STUDY DESIGN: The treatment of a stable fracture around thoracolumbarjunction is a controversial subject. OBJECTIVES: To evaluate the result from long term follow-up of the stable spinal fracture around thoracolumbar junction according to the operation, osteoporosis and in situ extension bar, respectively. SUMMARY OF BACKGROUND DATA: The thoracolumbar junction is a transitional zone in which the kyphotic angle of thoracic spine is continued to the lordotic angle of lumbar splne. So it is prone to be injured biomechanically, and the stability of the spine around thoracolumbar junction is not determined yet. METHODS: We studied retrospectively 105 cases of the stable fracture around thoracolumbar junction from January 1985 to December 1995. The criteria of the stability were a compression fracture by Denis F., a bursting fracture without involvement of posterior column, a neural enchroachment of bony fragment below 30%, fracture without subluxation or dislocation in spinal junction. RESULTS: The most common cause was traffic accident and, the first lumbar vertebrate was common site. Below 30% of initial compression, the progression was not exceded 5% in operative group. But in nonoperative group, anterior compression was more progressed than initial compression over 5%. The degree of anterior compression was affected by osteoporosis and in situ extension bar just after injury. CONCLUSIONS: We suggest an anterior compression abode 30% in spinal body of thoracolumbar junction for an additional operative indication. The prognosis may be affected by osteoporosis and in situ extension bar.

6 patients underwnet CT-guided stereotactic biopsy or hematoma aspiration procedure for posterior fossa lesions. Trajectory for biopsy or aspiration was transcerebellar approach. The patients were placed under general endotracheal anesthesia and positioned prone or sitting. No complications were encountered in the postoperative period when this technique was used. Stereotaxic transcerebellar multiple biopsy can safely provide tissue conformation of the neoplastic nature of a posterior fossa lesion thought to be a tumor. In addition, hematoma aspiration has been demonstrated to be safe, reliable, and efficient.

The wandering spleen is a rare condition, in which the spleen is located in other than the left upper quadrant of the abdomen. The clinical manifestation is variable from asymptomatic to abdominal catastrophy due to torsion of the splenic pedicle. We experienced a case of torsion of wandering spleen in 8-year-old girl who admitted with fever, vomiting, abdominal pain, palpable left abdominal mass. She was diagnosed preoperatively with the aid of abdominal sonography and C.T. scanning. A splenectomy was performed and she made uneventful recovery. The case report illustrates some of the diagnostic and therapeutic considerations pertaining to wandering spleen with a brief review of related literature.

Implant materials, for examples, plaster of Paris, Bone cement and ceramics which are used experimentally to regain shape and function, act as a scaffold for bone growth and contribute to the healing processes at bone defect developed by trauma, infection and other causes. Therefore, the effect of plastei of Paris on the bone defects of adult rabbits may be an interesting subject, particularly in the orthopedic field. The authors carried out an experiment to study the effect of plaster of Paris on the bone defect, using 30 adult rabbits weighing fmm 3000-3500 gm, which were divided into 3 main gmups. (Each group was composed of 10 adult rabbits.). In Group 1, which was the control group, made a defect at the proximal metaphysis of the tibia, 6 mm×6 mm×6 mm in size, using a drill bit and filled by hematoma spontaneously. In Group II and Group IU, a defect was also made by the same method as in Group I and a piece of Gelfoam or plaster of Paris was inserted into the bone defect respectively. Then we studied the healing processes of the bone defect by sacrifying animals of each group at 6th and 12 th week after operation. The results of this experiment were as follows. 1. New bone formarion in the bone defect was poor in group I and Gmup Il, but it was good in Group III. 2. The plaster of Paris, filling into the defect, was absorbed and removed from the site of implantation continuously and stimulated the new bone formation. 3. The Gelfoam in Group II was more rapidly absorbed than plaster of Paris and didn't stimulate the new bone formation.

To evaluate the appearance rate of typhoid granuloma, a clinical and histological study was made on bone marrow smears or biopsies of 60 patients with proven typhoid fever. The results were as follws: 1) Sixty cases consisted of 34 cases of bacteriologically proved group, 10 cases of serologically proved group, and 16 cases of clinically suspected group. The positive culture rate from bone marrow fluid was the highest (70.6%) among specimens although it was obtained 1.6 days in average after the administration of antibiotics. 2) Fourth-eight cases by bone marrow smear revealed the M:E ratio of 3.93:1 in average, mild myeloid hyperplasia and 50.5% of appearance rate of typhoid cells. 3) Fourth-nine cases of bone marrow biopsy revealed 8 cases of typhoid granuloma, all of which belonged to the bacteriologically proved group. All these have no pathognomonic morphologic features. 4) Fourty cases of bone marrow examination of patients with FUO except typhoid fever revealed no typhoid cells in smear and 3 cases of granulomatous lesion from two patients with miliary tuberculosis and one patient with Hodgkin's lymphoma.

Wernickes encephalopathy is an illness characterized by mental disturbance, paralysis of eye movements and ataxia of gait. The specific factor for most, if not all, of these symptoms is a deficiency of thiamine. Wemicke's encephalopathy mostly occurs in developing countries when the patient is in a state such as nutritionally deprived state, anorexia nervosa, stomach cancer, long duration of parenteral nutrition. Wernickes encephalopathy was recognized as a complication of hyperemesis of pregnancy in 1914. Unfortunately, cases continue to occur. We present here a case of Wernickes encephalopathy in a 36-year-old pregnant woman. We discuss the clinical picture, histopathology, radiology, therapeutic management and prognosis with review of the literature.
