The authors report the experience of twenty patients of transpedicular Zielke instrumentation after anatomical reduction of the spondylolisthesis. Anstomical reduction was done with the aid of temporary application of Harrington distraction rod, and the reduced segment was fixed with transpedicular Zielke instrumentation. And, anterior interbody fusion was supplemented in a single stage operation. Follow up period was between 13 to 25 months after operation with the average of 19 months. 1. The age of the patients was 38 years in average ranging from 11 to 61 years. 2. Types of the spondylolisthesis were spondylolytic type in 11 cases, degenerative type in 6 cases, dysplastic type in 1 case and pathologic type in 2 cases. 3. The level of the lesion were L5-Sl in 12 cases, L4-5 in 7 cases and L3-4 in 1 case. 4. Pre-operative clinical feature included low back pain in 95%, radiating pain in 65%, and neurological claudication in 45%. 5. The average percentage of slippage was changed from 24% preoperatively to 6% postoperatively and to 8% at the final follow up. The initial correction rate was 75% and the amount of correction loss during the follow up period was 11% in average. 6. Slip angle was changed from 3°preoperatively to −3°poetoperatively and to 0°at the end of follow up. In the 12 cases with local kyphosis, average slip angle of 14°preoperatively was improved to 2°postoperatively, and to 7°at the end of follow up. 7. Bony fusion was obtained in 19 cases within 4 to 6 months. 8. There were 2 cases of metal failure with considerable loss of reduction ; one patient with pathologic spondylolisthesie due to active tuberculous spondylitis required re-operation and another patient showed fusion eventually in the redisplaced position. Other complication included 1 transient dysuria, 1 ileus and 2 meralgia paresthetics. 9. Clinical symptoms were improved in 95%. Follow up result of the operation according to Gill's criteria were excellent 65%, good 25%, fair 5%, and poor 5%.

STUDY DESIGN: Sixteen patients with congenital kyphoscoliosis were evaluated the clinical and radiological results according to the treatment method. OBJECTIVES: To provide a guideline for surgical treatment of congenital kyphoscoliosis SUMMARY OF LITERATURE REVIEW: Congenital kyphoscoliosis is an abnormal coronal and sagittal curvature of spine that is caused by the presence of vertebral anomalies, which causes a significant deformity and disability. Correction of the deformity is challenging and accompanied by high risk of complications. Many methods of operative treatment were recommended with various results. MATERIALS & METHODS: We reviewed 16 patients of congenital kyphoscoliosis who were operated from 1984 to 1997, and follow-up periods were over 12 months in all. The average age of surgery was 12 years (ranged from 4 to 20 years). Nine cases were operated by excision of quadrant hemivertebra through combined anterior & posterior approach and 6 cases were treated only by posterior instrumentation and one underwent posterior on bloc spondylectomy. RESULTS: The type of curves were thoracic in 5, thoracolumbar in 9, lumbar area in 2 patients. Average angle of kyphosis was 55 degree preoperatively, 25 degree postoperatively, and 39 degree at the follow up study. Average angle of scoliosis was 48 degree, 22 degree, and 27 degree, respectively. In 9 cases corrected by excision of quadrant hemivertebra; kyphotic angle was changed from 62degrees preoperatively, to 22degrees postoperatively and to 36 degree at the end of follow up study, while scoliotic angle was changed from 47degrees, to 12degrees and to 21degrees, respectively. In 6 cases corrected by posterior instrumentation kyphotic angle was changed from 52degrees preoperatively, to 33degrees postoperatively and to 48degrees degree at the follow up study, while scoliotic angle was changed from 53degrees, to 33degrees and to 37degrees, respectively. CONCLUSION: Excision of quadrant hemivertebra through combined anterior and posterior approach or posterior instrumentation were resulted in significant loss of correction during the remaining growth period due to the secondary change of adjacent vertebrae. So, to obtain better correction and to reduce the recurrence of deformity, more aggressive approach including the concept of three dimentional osteotomy involving the upper and lower adjacent curve may be considered.

We have studied the function of lymphokines on human tonsillar B cell prolifertion and differentiation. B cells were stimulated with Staphylococcus aureus Cowanl (SAC) or anti- bead. The followings showed the results of this study. 1) In B cell activation, SAC induced B cell DNA synthesis but anti-mubead did not. SAC could activate and proliferate B cells. Minimal number of B cells were required to proliferate effectively. 2) In B cell proliferation, SAC could proliferate B cell in the abscence of lymphokines. Exogenous IL-2 or IL-4 enhanced B cell proliferation. The roles of IL-2 were very important in B cell proliferation. The effect of IL-4 on the IL-2 induced B cell proliferation was inhibitory in SAC-B cells. IL-4 could enhance the proliferation of anti-mu bead activated B cells. 3) In B cell differentiation, IL-2 was a major factor to differentiate SAC activated B cells, but IL-4 did not. IL-6 had a synergistic effect on the differentiation. The results of this study showed that the different signal transduction mechanisms were involved in B cell proliferation and differentiation. The B cell resposes to lymphokine were different, and it is depend upon antigens or mitogens.
