The purposes of operative treatment in unstable thoracolumbar and lumbar spine fractures are anatomical reduction and stabilization of the fractures and thus promote neurological recovery and early rehabilitation. To achieve these goals, complete preoperative assessment and recognition of the fracture pattern is necessary in addition to good surgical technique. The authors analyzed 47 cases of thoracolumbar and lumbar spine fractures operated from Jan. 1989 to Dec. 1991 at the Department of Orthopaedic Surgery, National Medical Center. All cases were classified according to Denis classification and in deciding the appropriate surgical approach, fracture type, stability, neurologic status and degree of deformity were all considered. Anterior approaches were performed in 23 cases of burst fracture and 3 cases of fracture-dislocation, and posterior approaches were performed in 1 case of compression fracture, 7 cases of burst fracture, 4 cases of seat-belt type injury and 5 cases of fracture-dislocation, In 3 cases of burst fracture and 1 case of fracture-dislocation, both anterior and posterior approaches were combined. With the analysis of postoperative changes in sagittal and coronal angle, translation and degree of rotation, we evaluated the results of operative reduction in terms of restoring normal anatomical configuration of injured spinal segments. So we tried to find the attributing factors in the operative reduction of the thoracolumbar and lumbar spine fractures and suggest the proper surgical approach that provides better reduction and stabilization.

PURPOSE: The Swedish Interactive Thresholding Algorithm (SITA) strategies is a new diagnostic tool of Humphrey automatic perimetry and has been reported to reduce testing time without loss of useful diagnostic information. To test the usefulness of this new diagnostic method, we compared the SITA and full threshold diagnostic method, which had been used previously. METHODS: Forty six patients (46 eyes) who were followed up for glucoma or ocular hypertension were in this study. Autoperimetry was performed using both SITA and full threshold strategies. RESULTS: The SITA showed shorter testing time (7.74+/-1.25 min) than the full threshold (14.4+2.43 min). There were significant differences between the full threshold MD (-8.06+8.11 dB) and SITA MD (-7.45 +/-8.32 dB), as well as full threshold PSD (4.47+/-2.50 dB) and SITA PSD (3.67+/-2.56 dB), when compared with data of greater than -12 dB MD respectively(p<0.05). Two cases showed changed diagnosis in GHT. CONCLUSIONS: SITA is a good test method with short test time. However, changing from full threshold to the SITA method should be reconsidered due to variation in the amount of field defect depending on the damage progression and the possibility of changes in diagnosis.

Endodermal sinus tumor of the mediastinum is a very rare malignant tumor, usually affecting young adolescents, and its histologic findings are characteristic as that of gonadal germ cell origin. We describe the cytologic finding of fine needle aspiration of mediastinal endodermal sinus tumor in a 19-year-old male patient, comparing with tissue section. The tumor cells in smears were usually in tight clusters with large overlapping cells, which were arranged in a papillary or microacinar pattern, suggesting carcinoma. The tumor cells were large, round or oval with a small amount of cytoplasm which was occasionally vacuolated and had indistinct border. The nuclei were large, pleomorphic, and vesicular with large promi- nent nucleoli. The tissue sections showed typical findings of endodermal sinus tumor. Careful correlation of cytological findings and the serum alpha-fetoprotein level would be helpful to confirm the diagnosis.

A case of invasive cribriform carcinoma of the breast is presented with fine need- le aspiration cytologic features. The aspiration was performed from a papable 2.0cm mass in the upper outer quadrant of the right breast in a 53 year-old woman. The aspirate showed cellular smear composed of larger three dimensional tight clusters, smaller monolayered loose clusters, and many individual cells on the clean background. In the clusters, the tumor cells were bordering central lumina, quite similar to the cribriform in histology. The tumor cells in the clusters and individual tumor cells had uniform, small and round nuclei. The chromatin was finely granular, and nuclear membrane was smooth. No discernible nucleoli were present (nuclear grade 1-2). Unless the abundance of individual cells and the cribriform growth pattern are recognized in the smear, the cytologic diagnosis of invasive cribriform carcinoma is difficult.

So-called sclerosing hemangioma of the lung is a rare benign neoplasm which usually presents with a coin lesion detected through routine chest X-ray. We report two cases showing characteristic cytologic appearances which have been rarely reported. Both cases were young females with coin lesions in the lung. Fine needle aspiration of each case revealed unique but some different cytologic features. Case 1 showed bland-looking polygonal epithelial cells resembling bronchioloalveolar cells having pre- dominantly papillary configurations with loosely arranged solid sheets or isolated cells. Cytoplasms were plump, cyanophilic, and finely granular, with eccentric nuclei, The nuclei were usually monotonous, round-to-ovoid, and vesicular with a small but conspicuous nucleolus. In comparison to case 1, case 2 revealed largely loose pavement-like solid sheets or clusters rather than papillary patterns in the hemorrhagic background. The size of tumor cells were a little smaller than that of case 1. Bronchioloalveolar carcinoma and papillary adenocarcinoma of metastatic origin were considered to be one of the important differential diagnoses with these cytologic features. Histologically, both cases exhibited findings compatible with so-called sclerosing hemangioma of the lung.

Since Hadra first used metalic internal fixation in the human spine with wire loop in 1895, various implants have been used. Knodt rod was designed on the principle that the distraction produced a localized flexion attitude in the area to be fused, thus increasing the size of the intervertebral foramina and decreasing the risk of intraforaminal encroachment on the nerve root. We have performed the posterolateral fusion with or without Knodt rod as a primary procedure in spondylolysis and spondylolisthesis of lumbar spine, which required arthrodesis of more than one level. For period of 8 1/2 years' from Sep. 1977 to Apr. 1986, 12 cases of diseased spine were treated with posterolateral fusion without Knodt rod, and 13 cases were treated with posterolateral fusion using Knodt rod. We compared with two groups, and the following results were obtained. 1. Solid bony fusion was 100% in posterolateral fusion with Knodt rod, and 92% without Knodt rod. 2. An average period of post-operative immobilization was 2 months in cases with Knodt rod, and 2.5 months without Knodt rod. 3. In posterolateral fusion with Knodt rod, 4 cases with the root symptoms were all improved. In posterolateral fusion without Knodt rod, 6 cases with root symptoms, were all improved. But in 1 case without the root symptoms, developed the root symptoms. 4. No significant changes in radiologic evaluation were found between posterolateral fusion with Knodt rod and without Knodt rod. 5. Post-operative complications developed in 4 cases (31%) with Knodt rod, and 6 cases (50%) without Knodt rod. 6. Clinically, the satisfactory results were 100% with Knodt rod, and 83% without Knodt rod.
