.08mm finally. In Grade II and Grade I groups they showed 2.97mm and 2.13mm side to side difference (p>0.01). However in Grade I, the anterior displacement were decreased by 4 months after injury but, it were increased at 6 months after injury. In Grade II and III, the decrement of the anterior displacement were continued by 6 months after injury, but they were not changed after that. The data was analyzed by General Linear Model Procedure method. Conclusively, the anterior displacement of knee in patients with combined ACL/MCL injury was diminished with the time in the majority of patients as the MCL healed. It means that the MCL was the stabilizer to the anterior displacement of the knee under the anterior tibial loading.
