The disc internal disruption syndrome is not well known to us, but the following hypothesis is widely accepted in clinical practice. The disc internal disruption syndrome may develop intractable back pain with aggravated of pain, loss of spinal motion with any physical exercise, leg pain, loss of energy, marked weight loss, and profound depression. The patient with this syndrome will be found to have normal plain roentgenograms, myelograms, CT scans, results of blood examination and neurologic findings. For these reasons, this syndrome was frequently diagnosed by abnormal discographic findings. We had experience with two cases of disc internal disruption syndrome with clinical, roentgenographic and discographic evaluations. Thus we present these case with a brief review of the concerned literature.

PURPOSE: To evaluate the clinical outcome and reliability of mixed bone in the process of posterior spinal fusion for the treatment of thoracolumbar spine fractures. In order to eliminate donor site morbidity which is linked to the use of autogenous bone graft, a new surgical procedure mixing autogenous bone chips that were obtained from local decortication of the posterior element of the spine with highly purified calf bone (Lubboc) is studied. MATERIALS AND METHODS: We followed up 9 patients who had undergone autogenous bone graft and 9 patients who had undergone mixed bone graft for more than 12 months out of 33 patients who underwent posterior spinal fusion for thoracolumbar spine fractures between July 1993 and July 1997. RESULTS: Radiographic results indicated solid bony union in 17 of 18 cases regardless of the graft materials. Based on each follow-up evaluation, it was found that the increase in kyphotic angle was related to elapsed time rather than to the type of graft materials. CONCLUSIONS: It appears that the new surgical method of bone graft with highly purified calf bone can be a reliable alternative for achieving stable posterior spinal fusion as long as bone chips large enough to fill the interlamina space can be obtained.

6.The Role of Endorectal Ultrasonography in the Follow-up Evaluation of the Uterine Cervical Carcinomas in Intra-arterial Cisplatin Chemotherapy.
Journal of the Korean Radiological Society 1994;30(6):1135-1140
PURPOSE: lntra-arterial cisplatin infusion chemotherapy delivers higher concentration of this therapeutic agent to the limited area of cervical carcinoma. We evaluated the role of endorectal ultrasonography (ERUS) in the analysis of the tumor response to this chemotherapy. MATERIALS AND METHODS: ERUS was done in 20 patients of cervical carcinomas limited to the pelvis by rotating the 5 UHz linear arraytransducer along the reference sagittal plane in the middle of uterine cervix and vagina. We examined and compared the change of tumor size and morphology on ER US, before, during and after intra-arterial cisplatin (50 mg/m2) chemotherapy through internal lilac artery near uterine arterial branching. Colposcopy and radical hysterectomy with pelvic lymphadenectomy were performed in all patients, and ERUS findingswere compared with those findings. RESULTS: ERUS correlated well with surgery in the estimation of preoperative tumor size and morphology. Tumor reduction rate on ERUS (100-the largest area of the preoperative tumor/the largest area of the initial tumor) was as follows: more than 75% decrease of the original size in 3 patients, 75% -50% in 6 patients, 50%-25% in 8 patients, and less than 25% in 3 patients. Hyperechoic reflecting areas were noted in 4 patients, which corresponded to gaseous necrosis on postoperative pathology. CONCLUSION: ERUS is helpful to evaluate the morphologic change of cervical carcinoma limited tothe pelvis in intra-arterial cisplatin chemotherapy.

46 knees with injured meniscus diagnosed by the use of history and physical examination as well as by arthrography were meniscectomized from January in 1974 to June in 1978. Statistical analysis of data obtained from the histories, physical examinations and arthrographic studies of 46 knees with a mean follow up 6 months after meniscectomy revealed as follows. 1. Lateral meniscus injuries were higher incidence than medial meniscus. 2. In the posterior horn of the medial meniscus and in the middle third of the lateral meniscus on the injured location were more frequently encountered. 3. To compare the results of twe methods of diagnosis were obtained with 67% accuracy by the use of history and physical examination and with 85% accuracy by arthrography 4. We should be able to diagnosis with 91% armed with a history and physical examination and an arthrogram. 5. As being the excellent results after meniscectomy were classified with 78%.

Author take off the pelvic bone from the cadaver and made the accruate reconstructed the pelvic bone as well as normal bone. Then author setted the pelvic bone into the specialized acrylic globe as the normal person erect position. For the acetabular posterior wall, projected the radiologic beam from the 0°to 45°cephalad direction and then pelvic bone rotated internally 0°~45°, each section is 5°. For acetabular anterior wall, projected the radiologic beam from 0° to 45° caudal direction and pelvic bone rotated externally 0°~45°, each section is 5° too. From the pelvic bone experiments, author get on the good radiologic angle for acetabular anterior and posterior wall. Ane then make the radiologic projection for normal person as the pelvic experiment. In pelvic bone model experiment, For acetabular anterior wall and anterior colum, external rotation 20°~30° caudal tilting 30°~45° angle projection has good visualization. For acetabular posterior wall and posterior column (including anterior column partially), internal rotation 15°~20° cephalad tilting 15°~30°angle projection has the good visualization. In normal person experiment, For acetabular anterior wall and anterior column, external rotation 20°caudal tilting 30°angle projection shows the good visualization. For acetabular posterior wall and column (including anterior column partially) internal rotation 20°cephalad tilting 30°angle projection shows good visualization. From the pelvic bone model and normal person experiments, the following conclusion are obtained. 1. For posterior wall and posterior column(including anterior column partially), internal rotation 20°, cephalad tilting 30°view is good. 2. For anterior wall and anterior column, external rotation 20°, caudal tilting 30°view is good.

Segmental fractures of the femoral shaft result from high energy trauma such as a traffic accident or falls, and it is frequently accompanied by multiple fractures and severe injuries to other organs. Thus it is very difficult to treat these fractures satisfactorily and several complications can be caused. Early operative intervention and rigid fixation is important to mobilize the patient and to ensure early rehabilitation. Nineteen cases of segmental fractures of the femoral shaft were treated with operative intervention(intramedullary nailing) and followed up between May 1989 and Nov. 1993.; minimal follow-up period was more than one year. Results were obtained as follows: 1. The methods of treatment were interlocking intramedullary nailing in 16 cases(colsed nailing in 7 cases, open nailing in 9 cases) and Kiintscher nailing in 3 cases. Bone grafts were done in 11 cases among 19 cases(8 cases in the interlocking nail group). 2. The closed interlocking intramedullary nailing could be obtained in more shortened operation time than in the open method. 3. There was earlier bone union time in the closed intramedullary nailing than in the open method with bone graft, but there was no statistical significance(SPSS/pc+progam). 4. There was a tendency of earlier bone union time in the proximal fracture site than in the distal fracture site.
