PURPOSE: To evaluate the surface anatomy of the central sulcus(CS), precentral gyrus(PrCG) and postcentral gyrus(PoCG) on the basis of sulci pattern on MR images. MATERIALS AND METHODS: The MR images were obtained in the plane 10 degree angled to the orbitomeatal line. The MR images of 120 subjects(6 months to 79 years) with normal anatomy were analyzed and another four subjects with known space occupying lesions were also reviewed. RESULTS: The identification of gyri was feasible on the axial T1WI from anterior to posterior and from upper to lower images. The STS demonstrated symmetric pattern on both sides in 84 of 120 cases (70%), including two cases of prominent STS pattern. The asymmetric pattern was seen in 36 of 120 cases (30%):14 of 120 cases (12%) on the right and 22 of 120 cases (18%) on the left at 4.5 cm above the level of the splenium of corpus callosum. The PrCG and PoCG and CS were identified well in all cases with the use 'of the sulci pattern. CONCLUSION: The identification of the gyri on the basis of the cerebral sulci pattern on MR images is useful and important when locating the space occupying lesion of the brain.

The purpose of this study is to evaluate the results of bone graft or cement fill for tibial bone defect in total knee arthroplasty. 51 knee in 45 patients which had bone graft or cement fill for tibial bone defect of more than 1cm3 in total knee arthroplasty, between March, 1990 and July, 1994 at the department of Orthopedic Surgery in Hanyang University Hospital were followed for average 30 months. Bone grafts were performed in 33 knees and cement fills in 18 knees. The size of tibial defect was measured after removal of sclerotic and dense bone in the tibial plateau. The average size of tibial defect treated by bone graft was 4.9 cm3 in volume, 11 mm in height and the average size of tibial defects treated by cement fills was 1.5cm3 in volume, 6.8 mm in height. The results were as follows ; 1. In true A-P and lateral x-ray checked by fluoroscopic guide, trabecular union was seen in all 33 knees of bone grafts without collapse, loosening and bone resorption. In one of 18 knees of cement fill, radiolucent line was detected 2 mm in width between cement mantle and the adjacent tibial bone. In other 17 knees, radiolucent was seen 1 mm or less in width. 2. According to the system of Knee Society Score, average knee rating score was improved from 23.2 points preoperatively to 90 points postoperatively in bone graft cases, from 23.4 points preoperatively to 93.2 points postoperatively in cement fill cases. Average functional score was improved from 14.8 points preoperatively to 81.5 points postoperatively in bone graft cases, from 13.3 points preoperatively to 81.4 points postoperatively in cement fill cases. 3. Finally, we obtained the good results by cement fill during cement fixation of tibial component or bone graft without cement fixation of tibial component for small tibial bone defect and by bone graft for large tibial bone defect.

Fifteen women with symptomatic uterine myomas, diagnosed by clinical examination and confirmed by pelvic ultrasonography, were treated with intranasal insufflation of Nafarelin acetate, 200 micrograms, twice a day, for a total treatment period of 6 months. Treatment was evaluated with respect to subjective symptoms, changes in myoma size and uterine volume, variations in blood estradiol, FSH, LH and CA 125, and side effects. The following results were obtained: 1. All patients showed a marked reduction(p<0.001) in uterine volume. Before treatment volume measured 312.3+/-24.2cm3, after 12 weeks volume was 132.4+/-40.6cm3, and after 24 weeks it was 123.6+/-48.3cm3. 2. Blood estradiol and LH levels were decreased significantly(p<0.05) after treatment. The FSH level was decreased, but not significantly. 3. Blood CA 125 levels were increased 6 cases(40.0%) before treatment. The levels were normalized in all 6 cases after treatment. 4. Symptoms of uterine myoma disappeared or decreased. 5. Minor side effects, such as hot flushes, headache, general myalgia and fatigue, and vaginal dryness were encountered frequently although none necessitating discontinuation of treatment, These data suggest that Nafarelin acetate is useful for the treatment of uterine myoma. However, appropriate indications should be selected in the treatment of uterine myoma because the possible regrowth of uterine myoma after treatment limits the use of GnRH agonist.

Fifteen patients with 38 compression fractures of the spine underwent magnetic resonance(MR) imaging. We retrospectively evaluated MR images in these benign compression fractures. MR images showed four patterns in T1-weighted images. MR imaging patterns were normal signal(21), band like low signal(8), low signal with preservation of peripheral portion of the body(8), and diffuse low signal through the vertebral body(1). The low signal portions were changed to high signal intensities in T2-weighted images. In 7 of 15 patients(11 compression fractures). There was a history of trauma, and the remaining 8 patients(27 compression fractures) had no history of trauma. Benign compression fractures of trauma, remained 8 patients(27 compression fractures) were non-traumatic. Benign compression fractures of the spine reveal variable signal intensities in MR imagings. These patterns of benign compression fractures may be useful in interpretation of MR imagings of the spine.

PURPOSE: This study compared the accuracy of an abutment-framework (A-F) taken with open tray impression technique combining cementon crown abutments, a metal framework and resin cement to closed tray and resin-splinted open tray impression techniques for the 3-implant definitive casts. The effect of angulation on the accuracy of these 3 techniques was also evaluated. MATERIAL AND METHODS: Three definitive casts, each with 3 linearly positioned implant analogs at relative angulations 0, 30, and 40 degrees, were fabricated with passively fitted corresponding reference frameworks. Ten impressions were made and poured, using each of the 3 techniques on each of the 3 definitive casts. To record the vertical gap between reference frameworks and analogs in duplicate casts, a light microscope with image processing was used. Data were analyzed by two-way analysis of variance and the Tukey test. RESULTS: The open tray techniques showed significantly smaller vertical gaps compare to closed tray technique (P < .05). The closed tray and the resin-splinted open tray technique showed significantly different vertical gaps according to the angulation of implant (P < .05), but the A-F impression technique did not (P > .05). CONCLUSION: The accuracy of the A-F impression technique was superior to that of conventional techniques, and was not affected by the angulation of the implants.
